Answer:

m∠A = 90°, m∠B = 60°, m∠C = 30°

Step-by-step explanation:

step 1

see the attached figure to better understand the problem

In this problem we have a right triangle, because the Pythagorean Theorem is satisfied

so

[tex]BC^2=AB^2+AC^2[/tex]

[tex]24^2=12^2+(12\sqrt{3}) ^2\\\\576=576[/tex]

therefore

[tex]m\angle A=90^o[/tex]

step 2

Find the measure of angle B

we know that

In the right triangle ABC

[tex]cos(B)=\frac{AB}{BC}[/tex] ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

[tex]cos(B)=\frac{12}{24}[/tex]

[tex]m\angle B=cos^{-1}(\frac{12}{24})=60^o[/tex]

step 3

Find the measure of angle C

we know that

[tex]m\angle B+m\angle C=90^o[/tex] ----> by complementary angles

we have

[tex]m\angle B=60^o[/tex]

substitute

[tex]60^o+m\angle C=90^o\\m\angle C=30^o[/tex]

therefore

m∠A = 90°, m∠B = 60°, m∠C = 30°

Answer:

1 hour 20 minutes

Step-by-step explanation:

It takes twenty minutes to finish a quarter of one level. Which indicates that it would take one hour and twenty minutes to finish said level by simply multiplying twenty by four.

George will complete a level on his computer games in 1 1/3 of the hours.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that he finished 1/4 of a level on his computer games in 1/3 of an hour at this rate.

Let x the number of hours will it take to complete on a level

According to the given question, we can write the ratio would be as:

1/4 of a level : 1/3 of an hour = 1 level : x hour

⇒ (1/4) / (1/3) = 1/x

Apply the cross-multiplication operation,

⇒ x = (1/3) × 4

⇒ x = 4/3

⇒ x = 1 1/3

Therefore, there will be 1 1/3 of the hours it takes to complete a level.

Answer:

The answer that gives the best estimate is (1,1)

Step-by-step explanation:

i) As can be seen on of the lines intercepts the y axis at (0,-1). So the y

 intercept or [tex]c_{1}[/tex] = -1. Therefore the equation for this line can be written as

 y = [tex]m_{1}[/tex] x + [tex]c_{1}[/tex]    ⇒    y = [tex]m_{1}[/tex] x - 1 . It can also be seen from this graph that the

 line passes through the point (2 , 2). Substituting these values for x and y  

 respectively we get  2 = 2[tex]m_{1}[/tex] - 1    ∴ [tex]m_{1}[/tex] = [tex]\frac{3}{2}[/tex].  The equation of the first line

 can be written as y = [tex]\frac{3}{2}[/tex] x - 1   ⇒ 2y - 3x = -2

ii) As can be seen on the other line the intercept on the y axis is at (0,2). So

  the y  intercept or [tex]c_{2}[/tex] = 2. Therefore the equation for this line can be  

  written  as  y = [tex]m_{2}[/tex]x + [tex]c_{2}[/tex]    ⇒    y = [tex]m_{2}[/tex] x + 2 . It can also be seen from this  

   graph that  the  line passes through the point (1 , -1). Substituting these

   values for x and  y   respectively we get  1 = 1[tex]m_{2}[/tex] + 2    ∴ [tex]m_{2}[/tex]  = -1 .  The

   equation of the second line  can be written as y = - x + 2   or x + y = 2

iii) Solving the two equations of the two lines respectively as found in i) and

  ii)  we get y = 0.8. We multiply equation in ii) by 3 to get 3x + 3y = 6 and  

  when we add this to equation in i) we get 5y = 4 which means that y = 0.8.

  If we substitute this value in ii) we get 0.8 + x = 2 , therefore x = 1.2.

iv) Therefore we get the solution of the two lines, which is the intersection

    of the two lines as (1.2, 0.8). So the answer that gives the best estimate

    is (1,1)

Answer:

It is irrational

Step-by-step explanation:

if you combine a rational and irrational number it cannot be rational.

Adding a rational and an irrational number always results in an irrational number. The rational number doesn't affect the irrationality of the irrational number.

The result of adding a rational and an irrational number is always an irrational number. For example, if you add the rational number 2 (which can be expressed as a ratio of two integers) and the irrational number sqrt(2) (which cannot be expressed as a ratio of two integers).

The result is 2 + sqrt(2), which is an irrational number.

Because the rational number doesn't affect the irrationality of the irrational number, the sum remains irrational.

The solution is [tex](-1,5)[/tex] and [tex](7,-3)[/tex]

Step-by-step explanation:

The expression is [tex]x^{2} +y^{2} -x+3y-42=0[/tex] and [tex]x+y=4[/tex]

Using substitution method we can solve the expression.

Let us substitute [tex]x=4-y[/tex] in [tex]x^{2} +y^{2} -x+3y-42=0[/tex]

[tex](4-y)^{2} +y^{2} -(4-y)+3y-42=0[/tex]

Expanding and simplifying the expression, we get,

[tex]\begin{array}{r}{16-8 y+y^{2}+y^{2}-4+y+3 y-42=0} \\{2 y^{2}-4 y-30=0}\end{array}[/tex]

Let us use the quadratic equation formula to solve this equation,

[tex]\begin{aligned}y &=\frac{4 \pm \sqrt{16-4(2)(-30)}}{2(2)} \\&=\frac{4 \pm \sqrt{16+240}}{4} \\&=\frac{4 \pm 16}{4} \\y &=1 \pm 4\end{aligned}[/tex]

Thus, [tex]y=5[/tex] and [tex]y=-3[/tex]

Substituting y-values in the equation [tex]x+y=4[/tex], we get the value of x.

For [tex]y=5[/tex] ⇒ [tex]x=4-5=-1[/tex]

For [tex]y=-3[/tex] ⇒ [tex]x=4+3=7[/tex]

Thus, the solution set is [tex](-1,5)[/tex] and [tex](7,-3)[/tex]

Answer:

time = distance / speed

time = 200/10

= 20

Step-by-step explanation:

The time taken to travel a distance of 200 Km will be 5.5 hours.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Given that the speed is 10 m/s and the distance to be travelled is 200 km.

The time will be calculated as below,

T = Distance / Speed

T = 200000/ 10

T = 200000/10 x 3600

Brad spends about the same amount of time doing homework as he does watching videos. The other statements are not true.

The circle graph shows how Brad spends his time outside of school. To determine which statements are true, we need to compare the different activities.

A. To compare working and homework, we can see that Brad spends about ⅔ of his time working and ⅓ of his time on homework. So, A is not true since Brad spends more time on homework than working.

B. To compare watching videos and reading with playing the piano and soccer, we can see that Brad spends about 1/6 of his time on watching videos and reading, and about 3/6 of his time on playing the piano and soccer. So, B is not true since Brad spends more time playing the piano and soccer than watching videos and reading combined.

C. To compare doing homework and watching videos, we can see that Brad spends about ⅓ of his time on both activities. So, C is true since Brad spends about the same amount of time doing homework as he does watching videos.

D. To compare playing piano with playing football and soccer combined, we can see that Brad spends about 1/6 of his time on playing piano, and about 4/6 of his time on playing football and soccer combined.

Step-by-step explanation:

Given:

Bernie, Eddy and Gery share £450.

Bernie gets twice as much as Eddy.

Eddy gets three times as much as Gery.

So,

Let Gery gets 'x' share of the amount.

Then,

Eddy's share will be '[tex]3x[/tex]'

and

Bernie's share will be [tex]2\times 3x=6x[/tex]

Answer:

The slope of given relationship is 7 and it is not - 3  

Step-by-step explanation:

Given as :

The distance cover while walking = d = 21 miles

The speed rate of walking = s = 3 miles per hour

Let The time taken to cover 21 miles = t hours

Now, According to question

∵ Distance = Speed × Time

So, Time = [tex]\dfrac{\textrm Distance}{\textrm Speed}[/tex]

Or, t = [tex]\dfrac{d}{s}[/tex]

Or, t = [tex]\dfrac{\textrm 21 miles}{\textrm 3 miles per hour}[/tex]

∴  t = 7 hours

So,  The time taken to cover 21 miles = t = 7 hours

i.e slope of the given relationship = 7

Answer:

see explanation

Step-by-step explanation:

The side of the square = x + 2, thus area is equal to

(x + 2)² ← expand using FOIL

= x² + 4x + 4

Given area = 7 then

x² + 4x + 4 = 7 ( subtract 4 from both sides )

x² + 4x = 3 ← as required

Answer:

the area of the square ABCD = 7

on the other hand, the area of the square ABCD = (2+x)² = x² + 4x + 4

then x² + 4x + 4 = 7

then x² + 4x + 4 = 4 + 3

then x² + 4x = 3

Step-by-step explanation:

To evaluate the expression 4c - x with c=5 and x=-4, substitute the values to get 4*5 - (-4), which simplifies to 20 + 4, resulting in a value of 24.

To evaluate the expression 4c-x when c=5 and x=-4, substitute the given values for the variables c and x into the expression.

Step 1: Substitute c = 5 into the expression.

4 × 5 - x

Step 2: Substitute x = -4 into the expression.

4 × 5 - (-4)

Step 3: Carry out the multiplications and additions.

20 - (-4) = 20 + 4

Step 4: Add the numbers.

20 + 4 = 24

Therefore, when c = 5 and x = -4, the value of the expression 4c - x is 24.

The value of the expression 4c-x when c=5 and x=-4 is 24.

To evaluate the expression (4c - x) when (c = 5) and (x = -4), follow these steps:

1. Substitute (c = 5) into the expression: [tex]\(4 \times 5 - x\)[/tex]

2. Substitute (x = -4) into the expression: [tex]\(4 \times 5 - (-4)\)[/tex]

3. Simplify the multiplication: (20 - (-4))

4. Simplify further by changing the double negative to addition: (20 + 4).

5. Add the numbers: (20 + 4 = 24).

Therefore, when (c = 5) and (x = -4), the value of the expression (4c - x) is (24). The process involves substituting values, simplifying, and performing addition to obtain the final result.
