Pythagorean theorem:
Is a triangle with the following side lengths a right triangle? Why?
a = 8
b = 15
c = 17
Example:
This does/does not make a right triangle because...

Answer:

35

Step-by-step explanation:

Answer:

b = 35

Step-by-step explanation:

a and b make a right angle

a+b = 90

55 + b = 90

subtract 55 from each side

55-55 +b = 90-55

b = 35

Answer:

x = 16

y = 16 sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/hyp

sin 60 = y/ 32

Multiply each side by 32

32 sin 60 = y

32 ( sqrt(3) /2) = y

16 sqrt(2)

cos theta = adj/ hyp

cos 60 = x /32

32 cos 60 = x

32 (1/2) =x

16 =x

Answer:

16

Step-by-step explanation:

YOU NEED A CALCULATOR TO SOLVE THIS!

To solve this you need to use SOH-CAH-TOA

Do cos60° to find x

         [tex]cos60 = \frac{x}{32}[/tex]

Multiply both sides by 32 to get x alone

[tex]32(cos60) = x[/tex]

Now put 32(cos60) into your calculator

The answer you get is 16

Final answer:

To rewrite 1/6 with a denominator of 18, multiply both the numerator and the denominator by 3, resulting in the equivalent fraction 3/18. To confirm its equivalence, simplify 3/18 back to 1/6 by dividing both the numerator and the denominator by 3.

Explanation:

How to Rewrite a Fraction with a New Denominator

To rewrite the fraction 1/6 with a denominator of 18, we need to find a number that we can multiply both the numerator and the denominator of the fraction by so that the denominator becomes 18. Since 6 times 3 equals 18, we will use 3. The fraction then becomes:

(1 x 3) / (6 x 3) equals 3/18.

Verifying the Equivalent Fraction

To verify that 3/18 is indeed equivalent to 1/6, we can simplify 3/18 by dividing both the numerator and denominator by their greatest common factor, which is 3:

3 ÷ 3 / 18 ÷ 3 = 1/6.

This confirms that 3/18 is equal to 1/6 because it simplifies back to the original fraction.

The surface area of the larger sphere is 366.2496 square centimeter.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, two spheres have volumes of 87 cm³ and 647 cm³.

We know that, the volume of a sphere = 4/3 πr³

Here, 647 cm³=4/3 πr³

647 = 88/21 r³

r³ = (647×21)/88

r³ = 154.39

r = 5.4 cm

We know that, surface area of a sphere is 4πr².

The surface area of the larger sphere = 4×3.14×5.4²

= 366.2496

Therefore, the surface area of the larger sphere is 366.2496 square centimeter.

Step-by-step explanation:

Start at 6 on the y axis. Draw an arrow so that it horizontally moves to the blue curve. Then draw an arrow straight down to vertically drop to x = 4

See the diagram below.

Follow this process in reverse to see that x = 4 leads straight up to the blue curve, and then to the left to land on y = 6. Keep in mind that the inverse reverses the input and output process, which is why I started with y instead of x.

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression, f⁻¹(6) is 4.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The value of the expression can be found as shown below,

y = f(x)

When the value of y is 4, the value of x is 6, therefore, we can write f(6)=4.

Now, the given expression can be simplified as,

f⁻¹(6) = 1 / f(6)

       = 1 / 4

       = 0.25

Hence, the value of the expression, f⁻¹(6) is 4.

Answer: 2z+4/y+7

Step-by-step explanation:

We are trying to solve for x

7x-2z=4-xy

Add xy to both sides:

7x-2z+xy=-xy+4+xy= xy+7x-2z=4

Then you add 2z to both sides:

xy+7x-2z+2z=4+2z

xy+7x=2z+4

Then you factor out variable x

x(y+7)=2z+4

You divide both sides by y+7

x(y+7)/y+7= 2z+4/y+7

Which we would get x=2z+4/y+7

Like terms are those terms that are having the same variables, also the variables are of the same order as well. The value of the x can be written as (4 + 2z)/(7 + y).

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

7x - 2z = 4 - xy

Bring like terms together,

7x + xy = 4 + 2z

Take x as common from the left side of the equation,

x(7 + y) = 4 + 2z

x = (4 + 2z)/(7 + y)

Hence, the value of the x can be written as (4 + 2z)/(7 + y).

To find the value of t, apply the exponent rules and simplify to get t = [tex]j^{59[/tex], assuming j is not zero.

The value of t in the equation [tex](j^{-12})^{-5} = j \times t[/tex] can be found by understanding the properties of exponents. Since the equation involves a base raised to an exponent that is also raised to another exponent, one would apply the rule that states [tex](a^n)^m = a^{(n \times m).[/tex] Thus, simplifying gives us [tex]j^{(12 \times 5)} = j \times t \space or j^{60} = j \times t[/tex] Now, assuming that j is not 0, we divide both sides by j to isolate t, resulting in [tex]t = j^{59[/tex], and j will not be equal to zero, hence J [tex]\neq[/tex] 0.

Answer:

The rating of a brand that costs $3.00 per bag is 7.

Step-by-step explanation:

A simple linear regression equation is used to estimate the value of the dependent variable based upon the independent variable.

The general form of a simple linear regression equation is:

[tex]y=a+bx[/tex]

Here,

y = dependent variable

x = independent variable

a = intercept

b = slope

The output of the least squares regression analysis for predicting rating from price is provided.

So, the dependent variable is the ratings and the independent variable is the price.

The regression equation for predicting rating from price is:

[tex]y=-0.39+2.52x[/tex]

Predict the rating of a brand that costs $3.00 per bag as follows:

[tex]y=-0.39+2.52x[/tex]

  [tex]=-0.39+(2.52\times \$3.00)\\=-0.39+7.56\\=7.17\\\approx 7[/tex]

Thus, the rating of a brand that costs $3.00 per bag is 7.

Answer:

surface are: 300 cm2

volume: 450cm3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:

Surface area of a box = 2wl + 2hw + 2 lh

Where w is the width of the box, l is the length of the box, and h is the height of the box.

The top sides and bottom have only length and width, since there is no top side, the surface area is equal to the outer 5 surfaces.

S = wl + 2hw + 2 lh

Replacing with the values given:

S = (15x10)+ 2(3x10)+ 2(15x3)

S = 150+60+90=300 cm2

For the volume we simply apply:

Volume of a rectangular prism: length x width x height

V = 15x10x3 = 450cm3

Answer:

3,1,5,4,8,6 is 1.83 for mean absolute deviation

Step-by-step explanation:

The student correctly calculated the mean and the absolute deviations from the mean, but did not divide the sum of these by the number of data points to find the mean absolute deviation. The correct mean absolute deviation is 11 divided by 6, equal to 1.83 (rounded to two decimal places).

Based on your computations, it looks like you did correctly compute the mean absolute deviation (MAD). The first step is to find the mean (average) of the data set, which you correctly found to be 4.5 by summing the data points (3, 1, 5, 4, 8, 6) and dividing by the number of data points (6). Then, you correctly computed the absolute deviations from the mean for each data point (|1-4.5|, |3-4.5|, |4-4.5|, |5-4.5|, |6-4.5|, |8-4.5|), and summed these to get a total absolute deviation of 11. Finally, you divided this total by the number of data points (6) to find the mean absolute deviation. However, you missed this final division step in your calculations. The MAD should be 11/6 = 1.83 (rounded to two decimal places).

Final answer:

To determine the best deal, compare unit prices by dividing the price by the size of the items. Spend the $10.00 according to needs and preferences.

Explanation:

In order to determine which size is the best deal, Joy and John need to compare the prices per unit of the items they want to buy. They should divide the price of each item by its corresponding size to calculate the unit price. The item with the lowest unit price would be the best deal.

For example, if Joy wants to buy a 16oz bottle of soda for $1.50 and John wants to buy a 20oz bottle for $2.00, the unit price for Joy's soda would be $1.50/16oz = $0.09/oz, while the unit price for John's soda would be $2.00/20oz = $0.10/oz. Therefore, the 16oz bottle would be the best deal as it has a lower unit price.

As for how they should spend the $10.00, it would depend on their needs and preferences. They could evenly split the money and buy items separately, or they could pool their money together and buy a larger item.
