Explain how you would use mental math to express 16/25 as a percent???

Answer:

Linear

y = -30x + 100

Step-by-step explanation:

The table has a set of inputs with matching outputs. The behavior of the outputs will determine the type of function. The outputs appear to descend at a constant subtraction rate of -30 each time.

70 - 30 = 40

40 - 30 = 10

10 - 30 = -20

etc.

A constant addition or subtraction rate is a slope. Since the function has a slope, this is a linear function.

To write the function you'll need a slope and a y-intercept. Recall, the y-intercept is where x = 0. This is not in the table but can be found by reversing the process by adding 30 + 70 = 100.

Substitute m = -30 and b = 100 into y = mx+b for the equation.

y = -30x + 100

Answer:

Step-by-step explanation:

the answer is f(x)= 100-30x

Answer:

[tex]\frac{24}{7}=b[/tex]

Step-by-step explanation:

We are given a right angled triangle.

Hypotenuse = c = [tex]\frac{25}{7}[/tex]

Base = a = 1

Now we are supposed to find the perpendicular i.e. b

So, we will use Pythagoras Theorem  :

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex]c^2=b^2+a^2[/tex]

[tex](\frac{25}{7})^2=b^2+1^2[/tex]

[tex]\frac{625}{49}=b^2+1[/tex]

[tex]\sqrt{\frac{625}{49}-1}=b[/tex]

[tex]\frac{24}{7}=b[/tex]

Hence the missing length is [tex]\frac{24}{7}[/tex].

Answer:

s = ∛729 in³

Step-by-step explanation:

Since the volume is 729 in³, our equation can be plugged into:

729 = s³.

Isolate s by cube rooting each side: ∛729 = s.

Basically you have to find the graph that goes through the middle of the line or points to it.

Answer:   [tex]\bold{2\sqrt[3]{15} }[/tex]

Step-by-step explanation:

[tex]\sqrt[3]{10} \cdot \sqrt[3]{12} =\sqrt[3]{2\cdot 5\cdot 2\cdot 2\cdot 3} =2\sqrt[3]{3\cdot 5} =\boxed{2\sqrt[3]{15}}[/tex]

Check the picture below.

so then, let's notice, this triangular prism is really just 2 triangles and 3 rectangles stacked up to each other at the edges.

so if we simply get the area of each of those figures, and sum them up, that'd be the area of the prism.

notice, the triangles have a base of 4 and a height/altitude of 3.

[tex]\bf \stackrel{\textit{2 triangles}}{2\left[ \cfrac{1}{2}(4)(3) \right]}~~+~~\stackrel{\textit{inclined rectangle}}{(5\cdot 11)}~~+~~\stackrel{\textit{ground rectangle}}{(4\cdot 11)}~~+~~\stackrel{\textit{standing rectangle}}{(3\cdot 11)} \\\\\\ 12+55+44+33\implies 67+77\implies 144[/tex]

A I think cuz both are multiplied by 0

Check the picture below.

now, let's notice the triangle on the base.... is an isosceles, two sides are twins, and therefore, the two angles they make out are also twins, so, if the central angle is 100°, the other angles are each 80°/2, namely 40°, therefore, using the law of sines,

[tex]\bf \textit{Law of sines} \\\\ \cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{sin(100^o)}{2.5}=\cfrac{sin(40^o)}{r}\implies r\cdot sin(100^o)=2.5\cdot sin(40^o) \\\\\\ r=\cfrac{2.5\cdot sin(40^o)}{sin(100^o)}\implies \boxed{r\approx 1.63}[/tex]

now, let's notice the shaded triangle, namely the one with 35°, is a right-triangle, namely one angle is 35°, another 90°, so the last one must be 55°.

the opposite side to the 35° is "r", which we know is about 1.63, so again, let's use the law of sines to find the side "h",

[tex]\bf \cfrac{r}{sin(35^o)}=\cfrac{h}{sin(55^o)}\implies r\cdot sin(55^o)=h\cdot sin(35^o) \\\\\\ \cfrac{r\cdot sin(55^o)}{sin(35^o)}=h\implies \cfrac{1.63\cdot sin(55^o)}{sin(35^o)}\approx h\implies \boxed{2.33\approx h} \\\\[-0.35em] ~\dotfill\\\\ \textit{volume of a circular cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r\approx 1.63\\ h\approx 2.33 \end{cases}\implies V\approx \cfrac{\pi (1.63)^2(2.33)}{3}\implies \blacktriangleright V\approx 6.48 \blacktriangleleft[/tex]

Step-by-step explanation:

A statistical question has to be a question that can be answered by collecting data that varies.

Answer:

B.   What are the shoe sizes of players on the soccer team?

Step-by-step explanation:

A statistical question is one that can be answered by collecting data and where that data will vary.

We do not need to collect data to determine the number of questions on Ben's math test.

There is no variability in the number of chocolates Bertha sells in one day, nor in the number of students in Kathy's class.

To determine the shoe sizes of players on the soccer team, we must collect the data and the data will vary from player to player.  This is the statistical question.

Answer:

Surface area = 207.24 in²

Step-by-step explanation:

Remember to always convert the diameter into a radius.

D = 6 in (divide it by two to get the radius) R = 3 in

Radius = 3 in

Formula:

SA = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex]r²

Solution:

SA = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex]r²

SA = 2(3.14)(3)(8) + 2(3.14)(3)

SA = 2(3.14)(3)(8) + 2(3.14)(9)

SA = 150.72 + 56.52

SA = 207.24 in²

Answer: About 27.01

Step-by-step explanation: The way to find the diagonal is to multiply one side of the square by the sq. rt. of 2. First, we had to find one side of the square, which would be 76.4 divided by 4, then multiply that by the square root of 2.

76.4 / 4 = 19.1

19.1 x sq. rt. of 2 = 27.0114790413, or about 27.01

Answer:

Part A: Up 9

Part B: Up 6

Step-by-step explanation:

Part A: The graph appears to be a cosine graph since it starts at a peak on the y-axis. Normally a cosine graph starts at (0,1). This graph begins at (0,10). It has been shifted up y a translation by 9.

Part B: Each trig equation has a basic structure f(x) = a sin (x+b) + k where:

A vertical translation is a vertical shift and is represented by the value in k added outside of the function. In the equation f(x) = 2sin(θ + 120°) + 6, k = 6. The vertical translation is 6.
