there are between 24 to 40 students in a class. the ratio of boys to girls is 4:7. how many students are in the class.

Answer:

[tex]y=3(2)^{x-5}+6[/tex]

Step-by-step explanation:

Let the equation of the exponential function with base 2 is,

[tex]y=a(2)^{x+c}+d[/tex]

Here, a = vertical stretch

c = Horizontal shift

d = Vertical shift

If this function has a vertical stretch by a factor of 3,

Equation will be,

[tex]y=3(2)^{x+c}+d[/tex]

If this function has a shift of 5 to the right,

Equation of the function will be,

[tex]y=3(2)^{x-5}+d[/tex]

If this function has a shift of 6 units upwards,

[tex]y=3(2)^{x-5}+6[/tex]

Answer:

7A. x = 6

7B. m∠ABC = 135°

Step-by-step explanation:

7A. I forget what the rule is called specifically, but the opposite angle is always congruent. So, you simply end up solving for x when you set the equation to equal 45.

7B. Use the supplementary rule, which basically states that two angles on a flat plane, when adjacent, equal 180°. So, 180 - 45 = 135.

God, my terminology is awful, but that's besides the point.

answer

11.3 cm

steps

what is h cm to angle 37°=it is an opposite side

what is 15 cm to angle 37°=it is an adjecent side

opposite and adjecent form a tan

.°. opp/adj = tan(37°)

h/15 = tan(37°)

h = 11.3 cm

126 in cubed. - pyramid

378 in cubed. - prism

Step-by-step explanation:

Volume for pyramid: 1/3(B)(h)

This pyramid 1/3(42)(9)

126 in cubed.

Volume for prism: B(h)

This prism: (42)(9)

378 in cubed.

2.) The cube's volume

length ⋅ width ⋅ height

The triangular prism's volume is

l⋅w⋅h/3

9x6x7= 378

Answer:

3 qt

Step-by-step explanation:

Let's stick to one unit to facilitate things. I'm going to use quarts as the unit.

1 gal = 4 qt

Initial value = 3 gal 2 qt = 14 qt

Change = 2 gal 3 qt = 11 qt

14 qt - 11 qt = 3 qt

y = a(x-h)² + k is a vertical parabola.

If a is positive, the parabola opens upwards.

If a is negative, the parabola opens downwards.

The vertex is at (h, k)

Answer:

40

Step-by-step explanation:

SO im guessing if its the full graph one box counts 1.

So the top side counts 8

The left one is 15

The perimeter means adding all the sides together.

We already have 2. But finding the hypotenuse would not be easy from graph so we will use Pythagorean theorem.

a^2+b^2=c^2

8^2+15^2 = c^2

64+225 = c^2

289 = c^2

c = 17

so the perimeter is 8+15+17 = 40

Answer: x=15/2

Step-by-step explanation: Divide both sides by 4 so 64/4  Simplify 64/4 ​to  16. 2x=16−1 2x=15 Divide both sides by 2  x=  

15/2

Answer:

see explanation

Step-by-step explanation:

Given that p is an odd number , then

p² is always an odd number

Adding 1 to an odd number gives an even number.

So p² + 1 is always even for p odd

If x + 3/4 = 1 then the point on the number line shown figure is B.

We have given that,

if x + 3/4 = 1 then which point on the number line shown below could be x.

A number line is a picture of a graduated straight line that serves as abstraction for real numbers, denoted by R. Every point of a number line is assumed to correspond to a real number and every real number to a point.

Therefore, if x + 3/4 = 1 then the point on the number line shown figure is B.
