HELP PLEASE! Im struggling

Answer:

384

Step-by-step explanation:

The formula for the volume is Area of Base * H / 3

The area of the base is 144

If you draw the height from the peak, you will get a right triangle with side length 6 and hypotenuse 10

Pythagorean Theorem, and the height is 8

144 * 8 / 3 = 384

Hope this helps.

Answer:

9

Step-by-step explanation:

Since the value is negative, that means that missing integer has to be 1 greater than 8 to make -1. 1 more than 8 is 9. Hope this helps! If you are still confused, please comment!

Answer:

4

Step-by-step explanation:

The slope of the green line is the negative reciprocal of that of the red line:

-1 / (-1/4), or just 4

Answer:

+4

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals of one another.

Here, with one slope being -1/4, the slope of a perpendicular line would be +4.

Answer:

2 millimeters

Step-by-step explanation:

Ethan used the scale 1 millimeter : 5 meters.

This means that 1 millimeter in the drawing represents 5 meters in actual life.

The actual  length of the garage is 10 meters. Therefore:

5 meters = 1 millimeter

=> 10 meters = (10 * 1) / 5 = 2 millimeters

The garage is 2 millimeters long in the drawing.

Answer:

A statement that is true about the angle measures of the pieces is that the angle measure of each piece is 72°. This is because there are 360° in a full circle, and if each piece is equal, that means that each piece is a fifth of that. Therefore, the angle measure is 360/5= 72°

Answer:

Step-by-step explanation:

Assuming KH is a straight line with K and H being the beginning and the end of the line. If J is between H and K, it means that J is a point on line HK. Therefore, we can say that

HJ + JK= KH

If HJ = 4x + 9, JK = 3x + 3 and KH = 33, it means that

4x + 9 + 3x + 3 = 33

4x + 3x = 33 - (9 + 3)

7x = 21

Dividing both sides of the equation by 7, it becomes

x = 21/7 = 3

Therefore, HJ = 4 × 3 + 9 = 21

Answer:

112 square inches

Step-by-step explanation:

The surface of the box is formed by 6 rectangles. Two of them have dimensions 7 by 3 inches, two have dimensions 7 by 3 1/2 inches, and two have dimensions 3 by 3 1/2 inches. Finding the area of all of these and adding them together, you get:

[tex]2(7 \cdot 3) + 2(7\cdot 3\frac{1}{2}) + 2(3\cdot 3\frac{1}{2})=[/tex]

[tex]2(21)+2(24\frac{1}{2})+2(10\frac{1}{2})=[/tex]

[tex]42+49+21=112[/tex]

Hope this helps!

Step-by-step explanation:

The age is not a proportional relationship because it does not go through the point (0,0)

The hours is a proportional relationship.  It goes through the point (0,) and has a constant slope

Answer:

3. NO

4. YES

Step-by-step explanation:

A proportional relation is of the form:

y = kx

Note that the y-intercept has to be 0, and slope should be constant

First one (Height against age) is not proportional because the intercept is 30, not 0

Second one (Time against distance) is proportional because the slope is constant and the y-intercept is 0

Answer:

If you divide any number by zero, the answer will be zero.

Step-by-step explanation:

You can't divide by zero. If you divide an number by zero on a calculator, it will come out as 'undefined'.

All other statements are true.

An integer that is positive is greater than zero, and a integer that is negative is less than zero. 0 is equal to 0, so it is neither positive or negative.

The sum of a number and zero will be that number. You are technically adding nothing.

[tex]4+0=4[/tex]

The product of any number and zero is zero. This is the "Multiplication Property of Zero".

[tex]4*0=0[/tex]

"If you divide any number by zero, the answer will be zero." should be the correct answer.

"If you divide any number by zero, the answer will be zero." should be the correct answer.

Addition property of zero:

The addition property of zero says that a number does not change when adding or subtracting zero from that number.

Multiplication property of zero:

The multiplication property of zero says that zero times any number is equal to zero.

Explanation for correct option:

If you divide any number by zero, the answer will be zero.

You can't divide by zero. If you divide an number by zero on a calculator, it will come out as 'undefined'.

All other statements are true.

Explanations for other options:

An integer that is positive is greater than zero, and a integer that is negative is less than zero. 0 is equal to 0, so it is neither positive or negative.

The sum of a number and zero will be the same number. You are technically adding nothing.

The product of any number and zero is zero. This is the "Multiplication Property of Zero".

"If you divide any number by zero, the answer will be zero." should be the correct answer.

Step-by-step explanation:

Question:

Vincent bought a 25-pound bag of rice. He cooked 6.25 pounds of the rice. He stored the rest of the rice in [tex]3\frac{3}{4}[/tex] - pound portions. What is the maximum number of [tex]3\frac{3}{4}[/tex] - pound portions he stored?

Answer:

The maximum number of portion he stored is 5 portion

Step-by-step explanation:

Given

Size of Rice = 25 lb

Size of Cooked Rice = 6.25 lb

Portions saved = [tex]3\frac{3}{4}[/tex] lb

Required

Number of portion saved;

First, the size of rice after cooking needs to be calculated;

If 6.25lb of rice was cooked from a total of 25lb;

Then, the size of rice left is

[tex]Size = 25lb - 6.25lb[/tex]

[tex]Size = 18.75lb[/tex]

Now that we have the amount left after cooking; we can simply calculate the maximum number of portions;

This is calculated by dividing size of rice left by portions of saved rice;

i.e.

Maximum number of portion = Size of rice left / Portions of saved rice

Maximum number of portion = [tex]\frac{18.75lb}{3\frac{3}{4}lb}[/tex]

Convert  [tex]3\frac{3}{4}[/tex] to mixed fraction

Maximum number of portion = [tex]\frac{18.75lb}{\frac{15}{4}lb}[/tex]

Maximum number of portion = [tex]\frac{18.75}{\frac{15}{4}}[/tex]

Rewrite expression

Maximum number of portion = [tex]18.75 / \frac{15}{4}[/tex]

Change divide (/) sign to multiplication (*)

Maximum number of portion = [tex]18.75 * \frac{4}{15}[/tex]

Maximum number of portion = [tex]\frac{75}{15}[/tex]

Maximum number of portion = 5

Hence, the maximum number of portion he stored is 5 portions

Answer:

Probability that 24 or more of those drivers were involved in accidents is 0.15625.

Step-by-step explanation:

We are given that an insurance agent research suggested that first year drivers had roughly an 13% chance of being involved in an automobile accident while driving.

The insurance agent provided insurance to 152 first year drivers last year.

Let [tex]\hat p[/tex] = sample proportion of drivers who were involved in accidents

The z score probability distribution for sample proportion is given by;

                           Z  =  [tex]\frac{\hat p-p}{\sqrt\frac{\hat p(1-\hat p)}{n} {} }[/tex]  ~ N(0,1)

where, p = population proportion of first year drivers involved in an automobile accident while driving = 13%

           n = sample of first year drivers = 152

Now, probability that 24 or more of those drivers were involved in accidents is given by = P([tex]\hat p[/tex] [tex]\geq[/tex] [tex]\frac{24}{152}[/tex])

       P([tex]\hat p[/tex] [tex]\geq[/tex] 0.16) =  P( [tex]\frac{\hat p-p}{\sqrt\frac{\hat p(1-\hat p)}{n} {} }[/tex] [tex]\geq[/tex] [tex]\frac{0.16-0.13}{\sqrt\frac{0.16(1-0.16)}{152} {} }[/tex] ) = P(Z [tex]\geq[/tex] 1.01) = 1 - P(Z < 1.01)

                                                                      = 1 - 0.84375 = 0.15625

The above probability is calculated by looking at the value of x = 1.01 in the z table which has an area of 0.84375.

Hence, the required probability is 0.15625.

Answer:

Talia is not correct. The lateral area has three faces, so the expression should be 3 (one-half (8) (6.9)).

Step-by-step explanation:

A triangular prism has four triangles, three at the sides and one at the base.

A congruent shape has the same feature (side dimensions and angles), therefore all three sides of the prism, and the basal triangle have the same area (since they are congruent).

The area of the base will be One-half (8) (6.9), therefore each of the three sides too will have that same area.

Lateral area means only the areas of the sides excluding the base, therefore, the lateral area will be 3 (one-half (8) (6.9))

Answer:

length = 62.41 inches

Step-by-step explanation:

Using pythagoras theorem -

Let

a = hypotenuse

b = height

c = length

a^2 = b^2 +c^2

75^2 = 41.6^2 + c^2

Therefore,

75^2 - 41.6^2 = c^2

5625 - 1730.56 = c^2

389.44 = c^2

square root (389.44) = c

62.40544848 = c

Answer:

62 inches.

Step-by-step explanation:

and finally, take the square root of the number we are left with after subtracting [tex]B^{2}[/tex] , or 1730.56, from 5625, or [tex]C^{2}[/tex]

5625 - 1730.56 =3894.44
