Size of angle x in 51

Step-by-step explanation:

(x - 4)(x - 1)

= x² - x - 4x + 4

= x² - 5x + 4.

Answer:

[tex]\huge(x - 4)(x - 1) \\ \huge= {x}^{2} - x - 4x + 4 \\ \huge = {x}^{2} - 5x + 4[/tex]

Answer: Write the equation with the "formula" with whatever you do have.

Volume = area of base times height.

V = πr²h

Step-by-step explanation: Sometimes they just want to see what you do with the information you have. Sometimes there is a hidden clue, like a puzzle.

Answer:

Step-by-step explanation:

You make 4 into 4/1 and then raise it to 8/2. then you divide across, if im right.

Answer:

4 is the same things as 4/1. and we know that dividing by a fraction is the same thing as multiplying by its reciprocal. so 5/2 times 1/4. just multiply straight across and you get 5/8

Step-by-step explanation:

Answer:

The angles are complementary angles

Step-by-step explanation:

Given that a triangle has three sides and three angles

From the above question the unknown side of the triangle has a fixed value ( given ) hence the two angles adjacent to the unknown side will be complementary angles. this is because the sum of the angles of a triangle = 180°

Answer:

Because the given conditions (7 centimeters, 9 centimeters, and 74°) are fixed and the unknown side length is fixed, the angles adjacent to the unknown side must also be fixed.

Step-by-step explanation:

Answer: 4 seconds

Step-by-step explanation:

Given: The function [tex]h(t)=-36t^2+288t+9[/tex] can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.

Differentiate the given function with respect to t , we get

[tex]h'(t)=-36(2)t+288=-72t+288[/tex]

Put h'(t)=0

[tex]\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4[/tex]

Also, [tex]h''(t)=-72<0[/tex]

By second derivative test, h(t) is maximum at t=4.

Hence, the time in Devon which the ball reaches it maximum height = 4 seconds

15 boxes x 12 strawberries = 180 strawberries

180 - 162 = 18 strawberries

He still need more 18 strawberries

Answer:

The correct answer is "rational" . It is not an "integer" because it is a "decimal value". It is not "irrational" because the decimal value terminates and does not repeat.

Answer:

We conclude that there is NOT a proportional relationship between the distance the blimp travels and the time it travels.

Step-by-step explanation:

We know if y varies directly with x, we get the equation

y ∝ x

y = kx

k = y/x

where k is called the constant of variation.

In our case we are given:

A blimp travels 255 feet in 1/2 minute

here:

y = 255, and x = 1/2 = 0.5

so substituting y = 255 and x = 0.5 in the equation

k = y/x

k = 255 / 0.5

k = 510

A blimp travels 510 feet in 1/6 minute

here:

y = 510 , and x = 1/6

so substituting y = 510 and x = 1/6 in the equation

k = y/x

k = [510] / [1/6]

k = 3060

A blimp travels 3,060 feet in 1 minute

here

y = 3,060, and x = 1

so substituting y = 3,060 and x = 1 in the equation

k = y/x

k = 3,060 / 1

k = 3060

HERE IS THE VARIATION OF THE CONSTANT OF VARIATION:

A blimp travels 255 feet in 1/2 minute

k = 510

A blimp travels 255 feet in 1/2 minute

k = 3060

A blimp travels 3,060 feet in 1 minute

k = 3060

It is clear that the constant of variation does not remain constant.

Therefore, we conclude that there is NOT a proportional relationship between the distance the blimp travels and the time it travels.

Answer: 3 Miles

54 / 4 = He's going one mile every 14 minutes. Use unit rates i.e 1 mile for every 14 minutes to figure out that he would skate 3 miles in 42 minutes.

Answer:

3 miles

Step-by-step explanation:

The problem above is related to the topic on "Equivalent Ratios." In order to find the missing term in a proportion, you can use cross products.

Let n be the "missing term" or the number of miles that Bart Simpson can skateboard in 42 minutes.

Therefore, it takes 3 miles for Bart Simpson to skateboard in 42 minutes.
