im bad at angles pls help lol

Answer:

C

Step-by-step explanation:

we want to "isolate" h (height). that means "h" needs to be alone on one side of the equation, and all other factors need to be brought to the other side.

so, yes, we need to divide both sides by all factors of h : pi and r². only then will we have the isolated h on one side.

therefore, dividing both sides by pi is a good first step.

the second one

Step-by-step explanation:

Answer:

The correct option is;

D. g(-13) = 20

Step-by-step explanation:

The given information are;

The domain of the function, g is given as -20 ≤ x ≤ 5

The range of the function, g(x), is given as -5 ≤ g(x) ≤ 45

g(0) =-2 and g(-9) = 6

Therefore, given that the function increases from -2, to 6 as the input variable decreases from 0 to -9

Therefore, if the variable, x, decrease further, to -13, the function will likely increase further, to about 20, while in the variable, x, increases further, to 7, the function may likely decrease to about -1

Therefore, we can get either;

g(-13) = 20 or g(7) = -1

However, the domain of the function is -20 ≤ x ≤ 5, therefore, 7 is outside the domain, giving g(-13) = 20 as the only statement that could be true

Answer: -0.1, 0, 0.8, 1.2, 1.6

Step-by-step explanation:

think of numbers on a line with zero in the middle, the numbers would be to the right, positive and inclining, to the left, negative and decreasing, when you throw decimals into the list, you organize them from least to greatest like normal numbers, but the normal numbers are always.

Answer:

B

Step-by-step explanation:

This is because both the denominator and numerator of 3/4 is negative, so the whole fraction is technically negative. Having that symbol ( - ) in front of it also means the whole fraction is negative. It's the same thing.

Answer:

1:8

Step-by-step explanation:

Answer:

1:8

Step-by-step explanation:

Here , 2.5:20

or 25/10:20

or 25:200(Multiplying by 10)

or 1:8(Dividing both sides with 25)

Using the tangent ratio, the size of angle XYZ, to 1 decimal point is: 72.9°

The tangent ratio is given as, tan ∅ = opposite side/adjacent side of a right triangle.

Thus:

Thus:

tan (m∠XYZ) = 13/4

m∠XYZ = tan^-1(13/4)

m∠XYZ = 72.9°

Answer:

(1, -2)

Step-by-step explanation:

midpoint x = (x₁ + x₂) / 2

midpoint y = (y₁ + y₂) / 2

[tex](\frac{-1 + 3}{2} , \frac{2 + -(6)}{2} )[/tex]

  = (1, -2)

The midpoint of the points (-1,2) and (3,-6) is (1, -2).

What is Midpoint?

To find the midpoint of numbers, add two numbers and divide by 2.

Given that;

Two points are (-1,2) and (3,-6).

Now,

Let midpoint of the points (-1,2) and (3,-6) is (x, y)

The value of x = (-1 + 3)/2

                      = 2/2

                      = 1

And, The value of y = (2 + (-6))/2

                              = -4/2

                              = -2.

Thus, The midpoint of the points (-1,2) and (3,-6) is (1, -2).

Answer:

2 1/6

Step-by-step explanation:

How we calculate this is make the two fractions denominators the same so we can make them both 6.

for the 3 we times it by 2 and 2 by 3.

so our 2 fractions are now 2 4/6 and 3/6 Now

so if we take away 3 of 4 we get 1 so 2 and 4/6 is now 2 and 1/6

Meaning the 2 1/6 is what she has left so if she gives that all to her brother he gets that and there's your answer.

[tex]x^{8}[/tex] - 81 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

[tex]x^{8}[/tex] - 81

Step-by-step explanation:

1st question : volume to be filled in liter ?

V cone = 1/3 x base area x h

            = 1/3 x pi x r² x h

            = 1/3 x 3,14 x (30:2)² x 30

            = 1/3 x 3,14 x 15² x 30

V cone = 7,065 cm3 ≈ 7 dm3 ≈ 7 liters

then

we know                         4 liters .............1 minute

we are looking for          7 liters............. n minute

4 x n = 7 x 1

n = 7/4

n = 1,75 min => = 1 min + 0,75x60 = 1 min and 45 sec

Answer:

Step-by-step explanation:

To find equivalent fractions, we multiply the numerator and the denominator by the same number, so we need to multiply the denominator of 7 by a number that will give us 21. Since 3 multiplied by 7 gives us 21, we can find an equivalent fraction by multiplying both the numerator and denominator by 3.Oct 4, 2021
