Need help with a this question thank you

Answer:

Step-by-step explanation:9/5 is the answer

(-5)^2 + (-9)^2 =c^2

25 + 81 = c^2

106= c^2

Sqr rt 106 = c

By using trigonometric relations, we will see that:

cot(θ) = 9/5.

We know that if an angle's terminal side passes through the point (x, y), then we can write the tangent as:

tan(θ) = y/x

In this case, we know that the terminal side passes through (-9, -5), then the tangent is:

tan(θ) = -5/-9 = 5/9

And the cotangent is the inverse of the tangent, then:

cot(θ) = 1/tan(θ) = 9/5.

Answer:

142.4 cubic units is the correct answer

Step-by-step explanation:

right on edge

The volume of oblique cone, to the nearest tenth is,

⇒ 142.3 units³

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

Since, WE know that,

Volume of oblique cone = (1/3) x π x r² x h

Given that,

Radius (r) = 4 units

Height (h) = 8.5 units

Thus:

Volume of oblique cone = (1/3) x π x 4² x 8.5

Volume of oblique cone = 1/3 × 3.14 × 16 × 8.5

Volume of oblique cone = 142.3 units³

Answer:

66°

Step-by-step explanation:

Complementary angles are those that add up to 90 degrees. Since a and b are complementary, we can write:

∠a + ∠b = 90

We already know that ∠a = 24°, so we can plug this in:

24 + ∠b = 90

∠b = 90 - 24 = 66°

Thus, the answer is 66°.

Answer:

C

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Gradient=

[tex] \frac{y1 - y2}{x1 - x2} [/tex]

[tex]m = \frac{ - 12 - ( - 15)}{ - 5 - ( - 1)} \\ m = \frac{15 - 12}{1 - 5} \\ m = - \frac{3}{4} [/tex]

y= -¾x +c

To find c, substitute a coordinate.

When x= -1, y= -15

[tex] - 15 = - \frac{3}{4} ( - 1) + c \\ c = - 15 - \frac{3}{4} \\ c = - 15\frac{3}{4} [/tex]

Thus the equation of the graph is

[tex]y = - \frac{3}{4} x - 15 \frac{3}{4} [/tex]

Therefore the answer is C.

Hello hello!

Solving this is simple, just remember the vertical angles theorem. Due to this theorem, you are able to conclude that x+40 and 60 are equal in terms of their angle measure. This means that to solve this, we need to set both sides equal to each other and solve for x, and plug it in!

STEP ONE: 60 = x + 40

DO: Subtract 40 from both sides.

STEP TWO: 20 = x

DO: You've answered the question!

Answer:

The line equation is y = 1.5x + 3

Fill the first space with '1.5' and the second with '3'

Step-by-step explanation:

The generic model for a line equation is:

y = ax + b

To find the parameters 'a' and 'b', we can use two points of the graph in the equation.

Using the point (0, 3), we have:

3 = 0*a + b

b = 3

Using the point (-2, 0) and the value of b above, we have:

0 = -2*a + b

2a = 3

a = 1.5

So the line equation is y = 1.5x + 3

Answer:

common difference=-3

Answer: B. 140 cubic inches.

Step-by-step explanation:

The question is asking you to find the volume of the rectangular prism.

You can find this by using this formula:

[tex]V = w*h*l[/tex]

Where w is the width, h is the height, and l is the length.

Substitute the sides of the rectangular prism into the equation:

[tex]V = 3.5 * 10 * 4\\\\V = 140[/tex]

The volume of the prism is 140 cubic inches.

The correct answer is B.

Answer:

it is 3 / 10 or  30%

(take 6 / 20 and simplify)

Step-by-step explanation:

Since after I saw that after three different 6 shaded portions left 2 squares i reliezed that it wasn't exactly 33%, so the closest would be 30%.

15 is not a prime factor as it is divided by 1,3,5 and 15.

Additional information:

Prime numbers are those numbers which can only be divided by itself .for instance:1,2,3,5,7 ,11,13 etc.

Step-by-step explanation:

If  The probability of spinning a “1” is 0.25, then the probability of spinning 4 ones is:

0.25*0.25*0.25*0.25 = 0.25^4 ≈ 0.004

(the four events are independent)

The pointer landed on 1 each time, which probability is very low. So, we can conclude that the spinner is not fair.

Step-by-step explanation:

Take away the negative signs:

-80/-20

80/20

Now, divide normally.

80 ÷ 20 = 4

Since a negative number divided by another negative number is positive, the quotient is still 4.

Therefore, the simplified fraction is 4.

Answer:

(0,−7)

Step-by-step explanation:

Since this is the equation of a straight line, there are no restrictions on what you could choose for a value of x. In "official" terms, we say the domain of the function is all real numbers.

Say you pick something simple like x=1. Now, insert this value, and the equation becomes

2−7=y

or y=−5

This means (1,−5) must be a point on the line, and it is also an ordered pair that satisfies the equation.

Answer:

Option B.

Step-by-step explanation:

If the cost of the house (y) is in thousands and area of the house is x ft².

Cost of the house is modeled by the equation given,

y = 0.06x + 60.5

By substituting the values in the line of best fit,

235 = 0.06x + 60.5

0.06x = 235 - 60.5

0.06x = 174.5

x = [tex]\frac{174.5}{0.06}[/tex]

x = 2908.33 ft²

x ≈ 2900 ft²

Therefore, Option B will be the correct answer.

Answer:

Hideki is draining a 45-gallon aquarium at a rate of 15 gallons per minute. Let's solve for the initial value of the linear function that represents thissituation. => 45 gallon aquarium at rate of 15 gallons per minute.

=> 45 gallon / 15 gallon = 3 minutes. Therefore with the rate of 15 gallons per minutes, Hideki will be able to finish the 45 gallon aquarium in 3 minutes.
