∠a and ∠b are complementary angles. ∠a measures 24∘. What is the measure of ∠b?

Answers

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°.

im not sure but I think the answer is -4

Answer:

4

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.

If θ is an angle in standard position and its terminal side passes through the point (-9,-5), find the exact value of
cot

θ
cotθ in simplest radical form.

Answers

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.

How to get the cotangent?

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.

Michael made a spinner to use in a game. He tested the spinner by spinning it 4 times. The pointer landed on 1 each time. What do these results suggest about the spinner?

A. It is probably a fair spinner. The probability of spinning a “1” is 0.25.


B. It is probably a fair spinner. The probability of spinning a “1” 4 times is 0.25 × 4, which equals 1.


C. It is probably not a fair spinner. The probability of spinning a “1” on all 4 spins is about 0.004.


D. It is probably not a fair spinner. The probability of spinning a “1” on all 4 spins is less than 0.0001.

Please help

Answers

Answer:

C

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.

A house is listed for sale at $235,000, but the listing does not include square
footage of the house. Based on the comps, the line of best fit is
y=0.06x + 60.5. If the price is fair, what size (in square feet) should the house
be?

A. 2850 ft^2
B. 2900 ft^2
C. 20,000 ft^2
D. 2350 ft^2

Answers

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.

Find an ordered pair (x, y) that is a solution to the equation.
2x-y=7

Answers

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.

Aquarium one contains 4.6 gallons of water. Louise will begin filling aquarium one at a rate of 1.2 gallons per minute.

Aquarium two contains 54.6 gallons of water. Isaac will begin draining aquarium to at a rate of 0.8 gallons per minute.

After how many minutes will both aquariums contain the same amount of water?

Answers

Answer:

25

Step-by-step explanation:

4.6 + 1.2g = 54.6 -.8g

1.2g + .8g = 54.6 - 4.6

2g = 50

g = 25

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.

I am having trouble with this question

Answers

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.

The equation of the line in this graph is y = __x +___.

Answers

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

⇒ 142.3 units³

What is the volume of an object?

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

The angle is equal, set x+40 = 60 solve for x, which is 20

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.
