Answer:

x = 6

∠2 = 75

Step-by-step explanation:

In the given triangle two sides are equal and so it is an isosceles triangle. So, the angles opposite to equal sides are equal

11x + 9 + 11x + 9 + 30 = 180   {Angle sum property of triangle}

      11x + 11x + 9 +9 +30 = 180

                     22x + 48   = 180

                            22x    = 180 - 48

                               22x = 132

                                   x = 132/22

                                  x = 6

∠2 = 11*6 + 9 = 66 +9 = 75

Answer:

- 0.4 (in decimal)

Step-by-step explanation:

Here "x" is input and "f(x)" is output

Average Rate of Change is = change in output / change in input

At x = 0, the output is 41

At x = 60, the output is 17

= (17-41)/(60-0) = -24/60 = -0.4

Answer:

-9/7 bc the perpendicular is the inverse of the former slope

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Answer:

The answer would be A

Step-by-step explanation:

Use the formula for |A| <= B which is: -B <= A <= B

For this example you would do:

1. Insert the numbers into the formula: -6 <= 2x - 8 <= 6

2. first do the math for -6 <= 2x-8 which is 1 <= x

3. then do the math for 2x - 8 <= 6 which is x <= 7

4. Put that together and you get 1 <= x <= 7

Good luck on the other questions!

Answer:

1. $1.2

2.  $0.14

Step-by-step explanation:

Step one:

given data

Black beans last week that cost $1.34

Step two:

This week's price

5 cans of beans cost $6.00

The cost per can is

= 6/5

=$1.2

The difference in price

=1.34-1.2

= $0.14

Answer:the record low temperature in Alaska = -80°F

Step-by-step explanation:

Step 1

Let the temperature in Alaska be = x

such that  the temperature in Hawaii be -0.15 times temperature in Alaska = -0.15 x.

Step 2

IF the   record low temperature in Hawaii is 12°F.

Alaska = ??

We know that

Hawaii= -0.15 x temperature Alaska ( 0.15 x)

12°F=-0.15 x temperature Alaska(x)

Temperature of Alaska, x =  12°F/-0.15

= -80°F

Answer:

-4

Step-by-step explanation:

Step-by-step explanation:

To figure out this answer, you need to figure out how much 9% is in $64.00

  ?              9

-------   =   --------  

 64           100

Now to solve this you have to multiply diagonally and divide the neighbor

(let me explain)

basically in this case, you would multiply 64 and 9, then divide by 100

64 * 9 = 576

576 / 100 = $5.76

In short: your answer is 'A' $5.76

Answer:

y = -1/2 x

Step-by-step explanation:

slope = Δy / Δx

= 4 - 1 / -8 - (-2)

= 3 / -6

m = - 1/2

y = mx + b

1 = (-1/2)(-2) + b

1 = 1 + b

b = 0

eqn of the line : y = -1/2 x

Answer:

2x+8y=6

Step 1: Add -8y to both sides.

2x+8y+−8y=6+−8y

2x=−8y+6

Step 2: Divide both sides by 2

[tex]\frac{2x}{2}[/tex] = [tex]\frac{-8y+6}{2}[/tex]

x=−4y+3

Answer:

X=18, Y=6

Step by Step Explanation:

This is a little long winded.. Let's solve for Y first.

First looking at the problem, you can note a few things. First of all, there is an Isosceles triangle, and there is an equilateral triangle. Where they connect, there is a 90° angle.

Now, all equilateral triangles have the same angle measurement. 60°. Now, if you look where the right angle is, it is showing a 60° angle, a total of 90°, and an unknown area. So simply subtract. 90-60=30. Divide that by 5, and you have your answer of 6.

Now let's solve X. X is very simple. On an isosceles triangle, the two top sides are the same length. And one of the top sides is the same size as the equilateral triangle. And on equilateral triangles, all sides are the same.

So the 11 transfers over to the X side. So let's make a small equation. 11=X-7. To make it even, let's add 7 to both sides. 11+7=X+7-7. Simplify to get 18=X, which is your answer.

Answer:

X=18 y=6

Step-by-step explanation:

Given:

The height of an object, f(x), after x seconds is

[tex]f(x)=-2x^2+32[/tex]

To find:

The time taken be object to hit the ground.

Solution:

We have,

[tex]f(x)=-2x^2+32[/tex]

The object will hit the ground if the height is 0, i.e., f(x)=0.

[tex]0=-2x^2+32[/tex]

[tex]2x^2=32[/tex]

Divide both sides by 2.

[tex]x^2=\dfrac{32}{2}[/tex]

[tex]x^2=16[/tex]

Taking square root on both sides.

[tex]x=\pm 4[/tex]

Time cannot be negative. So, x=4.

Therefore, the object will hit the ground after 4 seconds.

Answer:

$32

Step-by-step explanation:

Since the question says that all the apples were sold for a total of $160, this means that you have to add the additional basket of the friend's to Olivia's. Since Olivia has 4 baskets of apples and her friend has 1, 4+1=5. Since you're trying to find the unit price for 1 basket, you take the total of $160 and divide it by 5 to find how much each basket of apples costed. Since 160/5 is 32, $32 is your answer.
