Have a great day <3

Answer:

7. 100

8. 56

9. 51

Step-by-step explanation:

Area of triangle: Length × breadth ÷ 2

Area of rectangle/square: Length × breadth

7. Area of shaded region = (20 × 10) - (20 × 10 ÷ 2)

                                          = 100

8. Area of shaded region = (8 × 8) - (4 × 4 ÷ 2)

                                          = 56

9. Area of shaded region = (15 × 5) - (3 × 8)

                                          = 51

Answer:

13+ d = 21

Step-by-step explanation:

sammy already had 13 andellie gave her enough to make her have 21. so 13 plus 8 = 21. so d = 8

Answer:

The expression is not defined in a set of real numbers.

The square root of a negative number is not defined in the set of real numbers.

Answer:

A=300(1+0.035)^t

A=300(1+0.035)^7 = $381.70

A=300(1+0.035)^21 = $617.83

Step-by-step explanation:

It's pretty simple. Use the formula that I posted in the answer. And 1 will always be 1. The decimal comes from the percent. Remember to bring it two places to the left to make a fraction into decimal form. And the t is years. So you raise it to the power of how many years.

Hope this helps

Answer:

none of the lines are parallel or perpendicular to each other

Step-by-step explanation:

which lines are parallel or perpendicular? line A:(-4,-1)(2,-2)line B:(-5,-3)(5,1) line C:(-2,-3)(2,-1)​

in order to know which lines are parallel or perpendicular, we need to find the slopes of the lines given

Slope M  = y2-y1/x2-x1

For line A;

Ma = -2+1/2+4

Ma = -1/6

Slope of line A is -1/6

For line B;

Mb = 1 -(-3)/5-(-5)

Mb = 1+3/5+5

Mb = 4/10

Mb = 2/5

The slope pf line B is 2/5

For line C;

Mc = -1-(-3)/2-(-2)

Mc = -1+3/2+2

Mc = 2/4

Mc = 1/2

Hence the slope of line C is 1/2

Since all the slopes are different , hence none of the lines are parallel or perpendicular

86

Step-by-step explanation:

kahn academy

Answer:

.86 is the Khan Academy Answer

Step-by-step explanation:

1.476 on a z-table makes a .93 z-score. Since 1 - .93 = .7, there is a .7 tail on each side of the distribution. .7 + .7 = .14 and 1 - .14 = .86. Therefore, Emer has a .86 confidence interval.

Answer:

Step-by-step explanation:

Part A

Area of the deck = Area of rectangle A + Area of rectangle B

                            = (12 × 20) + (34 × 8)

                            = 240 + 272

                            = 512 square feet

Part B

∵ 200 square feet of the deck is covered by 1 can of stain

∴ 1 square feet of deck will be covered by the can of stain = [tex]\frac{1}{200}[/tex]

∴ 512 square feet will be covered by the stain = [tex]\frac{512}{200}[/tex]

                                                                             = 2.56

                                                                             ≈ 3

Therefore, 3 cans of stains will cover the entire deck.

8:15 = a:45

Cross multiply:

a × 15 = 8 × 45

15a = 8 × 45

15a = 360

15a ÷ 15 = 360 ÷ 15

a = 360 ÷ 15

Answer:

-2m

Step-by-step explanation:

-6m + 4m

Combine like terms by performing the operation between the coefficients. In this case, one must add the different coefficients, yet since one of the coefficients is negative, then adding the two coefficients is the same as subtracting the two terms.

-6m + 4m

= -2m

The length of LJ is 18 feet.

'An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. This angle measure can be in radians or degrees.'

According to the the given problem,

If we draw a dotted line from H to P and from J to P,

∠HKP = ∠JLP (Similarity of triangles)

HP = JP

KP = LP

⇒ ΔHKP ≅ ΔJLP

⇒ KH = LJ

Now, joining G and P,

GP = HP (radius of the circle)

PM is perpendicular to GH.

⇒ PM equally divides GH .

⇒ KH = GK = [tex]\frac{1}{2}[/tex] of GH

          = [tex]\frac{1}{2}[/tex] × 36

          = 18 feet

Hence, we can conclude that the length of LJ is 18 feet.

-8x + 32 = -8 - 16

32 + 8 + 16 = 8x

4 + 1 + 2 = x

x = 7

Answer:

x=7

Step-by-step explanation:

-8x + 32 = -8 -16

First evaluate -8-16

-8x+32=-24<----

Subtract 32 on both sides

- 8x= - 56<----

divide by 8 on both sides

Answer:

For number 1, the answer is 90°, 55°, and 35°

Step-by-step explanation:

A triangle always equals 180 so you have to subtract the other angles to find the third one. Since you already know that one angle is 35° and the other is 90° you can do 180-90-35 and that equals 55 so those three are your three angle measures

For the show your work part of #1 write:

180°-90°-35°=55°

Answer: Reflection about the y-axis is according to the rule

(x,y)->(-x,y)

Therefore F(x,y) -> F'(-x,y)

The distance between F' and F is (-x,y)-(x,y)=-2x, or the positive distance is 2x.

Answer:

No.  The correct answer is x = 4i.  The mistake is made on the penultimate step where "Mark" squares both sides, eliminating the negative sign.

Step-by-step explanation:

We can see that the answer is incorrect, because if we plug it back into the original equation, we get:

[tex]8 - \sqrt{x} = 10\\8 - \sqrt{4} = 10\\8 - 2 = 10\\6 = 10[/tex]

This of course is obviously incorrect.  The mistake is made in squaring away the negative sign in solving the problem.  An easier way to look at this is to get rid of √x, and substitute it for "n", and see what we get:

[tex]8 - n = 10\\-8 + n = -10\\n = -2[/tex]

If we swap √x back in, we get:

√x = -2

x = 4i

let's solve it correctly:

[tex]8 - \sqrt{x} = 10\\-\sqrt{x} = 10 - 8\\-\sqrt{x} = 2\\\sqrt{x} = -2\\x = 4i[/tex]

Answer:

The answer is A

Step-by-step explanation:

Because if you plug the equation into a calculator you will get -14 and that will be going in the same direction which is this way >
