Answer:

  132 units²

Step-by-step explanation:

The figure is a trapezoid, so its area can be found using the formula for the area of a trapezoid.

  A = 1/2(b1 +b2)h

The top "base" is the difference between 21 units and 9 units, so is 12 units. Filling in the numbers, we have ...

  A = 1/2(21 units +12 units)(8 units) = 132 units²

The area of the figure is 132 square units.

Answer:

27°

Step-by-step explanation:

when you see a square to represent that angle, that means that angle is 90 degrees (a right angle)

the angle of a straight line is 180

so [tex]180-90=90[/tex]

[tex]3x+9=90[/tex]

[tex]3x=81[/tex]

[tex]x=27[/tex]

Answer: I would say C

Step-by-step explanation: Its not A cuz 7 is a decimal, its not B because of there being 2 p's and same for D

Answer:

D. p + 0.07p

Step-by-step explanation:

Answer choice D is correct because if we were to plug in a variable (e.g. 1 and 2), we would get the same amount when using 1.07p. All the other answer choices either work for only one value or don't work at all.

For example,

        1 + 0.07 = 1.07

        1.07 = 1.07

       2 + 0.14 = 2.14

       2.14 = 2.14

Answer:

For the first one it would be E.

all i did was make a mental picture and solve after that

for 8:

this is simple. make a circle graph, with radii 6, and plot the points. If they are on the edges of the circle, they are 6 units away from origin. ive attached an image of this lol

Answer:

on the 12th day they will work together

Step-by-step explanation:

george = 3(d ( days))

maria = 4(d)

multiples of 3

1×3 = 3

2×3= 6

3× 3= 9

3×4= 12

3×5=15

3×6=18

3×7=21

3×8= 28

multiples of 4

1×4= 4

2×4=8

3×4=12

4×4=16

5×4=20

6×4=24

7×4=28

8×4=32

The isosceles triangle has 2 equal sides of 4 inches and a vertex angle measure of 70 degrees, and it is a unique triangle

The given parameters are:

Triangle type = Isosceles triangle

Side length = 4 inches

Angle measure = 70 degrees

Since the triangle is an isosceles triangle, then the equal angles would be:

Ф = 180 - 2 * 70

Ф = 40

The length (L) of the third side is:

L/2 = 7 * cos(40)

Multiply both sides by 2

L = 14 * cos(40)

L = 10.7

So, the angles in the triangle are 70 and 40 degrees; while the side lengths are 4 and 10.7 inches

Answer:

hi

Step-by-step explanation:

Answer:

70 degrees

Step-by-step explanation:

2x+3x-20+x+20=180

( angles in a triangle add up to 180 degrees)

as you want to find one x you need to move everything else to the other side: first collect all the like terms: 6x=180

in order to find x you need to divide 180 by 6 which is equal to 30

therefore x=30

if you substitute this into XYZ it would be: 3(30)-20

90-20=70

therefore XYZ=70 degrees

Hope this helped

Answer:

70

Step-by-step explanation:

So we know that the angles of a triangle equal up to 180 degrees. So let's make an equation. So we can do:

2x+(3x-20)+(x+20) = 180

Simplify:

6x=180

x=30

We can also plug this in to check our work. So it would be:

60+(90-20)+(30+20)

simplify

70+50+60=180

Then we have to find angle XYZ so we do 90-20=70

Answer:

StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 12 centimeters over x meters EndFraction

Step-by-step explanation:

The complete question is

Eveline made a scale drawing of a patio she is planning to build.

1 centimeter = 2.5 meters. Triangle A B C. Side A is 12 centimeters, side B is 5 centimeters, and side C is 13 centimeters.

Which proportion could Eveline use to find the length of side A?

StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 13 centimeters over x meters EndFraction

StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 12 centimeters over x meters EndFraction

StartFraction 12 centimeters over 2.5 meters EndFraction = StartFraction x centimeters over 1 meter EndFraction

StartFraction 1 centimeter over 12 meters EndFraction = StartFraction 2.5 centimeters over x meters EndFraction

The picture of the question in the attached figure

we know that

The scale drawing is

That means

1 cm in the drawing represent 2.5 m in the actual

using proportion

Find out the actual length of side A if in the drawing the length is 12 cm

solve for x

The length of side A is 30 meters

The answer is B

Answer:

Yes, they are correct.

Step-by-step explanation:

When reflected across the x-axis, the y coordinate changes. For example, (1, -1) becomes (1, 1). When translated left 5 units, it would be (-4, 1). Since that point is true, that means the shape is in its correct place.
