Hi i have this class work of my cousing
but i need some help beacause i forgot this
the first question is 5_8

Answer:

1,487.3m³

Step-by-step explanation:

Volume of a square based pyramid is expressed as;

V = BH/3

B is the base area

H is the height of the pyramid

Since the side length of the base is 15.3m;

Base area = L²

Base area = 15.3²

Base area = 234.09m²

Height of pyramid = 19.6m²

Get the volume

Volume of the square based pyramid = (234.09*19.6)/3

Volume of the square based pyramid =1,487.3m³ (to the nearest tenth)

Answer:

3x^2 + 13x - 5

Step-by-step explanation:

To find the area, you multiply the length by width. So its is (3x - 1) * (2x + 5)

Then distribute. (3x * 2x) + (3x *5) + (-1 *2x) + (-1 * 5)

So 3x^2 + 15x -2x -5

Final Answer: 3x^2 + 13x - 5

Answer:

Step-by-step explanation:

Supplementary angles have a sum of 180 degrees.

a+a-27.2=180

2a-27.2=180

2a=207.2

a=103.6, and since b=a-27.2

b=76.4

So one angle is 103.6 degrees and the other is 76.4 degrees.

Answer:

(0, 19)

Step-by-step explanation:

Find the equation.

Find the slope:

[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

22-16/1-(-1) = 6/2 = 3

Here's our equation so far:

y = 3x + b

Find b by plugging in one pair of (x,y) coordinates.

22 = 3(1) + b

22 = 3 + b

b = 19

Now we now the equation:

y = 3x + 19

So, the y-intercept is 19.

Answer:

40 ounces

Step-by-step explanation:

Number of ounces per day to be consumed = 4 oz

The number of days = 10

The smallest bag that has enough enough food for the cats is one which has atleast :

Number of ounces consumed per day * number of days

4 oz * 10 = 40 ounces

Answer:

11

Step-by-step explanation:

17+9+11+7 divided by 4

because the mean= sum of the terms divided by the number of terms

the sum= 17+9+11+7=44

the number of terms= 4

44 divided by 4= 11

Answer:

(17+9+11+7) / 4 mean is an average

it is equal to the sum of the elements divided by the number of elements

the sum is 44

the number of elements is 4

the mean is the average= 44/4=11

Step-by-step explanation: i dont know why they would ask that

Answer:

1. BC = 25

2. m∠EDC = 125°

3) BD = 22

4) m∠EBD = 67°

5) FC = 17

6) m∠BEC = 24°

7) CD = 16

8) m∠DBC =  58°

Step-by-step explanation:

The dimensions of parallelogram EBCD are;

EB = 16, ED = 25, BF = 11, EC = 34, m∠BED = 55°, m∠CDB = 67°

1. BC = ED = 25 Opposite sides of a parallelogram are equal

2. m∠BCD = m∠BED = 55 opposite angles of a parallelogram are equal

m∠BCD + mEDC = 180° adjacent sides of a parallelogram are supplementary

m∠EDC = 180° - m∠BCD

∴ m∠EDC = 180° - 55° = 125°

m∠EDC = 125°

3) BD = BF × 2 Diagonals of a parallelogram bisect each other

∴ BD = 11 × 2 = 22

BD = 22

4) m∠EBD = m∠CDB = 67° from alternate angles between parallel lines

5) FC = EC/2 from diagonals of a parallelogram bisect each other

∴ FC = EC/2 = 34/2 = 17

FC = 17

6) m∠BEC = m∠BCE = 24° Alternate angles between parallel lines

m∠BEC = 24°

7) CD = EB = 16 Opposite sides of a parallelogram are equal

8) m∠EBC = m∠EDC = 125° from opposite angles of a parallelogram are equal

m∠DBC + m∠EBD = m∠EBC from angle addition postulate

∴ m∠DBC = m∠EBC - m∠EBD

m∠DBC = 125° - 67° = 58°

m∠DBC =  58°

Answer:

8(h)=x

Step-by-step explanation:

Matt earns 8 dollars for every hour he works. So you multiply the total numbers worked (h) by 8. That will give you the amount of money he's made(x) so the equation would be 8(h)=x

Answer: The answer is Toni can buy 20 tee shirts for 140 dollars

Step-by-step explanation:

First you find out how many times 5 can go into 20

Next you see that 5 can go into 20, 4 times so you take the 35 and multiply 4 and you get 140 so you can buy 20 tee shirts for 140 dollars.

Answer:

Step-by-step explanation:

2 + (3 – 2 x 2) x 1        

This is what I remember, but you need to check this order of arithmetic operations.  

Parentheses first then exponents ( you don't have any) multiplication and division left to right and then addition and subtraction again left to right

2 + (3 – 2 x 2) x 1         so   3 – 2 x 2     equals  3 - 4   which equaltes to  

2 + (-1) x 1                     -1 x 1   =  -1        

2 +  (-1) x 1                     is to clearer to me than  2 + -1 x 1   maybe not

2 +  -1

1                                     it confusing but use your calculator to practice

Step-by-step explanation:

slope is -3/2 and the y intercept is 20

Answer:

If you construct the perpendicular bisector of a line segment, every point on the perpendicular bisector will be the same distance from both point A and point B.

To construct an isosceles triangle, you can start from any point on the perpendicular bisector and draw line segments to point A and to point B

The required steps are in the solution that to use the perpendicular bisector of a segment to draw an isosceles triangle.

An isosceles triangle is defined as a triangle with two sides of equal length.

To use the perpendicular bisector of a segment to draw an isosceles triangle, you can follow these steps:

Draw the segment for which you want to find the perpendicular bisector.

Use a compass to draw a circle with its center at the midpoint of the segment.

With the compass still set to the same radius, draw two arcs that intersect the segment at two points. These points will be the base points of the isosceles triangle.

Draw a line through the midpoint of the segment and the point where the arcs intersect the segment. This line is the perpendicular bisector of the segment.

Use a ruler to draw a line segment connecting the base points of the isosceles triangle.

Use a ruler to draw a line segment connecting the apex of the isosceles triangle (the point where the perpendicular bisector intersects the base) to one of the base points.

At this point, you should have a triangle with two equal sides and a right angle at the apex. This is an isosceles triangle.

Step-by-step explanation:

Other answer choices would not work. y= means you can substitute what y= into the opposite equation for "y."

Answer:

x = 9

Step-by-step explanation:

Because the angles are vertical angles their measures are congruent so make them equal to each other:

3x -8 = 2x +1     subtract 2x from both sides

-2x       -2x

x -8 = 1            add 8 to both sides

 +8    +8

x = 9
