Answer 1

Area of a triangle is base x height so for the first one you would have to do:
A= 6x14
So area equals
84

Answer 2

Answer:

Triangle:

In order for you to solve all of them you need to multiply the base times the height then divide that in half.

example answer;

3 is 68 because you multiply 17 by 8 then divide in half.

Decomposition of the trapezoid to find the area. You first need to separate the parts of the trapezoid that make a triangles. Ex: separate the outer parts so that you're left with triangle/s and a rectangle/square shape in the middle. Find the area of the triangles and the area of the middle square/rectangle and then add that together.

8. 171 I used this formula A=(a+b)h/2 Which is top length+bottom length times height divided by two.

Trapezoid area:

You need to add the top base and the bottom base together then multiply that by the height.

9. 396. I used the same formula as the last one. which is A=(a+b)h/2.

I hope I could help you :)

Answers

Answer:

Step-by-step explanation:

It can't be A because you aren't using the distributive property. It's not B because using that logic 2+3=4+7 which is not true. It's not c because 3x+7 does not equal 3x+9. So the only logical answer is D.

Answer:

It's A.

Step-by-step explanation:

Its a because 3x+4 and 2+3x+2 are both equivalent. The 2+2 is distributive for 4 in 3x+4. For example, x=2.

3(2)+4 = 10.

2+3(2)+2=10

The chart to the right shows the cost to attend a university for one semester.

Silas will attend the university next year. He has received a $19,000 scholarship and his parents will contribute $16,000 toward his college expenses. If Silas saves for 12 months, about how much will he need to save per month to cover his college expenses for one year (two semesters)?

Select one:

A ] $745.60

B ] $1,250.00

C ] $864.23

A. x = 19
B. x = 23
C. x = 48
D. x = 56

Answers

Answer:

x = 19

Step-by-step explanation:

x + (x + 4) + (3x - 9) = 90°

Combine like terms

5x - 5 = 90

Add 5 on both sides

5x = 95°

Divide 5 on both sides

x = 19

the answer is : x 19

a) they are lighter

b)lighter by 0.0042 pounds

Answer:

A. The label is heavier than the actual weight.

B. The actual weight is 0.0042 less than the labeled weight.

Step-by-step explanation:

I hope I'm correct but here's my explanation.

A. The label said it is 0.384 and the actual weight is 0.3798, which in terms of suggesting the label is just 0.3840 and the actual weight is 0.3798, then the labeled weight would be heavier since it has either rounded up or was guessed.

B. The actual weight is 0.3798 and the labeled weight (assuming after the last decimal number it is zero) would be 0.384. Subtract, and it would be 0.0042.

Though I'm not sure if I'm 100% correct, I do think this might be the most accurate way to solve this.

Hope this helped!

Step-by-step explanation:

Triangle LMN's base length is 15 and triangle XYZ's base length is 6. Since they are both base lenghts, you can just use those numbers in a ratio and simply.

Point A is located at -0.75 and point B 1/4 is located at on a number line.

Part A: Which expression shows how to find the distance between points A and B?

Answers

Answer:

The distance between Points A and B is 1.

Step-by-step explanation:

Given that Point A is located at -0.75 and Point B is located at 1/4 on a number line, to determine which expression shows how to find the distance between points A and B the following calculation must be performed:

1/4 = 0.25

-0.75 + X = 0.25

X = 0.25 - (-0.75)

X = 0.25 + 0.75

X = 1

Therefore, the distance between Points A and B is 1.

Answers

Answer:

Step-by-step explanation:

B) Small triangle:

height = 20 - 15 = 5

base = 1

height to base = 5 :1

Medium triangle :

height = 60 -30 = 30

base = 2

height to base = 30 :2 = 15 :1

Large triangle:

height = 120 - 60 = 60

base = 4

height to base = 60 : 4 = 15 : 1

c) The ratios are same. This is true because wage and working hours are in direct proportion.

E) Take any two points. (1 , 15) & (2 , 30). Find the slope.

Slope = Change in y ÷ change in x

m = (30-15) ÷ (2 -1) = 15/1 = 15

y -y1 = m(x -x1)

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x - 15 + 15

y = 15x

The answer is: Y= 15x

The first one is 1963.5 and the second one is 1357.17

Answer:

V=1357.17 m^3

V=1963.50 in^3

Step-by-step explanation:

first, let's go over the volume formula for a cylinder. it is V=π*r^2*h

the problem says the radius is 6, and the height is 12. we have everything to make the equation!

V=(3.14)(6)^2(12)

V=(3.14)(36)(12)

V=1357.17

let's do the same thing as the first time. the radius is 5. and the height is 25.

V=πr^2h

V=(3.14)(5^2)(25)

V=(3.14)(25)(25)

V=1963.50

Blue bird began at location (6,0) and hit the ground at (26,0). Find the
quadratic equation for his flight path.

Answers

The quadratic equation for his flight path is y = a(x² - 32x + 156) where a is a constant if the Blue bird began at location (6,0) and hit the ground at (26,0).

What is a quadratic equation ?

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

We know the standard form of a quadratic function:

y = ax² + bx + c

Plug x = 6 and y = 0

0 = 36a + 6b + c ...(1)

Plug x = 26, and y = 0

0 = 676a + 26b + c ...(2)

From the equation (1) and equation (2) find the value of b and c

b = -32a

c = 156a

Plug this values in the standard form of a quadratic equation:

y = ax² + (-32a)x + 156a

y = a(x² - 32x + 156)

The above quadratic equation represents the flight path.

Let's take the value of a = -1

y = -1(x² - 32x + 156) (refer attached picture for the path of the graph)

Thus, the quadratic equation for his flight path is y = a(x² - 32x + 156) where a is a constant if the Blue bird began at location (6,0) and hit the ground at (26,0).
