true or false. can someone help me w this??

Answer: 16m

Step-by-step explanation:

If we're assuming the ratio of height to shadow lenght is the same then

5:4

also equals

20:16

so the tree is 16 m tall

Answer:

Jillian spent $14.49 altogether.

Step-by-step explanation:

Let a = pounds of apples, p = pounds of peanuts, and t = total cost

t = 3.09a + 0.87p

t = 3.09(3) + 0.87(6)

t = 9.27 + 5.22

t = 14.49

Answer:

She can not achieve her average.

Step-by-step explanation:

For her homework average to be 8 or above, she needs to have at least 80 total points to be divided among 10 assignments.

If you add up all the values, 5, 0, 4, 8, 10, 9, 4, 6, 2, you would get 48.

She can not achieve her average because even with the maximum amount of points, 10, 58 is still less than 80.

Answer:

No

Step-by-step explanation:

Most of her scores are under 50 or 50

5 2 4 4 0

Step-by-step explanation:

to make it easier we bring it to the pure y = ax + b form.

y + 1 = 7/8 x

y = 7/8 x - 1

x = -2

y = (7/8 × -2) - 1 = -7/4 - 1 = -7/4 - 4/4 = -11/4

x = 0

y = (7/8 × 0) - 1 = 0 - 1 = -1

x = 1

y = (7/8 × 1) - 1 = 7/8 - 1 = 7/8 - 8/8 = -1/8

x = 8/7

y = (7/8 × 8/7) - 1 = 1 - 1 = 0

x = 2

y = (7/8 × 2) - 1 = 7/4 - 1 = 7/4 - 4/4 = 3/4

Answer:

Answer:

first of all we don't know the exact lift they took but here's your answer:

if they took the plane then that's easy

600×5=3000

105×5=525. 3000-525=2475

while for the bus

3000-60=2940

Answer:

You get negatives

Step-by-step explanation:

Imagine that you have 67 and you need to subtract that by 107

you would do 67-107 or 107-67 then add a negative symbol.

67 - 107 = -40

Answer:

Step-by-step explanation:

[tex]tan \ 83.1 = \frac{opposite \ side}{adjacent \ side} = \frac{BC}{100}\\\\8.2635 = \frac{BC}{100}\\\\8.2635*100=BC\\\\826.35 = BC[/tex]

Height of tower = 826.35 m

Answer:

m = -3/2

Step-by-step explanation:

To find the slope of the representation, use the slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

I'll pick (-4, 9) and (-2, 6) in this instance.

[tex]m=\frac{9-6}{-4-(-2)}\\\\m=-\frac{3}{2}[/tex]

Therefore, the slope of the representation is -3/2.

Answer:

-3/2

Step-by-step explanation:

To find the slope, we can use the formula

m = ( y2-y1)/(x2-x1)

    = ( -6 -9)/(6 - -4)

    = (-6-9)/(6+4)

     -15/10

  -3/2

Answer:

16 ft

Step-by-step explanation:

Slant Height=sqrt(Radius^2+Height^2)

Height=sqrt(20^2-12^2)=sqrt(256)=16 ft

Answer:

3

Step-by-step explanation:

Add up the exponents of the variables

5xyz​ = 1+1+1 = 3

The degree is 3

Answer:

First, just to recap, a  degree of a polynomial is the highest power that it is raised to.

For example, 2x^4 + 3x - 7, is a 4th degree polynomial.

5xyz is a has a degree of 3, since the highest power that it is raised to is to the power of 1, and has 3 terms.

Answer:

A. 29.91

Step-by-step explanation:

tan(x) = opposite leg / adjacent leg

tan(41) = 26 / x

0.869... = 26/x

26 / 0.869... = x

x = 29.91...

Size ...

4 X 3 = 12 size,,

hopes its helps you.

Answer:

please mark me brainlist

Step-by-step explanation:

p = proportion of residents qualified for discounts = 0.70

Sample size = 20

If X is the no of residences selected for discounts then x is binomial with (20,0.7)

P(X>=12) = 0.8867

Answer:

[tex]\boxed{=2x(x^2+6y^2)}[/tex]

Step-by-step explanation:

Remember:

[tex](a+b)(a-b)=a^2-b^2\\\\a^3+b^3=(a+b)(a^2-ab+b^2)\\\\\\(x+2y)^3+(x-2y)^3\\\\=(x+2y+x-2y)((x+2y)^2-(x+2y)(x-2y)+(x-2y)^2)\\\\=2x(x^2+4xy+4y^2-(x^2-4y^2)+x^2-4xy+4y^2)\\\\=2x(x^2+6y^2)\\[/tex]

Answer:

658ft

Step-by-step explanation:

you first have to calculate the angle next to that 28°angle,if you look at the two they form a 90° so to find that angle you have to subtract 90-28=62

the x is the opposite of angle 62 and the 350 si the adjacent so you can use the tan ratio to find the answer

tan62=opposite/adjacent

tan62=y/350

y=tan62×350

=658ft

I hope this helps

Well, it's hard to really help because I can't draw a graph on here, but what you can do is make a list of a couple numbers (say -3, -2, -1, 0, 1, 2, and 3), and then use them as values of x to find y. Once you have found y, use those two values as your coordinate to plot your line:

x = -3, y = -3 + 4 = 1, so the coordinate would be (-3, 1).

x = -2, y = -2 + 4 = 2, so the coordinate would be (-2, 2).

]Hope that helps! Can you do the rest?

Answer:

A= (3,1) ; B=(-2,-1) ; C=(-4,1) ; D=(-4,0)

Step-by-step explanation:

Plotted points are expressed by (x,y) , where the x is equal to the value that you read on the x plot and y is equal to the value that you read on the y plot.
