39 inches tall at equal height after 5 years

Step-by-step explanation:

Tree A at 5 years

2x5+29=39 inches

Tree B at 5 years

5x5+14=39 inches

Answer:

★ The answer for A= 2t + 19

★ The answer for B= 5t + 14

★ So the answer would 39 inches tall which would be equal to a height after 5 years

Answer:

True

Step-by-step explanation:

Cuz if u substitute (3,-3/2) it would work

Y = 1/2x - 3

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

-3/2 = 1.5 - 3

-3/2 = -1.5

& -3/2 is -1.5 as a decimal lol

Answer:

ST=8.8

SR=15.5

Step-by-step explanation:

ST is the difference between S and T.

that would be 16.3-7.5=8.8

similarly RT is the difference between S and R

That would be 7.5-(-8)=15.5.

Answer:

ST = 8.8

SR = 15.5

Step-by-step explanation:

As the question demonstrates, they're looking for the measure of ST - which means the distance from S to T.

Now to get ST you'll have to subtract the values given on the number line.

T = 16.3

S = 7.5

16.3 - 7.5 = 8.8

ST = 8.8

Moving on with SR, we have the following. We use the same method of differentiation.

S = 7.5

R = -8

7.5 - (-8) = 15.5

SR = 15.5

1) m=7

Answer:

3:8

Step-by-step explanation:

The ratio of Mina's age to Naomi's age is 3 : 4

Multiplying the above ratio by 2 = 6:8

The ratio of Lev's age to Mina's age is 1 : 2

Multiplying the above ratio by 3

= 3:6

Therefore, ratio of Lev's age to Naomi's age in simplest form.

= 3:8

Answer:

3:8

Step-by-step explanation:

Let L, M, and N stand for the three ages.

The given ratios tell us that

M = 2L

and

N = 4/3M.

Therefore,

N = 4/3 x 2L = 8/3L.

This means that Lev's and Naomi's ages are in the ratio 3:8.

Answer:

y = 3/4 + b

Step-by-step explanation:

To get slope intercept form you need to have the y = then you need to find the slope which is y2 - y1 and x2 - x1, find the answer whether it be a fraction or a whole number. And since you don't know the y-intercept you mark the last integer as b, since you don't the answer. So it comes out to y = 3/4 + b

y = (3/4)x + 5

Using the two coordinates, you can find slope and y-intercept

y-intercept is 5, from the point (0,5)

slope is 3/4, from rise/run, and that 0 to 4 is 4, while 5 to 8 is 3.

Combine slope and y-intercept for slope intercept form

y = (3/4)x + 5

Answer:

5390 gallons of water was wasted by the city's residents last year.

Step-by-step explanation:

Let [tex]x[/tex] denotes gallons of water wasted by the city's residents last year.

Gallons of water wasted by the city's residents this year = 2695 gallons

This is 50% less than last year.

Therefore,

[tex]x-\frac{50}{100}x=2695\\\\\frac{50}{100}x=2695\\\\\frac{x}{2} =2695\\\\x=2(2695)[/tex]

[tex]x=5390[/tex] gallons

So, 5390 gallons of water was wasted by the city's residents last year.

The answer is : $36.36

Step-by-step explanation:

The given box is a rectangular box. To find the felt needed to cover the box, we need to find the surface area of the rectangular prism.

Surface area of a rectangular prism = 2(l*w + w*h + h*l), where "l" is the length, "w" is the width and "h" is the height of the rectangular prism.

Given: l = 11 inches; w = 8 inches; and h = 6 inches.

Now plug in these given values in the above formula, we get

Surface area of the rectangular prism = 2 (11* 8 + 8*6 + 6*11)

= 2(88 + 48 + 66)

= 2(202)

= 404

The surface area of the rectangular prism = 404  square inches.

The felt cost 9 cents square inches.

Convert 9 cents to dollar.

9 cents = $0.09

To find the cost of the felt needed to cover prism multiply 404 by 0.09

The total cost = 404*0.09 = $36.36

Hope this helped :)))

Answer:

the numbers are 41 and 23

Step-by-step explanation:

Given data

let the numbers be x and y

x+y/2= 55

cross multiply

x+y= 110----------1

positive difference is 64

x-y= 64-----------2

solve 1 and 2

x+y= 110

x-y= 64

from 1

x= 110-y

put the value of x in 2

110-y-y=64

110-2y=64

110-64=2y

46=2y

y= 46/2

y=23

put y= 23 in 2

x-23= 64

x= 64-23

x=41

Answer:

(a) [tex]j = 4k[/tex]

(b) [tex]4k - 18 = 18 + k[/tex]

(c) Jim initially had 48; Kirk initially had 12

Step-by-step explanation:

Given

[tex]j = Jim[/tex]

[tex]k=Krik[/tex]

Solving (a): An equation for the amount they originally had.

From the question, we understand that j is 4 times as many as k.

Mathematically, this is:

[tex]j = 4 * k[/tex]

[tex]j = 4k[/tex]

Solving (b): Equation after Kirk wins

Initially Kirk had k.

To get the new expression, we add 18 to k.

This gives: 18 + k

In the same vein, Jim's number of chirps will reduce by 18.

Initially, Jim had j chirps (or 4k chirps)

To get the new expression, we subtract 18 from j.

This gives: j - 18

So, the equation is:

[tex]j - 18 = 18 +k[/tex]

Solving (c): Number of chirps they started with.

In (b), we have:

[tex]j - 18 = 18 +k[/tex]

Substitute 4k for j

[tex]4k - 18 = 18 + k[/tex]

Collect Like Terms

[tex]4k - k = 18 + 18[/tex]

[tex]3k = 36[/tex]

Divide both sides by 3

[tex]k =12[/tex]

Substitute 12 for k in [tex]j = 4k[/tex]

[tex]j = 4 * 12[/tex]

[tex]j = 48[/tex]

Answer:

b ≈ 25.6

Step-by-step explanation:

From the figure attached,

By applying tangent rule in the given triangle,

tan(32°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(32°) = [tex]\frac{16}{b}[/tex]

b = [tex]\frac{16}{\text{tan}(32)}[/tex]

b = [tex]\frac{16}{0.62487}[/tex]

b = 25.605

b ≈ 25.6

Answer:

Step-by-step explanation:

The diagonals are equal length:

[tex]6x - 14 = 8x - 20\\-2x = -6\\x = 3[/tex]

[tex]BD = 6x - 14\\BD = 6 * 3 - 14\\BD = 18 - 14\\BD = 4[/tex]

The length of diagonal BD in rectangle ABCD is 4 units.

A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are parallel and equal to each other. All the angles of a rectangle measure 90 degrees.

The diagonals of a rectangle are equal to each other.

AC = BD (diagonals of rectangle are equal)

6x - 14 = 8x - 20

2x = 6

x = 3

BD = 6(3) - 14 = 4 units

The length of diagonal BD in rectangle ABCD is 4 units.

Hi there! x would be 6 weeks..

Explanation:

So here says that Jana earns $25 per week for mowing the lawn. But in “x” weeks, she earns $125...this means that you would have to divide 125 with 25 or 25 multiply by x to find the answer of x.

How much does 25 go to 100? Well it would be 5. So for $100 it would be 5 weeks. We also know that 25 is 1 week. So add 5 with 1. 5 plus 1 would be 6.

Therefore, for $125, Jana would have to work for 6 whole weeks.
