The question is an illustration of fraction division and Adam's age as a fraction of Zara's age is 7/5

The ages are given as:

Adam = 3 years and 6 months

Zara = 2 years and 11 months

Rewrite the ages in months

Adam = 3 * 12 + 6 = 42 months

Zara = 2 * 12 + 11 = 35 months

Adam's age as a fraction of Zara's age is calculated using:

Fraction = Adam/Zara

This gives

Fraction = 42/35

Simplify

Fraction = 7/5

Hence, Adam's age as a fraction of Zara's age is 7/5

Answer:

r = 9 meters

Step-by-step explanation:

2r + 8 = 26 <== subtract 8 from both sides

    - 8     - 8

2r = 18 <== divide both sides by 2 to isolate the variable

/2    /2

r = 9 meters

Hope this helps!

Answer:

Step-by-step explanation:

To find the value of r, isolate it on one side of the equation.

[tex]\sf{2r+8=26}[/tex]

First, you have to subtract by 8 from both sides.

[tex]\sf{2r+8-8=26-8}[/tex]

Solve.

Subtract the numbers from left to right.

26-8=18

2r=18

Divide by 2 from both sides.

[tex]\sf{\dfrac{2r}{2}=\dfrac{18}{2} }[/tex]

Solve.

Divide the numbers from left to right.

18/2=9

r=9

Answer:

95th term

Step-by-step explanation:

the nth term of an AP is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 2 and d = a₂ - a₁ = 8 - 2 = 6 , then

[tex]a_{n}[/tex] = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4

the 60th term is then

a₆₀ = 6(60) - 4 = 360 - 4 = 356

so 210 more than a₆₀ = 356 + 210 = 566

now equate [tex]a_{n}[/tex] to 566 and solve for n

6n - 4 = 566 ( add 4 to both sides )

6n = 570 ( divide both sides by 6 )

n = 95

Answer:

95th term.

Step-by-step explanation:

The sequence of 2, 8, 14, 20 . . . can be predicted by adding 6 to each successive term.  This can be written as 6n+2, where n starts at 0 for the first term.

n  Value  (6n+2)

0     2  

1      8

2     14

3     20

4     26

60   362

---

We want to know what term is 210 more than 362.  (362+ 210) = 572

We can solve by using the equation in reverse and solving for n:

(6n+2) = 572

6n = 570

n = 95

The 95th term (572) is greater than the 60th term (362) by 210.

Answer:

Step-by-step explanation:

Remark

If the trinomial is going to factor, it must factor as 5 and 1 paired with 3 and 1 as both 5 and 3 do not factor any further. They are prime numbers.

Let's try this:

(5x  +   1) ( 1x + 3)

Both factors must contain an + otherwise something in the given equation would be - when the factors are expanded.

It looks like this works. 5 * 3x + 1x = 16x

Answer:

D

Step-by-step explanation:

First of all, "k" has nothing to do with determining vertical shrink/stretch, and therefore A and C can be eliminated from the choices. A shrink occurs with a fractional "a" value, so "a" must be greater than 1 in order for a vertical stretch to occur.

Answer:

[tex]12\ gallons[/tex]

Step-by-step explanation:

Step 1:  Determine the unit rate

[tex]Miles / Gallons[/tex]

[tex]162\ miles / 9\ gallons[/tex]

[tex]18\ miles/gallon[/tex]

Step 2:  Determine the amount of gasoline used for 216 miles

[tex]216\ miles * (gallon / 18\ miles)[/tex]

[tex]12\ gallons[/tex]

Answer:  [tex]12\ gallons[/tex]

Answer:

12

Step-by-step explanation:

1. Figure out how many miles the car can go with one gallon of gasolline

162 ÷ 9 = 18

1 gallon = 18 miles

2. Figure out how many times 18 can go into 216

216 ÷ 18 = 12

12 gallons = 216 miles

*We do this because we know that every time the car drives 18 miles its uses another gallon of gas.

The car will use 12 gallons of gasoline to travel 216 miles.

        Volume is solved with L * W * H

        Using these formulas we can see that area uses 2-dimensions, the length and the width, while volume uses 3.

Answer:

Area.

Step-by-step explanation:

2 dimentional spaces have only area, and no volume. Volume describes the amount of space within the container

The percentage shows that they were 28% more likely to come from Riverdale High school.

From the information given, the percentage of those from Rockport will be:

= 25/(25 + 44) × 100.

= 25/69 × 100

= 36.23%

The percentage of those from Riverdale will be:

= 44/(25 + 44) × 100.

= 44/69 × 100

= 63.77%

Therefore, the difference will be:

= 63.77% - 36.23%

= 28% approximately.

Answer:

y = [tex]\frac{1}{2}[/tex] x + 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

f(x) = - 2x + 1 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + c

the line crosses the y- axis at (0, 5 ) ⇒ c = 5

y = [tex]\frac{1}{2}[/tex] x + 5 ← equation of perpendicular line

Substitute 1 for n

a1 = 400 * (1.05)^(1-1)

Evaluate the product

a1 = 400

Substitute 2 for n

a2 = 400 * (1.05)^(2-1)

Evaluate the product

a2 = 420

Substitute 3 for n

a3 = 400 * (1.05)^(3-1)
