Answer:

I believe Simon is currently 24 and Tracy is 12

Step-by-step explanation:

24+12=36

12+12=24

you add 12 to each to see in 12 YEARS

Then you can see if it is 1.5 times as much by dividing by 1.5 or multiplying by 1.5

Like:

24*1.5=36

36/1.5=24

And that's how you do it

hope this halps :)

pls mark me brainliest as well

Citrus2011 [14]

If x is the childrens ticket
$4(x + 1.5) + 5x = 33.30 \\ 4x + 6 + 5x = 33.3 \\ 9x = 33.3 - 6 \\ 9x = 27.3 \\ x = \frac{27.3}{6} \\ x = 4.55$
so that means that the adults ticket is
$x + 1.50 = 4.55 + 1.50 = 6.05$

3. Alice took out a simple interest loan to purchase carpet for her house. The interest on the loan

hjlf

Answer:

The price of the carpet was $\$3,697.20$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest Value

P is the Price of the carpet

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=3\ years\\ P=\$?\\ I=\$1,081.43\\r=0.0975$

substitute in the formula above

$1,081.43=P(0.0975*3)$

$1,081.43=P(0.2925)$

Solve for P

$P=1,081.43/(0.2925)$

$P=\$3,697.20$

Answer:

The radius is 6.1 cm

Step-by-step explanation:

The volume of a sphere is

V = 4/3 pi r^3

There is a typo in the problem.

We know the volume

950 = 4/3 (3.14) r^3

Multiply each side by 3/4

3/4 *950 = 3.14 r^3

712.5 = 3.14 r^3

Divide each side by 3.14

712.5/3.14 = r^3

226.910828 = r^3

Take the cube root of each side

226.910828 ^ (1/3) = r^3 ^ 1/3

6.099371323 = r

The radius is 6.1 cm

Find the volume of the rectangular prism: 1\frac{1}{2}\ \textit{inches},\ 2\frac{1}{2}\textit{inches},\ \ 3\ \textit{inches}1 2

loris [4]

Answer:

$\dfrac{45}{4}\ \text{inches}^3\ \text{or }11\dfrac{1}{4}\ \text{inches}^3$

Step-by-step explanation:

Dimensions of prism

$1\dfrac{1}{2}=\dfrac{3}{2}\ \text{inches}$

$2\dfrac{1}{2}=\dfrac{5}{2}\ \text{inches}$

$3\ \text{inches}$

Volume is given by

$V=\dfrac{3}{2}\times \dfrac{5}{2}\times 3=\dfrac{45}{4}\ \text{inches}^3\\ \text{or }11\dfrac{1}{4}\ \text{inches}^3$

The volume of the rectangular prism is $\dfrac{45}{4}\ \text{inches}^3\ \text{or }11\dfrac{1}{4}\ \text{inches}^3$ .
