2 x 7(billy's age) = 14
^2 times billy's age

14 + 3 = Jane's age
^3 years older(added) than 2 times billy's age

17 = Jane's age

hope this helps and have a great day :)

J(Jane) + 3 = B(Billy)*2
J + 3 = 7(2)
J + 3 = 14
J = 14-3
J = 11 (Jane is 11)Cheers!

Tommy earned $76.00 in interest after 5 years on a principal of $400. Jane earned $82.00 in interest after 2 years on a principa

vovikov84 [41]

Answer:

The bank in which Jane has invested.

Step-by-step explanation:

For Tommy's Bank:

P = $400

t = 5 years

I = $76

Simple interest formula is given by

$I=Prt\\\\76=400(r)5\\\\r=0.038\\\\r=3.8\%$

For Jane's Bank:

P = $1000

t = 2 years

I = $82

Simple interest formula is given by

$I=Prt\\\\82=1000(r)2\\\\r=0.041\\\\r=4.1\%$

Since, Jane's bank has higher interest rate. It means one can get higher interest if invest in this bank.

Therefore, we should prefer the bank in which Jane has invested.

Question # 4

Sedbober [7]

Answer:

Brett is 62 years old, Carl is 70 years old and Mark is 80 years old.

Step-by-step explanation:

let the age of Brett be x years.

thus the age of Mark is (x+18) years .

{as it is given that Brett is 18 years younger than Mark}

∴ Age of Carl is (x+8) years .

Now the sum of ages,

3x+26=212 (given)

3x=186

∴x=62

thus , the age of Brett is 62 years , the age of mark is (x+18)= 80 years and the age of Carl is (x+8)= 70 years

By definition of surface area and the area formulae for squares and rectangles, the surface area of the composite figure is equal to 166 square centimeters.

<h3>What is the surface area of a composite figure formed by two right prisms?</h3>

According to the image, we have a composite figure formed by two right prisms. The surface area of this figure is the sum of the areas of its faces, represented by squares and rectangles:

A = 2 · (4 cm) · (5 cm) + 2 · (2 cm) · (4 cm) + (2 cm) · (5 cm) + (3 cm) · (5 cm) + (5 cm)² + 4 · (3 cm) · (5 cm)

A = 166 cm²
