Hanna's dad is designing a new rectangular garden for his backyard. He has a 20ft fence to put around the garden. He wants the length of the garden to be 2 1/2 longer than its width. What must the width of the garden be?
Answer:
3 3/4 feet
Step-by-step explanation:
Given
Perimeter of the garden = 20ft
If he wants the length of the garden to be 2 1/2 longer than its width, then;
L = 2 1/2 + W
L is the length
W is the width
Perimeter of the garden = 2(L+W)
P20 = 2(5/2 + W+W)
20 = 5 + 2W+2W
20 - 5 = 4W
15 = 4W
W = 15/4
W = 3 3/4 ft
Hence the width of the garden is 3 3/4 feet

Write the phrase as an expression.
a number t cubed
An expression is
Answer:
t to the 2 power
Step-by-step explanation:
The expression for a number t cubed is t³.
What is Expression?A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of expressions. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the expression x/2 + 6.
As an illustration, the phrase x + y is one where x and y are terms with an addition operator in between.
Given statement:
a number t cubed
Here the number be t.
So, the number t is cubed which can be written as
= t³
Hence, the expression is t³.

Help my little cousin, shes only 10 yrs old!

Miah is 4 years old. Sophia is 3 times the age as Miah! Clara is 2 times the age as Sophia. How old is Sophia and Clara?
Answer:
Sophia is 12 Clara is 24
Step-by-step explanation:
If Sophia is 3 times the age of Miah, we can multiply Miah's age (4) by 3 to find out how old she is. 4 x 3 = 12.
We can kind of do the same thing to find Clara's age except we are multiplying 12 by 2. 12 x 2 = 24

You go to the Footlocker to purchase a pair of Jordans, the price for them is $240.00. The sales tax is 7.5%. How much will you have to pay for them? $240.00 times 7.5%
Answer:
258
Step-by-step explanation:
[tex]\frac{a}{w}[/tex]=[tex]\frac{p}{100}[/tex]
[tex]\frac{a}{240}[/tex]=[tex]\frac{0.075}{100}[/tex]
240x0.075=100a
=0.018x100
=18+240

Samir goes to a farmers market to buy some fruit. He fills a large bag with 24kg of apples. He realises that he cannot carry this weight,so puts some of the apples into a smaller bag. The weight of the apples in the large bag is 6kg larger than the smaller bag. What is the weight of the smaller bag
Answer:
9 kg
Step-by-step explanation:
The total weight is 24 kg. The difference between the large bag and the small bag is 6 kg. 15 + 9 = 24. 15 - 9 = 6. Therefore, the smaller bag weighs 9 kg.
