Step-by-step explanation:
While shopping, Kyla found a dress that she would like to purchase, but it costs $49.50 more than she has. Kyla charges $5.50 an hour for babysitting. She wants to figure out how many hours she must babysit to earn $49.50 to buy the dress.
Answer:
9 hours
Step-by-step explanation:
We can do this 2 ways but I think you will want this the easiest way :)
So we can divide:
49.50/5.50
9
Or we can multiply and keep multiplying 5.50 by different numbers until we get 49.50 or over (this way will take longer)
5.50 x 1
5.50 x 2
and so on and so fourth
With the first way we figued out she will need to babysit for 9 hours :)
Have an amazing day!!

Tormod bought a perfectly square table but found out it won't fit through his study
door. To solve the problem, he reduces its width by 9cm but also extends its length by
9cm. Its new area is 309cm?
What was the area of his original square table?
Answer:
390 cm^2
Step-by-step explanation:
Let's call the dimensions of the original square x by x. Its area is x^2.
After the table is altered, its dimensions are x + 9 by x - 9, and you're given the area is 309 cm^2.
[tex](x+9)(x-9)=309\\\\x^2-81=309\\\\x^2=390[/tex]
This last equation is telling us the area of the original, square table.

if diameter of a bagel is 4.2inches what is radius in inches
Answer:
Radius: 2.1Inches
Step-by-step explanation:
Circumference
Circumference is the linear distance around the circle edge.
Radius
The radius of a circle is any of the line segments from its center to its perimeter. The radius is half the diameter or r = d

.
Diameter
The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter is twice the radius or d = 2·r.
The Greek letter π
π represents the number Pi which is defined as the ratio of the circumference of a circle to its diameter or π = C
d

11. If the perimeter of the given triangle is more than 22 cm and less than or equal to 30cm. express it in inequality and solve it.
Answer:
5 < x ≤ 7
Step-by-step explanation:
perimeter = 2x + x + x + 2 = 4x + 2
perimeter is more than 22 so 22 is less than perimeter , then
22 < 4x + 2 ≤ 30 ( subtract 2 from each interval )
20 < 4x ≤ 28 ( divide each interval by 4 )
5 < x ≤ 7

Answer:
$1322.67
Step-by-step explanation:
Let the total amount that Sarah deposited be $x
using the annuity formula:
A=P[((1+r)^n-1)/r]
A=future value
r=rate
n=number of years
from the information given:
A=$500000
r=2.75%
n=65-42=23 years
p=$x
thus plugging our values in the formula we get:
500000=x[((1+0.0275)^(23)-1)/(0.0275)]
500000=31.50x
x=15,872.04883
She deposited 15,873.04883 per year
The monthly deposit will therefore be:
15873.04883/12=$1322.67

At Thomas High School, 200 students go to school by their own vehicle. If this number of students is 40% of school enrollment, then how many students are there in the school altogether?
Answer:
500 students
Step-by-step explanation:
40% = 200 students
divide both by 4 to 10%
10% = 50
multiply both by 10 to get 100%
100% = 500
or the quicker way,
200 x 2 = 400 (80%) + 100 (20%) = 500 (100%)

Find the value of x.
Answer:
41
Step-by-step explanation:
76, x and 63 are linear pair angles.
Sum of linear pair angles is 180,
76 + x + 63 = 180
x + 76 + 63 = 180
x + 139 = 180
x = 180 - 139
x = 42

Answer:
- 200
Step-by-step explanation:
377 is lesser than 577.
Here,
577 is the Greater number.
377 is the Smaller number.
When Smaller number is subtracted from Greater number, the result will be ( - ).
So,
377 - 577 = - 200

You helped 3.6 customers per half hour yesterday so I helped how many customers in 7,.5 hours yesterday
Step-by-step explanation:
I guess, "you" and "I" are working with the same efficiency and work rate.
and with the typos in it, it is not clear, if I understood the problem and the given data properly.
but based on what I understood :
so, 3.6 customers in 0.5 hours.
7.5 hours × 2 = 15 times 0.5 hours.
15 × 3.6 = 54 customers.
so, with the same work rate as you, I helped 54 customers in 7.5 hours.
