One number is 7 more than 4 times another number if the sum of the numbers is 22 find the numbers
Answer:
3 and 19
Step-by-step explanation:
The smaller number is x. The bigger number is 4x + 7. Big number + small number= 22. x + 4x + 7 = 22. 5x= 15. x= 3.
Small number= x= 3
Big number= 4x+7= 12 + 7 = 19
In a poll of 300 preschoolers, 125 said they preferred chocolate ice cream, 71 said they preferred vanilla, 100 said they preferred cookies & cream, and 4 said they had never eaten ice cream. If a pie chart were to be made showing the preference for each flavor, the central angle for the chocolate ice cream sector would be:_________
Find the percentage of the people who like Chocolate = chocolate/ total x 100
Percentage = 125/300 = 0.41666 x 100 = 41.6667 = 41.67 ( round as needed)
A full circle is 360 degrees.
The central angle = percentage of chocolate x 360:
0.416666 x 360 = 150
The central angle for chocolate is 150 degrees

Find the value of x in each of the following
(please do it step by step and don't spam)
Answer:
x=120 and x=110 because adjacent angle
Answer:
D= 60 degrees(corresponding angles) Q = 70 degrees (interior angles)
Step-by-step explanation:
For the first one you can find G right away cause they are corresponding angles you know this cause they form an f shape and then after you find G you can find D cause they are corresponding
For the second one you can find V right away cause V and S are corresponding after you find V which is 110 you do interior angles ( Q and V are in a U shape and angles in that shape add upto 180 and are called interior angles) So Since V is 110 , you have to minus 110 degrees from 180 degrees and so Q is equals to 70 degrees

To pay for a 15,300 car, Tony made a down payment of $3900 and took out a loan for the rest. On the loan , he paid monthly payment payment of $252.34 for 4 years.
Answer:
a. $24,512.32
b. $712.32
Step-by-step explanation:
a. A price of car $15,300, Tony made a down payment of $3900 so car has $11,400 left of a price and took out a loan.
He paid monthly payments of $252.34 for 4 years. Which mean $252.34 is paid for 48 months, multiplication $252.34 and 48 are $12,112.32. So we have monthly payments is $12,112.32
The total amount Tony ended up for the car is $11,400 + $12,112.32 = $24,512.32
b. The interest Tony pay on the loan is $12,112.32 - $11,400 = $712.32

their heights together.
They
got a total of 15 feet 3 inches.
Convert that measurement to
inches.
Answer:
183 inches.
Step-by-step explanation:
There are 12 inches in a foot.
12 * 15 = 180
Plus the 3 spare inches.
180 + 3 = 183
Answer:
Step-by-step explanation:
There are 12 inches in a foot.
The height in inches is 12 * 15 = 180
Total height = 12 * 15 + 3
Total height = 180 + 3
Total height = 183 inches

Answer:
can u please cut all zeroes and if it is divisible by both a and b then divide it.Like in a u cut zeroes and answer will come. cut all zeroes only.
Hi, if the question is reduce to lowest terms, then this is the answer.
a) 1/2
b) 1/4
c) 2/3
d) 2/5
g) 4/5
h) 4/7
i) 5/6
j) 6/7
How did this come?
In these questions, all are ending with 0. So, if you cut those zeroes, you will get a fraction, then check if can divide the fraction directly, else, write the fraction which you got directly after cancelling zero.
Hope it helps you...

Anna would like to purchase a new bike that costs $205. She already has $31 saved. If she saves a maximum of $12 a week, the following inequality can be used to find the minimum number of weeks, w, it will take Anna to save the money to purchase the bike.
12w+31 ≥ 205
Please show all steps thank you
Answer:
It will take at least 15 weeks
Step-by-step explanation:
12w+31 ≥ 205
Subtract 31 from each side
12w+31-31 ≥ 205-31
12w ≥ 174
Divide each side by 12
12w/12 ≥ 174/12
w ≥ 14.5
Rounding up to the nearest integer
w ≥ 15
It will take at least 15 weeks

43. Find the equation of a line perpendicular to the y-axis passing through the point (4, 7).
9514 1404 393
Answer:
y = 7
Step-by-step explanation:
The y-axis is the vertical line x=0. A perpendicular line will be a horizontal line that will have an equation of the form ...
y = constant
In order for that line to go through a point with y-coordinate 7, the line must be ...
y = 7
14. Solve y2 + 4y - 32 = 0 using the zero product property.
O A. y = 8,4
O B. y = -8,4
O c. y = -8,6
O D. y = 3
Answer: B. y = -8, 4
Step-by-step explanation:
Given expression
y² + 4y - 32 = 0
Cross factorize the expression
y 8
y -4
Factorize the expression
(y + 8) (y - 4) = 0
Finalize the factor of the expression by the zero product property
[tex]\boxed{y=-8,4}[/tex]

A washer and a dryer cost $930 combined. The washer costs $ 80 more than the dryer. What is the cost of the dryer?
Answer:
$505
Step-by-step explanation:
930 - 80 = 850
850 / 2 = 425 (price of the washer)
425 + 80 = 505 (price of the dryer)
Answer:
the dryer costs $425
Step-by-step explanation:
x = washer
y = dryer
x + y = 930
x = y + 80
using the second equation as substitute in the first equation we get
y + 80 + y = 930
2y = 850
y = $425
FYI
x = y + 80 = 425 + 80 = $505

Answer:
(a) z(105)= (105-95)/10
= 1
z(85)= (85-95)/10
= -1
P(85< x < 105) = P(-1< z < 1) = 0.6825
Quantity of people of 1600 that have IQ between 85 and 115 = 0.6825*1600= 1092
(b) z(105) = (115-95)/10 = 2
z(85) = (75-95)/10 = -2
P(-2< z < 2) = 0.6827
quantity of people of 1600 that have IQ between 75 and 115 = 0.6825x1600=1092
(c) Z(>125)=( 125-100)/10=3

Is Canada‘s population is 1/10 of the United States and Canada‘s population is 32 million how many people live in the United States
Answer:
320M
Step-by-step explanation:
It is given that Canada's population is 1/10th of the USA's population, essentially meaning that the US's population is 10x that of Canada's. Therefore, if Canada's population is 32M, multiply 10 to that:
32,000,000 x 10 = 320,000,000
320,000,000 people live in the US.
