the ratio of savings to spending money is 5:8
how much does she save and how much does she spend
Answer:
Step-by-step explanation:
first we simplify the ratio
5:8
8/5=1.6
1:1.6 so for every 1 dollar she save she spends 1.6
next we do 1040/1.6=650
1040-650=390
390:650

Answer:
4 pairs of sock and a little bit of left over change.
Step-by-step explanation:
24.95 + 5.95x = 50
-24.95 -24.95
5.95x=25.05
/5.95 /5.95
x = 4.21
We drop the 0.21 because you cant have 0.21 pairs of socks and we get:
x=4
Answer:
About 4 pairs.
Step-by-step explanation:
50.00-24.95=25.05
5.95x5=29.75 (that is more the 25.05, so no.)
5.95x4=23.80 (Its a little bit less but not higher than the number we have left to spend.)

Find the area of a circle in feet with the radius being 3'.
Answer:
28.27 ft²
Step-by-step explanation:
[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius
Plug in 3 for the radius
[tex]A=\pi (3)^2\\A=9\pi[/tex]
[tex]A=28.27[/tex] (approximate answer when rounded to the nearest hundredth)
Therefore, the area of the circle is 28.27 ft².
I hope this helps!
Answer:
exact area: 9 ft²
approximate area: 28.3 ft²
Step-by-step explanation:
An area cannot be in feet. It must be in a square unit such as square feet.
A = r²
A = ()(3 ft)²
A = 9 ft²
A = 9(3.14159) ft^2 = 28.3 ft²
Answer:
exact area: 9 ft²
approximate area: 28.3 ft²

list multiples of a given whole number.
Answer:
The multiples of a whole number are found by taking the product of any counting number and that whole number. For example, to find the multiples of 3, multiply 3 by 1, 3 by 2, 3 by 3, and so on. To find the multiples of 5, multiply 5 by 1, 5 by 2, 5 by 3, and so on.
Step-by-step explanation:
5 × 1 = 5
5 × 2 = 10
5 × 3 = 15
5 × 4 = 20
2 × 1 = 2
2 × 2 = 4
2 × 3 = 6
2 × 4 = 8
2 × 5 = 10 and so on

The length of a ribbon roll is 2.5 m. If 50 cm has been used from it, how much is left?
Answer:
200 cm (or 2 meters) or 80% of the original 250 cm is left. let me know if you have any questions.
Step-by-step explanation:
I'm not sure if that's asking for an exact amount or percent, so I will do both.
The trick either way is to match units. we have meters and centimeters. You could make either one match the other. so 2.5 m is 250 cm and 50 cm is .5 m.
You do have to know how many centimeters is in a meter, but once you know that you can set up unit conversions, which are super simple.
there are 100 cm in a m. a unit conversion is basically a fraction that cancels out units. starting with 2.5 m we want to cancel out m so the fraction we use has the m part in the denominator. so 2.5m * (100 cm)/(1 m). (100 cm)/(1 m) is the unit conversion, and just like variables the m in the denominator cancles out the m in the starting value so it turns into 2.5 * 100 cm/1 = 250 cm.
similarly to go from 50 cm to meters you make the unit conversion have cm in the denominator. so 50 cm * (1 m)/(100 cm) = .5 m. again, the cm int he denominator cancels out the cm in the unit being multiplied. Let me knwo if this is still not clear.
Anyway, now we have the numbers we need. let's make them all cm, I think using the smallest unit is usually easiest. so that's 250 cm total and 50 cm used.
In pure numbers, that means 200 cm is left (which is 2 meters) after 50 cm gets used.
percents is a little trickier. if 250 is 100% then 50 is 20%, which you can get by doing 50/250. if you do not know, a fraction a/b gives you the percent a is of b. Or rather it gives you a decimal, and if you multiply it by 100 it gives you the percent.
anyway, if 20% is used then 80% is left. if you did 200/250 you would get that.

Aria has a points card for a movie theater. She receives 85 rewards points just for signing up. She earns 12.5 points for each visit to the movie theater. She needs 185 points for a free movie ticket. How many visits must Aria make to earn a free movie ticket?
Answer:
8 visits
Step-by-step explanation:
Create an equation, where x is the number of visits to the theater.
Since she gets 12.5 points for each visit, the number of points from visits will be represented by 12.5x.
85 will be added to this, since she gets 85 points for signing up. Then, this will be set equal to 185, since she needs 185 points for the free ticket.
12.5x + 85 = 185
Solve for x:
12.5x = 100
x = 8
So, Aria needs to make 8 visits to earn a free movie ticket
Aria must make 8 visits to earn a free movie ticket when She needs 185 points for a free movie ticket.
By given she has 85 rewards points just for signing up.
She earns 12.5 points for each visit to the movie theater.
She needs 185 points for a free movie ticket.
We must find how many visits does aria has to make to earn a free movie ticket
What is equation?If two expressions with equal sign is called as equation.
Let x is the number of visits to the theater.
Since she gets 12.5 points for each visit, the number of points from visits will be represented by 12.5x.
85 will be added to this, since she gets 85 points for signing up. Then, this will be set equal to 185, since she needs 185 points for the free ticket.
12.5x + 85 = 185
12.5x = 100
x = 8
So, Aria needs to make 8 visits to earn a free movie ticket

4) solve for n, show all work
—6 ( — 2 n + 4 ) = 24
Answer: n = 4
Step-by-step explanation:
-6(-2n + 4) = 24 (divide both sides by -6)
-2n + 4 = -4 (subtract 4 from both sides)
-2n = -8 (divide by -2 on both sides)
n = 4
Answer:
12n - 24 = 24
add 24 to both sides
12n = 48
divide 12 from both sides
n = 4
Solve the linear equation 2(3x + 2) = 2x – 1 + x. State the property that justifies your first step and why you
