Answer:
87
Step-by-step explanation:
9 2/3 = 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 6/9 = 87/9
Answer: 87 ninths
Step-by-step explanation:
See how many 1/9ths fit inside 9 2/3 using division
[tex]9\:\frac{2}{3}\div \frac{1}{9}[/tex] or
[tex]\frac{29}{3}\div \frac{1}{9}[/tex]
[tex]=\frac{29}{3}\times \frac{9}{1}[/tex]
[tex]= \frac{87}{1}[/tex]
[tex]=87[/tex]
Test to see if 1/9 goes into 9 2/3 87 times
87 * 1/9
[tex]= \frac{87}{9}[/tex]
[tex]=\frac{29}{3}[/tex]
29/3 as a mixed fraction is 9 2/3. So therefore, there are 87 ninths in 9 2/3
At a pizza place, a large pizza cost $7. 50 and toppings cost $0. 50 each. Write an equation the can be used to represent the cost of a pizza, y, which x toppings.
Answer:
7.50 a pizza 0.50 for peporonies
Step-by-step explanation:
Convert the mixed number 1 2/3
to an improper fraction.
Answer:
5/3
Step-by-step explanation:
An improper fraction is a fraction, not in mixed form, where the numerator (top half) is greater than the denominator (bottom half). Since this fraction is 1 2/3, we already have 1 full and 2/3 full. So, since the 1 is full, it means that in fraction form it equals 3/3.
We can finally add the fractions. [tex]2/3+3/3=5/3[/tex].
A mini laptop computer is on sale for 40% off the regular price of $450. How much is the discount? a. $18 b. $27 c. $180 d. $270 Please select the best answer from the choices provided A B C D.
Answer:
C
Step-by-step explanation:
Since the laptop is on sale for 40% off, the discount is 40% of the regular price. Note that they are asking for the discount and not the discounted price.
Discount
= 40% ×$450
= ⅖ ×$450
= $180
Thus, option c is correct.
if you answer you will get points and if it's right :D
1/5=2/10=5/25
To get 2/10, since, in the denominators, to go from 5 to 10, you multiply 5 by 2, I multiplied 1 and 2 to get the answer.
For 5/25, to go from 1 to 5 you multiply 1 by 5, so you multiply 5 by 5, and that's 25, so the denominator for that fraction is 25.
How can you use estimation to find
92 +91 +92 +91 +9?
Answer:
370
Step-by-step explanation:
Round each answer into easier to add numbers. 92 and 91 round down to 90. 9 rounds up to 10.
Answer:
aprox 280
Step-by-step explanation:
if you need to add these numbers quickly you can estimate either with an overestimation or under estimation:
for an over estimation, you can find the nearest 10 or 100 that each value is so for this you have 92 + 91 +92 +9 which is close to 100 +100+100+10
so using this you can quickly guess that it would be somewhere around 310
for an under estimation you can do the same thing but rounding down so we instead would add 90 + 90 + 90 + 10 which gives 280
now using both we know the answer would be somewhere between 280 and 310

Please help!! Thank you!
Answer:
A. $209.53
Step-by-step explanation:
First, we have to take away 15% from the 850 dollar total so we can divide the remaining amount between the friends.
15% can also be written as the fraction 0.15
850 x 0.15 = 127.5
Now, we subtract the money they put away from the total amount.
850 - 127.5 = 722.5
So, the three friends have $722.50 to split between each other.
To figure out what amount everyone gets, we will first at together the total hours they worked.
17.25 + 18.25 + 14.5 = 50
Since the total hours is 50, we can divide the number of hours Shawn worked by 50 to find out what fraction of the total time he worked.
14 ÷ 50 = 0.29
0.29 is the same as the percentage 29%. This means Shawn worked for 29% of the total time out of his friends.
So, he gets 29% of the 722.50 dollars.
0.29 x 722.5 = 209.525
Round it up to 209.53
Shawn gets $209.53

The equation that represents the value of the car is v = $5000(1.085)^x.
What equation represents the value of the car?Appreciation means when the value of a car increases with the passage of time. The formula that can be used to represent appreciation is:
FV = P (1 + r)^n

What is the value of x?
Enter your answer in the box.
x =
Answer:
x =39°
the total interior angles of a triangle is 180°
let the unknown angle be x,
solve:
x + 39 + 102 = 180°
x = 180° - 39° - 102°
x = 39°
Therefore the unknown angle is 39°

This shape is made of three identical semicircles.
The perimeter of the shape is 36 centimetres.
Another shape is made up using the same semicircles as above.
Answer:
48cm
Step-by-step explanation:
The perimeter of first shape is 36cm. There are 3 semi circle (curves).
Therefore,
3 curves of semicircle (arc length) = 36
1 curve of semicircle (arc length) = 36/3
= 12cm
In picture 2,
4 semicircles (They've mentioned that they used the same semicircle for the 2nd shape also)
So,
4×12 = 48cm

the answer for the first part is 260
the equation is n+8
Step-by-step explanation:
all you need to do is take the starting number witch is 13 then you add 8 and then take that number and add 8 so thats why the equation is n+8 n equaling the starting number and 8 equaling to the reoccurring number.

Maria is building a circular pool. The radius of the pool will be 7 feet. She will put a cover on the pool and build a fence around the pool. How much material will she need to cover the top of the pool?
Answer:
about 154 square feet
Step-by-step explanation:
The area of the pool is given by the formula for the area of a circle:
A = πr²
A = π(7 ft)² = 49π ft² ≈ 153.94 ft²
About 154 square feet of material will be needed to cover the top of the pool.

Additional comment
The circumference of the pool is 2πr, or 14π feet -- about 44 feet.
The circle at the right represents a planet. The radius of the planet is about 4700 km. Find the distance d to the horizon that a person can see
on a clear day from the following height h above the planet
h=2 km
A person can see a distance of approximately km on a clear day from a height of 2 km above the given planet.
Answer:
137.13km
Step-by-step explanation:
A right triangle is formed, where h + r = 2+ 4700= 4702 km is the hypotenuse, r = 4700km is one leg and d is the other leg. By Pythagorean theorem:
4702² = 4700² + d²
d² = 4702² - 4700²
d = √18,804
d = 137.13 km

-10+4(2b+2)=
Answer:
2(4b-1)
Step-by-step explanation:
1. You would have to distribute first. So basically you just multiply 4 · 2b which gives you 8b and then 4 · 2
Answer to first step: -10+8b+8
2. Add the numbers. It should be -10 + 8 which would give you -2
Answer to second step: -2 + 8b
3. Rearranging the terms. So, instead of doing -2 + 8b you would have to do 8b - 2
Answer to third step: 8b - 2
4. 2(4b - 1) Find what times what gives you 8 (not 1 times 8) and the same for -2

Answer:
When f(x) is 0, then x is -1.8.
Step-by-step explanation:
To find this, you simply have to look for the place where the line crosses the x axis. This is where y (or f(x)) is equal to 0. Since this graph only crosses that axis at x = -1.8, that is the number we are looking for.
