Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer:
6 [tex]\frac{1}{12}[/tex] (6 1/12)
Question explanation:
First: 9 [tex]\frac{3}{4}[/tex] (9 3/4)
Convert any mixed number to fractions.
Then you initial equation becomes:
[tex]\frac{49}{4} - \frac{5}{2}[/tex]
(49/4 - 5/2)
Applying the fractions formula for subtraction,
(49 x 2) - (5 x 4)
4 x 2
98 - 20
8
= [tex]\frac{78}{8}[/tex]
(78/8)
Simplifying 78/8, the answer is:
9 [tex]\frac{3}{4}[/tex]
(9 3/4)
Second: 5 [tex]\frac{3}{4}[/tex] (5 3/4)
Convert any mixed numbers to fractions.
Reduce fractions where possible
Then your initial equation becomes:
39 - 4
4 - 1
Applying the fractions formula for subtraction.
(39 x 1) - (4 x 4)
4 x 1
39 - 16
4
= [tex]\frac{23}{4}[/tex] (23/4)
Simplifying 23/4, the answer is
5 [tex]\frac{3}{4}[/tex]
(5 3/4)

Answer:
[tex]6\frac{1}{12}[/tex] yards
Step-by-step explanation:
Marcella bought 12 1/4 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.
The amount ribbon she had at the beginning: [tex]12\frac{1}{4}[/tex]
The amount she used: [tex]2\frac{1}{2} +3\frac{2}{3}\\[/tex]
Our expression: [tex]12\frac{1}{4} -(2\frac{1}{2} +3\frac{2}{3} )[/tex]
LCM of 2, 3, and 4: 12
2:
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
3:
3, 6, 9, 12, 15, 18
4:
4, 8, 12, 16, 20
[tex]12\frac{1}{4} -(2\frac{1}{2} +3\frac{2}{3} )\\\\\frac{4*12+1}{4} -(\frac{2*2+1}{2} +\frac{3*3+2}{3})\\\\\frac{49}{4}-(\frac{5}{2}+\frac{11}{3})\\\\\frac{147}{12}-(\frac{30}{12}+\frac{44}{12})\\\\\frac{147}{12}-\frac{74}{12}\\\\\frac{73}{12}\\\\6\frac{1}{12}[/tex]
Therefore, Marcella will have [tex]6\frac{1}{12}[/tex] yards of ribbons left.

Determine the length of the unknown side of the right triangle. If it is not an exact answer, what integer is it closest to? (Don't forget to include units!)
Answer:
12in
Step-by-step explanation:
15in squared - 9in squared is 144in and the square root of 144 is 12
Answer:
12 in
Step-by-step explanation:
Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
let x = unknown side
Given:
a = xb = 9c = 15Substituting the given values into the equation:
⇒ x² + 9² = 15²
⇒ x² + 81 = 225
⇒ x² + 81 - 81 = 225 - 81
⇒ x² = 144
⇒ x = √(144)
⇒ x = ±12
As the length is positive, x = 12 only.
Therefore, the length of the unknown side is 12 in.

Step-by-step explanation:
What is the measure of 1 if 1 is (2x - 3) and 2 is (8x)?
Step-by-step explanation:
(2x - 3) + 8x = 180 (linear pairs)
10x - 3 = 180
10x = 180 + 3
10x = 183
x = 183÷10
x = 18.3
1 = 2x - 3
2 × 18.3 - 3
= 33.6
2 = 8x
8 × 18.3
146.4
Angle 1 + Angle 2 = 180
33.6. + 146.4. = 180

The distance of planet Mercury from the Sun is approximately 5.8 ⋅ 107 kilometers, and the distance of planet Venus from the Sun is 1.1 ⋅ 108 kilometers. About how many more kilometers is the distance of Venus from the Sun than the distance of Mercury from the Sun?
5.2 ⋅ 107 kilometers
4.7 ⋅ 108 kilometers
5.2 ⋅ 108 kilometers
5.7 ⋅ 109 kilometers
I NEED THIS ANSWER ASAP
Answer:
5.2
Step-by-step explanation:
distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.
simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.

The volume of a sphere is 1,766,250 cubic meters. What is the radius of the sphere? Use 3.14 to approximate pi.
Answer:
75m^3
Step-by-step explanation:
[tex]\hookrightarrow \: volume = 1766250 {m}^{2} [/tex]
As we have,
[tex]\hookrightarrow \: volume = \frac{4}{3} \pi {r}^{3} [/tex]
Now,
[tex]\hookrightarrow \: 1766250 {m}^{3} = \frac{4}{3} \times 3.14 \times {r}^{ 3} \\ \hookrightarrow \: 5298750 {m}^{3} = 12.56 {r}^{3} \\ \hookrightarrow \frac{5298750 {m}^{3} }{12.56} = {r}^{3} \\ \hookrightarrow {r}^{3} = 421875 {m}^{3} \\ \hookrightarrow r = \sqrt[3]{421875 {m}^{3} } \\ \hookrightarrow 75 {m}^{3} [/tex]

Oliver read for 450 minutes this month. His goal is to read for 10% more minutes next month.
If Oliver meets his goal, how many minutes will he read in all during the two months?
Oliver will read __minutes in the 2 months.
Answer:
495 min
Step-by-step explanation:
Answer:
945 minutes
Step-by-step explanation:
The first step is to find 10% of 450:
[tex]\frac{10*450}{100*1}[/tex]
10 times 450 is 4500 and 100 times 1 is 100
Then 4500 divided by 100 and the answer is 45 minutes.
After that add that 10% of 450 ( 45 ) to 450 to find the minutes he reads in the next month and the answer is 495 minutes.
So because you want the time he read in the two months add 450 and 495 tp get:
450 + 495 = 945
So Oliver read for 945 in the 2 MONTHS.

Subtract 1/2 from 1, you get 1/2.
Answer:
There is more powder in a whole, one.
The least here is 1/2, because 3/4 is beyond halfway of 1 and 1/2 is exactly halfway.
So, we subtract the least from the greatest which is;
1 - 1/2 = 1/2
Can somebody please solve this? It's a coordinate thingy
Answer:
Coordinates involve two points. (x,y)
Too find a pair (coordinate), use the x and y lines on the graph and see where the point falls.
For example
Point A is number 1 on the y axis
number -4 on the x axis
So, you would write the coordinate out at
(-4,1)
The y axis values are the second point, so after you plot all of letters, use the y axis numbers and number them from least to greatest so you can find the mystery word.
Use the order of operations to evaluate.

This figure represents a planter.
How much soil will it take to fill the planter?
Enter your answer in the box.
ft³
Answer:
22ft^3
Step-by-step explanation:
I took off the small bit to the bottom right first, then found the volume of the larger part (19). Then I added the volume of the smaller part (3). This gave me the answer of 22ft^3.
The volume of planter is 27 cubic feet .Therefore, amount of soil is needed to fill the planter will be 27 cubic feet.
Volume of the cuboid:Volume of the cuboid is the total space occupied by the cuboid in the three dimensional space. It is calculated as:
Volume of cuboid = length × breadth × height
According to the given question
Planter is made up of two cuboids.
Therefore,
Amount of soil needed to fill the planter= volume of the planter
so, volume of the planter=(3×2×3)+(3×1×3)=27 cubic feet.
Hence, 27 cubic feet soil is need to fill the planter.
