Answer:
-16/10
Step-by-step explanation:
It's already an improper fraction.
Answer:
-8/5
Step-by-step explanation:
To simplify, you have to divide the numerator and denominator by the same number. In this case, it's 2.
I hope I helped!
We can't simplify anymore, because -8 is composite and 5 is prime :-)
Need Help!!!!!!!!!!!!!! Calculate the area of this figure. Round your answer to the nearest tenth.
Answer:
100
Step-by-step explanation:
we first find the area of the rectangle:
8*10=80
now we find the area of the triangle:
(6*8)/2=24
Now we add the area of the triangle and the rectangle up:
24+80=104
Now we round that up to the nearest ten:
100
DF= 78, DE = 5x -9, EF = 2x + 10, find DE.
Solve for x first.
5x - 9 + 2x + 10 = 78
7x + 1 = 78
7x = 78 - 1
7x = 77/7
x = 11
Then substitute the value of x to find DE.
DE = 5x - 9
5(11) - 9
55 - 9
DE = 46
Therefore, the value of DE is 46
DF= 78, DE = 5x -9, EF = 2x + 10, find DE.
Solution:First, solve for the value of x.
DE + EF = DF(5x - 9) + (2x + 10) = 787x + 1 = 787x = 78 - 17x = 77/7x = 11Then, plug and substitute the value of x to find the DE.
DE5x - 95(11) - 955 - 946Answer:The value of DE is 46

What difference did 0% score make? Does this mean represent Brandee ability more accurately
Because of the test she did not take, Brandee scored a 9.75% lower average than her average score once her teacher allowed her to take the test again.
The average obtained once Brandee's teacher allowed him to present the missing test is much more accurate regarding Brandee's ability, this can be identified since it went from an average of 85.14% with 7 scores, to one of 84.25% with 8 scores, different from the average of 74.5% obtained thanks to that score of 0.
BRANDEE'S AVERAGE CALCULATION.
In the exercise, you can see Brandee's scores are: 80%, 92%, 91%, 75%, 89%, 84%, 0%, and 85%, if you calculate the average in that case:
First Brandee's average = (80 + 92 + 91 + 75 + 89 + 84 + 0 + 85) / 8First Brandee's average = 74.5But when Ms. Juarez allowed her to make up the missed test, in which she got 78%, The average increased too much:
Second Brandee's average = (80 + 92 + 91 + 75 + 89 + 84 + 78 + 85) / 8Second Brandee's average = 84.25As can be identified, most of Brandee's scores are above 80%, therefore, it is considered more accurate that her average is above this value, that is, it is an average that would represent much better the ability of Brandee.

You have a box of tiles, each of which measures 6 by 10 inches. What is the least number of tiles you could use to form a square region? (Use this square to show how they would be arranged.) The prime factorizations of five numbers are given. Use them to find each of A and В
The least common multiple can be used to find the smallest square formed by equal sized shapes
The least number of tiles to be used is 15 tiles
The arrangement of the tiles, with the 6 inch side as base is 3 rows by 6 columns of tiles
The reason the above responses are correct is as follows:
The unit area of each square tile = 6 inches by 10 inches
Therefore, the area of the square obtained is a factor of 6 × 10 = 60 in.²
The side of the square have 6 and 10 as factors
The lowest common multiple of 6 and 10 is 30
Therefore, the smallest square has a side length of 30 inches and an area of 30 in. × 30 in. = 900 in.²
The least number of tiles = Area/(The area of each tile)
Therefore, the least number of tiles = 900 in.²/(60 in.²/tile) = 15 tiles
The least number of tiles = 15 tiles
The arrangement of the 15 tiles are as follows;
With the 6 inch width side as the base, five tiles are arranged along the base, three more rows are constructed using the same process to form the 30 inch by 30 inch square to give 3 rows by 6 columns of tiles

If AB=CD, CD = 9in, BC = 5x, and AD = 53 in. , find BC
Answer:
BC = 35in.
Step-by-step explanation:
AD says the entire line is 53in.
AB says it is equal to CD.
CD says it equals 9in so AB + CD = 18in.
BC says it equals 5x.
AB+BC+CD = AD
(9) + (5x) + (9) = 53
5x + 18 = 53
Subtract 18 from both sides
5x = 35
We can stop here because we know that BC = 5x and 5x = 35in.

When we get a sale value or reduced value to find
This is a short cut of workings in bold to find correct value.
10% of 510 = 51
20% of 510 = 102
510-102 =408
17 x 30 = 510 Not correct as calculated before taxes.

An angle measures 85.2° less than the measure of its complementary angle. What is the measure of each angle?
Answer:Complementary angles are two angles whose sum is 90 degrees.
Let x represent one of the angles.
The other angle which is 84.2 degrees less would be x - 84.2.
Using this, we can write an equation.
x + (x-84.2) = 90.
Combine like terms: 2x - 84.2 = 90
Add 84.2 to both sides of the equation.
2x = 174.2
Divide by 2: x = 87.1
and x - 84.2 would equal 2.9. to check: does 87.1 + 2.9 = 90? yes.

The ratio of cats to dogs at a pet store is 4:5 which means
Step-by-step explanation:
The ratio of cats to dogs at a pet store is 4:5. It means that if there are 4 cats in the store then there are 5 dogs, if there are 8 cats(4×2) there then there will be 10 dogs(5×2).
The number of cats is 16 if the ratio of cats to dogs is 4:5 if there are 20 dogs.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
The complete question is:
The ratio of cats to dogs is 4;5 if there are 20 dogs. How many cats are there?
It is given that:
The ratio of cats to dogs at a pet store is 4:5
Let 4x be the cats and 5x be the dogs
5x = 20
The above equation is a linear equation in one variable.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
x = 20/5
x = 4
Number of cats = 4x
Plug x = 4 in the above expression:
= 4(4)
= 16
Thus, the number of cats is 16 if the ratio of cats to dogs is 4:5 if there are 20 dogs.

Answer: multiply 750 and 12
Divide that by the 14%
Step-by-step explanation:
Write in standard form.
y^2+14y-5x+64=0
[tex] \hookrightarrow \: {y}^{2} + 14y - 5x + 64 = 0[/tex]
[tex] \hookrightarrow \: 5x = {y }^{2} + 14y + 64[/tex]
[tex] \hookrightarrow \: 5x = {y}^{2} + 14y + 49 + 15[/tex]
[tex] \hookrightarrow \: 5x = (y + 7) {}^{2} + 15[/tex]
[tex] \hookrightarrow \: x = \dfrac{(y + 7) {}^{2} + 15 }{5} [/tex]
[tex] \hookrightarrow \: x = \dfrac{1}{5} (y + 7) {}^{2} + 3[/tex]
therefore, the correct option is B
Answer:
x = (1/5)(y + 7)² + 3
Step-by-step explanation:
Given that,
→ y² + 14y - 5x + 64 = 0
Let's find the required solution,
→ y² + 14y - 5x + 64 = 0
→ 5x = y² + 14y + 64
→ 5x = y² +14y +49 + 15
→ 5x = (y + 7)² + 15
→ x = [(y + 7)² + 15]/5
→ [x = (1/5)(y + 7)² + 3]
Hence, it is the correct answer.

The volume of a sphere is 36-pie-ft-three squared
what is the radius of the sphere use the formula v= 4/3 -pie- r-3 squared
Answer:
3 ft
Step-by-step explanation:
V = 4/3 π r³
36 π = 4/3 π r³
=> eliminate π
36 = 4/3 r³
r³ = 36×¾
r³ = 27
r = ³√27
r = 3
so, the radius of the sphere = 3 ft
Volume=36π
