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.

[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.

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.

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

Find the coordinates of the midpoint of a segment with given endpoints
Answer:
[tex]\boxed {\boxed {\sf ( - \frac{9}{2}, -1) \ or \ (-4.5, -1) }}[/tex]
Step-by-step explanation:
We are asked to find the midpoint of a line segment. When you find the midpoint, you essentially find the average of the x-coordinates and the y-coordinates. The midpoint formula is:
[tex](\frac {x_2+x_1)}{2}, \frac{y_2+y_1}{2})[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the endpoints of the line segment. we are given the endpoints R (-6, 1) and S (-3, -3). If we match the value and the corresponding variable we see that:
x₁= -6 y₁= 1 x₂= -3 y₂= -3Substitute the values into the formula.
[tex]( \frac{-3 + -6}{2} , \frac{ 1+ -3}{2} )[/tex]
Solve the numerators.
-3 + -6 = -9 1 + -3 = -2[tex](\frac {-9}{2}, \frac {-2}{2})[/tex]
Divide.
[tex]( - \frac {9}{2}, -1})[/tex]
The fraction can also be written as a decimal.
[tex](-4.5 , -1)[/tex]
The midpoint of the line segment RS is (-9/2, -1) or (-4.5, -1).

An equation for the nth term of the arithmetic sequence is aₙ=9-3n.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.
The given arithmetic sequence is 6,3,0,-3,...
Here, first term a=6 and common difference is 3-6=-3
Substitute a=6 and d=-3 in aₙ=a+(n-1)d, we get
aₙ=6+(n-1)(-3)
aₙ=6-3n+3
aₙ=9-3n

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.
