The ratio of cats to dogs at a pet store is 4:5 which means
Answers
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.

MO is angle bisector of ∠LMN, so:
m∠LMN = 2*m∠LMOSubstitute with expressions:
6x - 28 = 2(x + 34)Solve for x:
6x - 28 = 2x + 686x - 2x = 68 + 284x = 96x = 24Find m∠NMO:
m∠NMO = m∠LMO = x + 34 = 24 + 34 = 58°Correct choice is D

Let’s start by solving for x:
52=x-15
Add 15 to both sides:
x=67 degrees
Now let’s solve for y:
4y=128
Divide 4 to both sides:
y=32 degrees
1.) x = 67 y = 32
Here's the Solution:
for x:(x-15)° and 52° are vertical Angles so they are congurent.
(x-15)° = 52°x - 15 = 52x = 52 + 15x = 67for y:4y° and 128° are vertical Angles so they are congurent.
4y° = 128°4y = 1284y/4 = 128/4y = 32HOPE THIS HELPS. GOODLUCK:)
Which type of parent function does the equation f(x) = va represent?
A. Cube root
B. Reciprocal
C. Square root
D. Absolute value
Answers
Answer:
reciprocal
Step-by-step explanation:
The function f(x) = √x is represented by the square root type of parent function.
What is Square Root?Square root of a number is the value such that the value when multiplied to itself two times gives the original number.
It is denoted by the symbol √.
Given function is,
f(x) = √x
Here for any value of x, the function is mapped to √x.
That is, the function is mapped to the square root of the x.
Thus it is a square root function.
Hence the function is the square root function.

Answer: the mean would increase and the median would stay about the same
Step-by-step explanation:
The mean would increase and the median would decrease. Then the correct option is A.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
The scores on the push-up portion of a physical fitness test had a mean of 62 and a median of 60. One athlete was absent during the test, and his score was not included in the calculations. If his score of 67 was added to the distribution of scores.
The value of the mean will increase because a score of 67 is more than the mean of 62. And the median will decreases.

we can use the mnemonic VUX/HOY to determine the slope, the type of line, and which axis it corresponds to. VUX/HOY stands for:
Vertical line
Undefined slope
X axis
Horizontal line
0 is the slope
Y axis
according to this, the equation x = 6 is a vertical line
now we can start eliminating answer choices
A. a line containing the point (6,2)
the point lies on the line x = 6, as the x-coordinate in the ordered pair is 6. this is not parallel to the line
B. y = 6
this intersects x = 6 and is not parallel
C. y = 4
this intersects x = 6 as well and is not parallel
D. x = 3
this leaves us with x = 3, which is a vertical line as seen by the equation and therefore x = 3 is our answer

1. Solve
x + 3y = 7
3x + 4y = 11
Answers
Answer:
x = 1 y = 2
Step-by-step explanation:
x + 3y = 7
- Subtract x from both sides.
3y = -x + 7
- Divide both sides by 3 to isolate the variable.
y = -1/3x + 7/3
- Plug the value of y into the other equation.
3x + 4(-1/3x + 7/3) = 11
3x - 4/3x + 28/3 = 11
- Add like terms.
5/3x + 28/3 = 11
5/3x = 5/3
x = 1
- Plug the value of x into the equation.
x + 3y = 7
(1) + 3y = 7
3y = 6
y = 2
