Answer:
4
Step-by-step explanation:
If Annie and her grandmother play with 5 of the puppies, subtract 5 from 53 to get 48. Since there are 12 volunteers, divide 48 by 12 to get 4. So, each volunteer plays with 4 puppies. My work is shown below.
53-5=48
48/12=4
PLEASE MARK ME AS BRAINLIEST
Answer: 4
Step-by-step explanation: Hi there
1. Subtract the number of puppies Annie plays with from the total number of puppies. 53-5=48
2. Divide the number of remaining puppies by the number of volunteers. 48/12=4
Therefore, each volunteer plays with 4 puppies.

A garden measuring 15 meters by 20 meters is to have a pedestrian pathway installed
all around it, increasing the area to 336 square meters.
a. Write an expression to represent the area of the total garden including the
pathway.
b. What will be the width of the pathway?
The area of the garden is the amount of space on the garden.
The area of the total garden is (x + 15)(x + 20)The width of the pathway is 1 meterThe expression of the areaThe dimensions of the garden is given as:
15 meters by 20 meters
Let the width of the pedestrian pathway be x.
So, the area of the total garden is:
[tex]Area=(x + 15)(x + 20)[/tex]
The width of the pathwayIn (a), we have:
[tex]Area=(x + 15)(x + 20)[/tex]
The total area is given as: 336.
So, we have:
[tex](x + 15)(x + 20) = 336[/tex]
Expand
[tex]x^2 + 35x + 300 = 336[/tex]
Collect like terms
[tex]x^2 + 35x + 300 - 336 = 0[/tex]
Evaluate
[tex]x^2 + 35x - 36 = 0[/tex]
Expand
[tex]x^2 + 36x -x - 36 = 0[/tex]
Factorize
[tex]x(x + 36) -1(x +36) = 0[/tex]
Factor out x + 36
[tex](x + 36)(x -1) = 0[/tex]
Solve for x
x = -36 or x =1
The width cannot be negative.
Hence, the width of the pathway is 1 meter

What is the probability of landing on red and rolling a number greater than 2?
Using it's concept, considering a spinner with four sections and a die with 6 numbers, there is a [tex]\frac{1}{6}[/tex] probability of landing on red and rolling a number greater than 2.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
The spinner has 4 sections, one of which is red, hence P(A) = 1/4.The die has 6 numbers, four of which are greater than two, hence P(B) = 4/6.The events are independent, hence:
[tex]P(A \cap B) = P(A)P(B) = \frac{1}{4} \times \frac{4}{6} = \frac{1}{6}[/tex]
[tex]\frac{1}{6}[/tex] probability of landing on red and rolling a number greater than 2.

Answer:
[tex]y=-7x+4[/tex]
Step-by-step explanation:
Formulae
Slope-intercept form of a linear function: [tex]y = mx + b[/tex]
(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)
Point-slope form of a linear function: [tex]y-y_1=m(x-x_1)[/tex]
(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is a point on the line)
Slope formula
[tex]\textsf{slope}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
(where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are points on the line)
Solution
Choose 2 points on the line:
Let [tex](x_1,y_1)[/tex] = (0, 4)Let [tex](x_2,y_2)[/tex] = (1, -3)Find the slope using the slope formula:
[tex]\implies \textsf{slope}=\dfrac{-3-4}{1-0}=-7[/tex]
Substitute found value for [tex]m[/tex] and point (0, 4) into the point-slope formula:
[tex]\implies y-4=-7(x-0)[/tex]

What is the slope of a line that passes through the points (5,-3) and (13, -9)
Step-by-step explanation:
the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to the other.
so, we see
x changes by +8 (from 5 to 13).
y changes by -6 (from -3 to -9).
so, the slope is -6/+8 = -3/4
Hello.
Let's find the slope using the slope formula:
[tex]\mathrm{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]
[tex]\mathrm{\displaystyle\frac{-9-(-3)}{13-5} }[/tex]
[tex]\mathrm{\displaystyle\frac{-9+3}{13-5} }[/tex]
[tex]\mathrm{\displaystyle\frac{-6}{8} }[/tex]
The fraction can be simplified:
[tex]\mathrm{\displaystyle-\frac{3}{4} }[/tex]
Therefore, the slope is
[tex]\mathrm{\displaystyle-\frac{3}{4} }[/tex]
