Daud can jog 4 miles in 75 minutes. What is David's jogging rate per hour?
Answer:
3 mph
Step-by-step explanation:
1 hour = 60 minutes.
4 miles/ 75 minutes = x miles / 60 minutes
240 = 75 x
x = 3.2
3.2 miles per hour
sum of two integers is -30 if one of them is 15 find the other integer pls urgent will mark u the brainliast
Answer:
-45
Step-by-step explanation:
Sum of two integers = -30
one of them = 15
let another number be 'x'
x + 15 = -30
x = -30 - 15
x = -45
so the other number is -45

Calculate the mean of Bryanna's test scores if she has scored 75, 97, and 92 so far this
semester
A 284
o
B
88
c. 75
D
Work Shown:
Add up the values
75+97+92 = 264
Then divide by 3 since there are 3 scores
264/3 = 88
You can write this all as one step
(75+97+92)/3 = 88
So in short, you add the scores and then divide by the number of scores.
What is the equation of a line that is perpendicular to the line y = 2x + 4 and passes through the point (-2, 3)?
Answer:
[tex]y=-\frac{1}{2} x+2[/tex]
Step-by-step explanation:
The given equation is written in slope-intercept form:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptx and y are the corresponding coordinate points (x,y)The slope is 2:
When two lines are perpendicular, their slopes will be opposite reciprocals. Find the slope of the line perpendicular to the given equation:
[tex]m_{1}=2[/tex]
This can be seen as:
[tex]m_{1}=\frac{2}{1}[/tex]
Flip the fraction (reciprocal):
[tex]\frac{2}{1}[/tex] → [tex]\frac{1}{2}[/tex]
Now find the opposite:
[tex]\frac{1}{2}[/tex] → [tex]-\frac{1}{2}[/tex]
So the slope of the perpendicular line is:
[tex]m_{2}=-\frac{1}{2}[/tex]
Now make an equation written in point-slope form:
[tex]y-y_{1}=m(x-x_{1})[/tex]
where:
m is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the corresponding coordinate points [tex](x_{1},y_{1})[/tex]Insert information:
[tex]y-3=-\frac{1}{2} (x-(-2))\\\\y-3=-\frac{1}{2} (x+2)[/tex]
Simplify to slope-intercept form. Solve for y:
Use the distributive property:
[tex]y-3=-\frac{1}{2}(x)-\frac{1}{2} (2)\\\\ y-3=-\frac{1}{2} x-1[/tex]
Add 3 to both sides to isolate the variable:
[tex]y-3+3=-\frac{1}{2} x-1+3\\\\y=-\frac{1}{2} x+2[/tex]
:Done
Which table represents a linear function that has a slope of 5 and a y-intercept of 20?
Answer:
Step-by-step explanation:
Note that if it has a y- intercept of 20, this means that when x = 0 , y = 20
Find the table which shows that :)

sin(2x) = cos(x)cos(x) – sin(x)sin(x)
sin(2x) = sin(x)cos(x) – sin(x)cos(x)
sin(2x) = cos(x)cos(x) + sin(x)sin(x)
sin(2x) = sin(x)cos(x) + sin(x)cos(x)
Answer:
The correct answer is D) sin(2x) = sin(x)cos(x)+sin(x)cos(x)
Step-by-step explanation:
Right answer on Edge
The step 2 will be;
⇒ sin (2x) = sin (x) sin (x) + cos (x) cos (x)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The steps are;
Step 1; sin (2x) = sin (x + x)
Step 3; sin (2x) = 2 sin (x) cos (x)
Now,
Since, The steps of the solution are;
Step 1; sin (2x) = sin (x + x)
Step 3; sin (2x) = 2 sin (x) cos (x)
Hence, We get;
All the steps as;
⇒ sin (2x) = sin (x + x)
⇒ sin (2x) = sin (x) sin (x) + cos (x) cos (x)
⇒ sin (2x) = 2 sin (x) cos (x)
Thus, The expression for step 2;
⇒ sin (2x) = sin (x) sin (x) + cos (x) cos (x)

What does f(1) represent in a sequence?
Answer: First term.
Step-by-step explanation:
An ordered list with a pattern is known as a sequence.It is denoted by [tex]<f(n)>[/tex] or [tex]<a_n>[/tex], where n is any natural number.i.e. Domain for this function is natural number.
Natural number starts with 1.
so, at n=1 f(1) represents the first term in a sequence.
Hence, f(1) represents "first term" in a sequence

4x + 6 = 8x – 10 graphing
Answer:
Step-by-step explanation: First things first, you have to have the variables on one side. To do that, subtract 4x from each side.
4x + 6 = 8x - 10
-4x -4x
Now you have your equation that is ready to graph.
6 = 4x - 10
Use a graphing calculator and put in the equation. You can also go to desmos.com
When you are done you will see your graph as well as the answer.

4(r + 20) = 1/5(20r + 400)
Answer:
r = r
Step-by-step explanation:
4(r + 20) = 1/5(20r + 400)
4r + 80 = 4r + 80
- 80 - 80
4r = 4r
4 4
r = r
Answer:
no solution
Step-by-step explanation:
4(r + 20) = 1/5(20r + 400)
4r + 80= 4r+ 80
-4r -4r
80= 80

Audrey has already scored 53 points,and scored 22 more points with every coin she collects.How many coins does Audrey have to collect to score a total of 97 points
Answer:
Audrey needs to collect 3 more coins.
Step-by-step explanation:
Since she already scored 53 points, we have to find out how many more points she needs to score 97.
So, 97-53=45 points.
The problem says that each coin Audrey collects is worth 22 points. Therefore, 45 divided by 22= 2 remainder 1. However, if she only collects two more coins, Audrey will only have 96 points in total, not 97.
So, add another coin to make 3.

How much carpet would you need in square feet to cover a floor with dimensions of 12 feet by 15 feet?
Answer:8
Step-by-step explanation:
Area = Length x Width.
simple room measurement
Measure the length using the distance from one wall to the opposite wall.
Measure the width from wall to wall.
Add 2 to 4 inches to each side. This accounts for waste, doors and slanting walls. It’s easy to cut a little off for a perfect fit, but it’s impossible to add without creating unsightly seams.
Multiply the length times the width or enter those into the calculator above. This is your total square footage for that room.
Repeat this process for each room.

To boil rice, start by combining water and rice in a pot at a ratio of 3:1. How many cups of water are need for a batch that uses eight cups of rice?
Answer:
Step-by-step explanation:
To boil rice you use the following ratio
Water : Rice
3 : 1
? : 8
Basically what the ratio 3:1 means is that for every 3 cups of water, you need 1 cup if rice.
6 cups of water, you need 2 cups of rice (6:2)
9 cups of water, 3 cups of rice (9:3)
Etc.
All you would have to do is multiply 3 by 8 to find out how much water she needs for 3 cups of rice :)
Answer:
ok the ratio of water to Rice is 3:1 meaning water is 3 rice is one and your child that we have 8 cups of rice so really quite the ratio of rice to the number of cups of rice so it will be if one is equals to 8 what about 3 that is the ratio that represents water so we'll cross multiply so that you have 3 * 8/1 and the answer is 24 so the number of cups of water needed is 24
