Answer:
∠A = 120°
∠B = 60°
Step-by-step explanation:
Since, ∠A and ∠B form a linear pair.
Therefore,
∠A + ∠B = 180°.....(1)
It is given that:
∠A = 2∠B..... (2)
From equations (1) & (2)
2∠B + ∠B = 180°
3∠B = 180°
∠B = 180°/3
∠B = 60°
So, ∠A = 2∠B = 2*60°
∠A = 120°

Nathan bikes every 2 days and swims every 5 days. He biked October 2 and swam October 5th. On what day will be swim and bike on the same day? Either, the 4th, 8th, 10th, 12th, 15th, 20th.
Answer: See explanation
Step-by-step explanation:
To solve this, we have to calculate the lowest common multiple of 2 and 5. This will be:
Multiples of 2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 ....
Multiples of 5 = 5, 10, 15, 20 ....
This means that he will swim and bike every 10th day together. This will be on the 10th, and 20th in October.
Answer:
On the 10th!

The slope of the line that passes through the points (5, 10) and (2, 12) is?
Answer:
[tex]\boxed{\sf m=-\cfrac{2}{3}}[/tex]
Step-by-step explanation:
In order to fins the slope we can either use the slope formula m = (y_2-y1)/(x2 – x1) or the standard line equation, y = mx + b to solve for the slope, m.
Using two points on the line, we can find the slope by finding the rise and the run
Slope formula :-
[tex]\boxed{\sf m=\cfrac{rise}{run} =\cfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\sf \left(x_1,\:y_1\right):\left(5,\:10\right)[/tex]
[tex]\sf \left(x_2,\:y_2\right):\left(2,\:12\right)[/tex]
[tex]\sf m=\cfrac{12-10}{2-5}[/tex]
[tex]\sf m=-\cfrac{2}{3}[/tex]

Step-by-step explanation:
Help pls and thank:)
Answer:
y=-3x+2
Step-by-step explanation:
Slope-intercept form is given by the equation y=mx+b, where m is defined as the slope and b is defined as the y-intercept (the value on the y-axis that the line crosses). First we can determine the slope by using the slope formula.
m=(y2-y1)/(x2-x1), given two points (x1, y1) and (x2, y2). Keep in mind you can choose which point is (x1,y1) and which is (x2,y2) as long as you are consistent.
Plugging in for (-1,5) and (1,-1), you will get:
m=(-1-5)/(1-(-1))=-6/2=-3
Next, we need to find the y-intercept. For this problem, you can determine it is 2 by looking at the graph of the line. We now have both components to create the slope-intercept form.
m=-3, b=2
y=-3x+2

1. The product of 4, and a number decreased by 7, .is 100. Find the number
Answer:
32
Step-by-step explanation:
As per what is given
- the product of 4 and a number decreased by 7 (4 times that number let us call it x, minus 7)
- equals 100, the equation formed equals 100
Form an equation;
4(x - 7) = 100
Solve using inverse operations;
4(x - 7) = 100
/4 /4
x - 7 = 25
+7 +7
x = 32

Mary went shopping on the sales tax holiday (yeah, no sales tax!). She had a
coupon for $20 off any order and two gift cards for $25. She bought two pairs
of pants for $16 each, three shirts for $14 each, and a coat for $80. If Mary
used her coupon and gift cards, how much money did she have to pay?
Answer:
$20.80 total cost
$84
Step-by-step explanation:
coupon for $20 off any order = -20
two gift cards for $25 = 2 x -25 = -50
bought two pairs of pants for $16 each = 2 x 16 = 32
three shirts for $14 each = 3 x 14 = 42
coat for $80 = 80
-20 - 50 + 32 + 42 + 80 = $84

What is the inverse function of f (r) = r/2?
Answer:
Step-by-step explanation:
The fee for a service call from a plumber can be modeled with the function C(h)= 75 + 20h, where C is the total cost of the service call and h is the number of hours the plumber spends working on the problem. (MAFS.912.F-IF.1.2) A. How much does the plumber charge per hour? 3. What is the value of C(3)? 1. What does this represent in terms of the problem?
Answer:
20 ; $135 ; service charge for 3 hours spent is $135
Step-by-step explanation:
Given that :
Service fee equation model :
C(h)= 75 + 20h
C = total cost of the service call
h = number of hours the plumber spends working on the problem
The charge per hour is the gradient or slope of the linear equation. From the equation, the slope is of the equation is related to bx from. The general form of a linear equation where b = gradient or slope(charge per hour) and x = number of hours
bx = 20h
b = 20
Charge per hour = 20
C(3) = 75 + 20(3)
75 + 60 = 135
This means that total service call charge for a plumber who spends three hours fixing a problem is $135

Lily drives 90 miles in 2 hours. If she drives at the same rate, how far does lily travel in each of the following time intervals: 1 hour, 1/2 hour, and 3 hours? Please solve in at least two different ways. You could make a bar model, double number line, ratio table, or graph
How far does she drive in 3 hours
Answer:
1 hour= 45 miles
1/2 hour=22.5 miles
3 hours= 135
Step-by-step explanation:
just work out one hour by halving 90 miles which is 45. Then work out the rest by halving again and multiplying by 3.
Answer:
1st way:
90/2=45
1 hour = 45 miles
45/2=22.5
0.5 hour = 22.5 miles
45+22.5=67.5
1.5 hour = 67.5 miles
67.5x2=135
3 hours = 135 miles
2nd way:
90 miles - 2 hours
1 hour - 60 minutes
60x2=120
90/120=0.75
1 minute - 0.75 miles
0.75x60=45
1 hour = 45 miles
60:2=30
60+30=90
0.75x90=67.5
1.5 hour = 67.5 miles
60x3=180
0.75x180=135
3 hours = 135 miles

Suppose que le rayon d'un cylindre est indentique à sa hauteur. Qu'arriverait-il au volume de ce cylindre si le rayon était multiplié par deux et si sa hauteur était la moitié
Answer: The volume is doubled.
Step-by-step explanation:
I will answer in English.
This says that:
"The radius of a cylinder is equal to its height, what would happen to the volume of this cylinder if the radius is doubled, and the height is halved?"
The volume of a cylinder of radius R y height H is:
V = pi*R^2*H
In this case, the radius is equal to the height, then the initial volume is:
V = pi*(R^2)*R = pi*R^3
Now, for the new cylinder we will have:
Radius = 2*R
Height = R/2
Then the new volume is:
V' = pi*(2*R)^2*(R/2)
V' = pi*4*R^2*(R/2)
V' = (4/2)*pi*R^2*R
V' = 2*pi*R^3
And pi*R^3 was the volume of the original cylinder, then:
V' = 2*V
This means that when the radius is doubled and the height is halved, the volume of the cylinder is doubled.
