Answer:
25 minutes
Step-by-step explanation:
Because 3 × 5 is 15 problems so multiple he 5 minutes by 5 and you get 25 minutes.
9. Which is a solution of the equation 5(x – 8) = -55 ?
a) x = 3
b) x = 13
c) x = -3
d) x = -9.4
Answer: c. x = -3
5(x - 8) = -55
⇔ 5x - 40 = -55
⇔ 5x = -55 + 40 = -15
⇔ x = -15/5
⇔ x = -3

30(30-x)=540 what is the value of x
Answer:
x = 12
Step-by-step explanation:
Original equation:
30(30 - x) = 540
Use distributive property
30 · 30 = 900
30 · (-x) = -30x
Plug these values back into the equation
900 - 30x = 540
Subtract 900 from both sides
-30x = -360
Divide both sides by -30
x = 12

The points (0, -1) and (4,5) lie on the straight line L
Work out the gradient of L.
Answer:
gradient = [tex]\frac{3}{2}[/tex]

Which transformation rule below translate points 5 units to the left and 2 units up? *
(1 Point)
(x y) --> (x + 5, y + 2)
(x, y) --> (x - 5. y - 2)
(x, y) --> (x + 5. y - 2)
(x, y)--> (x - 5. y + 2)
Please I need help
Answer:
(x, y)--> (x - 5. y + 2)Step-by-step explanation:
Given the coordinate (x, y), when transforming the coordinate, up and right, the value of the constant we are using must be added to the coordinate since positive x axis acts towards the right side and the positive y axis acts upwards.
Also, when transforming the coordinate down and left, the value of the constant we are using must be subtracted from the coordinate since negative x axis acts towards the left side and the negative y axis acts downwards.
According to the question, we are to translate the coordinate (x, y) 5 units to the left and 2 units up,
Translating 5 units to the left means the x coordinate will become x--> (x-5)
Translating 2 units up means the y coordinate will become x--> (x+2)
Hence the correct transformation rule will be (x, y)--> (x - 5. y + 2)

Step-by-step explanation:
The length of rectangle A is 7.4 cm and the width is 4.8 cm. The perimeter of rectangle B is 14.9 cm. How much is the perimeter of rectangle A than the perimeter of rectangle B?
Answer: 9.5 cm
Step-by-step explanation:
First we have to find the perimeter of rectangle A:
Formula for perimeter of a rectangle or square is: [tex]2(a+b)[/tex]
Putting the length and width in: [tex]2(7.4+4.8)[/tex]
Solve it to get: 24.4 cm
Subtract 14.9 from 24.4 to get 9.5 cm
A 52kg person walks from the ground to the roof of 78.52m tall building. How much gravitational potential energy is there?USE GRESA METHOD
Answer:
P = 40013.792 J
Step-by-step explanation:
Given that,
Mass of a person, m = 52 kg
The height of the building, h = 78.52 m
We need to find the gravitational potential energy at this point. It is given by the formula as follows :
P = mgh
Where g is acceleration due to gravity
P = 52 kg × 9.8 m/s² × 78.52 m
P = 40013.792 J
So, the gravitational potential energy is 40013.792 J.
which is closer to 0 3/8 or -1/3
Answer:
-1/3 is closer to 0
Step-by-step explanation:
3/8 is between 0 and -1/3. We need to determine if 3/8 is closer to -1/3 or closer to zero. Since -1/3 is smaller than 3/8, 3/8 is closer to -1/3. Since 3/8 is closer to -1/3, 3/8 rounded to the nearest -1/3 is -1/3.

how is perimeter measured?
A)Using the metric system
B)Cubic units
C)Linear units
D)Units squared
Perimeter is the linear distance around an object.
It is measured in c) linear units
Perimeter is measured in linear units .
Given,
Perimeter
So,
Perimeter is the linear distance around an object.
For example,
Perimeter of circle is 2πr which means that the region which is considered is outer region along the radius of the circle and complete one circle that is 2π .
Similarly,
Perimeter of square is 4a that means the square is covered along its side 4 times that is along the sides of square .
Thus
It is measured in linear units.
