The answer is C: multiply by 2
Answer:
A. 74 cm
Step-by-step explanation:
First, we break the rhombus down into similar shapes,
The area of 2 triangles = The area of a square
So we take the triangle from the left and combine it with the triangle on the right, it should make a rectangle, Then calculate the area of the rectangle,
10 multiplied by 5 =50
Thats the area of rectangle 1
Rectangle 2
3 multiplied by 6 = 18
Triangle
4 times 3 divided by 2 = 6
Thus
6 + 18 + 50 = 74

Answer:
A. Q = 15 °C
B. 0.4 °C
C. Q = 23 °C
Step-by-step explanation:
The following equation models the temperature of Quin's home,
Q = 15 + 0.4t
Where Q is the temperature in degree Celsius and t is the time in minutes
A. What was the temperature when Quinn returned from vacation?
At this time, t = 0 since Quin is just arrived
Q = 15 + 0.4(0)
Q = 15 °C
B. how much does the temperature increase every minute?
0.4(t)
0.4(1)
0.4 °C
The temperature increases by 0.4 centigrade every minute.
C. How much will the temperature increase if Quinn leaves the heat on for 20 minutes
For t = 20 mins
Q = 15 + 0.4(20)
Q = 15 + 8
Q = 23 °C
