The number 12 would work because subtracting 2 from 12 is ten and that's basically like adding 12 to -2 :)
Answer:
58
Step-by-step explanation:
There would be 58 nickels and 42 dimes. This can be found out by
1. 100 - 16 = 84
2. 84/2 = 42
3. 42 + 16 = 58
making 42 dimes and 58 nickels.
Answer:
6.5
Step-by-step explanation:
We need to solve out for x , the given Equation is ,
x - 3x + 2 = -11
-2x = -11 -2
-2x = -13
x = -13/-2
x = 6.5
Answer:
1. a) 8 cm × 8 cm = 64 sq cm
b) (64 cm²) × 6 squares = 384 sq cm
2. 152 sq cm
Step-by-step explanation:
1. The area of any rectangle is the product of its length and width. For a square, length and width are the same. The square faces of your die have length and width of 8 cm, so the area is (8 cm) × (8 cm) = 64 sq cm.
A cube has 6 faces of identical size, so the total surface area is 6 times the area of one face. Your cube's surface area is 6 × 64 sq cm = 384 sq cm.
___
2. A rectangular prism (cuboid) has 6 faces—3 pairs that are the same size. The area is the total of the areas of these pairs of faces. It can be computed by ...
A = 2(LW + WH + LH)
For your rectangular prism, this is ...
A = 2((8 cm)×(6 cm) + (6 cm)×(2 cm) + (8 cm)×(2 cm))
= 2(48 sq cm + 12 sq cm + 16 sq cm)
= 2×(76 sq cm)
= 152 sq cm
Answer:Graph A.
Step-by-step explanation:
Graph A.
Step-by-step explanation:
We will try to understand the graph plotted for the change in temperature for whole day.
In the morning, temperature starts out around 50°F. As the day goes on, the temperature rises first slowly- Slope of the first line will be less.
Then temperature rises more quickly - Slope of the second line will be more than first line.
It stays constant for an hour- third line will be parallel to the x-axis for one hour gap.
Then the temperature dropped down slowly - Last line of the graph will go down.
By the understanding we made for the graph we find graph A is the answer.
