What is the radius of each semicircle in this composite figure?
Answers
Answer:
2cm
Step-by-step explanation:
First, it is important to define both the radius and diameter. A diameter is the length of a line through the center of a circle that touches two points on the edge.
In the semicircle on the top, if we can imagine it making up a full circle, we can note that the bottom center of the semicircle is the center of the full circle, with the line of length 4cm going right through it. Similarly, for the bottom semicircle, as the line between the semicircles is straight, the diameter for that one is 4cm as well.
The radius is equal to half of the diameter. The diameter is 4cm, so the radius is 4cm/2 = 2cm

At Safeway, a pound of apples cost $1.32. Mrs. Terry purchased 7.5 pounds of apples. How much money did
Mrs. Terry spend on apples?
Answers
Answer:
the answer is $1.32×7.5=$9.9
Answer:
£9.90
Step-by-step explanation:
There are 2 ways you can do this. Both are similar.
For the first method it's much quicker but you might need a calculator.
You would simply do 7.5 × 1.32 = £9.90 that should give you the answer.
If you were to do it with out a calculator then what you need to do is 7 × 1.32 = 9.24
Because there is still 0.5 (or 1/2) left from the 7 that you multiplied, you do 1.32 ÷ 2 = 0.66.
Add the 2 numbers together
0.66 + 9.24 = £9.90

Answers
Answer:
( 1, 3)
Step-by-step explanation:
4x+y=7 * 2 = 8x + 2y = 14
8x + 2y = 14
- 3x + 2y = 9
--------------------
5x = 5
x = 1
Now substitute x into the equation for 1
8*(1) + 2y = 14
8 + 2y = 14
2y = 6
y = 3
What is the volume, in cubic ft, of a rectangular prism with a height of 17ft, a width of 11ft, and a length of 18ft?
Answers
Answer:
The answer is 3366 cubic feet.
Step-by-step explanation:
To find the volume of the rectangular prism, use the formula for a rectangular prism, which is V= LWH. Next, plug in the information given from the question, and the formula will look like V= (18ft) (11ft) (17ft).
Then, solve the equation for the answer, and the answer will be 3366 cubic feet.

They’re vertical angles (they’re opposite angles when 2 lines intersect). Since vertical angles are congruent, we can set up an equation to solve for the value of x.
If they’re both equal, we’ll say exactly that in our equation!
2x + 90 = 4x + 30
Combine like terms
2x = 60
Simplify
x = 30
Now, just plug in 30 for one of the x values in either of the equations
2(30) + 90 = 150
Angle = 150 °

Answer:
y = -x⁴ + x² - 2 : D
y = x⁵ + x² + 7 : B
y = x⁶ + 2x³ + 3 : C
Step-by-step explanation:
anyways look at the part with the largest power of x. it will have the biggest impact on the overall value, when x approaches positive or negative infinity.
in the first one this is -x⁴
x⁴ is always positive (for positive and negative x). so, -x⁴ is always negative. therefore, it decreases in both cases when x approaches positive or negative infinity.
in the second one this is x⁵.
this goes with the sign of x. it is getting bigger (it increases), when x approaches positive infinity, and it is getting smaller (it decreases), when x approaches negative infinity.
in the third one this is x⁶.
this is always positive (for positive and negative x). therefore, it increases in both cases when x approaches positive or negative infinity.

A triangular prism whose total surface area = 64 cm2, and its lateral area = 40 cm2, find the area of its base?
Answers
Answer:
Area of its base = 12cm²
Step-by-step explanation:
The Area of its base = 1/2 of its surface area - 1/2 of its lateral area
Its surface area = 64, then 1/2 X 64 = 32cm²
Its lateral area = 40, then 1/2 X 40 = 20cm²
So, Area of its base = 32 - 20 = 12cm²

Answer:
Area of triangle is 23 yd².
Step-by-step explanation:
Given :-
Base of triangle = 8 yd
Height of triangle = 6 yd
To find
Area of triangle
Solution :-
we know that,
Area of triangle = 1 / 2 × base × height
substitute the values
Area of triangle = 1/2 × 8 yd × 6 yd
multiplying the values
Area of triangle = 1/2 × 46 yd²
divide the values
Area of triangle = 46 yd ² /2 = 23 yd².
Therefore, Area of triangle is 23 yd ².
