Answer:
The answer is 192.33
Step-by-step explanation:
A coaster measures 7 cm in diameter. The total area of five roller coasters must be determined.
The diameter of the coaster is d = 7 cm
The radius is:
[tex]r =[/tex] [tex]\frac{d}{2}[/tex]
[tex]=[/tex] [tex]\frac{7}{2}[/tex] [tex]cm[/tex]
[tex]= 3.5[/tex] [tex]cm[/tex]
The area of the circle is:
[tex]A =[/tex] [tex]\pi r^{2}[/tex]
= (3.14 x 3.5^2) [tex]cm^{2}[/tex]
[tex]= 38.465[/tex] [tex]cm^{2}[/tex]
We now know that the area required for five coasters is 5 x 38.465 [tex]cm^{2}[/tex]
[tex]= 192.325[/tex] [tex]cm^{2}[/tex]
Round 192.325 to the nearest hundredth and you'll get 192.33 as the correct answer.

Find the surface area, in square inches, of a cube whose volume is 8 in³.
Answer:
24 in^2
Step-by-step explanation:
common math
Answer:
Surface area of cube is 24 in²Step-by-step explanation:
In this question we have given volume of cube that is 8 in³. But we know that volume of cube is a³. So ,
[tex] \implies \: a {}^{3} = 8[/tex]
Now ,
[tex] \implies \: a = \sqrt[3]{8} [/tex]
So , cube root of 8 is ,
[tex] \implies \: \boxed{\bold{a = 2}}[/tex]
Therefore, value of a is 2 inches .Now , we are finding surface area of cube . We know that surface area of cube is 6a² . So ,
6 ( 2 )²6 ( 4 )24[tex] \pink{ \boxed{ Therefore, \: surface \: area \: of \: cube \: is \: 24 \: in ^{2} }}[/tex]

Step-by-step explanation:
A bad contains 15 balls of which X is red. Write an expression for the probability that a ball drawn from the bad is red. When 5 more red balls are added to the bag, the probability becomes 3/4. Find the value of X.
Answer:
10
Step-by-step explanation:
The current probability of picking a red ball is [tex]\frac{x}{15}[/tex]. When 5 more balls are added, the probability is 3/4. We can write a ratio for this problem:
[tex]\frac{x+5}{15+5} = \frac{3}{4}[/tex]
When using cross multiplication to solve this, you get 3 * 20 = 4(x+5).
60 = 4x + 20
40 = 4x
x = 10 red balls

For a grocery store's 25 years anniversary sale they ordered 9 crates of grapes with each create containing 10 bags of grapes. After the anniversary sale they had sold all but 3 bags. How many bags of grapes did they sell during the anniversary?
Answer:
87
Step-by-step explanation:
9 x 10 = 90, the store had 90 bags in total at the start. 90 - 3 = 87, the store had sold 87 bags of grapes during the anniversary.
The number of bags of grapes that they sell during the anniversary is 87 bags.
What are Arithmetic operations?Arithmetic operations are the basic part of mathematics which combines the basic operations like addition, subtraction, multiplication and division.
Given that,
For a grocery store's 25 years anniversary sale they ordered 9 crates of grapes with each create containing 10 bags of grapes.
Number of crates of grapes ordered = 9
Number of bags of grapes in each crate = 10 bags.
Total number of bags in 9 crates = 90 bags
After the anniversary sale they had sold all but 3 bags.
Number of bags of grapes sold = 90 - 3 = 87 bags
Hence the number of bags of grapes sold is 87 bags.

State the reason why K = M
Given:
KLMN is a parallelogram.
Answer:
They both are a 90 degree angle.
For the parallelogram KLMN, opposite angles K and M are equal.
What is Parallelogram?Parallelogram are type of quadrilateral in two dimensional geometry which has four sides, four vertices and four angles where opposite sides are equal. They also have the two pairs of sides parallel to each other. These sides are opposite sides.
The sum of the adjacent angles of the parallelogram is equal to 180 degrees and the sum of all angles is equal to 360 degrees. Also the opposite angles are equal.
Given that KLMN is a parallelogram.
Here K and M are opposite vertices and also L and N are opposite vertices.
In a parallelogram, we know that measure of opposite angles will be equal. So here, measure of angles K and M are equal.
Therefore, since angles K and M are opposite angles of the parallelogram, they are equal.

Kira has to carry 170 apples from a farm to the market. How many baskets will she need, given that each basket can hold 46 apples?
Answer:
4 baskets
Step-by-step explanation:
Since 170 divided by 46 equals 3 with a remainder of 32, you use the remainder,32, and change it to one more basket so 3+1=4 so Kira needs 4 baskets.
Answer:
Kira will require exactly four baskets.
Step-by-step explanation:
The given information we know is..
- Kira is responsible for transporting 170 apples from a farm to the market.
- Each basket has a capacity of 46 apples.
We must divide 170 apples by 46 apples in order to solve this problem.
170/46 ( When I use the / symbol, it indicates to divide.)
170/46 = 3.69565217391
We'll have to round it up because we can't actually accept 3.69 bags. So the answer is 4 baskets.
Kira will need approximately 4 baskets.

Answer:
22x - 14
Step-by-step explanation:
pretty sure its like this..
3(4x-3)+5(2x-1)
= 3×4x + 3×(-3) + 5×2x + 5×(-1)
= 12x + (-9) + 10x + (-5)
and according to the rules of multiplying negative by positive...
= 12x - 9 + 10x - 5
combine like terms using the symbols on its left
= 12x + 10x - 9 - 5
= 22x - 14

take π to be 3.142 in your working.
Give your final answer to 1dp
Answer:
24.7
Step-by-step explanation:
Calculation of the area of the shaded sector is 24.7:
Since
Line PQ = 5.413590865cm
BQ = 9cm
Now
cos(x) = 0.8190928022
x = 35.00591739˚
Now finally the
Area of sector = 24.7cm^2
So point B is at the centre of the circle, making the area of the shaded sector to be 24.7 .

The first three terms of an arithmetic sequence are as follows.
Answer:
9, 3
Step-by-step explanation:
To get from 27 to 21, you subtract by 6. To get from 21 to 15, you must also subtract by 6. Therefore, subtracting by 6 is the pattern. In order to get the next number in the sequence, we must subtract 6 from 15.
15 - 6 = 9
The next number is 9. To find the number after 9, we must do the same thing - subtract 6 from 9.
9 - 6 = 3
The 5th number of the sequence is 3.

Answer:
102º
Step-by-step explanation:
So you know that ABC is an Isosceles triangle as AB=AC therefore, angle ABC is equal to angle ACB.
You also know that even though it doesn't look like it, ABP is an equilateral triangle as AB, AP and BP are equal so all those angles must equal 60º.
So:
ABC = 60 - 21 = 39º
and since ABC= ACB
ACB also equals 39º.
Because angles in a triangle add to 180º, BAC is consequently:
180- (39+39) = 180 - 78 = 102º
BAC = 102º
