Dhanraj spent $204.20 purchasing volleyballs and basketballs.
He bought 3 more basketballs than volleyballs. If each volleyball cost $8.20 and each basketball cost $12.60, how many of each type did he buy?
Answer:
Number of volleyballs bought = 8
Number of basketballs bought = 11
Step-by-step explanation:
Given that:
Total amount spent = $204.20
Let,
x be the number of volleyballs
y be the number of basketballs
According to given statement;
y = x+3 Eqn 1
8.20x+12.60y=204.20 Eqn 2
Putting value of y from Eqn 1 in Eqn 2
8.20x + 12.60(x+3) = 204.20
8.20x + 12.60x + 37.80 = 204.20
20.80x = 204.20 - 37.80
20.80x = 166.40
Dividing both sides by 20.80
[tex]\frac{20.80x}{20.80}=\frac{166.40}{20.80}\\x=8[/tex]
Putting x=8 in Eqn 1
y = 8+3 = 11
Hence,
Number of volleyballs bought = 8
Number of basketballs bought = 11

write 5.3 x 5.3 x 5.3 x 5.3 as a power.
I need an answer, please. thanks. -Furreto
Answer:
5.3 to the 3rd power
Step-by-step explanation:
The expression 5.3 x 5.3 x 5.3 x 5.3 can be expressed as (5.3)⁴.
To express 5.3 x 5.3 x 5.3 x 5.3 as a power, we can use the exponentiation property.
When we multiply a number by itself multiple times, we can simplify it using an exponent.
In this case, we have four instances of multiplying 5.3 by itself. So we can write it as:
5.3 x 5.3 x 5.3 x 5.3 = (5.3)⁴
The exponent 4 indicates that we are multiplying 5.3 by itself four times.
It represents the number of times the base (5.3) is multiplied by itself.
So, (5.3)⁴ means 5.3 raised to the power of 4, which is equivalent to multiplying 5.3 by itself four times.
Therefore, 5.3 x 5.3 x 5.3 x 5.3 can be expressed as (5.3)⁴.

Find the inverse of f (x) = x + 2 + 9
Answer:
y = x - 11
Step-by-step explanation:
First, turn the f(x) into a y:
y = x + 2 + 9
Now, switch the x and y.
x = y + 2 + 9
Add like terms.
2 + 9 = 11
x = y + 11
Now, solve for y. Subtract 11 on both sides.
y = x - 11

Bill drove 240 miles in 4 hours. On another day, he drove 480 miles in 8 hours. What is the constant of proportionality?
Answer:
12
Step-by-step explanation:
This is a fraction equal to
30 miles ÷ 2.5 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2.5
30 miles ÷ 2.5
2.5 hours ÷ 2.5
=
12 miles
1 hour
=
12 miles
hour
= 12 miles per hour

A recipe for pie dough calls for a ratio of butter to flour of 23 : 134. If you plan to use 7 cups of flour, how much butter should you use to keep the same ratio?
Answer:
You might have to round, but ≈1.2015
Step-by-step explanation:
butter: flour
23 : 134 is really just a:b
b = 7, so: a : 7
Divide both sides by 134, so
≈0.172 : 1
Multiply by 7 to get 7 cups of flour
≈1.2:7

Answer:
Part A: it is linear because it is not curving and it consists of straight lines.
Part B: in side A it is increasing because it has a positive slope. In side b it is constant because the slope is 0 since it is straight. Finally, side C is decreasing because the slope is negative.
Part C: during side A the ant is crawling out of the hole in 2 seconds. After that, the ant stops for 2 more seconds as shown in side B. Then, he crawls back into the hole as shown by the decrease in distance due to the slope.

A 3-foot-wide wood deck will be built around a rectangular-shaped pool that measures 15 feet by 30 feet. The resulting shape is also rectangular. If the lumber costs $10 per square yard, If the lumber costs 10 dollars per square yard, what is the cost of the wood for the deck?
Answer:
$340
Step-by-step explanation:
We are told that the pool measures 15 feet by 30 feet,
Since the cost of the wood around it is per yards, let's convert this measurement to yards.
15 ft = 5 yards
30 ft = 10 yards
The deck is 3 ft wide. Converting to yards it is 1 yard.
Since the deck is round the pool, it means when we add it to the pool dimensions, we now have a dimension of; width: 7 yards by length: 12 yards
Thus, total area of pool and deck is;
A_t = 7 × 12 = 84 Sq.yds
Area of only pool is;
A_p = 5 × 10 = 50 Sq.yds
Finally, area of the deck will be;
A_d = 84 Sq.yds - 50 Sq.yds = 34 Sq.yds
We are told that the costs of the wood is $10 per Sq.yds
Thus, total cost is;
C = 10 × 34
C = $340

7 one is equivalent to how many hundreds?
1400 tenths is equivalent to how many tens?
Answer:
(i) 7 one is equivalent is equivalent to [tex]\frac{7}{100}[/tex] hundreds, (ii) 1400 tenths is equivalent to 14 tens.
Step-by-step explanation:
We proceed to find the equivalent number in rational form:
(i) 7 one is equivalent to how many hundreds? In this case, we know that 7 one is equivalent to [tex]x[/tex] hundreds. That is:
[tex]7\times 1 = x \times 100[/tex]
Then, we solve the expression for [tex]x[/tex]:
[tex]x = \frac{7\times 1}{100}[/tex]
[tex]x = \frac{7}{100}[/tex]
7 one is equivalent is equivalent to [tex]\frac{7}{100}[/tex] hundreds.
(ii) 1400 tenths is equivalent to how many tens? In this case, 1400 tenths is equivalent to [tex]x[/tex] tens. That is:
[tex]1400\times \frac{1}{10} = x\times 10[/tex]
Then, we solve for [tex]x[/tex]:
[tex]x = \frac{1400}{10\times 10}[/tex]
[tex]x = \frac{1400}{100}[/tex]
[tex]x = 14[/tex]
1400 tenths is equivalent to 14 tens.

What is the cosine law?The squared of the size of any solitary side of either a triangle is equal, by the cosine rule, to the total of the squares of the lengths of the other two sides, times by the cosine of something like the angle they are a part of.
Let the triangle ΔABC, then the cosine law is given as,
c² = a² + b² - 2 a·b cos C
From the graph, the measure of the length 'x' is calculated as,
x² = 5² + 8² - 2 (5)·(8) cos 55°

A dilation will always produce similar figures. Therefore, option C is the correct answer.
We need to find the which is a true statement about dilation.
What is a dilation?Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape. But there is a difference in the size of the shape.
After the dilations an image and original shape look same, so they are similar.
A dilation will always produce similar figures. Therefore, option C is the correct answer.
