If 15% of x is 42, what is x?
The required whole value of x is 280 if 15% of x is 42.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.
To determine the value of x, we can set up the equation: (15/100)x = 42.
This equation states that 15% of x is equal to 42.
To solve for x, we can divide both sides of the equation by (15/100) to get:
x = (100/15) × 42
x = 280
So x = 280.
This means that if 15% of x is 42, then the whole value of x is 280.

Answer:
7.63 ounces of strawberries + 5.26 ounces of blueberries
7.63 + 5.26= 12.89 - 1.37 left over = 11.52 to be split between 2 bowls equally
11.52/2 = 5.76 per bowl
5.76 ounces of fruit in each bowl.
What is mathematical expression?
A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given,
strawberries = 7.63 ounces
blueberries = 5.26 ounces
Put the fruits into two equal bowls in equal amounts
let the amount be x
remaining amount = 1.37 ounces
According to the statements, we can state that,
2x + 1.37 = 7.63 + 5.26
2x = 11.52
x = 5.76
Therefore, the two bowl contains 5.76 ounces of fruit each.

Step-by-step explanation:
Irving lives in Appletown, and plans to drive along Highway 42, a straight highway that leads to Bananatown, located 143 miles east and 45 miles north. Carol lives in Coconutville, located 98 miles east and 32 miles south of Appletown. Highway 86 runs directly north from Coconutville, and junctions with Highway 42 before heading further north to Durianville. Carol and Irving are planning to meet up at park-and-ride at the junction of the highways and carpool to Bananatown. Irving leaves Appletown at 8am, driving his usual 45 miles per hour. If Carol leaves Coconutville at 9am, how fast will she need to drive to arrive at the park-and-ride the same time as Irving?
Answer:
The speed at which Carol needs to drive to meet Irvin at Bananatown at exactly the same time is approximately 47.188 miles per hour
Step-by-step explanation:
The given information are;
The location of Bananatown from Appletown = 143 miles east and 45 miles north
The location of Coconutville from Appletown = 98 miles east and 32 miles south
Taking Appletown as the origin, we have;
The slope, gradient of highway 42 = 45/143
The equation of a line representing highway 42 is given as follows;
y - 0 = 45/143 × (x - 0)
y = 45/143·x
Therefore, at Coconutville, where x = 98, we have, y = 45/143 × 98 ≈ 30.84 miles north
Total distance north Carol has to drive to get to highway 42 = 32 + 30.84 = 62.84 miles
Total distance along highway 42 Carol will drive to get to Bananatown = √((143 - 98)² + (45 - 30.84)²) ≈ 47.175 miles
Total distance Carol drives to Bananatown = 47.175 miles + 62.84 miles ≈ 110.015 miles
The total distance Irvin needs to drive to arrive at Bananatown = √(143² + 45²) ≈ 149.91
The total distance Irvin needs to drive to arrive at Bananatown ≈ 149.91 miles
The time it takes Irvin to arrive at Bananatown = (149.91 miles)/(45 mph) ≈ 3.33 hours
The time he arrives at Bananatown = 8 a.m. + 3.33 hours ≈ 11.33 a.m.
The time available for Carol to meet Irvin at Bananatown at exactly the same time = 11.33 a.m. - 9 a.m. = 2.33 hours
Therefore, the speed at which Carol needs to drive = (110.015 miles)/2.33 hour ≈ 47.188 miles per hour
The speed at which Carol needs to drive to meet Irvin at Bananatown at exactly the same time ≈ 47.188 miles per hour.

1. What is the wavelength of a radio wave broadcast at 150 MHz?
The value of the wavelength will be equal to 2 meters.
It is given that a radio is broadcasting at 150 MHz .
We have to calculate the wavelength.
What is the formula for wavelength ?
The wavelength is given by L = c/f , where c = speed of wave and f is the frequency of wave.
∵ L = c/f
Let's assume c = 3 × 10^8
Given that frequency (f) is 150 MHz .
Wavelength (L) is approximately ;
L= (3 × 10^8 )/ (150,000,000)
L= 2 meters
Thus, the wavelength of a radio wave broadcast at 150 MHz will be equal to 2 meters.

How would you write 0.5.... as a decimal?

Fraction: 1/2

Step-by-step explanation:
The county fair charges $3.25 per ticket for the rides. Henry bought 8 tickets for the rides and spent a total of $39.50 at the fair. Henry spent his money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Use x to represent the number of ride tickets and y to represent the total cost.
(a) Find the cost of admission to the fair. Explain how you found the cost of admission.
(b) Write a linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission.
(c) Explain what the coefficient on x and the constant of your linear equation represent.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Cost per ticket = $3.25
Number of ride tickets purchased (x) = 8
Total amount spent at the fair (y) = $39.50
Henry's spending was only on ticket rides and fair admission
a) Find the cost of admission to the fair. Explain how you found the cost of admission.
Total spending = amount spent on ticket rides + cost of admission to fair
$39.50 = 8(3.25) + cost of admission
39.50 = 26 + cost of admission
Cost of admission = (39.50 - 26) = $13.50
(b) Write a linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission.
Since cost of admission is the same for everyone :
Total cost = 3.25x + 13.50
y = 3.25x + 13.50
(c) Explain what the coefficient on x and the constant of your linear equation represent.
3.25 = cost per ride ticket
13.50 = cost of admission to fair

Answer:
a. f(1) = -4
b. One value of x for which f(x) = -1 : 2 (or -2)
Step-by-step explanation:
a. To find f(1), we would have to find what the value of the function would be when x = 1. By using the given graph, we can find the f(1) by finding what the y-value is when x = 1. Looking at the graph, we can see that when x = 1, y = -4. Thus, f(1) = - 4.
b. Now we are also asked to find one value of x for which f(x) = -1. In other words, what values of x would make the value of the function equal to -1? We can find values of x for which f(x) = -1 by using the graph and seeing for which x-values would the y-value be -1. We can see that y = -1 at x = -2 and x = 2. So the values of x at which f(x) = -1 are -2 and 2. You can choose either one of these values.

Quest 6. let No. of cells = Nc, let No. of Hours = Nh.
then Nc = (6hrs x 2cells)/1hr = 12 cells.
if 1,024 cells, then
Nh = (1hrs x 1,024cells)/2hrs = 512 hrs.
Quest 7. No, cos 10^7 is only 10,000,000, so 39 & 10 million are not any way equal.
Quest 8. 1 = 1^3, 8 = 2^3, 27 = 3^3, 1 = 1^3, 64 = 4^3, 125 = 5^3,
Quest 9. 2^8 = 2 x 2 x 2 x 2 x 16 = 256, this cos 256 is a product of 8, 2s & there are 4, 2s in 16.
so altogether its all 8, 2s.
Kelly purchased 6 equally-priced CDs for a total of $75.30 what is the cost per CD?
Answer:
$12.55 per CD
Step-by-step explanation:
If each CD is of equal price, you must then divide the price by the number of CD's. (75.30/6=12.55)
Answer:
$75.30/6 = $12.55 per CD
Step-by-step explanation:
Since the CDs are equally-priced, my thought is that you would divided the quantity that you purchased by your total to get your answer. So, your total, $75.30 divided by, the amount of CDs purchased, 6. This would lead you to the answer $12.55, which is the cost of each CD. To check your answer you would multiply $12.55 by 6 to get $75.30.
