Answer:
7.3 or 7 hours.
Step-by-step explanation:
So i divided 58.4 by 8. And got 7.3.
8 x (7) = 56. So, 58 - 56 = 2. Put the decimal up. Now, 8 x (3) = 24. So, now you should have 7.3. But you could round it to 7. Depends.

77 is what percent of 192
in this condition "of" is considered as multiply(×) so the questions form in maths form is 77% × 192
because it is multiplication sign we multiply 77×192=14784 dont forget the percentage % percent is /100 so 14784/100 = 147.84.
Customers at a yogurt shop took a survey. The results showed that 162 customers rated the shop as being "very aatisfactory". The number represented 45 of the total numbee of customers who took the survey. What was the total number of customers who took the survey?
Answer: 360 people
Step-by-step explanation:
162 people who took the survey represented 45% of the total participants.
Assume the total participants is x.
The expression would be;
162 = 45% * x
x = 162/45%
x = 360 people

If ABCD is dilated by a factor of 2 the coordinate of b would be? Will mark barinlyist.
Answer:
B'(- 2, 2 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is
B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )

Jazmine can run 4 5/6 miles in 2/3 of an hour. How many miles can she run in 1 hour?
Answer: she can run [tex]6\dfrac54[/tex] mile sin 1 hour.
Step-by-step explanation:
Given : Distance run by Jasmine in [tex]\dfrac23[/tex] of an hour = [tex]4\dfrac56\text{ miles}=\dfrac{24+5}{6}\text{ miles}[/tex]
[tex]=\dfrac{29}{6}[/tex] miles
Distance run by Jasmine in 1 hour = [tex]\dfrac{29}{6}\times\dfrac{3}{2}=\dfrac{29}{4}[/tex] miles.
[tex]=6\dfrac{5}{4}[/tex] miles.
Hence, she can run [tex]6\dfrac54[/tex] mile sin 1 hour.

A funnel is shaped like a cone and is 4.5 inches high and has a diameter of 6 inches. What is the volume of the funnel? Use 3.14 for pi Round your answer to the nearest hundredth
Answer:
Step-by-step explanation:
V = 1/3 pi r^2 h
r = d/2
r = 6/2 = 3
h = 4.5
V = 1/3 *3.14 * 3^2 * 4.5
V = 1/3 * 3.14 * 9 * 4.5
V = 1/3 * 127.17
V = 42.39

Given the function f(x) = 2-4, determine the slope of the tangent line of f at
x = -1 using the limit shown below. You do not have to simplify your answer.
Answer:
Slope of the tangent line at x=-1
[tex](\frac{dy}{dx})_{x=-1} = e^{-5}[/tex]
Step-by-step explanation:
Explanation:-
Given function
y = f(x) = e ˣ⁻⁴ ...(i)
Differentiating equation (i) with respective to 'x' , we get
[tex]\frac{dy}{dx} = e^{x-4} \frac{d}{dx} (x-4)[/tex]
[tex]\frac{dy}{dx} = e^{x-4} (1)[/tex]
Slope of the tangent line
[tex](\frac{dy}{dx})_{x=-1} = e^{-1-4} = e^{-5}[/tex]

A half marathon is around 13 miles. Brian can run about 6 1⁄3 miles per hour. If Brian keeps his pace, how long will it take him to run a half marathon?
Answer:
2.053 hours
Step-by-step explanation:
From the question,
A half marathon is around 13 miles. Brian can run about 6 1⁄3 miles per hour.
If Brian keeps his pace, how long will it take him to run a half marathon?
This is calculated as:
6 1/3 miles = 1 hour
13 miles = x hour
Cross Multiply
6 1/3 miles × x hour = 13 miles × 1 hour
x hour = 13 miles × 1 hour/6 1/3 miles
x hour = 13 ÷ 6 1/3 miles
x hour = 13 ÷ 19/3
x hour = 13 × 3/19
x hour = 39/19
x hour = 2.0526315789 hours
Approximately = 2.053 hours
It will take him 2.053 hours to run a half marathon.
marla has 4.55 in dimes and quarters. if she ha s7 more quarters than dimes, how many quarters doe she have?
Answer:
number of dimes is 8
number of quarters is 15
Step-by-step explanation:
let 'd' = number of dimes
let 'd+7' = number of quarters
.10d + .25(d + 7) = 4.55
.10d + .25d + 1.75 = 4.55
.35d = 2.80
d = 8
q = 7 + 8

Hello!
[tex]\large\boxed{x = 4.21in}[/tex]
Use the Pythagorean Theorem to solve:
a² + b² = c²
We are given the Hypotenuse (c) and one of the legs (b), so we can plug those values in to solve for a:
a² + (6.8)² = 8²
a² + 46.24 = 64
Subtract 46.24 from both sides:
a² = 17.76
Square root both sides:
a = √17.76
a ≈ 4.21 = x

You spend c dollars for p identical pairs of pants. A friend claims that because c increases if you increase p and p increases if you increase c either c or p could be the independent variable. Is your friend right or wrong? Explain.
Answer:
Your friend is wrong.
Step-by-step explanation:
Since we have that you spend c dollars for p identical pairs of pants. We can represent this using:
C = kP.
Where k is the price for one pair of pants whereby the amount of dollars you spend depends on the number of pants picked.
C is the dependent variable here, depending on P and P is independent. Therefore, you have only one independent variable which is P.
