Find the value of x so that the ratios 6 : x and 8 : 32 are equivalent.
Answer: The answer is 24
Step-by-step explanation:32/8 is 4. You just multiply 6 by 4.=24
Answer:
x = 24
Step-by-step explanation:
We require
[tex]\frac{6}{x}[/tex] = [tex]\frac{8}{32}[/tex] = [tex]\frac{1}{4}[/tex] ( cross- multiply )
x = 6 × 4 = 24

Paul was thinking of a number.Paul doubles it and gets a answer of 13.1.What was the orginal number?
Answer:
See below:
Step-by-step explanation:
So first, Paul has a number that he got before he multiplied it, we can call that [tex]p[/tex], and for his answer after doubling it. we'll call it [tex]n[/tex].
So with this information, we know that [tex]n=13.1[/tex] so we can use that to make an equation.
[tex]p*2=n\\p*2=13.1[/tex]
We can solve it by first dividing on both sides and getting our answer.
[tex]p=\frac{13.1}{2} \\p=6.55[/tex]
Cheers! We get our final answer of 6.55.
What percentage of goldfish will have lengths between 4. 6 inches and 9. 4 inches? 34% 68% 95% 99. 7%.
Using the Empirical Rule, it is found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
The Empirical Rule states that, for a normal variable:
Approximately 68% of the measures are within 1 standard deviation of the mean. Approximately 95% of the measures are within 2 standard deviations of the mean. Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem:
The mean is of 7 inches.The standard deviation is of 1.2 inches.4.6 = 7 - 2(1.2)
9.4 = 7 + 2(1.2)
Within 2 standard deviations of the mean, hence, 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

Determine the slope of the line represented by the equation 9x + 4y = 8. Represent the slope in decimal form.
Answer:
slope = - 2.25
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
9x + 4y = 8 ( subtract 9x from both sides )
4y = - 9x + 8 ( divide through by 4 )
y = - 2.25x+ 2 ← in slope- intercept form
with slope m = - 2.25

Nachelle wants to use a sheet of fiberboard 30 inches long to create a skateboard
ramp with a 19° angle of elevation from the ground. How high will the ramp rise from
the ground at its highest end? Round your answer to the nearest tenth of an inch if
necessary.
The height of the board is an illustration of Pythagoras theorem
The ramp will rise 10.3 inches from the ground
The angle of elevation is given as:
[tex]\mathbf{\theta = 19^o}[/tex]
The length of the board is given as:
[tex]\mathbf{l = 30}[/tex]
The height h is calculated using the following tangent ratio
[tex]\mathbf{tan(\theta) = \frac{Opposite}{Adjacent}}[/tex]
So, we have:
[tex]\mathbf{tan(19) = \frac{h}{l}}[/tex]
This gives
[tex]\mathbf{tan(19) = \frac{h}{30}}[/tex]
Make h the subject
[tex]\mathbf{h = 30 \times tan(19)}[/tex]
[tex]\mathbf{h = 10.3}[/tex]
Hence, the ramp will rise 10.3 inches from the ground

Solve for the measure of ∠PMR. Show your work and explain how you got your answer.
Answer:
61°
Step-by-step explanation:
We have to take the arcs at P to mean angles RPW and MPW are congruent. That means each is 58°/2 = 29°. Angle PMR is the other acute angle in right triangle PMW, so it will be the complement of 29°.
∠PMR = 90° -29° = 61°

What is the measure of angle L
Answer:
∠L=23°
Step-by-step explanation:
(6x-5)+(x+9)=(9x-24) (ext angle of triangle)
6x-5+x+9=9x-24
7x+4=9x-24
7x-9x=-24-4
-2x=-28
2x=28
x=28÷2
=14
Hence, ∠L = (x+9)°
= (14+9)°
= 23°

the admission fee at an amusement park is $3.50 for children and $7.20 for adults. on a certain day, 344 people entered the park, and the admissions fees collected totaled $1870. How many children and how many adults were admitted
Answer:
180 adults, 164 children
Step-by-step explanation:
Assuming all the people admitted are children,
total fees collected
= 344($3.50)
= $1204
Difference in amount collected
= $1870 -$1204
= $666
This difference in amount is due to the extra cost from each adult admission fee that we assumed to be children.
Difference in each admission fee
= $7.20 -$3.50
= $3.70
Number of adults admitted
= $666 ÷$3.70
= 180
Number of children admitted
= 344 -180
= 164

Answer is A
Step-by-step explanation:
find two numbers whose sum is 114 and the difference is 58.
(written as an equation please)
[tex]⇒[/tex]
x + y = 114
x - y = 58
Add the equations downward:
2x + 0y = 172
2x = 172
x = 86
x + y = 114
86 + y = 114
y = 114 - 86
y = 28

What percentage of a dollar is the value of 1 nickel and 3 pennies?
Answer:
8%
Step-by-step explanation:
1 dollar is 100 cents. 1 nickel and 3 pennies is 5+3 = 8 cents. 8 cents would be 8/100 = 8% of 100.
1 nickel and 3 pennies is 5.000000681 percent of a dollar.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
We know 1 nickels which is equal to 5 cents = 0.05 dollars.
1 penny = 0.00000000227 dollars
∴ 3 pennies is = 0.00000000681.
∴ 1 nickel and 3 pennies = 0.05000000681.
∴ 1 nickel and 3 pennies is (0.05000000681/1)×100% of a dollar.
= 5.000000681% of a dollar.
