Answer:
Rida is 10 years old and her father is 40 years old.
Step-by-step explanation:
Given:
Present age
Present age of Rida = x
Present age of Rida's father = 4x
Age after 5 years
Age of Radi after 5 years = x + 5
Age of Radi's father after 5 years = 3(x + 5)
What To Find:
The present age of Rida and Rida's father.
Solution:
According to the statement the equation will be,
⇒ 4x + 5 = 3(x + 5)
Remove and solve the brackets,
⇒ 4x + 5 = 3x + 15
Take numbers to RHS and variable to LHS,
⇒ 4x - 3x = 15 - 5
Subtract 3x from 4x and 5 from 15,
⇒ x = 10
Now substitute the values of Rida's age and Rida's father's age,
Rida's age = x = 10 years
Rida's father's age = 4x = 4(10) = 40 years

Answer:
x = 7
Step-by-step explanation:
The larger triangle is twice as big as the smaller triangle. Therefore, the length of the side EF is twice as large as the side YZ.
I multiplied 4.5 (the length of YZ) and 2 to get 9. The value of side EF is 3x-12 and should be equivalent to 9.
3x - 12 = 9
I solved this equation by adding 12 to both sides and dividing 3 on both sides.
The value of x is 7.
Find the volume of the sphere.
Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.
Answer:
Volume of a sphere = 4πr³/3
r=10
V = 4πx10³/3
=4000π/3
V= 1333.33π (in terms of pi)
or
V= 4188.79(Nearest Hundredth).

======================================================
Explanation:
The numbers up top are 1,1,1. They multiply to 1*1*1 = 1. So that means 1 is the numerator of the answer.
The numbers down below are 6,2,3. They multiply to 6*2*3 = 36. This is in the denominator for the answer.
That means (1/6)*(1/2)*(1/3) = 1/36
The rule I used is (a/b)*(c/d) = (a*c)/(b*d)
Answer:
1/36
Step-by-step explanation:
Step 1:
1/6 · 1/2 · 1/3 Equation
Step 2:

For each part below use the figure to fill in the blank if necessary you may learn what the markings on a figure indicate PLZ HELP I WILL MARK BRAINLIEST
Answer:
60˚, 75˚
Step-by-step explanation:
for part a:
since all sides are the same length (represented by the 3 same type of tick marks on all sides) then the triangle is equilaterial. Which means all the angles are the same.
Sum of angles in a triangle is 180˚.
x represents the value of <N, <M, and <P
so since all angles are the same, 3x = 180, all angles of part a triangle are 60˚. Therefore, <M is 60˚.
for part b:
this is an isoceles triangle since two sides are the same length.
If it's isoceles, that means it's 2 base angles are the same value.
We've already been given the vertex angle.
x represents the value of <S and <Q
2x + 30 = 180.

Answer:
Step-by-step explanation:
A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an inequality as x+2x+6<50, where xrepresents the smaller number.
From the set (13, 14, 15, 16, 17), the values of x for which the inequality holds true are
Answer:
13, 14
Step-by-step explanation:
The parameters of the numbers are;
A whole number value = 2 × Another number + 6
The sum of the two numbers is less than 50
Given that the first number is equal to more than twice the second number, we have that the first number is the larger number, while the second number is the smaller number
Where 'x' represents the second number, we get;
x + 2·x + 6 < 50
Simplifying gives;
3·x + 6 < 50
x < (50 - 6)/3 = 14.[tex]\overline 6[/tex]
x < 14.[tex]\overline 6[/tex]
Therefore, the numbers for which the inequality holds true are numbers less than 14.[tex]\overline 6[/tex]. From the given option, the numbers are 13, and 14.
PLZ HELP: Write the inverse function for the function, ƒ(x) = 1/2x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.
Answer:
see explanation
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = [tex]\frac{1}{2}[/tex] x + 4 ( multiply through by 2 to clear the fraction )
2y = x + 8 ( subtract 8 from both sides )
2y - 8 = x
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex](x ) = 2x - 8
[tex]f^{-1}[/tex](4) = 2(4) - 8 = 8 - 8 = 0

A shoe store sends an email survey to all customers who pay with a debit card. The previous month, 34,000 people made debit card purchases. Surveys were sent to 2,000 of these people, chosen at random, and 256 people responded to the survey. Identify the population and the sample. The population is 34,000. The sample is 2,000. The population is 2,000. The sample is 256. The population is 256. The sample is 34,000. The population is 2,000. The sample is 34,000. The population is 34,000. The sample is 256.
Answer:
The population is 34,000. The sample is 2,000
Step-by-step explanation:
Population in statistics can be explained as the group or set of all elements which are of particular interest to a researcher or a study. In the scenario above, the research interest concerns customers who pay with a debit card, whose number amounts to 34,000, this value refers to the population. The sample is referred to as the subset of the population or larger sample, the sample from the study corresponds to number of debit card users who were selected at random to participate in the survey. This value is 2000.

Answer:
32 degrees.
Step-by-step explanation:
A triangle is 180 degrees.
180 - 85 - 63 = 32 degrees.
Answer:
x = 32
Step-by-step explanation:
All interior angles in a triangle equal to 180
use this to solve for x
180 = 85 + 63 + x
180 - 85 - 63 = x
32 = x
What are the domain and range of the function represented by the table?
Answer:
Doman is always the x-intercept.
And Range is always the y-intercept.
Domain = {-5, 0, 5, 10, 15}
Range = {-1, 0, 1, 2, 3}
So the answer is C.
