The age of the older of two boys is twice that of the younger; 5 years ago it
was three times that of the younger. Find the age of each. pls include steps will mark brainiest
Answer: The older boy is now 20, the younger boy is now 10.
Step-by-step explanation: Explanation:
Let the age of the older boy now be y
let the age of the younger boy now be x
y = 2x
y-5 = 3(x-5)
simplifying
y = 3x - 10
substituting for y in equation 1
2x = 3x-10
simplifying
x = 10
substituting into 1
y = 20

There are seven dishes in total. Only one dish will be served at the venue and you can only have one top-ranked dish. Thus, there is a one in seven probability of your favorite dish is the one chosen to be served.
In a circle, what is the ratio of the circumference to its diameter?
area
radius
volume
PI
Answer:
D. pi
Step-by-step explanation:
Circumference of a circle = [tex] \pi d [/tex]
Diameter = d
Therefore, ratio of circumference of a circle to its diameter would be:
[tex] \pi d : d [/tex]
[tex] = \frac{\pi d}{d} = \pi [/tex] => (d cancels d)
Therefore, the ratio of the circumference of a circle to its diameter is [tex] \pi [/tex]
Anita opens a savings account by making a deposit of $272.95. Every week, she deposits another $45.25 in the account. How much will be in the account after 6 weeks?

Step-by-step explanation:
step 1:
6 x 45.25 = 271.5.
step 2:
271.5 + 272.95 = 544.45
Write the slope-intercept form of the equation of the line.
slope = 0, y - int=1
Answer:
y= 1
Step-by-step explanation:
This is because there will be no increase or decrease of x since we have no slope to take us there so it will remain constant at the y value

Solve the
equation:
-22 + x = 11
Answer:
[tex]x=33[/tex]
Step-by-step explanation:
Add 22 to both sides of the equation.
[tex]x=11+22[/tex]
Add 11 and 22.
[tex]x=33[/tex]
Answer:
x=33
Step-by-step explanation
Regroup terms.
x−22=11
Add 22 to both sides.
x=11+22
Simplify 11+22 to 33
ANDDDD the answer isss
x=33

5% of items in a large batch of items produced at a local foundry' are defective. If 50 of these items are selected at random, what is the probability that exactly 2 of the items will be defective? Round to four decimal places.
Answer:
0.2611
Step-by-step explanation:
We have x to be binomially distributed random variable which denotes the items number that are defective
We have been given n = 59 as our sample size
Probability of 5% = probability of success
1-5% = 0.95
We solve using this formula
nCxP^xq^n-x
= 50C2(0.05)²(0.95)^50-2
= 0.2611
This is the probability that exactly 2 would be defective

Which step in the solution contains the first error?
9514 1404 393
Answer:
Step 4
Step-by-step explanation:
In Step 1, the first equation is correctly multiplied by 2.
In Step 2, the two equations from step 1 are correctly added.
In Step 3, the value of x is correctly determined by dividing by 11.
In Step 4, the value of x is incorrectly substituted for y in the original first equation.
The first error is in Step 4.

Sue is upholstering a rectangular ottoman that measures 21 centimeters by 18 centimeters by 15 centimeters. What will be the total square centimeters of fabric that Sue must use to cover all faces of the ottoman?
Answer:
1926cm²
Step-by-step explanation:
Given
Dimension = 21cm by 18cn by 15cm
The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:
[tex]Surface\ Area =2(LB + LH + BH)[/tex]
Where L, B and H are the dimensions.
So,
[tex]Surface\ Area = 2(21 * 18 + 21 * 15 + 18 * 15)[/tex]
[tex]Surface\ Area = 2(378 + 315 + 270)[/tex]
[tex]Surface\ Area = 2(963)[/tex]
[tex]Surface\ Area = 2 * 963[/tex]
[tex]Surface\ Area = 1926cm\²[/tex]
Hence, 1926 cm² of fabrics are needed to cover all surfaces.
