Answer:
3 weeksStep-by-step explanation:
Step one:
given data
expected amount =$200
cash already at hand=$80
savings per week=$40
let the number of weeks be x
Step two:
the linear function for the situation is the same as the equation of a straight line
y=mx+c------1
200=4x+80
solve for x
200-80=40x
120=40x
divide both sides by 4
x=120/40
x= 3 weeks
Chandler will save for 3 weeks

the height of an apple
Answer:
apples are usually roundish, 5–10 cm (2–4 inches) in diameter
Step-by-step explanation:
Dwarf apple trees grow about 10 feet tall, while semi-dwarf varieties can reach 15 feet. Meanwhile, standard-size apple trees often soar to heights above 20 feet and sometimes tower at 30 feet.
Apples are 5 - 10 cm in height.
What is height?Height, altitude, elevation mean vertical distance either between the top and bottom of something or between a base and something above it
Given is an apple.
When harvested, apples are usually roundish, 5–10 cm (2–4 inches) in diameter.
Therefore, apples are 5 - 10 cm in height.

Help please! The division Axiom would allow us to say which two angles are equal?
Answer:
The correct option is;
(3) ∠ADB and ∠BDC
Step-by-step explanation:
From the division axiom, we have;
(a+a)/a = 2·a/a = 2
The given parameters are;
m∠ADC = m∠ABC
[tex]\overline {BD}[/tex] bisects ∠ADC and ∠ABC
Therefore;
∠ADB ≅ ∠BDC
∠ABD ≅ ∠CBD
Therefore;
∠ADB/∠CBD = ∠BDC/∠ABD
Given that m∠ADC = m∠ABC and ∠CBD = 1/2 × m∠ABC = 1/2 × m∠ADC = ∠ABD, we are allowed to say, ∠ADB and ∠BDC are equal.

What value of x is in the solution set of 9(2x + 1) < 9x – 18?
Answer:
-3 > x
Step-by-step explanation:
Multiply 2x and 1 by 9. You have 18x + 9 < 9x - 18.Add 18 to 9. You are adding because it is the opposite of subtraction, so it cancels out. You now have 18x + 27 < 9x.Subtract 18x from 9. There is no addition sign in front of the 18x, but it's basically implied. You now have 27 < -9x.Divide both sides by -9. When you divide by a negative, the inequality sign flips. You now have -3 > x.8 divided by 32.16?

Answer:
Solving equation [tex]13-715x=130x[/tex] we get [tex]x= \frac{1}{65}[/tex]
Step-by-step explanation:
We need to solve the equation [tex]13-715x=130x[/tex]
Combining like terms and solving
[tex]13-715x=130x\\Adding \ 715x \ on \ both \ sides:\\13-715x+715x=130x+715x\\13=845x\\Divide \ both \ sides \ by \ 845\\\frac{13}{845}=\frac{845x}{845}\\=>x= \frac{1}{65}[/tex]
So, solving equation [tex]13-715x=130x[/tex] we get [tex]x= \frac{1}{65}[/tex]

In 2014, 85 percent of households in the United States had a computer. For a randomly selected sample of 200 households in 2014, let the random variable C represent the number of households in the sample that had a computer. What are the mean and standard deviation of C ?
Answer:
The mean of C is 170 households
The standard deviation of C, is approximately 5 households
Step-by-step explanation:
The given parameters are;
The percentage of households in the United States that had a computer in 2014 = 85%
The size of the randomly selected sample in 2014, n = 200
The random variable representing the number of households that had a computer = C
Therefore, we have;
The probability of a household having a computer P = 85/100 = 0.85
Let
Therefore;
The mean (expected) number in the sample, μₓ, = E(x) = n × P is given as follows;
μₓ = 200 × 0.85 = 170
The mean of C = μₓ = 170
The variance, σ² = n × P × (1 - P) = 200 × 0.85 × (1 - 0.85) = 25.5
Therefore;
The standard deviation, σ = √(σ²) = √(25.5) ≈ 5.05
The standard deviation of C, σ ≈ 5 households (we round (down) to the nearest whole number)
The mean and the standard deviation of C are 170 and 5.05 respectively
The given parameters are:
[tex]\mathbf{n = 200}[/tex] -- the sample size
[tex]\mathbf{p = 85\%}[/tex] -- the proportion of household that had a computer
(a) The mean
This is calculated as:
[tex]\mathbf{\bar x = np}[/tex]
So, we have:
[tex]\mathbf{\bar x = 200 \times 85\%}[/tex]
[tex]\mathbf{\bar x = 170}[/tex]
(b) The standard deviation
This is calculated as:
[tex]\mathbf{\sigma = \sqrt{np(1 - p)}}[/tex]
So, we have:
[tex]\mathbf{\sigma = \sqrt{170 \times (1 - 85\%)}}[/tex]
[tex]\mathbf{\sigma = \sqrt{170 \times 15\%}}[/tex]
[tex]\mathbf{\sigma = \sqrt{25.5}}[/tex]
Take square roots
[tex]\mathbf{\sigma = 5.05}[/tex]
Hence, the mean and the standard deviation of C are 170 and 5.05 respectively

Jackson kitten weighed 2 pounds 3 ounces a month later the kitten weighed 56 ounces. How munch weight did the kitten gain in that month. How many ounces did the kitten gain
Answer: 21 ounces
Step-by-step explanation:
From the question, we are told that Jackson kitten weighed 2 pounds 3 ounces a month. We should note that 16 ounces = 1 pound.
Therefore we'll convert 2 pounds, 3 ounces to ounces. This will be:
= (2 × 16 ounces) + 3 ounces
= 32 ounces + 3 ounces
= 35 ounces
We are further told that later the kitten weighed 56 ounces.
The amount of weight gained by the kitten in that month will be:
= 56 ounces - 35 ounces
= 21 ounces

What are the coordinates of point S”?
Answer:A
Step-by-step explanation:
Mr. Au went to eat at McDonald's this week. On Monday, he ate some hamburgers. On Tuesday, he ate nothing at McDonald's. On Wednesday, he ate four more hamburgers than the number that he ate on Monday. On Thursday, he ate nothing at McDonald's. On Friday, Mr. Au ate three times as many hamburgers as he ate on Wednesday. Mr. Au ate a total of 26 hamburgers that week. How many hamburgers did he eat each day?
Answer: See explanation
Step-by-step explanation:
Let the number of hamburger he ate on Monday be represented by x.
Monday = x
Tuesday = 0
Wednesday = x + 4
Thursday = 0
Friday = 3(x + 4)
Total hamburgers ate = 26
To find the amount of hamburger ate each day we add the number of hamburger ate per day all together. This will be:
= x + 0 + x + 4 + 0 + 3(x+4) = 26
2x + 4 + 3x + 12 = 26
5x + 16 = 26
5x = 26 - 16
5x = 10
x = 10/5
x = 2
Monday = x = 2 hamburgers
Tuesday = 0
Wednesday = x + 4 = 2 + 4 = 6 hamburgers
Thursday = 0
Friday = 3(x + 4) = 3(2 + 4) = 18 hamburgers

6x + 3x - x + 9 = 33
Answer: x=3
Step-by-step explanation:
6x + 3x - x + 9 = 33
Combine like terms:
6x+3x-x=8x
The equation is now 8x+9=33
Subtract 9 on both sides:
8x+9-9=33-9
8x=24
Divide 8 on both sides:
8x/8=24/8

− 3/4 is a rational number, but not an integer. Explain why below.
− 3/4 is not an integer but a a rational number.
Why is this correct?A rational number is simply a number that can be written as a fraction with both the numerator and denominator being integers (where the denominator's not zero). For instance lets consider 3/4 as an example. It can be expressed as the fraction 3/4, where 3 and 4 are both integers.
On the hand an integer is a number that is not, in the form of a fraction. In the case of 3/4 it cannot be classified as an integer since it represents a fraction, than a whole number.

Answer:
Vertical angles are always congruent, or of equal measure. ... Both pairs of vertical angles (four angles altogether) always sum to a full angle (360°). Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees. so therefore verticle angles DO NOT form a linear pair
