Answer:
The two siblings will have saved the same amount towards their mother's gift after 3 weeks.
Amount saved by Wyatt = [tex]\$41[/tex]
Amount saved by Wyatt's sister = [tex]\$41[/tex]
Step-by-step explanation:
Let [tex]t[/tex] (in weeks) denotes the time period by which the two siblings will have saved the same amount towards their mother's gift.
Wyatt already has $20 saved and plans to save $7 per week from his allowance.
Amount saved by Wyatt = [tex]20+7t[/tex]
Wyatt's sister has $14 saved so far and will save $9 per week from hers.
Amount saved by Wyatt's sister = [tex]14+9t[/tex]
To find the time period by which the two siblings will have saved the same amount towards their mother's gift,
solve the following equation.
[tex]20+7t=14+9t\\20-14=9t-7t\\6=2t\\3=t[/tex]
So, the two siblings will have saved the same amount towards their mother's gift after 3 weeks.
Amount saved by Wyatt = [tex]20+7(3)=20+21=\$41[/tex]
Amount saved by Wyatt's sister = [tex]14+9(3)=14+27=\$41[/tex]
What is the value of x?
Answer:
I have no idea. But I just want to let you know to not put this many points, because people are going to take them without answering the question. And I don't know the answer because there are multiple x's.
Answer:
x = 8
Step-by-step explanation:
Remark
I agree with the other responder. You need only pay 20 points to get our attention. (20 will give us 10).
The length from the intersect point to the circle times the entire length of the secant is equal to any other secant divided up the same way.
Put simpler
Equation
(x + 2)(x + 2 + 2x- 8) = (x + 1)(x + 1 + 2x - 5)
Combine like terms
Solution
(x + 2)(3x - 6) = (x + 1)(3x - 4) Remove the brackets on both sides.
3x^2 + 6x - 6x - 12 = 3x^2 + 3x - 4x - 4 Combine the like terms
3x^2 - 12 = 3x^2 - x - 4 Subtract 3x^2 from both sides
- 12 = - x - 4 Add 4 to both sides
-12 +4 = - x
- 8 = - x Multiply both sides by -1
x = 8
The cube has a side length of 2 3/4*
Find the lateral surface
area of the cube
Step-by-step explanation:
The cube have 6 sides.
The 2 sides are base surface and the other 4 are lateral surface.
A=4L
4A=4❨4L)
4A=16L
4A=16(2 3/4)
4A=16(11/4)
4A=4(11)
4A=44
so the lateral surface is 44
A die is rolled 3. What is the probability of getting a 1 on the first roll, a 2 on the second roll, and a 3 on the third roll
Answer:
The probability of getting 1,2 and 3 after rolling once , second and thrice is
1/6
Step-by-step explanation:
These are all independent events.
The sample space = [1,2,3,4,5,6]
A die has 6 sides
1. If this die is thrown once, the probability of getting a 1 is = 1/6
2. If we roll the dice a second time, the probability of getting a 2 is independent from the first time it was rolled, so the sample space remains the same. The probability is also 1/6
3. If we rolled a 3rd time the probability remains 1/6 also

Answer:
c = 74
d = 122
a = 58
b = 48
Step-by-step explanation:
C: a triangle always equals to 180, so 48 + 58 - 180 = 74
D: Angels next to each other on a line always equal to 180, so 180 - 58 = 122
A: Alternating interior angles of a parallel line equal to each other, so it would also be 58
B: A line is 180, so C + A - 180 = B, 74 + 58 - 180 = 48

What is the solution to the equation 38.18 + x = 82.06? A. 44.88 B. 43.88 C. 56.12 D. 44.12
Answer:
A
Step-by-step explanation:
Simplify both sides x+38.18=82.06
subtract 38.18 from both sides
x+38.18-38.18=82.06-38.08
x=43.88

What is the y-intercept of each graph?
Explain.
Answer:
Step-by-step explanation:
The intercepts of a graph are points at which the graph crosses the axes. The x-intercept is the point at which the graph crosses the x- axis. At this point, the y- coordinate is zero. The y-intercept is the point at which the graph crosses the y- axis. At this point, the x- coordinate is zero.
3 boys shared a box of chocolate. The first boy got 3/8 of the total and the 2nd boy got 2/5 of the remainder and the 3rd boy got 9. How many chocolates were in the box and how many did the boy with the smallest share get?
Answer:
1. there were 24 chocolates in the box at first.
2. the boy with the smallest share received 6 chocolates.
Explanation:
let's represent the number of chocolates in the box with 8x.
the first boy got ⅜ × 8x = 3x chocolates. now, there are 8x - 3x = 5x chocolates remaining.
the second boy got ⅖ × 5x = 2x chocolates. now, there are 5x - 2x = 3x chocolates remaining.
3x = 9 chocolates
x = 3 chocolates
since the original number of chocolates was represented by 8x, we now know that there were 8 × 3 = 24 chocolates in the box at first.
the first boy got 9 chocolates, the second boy got 6 chocolates and the last boy got 9 chocolates. thus, the boy with the smallest share got 6 chocolates.

Answer:
44ft
Step-by-step explanation:
The formula for circumference is 2 * π * radius and in this case we want to use 3.14 for π and so we do 2 x 3.14 x 7 because the radius is half of the diameter (14) and once you do that you end up getting 43.96 and once you round you get 44ft so you are correct.
The area of a triangle is 36 sq cm. The triangle's height is 8 cm. What is the length of the base of the triangle?
Answer:
9 cm
Step-by-step explanation:
Given :
Area, A = 36cm²
Height, h = 8cm
Using the relation :
Area, A of triangle :
A = 1/2 * base * height
36 = 0.5 * base * 8
36 = 4 * base
base = 36 / 4
Base = 9 cm
Length of base is 9cm

Nathaniel goes to a store an buys an item that costs xx dollars. He has a coupon for 40% off, and then a 7% tax is added to the discounted price. Write an expression in terms of xx that represents the total amount that Nathaniel paid at the register.
Answer: He pays x*0.642
Step-by-step explanation:
Suppose that we have an object with an initial price P.
If we have a discount of X%, then the new price will be:
NP = P*(1 - X%/100%)
And if we have an increase of X%, the new price is:
NP = P*(1 + X%/100%)
In this case, we have an initial item that costs x dollars, first we have a coupon for 40% off, then we have a discount of 40%.
Then the new price is:
NP = x*(1 - 40%/100%) = x*(1 - 0.4) = x*0.6
Now we add a tax of the 7%, then the final price will be:
FP = (x*0.6)*(1 + 7%/100%) = (x*0.6)*(1 + 0.07) = x*(0.6*1.07) = x*0.642
This is the total amount he pays at the register.
