Weston has $4,000 in his bank account and withdraws $30 a week. Evie has $2,800 in her
bank account and deposits $40 a week.
The week in which Evie would have more money than Weston is the 18th week.
Let this equation represent the amount of money Weston would have in x weeks be: $4000 - $30x
Let this equation represent the amount of money Evie would have in x weeks be: $2800 +$40x
The first step is to determine when they would have the same amount of money:
$4000 - $30x = $2800 +$40x
$4000 - $2800 = $40x + $30x
1200 = $70x
x = 1200 / 70 = 17.14 weeks
After 17 weeks, Evie would have more money than Weston.
Here is the complete question: Weston has $4,000 in his bank account and withdraws $30 a week. Evie has $2,800 in her bank account and deposits $40 a week. When will Evie have more money than Weston (in
weeks)?

C. 40-52 and 14-26
D. 53-65 and 14-26
Answer:
C
Step-by-step explanation:
60+80=140 which is definitely higher than 100-120
Answer:
C. 40-52 and 14-26
Step-by-step explanation:
The age groups that can be more than 120 in number as the 27-39 age group can only be 2 groups.
The 40-52 is an age group which has 80 in number and below it the 14-28 age group has 60 in age group.
60+80 is more than the 27-39 ager group by 20 in number. Therefore, the C. 40-52 and 14-26 age groups are the 2 groups that have more than the 27-39 age group.

The blue print of Vanessa's new home was drawn with a scale factor of 1 foot = 0.33 inch. The
actual length of the living room was to measure 12 feet. Determine the length of the living
room shown in the blueprint.
The length of the living room in the blue print is 3.96 inch
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the given question
We have,
1foot = 0.33 inch
The actual length of the living room =12feet.
Therefore,
The length of the living room in the blue print = 12 × 0.33 = 3.96inch
Hence, the length of the living room in the blue print is 3.96 inch.

the area of a window is 192 in squared. The width if the window is four inches more than half the length of the window. What are the dimensions of the window?
Answer:
Length = 16 inches and width = 12inches
Step-by-step explanation:
A = 192 in² . The width is 4 + 1/2x. therefore let x = length
Area = LW
192 = x(4 + 1/2 x)
192 = 4x + 1/2x²
384 = 8x + x² Multiply each term by 2 to make a
384 + 16 = x² + 8x + 16 Complete the square
400 = (x + 4)²
[tex]\sqrt{400} = \sqrt{(x + 4)^2}[/tex]
± 20 = x + 4
20 = x + 4 or -20 = x + 4
20 - 4 = x or -20 - 4 = x
16 = x or -24 = x reject the negative amount
Length = 16
width = 4 + 1/2(16); 4 + 8 = 12
If RV = x+6, US = 5x-9, and RS = 11, find VT and ST
The values of VT and ST for the given rectangle are 13 and 23.56 respectively.
The given parameters:
RV = x + 6US = 5x - 9RS = 11The value of VT and ST is calculated as follows;
from the given diagram we can conclude the following;
2RV = RT = US
[tex]2(x + 6) = 5x - 9\\\\2x + 12 = 5x - 9\\\\12 + 9 = 5x - 2x\\\\21=3x\\\\x = 7[/tex]
RT = 2RV = 2VT = 2(7 + 6) = 26
VT = ¹/₂ x 26
VT = 13
The value of ST can be determined from Pythagoras theorem as follows;

Answer:
V = 113.1
Step-by-step explanation:
V= 4/3 π r^3
V= 4/3 x 3.14 x 3^3
V= 4.19 x 27
V= 113.13
rounded to 113.1
In this question all the required information is given so we'll simply have to solve.
[tex]\large\boxed{\bold{V= \ \frac{4}{3}\pi{r}^{3}}}[/tex]
Let's substitute the values according to the formula.
[tex]\bold{ V= \frac{4}{3}×\pi×{3}^{3}}[/tex]
[tex]\bold{=113.0973355 \ {m}^{3}}[/tex]
Now, we can round off to the nearest tenth.
If the value in hundredths place is greater than 5 you'll have to round up. If not you'll have to keep it as it is.
In this, the value in hundredths place is greater than 5 so we'll have to round up by adding 1 to the tenths place.

Idrissa collected pennies in a fundraiser. He measured the mass of all the pennies he collected to be2,400 grams. Two pennies put together have a mass of 5 grams. How much money did Idrissa raise in
this fundraiser?
The total amount of pennies Idrissa raised in this fundraiser is = 960 pennies
The total mass of all the pennies = 2,400g
But two (2) pennies = 5g
Therefore, to calculate the total amount of pennies Idrissa raised you cross multiply.
That is: 2 pennies = 5g
x pennies = 2,400g
Making x the subject of formula,
[tex] x = \frac{2 \times 2400}{5} [/tex]
[tex]x = \frac{4800}{5} [/tex]
[tex]x = 960[/tex]
Therefore the total amount of pennies Idrissa raised in this fundraiser is = 960 pennies.
