Answer:
Paint set cost = 10.5 , Sketch book cost = 7 , Brush cost = 1.75
Step-by-step explanation:
Let the cost of paint set be = p
Cost of sketchbook 's' = (2 / 3) p
Cost of brush 'b' = 1/4th of s = 1 / 4 [ (2 / 3) p ] = (1 / 6) p
Total expenditure = Money bought - Money left = 23.25 - 4 = 19.25
Total expenditure = Cost of (pen + of sketchbook + of brush) = p + s + b
= p + (2 / 3) p + (1 / 6) p = 19.25 → p + 2p / 3 + p / 6 = 19.25
( 6p + 4p + p ) / 6 = 19.25 → 11p / 6 = 19.25 → p = ( 19.25 x 6 ) / 11
p = 10.5 ; s = (2 / 3) p = 2 / 3 (10.5) = 7 ; b = (1 / 6) p = 10.5 / 6 = 1.75
A coach buys a jersey and a team cup for each of the 10 players on the basketball team. Each team cup costs $16. The coach spends a total of $296 for the jerseys and team cups. Enter an equation that models the situation with u, the cost of one jersey.
please someone explain
Answer:
Cost of each jersey = $13.6
Step-by-step explanation:
Given:
Cost of each team cup = $16
Total amount spend = $296
Total number of team cup = 10
Total number of jersey = 10
Find:
Cost of each jersey
Computation:
Assume;
Cost of each jersey = c
So,
16(10) + (c)(10) = 296
160 + 10c = 296
10c = 296 - 160
10c = 136
c = 136 / 10
Cost of each jersey = $13.6

Which can be represented by the expression 17 – 2x? A. 17 less than twice a number B. the difference between 17 and twice a number C. a number x squared, subtracted from 17 D. 17 less than a number x squared
Answer:
B.
Step-by-step explanation:
If x is a number, then twice a number is 2x. The difference between 17 and 2x is 17-2x.
Common Error:
A. says 17 less than twice a number. Since it is 17 less, it is 2x-17 not 17-2x.

Ok I am not so sure about this one, since this was a LOT of counting, and unless you want to see 5 pages of calculations, I'm just going to go on a limb and say trust me. However, if you really want to see for yourself, I'll give you a hint. For the first 1***1 numbers, the sum is 1440. For the 2***2 numbers, the sum is 1683. Try to calculate this to 9***9 to find the answer! Again, not sure about my answer if it's wrong, sorry!

What would be your net earnings if you put $2500 in a savings account with an annual interest rate of 5% with a monthly fee of $5?
Answer:
Net Earnings = $65
Step-by-step explanation:
Money deposited in saving account = $2500
Interest rate = 5% pa = 5% of 2500 = $125
Fee = $5 (monthly). So annual fee = 12 x 5 = $60
So, net earning = Interest Earning - Annual Fee
= $125 - $60 = $65

find two numbers if their sum is 3/5 and their difference is 7 1/5
Answer:
A = 3 + 9/10
B = -(3 + 3/10)
Step-by-step explanation:
We have two numbers, A and B, such that:
A + B = 3/5
A - B = 7 + 1/5
To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:
A = 3/5 - B
Now we can replace this in the other equation:
A - B = 7 + 1/5
(3/5 - B) - B = 7 + 1/5
3/5 - 2*B = 7 + 1/5
-2*B = 7 + 1/5 - 3/5
-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5
B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)
Now that we know the value of B, we can use the equation
A = 3/5 - B
To find the value of A:
A = 3/5 - ( -(3 + 3/10))
A = 3/5 + (3 + 3/10) = 6/10 + 3 + 3/10 = 3 + 9/10
The numbers are:
A = 3 + 9/10
B = -(3 + 3/10)
The recipe for a large batch of cookies uses 1 kilogram of flour. Another recipe uses 700 grams of flour. How much flour is needed to make two batches of each recipe?
1 kilogram = 1,000 grams
Answer:
3,400 grams
Step-by-step explanation:
The total amount of flour needed to make two batches of each recipe is 3400 grams.
How much gram is equal to 1 kilogram?1000 grams is equal to 1 kilogram.
Amount of flour used in one batch of the first recipe= 1 kilogram
So, the amount of flour used in two batches of the first recipe=2 kilogram =2000 grams.
Amount of flour used in one batch of the second recipe= 700 grams
So, the amount of flour used in two batches of the second recipe= 2*700=1400 grams.
Total amount of flour needed = 2000+1400 =3400 grams.
Hence, The total amount of flour needed to make two batches of each recipe is 3400 grams.

A rectangular pyramid has a height of 15 cm. What is the volume of the rectangular pyramid in cubic feet?
Answer:
The answer is 360
Step-by-step explanation:
the formula for the volume of a rectangular based pyramid is 1/3 times the base area times the height and the height is given as 15 cm the base parameters are 9 and 8 respectively so deep area of the rectangular base is 9 * 8 * 15 that is 1080 x 1/3 which is 360
A high school soccer team is going to Columbus to see a professional soccer game. A coordinate grid is superimposed on a highway map of Ohio. The high school is at point (3, 4) and the stadium in Columbus is at point (7, 1). The map shows a highway rest stop halfway between the cities. What are the coordinates of the rest stop? What is the approximate distance between the high school and the stadium? (One unit = 6.4 miles.)
Answer:
a) The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].
b) The approximate distance between the high school and the stadium is 32 miles.
Step-by-step explanation:
a) The rest stop is located in the midpoint of the line segment between the high school and the stadium. Vectorially speaking, we use the following formula:
[tex]C(x,y) = \frac{1}{2}\cdot A(x,y) + \frac{1}{2}\cdot B(x,y)[/tex] (1)
Where:
[tex]A(x,y)[/tex] - Coordinates of the high school.
[tex]B(x,y)[/tex] - Coordinates of the stadium.
[tex]C(x,y)[/tex] - Coordinates of the rest stop.
If we know that [tex]A(x,y) = (3, 4)[/tex] and [tex]B(x,y) = (7,1)[/tex], then the coordinates of the rest stop are, respectively:
[tex]C(x,y) = \frac{1}{2}\cdot (3, 4) + \frac{1}{2}\cdot (7, 1)[/tex]
[tex]C(x,y) = \left(\frac{3}{2}, 2 \right) + \left(\frac{7}{2}, \frac{1}{2} \right)[/tex]
[tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex]
The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].
b) The approximate distance between the high school and the stadium ([tex]d[/tex]), in miles, is the product of the Length Equation of the Line Segment and the scale factor:
[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex] (2)
Where:
[tex]r[/tex] - Scale factor, in miles.
[tex]\Delta x[/tex], [tex]\Delta y[/tex] - Horizontal and vertical distances between the high school and the stadium, no unit.
If we know that [tex]r = 6.4\,mi[/tex], [tex]\Delta x = 4[/tex] and [tex]\Delta y = -3[/tex], then the distance between the high school and the stadium is:
[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex]
[tex]d = (6.4\,mi)\cdot \sqrt{4^{2}+(-3)^{2}}[/tex]
[tex]d = 32\,mi[/tex]
The approximate distance between the high school and the stadium is 32 miles.

In triangle ABC, if angle A measures 78° and angle B measures 63º, what is the measure of angle C?
Answer:
∠C=39°
Step-by-step explanation:
The interior angles of a triangle will always have a sum of 180°.
∠A+∠B+∠C=180°
78°+63°+∠C=180°
∠C=180°-78°-63°
∠C=39°
Answer:
39 degrees
Step-by-step explanation:
All triangles will add up to 180 degrees. So, you know that angle C added with angles A and B will equal 180. if you take 180, minus 78, minus 63, you get the answer 39.

Answer:
23.25 m^3
Step-by-step explanation:
First you must find the area of the base you find it like this:
A(area)=1/2(one half)3.1(base)2.5(height)
you get 3.875(this is the area of the base)
now you have to multiply the area of base times the area of height like this:
A(area)=3.875(area of base)6(height)=23.25
so the answer is 23.25m^3
