A meal that cost $50 had a 20% tip and 5% sales tax. How could you calculate your final total bill?
Answer:
$57.50
Step-by-step explanation:
find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5

Answer:
A and B are correct
Step-by-step explanation:
if x:y is 1:3 then x is 1 and y is 3
1/3 of 3 is 1 so A is correct
3/4(1+3) is 3 so B is correct
But
1/4 × 3 is not 1 so C is not correct

A tv costs $215 and has a 30% increase. What is the amount of increase? Show your work
i well try to give brainlist for first to answer correctly
Answer:
The price increased by 64.5, which makes a total of 279.5
Step-by-step explanation:
215*0.30 = 64.5
215 + 64.5 = 279.5
0.30 = 30% of 100
When you multiply by 0.30 you get 30%, or with any decimals, like multiply by 0.50 to get 50% of something, etc.
−5x + y = −3
3x − 8y = 24
Answer:
x = 0
y = -3
Step-by-step explanation:
-5x + y = -3 --------------(I)
3x - 8y = 24 ------------(II)
Multiply the equation (I) by 8
(I)*8 - 40x + 8y = -24
(II) 3x - 8y = 24 {Add and y will be eliminated}
-37x = 0
x = 0
Plugin x = 0 in equation(I)
-5*0 + y = -3
0 + y = -3
y = -3
Answer:
- 5x + y =-3 ......1
3x -8y = 24.........2
eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3
-40 x +8 y =-24 ...........3
3 x - 8y = 24 ......... 2
·································
-37 x +0 = 0
··························
x =0
put x = 0 in equation 2
3 x -8 y =24
3×0 -8 y = 24
0 -8 y=24
-y =24÷8
-y =3
y = -3
ans ;
x = 0
y = -3

2. A water tank is in the shape of a right circular cylinder with a height of 9
feet and a volume of 225 pi cubic feet. What is the diameter of the water
tank? *
Answer:
10 ft.
Step-by-step explanation:
V = Bh where B = area of the base, which is a circle in your problem.
So, B = [tex]\pi r^{2}[/tex]
225π = π[tex]r^{2}[/tex](9)
[tex]r^{2}[/tex] = 25
r = 5 ft
diameter = 2r = 10 ft.
divide 24xy² by 6yz²
Answer:
4xy/z^2
Step-by-step explanation:
Here, we want to make a division
We have this as;
24xy^2/6yz^2
that will be
24/6 * x * y^2/y * 1/z^2
= 4 * x * y * 1/z^2 = 4xy/z^2

Step-by-step explanation:
10 times 9 equals 90
Anyone know the answer to this?
Answer:
hello again
Step-by-step explanation:
the radius of the circle is 6mm
for having the circumference we need diameter
for having diameter we should multiply in 2
so:
[tex]d = 2r \\ \\ d = 2 \times 6 = 12mm \\ v = \pi \: d \\ v = 12\pi \: mm[/tex]

In quadrilateral RSTU in the coordinate plane, RS | TU and RS = 6. Which additional statement allows you to conclude that RSTU is a
parallelogram?
Answer:
A. ST = RU
Step-by-step explanation:
Quadrilaterals are four sided figures. Examples are: square, rectangle, trapezium, parallelogram etc. A parallelogram is a quadrilateral that has equal opposite and parallel sides.
This implies that in the given question since RS || TU, then;
RS = TU = 6
So that for RSTU to be a parallelogram,
ST = RU
Thus, the appropriate option to the question is A.

A few friends went bowling. The scores
are given below. Use the scores to
calculate the range of the data. *
(1 Point)
104, 117, 104, 136, 189, 109, 113, 104
Answer:
The range here is 85
Step-by-step explanation:
Here, we want to calculate the range of the data
Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset
From the given data points, the highest value is 189, while the lowest value is 104
So the range is the difference between the two which is;
189-104 = 85

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of length to width 5 to 3, what is the value of x
Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:
[tex]\frac{L}{W}=\frac{5}{3}[/tex]
Where:
L represents the new length W represents the new widthNow, we know that each dimension is reduced by x inches, it means:
[tex]L=18-x[/tex]
[tex]W=12-x[/tex]
Then, we will have:
[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]
Finally, we just need to solve it for x.
[tex]3(18-x)=5(12-x)[/tex]
[tex]5x-3x=60-54[/tex]
[tex]2x=6[/tex]
[tex]x=3[/tex]
Therefore, the value of x = 3.
I hope it helps you!
