Answer:
Answer is 7/2 cm
Step-by-step explanation:
1. Set a ratio
[tex]7=\frac{3V}{l*w}:h=\frac{3V}{l*2w}[/tex]
2. Move 2w from denominator to LHS (Left hand side)[tex]\frac{7}{2}w=\frac{3V}{l}[/tex]
[tex]\frac{7}{2w}=\frac{3V}{l}[/tex]
3. The four options are 7/4, 7/2, 14 or 28 cm
Answer:
Choice B
7/2 cm

it's asking to write an equation in slope-intercept form for the line with slope -4 and y-intercept 7. then graph the line. please help
Answer:
Equation = y = -4x+7
See the graph below
Step-by-step explanation:
The equation of the line in slope intercept form is expressed as;
y = mx+c
Given
slope m = -4
y-intercept c = 7
Substitute
y = -4x + 7
Get the x intercept.
at y = 0
0 = -4x + 7
4x = 7
x = 7/4
x = 1.75
The x coordinate (1.75, 0)
Get the y intercept
at x = 0;
y = -4(0)+7
y = 0+7
y = 7
The y coordinate is (0, 7)

Answer:
h=14
Step-by-step explanation:
So since the triangular shape is a right triangle, we can use a Pythagorean triple. For this question, lets use (5,12,13). But, if you just want to use the formula:
5^2+x^2=13^2
25=x^2=169
x^2=144
x=12
That means a part of h is 12. BUT, we also have an extra two ft on top of the triangle, so h=12+2=14.
whats the area help me youll get brainliest answer
Answer:
Area = 14m²Step-by-step explanation:
area of rectangle = length × breadth
area of rectangle = 4 × 2
area of rectangle = 8m²
area of Triangle = 1/2 × base × height
area of Triangle = 1/2 × 4 × 3
area of Triangle = 6m²
Total area = 8 + 6
Total area = 14m²

Answer: 72
Step-by-step explanation:
Answer:
72
Step-by-step explanation:
Circumference of a circle = 2πr
Area of a circle: πr^2
Plug in:
C = 2πr
30.1 = 2(3.14)r
30.1 = 6.28r
r = 4.79 (Dividing both sides by 6.28)
Use area of the circle:
A = 3.14(4.79)^2
= 72.044474
Round to nearest whole number = 72

What two numbers multiply to 30 and add to -17
Answer:
-15 and -2
Step-by-step explanation:
Since a negative times a negative equals a positive, but when added, still stays a negative, the factors must both be negative.
Negative Factors of 30:
-30 + -1 = -31
-15 + -2 = -17
-10 + -3 = -13
-6 + -5 = -11
The two factors of 30 that add up to -17 are -15 and -2.
Hope this helps. Have a nice day.

Answer:
The answer is going to be No, (-1, 2) is only a solution for the equation 2x + 5y = 8
Let's find out if it is a solution first:
3 x -1 - 2 x 2 = -3 - 4 = -7
2 x -1 + 5 x 2 = -2 + 10 = 8
From this, you can tell that (-1, 2) is only a solution to 2x + 5y = 8

Answer:
≈ £ 4584.38
Step-by-step explanation:
Firstly, we need to find the number of litres that Mr. Leonard needs to fill up his tank:
We know that there is already 450 litres in the 1200 litre tank, so he must need 1200 - 450 = 750 litres.
I'm not quite sure what the variable p means, but I'm going to assume that p represents the number of litres and that 81.5 is the price per litre in pounds.
So:
Total price = 81.5p
Total price = 81.5(750)
Total price = £61125
We have to remember though that the question is asking for the discount and not the discounted price, so:
61125 × 7.5%
61125 × 0.075 = 4584.375
≈ £ 4584.38
The mean of 10 numbers is 14 three of the numbers have a mean of 4. The remaining 7 numbers are 15, 18, 21, 5, M, 34 and 14 find:
(I) The sum of the remaining 7 numbers,
(ii) the value of m.
please answer ASAP.. please
Answer:
21
Step-by-step explanation:
sum of all numbers is 10×14=140
add the 6no=107
sum of3 no is 3×4=12
107+12=119
140-119=21

How can you solve this equation? 15 = y - 5
A. Subtract 5 from each side.
B. Subtract 15 from each side.
C. Add 5 to each side.
D. Add 15 to each side.
Answer:
C) add 5 to each sides.
Step-by-step explanation:
1) Add 5 to both sides.
[tex]15 + 5 = y[/tex]
2) Simplify 15 + 5 to 20.
[tex]20 = y[/tex]
3) Switch sides.
[tex]y = 20[/tex]
You need to add 5 to each sides in order to solve this equation. if you do, you'll get an answer of 20.
The width of a rectangle measures (9h 1) centimeters, and its length measures
(2h – 4) centimeters. Which expression represents the perimeter, in centimeters, of
the rectangle?
0-2 + 8h
0-10 + 22h
Submit Answer
16h - 4
0-5 + 11h
Answer:
(22h - 8) centimeters
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
= 2{(9h - 1) + (2h - 4)}
= 2(9h - 1 + 2h - 4)
= 2(11h - 4)
= (22h - 8) centimeters

In triangle EFG, the measure of angle E is 97 degrees, and the measure of angle F is 15 degrees. What is the measure of angle G?
Answer:
Measure of angle G is 68°.
Step-by-step explanation:
In triangle EFG,
Measure of angle E = 97°
Measure of angle F = 15°
By the triangle sum theorem,
Sum of measures of all interior angles of triangle = 180°
m(∠E) + m(∠F) + m(∠G) = 180°
97° + 15° + m(∠G) = 180°
m(∠G) = 180° - 112°
= 68°
Therefore, measure of angle G is 68°.

The tip of a 8 cm minute hand of a clock sweeps out circular arcs.
What is the length of the arc made by the tip of the minute hand between 3:12 and 3:32?
Use 3.14 for pi. Round your answer to the nearest hundredth.
Enter your answer in the box.
Answer:
16.75 cm
Step-by-step explanation:
The circumference of the circle is πd
The diameter is 16, so the circumference is 16π.
The minute hand goes for 20 min between 3:12 and 3:32
20 min is 1/3 of 60 min.
Therefore, the minute hand swept 1/3 of the circumference, or 1/3(16)π
1/3(16)π = 1/3(16)(3.14) = 16.75 cm

A toy box is 5 feet long, 24 inches wide and 30 inches high. What is the volume of the toy box in cubic feet?
Answer:
25 cubic feet
Step-by-step explanation:
You need to convert all units to feet and then multiply the dimensions.
24 inches is 2 feet
30 inches is 2.5 feet
So, you would multiply 5X2X2.5= 25.

h(j + i) - k5 + h
when h = 3, i = 4, j = 2, and k = 1
pls put how you did it
Answer:
16
Step-by-step explanation:
First you want to plug in all the numbers where the letters are
h ( j + i )- k(5) + h
3 ( 2 + 4 )- 1(5) + 3
After this step you will have to distribute the 3 outside the parenthesis. Which you do by multiplying everything in side the parenthesis by the outside number which is three.
6 + 12 - 1(5) + 3
Then you just follow PEMDAS to solve for the rest
6 + 12 - 5 + 3
18 - 5 + 3
13 + 3
