V=(4/3)πr^3 (the formula for volume of sphere)
plug in 17/2 for r (17 is the diamater and r is the radius which is half of the diamater)
Put this in calc
(4/3)π17/2^3
You get 2572.44

5x-2y=2 slope intercept form?
Answer:
[tex]y = \frac{5}{2}x-1[/tex]
Step-by-step explanation:
Slope-intercept form is represented by the formula [tex]y = mx + b[/tex]. So, to place the given equation in slope-intercept form, isolate the y on the left side and arrange the terms in that matching order. Remember, whatever you do to one side, do to the other:
[tex]5x-2y = 2\\-2y = -5x + 2\\\frac{-2}{-2}y = \frac{-5}{-2} x+\frac{2}{-2} \\y = \frac{5}{2} x-1[/tex]
So, the slope-intercept form is [tex]y = \frac{5}{2}x-1[/tex].
Math questions plss mark u brainlist
Answer:
4
Step-by-step explanation:
Hello There!
To find the slope we can use the slope formula
let m = slope
[tex]m = \frac{y_2-y_1}{x_2-x_2}[/tex]
now lets find two points so we can plug the values into the formula
the points chosen is optional but the points i chose were
(5,20) and (15,60)
remember when plugging in the values into the formula we plug in the second ordered pair first so
also remember that the y values go on top and the x values go on the bottom
[tex]m = \frac{60-20}{15-5} \\60-20=40\\15-5=10\\m=\frac{40}{10} or 4[/tex]
So we can conclude that the slope of the line is 4
The boss sent you to pick up lunch with $32.10, but you forgot how many hamburgers and hotdogs to pick up! The cost of a hamburger is $1.50 and the cost of a hot dog is $1.10. You must buy a combination of 23 items.
Answer:
Step-by-step explanation:
so we can make a system of equations
y=hotdogs
x=hamburgers
you need a combination that sums to 23, so add the two and get 23:
y+x=23
and then you need to account for how much money you have and the cost.
1.50x+1.10y=32.10

Share 720cm in the ratio 3:4:2:9
Answer:
120 cm, 160 cm, 80 cm, 360 cm
Step-by-step explanation:
The ratio 3:4:2:9 is the same as the ratio 3x:4x:2x:9x
We add all the terms of the second ratio:
3x + 4x + 2x + 9x = 18x
18x = 720
x = 40
3x = 3(40) = 120
4x = 4(40) = 160
2x = 2(40) = 80
9x = 9(40) = 360
Answer: 120 cm, 160 cm, 80 cm, 360 cm

Select the 3 expressions that would give the total length of the ropes. a \large 3\frac{1}{4}+3\frac{1}{4}+3\frac{1}{4}+3\frac{1}{4} b 4 x \large \frac{12}{4} c 4 x \large \frac{13}{4} d \large \frac{12}{4}+\frac{12}{4}+\frac{12}{4}+\frac{12}{4} e \large \frac{13}{4}+\frac{13}{4}+\frac{13}{4}+\frac{13}{4}
Answer:
The correct answers are;
4 * 3 1/4
3 1/4 + 3 1/4 + 3 1/4 + 3 1/4
13/4 + 13/4 + 13/4 + 13/4
Step-by-step explanation:
Given 4 ropes each 3 1/4 feet long
1 rope = 3 1/4 feet long
4 ropes = x
cross multiply
1 * x = 4 * 3 1/4
x = 4 * 3 1/4
Since 3 1/4 is in 4 places, the total length can also be expressed as;
3 1/4 + 3 1/4 + 3 1/4 + 3 1/4
We can also rewrite as an improper fraction
Since 3 1/4 = 13/4
Total length = 13/4 + 13/4 + 13/4 + 13/4

Melvin borrowed $1,200 for furniture. His monthly payments were $60 for 24 months.
How much interest did Melvin pay on the loan?
$240
$1,200
$1,440
$2,880
Answer:
240.
Step-by-step explanation:
First you need to find out what his monthly payments are (60x24=1440)
Then you would subtract his monthly payments (1440) to the amount that he borrowed for the furniature (1200) which would give you 240.

Find the circumference and area of the circle to the nearest hundredth. Use 3.14 for π. Round to the nearest hundredth if necessary.
56 is the cm.
Answer:

Circumference=2×3.142×r
c= 2×3.142×28=175.952
hundredth =175.95cm
Area=3.142×r^2
A= 3.142×28^2=2463.328

Simplify. Show your work.
a. |5 - 7| =2
b. -3|11 - 15|=-12
Answer:
|5 - 7| =2
What you want to do first is to do the equation 5-7 which is -2 but there is an absolute value sign so 2.
-3|11 - 15|=-12
For this one it is a little more difficult but all you have to do is do the equation 11-15 which is -4 but there is an absoulte value sign so 4 you then multiply 4 by -3 which is -12 bam.

The edge of a cube is 4 inches.
The area of a cross section perpendicular to one face is
square inches, and its perimeter is
inches
Answer:
Sketch of a cube with side = 4 in as shown.
The shaded area is perpendicular to the right and left vertical faces of the cube, so the cross section is a square with each side equal to 4 in.
The area of the cross section is
4*4 = 16 in²
The perimeter of the cross section is
4+4+4+4 = 16 in.

what is the answer to 6a + 6c =126
Answer:
Step-by-step explanation:
You can solve 6a + 6c =126 for either a or c, but until you have a second equation in either a or c or both, you cannot find the values of a and c.
6a + 6c =126 reduces to 6(a + c = 23), or just a + c = 23. Then either a = 23 - c or c = 23 - a, but we cannot find a or c as a specific numeric value.

Step-by-step explanation:

B) True
C) True
D) False Solution is actually (-3, -3)
work below
Note: Used Elimination Method
Multiply the first equation by -2,and multiply the second equation by 1.
−2(−2x+y=3)
1(3x+2y=−15)
Becomes:
4x−2y=−6
3x+2y=−15
Add these equations to eliminate y:
7x=−21
Then we solve 7x = −21 for x:
7x = −21
7 7
(we Divide both sides by 7)
x=−3
Now that we've found x let's put it back in to solve for y.
Put down an original equation:
−2x+y=3
Substitute−3 for x in−2x+y=3:
(−2)(−3)+y=3
y+6=3(Simplify both sides of the equation)
y+6+−6=3+−6(Add -6 to both sides)
y= −3
Solution
(-3, -3)

- A square flower bed has an area of 169/36 square yards. What is the perimeter of the flower bed?
Answer:
Step-by-step explanation:
Length of each side = √(169/36)
= √169/√36
= 13/6 yards
Perimeter = 4(13/6) = 26/3 yards
Perimeter of the flower bed is 26 / 3 yards
Given:
[tex]Area\ of\ square\ flower\ bed\ = \frac{169}{13} square\ yard\\\\[/tex]
Find:
Perimeter of the flower bed
Computation:
Area of square = side²
So,
[tex]Area\ of\ square\ flower\ bed\ = \frac{169}{13} square\ yard\\\\Side^2 = \frac{169}{36} \\\\Side^2 = [\frac{13}{6}]^2 \\\\Side = \frac{13}{6} \ yard[/tex]
Perimeter of square = 4(Side)
[tex]Perimeter\ of\ the\ flower\ bed = 4(\frac{13}{6} ) \\\\Perimeter\ of\ the\ flower\ bed = \frac{26}{3} \ yards[/tex]
