Answer:
IJ = 14Step-by-step explanation:
If the point HIJK all lies on the same line, then HI + IJ + JK = HK
2 + 2 + 3 = HK
HK = 7
Since the total length is HK
IJ = ratio of IJ/Total ratio * HK
IJ = 2/7 * 49
IJ = 2 * 7
IJ = 14
Hence the length of IJ is 14

What is 3% of 1700
Can you please explain the method please
Answer:
3% of 1700 is 51
Step-by-step explanation:
3% is the same thing as 0.03 so when you find a percentage of something, you multiply that number by the percentage. In this case, it is 3% of 1700 so you multiply 1700 by 0.03 to get your final answer of 51.
I hope this helps!
find the product of 10.2 and 6.3
Answer:
10.2*6.3=64.26
Step-by-step explanation:
Solve 102*63, then move the decimal point two numbers from the right:
Since 102*63=6426, then moving the decimal point two numbers from the right will mean 10.2*6.3=64.26
Answer:
64.26
Step-by-step explanation:
This is a simple multiplication
When you 'multiply' or 'times' even a product of a number you add it to itself a number of times, for this problem, 10.2 multiplied by 6.3 is the same as saying 10.2 + 10.2 + 10.2 = 64.26. Multiplication is therefore a quicker way of adding the same number many times, for example, 10.2 × 6.3 = 64.26. Therefore, the product of 10.2 and 6.3 is 64.26.

Answer:
y = x - 10
Step-by-step explanation:
10 less than x would be written as x - 10, and subtracting 10 from x would ensure y (the output) is always less than the number you put in for x

Is (-2, 6) a solution to this system of linear equations? (HINT: Substitute x
with-2 and y with 6 in both equations, then simplify). *
Answer:
1st Equation: -8x + y = 22
At (-2,6)
(-8*-2)+ 6 =16+6= 22: That is correct
2nd Equation: -8x - y =10
At (-2,6)
(-8*-2)-6= 16-6= 10: That is correct
Both are correct.
Hope it helps you.
Am I right?

a plumber charges $15 for a service call plus $20 per hour of service. Write an equation in slope-intercept form for the cost, y, after x hours of service. What will be the total cost for 8 hours of work?
Answer:
C= 25$ + 50$ * h
8 hours 425$
10 hours 525$
Step-by-step explanation:
Answer:
y = 20x + 15
The total cost for 8 hours of work will be $175
Step-by-step explanation:
To find the total cost for 8 hours of work, substitute the x in the equation with 8, and solve. 20 times 8 is 160. 160 + 15 is 175.

The point (-3, 2) lines on a circle whose equation is (x + 3)2 + ( + 1)2 = r2. Which of
the following must be the radius of the circle?
Answer:
3 units
Step-by-step explanation:
Equation of the circle is:
[tex] (x+3)^2 +(y+1)^2=r^2 [/tex]
[tex] \therefore [x-(-3)] ^2 +[(y-(-1)] ^2=r^2 [/tex]
Equating it with
[tex] (x-h)^2 +(y-k)^2=r^2 [/tex]
We find: h = - 3 & k = - 1
Center of the circle (C) = (-3, - 1)
Since, the point (-3, 2) lies on the circle, therefore radius of the circle wii be equal to the distance between the center of the circle (-3, - 1) and the point (-3, 2) which is on the circle.
Therefore,
[tex] r = \sqrt{[-3-(-3)]^2 +[2-(-1)]^2} [/tex]
[tex] r = \sqrt{[-3+3]^2 +[2+1]^2} [/tex]
[tex] r = \sqrt{[0]^2 +[3]^2} [/tex]
[tex] r = \sqrt{0 +9} [/tex]
[tex] r = \sqrt{9} [/tex]
[tex] r = 3\: units [/tex]

Answer:
Uhhh
Step-by-step explanation:
Answer:
9/40
Step-by-step explanation:
Tan of an angle equals the length of the side opposite the angle divided by the length of the leg adjacent to the angle. Thus, for angle C, AB is opposite it, which is 9, and although both CA and CB are adjacent, adjacent typically refers to the leg, not the hypotenuse, so we want CB, which is 40. Opposite/Adjacent = 9/40

Find the surface area
PLEASE HELP! will mark brainiest
Thank you :)
Answer:
12796 cm²
Step-by-step explanation:
[tex]SA=2(lw+lh+wh)[/tex] where l is the length, w is the width and h is the height
Plug in 42 as l, 35 as w and 64 as h
[tex]SA=2(42*35+42*64+35*64)\\SA=2(1470+2688+2240)\\SA=2(6398)\\SA=12796[/tex]
Therefore, the surface area of the figure is 12796 cm².
I hope this helps!
Answer:
Solution :-TSA = 2(lb + bh + lh)
TSA = 2(64 × 42 + 42 × 35 + 64 × 35)
TSA = 2(6398)
TSA = 12796 cu. cm

Volunteers at a food pantry pack boxes of soup into crates. How many boxes of soup will fill each crate? Show your work.
Answer:
54 boxes
Step-by-step explanation:
Dimension of crate = 12 in by 18 in by 12 in
Volume of crate = (12 * 18 * 12) = 2592 in³
Dimension of box = 4 in by 2 in by 6 in
Volume of box = (4 * 2 * 6) = 48 in³
Number of boxes of soup that will fill each crate :
Volume of crate / volume of box
2592 in³ / 48 in³
= 54 boxes

Answer:
y = -2x + 3
Step-by-step explanation:
Let's just put the three points together.
(-1, 5) (-4, 11) (-7, 17)
First, let's find the slope with y2 - y1/x2 - x1
Plug in using (-1, 5) and (-4, 11)
11 - 5/-4 + 1 = 6/-3 (simplify)
-2 is the slope
Now plug in (-7, 17) in the equation to get b or the y-intercept)
y = mx + b
17 = -2(-7) + b
17 = 14 + b (subtract 14 on both sides)
3 = b
y = -2x + 3
