wide. Find the dimensions of the
rectangle if its area is 221 sq-miles.
Answers
Answer:
1283 miklis
Step-by-step explanation:
Answer:
The lenght is 17 milesThe wide is 13 milesLet / l : the lenght of the rectangle
w : the wide of the rectangle
Step-by-step explanation:
[tex]a = l \times w \\ 221 = (w + 4) \times w \\ 221= w^{2} + 4w \\ {w}^{2} + 4w - 221 = 0 \\ (w + 17)(w - 13) = 0 \\ either \: w + 17 = 0 \\ so \: w = - 17 \: mile \: \: \: \: neglect \\ or \: w - 13 = 0 \\ so \: w = 13 \\ l = w + 4 \\ l = 13 + 4 = 17 \: mile[/tex]

→XxKim02xXa plumber charges $15 for a service call plus $20 per hour of service. Write an equation in slope-intercept form for the cost, y, after x hours of service. What will be the total cost for 8 hours of work?
Answers
Answer:
C= 25$ + 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.
find the product of 10.2 and 6.3
Answers
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.
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?
Answers
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]

320 = 30x + 20
300 = 30x
x = 10
Answer:
10 hours
Step-by-step explanation:
We already have the equation, which is y = 30x + 20. Simply substitute 320 for y, and solve for x.
320 = 30x + 20
First, subtract 20 from both sides.
320 - 20 = 30x
300 = 30x
Now divide both sides by 30.
300/30 = x
10 = x
It will take about 10 hours for Robin to travel 320 miles.

Volunteers at a food pantry pack boxes of soup into crates. How many boxes of soup will fill each crate? Show your work.
Answers
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

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

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
