Answer:
$5 for a dog treat
$3 for a cat treat
Step-by-step explanation:
week 1: 6d + 4c = 42
week 2: 2d + 7c = 31
*used calculator & guessed what each treat costs*
WEEK 1:
6(5) + 4(3) = 42
30 + 12 = 42
42 = 42
WEEK 2:
2(5) + 7(3) = 31
10 + 21 = 31
31 = 31

4 out of 5 phones that are recycled, have cracks on the screens. If 30 phones got recycled today, how many probably had cracks on their screens?
Answer:
24
Step-by-step explanation:
The unit rate of 4:5 is 0.8 because 4 divided by 5 is 0.8
0..8 x 30= 24
solve: 6d = 84
*with the steps*
Answer:
d = 14
Step-by-step explanation:
6d = 84
Divide each side by 6 to isolate d
6d/6 = 84/6
d =14

Two triangular prisms with the same altitude always have the same surface
area.
A. True
B. False
The prisms might have different base areas, which would contribute to overall having different surface areas even if the altitude (aka height) of each prism was the same.

Find the volume of the frustrum of the right circular cone generated by rotating the line y = 3x+1 about the x-axis between x = 0 and x = 2.
Answer:
38π cubic units
Step-by-step explanation:
The volume V = ∫₀²πy²dx
Since y = 3x + 1, dy = 3dx ⇒ dx = dy/3
So, when x = 0, y = 3(0) + 1 = 0 + 1 = 1
when x = 2, y = 3(2) + 1 = 6 + 1 = 7
So, changing the variable to y and the limits of integration from y = 1 to y = 7, we have
V = ∫₀²πy²dx
V = π∫₁⁷y²dy/3
V = π[y³/3]₁⁷/3
V = π[y³]₁⁷/9
V = [7³ - 1³]π/9
V = [343 - 1]π/9
V = 342π/9
V = 38π cubic units

=======================================================
Explanation:
Let x be the angle measure of that dark area. That angle x must add to the other angles 25, 90, and 25 to get a full 360 degree rotation.
So,
x+25+90+25 = 360
x+140 = 360
x = 360-140
x = 220
The dark area angle is 220 degrees
This is known as a reflex angle due to it being larger than 180 degrees, but it's less than 360 degrees. In symbolic terms, any reflex angle is one such that 180 < x < 360.
Use the diagram to answer questions 24 and 25.

14. Jerry charges a fee of $45 plus $15 per hour to rent a motorbike. Write an equation to
calculate rental cost and tell what x and y mean. If you have $120 to spend, how long can you rent
for?
Answer:
5 hours, y= how much money it will cost, and x represents how many hours
Step-by-step explanation:
y= 15x+45
120= 15x+45
-45 -45
75= 15x
75/15×= 5 hours
How do I find the measure qrs help????
I’m very confused thanks guys
Answer:
I do not know good luck my bro
Step-by-step explanation:
Answer:
∠QRS = 72°
Step-by-step explanation:
∠R + ∠Q = 180° (supplementary angles)
18x + 12x = 180
30x = 180
x = 6
∠R = 12x = 72° ∠Q = 18x = 108°

Answer: Line 4
Step-by-step explanation: The slope of this line is angled downward. The others are either angled upward or straight up. The vertical and horizontal lines have 0 in their slopes. So, line 4 is the only line with a negative slope because it has a negative number in the slope. ((x,y), y would be negative.)
Answer:
Hi, there your answer will D.4

The arithmetic mean of the monthly salaries of two people is $4444. One person earns $3191 per month. What is the monthly salary of the other person?
Step-by-step explanation:
Write what you know
mean is: Sum of all data points / Number of data points
any unknown number we'll call x
so youd write
(x + $3191) / 2 = $4444
Solve for x
let me know if you need further help
its me arg i need help
Answer:
x=8
Step-by-step explanation:
so since the whole thing should equal 180, and the right triangle is 90,
(3x+11)+(5x+15)=90 then solve for that
8x+26=90
8x=64
divide both sides by 8
so x=8
then plug in 8 for the xs so c is 3(8)+11 --> 24+11 so m<C=35*
m<D=90*
5(8)+15 40+15 so m<E=55

Step-by-step explanation:
System of Equations Problem.
Solve v(7)+b(6)=394;v(3)+b(12)=612
Solve 6b+7v=394 for b
Add -7v to both sides.
6b+7v+−7v=394+−7v
6b=−7v+394
Divide both sides by 6.
[tex]b=\frac{-7}{6} v+\frac{197}{3}[/tex]
Substitute [tex]b=\frac{-7}{6} v+\frac{197}{3}[/tex] for b in 12b+3v=612
12b+3v=612
[tex]12(\frac{-7}{6} v+\frac{197}{3} )+3v=612[/tex]
Simplify both sides of the equation.
−11v+788=612
Add -788 to both sides.
−11v+788+−788=612+−788
−11v=−176
[tex]\frac{-11v}{-11} =\frac{-176}{-11}[/tex]
v=16
Substitute 16 for v in [tex]b=\frac{-7}{6} v+\frac{197}{3}[/tex]
[tex]b=\frac{-7}{6} v+\frac{197}{3}[/tex]
[tex]b=\frac{-7}{6}(16)+\frac{197}{3}[/tex]
Simplify both sides of the equation.
b=47
Answer:
b=47 and v=16
explain why n(n-1) must be an even number
n & n - 1 are two consecutive numbers which means one of is surely even and the other one is odd.
_______________________________
Suppose that n is an even number;
So we can right n like this :
n = 2t
Thus :
n - 1 = 2t - 1
_______________________________
n( n - 1 ) = 2t( 2t - 1 ) = 2 ( 2t^2 - t )
= 2 ( q ) = 2q
The number obtained is a multiple of 2, so it is definitely even because all numbers are even multiples of 2.

Solve for x.
5x+2y=13
x+2y=9
Answer:
x = 1
y =
5x + 2y = 13
x + 2y = 9
Add both equations.
6x + 4y = 22
Solve for x.
6x = 22 - 4y
x = 22/6 - 4/6y
step-by-step explanation:
Put x as 22/6 - 4/6y in the second equation and solve for y.
22/6 - 4/6y + 2y = 9
-4/6y + 2y = 9 - 22/6
4/3y = 16/3
y = 16/3 × 3/4
y = 48/12
y = 4
Put y as 4 in the first equation and solve for x.
5x + 2(4) = 13
5x + 8 = 13
5x = 13 - 8
5x = 5
x = 5/5
x = 1
find the value of x, if the slope of the line joining (4,3) and (x,5) is 2/3?
Answer:
Step-by-step explanation:
here,x1=4,y1=3,x2=x and y2=5
slope=2/3
use formula
slope=y2-y1/x2-x1
2/3=5-3/x-4
2/3=2/x-4(do cross multiplication)
2(x-4)=3*2
2x-8=6
2x=6+8
x=14/2
x=7
