Answer:
There are 32 cookies left
Step-by-step explanation:
There are c cookies when we started
c* 20% = 8 cookies
Change to decimal form
c * .20 = 8
Divide each side by .2
c * .2 / .2 = 8/.2
c =40
There are 40 cookies when we started
40 -8 = 32
There are 32 cookies left

Yuson must complete 30 hours of community service. She does 2 hours each day. Which linear equation represents the hours Yuson left after x days?
Will mark brainliest if correct
Answer:
y = 30 - 2x
Step-by-step explanation:
She must complete 30 hours, so we start at 30 hours.
Each day, she has 2 less to do after she does her service hours.
So if x = # of days, then that is -2x
Put that together,
y = 30 - 2x

There are 165 laptops and desktop computers in a lab. There are 9 more laptops than desktop computers. What is the total number of laptops in the lab?
Answer:
87
Step-by-step explanation:
Let d = number of desktops.
Let a = number of laptops.
a + d = 165
a = d + 9
d = a - 9
a + d = 165
a + a - 9 = 165
2a - 9 = 165
2a = 174
a = 87

Answer:
y int is (0,5)
slope is m=-2
y=-2x+5
Step-by-step explanation:
The line has a slope of -2 and a y-intercept of y=4. (y=-2x+4)
Explanation: You can tell by where the line is landing on the x and y intercepts and it's as easy as counting lines. As far as the y-intercept goes, you can tell that by looking where the line crosses the y axis. And in this case it's (0,4) making your y-intercept, y=4.

Answer:
x = 165°
Step-by-step explanation:
x° = 360 - (the measure of one interior angle of the octagon + the measure of one interior angle of the equilateral ∆)
Each interior angle of a regular octagon = 135° ([tex] \frac{(n - 2)180}{n} = 135°)
An equilateral ∆ has equal angles, each measuring 60°.
Therefore:
x° = 360° - (135° + 60°)
x = 360 - 195
x = 165°
Answer:
165°

Answer:
15.25 or 15 if you need it to be rounded.
Step-by-step explanation:
-11 on both sides to get 5x=1x+61. Then, -1x on both sides to get 4x=61. Then to find x you do 61 divided by 4 which is 15.25.

Need help ASAP
Answer:
x = 20°
Step-by-step explanation:
So basically, since the 2 values are on the opposite side of an "x," you just set the 2 values each to each other and solve for x.
6x - 20 = 100
+20 +20
6x = 120
÷6 ÷6
x = 20
8x − 4y = −16
3x + 15y = −6

Rodrigo planted flowers in a section of a circular garden as shown. Calculate the closest area of this sector of the garden to the nearest whole number.
Answer:
[tex]A = 118ft^2[/tex]
Step-by-step explanation:
See attachment for complete question.
From the attachment, we have:
[tex]\theta = 80[/tex]
[tex]r = 13ft[/tex] -- Radius
Required
Determine the area of the sector
Area (A) of a sector is calculated as:
[tex]A = \frac{\theta}{360} * \pi r^2[/tex]
Substitute values for r and [tex]\theta[/tex]
[tex]A = \frac{80}{360} * \pi 13^2[/tex]
[tex]A = \frac{80}{360} * \pi *169[/tex]
[tex]A = \frac{80*169}{360} * \pi[/tex]
[tex]A = \frac{13520}{360} * \pi[/tex]
Take [tex]\pi[/tex] as [tex]\frac{22}{7}[/tex]
[tex]A = \frac{13520}{360} * \frac{22}{7}[/tex]
[tex]A = \frac{13520 * 22}{360 * 7}[/tex]
[tex]A = \frac{297440}{2520}[/tex]
[tex]A = 118ft^2[/tex]-- approximated

What is the surface area of the right triangular prism
A 2,127 square centimeters
B 2,367 square centimeters
C 4,440 square centimeters
D 5,920 square centimeters
Answer:
A
Step-by-step explanation:
Area of a base: 16 × 15 ÷ 2 = 120
Area of sides:
37 × 15 = 555
37 × 16 = 592
37 × 20 = 740
Area of prism: 2 × 120 + 555 + 592 + 740 = 2127
Solve the system by substitution y=6x and 7x-8y=-41
Answer:
x = 1
y = 6
Step-by-step explanation:
y = 6x --------------(I)
7x - 8y = -41 ------------(II)
Substitute y =6x in equation (II)
7x - 8*(6x) = -41
7x - 48x = -41 {Combine like terms}
-41x = -41
x = -41/-41
x = 1
Plug in x = 1 in equation (I)
y = 6*1
y = 6

MO = 8 units
MP = 4 units
Step-by-step explanation:
[tex] In\: \triangle MOP, \\
\angle P = 90\degree ... (given) \\
\angle M = 60\degree ... (given) \\
\therefore \angle O = 30\degree(3^{rd} \: \angle \: of\: \triangle) \\
Let \huge\purple {MO = x \: units}... (1)\\
\therefore MP = \frac{1}{2} \times MO\\(side\: opposite \: to\: 30\degree) \\\\

\therefore PO = \frac{\sqrt 3}{2} \times x\\\\
\huge\orange{\therefore PO = \frac{\sqrt 3}{2}x} \\\\
