Write the scale of the drawing as a fraction. Put the shorter length in the numerator.
[tex] \frac{7 \: cm}{1 \: cm} \\ [/tex]
First convert the denominator to the same units as the numerator. Write an equivalent fraction with centimeters in the denominator. Since 1 meter is equal to 100 centimeters, multiply the denominator by 100 to get centimeters in the denominator.
[tex] \frac{7 \: cm}{100 \: cm} = \: \frac{7}{100} \\ [/tex]
Write the scale factor as a ratio, using a colon
7/100 → 7:100
The scale factor is 7:100.

Find the surface area of the cylinder. Round your answer to the nearest tenth.
Answer:
62.8
Step-by-step explanation:
The formula of finding the volume of a cylinder v= pi*r^2*h
So substitute the values:
r is 2, and h is 5
v=pi*2^2*5
Then solve the equation:
v=pi*4*5
v=pi*20
v=62.8 (I multiplied 20 by 3.14, or pi)
So the answer is 62.8

Answer:
[tex]x = \frac{19-2y}{3}[/tex]
[tex]y=-\frac{3x+19}{2}[/tex]
Step-by-step explanation:
4x + y = 22
y = x - 3
4x + y + y = 22 + x - 3
4x + 2y = 19 + x
4x - x + 2y = 19 + x - x
3x + 2y ÷ 3 = 19 ÷ 3
[tex]x = \frac{19-2y}{3}[/tex]
[tex]y=-\frac{3x+19}{2}[/tex]
Answer:
a)Let's solve for x.
4x+y=22
Step 1: Add -y to both sides.
4x+y+−y=22+−y
4x=−y+22
Step 2: Divide both sides by 4.

Amy has a rectangular garden that is 23 feet wide. If the length of the garden is 12 feet, what is the length of its diagonal, in feet? Round to the nearest tenth
Answer:
25.9 feet
Step-by-step explanation:
If you split a rectangle into 2 pieces with a diagonal, each piece will be a right triangle
Therefore we can use the pythagorean theorem to solve this problem
The two legs of the right triangle will be 23 and 12
The formula is a^2 +b^2=c^2
c^2 is the diagonal squared ( the hypotenuse)
So:
12^2+23^2=c^2
144+529=c^2
673=c^2
To find just c we need to find the square root of 673, rounded to the nearest tenth
[tex]\sqrt{673}=25.9[/tex]
(the equation is rounded)
So the diagonal is 25.9
Y-intercept = 5
Slope = 3
Answer:
the equation as intercept form is
y = 3x + 5

Answer:
42.39 sq.cm
Step-by-step explanation:
Ф = 135°
r = 6 cm
Area of the sector = [tex]\frac{theta}{360}*\pi *r^{2}\\[/tex]
[tex]= \frac{135}{360}* 3.14 *6 * 6\\\\= \frac{135}{10}*3.14\\\\= 27 * 1.57\\\\=42.39[/tex]
The area of sector bounded by 135 ° arc is 42.42 cm ².
Step-by-step explanation:
Given :-Radius of the circle , r = 6 cm
Angle of the circle, θ = 135 °
To Find :-Area of circle bounded by a 135 ° arc.
Solution :-We know that
[tex]\small \sf \: Area \: of \: sector \: = \frac{θ}{360} \: \times \pi \times r {}^{2} \\ [/tex]
Substitute the values of r and θ , we get
Area of sector =
[tex]\small \sf \: Area \: of \: sector \: = \frac{135 °}{360} \: \times \pi \times {6cm}^{2}\\ [/tex]
[tex]\small \sf \: Area \: of \: sector \: = \frac{135°}{360} \: \times \frac{22}{7} \times 6cm \times 6cm \\ \\ \small \: \sf Area \: of \: circle \: = \frac{135}{360} \times \frac{22}{7} \times 36cm {}^{2} \\ \sf \: \: = \frac{135}{10} \times \frac{22}{7} \\ \sf \: = 42.42cm \: {}^{2} [/tex]
Therefore, The area of sector bounded by 135 ° arc is 42.42 cm ².

Answer:
Amber has a total of $1225.54 after 10 years. Jin has a total of $1225.35 after 10 years. So, Amber earns $0.19 more
Step-by-step explanation:
A: Amber
First, convert 8 percent to r as a decimal
r = R/100
r = 8/100
r = 0.08 rate per year
P = Principal
e = 2.71828(mathematical constant)
t = time
Then solve the equation for A
A = P*e^(r*t)
A = 1,000.00(2.71828)^(0.08)(10)
A = $2,225.54
The total amount accrued, principal plus interest, with compound interest on a principal of $1,000.00 at a rate of 8% per year compounded continuously over 10 years for Amber is $2,225.54.
J: Jin
First, convert 8 as a percent to r as a decimal
r = R/100
r = 8/100
r = 0.08 rate per year
n = 365 days
Then solve the equation for A
A = P(1 + r/n)^n*t
A = 1,000.00(1 + 0.08/365)(365)(10)
A = 1,000.00(1 + 0.000219178)(3650)
A = $2,225.35
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $1,000.00 at a rate of 8% per year compounded 365 times per year over 10 years for Jin is $2,225.35.
$2,225.54-1000=A($1225.54)
$2,225.35-1000=J($1225.35)

Step-by-step explanation:
write the standard form of the equation of a circle with a radius of 1 and a center of (-7,1)
Answer:
(x + 7)² + (y - 1)² = 1
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 7, 1) and r = 1 , then
(x - (- 7) )² + (y - 1)² = 1² , that is
(x + 7)² + (y - 1)² = 1
Kalon has $175 and needs to save atleast $700 for a computer.if he can save $35 per week, what is the minimum number for of weeks kalon will need to reach his goal
Answer:
15 weeks
Step-by-step explanation:
First, calculate the total that is needing to be saved not including the money she already has.
So 700 minus 175 is 525.
Next, to find the number of weeks, divide 525 by 35 which gives you 15 even.
So if Kalon continues to save $35 a week, it will take him 15 weeks to reach his goal of $700.

The cost of 10 donuts and 2 cakes is the same. If the cost of 3 cakes and 5 donuts is $8, find the cost of a cake.
Answer:
$2
Step-by-step explanation:
Let the cost of a donut and a cake be $d and $c respectively.
10d= 2c
Dividing both sides by 2:
5d= c -----(1)
3c +5d= 8 -----(2)
Substitute (1) into (2):
3c +c= 8
Simplify:
4c= 8
Divide both sides by 4:
c= 8 ÷4
c= 2
∴ The cost of a cake is $2.

The denominator of a fraction is 4 more than twice its numerator. Denominator becomes 12 times the numerator, if both the numerator and the denominator are reduced by 6. Find the fraction.
Answer: [tex]\dfrac{6}{26}[/tex]
Step-by-step explanation:
Given
Denominator is 4 more than twice its numerator
Suppose the numerator is x. So, it follows above condition, fraction becomes
[tex]\Rightarrow \dfrac{x}{2x+4}[/tex]
If both numerator and denominator are reduced by 6, they become equal
[tex]\Rightarrow 12(x-6)=2x+4-6\\\Rightarrow 12x-72=2x-2\\\Rightarrow 10x=70\\\Rightarrow x=7[/tex]
The fraction is
[tex]\Rightarrow \dfrac{x}{4x+2}=\dfrac{6}{4\times 6+2}\\\\\Rightarrow \dfrac{6}{26}[/tex]

How does the graph of f(x) = |x| compare with the graph of g(x) = −2|x|? Select all that apply.
A. The graph of g is a vertical compression of the graph of f.
B. The graph of g is a vertical stretch of the graph of f.
C. The graph of g is a reflection over the x-axis of the graph of f.
Answer:
option A
Step-by-step explanation:
y = k . f( x )
• if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically stretched by multiplying each of its y-coordinates by k.
• if 0 < k < 1 (a fraction), the graph is f (x) vertically shrunk (or compressed) by multiplying each of its y-coordinates by k.
• if k < 0, the vertical stretch or shrink is followed by a reflection across the x-axis.
Given g(x ) = - |x |
= -1 × f(x)
k < 0 , therefore the graph g (x) is a vertical shrink ( or compression ) of graph f

A retailer sells a refrigerator for a list price of $1,200. The retailers cost was $850. What is the percentage of the markup?
Answer:
41%
Step-by-step explanation:
1200-850=350
350 is the markup, now we need the percentage
the orginal price was 850 so we just need to divide 350 by 850
we get 0.4117...
convert that to a percentage and we have 41% markup
While attempting to multiply the expression (3x + 7)" a student made mistakes. Explain and write the correct way.
Answer:
9x²+42x+49
Step-by-step explanation:
that is not the correct way to foil.
the correct way would be (3x+7)²= (3x+7)(3x+7)
simplifying that would give us 9x²+42x+49
his mistake was multiplying wrong because he did not foil

Answer:
m ∠S = 43°
Step-by-step explanation:
Exterior angle = Sum of opposite interior angles
(6x)° = 77° + (2x + 3)°
6x = 77 + 2x + 3
6x - 2x = 77 + 3
4x = 80
x = 20
m ∠S = (2x + 3)° = 2(20) + 3 = 40 + 3 = 43°
Answer:
∠ S = 43°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ PQR is an exterior angle of the triangle, then
6x = 77 + 2x + 3 ( subtract 2x from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
Then
∠ S = 2x + 3 = 2(20) + 3 = 40 + 3 = 43°
