Answer:
x = 48 degrees
Step-by-step explanation:
Every triangle has an interior angle of 180 degrees
to find x, take the known angles and add them together:
47 + 85 = 132
now take the sum and subtract it from 180;
180 - 132 = 48
x = 48 degrees

The cone and cylinder below have equal surface area
Answer:
Option B, False
Step-by-step explanation:
Step 1: Get the surface area formulas for both shapes
Surface Area Formula for Cone: [tex]A = \pi * r(r + \sqrt{h^{2} + r^{2}})[/tex]
Surface Area Formula for Cylinder: [tex]A = 2\pi rh+2\pi r^{2}[/tex]
Step 2: Plug in the values and solve
Cone: [tex]A = \pi * r(r + \sqrt{(3r)^{2} + r^{2}})[/tex]
Cone: [tex]A = \pi r^{2} + \pi \sqrt{10}r^{2}[/tex]
Cylinder: [tex]A = 2\pi r*r+2\pi r^{2}[/tex]
Cylinder: [tex]A=4 \pi r^{2}[/tex]
Step 3: Compare
[tex]\pi r^{2} + \pi \sqrt{10}r^{2}\neq 4 \pi r^{2}[/tex]
They are not equal, therefore the answer is False.
Answer: Option B, False

Answer:
121
Step-by-step explanation:
Number of sides = n = 7
Sum of all the interior angles = (n -2)*180 = (7-2) *180
= 5 *180
= 900
x + 125 + 119 +117 +145 + 133 + 140 = 900
x + 779 = 900
x = 900 - 779
x = 121
Answer:
x = 121°
Step-by-step explanation:
The formula to find the sum of interior angles of a polygon is:
180 ( n - 2 )
Here,
n ⇒ number of sides ⇒ 7
First, let us find the sum of the interior angles of the polygon.
180 ( n - 2 )
180 × ( 7 - 2 )
180 × 5
900°.
Accordingly, let us make an expression to find the value of x.
145 + 133 + 140 + 125 + 119 + 117 + x = 900
Let us solve for x now.
779 + x = 900
Subtract 779 from both sides.
x = 900 - 779
x = 121

Answer:
C) $3572
Step-by-step explanation:
The simple interest formula is ...
I = Prt
where P is the amount invested at annual rate r for t years.
To find the value of P, we can divide by rt:
P = I/(rt)
Filling in the given information, we have ...
P = $500/(0.035×4) = $500/0.14 ≈ $3572
$3572 must be invested to earn $500 interest in 4 years.

x=10 y=15
x= 30 y=25
x=16 y=21
x= 32 y= 26
Answer:
the last one
Step-by-step explanation:
32+26=58
32-26=6
Answer:
The first number is 32 and the second is 26
Step-by-step explanation:
Let the two numbers be represented by x and y
1) x + y = 58
2) x - y = 6
x = 6 + y, we'll use put this in the first equation.
x + y = 58
6 + y + y = 58
6 + 2y = 58
2y = 58 - 6
2y = 52
2. 2
y=26, now let's find x, again use the first equation
x + y = 58
x + 26 = 58
x = 58 - 26
x = 32
Ramon paid a flat fee of $269.50 for a year's worth of vet visits for his 4 cats. He made 14 visits during the year. What was the average cost per vet visit?
Answer:
The average cost per vet visit was $19.25.
Step-by-step explanation:
From the information given, you can find the average cost per visit by dividing the total amount paid for a year's worth of vet visits by the number of visits:
269.50/14= $19.25
According to this, the answer is that the average cost per vet visit was $19.25.

A portable CD player is on sale.
It is advertised as, “Save $20. You pay
$49.99."
a) What is the regular price?
b) What is the percent decrease?
find the slope of the line passing through the points (5, 6) and (5,-8)
Answer:
Undefined
Step-by-step explanation:
Slope is equal to the change in y over the change in x.
m = (y₂ - y₁) / (x₂ - x₁)
Let your points (5, 6) be (x₁, y₁) and (5,-8) be (x₂, y₂). Therefore you have
m = (-8 - 6) / (5 - 5) = -14 / 0
Dividing by zero will lead you to have an undefined slope

1.) The graph of g(x) = ax? opens downward and is narrower than the graph of f(x) = x? Which of the following
could be the value of a?
a. 5
b. 0.5
C. -5
d. -0.5
Answer:
C. -5
Step-by-step explanation:
for g(x) =ax and f(x) = x, both are linear function. There is nothing to be upward or downward and both are lines nothing to compare its narrowness.
If g(x) = ax² vs f(x) = x²
Then a = -5 is the answer (-: downward and 5: vertical stretch)
