Find the value of x
Answer:
50?
Step-by-step explanation:
Answer:
x= 106
Step-by-step explanation:
The angle opposite 32 is also 32. Considering 44, the missing angle in that triangle would be 104. The angle to the left of 104 would be 76, and if you consider that angle 30 you are left with the measure of 74. X is the angle next to 74, so it makes sense for it to measure 106 because the values must add to 180, and even if it's not drawn to scale 106 looks accurate
Rita plans to make a call using a calling card. For each call, Rita has two options:
1. Pay $0.49, plus an additional $0.019 per minute.
2. Pay $0.059 per minute.
She predicts that her call will be minutes long. Which inequality represents the statement, "Rita would save money using the second option"?
The inequality that represents Rita saving money from the second option is 0.059x < 0.49 + 0.019x
How to determine the inequality that represents the statement?From the question, we have the following parameters that can be used in our computation:
1. Pay $0.49, plus an additional $0.019 per minute.2. Pay $0.059 per minute.These statements can be represented as
Option 1: y = 0.49 + 0.019x
Option 2: y = 0.059x
Where y is the total amount and x is the number of minutes
When she saves money, we have
Option 2 < Option 1
Substitute the known values in the above equation, so, we have the following representation
0.059x < 0.49 + 0.019x
Hence, the inequality is 0.059x < 0.49 + 0.019x

solve the equation for y: 1 / 3 x + y equals 4
Subtract (1/3)x from both sides of the equation.
(1/3)(x) - (1/3)(x) + y = -(1/3)(x) + 4
0 + y = -(1/3)(x) + 4
y = -(1/3)(x) + 4

A fox can run at a rate of 62 miles in 2 hours. A rabbit can run at a rate of 22 miles in 30 minutes. Which animal has the faster speed in miles per hour?
Answer:
The rabbit is faster, as it has a speed of 44 mph.
Step-by-step explanation:
Since the fox runs 62 miles in 2 hours, its speed can be determined by dividing the miles traveled by the time it took to do so. Thus, since 62/2 equals 31, its speed was 31 miles per hour.
In turn, the rabbit can travel 22 miles in half an hour. Following the same procedure, since 22 / 0.5 equals 44, its speed is 44 miles per hour.
Therefore, the rabbit is faster than the fox, since it has a speed of 44 mph versus 31 mph for the latter.
A can manufacturing company is designing a can of cat food to hold 5.5 oz, or about 163 cm3. They have written out that the equation for the surface area for a can with this volume is S=2πr2+163r. Explain why the equation is wrong and how to fix it.
Answer:
S = 2πr + 326/r
Step-by-step explanation:
Given
Volume = 163cm³
Required
Explain why S = 2πr² + 163r is not correct
The volume (V) of a cylinder is:
V = πr²h ----- (1)
And the surface area (S) is:
S = 2πr² + 2πrh ----- (2)
Make h the subject in (1)
h = V/πr²
Substitute V/πr² for h in (2)
S = 2πr² + 2πr(V/πr²)
Simplify the express in bracket
S = 2πr² + (2πrV)/(πr²)
S = 2πr² + 2V/r
Substitute 163 for V
S = 2πr + 2 * 163/r
S = 2πr + 326/r
The above shows the correct equation that solves the surface area and also shows how it was fixed by substituting proper values and following due process.

Show you work please
Answer:
The answer is 5/30
Step-by-step explanation:
The answer is 5/30 because when multiplying a fraction by a fraction you have to multiply the numerator by the numerator and the denominator by the denominator so if you multiply 5 by 1 you get 5 and when you multiply 6 by 5 you get 30 so the answer is 5/30

Answer:
Step-by-step explanation:
Formula for calculating interest is expressed as;
I = PRT/100
P is principal
R is the rate
T is the time
For first account
I = P(1)(6)/100
I1 = 0.06P1
For the second bank!
I2 =>P2(1)(4)/100
I2 = 0.04P2
If the total interest is $3520, then
I1+I2 = 3520
0.06P1+0.04P2 = 3520.... 1
If the Amount invested = $65000
P1+P2 =65000..... 2
Solve. 1 and 2 simultaneously
Eqn 2 × 0.06
0.06P1+0.06P2 = 3900.... 3
Subtract 1 from 3;
0.04P2-0.06P2 = 3520-3900
-0.02P2 = -380
P2 = 380/0.02
P2 = $19000
Get p1;
P1 = 65000-P2
P1 = 65000-19000
P1 = $46000
Hence $46000 was invested in the first account and $19000 in the second

C: {-14, 0.14)
D. {-21, -14, -7)
Answer:
B. {-21.-7. 7. 21)
Step-by-step explanation:
The set made up of odd numbers and multiples of 7 is given as;
{-21.-7. 7. 21)
Multiples of 7 are usually those numbers where 7 is factor.
Odd numbers are numbers that cannot be divide by 2.
So, the most fitting answer is B.

A) Slope=2
B) Slope= 1/2
C)Slope=-4
Answer:
Answer choice C
Step-by-step ex. 4 is the greatest number out of explanation:
The greater the absolute value is, the steeper it is. In this case, the absolute value of -4 is positive 4 since the absolute value shows how far a number is a ways from zero and is always positive. 4 is the largest number out of all of these choices which means it is the steepest slope.
