Answer:
The area consists of 3 semi-circles and a square
A) A = 3*1/2πr² + a²
A = 3/2*3.14*(10/2)² + 10² = 217.75 m²B)
A = 3/2*22/7*5² + 10² = 217.85 m²C)
217.75*8 = $1742What is the slope-intercept equation of the line below?
y-intercept = (0, 2)
slope =
11
Answer:
If the slope is 11, and the y-intercept is (0, 2), the answer is: y = 11x + 2.
The picture says the slope is -1/4. The answer to the question in the picture is: y = -1/4x + 2.
Step-by-step explanation:
Slope form is
y = mx + b.
m is the slope.
b is the y value of y intercept.
hamster runs in its wheel whose r=3. The wheel completes 9.2 rev/sec.what is the linear velocity
The linear velocity of the hamster is 173.328 m/s.
What is linear velocity?Linear velocity is the rate of change of displacement along a straight line.
To calculate the linear velocity of the hamster, we use the formula below.
Formula:
v = ωr............ Equation 1Where:
v = linear velocityr = radius of the wheelω = Angular velocityFrom the question,
Given:
r = 3 mω = 9.2 rev/sec = (9.2×2π) rad/s = 57.776 rad/sSubstitute these values into equation 1
v = 3(57.776)v = 173.328 m/sHence, The linear velocity of the hamster is 173.328 m/s.

At a Marine Corps military base there is a barbershop where the actual output from each chair is 12 haircuts per hour. It operates with an efficiency of 85%. If the base needs to have 650 haircuts a day how many barber chairs should there be if the barber shop is open 10 hours per day
Answer:
Barbers= 5.41= 6 barbers
Step-by-step explanation:
Giving the following formula:
Haircuts per hour= 12
Number of hours= 10
Haircuts needed= 650
First, we need to calculate the number of haircuts each barber can make per day:
Haircuts per barber a day= 12*10= 120 haircuts
Now, the number of barbers needed:
Barbers= total haircuts / haircuts per day
Barbers= 650/120
Barbers= 5.41= 6 barbers

In a random sample of 500 young men between the ages of 18 and 20, the mean NAEP math score is 272. Do we have evidence to support the claim that young men nationwide have a mean score below 275

Question 1: The National Assessment of Educational Progress (NAEP) is administered annually to 4th, 8th, and 12th graders in the United States. On the math assessment, a score above 275 is considered an indication that a student has the skills to balance a checkbook. In a random sample of 500 young men between the ages of 18 and 20, the mean NAEP math score is 272 with standard deviation of 78.
Do we have evidence to support the claim that young men nationwide have a mean score below 275. The level of significance is 5%
Answer:
p-value ( 0.2 ) > significance level (0.05 )
Fail to reject H₀ at ∝ = 0.05
Therefore, We do not have enough evidence to conclude that the mean score is less than 275 for young men nationwide.
Step-by-step explanation:
Given the data in the question;
Null hypothesis H₀ : μ = 275
Alternative hypothesis Hₐ : μ < 275
mean x' = 272
standard deviation σ = 78
sample size n = 500
Test Statistics
z = (x'-μ) / (σ /√n )
we substitute
z = (272-275) / (78 /√500 )
z = -3 / 3.488266
z = - 0.86
from table;
p-value = 0.19489 ≈ 0.2
Hence; p-value ( 0.2 ) > significance level (0.05 )
Fail to reject H₀ at ∝ = 0.05
Therefore, We do not have enough evidence to conclude that the mean score is less than 275 for young men nationwide.

Decimal Form:
2.62144 ⋅ 10 / 13
Step-by-step explanation:
A boat is 170 inches long. A truck is 80% longer than the truck.How long is the truck?
250 inches
213 inches
306 inches
136 inches
15 points <33
Answer:
306 inches
Step-by-step explanation:
80% = 0.8
170 inches × 80% = 170 × 0.8 = 136
The truck is 80% longer than the boat. 80% of the boat is 136.
So, the boat is 170 inches + 136 inches = 306 inches.
Answer:
C) 136 inches.
Step-by-step explanation:
To find this just do the equation:
170 x 0.8 = ?
This equation tells use how much 80% of 170 is. Also, before doing an equation like this, change the percentage into a decimal like 80% to 0.8.
So,
170 x 0.8 = 136
170 + 136 = 306
So the boat is 306 inches.

Find the conjugate and product of the following surds
2i + 9
Answer:
The conjugate of 2i + 9 = -2i + 9
Product of (2i+9) and (2i+9) is 36i + 77
Step-by-step explanation:
Given - 2i + 9
To find - Find the conjugate and product of the following surds
Proof -
We know that,
The sum and difference of two simple quadratic surds are said to be conjugate surds to each other.
To find a complex conjugate, simply change the sign of the imaginary part (the part with the i ).
So,
The conjugate of 2i + 9 = -2i + 9
Now,
Product of surd (2i+9) is
(2i+9)(2i+9) = 2i(2i) + 2i(9) + 9(2i) + 9(9)
= 4i² + 18i + 18i + 81
= -4 + 36i + 81 { because i² = -1 }
= 77 + 36i
⇒Product of (2i+9) and (2i+9) is 36i + 77
solve the system using substitution x=-4y y=2x+9
Answer: x=-4
Step-by-step explanation:
Given
x=-4y
y=2x+9
Rephrase equation to find y value in terms of x
y=-x/4
y=2x+9
Use substitution (substitute value of y)
2x+9=-x/4
Multiply -4 on both sides
-4(2x+9)=-4(-x/4)
-8x-36=x
Add 8x on both sides
-8x-36+8x=x+8x
-36=9x
Divide 9 on both sides
-36/9=9x/9
x=-4

The weight of a soccer ball is normally distributed with a mean of 0.43 kg and a standard deviation of 0.01 kg. Suppose 800 different soccer balls are in a warehouse. About how many soccer balls weigh more than 0.45 kg?
A. 12
B. 20
C. 24
D. 40
Answer:
Answer is b) 20.
Step-by-step explanation:
Mean is 0.43 kg.
0.43+0.1+0.1= 0.45
0.45 is two standard deviation above.
All that are below mean is 50%,
Two standard deviation above is 95%/2=47.5%
50%+47.5% =97.7% are balls that are less than 0.45 kg.
100%-97.7%=2.5% balls that are more than 0.45 kg
2.3%=0.025
800*0.025 = 20 soccer balls weigh more than 0.45 kg

Answer:
Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°.
