Its not 67%
It is 0.666666667

23400 x 8/100 = 1872 = the loss
1872 : 12 = 156= the loss each month
156/1872*100% = 8,33 % then round it

attashe74 [19]

Question says that Wong’s Garage buys quarts of motor oil by the gross (144 units) for $0.75 per quart.

That means cost of 1 quart motor oil = $0.75

Now it says that Wong’s changes the oil in customers’ cars and marks up the oil 175% of the cost.

So that means selling price of the 1 quart of the motor oil

= 175% of original price

= 175% of 0.75

= 1.75* 0.75

= 1.3125

Which is approx $1.31

Hence final answer is $1.31

Which of the following could be the ratio of the length of the longer leg of a 30-60-90 triangle to the length of its hypotenuse

Aliun [14]

Answer:

Option C is correct.

Ratio of longer leg to hypotenuse is; $\sqrt{3} : 2$

Step-by-step explanation:

This is the special right angle triangle 30°-60°-90° as shown below in the figure.

The side opposite the 30° angle is always the shortest because 30 degrees is the smallest angle.

The side opposite the 60° angle will be the longer leg, because 60 degrees is the mid-sized degree angle in this triangle.

Finally , the side opposite the 90° angle will always be the largest side(Hypotenuse) because 90 degrees is the largest angle.

In 30°−60°−90° right triangle,

the length of the hypotenuse is twice the length of the shorter leg,also
the length of the longer leg is $\sqrt{3}$ times the length of the shorter leg.

Then:

the sides are in proportion i.e, $1:\sqrt{3} :2$

Therefore, the ratio of the length of the longer leg to the length of its hypotenuse is: $\sqrt{3} : 2$

A building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18pi meters. Wh

ella [17]

Answer

Circumference(C) of a circle is given by:

$C = 2\pi r$

where r is the radius and value of $\pi = 3.14$

As per the given statement:

A building engineer analyzes a concrete column with a circular cross section.

The circumference of the column is $18 \pi$ meters.

then;

$18 \pi= 2\pi r$

Divide both sides by $2 \pi$ we have;

9 = r

or

r = 9 meters

We have to find the area of the cross section of the column

Area of a circle is given by:

$A = \pi r^2$

then;

$A = \pi \cdot 9^2 = 81 \pi$ meter square.

therefore, the area A of the cross section of the column is $81 \pi$ meter square.

A study was conducted to determine the percent of children that want to grow up work in the same career as a parent. In a sample

Irina-Kira [14]

Answer:

Step-by-step explanation:

From the information given,

Number of sample, n = 200

Probability of success, p = 43/100 = 0.43

q = 1 - p = 1 - 0.43

q = 0.57

For a confidence level of 95%, the corresponding z value is 1.96.

The formula for determining the error bound for the proportion is

z × √pq/n

= 1.96 ×√(0.43 × 0.57)/200

= 1.96 × 0.035 = 0.0686

The upper boundary of the population proportion is

0.43 + 0.0686 = 0.5

The lower boundary of the population proportion is

0.43 - 0.0686 = 0.4

The error in the solution is

phat = 0.43/200 = 0.00215

Also,

[-0.0043, 0.0086] is wrong

Hank bought 5 meters of ribbon for $4. The ribbon costs -$0.008, 0.08, $0.8- per -millimeter, centimeter, kilometer-. Choose one

aleksandrvk [35]

To determine the cost of each meter of the ribbon, we divide the cost for 5 meters of ribbon by 5. That is,
x = $4 / 5
where x is the cost of each meter. Simplifying will give us an answer of $0.8/m. Converting this to per mm.
($0.8/m) x (1 m/ 1000 mm)
= $0.0008/mm
