Answer:
part a: is c
part b: $33.25
Step-by-step explanation:
PART A: I did 6x68.45=410.70
8x39.71=317.68
3x52.25=156.75
410.7+317.68+156.75=885.13
so the closest thing to it is c
PART B: i did
5x2.89=14.45
10x9.91=79.10
48x0.36=17.28
14.45+79.10+17.28=110.83
144.08-110.83=33.25
so the case of air fresheners was $33.25

This figure represents a small wooden container. What is the volume of the container? 66 cm³ 110 cm³ 132 cm³ 330 cm³
Answer:
66cm³
Step-by-step explanation:
To find the volume of this triangular prism, we have to find the area of the cross-section (in this case, the triangle) and multiply it by the length.
The area of the triangle is 1/2 × base × height:
1/2 × 4cm × 3cm = 6cm²
Next, multiply 6cm by the length:
6cm² × 11cm = 66cm³
Hope this helps!
Answer:
66cm is the correct answer
Step-by-step explanation:

Answer:
m = -1/2, y-intercept = -3, x-intercept = -6,0
Step-by-step explanation:
M is the gradient (or slope) and is always in front of the x coefficient. -1/2 in this case.
To find the y-intercept, we have to know that it is at the point where the graph passes through the y-axis. At this point x = 0. So just substitute 0 for x and solve for y to give -3.
To find the x-intercept, do the opposite. When the graph passes through the x-axis, y = 0. So when y = 0, x = -6

Guadalupe went shopping for a new pair of pants. Sales tax where she lives is 7%. The price of the pair of pants is $33. Find the total price including tax. Round to the nearest cent.
Answer:
Step-by-step explanation:
Image result for Guadalupe went shopping for a new pair of pants. Sales tax where she lives is 7%. The price of the pair of pants is $33. Find the total price including tax. Round to the nearest cent.
Step 1: take the total price and divide it by one plus the tax rate.
Step 2: multiply the result from step one by the tax rate to get the dollars of tax.
Step 3: subtract the dollars of tax from step 2 from the total price.
Pre-Tax Price = TP – [(TP / (1 + r) x r]
TP = Total Price.
The price of the pants after tax is $35.31
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: Price of the pants before tax= $33 and tax rate as 7%
Thus 7% of 33=2.31
Thus price after tax is equal to $33+$2.31=$35.31
Hence, The price of the pants after tax is $35.31

Use the information below to find the area of the other triangle
Answer:
130.68 mm²
Step-by-step explanation:
given 2 similar figures with ratio of sides = a : b , then
ratio of areas = a² : b²
here ratio of sides = 5 : 11 , then
ratio of areas = 5² : 11² = 25 : 121
let x be the area of Δ YPR , then by proportion
[tex]\frac{25}{27}[/tex] = [tex]\frac{121}{x}[/tex] ( cross- multiply )
25x = 3267 ( divide both sides by 25 )
x = 130.68
area of Δ YPR ≈ 130.68 mm²

Answer: 7/4 and 1 3/4
Step-by-step explanation:
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 4 = 16. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen quarters minus ten quarters = seven quarters.

A bat flies 180 feet in 20 seconds. At this rate, how far can it fly in 30 seconds?
Answer:
270
Step-by-step explanation:
To solve this, we use the unitary method.
Distance flown in 20 sec = 180
Distance flown in one sec = [tex]\frac{180}{20}[/tex] = 9
Thus, distance flow in 30 secs = 9 × 30 = 270

Samir works in a department store selling clothing. He makes a guaranteed salary of $300 per week, but is paid a commision on top of his base salary equal to 15% of his total sales for the week. How much would Samir make in a week in which he made $1275 in sales? How much would Samir make in a week if he made xx dollars in sales?
Answer:
$491.25 and 0.15xx + 300
Step-by-step explanation:
15%=0.15
$1275×0.15=$191.25 in sales
$191.25+$300=$491.25
He would make $491.25 a week in which he made 1275 in sales.
0.15xx + 300 = total earnings
He would make 0.15xx + 300 if he made xx dollars in sales

Answer:
If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos(θ) to get the side adjacent to the angle. If you have the non-hypotenuse side adjacent to the angle, divide it by cos(θ) to get the length of the hypotenuse.

the function represents the height y (in feet) of a grasshopper jumping straight up from the ground t seconds after the start of the jump.
After how many seconds is the grasshopper 1 foot off the ground
The grasshopper is 1 foot off the ground after ___ seconds
Answer:
1/4th of a second, or .25 seconds
Step-by-step explanation:
graphed it.
The grasshopper is 1 foot off the ground after 0.25 seconds.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
The given function is,
f(t) = -16t² + 8t
This represents the height y (in feet) of a grasshopper jumping straight up from the ground t seconds after the start of the jump.
We have to calculate the time t when f(t) = 1 foot.
-16t² + 8t = 1
-16t² + 8t - 1 = 0
This is a quadratic equation.
Solve using quadratic formula.
Discriminant = [tex]\sqrt{8^2-(4*-16*-1)}[/tex] = 0
t = (-8 ± 0) / (2 × -16) = -8/-32 = 0.25
Hence the time is 0.25 seconds when the grasshopper is at 1 foot.
Hence the grasshopper will be at 1 foot from the ground in 0.25 seconds.

A computer company claims that the lifespan of its batteries is 2. 7 years. The population standard deviation is 0. 85 years. A sample of 25 batteries was tested, and their mean lifespan was 3. 1 years. Using a 95% confidence level, determine if the company's claim is correct. Reject the null hypothesis. There is enough evidence to oppose the company's claim. Fail to reject the null hypothesis. There is enough evidence to oppose the company's claim. Reject the null hypothesis. There is not enough evidence to oppose the company's claim. Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim
Using the z-distribution, as we have the standard deviation for the population, it is found that the correct decision is given by:
Reject the null hypothesis. There is enough evidence to oppose the company's claim.
What are the hypothesis tested?At the null hypothesis, it is tested if the mean is of 2.7 years, that is:
[tex]H_0: \mu = 2.7[/tex]
At the alternative hypothesis, it is tested if the mean is different of 2.7 years, hence:
[tex]H_1: \mu \neq 2.7[/tex]
What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.[tex]\sigma[/tex] is the standard deviation of the sample.n is the sample size.In this problem, the values of the parameters are given by:
[tex]\overline{x} = 3.1, \mu = 2.7, \sigma = 0.85, n = 25[/tex]
Hence, the value of the test statistic is given by:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{3.1 - 2.7}{\frac{0.85}{\sqrt{25}}}[/tex]
[tex]z = 2.35[/tex]
What is the decision?Considering a two-tailed test, as we are testing if the mean is different of a value, with a significance level of 0.05, the critical value is of [tex]|z^{\ast}| = 1.96[/tex].
Since the absolute value of the test statistic is greater than the critical value, the correct decision is:
Reject the null hypothesis. There is enough evidence to oppose the company's claim.
More can be learned about the z-distribution at https://brainly.com/question/16313918
Answer:
Reject the null hypothesis. There is enough evidence to oppose the company's claim.
Step-by-step explanation:
The test statistic needs to fall within the rejection regions that are above and below the critical z-score associated with a 5% level of significance in order to reject the null hypothesis. Otherwise, we will fail to reject the null hypothesis.
