Answer:
1. C(d)=0.69x+25.95
2. C(d)=0.69(57)+25.95
[0.69 times 57 is 39.33]
= 65.28 dollars
3. 136.3 miles
Step-by-step explanation:
For the first question....
Since this is a function, we have to start with C(d). Even if you drive 0 miles, you still have to pay $25.95 just for renting the truck, so that is constant. For every mile you drive, you pay $0.69. Since we don't know how far anyone is going to drive, we will put 'x' as the amount of miles driven. The number of miles driven (x) multiplied by 0.69 will be the cost of that. The final function would be C(d)=0.69x+25.95.
For the second question....
We know the general function now, so driving 57 miles would mean substituting "x" for 57, and doing the multiplication (if necessary), 0.69 times 57 equals 39.33 (the dollar amount for driving 57 miles, not including the starting fee of 25.95)
Doing the math, you can get $65.28 (39.33+25.95).
For the third question...
If we have a budget, we know that C(d) is the amount of money spent, so we'll substitute the budget (120) for that. We'll solve the equation for x from there, and should get 136.3 miles (rounded to the nearest hundredth).

Select all of the true statements below.
Answer:
a and d are both true. The rest are not.
Step-by-step explanation:
1 and 6 are like terms. They are both integers. They can be combined. This statement is true.
7 is a numerical coefficent. This statement is true.
===========================================
The others are all false for one reason or another
b is false. The factor is made up of 2 terms not 3. 7a is one term.
c is false. "a" is a variable. So the whole term can be anything.
e is false. 7a + 2 is a factor
f is false. There are two true statements.

Given sides a-10, b=5 and angle ZA-100°. Find the corresponding value for ZB. Options: A 60° B 5° D -29.5° C 29.5°
The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. The measure of the ∠B=29.5°.
What is Sine rule?The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,
[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}[/tex]
where Sin A is the angle and α is the length of the side of the triangle opposite to angle A,
Sin B is the angle and β is the length of the side of the triangle opposite to angle B,
Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.
Given that sides a=10, b=5 and the measure of the ∠A=100°. Therefore, the using the sine law,
[tex]\rm \dfrac{Sin\ A}{a} = \dfrac{Sin\ B}{b}[/tex]
[tex]\rm \dfrac{Sin\ 100^o}{10} = \dfrac{Sin\ B}{5}\\\\\rm \dfrac{(Sin\ 100^o) \times 5}{10} = Sin\ B\\\\Sin\ B = 0.04924\\\\\angle B = 29.498^o \approx 29.5^o[/tex]
Hence, the measure of the ∠B=29.5°.

Find the standard equation of the circle with center (5, -3
and with a point on the circle (-3,3)
Answer:
○ C
Explanation:
Accourding to one of the circle equations, [tex]\displaystyle (x - h)^2 + (y - k)^2 = r^2,[/tex]the centre of the circle is represented by [tex]\displaystyle (h, k).[/tex]Moreover, all negative symbols give you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must pay cloce attention to which term gets which symbol. Another thing you need to know is that the radius will ALWAYS be squared, so no matter how your equation comes about, make sure that the radius is squared. Now, in case you did not know how to define the radius, you can choose between either method:
Pythagorean Theorem
[tex]\displaystyle a^2 + b^2 = c^2 \\ \\ 6^2 + 8^2 = r^2 \hookrightarrow 36 + 64 = r^2 \hookrightarrow \sqrt{100} = \sqrt{r^2} \\ \\ \boxed{10 = r}[/tex]
Sinse we are dealing with length, we only desire the NON-NEGATIVE root.

A party hat shaped like a cone requires about 66 square inches ( Surface Area ) of paper to make. If the slant height is 7 inches, how wide is the hat?
Answer:
6 inches
Step-by-step explanation:
Solving
Curved Area = π x r x slant height66 = 3.14 x 7 x rr = 66/21.98 ≅ 3 inchesWidth of the hat
Diameter of the cone2 x Radius2 x 3 = 6 inchesAnswer:
6.00 in (nearest hundredth)
Step-by-step explanation:
Lateral surface area = surface area excluding the bases(s)
Lateral surface area of a cone = [tex]\pi rs[/tex]
(where r is the radius and s is the slant height)
Given:
lateral surface area ≈ 66 in²slant height (s) = 7 in[tex]\implies 66= \pi r \cdot 7=7 \pi r[/tex]

Suppose you draw a card from a well-shuffled deck of 52 cardsWhat is the probability of drawing a 2 or a queen?
[tex]\frac{2}{13}[/tex]
Step-by-step explanation:Probability is finding the chance that some specific outcome will occur. In this case, we are looking for the probability of one of two outcomes.
Equally Likely Outcomes
When drawing a card from a well-shuffled deck, all outcomes (cards) are equally likely to be drawn. Each card was a 1/52 probability of occurring.
Probability of Two Outcomes
In a deck of cards, there are 4 cards of each number. This means that the probability of drawing a 2 is 4/52, the same for a queen.
So, to find the probability of one of the two desired outcomes is equal to adding the probabilities together.
[tex]\frac{4}{52} +\frac{4}{52} =\frac{8}{52}[/tex]This fraction can then be simplified further:

The fox observed that the tortoise plodded along at a rate of 20 meters per minute throughout the 1000-meter race.
1. Complete the table below indicating the distance traveled by the tortoise in the time elapsed.
The values that are required to complete the table above indicating the distance traveled by the tortoise in the time elapsed are calculated below.
How to calculate the distance traveled?Mathematically, the distance traveled by the tortoise would be calculated by using this formula:
Distance = speed (rate) × time
When time = 1 min, we have:
D₁ = 20 × 1
D₁ = 20 meters.
When time = 2 min, we have:
D₂ = 20 × 2
D₂ = 40 meters.
When time = 3 min, we have:
D₃ = 20 × 3
D₃ = 60 meters.
When time = 4 min, we have:
D₄ = 20 × 4
D₄ = 80 meters.
When time = 5 min, we have:
D₅ = 20 × 5
D₅ = 100 meters.
When time = 6 min, we have:
D₆ = 20 × 6
D₆ = 120 meters.
When time = 7 min, we have:
D₇ = 20 × 7
D₇ = 140 meters.
When time = 10 min, we have:
D₁₀ = 20 × 10
D₁₀ = 200 meters.
When time = 15 min, we have:
D₁₅ = 20 × 15
D₁₅ = 300 meters.
When time = 20 min, we have:
D₂₀ = 20 × 20
D₂₀ = 400 meters.
When time = 25 min, we have:
D₂₅ = 20 × 25
D₂₅ = 500 meters.
When time = 30 min, we have:
D₃₀ = 20 × 30
D₃₀ = 600 meters.
When time = 35 min, we have:
D₃₅ = 20 × 35
D₃₅ = 700 meters.
When time = 40 min, we have:
D₄₀ = 20 × 40
D₄₀ = 800 meters.
When time = 50 min, we have:
D₅₀ = 20 × 50
D₅₀ = 1,000 meters.

The commissioner of the state police is reported as saying that about 10% of reported auto thefts involve owners whose cars haven't really been stolen. What null and alternative hypotheses would be appropriate in evaluating this statement made by the commissioner?
A. H0: p ≥ 0.10 and H1: p < 0.10
B. H0: p ≤ 0.10 and H1: p > 0.10
C. H0: p > 0.10 and H1: p ≤ 0.10
D. H0: p = 0.10 and H1: p ≠ 0.10
The appropriate null and alternate hypotheses are (d) H0: p = 0.10 and H1: p ≠ 0.10
How to determine the hypotheses?From the question, we understand that:
The proportion of reports that have their cars stolen is given as 10%
Null hypothesis is represented with the equality sign.
So, the null hypothesis is H0: p = 0.10
The alternate hypothesis is represented with the unequal sign.
So, the alternate hypothesis is H1: p ≠0.10
Hence, the appropriate hypotheses are (d) H0: p = 0.10 and H1: p ≠ 0.10
