Answer:
[tex]Time = 1.2\ hours[/tex]
Step-by-step explanation:
Given
[tex]Speed= 85\ miles/hour[/tex]
Required
Determine the time for 102 miles
In this case, we make use of Speed formula as follows:
[tex]Speed = \frac{Distance}{Time}[/tex]
This gives:
[tex]85 = \frac{102}{Time}[/tex]
Solve for Time
[tex]Time = \frac{102}{85}[/tex]
[tex]Time = 1.2\ hours[/tex]
Hence, the time needed is 1.2 hours

What is the equation of the line that passes through the point (-5,-2) and has a slope of -6/5
Answer:
The answer is
[tex]y = - \frac{6}{5} x - 8 \\ [/tex]Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1) \\ [/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (-5,-2) and the slope is - 6/5
The equation of the line is
[tex]y + 2 = - \frac{6}{5} (x + 5) \\ y + 2 = - \frac{6}{5} x - 6 \\ y = - \frac{6}{5} x - 6 - 2[/tex]
We have the final answer as
[tex]y = - \frac{6}{5} x - 8 \\ [/tex]

Rewrite in simplest terms: (3x + 2) + (-10x – 3)
Answer:
[tex]\boxed {\tt -7x-1}[/tex]
Step-by-step explanation:
We are given the expression:

Combine like terms.
The terms with variables can be combined, then the terms without variables (constants) can be combined.
[tex](3x+-10x)+(2+-3)[/tex]
[tex](3x-10x)+(2-3)[/tex]
Subtract 10x from 3x.

williams only has 1 3/4cups of flour ,so he only make 2/3 0f a batch of biscuits. how much flour is needed for a full batch of biscuits?
Answer:
2 5/8 cups of flour
Step-by-step explanation:
Use a proportion.
1 3/4 cups of flour is to 2/3 of a batch as x cups of flour is to 1 batch.
1 3/4 : 2/3 = x : 1
2/3 x = 1 3/4 * 1
2/3 x = 1 3/4
2/3 x = 7/4
3/2 * 2/3 x = 3/2 * 7/4
x = 21/8
x = 2 5/8
Answer: 2 5/8 cups of flour

Answer:[tex] - 3[/tex]
Answer:
- 3
Step-by-step explanation:
Using the rules of exponents/ radicals
[tex]a^{\frac{m}{n} }[/tex] ⇔ [tex]\sqrt[n]{a^{m} }[/tex]
[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]
Thus
[tex]64^{\frac{1}{3} }[/tex] = [tex]\sqrt[3]{64}[/tex] = 4
[tex]64^{-\frac{1}{3} }[/tex] = [tex]\frac{1}{4}[/tex]
[tex]64^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{64^{2} }[/tex] = 4² = 16
Substituting values into the given expression
[tex]\frac{1}{4}[/tex] (4 - 16)
= [tex]\frac{1}{4}[/tex] × - 12

3. Error Analysis Isabel says that the equation x - 2 = -(x - 2) has no
solution because a number can never be equal to its opposite. Explain the
error Isabel made
Given:
The equation is
[tex](x-2)=-(x-2)[/tex]
Isabel says that the given equation has no solution because a number can never be equal to its opposite.
To find:
Isabel's mistake.
Solution:
Her reason "a number can never be equal to its opposite" is not correct.
Zero is a number that can be equal to its opposite.
So, the given equation has solution for which LHS=RHS=0.
We have,
[tex](x-2)=-(x-2)[/tex]
[tex]x-2=-(x)-(-2)[/tex]
[tex]x-2=-x+2[/tex]
Add x and 2 on both sides.
[tex]x-2+x+2=-x+2+x+2[/tex]
[tex]2x=4[/tex]
Divide both sides by 2.
[tex]x=\dfrac{4}{2}[/tex]
[tex]x=2[/tex]
So, the given equation has a solution x=2.
Use a calculator to see what would happen if you used a credit card to pay the minimum monthly payment. Calculate using the following information: Cost of computer (balance): $600 Annual percentage rate (APR): 12.9% Total duration of payments: 2 years Use the simple interest formula: A = (P)(r)(t) If you make only the minimum payment each month, what will the total cost of the computer be?
Answer:
C. $755 i got it right
Step-by-step explanation:
If you make only the minimum payment each month, the total cost of the computer will be $755.00, which is $155 more than the original cost of the computer ($600).
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To calculate the total cost of the computer if you make only the minimum payment each month, we need to use the simple interest formula:
A = P(1 + rt)
where A is the total amount paid, P is the principal or balance, r is the annual interest rate expressed as a decimal, and t is the time in years.
P = $600
r = 12.9% or 0.129 (annual interest rate)
t = 2 years
To find the monthly interest rate, we divide the annual interest rate by 12 (the number of months in a year):
Monthly interest rate = 0.129 / 12 = 0.01075
Now, we can use this monthly interest rate to calculate the minimum monthly payment:
Minimum monthly payment = 1% x P = 0.01 x $600 = $6
Therefore, the minimum monthly payment is $6.
To find the total cost of the computer over the 2-year period, we need to calculate the total amount paid (A) by making the minimum monthly payment each month:
A = P(1 + rt)
A = $600(1 + 0.01075 x 2 x 12)
A = $600(1 + 0.258)
A = $755.00
Therefore, if you make only the minimum payment each month, the total cost of the computer will be $755.00, which is $155 more than the original cost of the computer ($600).

Answer: The answer is A
Apple products have become a household name in America with 51% of all households owning at least one Apple product (CNN, March 19, 2012). The likelihood of owning an Apple product is 61% for households with kids and 48% for households without kids. Suppose there are 1,200 households in a representative community, of which 820 are with kids and the rest are without kids. Let event A correspond to "Household with kids", and B to "Household owns an Apple product". a. Are the events "household with kids" and "household without kids" mutually exclusive and exhaustive? Yes No b. What is the probability that a household is without kids? (Round your answer to 4 decimal places.) c. What is the probability that a household is with kids and owns an Apple product? (Do not round intermediate calculations. Round your answer to 4 decimal places.) d. What is the probability that a household is without kids and does not own an Apple product? (Do not round intermediate calculations. Round your answer to 4 decimal places.)
Answer:
a. Yes.
b. The probability that a household is without kids:
= 0.3167
c. The probability of a household is with kids and owns an Apple product:
= 61%
d. The probability that a household is without kids and does not own an Apple product:
= 52%
Step-by-step explanation:
a) Data and Calculations:
Probability of a household owning an Apple product = 51%
This implies that the probability of a household not owning an Apple product = 49% (100 - 51)%.
Probability of a household with kids owning an Apple product = 61%
This implies that the probability of a household with kids not owning an Apple product = 39% (100 - 61)%.
Probability of a household without kids owning an Apple product = 48%
This also implies that a household without kids not owning an Apple product = 52% (100 - 48)%.
Sample of households = 1,200
Households with kids = 820
Probability of households with kids = 0.6833 (820/1,200)
Therefore, the probability of households without kids = 0.3167 (380/1200)
b) The events "household with kids" and "household without kids" are mutually exclusive and exhaustive because (a) the two events are separate and do not overlap and (b) the two events are inclusive of all possible options. It is either a household has kids or it does not. In this situation, no middle ground exists.
