Ali drove 585 miles in 9 hours.
At the same rate, how many miles would he drive in 13 hours?
Answer:
845 miles
Step-by-step explanation:
First let us find the speed ( rate ) using the below formula.
[tex]\sf Speed=\frac{Distance \:\:travellled}{Time\:\:Taken}[/tex]
[tex]\sf Speed=\frac{585 \:miles}{9 \:h}[/tex]
[tex]\sf Speed=65\:miles\: per\: hour[/tex]
They also said that, at the same speed he traveled for 13 hours.
So, now we have to find the distance.
For that, you can use the same formula by making the distance as the subject.
Let us find it now.
[tex]\sf Distance \:\:travellled=Speed\:*\:Time\:\:Taken\\\\\sf Distance \:\:travellled=65\:*\:13\\\\\sf Distance \:\:travellled=845 \:miles[/tex]

Answer: D
Step-by-step explanation:
You can either calculate what the rates will give, or try to compare them :
We have 5, 1 (hidden), and 3 as denominators, so 8*3*1 = 24
We'll take that as denominator.
Bank A : [tex]2.35 = \frac{2.35*24}{24}=\frac{56.4}{24}[/tex]
Bank B : [tex]2\frac{1}{3}=\frac{1*2*8}{3*8}=\frac{16}{24}[/tex]
Bank C : [tex]2\frac{5}{8} = \frac{5*2*3}{8*3} =\frac{30}{24}[/tex]
Bank D : [tex]2.61=\frac{2.61*24}{24} = \frac{62.64}{24\\}[/tex]
And now, let's compare the numerators !
[tex]\frac{16}{24} < \frac{30}{24} < \frac{56.4}{24} < \frac{62.64}{24} \\Bank B < Bank C < Bank A < Bank D[/tex]
For each of the graphs below state whether they represent a proportional relationship and how you know. If the graph does represent a proportional relationship find the unit rate.
Make a the subject of the formula:
2a+9b=4
Make w the subject of t=7w+3
Answer:
a = (4 - 9b)/2
w = (t - 3)/7
Step-by-step explanation:
2a + 9b = 4
2a= 4 - 9b
a = (4 - 9b)/2
t = 7w + 3
7w = t - 3
w = (t - 3)/7

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is orange.
A spinner divided into eight equal colored sections, with one orange, two purple, two yellow, and three blue.
Which statement about probability is true?
The probability of landing on orange is greater than the probability of landing on purple.
The probability of landing on yellow is less than the probability of landing on blue.
The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on blue.
Answer:
B. The probability of landing on yellow is less than the probability of landing on blue.
Step-by-step explanation:
because you have a 2/8 chance or 25% chance of landing on yellow whereas you have a 3/8 or 37.5% chance of landing on blue
Answer: B: The probability of landing on yellow is less than the probability of landing on blue.

3. 4 (same)
Answer:
First Sheet: C) 95°
Second Sheet: B) 33°
Third Sheet: B) 4 units
Step-by-step explanation:
First Sheet:
Shape AKGP is the same as VWQX, meaning that the answers will be the same. Angle X is equal to angle P, meaning that the answer is 95°
Second Sheet:
Triangle SRT is equal to PQB. This means that angle Q is equal to angle R which means our answer is 33°
Third Sheet:
Since shape MQRN is equal to PKSD, we basically know the answer. The answer is 4 units because PK is equal to MQ.

14 minus 3z as a phrase.
I'm in 6th grade doing algrebraic experssions.
I have a test tomorrow, so please help me!
Answer:
Step-by-step explanation:
Simplifying
14 + -3z = 0
Solving
14 + -3z = 0
Solving for variable 'z'.
Move all terms containing z to the left, and all other terms to the right.
Add '-14' to each side of the equation.
14 + -14 + -3z = 0 + -14
Combine like terms: 14 + -14 = 0
0 + -3z = 0 + -14
-3z = 0 + -14
Combine like terms: 0 + -14 = -14
-3z = -14
Divide each side by '-3'.
z = 4.666666667
Simplifying
z = 4.666666667
Answer:
14 less than 3 times of a number(z)

Calculate the area of the regular pentagon below:
Answer: 858.55 in
Step-by-step explanation: You calculate the area of the triangle ( 22.3 x 15.4/2), then you multiply the result by 5.
Answer:
858.55
Step-by-step explanation:
Area of triangle = 1/2BH
1/2(22.3*15.4) = 171.71
Because there is five sides on the pentagon we have to multiply the 172.71 by 5 to get the final answer.
171.1(5) = 858.55

Due to the demand of their chicken sandwiches, Popeyes decided to change the price from $2.29 to $2.59. Express this change as a percentage.
A-12% increase
B-12% decrease
C-13% increase
D-88% increase
Answer: C
Step-by-step explanation: You can use the percent error formula if you know it or just do:
value 2 - value 1
x 100 = percent
absolute value of value 1
The correct option C-13% increase. The price of the chicken sandwiches percentage increased by 13%.
Explain the term percentage change?Finding the differences between the two values in such a time series, dividing the difference by the initial value, then multiplying by 100 are used to determine the percentage change here between two values. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.For the stated question;
Original price of the chicken = $2.29
Increased price of the chicken = $2.59.
Let x be the percentage increase:
Thus,
2.29 + x% of 2.29 = 2.59
2.29 + 2.29x / 100 = 2.59
229 + 2.29x = 259
2.29x = 259 - 229 = 30
x = 30 / 2.29 = 13.1
x = 13 % (approx)
Thus, the price of the chicken sandwiches increased by 13%.
