Marshall is buying a new phone that costs $150. It is on sale for 25% off plus there is a 6% sales tax. How much will Marshall pay for the phone after the discount and sales tax?
Answers
Answer:

costs of phone = $150
discount= 25%
tax= 6%
amount of discount

if it costs 3.99 for 24 ounces how much woud it cost for 1
Answers
Answer:0.16625
Step-by-step explanation:
Answer:
~6.02
Step-by-step explanation:
It's a ratio
3.99 : 24
1 : 6.015037593984962
or....
1 : 6.02
I got my answer as "6.015037593984962" because from 3.99 to 1, you need to divide by 3.99 (any number divided by itself gives you 1), and so when you do something to one side, you do it to the other. So then I did 24 divided by 3.99 and i got "6.015037593984962". Since that number is big, I suggested rounding it up to the nearest hundredth, and that is at the number "1". Since the next number after "1" is "5" I rounded up "1" to "2" because....4 or less, let it rest, 5 or more, let it sore. And since it's the number 5, I rounded up the 1 to 2. And so I converted "6.015037593984962" to "6.02".

Step-by-step explanation:
distributive property: multiply both terms in the parentheses by the term outside the parentheses (3)
3 times x = 3x
3 times -2= -6
3x-6=15
move -6 to other side by adding 6+15
3x=21
divide 21 by 3
x=7
Answer:
x=7
Step-by-step explanation:
Evalute to 3x-6=15, then add 6 to both sides. Then, divide 3 by both sides to get x by itself getting you a answer which becomes, x=7.

A unicycle tire can travel 7.85 ft. in on revolution. What is the area of the unicycle tire? Round answer to the nearest tenth.
Answers
Answer:
The answer would be 0.06
Step-by-step explanation:
Answer:
4.9ft^2
Step-by-step explanation:
7.85 ft is the circumference of the tire (circle), so [tex]\pi[/tex]d = 7.85.
7.85/[tex]\pi\\[/tex] = 2.5, the diameter is 2.5, so the radius is 1.25.
[tex]\pi[/tex]r^2 is the formula for the area, so [tex]\pi[/tex]*1.25^2 = 1.5625[tex]\pi[/tex], which is 4.906, which rounded to the tenth is 4.9.

needing help please...
Answers
Given:
Perimeter of a parallelogram = 64 cm
Length = 3 times larger than the width
To find:
The length of the parallelogram.
Solution:
We know that, the perimeter of the parallelogram is:
[tex]P=2(l+w)[/tex]
Where, l is length and w is width of the parallelogram.
We have, l = 3w and P=64.
So,
[tex]64=2(3w+w)[/tex]
[tex]64=2(4w)[/tex]
[tex]64=8w[/tex]
Divide both sides by 8.
[tex]8=w[/tex]
Now,
[tex]l=3w[/tex]
[tex]l=3(8)[/tex]
[tex]l=24[/tex]
Therefore, the length of the parallelogram is 24 cm.
A number cube is rolled twice. What is the probability of getting a 6 on the first roll,
then a number less than 5 on the second roll?
A. 5/36
B. 1/9
C. 2/3
D. 1/36
Answers
Answer:
b. 1/9
Step-by-step explanation:
1. 1/6 is the probability of rolling 6
2. 4/6 is the probability of rolling less than 5
3. Multiply them: [tex]\frac{1}{6} x\frac{2}{3}[/tex]
4. Answer: 1/9
The probability of getting a 6 on the first roll, then a number less than 5 on the second roll should be option b.
Calculation of the probability:since
1/6 should be considered as the probability of rolling 6
And, 4/6 is the probability of rolling less than 5
So [tex]= 1\div 6 \times 2\div 3[/tex]
= 1/9
Hence, the option b is correct.

Together they can do that work in 5 hours
or in 1 hour [tex]\frac{1}{5}[/tex] part of work is done
