Answer:
Step-by-step explanation:
$1500-$250 = $1250
You need to save an additional $1250.
The question did not include a pay rate.
Suppose you earn x dollars an hour.
$1250 × (1 hour)/($x) = (1250/x) hours
You need to work 1250/x hours.

5. David Read's the problem:
Ally bought a T-shirt and a pair of shorts on sale which
reduced prices by 1/4. The total savings on the 2
garments was $10.25. Find the original price for the
pair of shorts.
David says that the original price of the shorts was $41.
Does his answer seem reasonable? Defend your
answer by writing and solving an equation that
represents the situation.
Answer:
No, David's answer does not seem reasonable.
Let x= original purchase amount
25x = $10.25, so solve for x by dividing both sides by .25, and you get x = $41.
If the shirt was $18, the shorts must have been $41-$18 = $23 NOT $41.
Step-by-step explanation:
The probability that a first year student entering a certain private college needs neither a developmental math course nor a developmental English is 70% while 22% require a developmental math course and 25% require a developmental English course. Find the probability that a first year student requires both a development math course and a developmental English course.
Answer:
Probability of both English and Maths = 17%
Step-by-step explanation:
Probability of English or Maths
100 -70 = 30%
Probability of English or Maths =
Probability of English + Probability of Maths + Probability of both English and Maths
30 % = 22% + 25 % + Probability of both English and Maths
Probability of both English and Maths = 47% - 30 %
Probability of both English and Maths = 17%

Solve seven tenths times two fourths
Answer:
with simplify: 1 4/20.
without simplify: 24/20
Step-by-step explanation:
first we have to find the common denominator
can 4 go into 10? no.
can 4 go into 20? yes! it goes into 20, 5 times!
common denominator = 20
_/20 + _/20
what we do to the bottom we do to the top
7 x 2= 14
14/20 + _/20
2 x 5= 10
14/20 + 10/20 = 24/20
now simplify
1 4/20
hope this helped!
I need help with geometry shapes
Answer:
What do you need though...
A basic rundown since I have no clue what you need help with
Parallelograms
(4 sided shapes that always adds up to 360 degrees if you add all the angles inside with opposite sides parallel)
Squares, rectangles (most common)
Triangles
3 sided figures with all the interior angles being added up equals to 180 degrees. The 3 sides of a triangle can be found with a^2+b^2=c^2.
The properties are 2 legs and 1 hypotenuse. To determine if its a triangle, if the 2 legs added up (two of the shortest sides) they must be greater then the hypotnuse (greatest side).
THese are the two of the most common shapes if you need an huything else just lemme know in the comments.
If you can answer these simple questions im giving brainly :)
Answer:
65 3 46
Step-by-step explanation:
Answer:
a² + 1 = 65
18/2a = 3
6(d + 8) - 10d = 46
Step-by-step explanation:
a² + 1 when a = 8
first, plug in 8 for a.
a² + 1 ⇒ 8² + 1begin simplifying by finding 8², which is just 8 · 8.
8² + 1 ⇒ 64 + 1finish simplifying by adding 64 + 1.
64 + 1 = 65therefore, when a = 8, a² + 1 = 65.
18/2a when a = 3
first, plug in 3 for a.
18/2a ⇒ 18/2(3)begin simplifying by multiplying 2 · 3.
18/2(3) ⇒ 18/6finish simplifying by dividing 18 ÷ 6.
18/6 = 3therefore, when a = 3, 18/2a = 3.
6(d + 8) - 10d when d = 1/2
(i'm going to convert 1/2 to 0.5 because i prefer working with decimals rather than fractions)
so... 6(d + 8) - 10d when d = 0.5
first, plug in 0.5 for d.
6(d + 8) - 10d ⇒ 6(0.5 + 8) - 10(0.5)begin simplifying by distributing 6 to 0.5 and 8, which is just 6 · 0.5 and 6 · 8.
6(0.5) = 36(8) = 48after distributing, your expression is 3 + 48 - 10(0.5).
continue simplifying by multiplying -10 · 0.5.
3 + 48 - 10(0.5) ⇒ 3 + 48 - 5add 3 + 48.
3 + 48 - 5 ⇒ 51 - 5finally, finish simplifying by subtracting 5 from 51.
51 - 5 = 46therefore when d = 1/2 or 0.5, 6(d + 8) - 10d = 46.

4x + y = 14
Yes
No

Next
Page 1 of 3
Answer:
x = 5 and y = -6
Step-by-step explanation:
The given equations are :
6x + 3y = 12 ...(1)
4x + y = 14 ...(2)
Multiply equation (2) by 3.
12x + 3y = 42 ...(3)
Subtract equation (1) from (3).
12x + 3y-(6x + 3y) = 42-12
12x+3y-6x-3y = 30
6x = 30
x = 5
Put th value of x in equation (2).
4(5) + y = 14
20 +y = 14
y = -6
So, the solution of the equations are x = 5 and y = -6.

Sam is 4 years younger than Amy. Five years ago he was half her age. How old are they now?
Answer
Answer:
Let's say that x is sam's age and y is Amy's age
x=y-4
and five years ago:
x-5=(y-5)/2
y-4-5=(y-5)/2
2y-18=y-5
y=13
x=9
then:
sam's age is 9 and Amy's age is 13
Answer:
Sam: 9, Amy: 13
Step-by-step explanation:
So five years ago, lets say Sam was 4, and Amy was 8. That would be half Amy's age. If we add on 5 to Sams age, as it says, Amy would then be 13, and Sam would be 9. This is also four years apart. Thus, the answers are Sam: 9 and Amy: 13

Question 3
Circle A has area of 500 in^2. The diameter of Circle B is three times the diameter of circle A. Estimate the area of circle B.
Answer:
750^2
Step-by-step explanation:
backtrack and find the diameter of circle A. A=πr, which means the diamater is about 159 1/11. three times the diameter will give 477 3/11, so the radius is 238 7/11. multiply it to 22/7 (π) then you get 750^2.

Answer:
6.3 in.^2
Step-by-step explanation:
The diameter of the circle is 4 in., so the radius of the circle is 2 in.
[tex] A_{sector} = \dfrac{n}{360^\circ} \pi r^2 [/tex]
The two central angles have a total measure of 60 deg + 110 deg = 170 deg.
The central angle of the shaded sector is 360 deg - 170 deg = 190 deg.
We will use n = 190 deg in the area formula.
[tex] A_{sector} = \dfrac{190^\circ}{360^\circ} \pi (2~in.)^2 [/tex]
[tex] A_{sector} = 6.3~in.^2 [/tex]

Now look at the 5-year performance of Amazon. What do you think explains the general upward trend of the stock price?
Answer:
expansion
Step-by-step explanation:
I believe that the biggest reason for the general upward trend in the stock price is expansion. Amazon has expanded their company immensely over the last 5 years. They have also expanded into different markets such as drones, gaming, cloud streaming, video streaming, etc. All of these expansions and acquisitions have been incredibly profitable for Amazon and therefore reflect on the stock price. This also gives investors faith that the future of the company will continue growing which causes them to buy more stocks and therefore increase the price.
