Step-by-step explanation:
[tex]26 = x + y \\ where \: x \: is \: the \: pack \: of \: pens \: and \: y \: is \: for \: the \: binders \\ but \: x = one \: pack \: of \: pens \\ = 1 \times 4.15 \\ y = 5 \times number \: of \: binders \\ substituting \\ 26 = 1(4.15) + 5x \\ 26 - 4.15 = 5x \\ 21.85 = 5x \\ x = 4.37[/tex]
Jasmine has only $26 to buy her materials, and we found that the highest number of binders she could buy is at 4.37.
The variable is the second x which is the number of binders since she could change the amount of binder she wants to buy. Comparing to the one pack of pens, Jasmine has already decided that she will only buy one not two, not three, etc. Therefore, the pack of pens is not a variable as she cannot change the amount of pack of pens she can buy.
Answer:
she could buy 4 binders and 1 pack of pens and she have 85cents left

find two consecutive even integers whose sum is 54
Answer:
1st integer = x
2nd integer = x + 2
x + x + 2 = 54
2x + 2 = 54
2x = 52
x = 26
The 1st integer is 26.
The 2nd integer is 28.
Let's add these numbers.
26 + 28 = 54
54 = 54
This checks out.
let the nos be x and x+2
x + (x+2) = 54
2x + 2 = 54
2x = 52
x = 26
x+2 = 28
therefore the nos are 26 and 28
hope it helps you
Your Friend, Ella.
Step-by-step explanation:
Answer:
26+28
Step-by-step explanation:
54 / 2 = 27
27 and 27 are odd, so go up 1, and down 1
26 and 28 are both even.

Annabeth has $29.00 to spend at the sporting goods store. She buys a T-shirt that costs $15.32. She also wants to buy a soccer ball for $12.87, a baseball cap for $8.39, a set of shin guards for $14.98, or a water bottle for $5.93. Use the equation $15.32 + c = $29.00, where c is the item's cost, to find the most expensive item Annabeth can buy.
Answer:
The most expensive she can buy is the soccerball
Step-by-step explanation:
Given
[tex]Total =\$29.00[/tex]
[tex]T\ Shirt = \$15.32[/tex]
[tex]Soccer\ Ball= \$12.87[/tex]
[tex]Baseball\ Cap = \$8.39[/tex]
[tex]Shin\ Guards = \$14.98[/tex]
[tex]Water\ Bottle = \$5.93[/tex]
Required
Using [tex]\$15.32 + c = \$29.00[/tex], what is the most expensive she can buy?
[tex]\$15.32 + c = \$29.00[/tex]
Subtract $15.32 from both sides
[tex]\$15.32 - \$15.32 + c = \$29.00 - \$15.32[/tex]
[tex]\$15.32 - \$15.32 + c = \$13.68[/tex]
[tex]c = \$13.68[/tex]
This means that she can not afford items that cost more than $13.68
i.e. the shin guards which costs $14.98
The items she can afford and their prices are:
[tex]Soccer\ Ball= \$12.87[/tex]
[tex]Baseball\ Cap = \$8.39[/tex]
[tex]Water\ Bottle = \$5.93[/tex]
The most expensive of them all is:
[tex]Soccer\ Ball= \$12.87[/tex]
A container of candy is shaped like a
cylinder and has a volume of 125.6 cubic
centimeters. If the height of the container is 10
centimeters, what is the radius of the
container?
Answer:
The radius of the container is 2 centimeter
Step-by-step explanation:
Given that a container of candy is shaped like a cylinder
Given that volume = 125.6 cubic centimeters
Height of conatiner = 10 centimeter
To find: radius of the container
We can use volume of cylinder formula and obatin the radius value
The volume of cylinder is given as:
Where "r" is the radius of cylinder
"h" is the height of cylinder and is constant has value 3.14
Substituting the values in formula, we get
Taking square root on both sides,
Thus the radius of the container is 2 centimeter

A map using a scale inch of 1 to 5 miles shows a section of land with an area of 3.2 in.² what is the actual area of the section of land
Answer:
The actual area of land is 80 mi² .
Step-by-step explanation:
Given that we have to find the actual area so first we have to square the ratio(scale factor) :
1 in : 5 mi
(1 in)² : (5 mi)²
1 in² : 25 mi²
Next, the actual area will be :
1 in² = 25 mi²
(1 × 3.2) in² = (25 × 3.2) mi²
3.2 in² = 80 mi²
The actual area of the section of land if A map using a scale inch of 1 to 5 miles shows a section of land with an area of 3.2 in.² is 80 miles².
What is an area?An area is a unit of measurement used to describe the size of a region on a planar or curved surface. While a plane region or area refers to the area of a shape or planar lamina, a surface region or plane area refers to the area of an open surface or the boundary of a three-dimensional object.
Given:
A map using a scale inch of 1 to 5 miles, land with an area of 3.2 in.²
Calculate the scale factor as shown below,
1 inch: 5 miles
(1 inch)² : (5 miles)²
1 inches² : 25 miles²
Calculate the actual area as shown below,
Actual area = 25 × 3.2
Actual area = 80 miles²

At the start of the year a summer holiday to Spain cost £650. It increased by 11% in
March and by a further 8% in May. Calculate the final cost of the holiday after the
two increases. Give your answer to the nearest £.
Answer:
Final cost = £779
Step-by-step explanation:
It is given that:
Cost of summer holiday = £650
Amount increased by 11%
Increased cost = 11% of 650
Increased cost = [tex]\frac{11}{100}*650[/tex]
Increased cost = 0.11 * 650 = £71.50
Amount after increment = 650 + 71.50 = £721.50
Further increase = 8%
Amount = 0.08 * 721.50 = £57.72
Final cost = 721.50 + 57.72 = £779.22
Thus,
Final cost = £779

Mr. Kory owns a corn dog stand. In August, he lowered the price of his corn dogs by 10%. As a result, he sold 25% more corn dogs in August than he sold in July. If he sold 1,500 corn dogs in July at a price of $1 each, which equation could be used to determine s, the total amount of money from corn dog sales in August?
F s = 0.10 x 1 x 0.25 x 1500
G s = 1.10[1500 + 0.25(1500)]
H s = 0.9[1500 + 0.25(1500)]
J s = 0.9(1500 x 0.25)
Answer:
H s = 0.9[1500 + 0.25(1500)]Step-by-step explanation:
Cost = $1Sold in August = 1500Discount = 10%Increase in sale = 25%The equation to reflect the change:
(1 - 10%)*(1500 + 25%) =0.9*1500*1.25Correct one is H s
Answer:
H s = 0.9[1500 + 0.25(1500)]

Half of Robert's piece of wire is equal to ⅔ of Maria's wire. The total length of their wires is 12 feet. How much longer is Robert's wire than Maria's?
Answer:
Robert's piece of wire is 5 feet long
and Maria's piece of wires is 7 feet long
Step-by-step explanation:
Suppose x and y are Robert's and Maria's piece of wires respectively.
We can write following equation using this statement "Half of Robert's piece of wire is equal to ⅔ of Maria's wire".
[tex]\frac{1}{2} x = \frac{2}{3} y[/tex] --------------(1)
The total length of their wires is 12 feet.
[tex]x+y=12[/tex] ------------(2)
=> [tex]x=12-y[/tex]
Substitute x=12-y in equation (1)
[tex]\frac {1}{2} (12-y) = \frac{2}{3} y[/tex]
[tex]6-\frac{1}{2} y = \frac {2}{3} y[/tex]
[tex]6 = \frac {2} {3} y + \frac {1} {2} y[/tex]
[tex]y=7[/tex]
Put y=7 in equation (2)
[tex]x+7 = 12 \\x =5[/tex]

A jar contains nickels and dimes. There are 20 coins in the jar, and the total value of
the coins is $1.40. How many nickels and how many dimes are in the jar.
Write the system of equations used to solve this problem. Define the variables.
(Hurry)
Answer:
Step-by-step explanation:
n and d are the number of nickels and dimes, respectively.
"there are 20 coins"
n+d = 20
d = 20-n
"total value is $1.40"
0.05n + 0.10d = 1.40
0.05n + 0.10(20-n) = 1.40
-0.05n + 2 = 1.40
0.05n = 0.6
n = 12
d = 20-m = 8

Find the Quadratic function y=a(x-h)^2 who's graph passes through the given points (4,-2) and (2,0)
Given:
The graph passes through the given points (4,-2) and (2,0).
To find:
The quadratic function [tex]y=a(x-h)^2[/tex].
Solution:
We have, quadratic function
[tex]y=a(x-h)^2[/tex] ...(i)
The graph passes through the given points (4,-2) and (2,0). It means the equation must be true for these points.
Putting x=4 and y=-2 in (i), we get
[tex]-2=a(4-h)^2[/tex] ...(ii)
Putting x=2 and y=0 in (i), we get
[tex]0=a(2-h)^2[/tex] ...(iii)
Divide (iii) by (ii).
[tex]\dfrac{0}{-2}=\dfrac{a(2-h)^2}{a(4-h)^2}[/tex]
[tex]0=\dfrac{(2-h)^2}{(4-h)^2}[/tex]
[tex]0=(2-h)^2[/tex]
[tex]0=2-h[/tex]
[tex]h=2[/tex]
Putting h=2 in (ii), we get
[tex]-2=a(4-2)^2[/tex]
[tex]-2=a(2)^2[/tex]
[tex]-2=a(4)[/tex]
Divide both sides by 4.
[tex]\dfrac{-2}{4}=a[/tex]
[tex]\dfrac{-1}{2}=a[/tex]
Putting [tex]a=-\dfrac{1}{2}[/tex] and h=2 in (i), we get
[tex]y=-\dfrac{1}{2}(x-2)^2[/tex]
Therefore, the required quadratic function is [tex]y=-\dfrac{1}{2}(x-2)^2[/tex].
