The proportion
75/w = 150/100 can be used to find the whole, w.
Use the language of percent to explain whether
w is less than or greater than 7
Answer:
w is greater than 7
Step-by-step explanation:
Given
[tex]\frac{75}{w} = \frac{150}{100}[/tex]
Required
Determine if w is less than or greater than 7
[tex]\frac{75}{w} = \frac{150}{100}[/tex]
Cross Multiply
[tex]w * 150 = 75 * 100[/tex]
[tex]150w = 7500[/tex]
Solve for w
[tex]w = \frac{7500}{150}[/tex]
[tex]w = 50[/tex]
Convert to percentage
[tex]w = 50 * 100\%[/tex]
[tex]w = 5000\%[/tex]
w is greater than 7 because 50 or 5000% is greater than 7

a. How many copies can it print in 10 minutes?
b. A teacher printed 720 copies. How long did it take to print?
Answer:
a: 1200 b: 6
Step-by-step explanation:
480/4 is 120
120 x 10 is 1200
720/120=6
х+бу =20
x+3y = 14
Solve the simultaneous equations
х+6у =20
x+3y = 14 //-1
-----------------------
х+6у =20
-x-3y = -14
------------------------
3y = 6
y = 2
x + 3(2) = 14
x + 6 = 14
x = 14 - 6
x = 8
An artist is creating tiles to use in a project. Each tile is to be in the shape of a right triangle. The shortest side of a tile is to be 4 inches long. The next shortest side is to be x inches long.
Enter an expression in terms of x that models the longest side of a tile.
Answer:
4 + x
Step-by-step explanation:
Given that :
Shortest side of tile (s) = 4 inches
Next shortest side (a) = x inches long
Longest side of tile (l ) =?
Since it is modeled in the form of a right angjed triangle ; then we can use Pythagoras rule ;
Length of longest side² = sum of the square of the two other sides
l² = 4² + x²
l² = 16 + x²
Take the square root of both sides
l = 4 + x
Hence, length of longest side = 4 + x
Expression in terms of x that models the longest side of a tile is 4 + x
We have
The shortest side of tile = 4 inches
Other shortest side = x inches
As the tiles is to be in the shape of a right triangle.
So, we can use Pythagoras theorem
Length of longest side² = sum of the square of the two other sides
[tex]a^2= 4^2 + x^2\\a^2 = 16 + x^2[/tex]
Taking the square root on both sides, we get
[tex]a = 4 + x[/tex]
Therefore, length of longest side = 4 + x

The rate of change is the slope. You're finding the average between two points, so find the slope between them using the slope formula. It's 20.
Step-by-step explanation:
[tex]m = \frac{y - y1}{x - x1} [/tex]
m is the slope.
plug in the numbers, and you get
[tex] \frac{300 - 200}{6 - 1} = \frac{100}{5} = 20 [/tex]
Liz lives 3 miles from the library.
Brendan lives 3 times as far as Liz.
Andy lives 3 times as far as Brendan.
Eddie lives 3 times as far as Andy.Which exponential expression represents how far Eddie lives from the library?
A.3 the the 5th power miles
B.4 to the 3rd power miles
C.3 to the 4th power miles
D.3 to the 3rd power miles
Answer:
C.
Step-by-step explanation:
3 times 3 =9 and is 3 by the 2nd power. Then that times three is 27 which is 3 to the third power. Now it’s time to find out where Eddie is compared to the library. Then that times 3 is 3 to the fourth power. So that’s how far Eddie is. He is 81 miles away.
Tell whether a triangle can have sides with lengths 3, 4, and 8.
Answer:
Yeah a triangle can have any measurements as long as it makes sense. Your not gonna put the mesurment 8 on the shortest side but the longest, and then the next longest will be 4, and then 3 as the shortest.
Step-by-step explanation:
You'd be lookin for a scalene triangle, Acute triangle, or obtuse triangle, (I'm not so sure about a right triangle, but you might be lookin at that too)

A retail store makes k%
profit on the selling price. What is the least integer value of k
that will enable the store to make a profit of at least 30%
of the cost of the item?
Please answer as soon as possible. i do not understand. me and my friends dont uderstand.
Answer:
10
Step-by-step explanation:
The store wants to make a 20% profit:
Multiply the cost of the toy by 1.20 ( cost plus 20%).
6.25 x 1.20 = $7.50
This means when the toy is sold at 25% off, it needs to be $7.50 to make the 20% profit.
When the item is 25% off, that means it would sell for 75% of the original price.
Now to find what the price needs to be before the 25% off divide the profit price by 75%
7.50 / 0.75 = $10
K = $10

Biologists have found that the number of chirps some types of cricket make per minute depends upon the temperature this relationship can be represented by a linear function when the temperature is 60° Fahrenheit to crickets chirp 92 times per minute if it is 75 Fahrenheit they will chirp 152 times per minute what will the number of chirps be per minute if the temperature is 80 degrees Fahrenheit
Answer: Crickets make 172 chirps/min at 80 degrees Fahrenheit
Step-by-step explanation:
Step 1
Using the point slope formulae for Linear functions , we have that
y - y1 = m(x - x1)
where x and y are two points representing the temperature and chirps /min respectively
And
m= slope
Step 2 : Finding the slope , m
where x1=60
y1=92
x2= 75
y2=152
m= (y2-y1)/ (x2-x1)
= (152- 92)/(75-60)
=60/15 =4
Bringing down the point/slope formula and imputing the known values to find our equation to show the relationship cricket make per minute and the temperature
y - y1 = m(x - x1)
y - 92= 4(x - 60)
y - 92 = 4x -240
y = 4x - 240 + 92
y = 4x - 148
Step 3
To find the number of chirps be per minute (y) if the temperature is 80 degrees Fahrenheit( x)
y = 4(80) - 160
y = 320 - 148
y = 172 chirps/min at 80 degrees Fahrenheit
