The hourly rate for Kira by mowing her neighbor's lawn is $7/hour.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
Kira earned $7 mowing her neighbor's lawn for an hour.
So,
$7 ⇒ 1 hour
So $7/hour will be the hourly rate.
Hence "The hourly rate for Kira by mowing her neighbor's lawn is $7/hour".

Step-by-step explanation:
Which weighs more: a watermelon that weighs 7.5 kilograms or a baby that weighs 12
pounds? Explain your reasoning. Note: 1 pound is about 0.45 kilograms.
Answer:
A 12 pound baby is equivalent to 5.4kg, while a watermelon weighs 7.5kg, which is obviously larger than 5.4, so the watermelon weights more.
Step-by-step explanation:
To start off, we should convert the numbers in the same units. The question has told us that 1 pound is around 0.45kg. So let's do 12 * 0.45 which gives us 5.4kg. We already know that a watermelon weighs 7.5 kilograms, so from this we know that the watermelon weighs more.

A trapezoidal window is 8 feet tall and has base lengths of 1 foot and 7 feet. What is the area of the window? The area of the window is _____ square feet.
Can you help me do it.
Answer: 32 ft²
Step-by-step explanation:
The area of a trapezoid is calculable using the formula:
= (a + b)/ 2 * height
Where a and b are the base lengths.
= (1 + 7) / 2 * 8
= 8/2 * 8
= 4 * 8
= 32 ft²

If x is measured in yards and your boss wants a 2" thickness of mulch, how many cubic yards should he order?
Answer:
1000. Then 1000 divided by 324 = 3.08 cubic yards.
Step-by-step explanation:
Answer:
0.8585 cubic yards
Step-by-step explanation:
inches-->yeards 2/36 in
15.453*2/36 = 0.8585 (tried volume formula)
I figured if the derivative represented the area then x^2*x = x^3 so that would represent the volume of mulch needed.
Currently a product has a gear ratio of 17:5, driver:driven. If the company wants to change the product to have the same gear ratio but a driver with 34 teeth, how many teeth must go on the the driven gear?
Answer:
10 teeth must go on the driven gear
Step-by-step explanation:
Let the number of teeth be x
In order for the new product to maintain the same ratio as the old the ratio must remain the same. This means that
17:5 = 34:x
[tex]\frac{17}{5} = \frac{34}{x}\\Now\ let\ us\ cross-multiply\\17 \times x = 5 \times 34\\17x = 170\\dividing\ both\ sides\ by\ 17 \\x = \frac{170}{17} \\x = 10[/tex]
∴ 10 teeth must go on the driven gear
hence ratio = 34:10
At the fair concession stand, a drink costs $1.50, and a hot dog costs $2.75. If Jacob has $18 to spend on food, how many of each item can he buy?
3 drinks and 7 hot dogs
3 drinks and 5 hot dogs
2 drinks and 7 hot dogs
2 drinks and 5 hot dogs
Answer:
Answer is D (2 drinks and 5 hotdog's)
Step-by-step explanation: 1st answer is over as it is $19.25 for only the hotdogs. 2nd is $18.50 which is a little over. 3rd one is $22.25. And the forth one is $16.75 which is perfect because he cant buy anything else with the remainder of his money.
You can use trial and error for 3 drinks and 2 drinks and can see how many hot dogs are available for Jacob to buy in $18 budget.
Jacob, with $18 dollars for food, under given conditions, can buy:
Option D: 2 drinks and 5 hot dogs.
How to decide what amount of drinks and hot dogs are obtainable in given $18 budget?This can be modeled by mathematical expression with use of variables, and inequality.
Suppose that you can by [tex]x[/tex] drinks and [tex]y[/tex] hot dogs, then their amount should not exceed $18 and they should try to use that $18 as much as they can.
Since 1 drink costs $1.5 and 1 hot dog costs $2.75, thus,
[tex]1.5x + 2.75y \leq18[/tex]
Using trial and error for 2 and 3 drinks (we could've done fro 5 or 7 hot dogs too)For 2 drinks:
Since x = amount of drinks = 2, thus from the obtained inequality, we have:
[tex]1.5x + 2.75y \leq 18\\1.5 \times 2 + 2.75y \leq 18\\2.75y \leq 18 - 3\\y \leq \dfrac{15}{2.75}\\\\y \leq 5.555...\\y = 5[/tex]
We took y = 5 since it is closest integer less than 5.55... since we cannot buy drink or hot dog in decimal points generally and cannot spend more than $18
Thus, if Jacob buys 2 drinks, then he can by 5 hot dogs at max.
For 3 drinks:
Since drinks' amount increased, then hot dogs amount will have to decrease to keep them together under $18. And since in 2 drinks Jacob could by 5 hot dogs, thus, now he will have to buy less than 5 hot dogs, which are not given in options.
Thus,
Jacob, with $18 dollars for food, under given conditions, can buy:
Option D: 2 drinks and 5 hot dogs.

EASY BRAINLY/ POINTS!! PLEASE HELP
Answer: The answer would be x = 19/3, 5/3
Step-by-step explanation:
Since we are finding the x intercepts, we must set the equation to equate 0. So:
0 = 3 |x-4| - 7
Then, we want to simplify the right side so it is just the absolute value, so lets start by adding 7 to both sides.
0 = 3 |x-4| - 7
+7 +7
7= 3 |x-4|
Now we divide both sides by 3.
7= 3 |x-4|
3 3
7/3 = |x-4|
Now, due to the properties of absolute value, we must solve this twice, since absolute value always leads to a positive value, we want to set up one equation where 7/3 is positive and one where it is negative.
7/3 = x-4 -7/3 = x-4
add 4 to both sides
7/3 = x-4 -7/3 = x-4
+4 +4 +4 +4
Then, you get your two x values
x= 6.333... or 19/3 AND x = 1.66666 or 5/3

Answer:
The slope is 25 and the y-intercept is 100
Step-by-step explanation:
With linear equations (y = mx + b), m is always the slope, which, in this case, is 25. It could also be written as [tex]\frac{25}{1}[/tex], although it's not necessary here
B is always the y-intercept, which is 100 here

Finite Math Examples. Popular Problems · Finite Math. Find the Distance Between Two Points (7,2) , (-1,4).
Answer:
The distance is Sqrt(130) or in decimal form, 11.01...
Step-by-step explanation:
The distance formula states that you need to do sqrt((a-x)^2+(b-y)^2)). In this scenario (x,y)(a,b)= (1,7)(-2,-4) So we just fill in that formula. (-2-1)=-3^2=9; (-4-7)=11^2=121; 121+9=130. The distance is therefore Sqrt(130) or in decimal form, 11.01...
