michael is one-third of keanus age if the sum of their ages is 52 how old is michael
Answer:
Michael age is 13 and keanus age is 39
Step-by-step explanation:
Michael is 1/3 of keanus age
so Michael is 1 and keanus is 3 so if u add them all up it's 4 so 52 divide by 4 it's 13 so Michael is 13 and if you times three it will be 39, and if u add their age together it adds up to 52 so it's 13

Margie has 15 feet of ribbon. It takes 7/8 of a foot of ribbon to make a bow for a bouquet. How many bows can Margie make with her ribbon?
Margie can make 13 bows with her ribbon.
In the US, a foot is used to measure length or distance. "Feet" is the plural form of the single unit of measurement known as "foot." Foot or feet are denoted by the letter ft.
Margie has 15 feet of ribbon.
To make a bow for a bouquet, it takes 7/8 of a foot of ribbon for a bouquet.
1 bow = 7/8 × 1 foot
Therefore, the number of bows Margie can make with the ribbon will be:
Number of bows = 7/8 × 15 feet
Number of bows = 13.125 ≈ 13
Hence, Margie can make 13 bows with her ribbon.

A carpenter has a 15 foot ladder. For safety, the bottom of his ladder must be placed 5 feet from the wall. In order to complete his work, the ladder must reach 14.5 feet up the wall. Under these conditions, can the carpenter complete his work? Rounded to the nearest tenth, how far up the wall does the ladder reach?
The carpenter will not be able to complete his work because the ladder reach 14.1 ft up the wall.
In this question, we have been given a carpenter has a 15 foot ladder. For safety, the bottom of his ladder must be placed 5 feet from the wall.
Consider the following diagram.
In right triangle ABC, AC represents the length of the ladder, CB is the distance between wall and the bottom of the ladder.
Using Pythagoras theorem,
AC² = AB² + BC²
15² = 5² + AB²
225 - 25 = AB²
AB = √200
AB = 14.1 ft ............(1)
We have been given that in order to complete his work, the ladder must reach 14.5 feet up the wall.
From (1), we can see that the ladder will reach 14.1 ft up the wall.
This means, under these conditions, the carpenter will not be able to complete his work.

Find the equation of a line that passes through the point (1,-3) and has a gradient of 3.
Leave your answer in the form
a
x
+
b
y
=
c
Where
a
,
b
and
c
are integers.
Answer:
3x+1y=0
Step-by-step explanation:
the equation of a straight line on a graph is y= mx+c
where m is the gradient and c is the y intercept.
we know that the line passes through (1,-3) and has a gradient of 3, therefore we can substitute these values into the equation.
-3 = 3*1 +c
3 = 3+c
c = 3-3 = 0
therefore the equation of this line is y = 3x+0
now we have to write this in the form ax+by=c
3x+1y=0
Does anyone know how to do this? Or tell me how you do these questions?
The equation of line in slope intercept form can be written as y = mx + c where m is the slope of line and c is the y intercept.
We are given three equations namely y = 2x -2, y = -x + 1 and y = x - 4 and we need to determine the description of equation, slope and y intercept. The equation y = 2x - 2 is the equation of straight line. If we compare this equation with the slope intercept form of line then, m = 2 and c = -2. Thus, slope is 2 and y intercept is -2. The equation y = -x +1 is the equation of straight line. If we compare this equation with the slope intercept form of line then, m = -1 and c = 1. Thus, slope is -1 and y intercept is 1. This equation y = x - 4is the equation of straight line. If we compare this equation with the slope intercept form of line then, m = 1 and c = -4. Thus, slope is 1 and y intercept is -4. The graphs of the equation are attached below.

How many miles can Paul travel on the $110?
Answer:
C=38.48+0.5x
about 143 miles
Step-by-step explanation:
$38.48 base cost plus $.50 per mile, so after x miles, it would be 0.5x
so C=38.48+0.5x
to find how many miles Paul can travel
we set 110=38.48+0.5x
then solve
x=143.04
so Paul can travel about 143 miles

What is share?Real estate investment trusts, limited partnerships, and mutual funds all employ shares as a sort of unit. A share is an immovable unit of capital that symbolizes the ownership connection between the company and the shareholder. The denominated value of a share is its face value, which could not be the same as the share's market value.
The capital of a firm consists of the whole face value of its issued shares.
Total amount of chocolate purchased = 10 kg
Amount of chocolate each friend want =1/7 kg
So, number of people who can get share = 10 / (1/7)
= (10×7)/1

f(x) =square root of x -6. find the inverse of f(x) and it’s domain
The equation of the inverse function is f'1(x) = x^2 + 6 and the domain is all set of real numbers
How to determine the inverse functions?The function f(x) is given as
f(x) = √x -6
Rewrite as
y = √x -6
Switch/swap the positions of x and y in the above equation
The equation becomes
x = √y -6
Make y the subject of the formula in the above equation
The equation becomes
y - 6 = x^2
Add 6 to both sides
y = x^2 + 6
Rewrite as an inverse function
f'1(x) = x^2 + 6
Hence, the inverse function is f'1(x) = x^2 + 6

1) Mrs. Martins deposits $2,650 into a savings account. The account earns 6%
interest per year, and the interest is not compounded. How much amount will
be in the account after 9 years?
The amount in the savings account of Mrs. Martins after 9 years will be $4081.
According to the question,
We have the following details:
The amount deposited in the savings account or the principal amount = $2,650
Interest per year = 6%
Time = 9 years
(It is given that the interest is not compounded.)
Now, using the formula of simple interest, we will first find the total interest after 9 years,
Simple Interest (S.I.) = (Principal * Rate * Time)/100
S.I. = (2650*6*9)/100
S.I. = (2650*54)/100
S.I. = 143100/100
S..I. = $ 1,431
Now, the total amount in the savings account would be the sum of the principal amount and the total interest.
So, we have:
Total amount = Principal + S.I.
Total amount = $ (2,650+1,431)
Total amount = $ 4,081
Hence, the total amount in Mrs. Martins's savings account is $ 4,081.
