What are arithmetic operations?The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.
They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.
As per the given data in the question,
Weight of Rosie when she was born = 7 pounds 11 ounces
Weight of Linda when she was born = 8 pounds 10 ounces
Then, the total weight of these two will be,
= 7 pounds 11 ounces + 8 pounds 10 ounces
= 15 pounds 21 ounces

The weight of an object on earth varies directly as the weight of the same object on the moon. A 300- pound object on earth would weight 48 pounds on the moon. How much would a 65-pound object weight on the moon?
Answer: 10.4 pounds
Step-by-step explanation:
In this case, we have to calculate the constant of proportionality. This can easily be gotten as:
300/48 = 6.25
Therefore, the weight of a 65-pound object weight on the moon will be:
= 65/6.25
= 10.4 pounds
im solving variables -4y + 7 = -10y+37
Answer:
5
Step-by-step explanation:
move the terms
collect like terms
calculate
divide both side
Answer: y = 5
Step-by-step explanation:
(step 1) -4y + 7+ 10y = -10y + 37 + 10y
6y + 7 = 37
(step 2) 6y + 7 - 7= 37 - 7
6y = 30
(step 3) Divided both sides by 6.
6y/6 = 30/6
so the answer is y = 5
Find the values of x.
Answer:
x = 8
Step-by-step explanation:
Using the exterior angle theorem, we know that y = 90 + 6x, and y also equals 180-(5x+2)
So we can write an equality statement
90+6x=180-(5x+2)
Open parenethesis
90+6x=180-5x-2
Same to both sides
6x = 88 - 5x
11x = 88
x=8
Check work:
11x + 2 = 90
88+2 = 90
90 does equal 90.

the value of 2 in 204.75 is how many times the value of 2 in 103.52
Answer:
1000.
Step-by-step explanation:
The Value of the 2 in 204.75, is 200.
The Value of the 2 in 103.52 is 0.02.
So to make the 0.02 become 200, you have to move the decimal point 3 spaces to the right.
Therefore, the 2 in 204.75 is 1000 times greater than the value of the 2 in 103.52.

Given the vectors:
r = (8, 8, -6); v = (3, -8, -3); w = (-4, -2, -6)
Answer:
vw= 22
Step-by-step explanation:
To find the dot product of vw, multiply the corresponding numbers and add them.
v= <3, -8, -3> w= <-4, -2, -6>
vw= (3*-4)+(-8*-2)+(-3*-6)
vw= -12+16+18

Answer: Choice C
x intercept is (4,0)
y intercept is (0,2)
=======================================================
Work Shown:
To find the x intercept, we plug in y = 0 and solve for x
2x+4y = 8
2x+4(0) = 8
2x+0 = 8
2x = 8
x = 8/2
x = 4
We have x = 4 pair up with y = 0. So we have (x,y) = (4,0) as the x intercept.
This is the location where the graph crosses the x axis.
--------------
The y intercept is a similar story, but we use x = 0 to find y.
2x+4y = 8
2(0)+4y = 8
0+4y = 8
4y = 8
y = 8/4
y = 2
The value x = 0 leads to y = 2. This gets us (x,y) = (0,2) as the y intercept.
This is the location where the graph crosses the y axis.

What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
x2 + 34 = 10x
Answer:
So the intermediate step in question is (x - 10)² = 66
Step-by-step explanation:
Let's find out:
x² + 34 = 10x
x² - 10x = -34
x² - 20x + 100 = 66
(x - 10)² = 66
x - 10 = ± √66
x = 10 ± √66

A punch recipe requires 4 cups of crandberry juice to make 5 gallons of punch. Using the same recipe, what is the amount of crandberry juice needed for 1 gallon of punch?
Answer:
4/5 cups
Step-by-step explanation:
Given :
A punch requires ;
4 cups of crandbarry juice = 5 gallons of punch
Thus number of cups of cranberry required to make1 gallon of punch = x
4 cups = 5 gallon
x cups = 1 gallon
Cross multiply
5x = 4
x = 4/5
Thus 4/5 cups of crandberrey is required to make 1 gallon of punch

The outcomes for 2 spins of a spinner with 3 sections that are numbered 1 to 3
====================================================
Explanation:
The three sections {1,2,3} are shown as the three branches for each level. There are 2 levels total. Each of the 2 levels represents a different spin. Each branch of a certain spin would then be followed to generate the outcome.
For instance, if you spin a "2" on the first spin, then you'll follow the middle branch in the upper level. If you spin a "3" on the second spin, then you'll follow the "3" branch on the lower level. Refer to the diagram below.

A circle has radius 26cm and length of it's chord is 48cm.find how far is the chord from the center of the circle?
Answer:
The chord is 10cm from the center of the circle

Here, we want to find the distance of the chord from the center of the circle
A line from the center to the chord will
divide the chord into two parts
each will have a measure of 48/2 = 24 cm
So now we have a right/angled triangle with hypotenuse of 26
To find the height, we use Pythagoras’ theorem which states that the sum of the squares of the other sides equal the square of hypotenuse
h ^2 + 24^2 = 26^2
h^2 = (26-24)(26+24)
h^2 = 100
h = square root of 100, which is 10

2b + 23 = 5b - 112 solved
Answer: b= 45
Step-by-step explanation:
Step 1: Subtract 5b from both sides.
2b+23−5b=5b−112−5b
−3b+23=−112
Step 2: Subtract 23 from both sides.
−3b+23−23=−112−23
−3b=−135
Step 3: Divide both sides by -3.
−3b /-3 = -135/-3
