Step-by-step explanation:
rename 1/2 and 2/3 as fractions with denominators of 6.then add the renamed fractions. write the sum as a mixed number.
Answer:
1 and 1/6
Step-by-step explanation:
To rename a fraction you multiply both numbers by however many times the original denominator goes into the new one.
2 goes into 6 three times.
1 times 3 is 3
and 2 times 3 is 6
so 1/2=3/6
3 goes into 6 twice
2 times 2 is 4
and 2 times 3 is 6
so 2/3=4/6
to add fractions you add the numerators while keeping the denominators the same.
3+4=7 so:
3/6+4/6=7/6
6/6=1
so 7/6 contains 1 whole
once you take that out you have 1/6 left over

A truck is carrying 5 cars weighing a average of 4,500 pounds each. What is the total weight in tons of the cars on the truck?
Answer:
18 tons
Step-by-step explanation:
a) Given: Weight of 1 truck=4500 pounds
Thus, weight of 8 trucks= pounds
We know that 1 ton=2000 pounds
Thus, weight of 8 trucks in tons=
Hence, the total weight in tons the cars on the truck= 18 tons.
b) Given: Dimensions of the room are as
Length=10 yards and width= 168 inches
We know that 1 yard=3 feet and 1 inch=
Thus, length
width=
The difference between length and width=
Hence, the length of the room exceed the width by 16 feet.
what is 91 rounded to the nearest hundred
Answer:
100
Step-by-step explanation:
Answer:
100
Step-by-step explanation:
We have the number 91 and are asked to round to the nearest 100.
When we round to a certain number, we always have to look at the number to the right of the place value being rounded to, if the numbers is 0-4, you will round down, if the number is 5-9, you round up.
Right now we have 094, 0 being the hundreds place, look to the right and see that we have 9. Therefore we round up.

Step-by-step explanation:
Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.
Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.
Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.
Step 3:
Combine like terms: (18 + 24) squared = 30 squared.
Step 4:
Evaluate each side: 1764 not-equals 900.
Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?
The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

The segments in each figure are tangent to the circle at the points shown.
Find each length.
9514 1404 393
Answer:
RS = RT = 2
Step-by-step explanation:
The two tangents from a point are the same length.
RS = RT
y = y^2/2
y^2/2 -y = 0
y(y/2 -1) = 0 . . . . factor out y
Values of y that make these factors zero are ...
y = 0 . . . . . . . . true if points R, S, T are coincident on the circle
y/2 -1 = 0 ⇒ y = 2
Then the segment lengths are ...
RS = RT = 2
2(2x + 3) = -6(x + 9)
Answer:
Your answer is -6.
Step-by-step explanation:
Simplify 2(2x+3) to get 4x+6
Then simplify -6(x+9) to get -6x-54
Now you have 4x+6=-6x-54
Move all of the coefficients to one side:
10x+6=-54
Move all of the constants to the other side:
10x=-60
Divide each side by 10:
10/10x=-60/10
To get your answer of -6.

What’s the area of the figure??
Answer:
b
Step-by-step explanation:
the the area of the square is 36, because 6*6=36
the area of the semicircle on the top is 14.135, because the formula for area is pi R^2, so its 3.14*9 and then/2.
so now we add 36+14.135=50.135 rounded up =50.14

Fabiola's special seasoning mix has three ingredients. The recipe uses 4 parts thyme, 3 parts parsley, and 1 part green onion. If she is making 24 tbsp. of the mix, how many tbsp. of parsley does she need?
3
5
15
9
Answer: 9
Step-by-step explanation: First, you find how many parts are needed. 4+3+1=8
So, we then divide 24 by 8 to find out what one part is. This is 3
As she needs 3 parts of parsley, we multiply 3 by 3 (each part) to get 9 tbsp.
Fabiola's special seasoning mix of 24 tbsp. needs 9 tbsp. of parsley.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Fabiola's special seasoning mix has three ingredients. The recipe uses 4 parts thyme, 3 parts parsley, and 1 part green onion.
Let, 'x' be the ratio multiplier.
Therefore, 4x + 3x + x = 24.
8x = 24.
x = 3.
So, She needs 3×3 = 9 tbsp. of parsley.

The slope of a graph
Please post full question
Answer:
The slope of a line is rise over run. Learn how to calculate the slope of the line in a graph by finding the change in y and the change in x.
The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =riserun Slope = rise run . You can determine the slope of a line from its graph by looking at the rise and run.

Substitute the [-44] value to the first equation
-44=-10x+6
Subtract 6 on both sides
-44-6=-10x+6-6

What is ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b or [tex]\dfrac{a}{b}[/tex]
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
Suppose that we've got a = 6, and b= 4, then:
[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Same thing happens for 3 quantities and more such quantities.
So if its given that Oli, Sam, and Tim's share (total £360) are in the ratio 3:2:1, that means some common factor (lets call it 'x') must be cancelled off as 3+2+1 don't equate to 360.
So, we have:
Oli's share = 3xSam's share = 2xTim's share = 1x = xTheir total evaluates to 360 (in euros).
(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)
Thus, we get:
[tex]3x + 2x + x = 360\\(3+2+1)x = 360\\6x = 360\\\\\text{Dividing both the sides by 6}\\\\\dfrac{6x}{6} = \dfrac{360}{6}\\\\x = 60[/tex]
Thus, we get:
Oli's share = 3x = 3×(60) = £180Sam's share = 2x = 2×(60) = £120Tim's share = 1x = x = £60Thus, the amount that Sam get (the share of Sam) is £120

C
C
Answer:
Answer: B, 6/11
Step-by-step explanation:
Well we know that 3+2+1=6+3=9.
So that means we will add the 2 brown crayons to the denominator.
The denominator before we added 2 to it, it was 9 as a common denominator. If we want to get the common numerator we are going to have to add the top and that will become 9 then you will have to subtract that by 3
6/11 is also the smallest number that you can get.
You can turn the fraction into a decimal and have it that way to make it easier.
When you turn a fraction into a decimal the number is always the same but with comparing numbers it is a lot easier to do than comparing fractions
