Caleb is at the grocery store and plans on buying cans of soup and frozen dinners, but
is concerned about their sodium content. Each can of soup has 500 mg of sodium and
each frozen dinner has 650 mg of sodium. How many milligrams of sodium are there
in 3 cans of soup and 4 frozen dinners? How many milligrams of sodium are there in
c cans of soup and f frozen dinners?
Answer:
Look at the step by step
Step-by-step explanation:
3 cans of soup: 1500 mg of sodium
4 frozen dinners: 2600 mg of sodium
together they are 4100 mg of sodium
How many milligrams of sodium are there in c cans of soup: [tex]500c[/tex]
How many milligrams of sodium are there in f frozen dinners: [tex]650f[/tex]
There is 4100 mg of sodium together in 3 cans and 4 frozen dinner. 500c milligrams of sodium is there in c cans of soup and 650f milligrams of sodium is there in f frozen dinners
What is Expression?An expression is combination of variables, numbers and operators.
Each can of soup has 500 mg of sodium and
each frozen dinner has 650 mg of sodium
1 can =500mg
frozen dinner = 650 mg
3 cans=3(500)=1500 mg
4 frozen dinner = 4(650) mg=2600 mg
Together there is 1500+2600= 4100 mg of sodium
500c milligrams of sodium is there in c cans of soup
650f milligrams of sodium is there in f frozen dinners
Hence, there is 4100 mg of sodium together in 3 cans and 4 frozen dinner. 500c milligrams of sodium is there in c cans of soup and 650f milligrams of sodium is there in f frozen dinners

I think it may be 31%
Answer:
50%
Step-by-step explanation:
There are a total of 640 fries.
40% of them are crispy. Therefore, let C be the amount of crispy fries:
[tex]C=0.4(640)=256[/tex]
Thus, the amount of soggy fries S would be:
[tex]S=640-256=384[/tex]
The total of the crispy fries and the soggy fries is the sum of the fries not on the floor and on the floor. Let F denote on the floor and let NF denote not on the floor. Thus:
[tex]C=C_F+C_{NF}[/tex]
C is 256:
[tex]256=C_F+C_{NF}[/tex]
Same thing for soggy fries S:
[tex]S=S_F+S_{NF}\\[/tex]
S is 384, thus:
[tex]384=S_F+S_{NF}[/tex]
We are told that 80% of the soggy fries are on the floor. Therefore:
[tex]S_F=0.8(384)=307.2[/tex]
This means that the amount of soggy fries not on the floor is:
[tex]S_{NF}=S-S_F\\S_{NF}=384-307.2=76.8[/tex]
We are given that 32% of all the fries are not on the floor. Therefore:
[tex]NF=0.32(640)=204.8[/tex]
The total amount of fries not on the floor is the sum of the amount of crispy fries and soggy fries not on the floor. Thus:
[tex]NF=C_{NF}+S_{NF}[/tex]
We know that NF is 204.8 and that S(NF) is 76.8. Substitute:
[tex]204.8=C_{NF}+76.8[/tex]
Subtract 76.8 from both sides:
[tex]C_{NF}=128[/tex]
This means that out of the 256 crispy fries, only 128 of them are not on the floor.
This means that the amount on the floor is 256-128, or also 128.
Thus, the percentage of crispy fries on the floor is:
[tex]=\frac{128}{256}=50%[/tex]
Our answer is 50%
Sara is trying to build the number 0.140 with base ten blocks. She has thousandths blocks, hundredths blocks, and NO tenths blocks. How can she represent 0.140?
Answer:
0.140 is represented using 40 thousandth blocks and 100 hundredth blocks
Step-by-step explanation:
Base 10 blocks are blocks in set of four which can be used together to represent any number. Also base 10 blocks can be used to perform mathematical computations like addition, subtraction, addition, division, area and many more.
We have to represent 0.140 using hundredths and thousandths blocks.
0.140 = 140 × 10⁻³ = 40 × 10⁻³ + 100 × 10⁻²
10⁻³ represents the thousandth block and 10⁻² for the hundredth. Hence:
0.140 = 140 × 10⁻³ = 40 × 10⁻³ + 100 × 10⁻² = 40 thousandth + 100 hundredth
0.140 is represented using 40 thousandth blocks and 100 hundredth blocks
Find the midpoint of the segment AB with coordinates A(4, 3/4) and B(-2, 1/4).
answer :
( 1, 1 / 2 )
explanation :
Midpoint formula :
(x^1, y^1) , (x^2, y^2)
M = ( x^1 + x^2 / 2 ), ( y^1 + y^2 / 2 ).
(x^1, y^1) = (4, 3/4), (x^2, y^2) = (-2, 1/4).
= ( -2 + 4 / 2, 1/4 + 3/4 / 2 )
= ( 1, 1 / 2 )

A piece of chocolate is 4/5 inch long. Meg lays 4 chocolate pieces end to end in a row. How many inches long is the row of chocolates ( please helpppppp) ( MAP test question)
Answer:
The length of row = 3.2 inches.
Step-by-step explanation:
The length of a chocolate = 4/5 inch
Total number of chocolate pieces placed = 4
Now we have given the length of one chocolate and it is required to find the total length of the row when four chocolates are placed end to end. So in order to find the length of the chocolate row we have to multiply the size of one chocolate by the number of chocolates.
The length of row = Length of one chocolate × number of chocolates
The length of row = 4/5 × 4
The length of row = 3.2 inches.
The piece of chocolate and the number of chocolates in a row can be represented using equations.
A row of chocolate is 3.2 inches long
Given that:
[tex]L = \frac 45[/tex] ---- Length of a piece
[tex]n =4[/tex] --- number of chocolate pieces
The length of the chocolate in a row is calculated as follows:
[tex]Length = n \times L[/tex]
So, we have:
[tex]Length = 4 \times \frac 45[/tex]
[tex]Length = 4 \times 0.8[/tex]
[tex]Length = 3.2[/tex]
Hence, a row of chocolate is 3.2 inches long

A figure is located entirely in the third quadrant. If you reflect it over y = 0. Which quadrant will the resulting figure lie in?
Answer: Quadrant 2
=================================================
Explanation:
Check out the diagram below. An example point in the third quadrant is (-2,-5). This quadrant is the southwest quadrant. Reflect the example point over the x axis (aka the line y = 0) and we get (-2,5). This is shown when we go from point A to point B in the diagram.
The reflection rule is [tex](x,y) \to (x,-y)[/tex] showing that only the y coordinate changes from y to -y. If y is negative, then flip to positive, or vice versa. The x coordinate stays the same.
The point started in quadrant 3 and it moves to quadrant 2 after the reflection over the line y = 0.
Side note: all points on the line y = 0 have a y coordinate of 0

Write an equation of a line in point-slope and slope intercept form that passes through the point (1, -8) and is perpendicular to the line: 2x-4y = -11
Answer:
11y-2x= -90
Step-by-step explanation:
for the point (1,-8)
x=1 and y= -8
for the equation,
2x -4y= -11
x= -1/m
m= -1/x
x = -1/ (-11/2 )
m= 2/11
so for the equation,
y-y1= m(x- x1)
y- -8=2/11(x-1)
11(y+8)= 2(x-1)
11y +88= 2x-2
11y-2x= -90
