Try and remember your place values!

An easy way is that smaller numbers, have larger names (im sure there are other ways!)

0.1 - tenths (like how one place value after 1 is tens)
0.01 - hundredths (2 place values after 1 is hundred)
etc.

Also remember that 10 of one place value will be 1 of the next up.

How is finding a unit rate similar to solving a proportion

Answers

the both involve Fractions

A unit rate is a quantity per one unit. For example, miles per hour (mi/h). The "one unit" is 1 hour.
However, 10 miles per 2 hours (10 mi/2h) would not be a unit rate because it is per 2 hours, not 1. The unit rate for 10 mi/2h would be 5 mi/h.

You can find the unit rate by simply dividing the numerator by the denominator. (The fraction bar is a division bar!)
In simplifying 10 mi/2h, I divided the numerator (10mi) by the denominator (2h).
10 divided by 2 is 5, so the unit rate is 5 mi/h.

You can also think of this as a proportion. Because for the unit rate you need to find the new quantity over one unit of measurement, the new rate is x over one hour.
[tex]\frac{10mi}{2h} = \frac{x}{h} \\ \\ (2h)x = (10mi)h \\ x = 5mi/h[/tex]

A) 1/4
B) 1/3
C) 1/21
D) 5/21

Answers

he has eaten 7/21 already. if he eats 9/21 from the 14/21 left, he will have 5/21 left. the answer is d

Answer:

Option D) 5/21 pizza is left.

Step-by-step explanation:

Bill has 2/3 of his pizza left from lunch. If he eats 3/7 more of pizza then we have calculate the pizza left.

Let the size of a pizza is x. Now 2x/3 pizza is left with Bill after lunch.

Therefore pizza eaten by Bill = x - 2x/3 = x/3

Now Bill eats 3/7 more of pizza has been eaten by Bill.Therefore total pizza left is

x - x/3 - 3x/7 = x(1 - 1/3 - 3/7) = x( 21 - 7 - 9)/21 = 5x/21

So 5/21 part of pizza is left.

Which table could be a partial set of values for a linear function?

Answers

The fourth one because both the x and y variables increase at the same rate.

Answer:

Table 4

Step-by-step explanation:

As we know that

A Linear function is the one whose graph represents a line OR value of its dependent and independent variable change at a rate which remains constant throughout.

Now in the fourth table the values of x and y are given as show below:

x y

0.0 0.0

1 0.5

2 1.0

3 1.5

As we can see as the value of x increases by 1 from its previous value the value of y increases by 0.5 from its previous value. This trend remains the same throughout the given table.

So, we can say the partial set of values given table 4 represent the Linear Function

The solution to #2 is where they intersect. (-2,1)

Answer:

Ques 1)

B) 3/2

Ques 2)

B) (-2,1)

Step-by-step explanation:

Ques 1)

We know that the coordinates of points S are (-2,-8)

and the coordinates of the point Q are: (8,7)

We know that the slope of a line passing segment with end points (a,b) and (c,d) are given as:

[tex]slope=\dfrac{d-b}{c-a}[/tex]

Here we have:

(a,b)=(-2,-8) and (b,d)=(8,7)

Hence, the slope is:

[tex]Slope=\dfrac{7-(-8)}{8-(-2)}\\\\Slope=\dfrac{7+8}{8+2}\\\\Slope=\dfrac{15}{10}\\\\Slope=\dfrac{3}{2}\\(Since\ both\ the\ numerator\ and\ denominator\ are\ divisible\ by\ 5)[/tex]

Hence, the slope of a line connecting point S to point Q is:

3/2.

Andy has 5 pots, and each pot can hold 3/8 pound of soil. How much soil does he need to fill all of the pots?

Answers

Final answer:

Andy needs 1.875 pounds or 15/8 pounds of soil to fill all his pots. This is found by multiplying the weight of soil one pot can hold (3/8 pound) with the total number of pots (5).

Explanation:

This question relates to the topic of multiplication in mathematics. It requires you to find the total weight of soil needed to fill all of Andy's pots. Every pot holds 3/8 of a pound of soil. To find out how much soil Andy needs, we can multiply the weight one pot can hold by the total number of pots.

Here are step-by-step instructions:

First, identify the amount that one pot can hold, which is 3/8 of a pound of soil.Next, find out how many pots Andy has, which is stated as 5 pots.To find the total amount of soil required, multiply the amount per pot with the total number of pots (3/8 * 5).

The answer will be 15/8 pounds or if you prefer decimals, 1.875 pounds of soil is needed to fill all the pots.

Jane Andrew and Maria pick apples Andrew picks three times as many pounds is Maria Jane picks two times as many pounds is Andre the total weight of the Apple's is 840 pounds how many pounds of the apples does Andre pick.

Answers

To solve the apple picking problem, we assigned variables and formulated an equation based on the relationships between the amounts each person picked. Solving the equation revealed that Andrew picks 252 pounds of apples.

Let Maria's apple pick be x pounds. According to the question, Andrew picks three times as many apples as Maria, which makes Andrew's pick 3x pounds. Jane, on the other hand, picks two times as many apples as Andrew, resulting in Jane's pick being 2(3x) or 6x pounds. Now, we know that the total weight of the apples picked by all three is 840 pounds.

We can express this as an equation:

x + 3x + 6x = 840

This simplifies to 10x = 840.

To find x, we divide both sides by 10:

x = 840 / 10

x = 84 pounds

Since Andrew picks 3x pounds, we multiply 84 by 3 to find Andrew's pick:

Andrew's pick = 3 × 84 = 252 pounds of apples.
