Answers

It rises 15 and goes over 10.  Slope is rise/run.  So 15/10 or 3/2.  
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.

Ques 2)

We know that solution of a system of equation is the point where the two system meet if it has a unique solution.

From the graph of the system of equation we could observe that the two lines intersect each other in the second quadrant and we know that the point in the second quadrant has x-value negative and y-value positive.

Hence, the point that is the solution of the given system of equations is:

Bill has 2/3 of his pizza left from lunch. If he eats 3/7 more of the pizza, how much pizza is left?

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.

painter A charges $376 plus $12 per and painter B charges $280 plus $15 per hour. in how many hours will they cost the same

Answers

In 32 hours they will cost the same

Answer:

32 hours

Step-by-step explanation:

Let after x hours the charges of A and B are same,

Given,

For painter A,

Fixed charges = $ 376,

Additional charges per hour = $ 12,

So, the total charges for x hours = ( 376 + 12x ) dollars

For painter B,

Fixed charges = $ 280,

Additional charges pet hour = $ 15,

So, the total charges for x hours = ( 280 + 15x ) dollars

Thus,

376 + 12x = 280 + 15x

12x - 15x = 280 - 376

-3x = -96

x = 32

Hence, for 32 hours their cost will be same.

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.

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]

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.

I have 453 grams of strawberries I have 23 grams left how many grams of strawberries are left

Answers

The answer is 430 :)

To find out how many grams of strawberries are left, subtract the used grams from the total grams. Therefore, 430 grams of strawberries are left.

To determine how many grams of strawberries are left, we need to subtract the remaining grams from the total amount:

Start with the total weight of the strawberries: 453 grams. Subtract the amount already used: 453 grams - 23 grams. Calculate the result: 453 grams - 23 grams = 430 grams.

So, 430 grams of strawberries are left.
