You and two friends are playing basketball. You make 7 out of 15 shots. Your first friend makes 6 out of 10 shots and your second friend makes 5 out of 12 shots. Who is the better shooter? How would you solve this problem using what you know about rational numbers?

Answers

First, you will need to find the percentage of shots made for each person, or you can find the least common denominator. This is because it makes it easier to see how the numbers compare to each other in size. You can find the percentage of shots made by looking at how many shots a person made and dividing it by the total shots that person made, which us the denominator. Then, you would take the decimal and move it two places to the right. Once you find the percentages of all three people, you can then compare the percentages to each other. In this case, the higher the percentage, the better the shooter that person is.

The rate is the difference in pressure divided by the difference in depth.
It's finding the slope between two points (depth, pressure).

rate = (pressure 2 - pressure 1)/(depth 2 - depth 1)

rate = (44.4 - 29.55)/(66 - 33) = 14.85/33 = 0.45

The rate is 0.45 psi/ft.

Answers

Final answer:

The mathematical pattern involves starting with the number 5, multiplying by 3, and subtracting 2, which gives the sequence: 5, 13, 37, 109, 325.

Explanation:

The pattern described would involve starting with the number 5 and repeatedly applying the same mathematical operation, which is to multiply by 3 and then subtract 2, stopping after obtaining five numbers in total. Let's demonstrate this step-by-step:

Start with 5Multiply by 3: 5 × 3 = 15Subtract 2: 15 - 2 = 13 (This gives us our second number)Now use 13: 13 × 3 = 39Subtract 2: 39 - 2 = 37 (Third number)Next, take 37: 37 × 3 = 111Subtract 2: 111 - 2 = 109 (Fourth number)Finally, use 109: 109 × 3 = 327Subtract 2: 327 - 2 = 325 (Fifth number)

So the series of five numbers created by this pattern is: 5, 13, 37, 109, 325.

Relationship A has a greater rate than Relationship B. This table represents Relationship B.
Hours worked 2 4 5 8
Amount paid ($) 25 50 62.50 100

Which equation could represent Relationship A?

Hours worked is represented by x and Amount paid is represented by y.

Select each correct answer.

y = 13x
y = 11.5x
y = 12.75x
y = 12.25x

Answers

Answer:

y = 13x ; and y = 12.75x

Explanation:

The rate of change is another name for slope.  To find the slope of Relationship B, we use the formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Using the first two points, we have

m = (50-25)/(4-2) = 25/2 = 12.5

This means that anything with a rate of change greater than 12.5 works in this problem.

The equations listed for Relationship A are in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept (in all of these, b = 0).

In the first equation, m = 13; in the second equation, m = 11.5; in the third equation, m = 12.75; and in the fourth equation, m = 12.25.  The only ones with higher slopes than Relationship B are the first and the third one.

Which is an equation in point-slope form of the line that passes through the points (4, 5) and (−3, −1) ?
a. y−1=6/7(x−3)

b. y+1=6/5(x+3)

c. y+3=7/6(x+1)

d. y+1=6/7(x+3)

Answers

the slope (m) is (5 - -1) / 4 --3 = 6/7

y - y1 = (6/7)(x - x1)

y -  -1 = (6/7)( x - -3)

y + 1 = 6/7(x + 3)

Beau's recipe for granola bars calls for 3 1/2 cups of oatmeal. He only has a 1/6 cup scoop. How many scoops of oatmeal will he need to complete the recipe?

Answers

There will be [tex]\boxed{\bf 21}[/tex] scoops of oatmeal to complete the recipe.

Further explanation:

Given that Beau’s recipe of granola bars contains [tex]3\frac{1}{2}[/tex] cups of oatmeal.

Beau’s has only [tex]\frac{1}{6}[/tex] cup scoop.

Our aim is to find the number of scoops of oatmeal Beau’s needed to complete the recipe for granola bars.

Total cups of oatmeal are [tex]3\frac{1}{2}[/tex].

First we have to convert the total cups of oat meal to proper fraction.

[tex]\begin{aligned}\text{Cups of oatmeal for the recipe}&=\dfrac{(3\cdot 2)+1}{2}\\&=\dfrac{6+1}{2}\\&=\dfrac{7}{2}\end{aligned}[/tex]  

There is only [tex]\frac{1}{6}[/tex] cup scoop.  

Since there are [tex]\frac{7}{2}[/tex] cups of oatmeal and [tex]\frac{1}{6}[/tex] cup scoop, therefore, number of scoops required to complete the meal are calculated as follows:

[tex]\begin{aligned}\text{Number of scoops required}&=\dfrac{\frac{7}{2}}{\frac{1}{6}}\\&=\dfrac{7}{2}\cdot 6\\&=7\cdot 3\\&=21\end{aligned}[/tex]  

The total number of scoops is obtained in whole number; therefore, this is our final answer.

Therefore, [tex]\boxed{\bf 21}[/tex] scoops of oatmeal are needed by Beau’s to complete the recipe of granola bars.

Explanation:

The number of cups of oatmeal that are called for the recipe are [tex]3\dfrac{1}{2}.[/tex]

Solve the improper fraction [tex]3\dfrac{1}{2}[/tex] to obtain the proper fraction.

[tex]\begin{aligned}{\text{Fraction}}&= \frac{{2 \times 3 + 1}}{2}\\&=\frac{{6 + 1}}{2}\\&= \frac{7}{2}\\\end{aligned}[/tex]

The Beau has [tex]\dfrac{1}{6}{\text{ scoop}}.[/tex]

The number of scoops that are required to complete the recipe can be obtained as follows,

[tex]\begin{aligned}N&=\dfrac{{{\text{total cups of oatmeal}}}}{{{\text{the fraction of scoop Beau has}}}}\\&=\dfrac{{\dfrac{7}{2}}}{{\dfrac{1}{6}}}\\&= \frac{7}{2} \times 6\\&=\dfrac{{42}}{2}\\&= 21\\\end{aligned}[/tex]

The number of scoops required to complete the oatmeal is [tex]21{\text{ scoops}}.[/tex]

Therefore, [tex]\boxed{21}[/tex] number of scoops of oatmeal will he need to complete the recipe.

Two containers, A and b begin with equal volumes of liquid. 120 mL is then poured from a to B. Container b now contains four times as much liquid as A. Find the volume of liquid left in container a at the end

Answers

2u =120ml
1u=60ml
Answer:60ml
I think this is the answer

The volume of liquid left in container a at the end is 80 mL.

Let's denote the initial volume of each container as ( V ) mL. After pouring 120 mL from A to B, the volume of liquid in A decreases to ( V - 120 ) mL and the volume in B increases to ( V + 120 ) mL.

We're given that after this transfer, the volume in B is four times the volume in A:

[tex]\[ V + 120 = 4(V - 120) \][/tex]

Now, we solve for ( V ):

V + 120 = 4V - 480

120 + 480 = 4V - V

600 = 3V

V = [tex]\frac{600}{3}[/tex] = 200

So, the initial volume in each container was 200 mL. After pouring, A has ( 200 - 120 = 80 ) mL left.

Two scientists are measuring lava temperatures. One scientist records temperature of 1725 degrees Fahrenheit. The other scientist records a temperature of 950 degrees Celsius. Which is the greatest temperature? (Use C= 5/9(F - 32)

Answers

We will convert all units to degree Celcius in order to be able to compare the values.
We are given the following relation:
T(°C) = (T(°F) - 32) × 5/9

Therefore:
Scientist 1 records a temperature of  1725 degree Fahrenheit which is equivalent to:
T(°C) = (1725 - 32) × 5/9 = 940.556 degrees celcius
Scientist 2 records a temperature of 950 degrees celcius.

By comparing the values, we will find that the temperature measured by scientist 2 has a greater value.


Final answer:

To compare temperatures, convert them to the same unit. In this case, 1725°F is the greatest temperature between 1725°F and 1742°F.

Explanation:

Converting temperatures: To compare temperatures, we must convert them to the same unit. The first scientist recorded 1725°F, and the second scientist recorded 950°C. Converting 950°C to Fahrenheit, we get 1742°F. Therefore, 1725°F is the greatest temperature.
