Seven year old students at a elementary school were given 10 yard
Answer:
The correct option is a. 10 ≤ x ≤ 60, or x is from 10 to 60.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Seven-year-old students at an elementary school were given a 10-yard head start in a race. The graph shows how far the average student ran in 30 seconds. A line graph with Distance, in yards, on the x axis and Age of Runner on the y axis. The x axis has a scale from 0 to 80 in increments of 10. The y axis has a scale of 0 to 8 in increments of 2. A straight line connecting 10, 7 and 60, 7 is drawn. Which statement best describes the domain of the function represented in the graph?
a. 10 ≤ x ≤ 60, or x is from 10 to 60
b. 7 ≤ x ≤ 60, or x is from 7 to 60
c. 7 ≤ x ≤ 10, or x is from 7 to 10
d. 0 ≤ x ≤ 10, or x is from 0 to 10
Note: See the attached photo for the graph referred to in the question.
The explanation of the answer is now given as follows:
In statistics, the domain of a function refers to the values in the x-axis where there is a corresponding value in the y-axis.
In this question, the only defined values for x are from 10 to 60 with a corresponding constant value of 7 in the y-axis.
Based on this, the correct statement that best describes the domain of the function represented in the graph is therefore option a. 10 ≤ x ≤ 60, or x is from 10 to 60.
Decide if the statement is giving you the x or y value of the function
Answer: 1a. f(2) is an x-value
1b. f(x) = 4 is a y-value
1c. f(-10) is an x-value
1d. m(x) = 64 is a y-value
2. f(4) = 17
3. x = 39
Step-by-step explanation: In general, if there is an equal sign, the output f(x) is a y-value. if the expression is f(#) with a number in the parentheses, that is the value to insert for x.
2.) f(x) = 2x + 9
f(4) = 2(4) + 9
f(4) = 8 + 9
f(4) = 17
3. f(x) = 5x -3
192 = 5x -3
192 + 3 = 5x
195 = 5x
39 = x

Use the table below to determine whether f(x) could represent a linear function If it could write f(x) in the form f(x)=mx+b
Answer:
f(x) = 6x - 5Step-by-step explanation:
We see f(x) increase is linear and is 6 at each step, so m = 6 and y-intercept is b = -5, from point (0, -5)
So the function is:
f(x) = 6x - 58th grade work

Which statement best describes the solution to this system of equations? 3x+y=17 X+2y=49
A. It has no solution.
B. It has infinite solutions.
C. It has a single solution: x= 15, y= 17.
D. It has a single solution: X=-3, y= 26.
Answer:
D. It has a single solution: X=-3, y= 26.
Step-by-step explanation:
3x + y = 17
x + 2y = 49 ➡ x = 49 - 2y now write this information in the first equation instead of x
3x + y = 17 ➡ 3(49 - 2y) + y = 17
147 - 6y + y = 17 add like terms
147 - 17 = 5y
130 = 5y divide both sides by 5
26 = y we can calculate the value of x using this information
3x + y = 17 ➡ 3x + 26 = 17 subtract 26 from both sides
3x = -9 divide both sides by 3
x = -3
Divide the fraction and then simplify to its lowest form.

Which of the follwing is true 3 3/9+7 6/11=10 87/99 2 3/8+6 4/5=8 12/40 ,3 3/7+4 2/3=7 2/21 4 5/6+5 5/7=9 10/13
Answer: 3 3/9+7 6/11 = 10 87/99
Step-by-step explanation:
a. 3 3/9+7 6/11 = 10 87/99
First and foremost, we need to know the lowest common multiple of 9 and 11 which is 99.
Therefore, 3 3/9 + 7 6/11 would be:
= 3 33/99 + 7 54/99
= 10 87/99
This is correct
b. 2 3/8 + 6 4/5 = 8 12/40
First and foremost, we need to know the lowest common multiple of 8 and 5 which is 40.
Therefore, 2 3/8 + 6 4/5 would be:
= 2 15/40 + 6 32/40
= 8 47/40
= 9 7/40
Since the answer gotten is 8 12/40. This is wrong.
c. 3 3/7 + 4 2/3 = 7 2/21
First and foremost, we need to know the lowest common multiple of 7 and 3 which is 21.
Therefore, 3 3/7 + 4 2/3 would be:
= 3 9/21 + 4 14/21
= 7 23/21
= 8 2/21
Since the answer gotten is 7 2/21. This is wrong.
d. 4 5/6 + 5 5/7 = 9 10/13
First and foremost, we need to know the lowest common multiple of 6 and 7 which is 42.
Therefore, 4 5/6 + 5 5/7 would be:
= 4 35/42 + 5 30/42
= 9 65/42
= 10 23/42
This is wrong as the answer gotten is 9 10/13
Therefore, the true option is
3 3/9+7 6/11 = 10 87/99

1. A survey was taken at Bernal Middle School to find out who their favorite teacher was. The survey asked 150 students and 90 of those students said Ms. Lancaster. What percent of the people surveyed voted Ms. Lancaster as their favorite teacher?
2. At the Mendoza's Thanksgiving there were 15 pecan pies. If 25% of there were eaten, how many pies were consumed?
3. 540 people were asked what their favorite ice cream flavor was and 45% of them chose chocolate. How many people chose chocolate?
1. 90/150 students voted Ms. Lancaster as their favorite teacher. If you divide 90 by 150, you get 0.6. 0.6 = 60% of students.
2. 25% of the 15 pecan pies were consumed, meaning 1 out of every 4 was eaten. 15/4, or 15 * 0.25 = 3.75 pies were consumed.
3. 45% of the 540 people said chocolate was their favorite ice cream flavor. To find the number of people, you can multiply 540 * 0.45 = 243 people chose chocolate.
y = -42 - 5
y = 3x - 2
Is (3, 7) a solution of the system?
Answer:
The answer is below
Step-by-step explanation:
Given that:
y = 4x - 5
y = 3x - 2
This problem can be solved graphically by plotting the graphs of both lines, and the x and y coordinate of the intersection of both lines would give the solution to the problem. Also, the problem can be solved simultaneously by:
Step 1: subtract the second line equation from the first line equation to get
0 = x - 3
x = 3
step 2: Put x = 3 in equation 1 to get
y = 4(3) - 5
y = 7
Therefore the solution = (x, y) = (3, 7)
claire mixes 2 1/2 cups of water with 1/3 cup of orange juice concentrate. Han mixes 1 2/3 cups of water with 1/4 cup of orange juice concentrate. whose orange juice mixture tastes stronger? explain and show your reasoning
Answer:
Han's mixture tastes stronger, because...
Han's uses 6 2/3 cups of water for every 1 cup of orange juice concentrate.
Clare uses 7 1/2 cups of water for every 1 cup of orange juice concentrate.
Step-by-step explanation:
Claire
Cups of water = 2 1/2 cups
Cups of orange juice = 1/3
Cups of water for every cup of orange juice = 2 1/2 ÷ 1/3
= 5/2 × 3/1
= 15/2
= 7 1/2
Han:
Cups of water = 1 2/3 cups
Cups of orange juice = 1/4 cups
Cups of water for every cup of orange juice = 1 2/3 ÷ 1/4
= 5/3 × 4/1
= 20/3
= 6 2/3

Answer:
d) [tex]4\cdot 10^{6}[/tex] times
Step-by-step explanation:
Scientific Notation
We are given two quantities and we must find the ratio between them and use scientific notation.
The diameter of a pearl is about
[tex]4\cdot 10^{-3}\ cm[/tex]
Converting to meters, we divide by 100
[tex]4\cdot 10^{-3} / 100 = 4\cdot 10^{-5}\ m[/tex]
The diameter of an atom is about
[tex]10^{-11}\ m[/tex]
The ratio between both diameters is:
[tex]\displaystyle \frac{4\cdot 10^{-5}\ m}{10^{-11}\ m}= 4\cdot 10^{-5+11}=4\cdot 10^{6}[/tex]
Answer: d) [tex]\mathbf{4\cdot 10^{6}}[/tex] times
Carl's mom made 25 mushrooms for Carl and 4 friends to eat for a snack. If each of them ate the same number, and they ate as many as possible, how many did each
one eat?
5
7
4
6
Step-by-step explanation:
they each had 25 mushrooms for Carl and his friends there are 4 of them each and they got the same portions and if you count by 5s to 25 that will be the answer so the answer is 5
Answer:
5
Step-by-step explanation:
Number of mushrooms = 25
Number of persons = 5
Each of them ate the same number of mushrooms. so the square root of 25 will be number of mushrooms eaten by each
Number of mushroom eaten by each of them = √25
= 5
The as-served cost of a kid's dinner special is $2.25. If the restaurant uses a target cost percentage of 35%, what is the target price of the kid's dinner special?
Answer:
$3.0375
Step-by-step explanation:
Original price of dinner = $2.25
If cost percentage of 35%, then the additional cost paid will be;
35% * 2.25
= 0.35 * 2.25
= $0.7875
Target price = Original price + additional cost
Target price = $2.25 + $0.7875
Target price = $3.0375
