D'Andrea and Eden had a sit-up contest. D'Andrea did 176 sit-ups in 4 minutes. Eden did 215 sit-ups in 5 minutes. Which athlete did the most sit-ups per minute?
Answer:
Eden
Step-by-step explanation:
Answer:
it has D'Andrea
Step-by-step explanation:
Because here we are using direct variation and the formula is y=kx and k=y/x. I used k=y/x You divide 176 by 4 and you'll get 44 that's D'Andrea and the you divide 215 by 5 and you get 43 for Eden. you can see you does more sit up

Factorise x cube -2x square -5x plus 6
Answer: {(x + 2), (x - 1), (x - 3)}
Step-by-step explanation:
Presented symbolically, we have:
x^3 - 2x^2 - 5x + 6
Synthetic division is very useful for determining roots of polynomials. Once we have roots, we can easily write the corresponding factors.
Write out possible factors of 6: {±1, ±2, ±3, ±6}
Let's determine whether or not -2 is a root. Set up synthetic division as follows:
-2 / 1 -2 -5 6
-2 8 -6
-----------------------
1 -4 3 0
since the remainder is zero, we know for sure that -2 is a root and (x + 2) is a factor of the given polynomial. The coefficients of the product of the remaining two factors are {1, -4, 3}. This trinomial factors easily into {(x -1), (x - 3)}.
Thus, the three factors of the given polynomial are {(x + 2), (x - 1), (x - 3)}

baker has 5\dfrac145 4 1 5, start fraction, 1, divided by, 4, end fraction pies in her shop. She cut the pies in pieces that are each \dfrac18 8 1 start fraction, 1, divided by, 8, end fraction of a whole pie.
Answer:
The answer is "She cut a total of 42 pieces of pie".
Step-by-step explanation:
Given :
Total pie= [tex]5 \frac{1}{4}[/tex]
cut pie = [tex]\frac{1}{8}[/tex]
The number of pieces of the pie she has=?
Solve the mixed fraction value:
[tex]\to 5 \frac{1}{4}= \frac{21}{4}[/tex]
If she cuts the pieces into the entire pie, that is = [tex]\frac{1}{8}[/tex]
So, the equation is:
[tex]\to \frac{21}{4} = \frac{1}{8} \times x[/tex]
[tex]\to x= \frac{21 \times 8}{4}\\\\ \to x= 21 \times 2\\\\ \to x=42[/tex]

Ms. Geetha said that 60 of her total students will compete in the Math Olympics. If 60 is 20% of her students, how many total students does she have?
Answer:
300 students
Step-by-step explanation:
There are two ways to solve this question.
Way Number 160 is 20% of the total students
20÷100= 0.2
60÷0.2=300
Therefore there are 300 students
Way Number 260 is 20% of the total students
60/20 = x/100
x= 60*100÷20
x= 6000÷20
x= 300
Therefore there are 300 students.

if you earn $35 in 5 hours, how much money will you earn in 17 hours? how much will you earn in 1 hour?
Answer:
$119, $7.
Step-by-step explanation:
First, we need to find the unit rate of pay, in dollars.
Divide $35 by 5 to get $7 per hour.
Now, we multiply the unit rate of pay by 17 to find out how much money is made in the 17 hours that were worked.
By doing this, we get the answer: $119.

What is the y-intercept of the line?
Answer:
The Y-intercept is 1
It is where the line meets the y-axis
~PumpkinSpice1
[tex]==================================[/tex]
Remember, the y-intercept is the point where the graph touches the y-axis (that's why it's called y-intercept).
Let's look at this graph and see if we can identify the y-intercept of the line.
If we look at our graph, we'll see that the line touches the y-axis at (0, 1).
[tex]\pmb{Note:-}[/tex] Remember, y-intercepts have an x-coordinate of 0.
And guess what the y-coordinate is? Yes, it's the y-intercept of the line.

38 marbles are shared between John, David and Paul so that John gets twice as many as David. Paul gets 5 only. How many marbles does john get?
Answer:
11
Step-by-step explanation:
The total number of marbles John gets is 22 and this can be determined by forming the linear equation with help of the given data.
Given :
38 marbles are shared between John, David, and Paul so that John gets twice as many as David. Paul gets 5 only.The following steps can be used in order to determine the total number of marbles john gets:
Step 1 - Let the total number of marbles John have to be 'x', let the total number of marbles David have to be 'y', and let the total number of marbles Paul have to be 'z'.
Step 2 - So, the linear equation that represents the total number of marbles is:
x + y + z = 38 --- (1)
Step 3 - According to the given data, John gets twice as many as David, that is:
x = 2y --- (2)
Step 4 - According to the given data, Paul gets only 5 marbles, that is:
z = 5 --- (3)
Step 5 - Substitute the value of x and z in equation (1).
2y + y + 5 = 38
Simplify the above equation.
3y + 5 = 38
3y = 33
y = 11
Step 6 - Substitute the value of y in equation (2).
x = 2(11)
x = 22
So, the total number of marbles John gets is 22.

Step-by-step explanation:
Given two points, we can find the equation of the line between them with the following:
[tex]y = mx + b\\m = \frac{y_2-y_1}{x_2-x_1}[/tex]
First, we can calculate m, or slope
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-0}{1-(-4)} = \frac{5}{5} = 1[/tex]
Next we can use the top equation and solve for b, the y-intercept

Answer:
[tex]\huge\boxed{\sf 126\° \ OR \ 145 \°}[/tex]
Step-by-step explanation:
m∠4 + m∠7 = 180 (Adjacent Angles of a parallelogram)
Given that m∠4 = x + 45, m∠7 = x² + 45
x + 45 + x² + 45 = 180
x² + x + 90 = 180
x² + x = 180 - 90
x² + x = 90
x² + x - 90 = 0
Using mid-term break formula
x² + 10x - 9x - 90 = 0
x(x+10) - 9(x+10) = 0
(x - 9)(x + 10) = 0
Either,
x-9 = 0 OR x+10 = 0
x = 9 OR x = -10
[tex]\rule[225]{225}{2}[/tex]
Now,
m < 7 = x² + 45
For x = 9
m < 7 = (9)² + 45
m < 7 = 81 + 45
m < 7 = 126°For x = -10
m < 7 = (-10)² + 45
m < 7 = 100 + 45
m < 7 = 145°[tex]\rule[225]{225}{2}[/tex]

Answer:
1. 795, 23
2. 50, she will finish her candy on November 21 so she won't be able to share with her cousins
3. $276, 71 cars
Step-by-step explanation:
1. your equation: y = 35x + 235
plug in 16 to find how many pictures she will have on may 16: y = 35(16) + 235
you get y = 795
for the second part, you know are trying to find how long it will take to get to 1024 pictures, so you know your y, but you don't know your x
your equation: 1024 = 35x + 235
solve to get x = 22.54
this rounds up to 23, so your answer is 23
2. multiply 8 times 4 to get 32
subtract 32 from 82 to fin how many she has left
you get 50
for the second part, divide 82 by 4 to find how many day it will take to finish her candy
you get 20.5
so no, she will not have candy to share with her cousins, and she will finish her candy on November 21
3. for this, you have a negative y intercept since you need to make $24 to start profiting
your equation: y = 6x - 24
plug in 50 to x: y = 6(50) - 24
you get y = 276
so you make $276 with 50 cars
for the second part, plug in 400 to y: 400 = 6x - 24
solve to get x = 70.66
this rounds up to 71, so your answer is 71
A train is traveling at a constant speed and goes 7.5 kilometers in 6 minutes. At that rate:
How far does the train go in 1 minute?
how far does the train go in 100 minutes?
Answer:
1.25 km in 1 minute
125 km in 100 minutes
Step-by-step explanation:
Find its speed in km/min by dividing the km by number of minutes:
7.5/6
= 1.25
So, the train goes 1.25 km in 1 minute.
Using this speed, find how far it goes in 100 minutes, by multiplying the speed by 100:
1.25(100)
= 125
So, in 100 minutes, the train goes 125 km.
a. The distance travelled by the train in 1 minute, at a constant speed is 1.25 kilometers.
b. The distance travelled by the train in 100 minute, at a constant speed is 125 kilometers.
Given the following data:
Distance = 7.5 kilometersTime = 6 minutesTo find how far (distance) the train go in 1 minute, we would use direct proportion:
7.5 kilometers = 6 minutes
X kilometers = 1 minute
Cross-multiplying, we have:
[tex]6 \times X = 7.5\\\\X = \frac{7.5}{6}[/tex]
X = 1.25 kilometers.
b. To find how far (distance) the train go in 100 minute:
Since the train travels 1.25 kilometers in 1 minute, we would multiply that distance by 100.
[tex]D(100) = 1.25 \times 100\\D(100) = 125 \; kilometers[/tex]
Distance = 125 kilometers.
