What is the slope of a line that passes
through the points (-1, 1) and (1, -15)?
Answer:
-8
Step-by-step explanation:
y2 - y1 / x2 - x1
-15 - 1 / 1 - (-1)
= -16 / 2
= -8
Write the equation of the line with slope -7/8 and y-intercept of -4/5
Answer:
y= -7/8 - 4/5
Step-by-step explanation:
y=mx+b
y= -7/8 + y intercept (b)
so y= -7/8 - 4/5

In a small town, there are 4 times as many left-handed males as there are left-handed females, and there are 3 times as many right-handed females as there are right-handed males. There are a total of 204 males and 348 females in the town.
Let x represent the number of left-handed females, and let y represent the number of right-handed males. Write a system of equations to represent the situation. What is the value of x, the number of left-handed females?

I can't think of any right answer?
Gina can trade empty bottles for money at the grocery store. She returned a few bottles worth $0.10 each and 6 bottles worth $0.05 each . The clerk paid Gina $0.80 for all of the bottles . How many bottles worth $0.10 did Gina return?
Answer:
5 bottles
Step-by-step explanation:
a total of $0.80 was paid
6 $0.05 bottles were returned= $0.05×6= $0.30
remainder= $0.80-$0.30= $0.50
amount of $0.10 bottles returned= $0.50÷$0.10= 5
How did my teacher get 70?- like I don’t understand
Answer:
Each triangle has angles and all of those angles add up to 180 degrees total. since both of those angles at the bottom are equal then their angles would each be 70.
Answer:
70
Step-by-step explanation:
180°-40°=140°
140°/2
=70

Which equation models the data?
Answer:
y = 800•1/2^x
Step-by-step explanation:
Looking at the table, we can see that as we have an increase in x values, y values are halved
This probably means that the table represents an exponential function
The general form of this is;
y = a•b^x
From the first point
800 = a*b^0
800 = a * 1
a = 800
Using the second point;
400 = 800 * b^1
b = 400/800
b = 1/2
So we have the equation as;
y = 800•1/2(^x)
What is the value of a ? (Round your answer to the nearest degree .)
Answer:
a = 32.28°
Step-by-step explanation:
In the given right triangle,
Opposite side = 12
Adjacent side = 19
By applying tangent rule in the given triangle,
tan(a°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(a°) = [tex]\frac{12}{19}[/tex]
a = [tex]\text{tan}^{-1}(\frac{12}{19})[/tex]
a = 32.28°

Consider the figure below.
Line segment AD, Line segment BE, and line segment CF are medians concurrent at G.
Which of the following statements is true?
A FG=1/2 GC
B ED=2/3 AB
C BG=1/2 BE
D GD=2/3 AD
Answer:
A: FG = ½GC
Step-by-step explanation:
Since AD, BC and CD are medians concurrent at G, it means G is the centroid.
Now, when median passes through the centroid, the centroid divides the median in the ratio of 2:1.
Also,that the median touches the side of the triangle at their midpoints.
Thus,by inspection, we can say that;
GD = ⅓AD
GC/FG = 2/1
Thus, GC = 2FG and FG = ½GC
BG = ⅔BE
Tbus,looking at the options given and what we have gotten in proof, we can say only FG = ½GC is correct.
Jason went swimming. He dives 1/7 of the distance from the diving board to the end of the swimming pool. Then, he swims 4/5 of the distance from the diving board to the end of the swimming pool. He estimated that he covered about 7/12of the distance from the diving board to the end of the swimming pool. Is Jason's estimate reasonable?
Answer:
no
Step-by-step explanation:
Total distance he could have swam from the diving board to the end of the swimming pool. = 1 - 1/7 = 6/7
If he swam 4/5 of it, total distance swam = 6/7 x 4/5 = 24/35
total distance covered = 1/7 + 24 /35 = 29/35

Answer:46%
Step-by-step explanation:
Answer:
23/50 or 46%
Step-by-step explanation:
I just added red and purple out of the total(red+purple/total=11+12/50=23/50)
then I multiplied the fraction by 2 to get out of 100 for the percentage(23/50*2=46/100=46%)

Step-by-step explanation:
please help:) see pic attached
Answer:
a. 7
b. 6
c. 5.2
d. 7
Step-by-step explanation:
a: The mode is the number that occurs the most. 7 occurs the most in the set.
B. I rearrange d the numbers in numerical order and then found the middle (where both sides surrounding the number are the same amount of numbers. This was 5 and 7 so to find the mean I added 5+7 and divided it by two to get the in between, 6!
c. I added all of the values and then divided them by the amount of total values in the data set.
so I did 1 + 2 +3+4+5+7+7+7+8+8 = 52
52/10 = 5.2
d. range is the greatest value by the least value. So I did 8 - 1 to get 7!

22 cm
Cylinder X
Cylinder Y
O A. 45 cm
OB.
712 cm3
O C.
178 cm3
Answer:
Volume of Cylinder X = 712 cm³
Step-by-step explanation:
Given:
Volume of Cylinder Y = 89 cm³
Radius of cylinder Y = 2 cm
Radius of cylinder X = 4 cm
Find:
Volume of Cylinder X
Computation:
We know that, Cylinder X and Cylinder Y are similar
So,
Volume of Cylinder X / Volume of Cylinder Y = [Radius of cylinder X / Radius of cylinder Y]³
Volume of Cylinder X / 89 = [4/2]³
Volume of Cylinder X / 89 = [2]³
Volume of Cylinder X / 89 = 8
Volume of Cylinder X = 8 x 89
Volume of Cylinder X = 712 cm³

What is v29?
Place a dot on the number line at the best approximation.
2.
3
4
5
6
Answer:
Please read explanations
Step-by-step explanation:
By direct calculations, we know that the nearest perfect square to 29 is 25
The next is 36;
Hence, since 29 is between 25 and 36; it is only proper that the square root of 29 is also between the square roots of both numbers
So, we can conclude that the square root is between 5 and 6
For actual values by calculating, we have this as 5.38 which to the nearest number is 5.4
so, we have the dot at the next 4 small lines after the number 5
