Answer:
42% can round to 40%, and 78 can round to 80. 40% of 80 is 32, so 42% of 78 should be about 32. 45 is much greater than 32, so the answer is not reasonable.

8:4 and 16:64 are equal ratios?
Hello.
In order to see if the ratios are equal, we have to simplify both of them.
The first ratio is 8:4.
Divide 8 and 4 by 4:
2:1
Now, simplify the second ratio:
16:64
4:16
1:4
Are 2:1 and 1:4 equal? No.
Therefore, 8:4 and 16:64 are not equal ratios.
I hope this helps.
Have a nice day.

How do you find the slope intercept form of the equation of the line through the points (-4,2) and (0,-5).
Answer:
[tex]y=-\frac{7}{4} x-5[/tex]
Step-by-step explanation:
How do you find the slope intercept form of the equation of the line through the points (-4,2) and (0,-5).
Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-5-2}{0-(-4)} =\frac{-5-2}{0+4}=\frac{-7}{4}=-\frac{7}{4}[/tex]
[tex]y = mx + b[/tex]
[tex]y=-\frac{7}{4} x-5[/tex]

Tell whether the angles are adjacent or vertical. Then find x
The Angles are adjacent and since they are both on a straight line it means that the sum of the angle is 180 degrees, so we get the equations:
[tex](6x) + (x - 2)=180\\7x = 182\\x=26[/tex]
So x = 26.

someone please answer this, ill give you brainliest and your getting 100 points.
Answer:
Step-by-step explanation:
First sequence : 10,9.5,9,8.5,...
Let's see the difference between 2 numbers :
10 - 9.5 = 0.5
9.5 - 9 = 0.5
9 - 8.5 - 0.5
So on and so on. So, the common difference between these numbers are 0.5
Next sequence : 200,100,50,25, ...
We see, to get from one number to another, we divide it by 2 / multiply it by 1/2.
200 x 1/2 = 100
100 x 1/2 = 50
50 x 1/2 = 25
So on and so on. So, the common ratio of these numbers are 1/2.
Answer:
Step-by-step explanation:
A common difference is the number you need to get from a chosen number on your left to get to the next number going right.
In the first sequence, you start with 10 on your left.
To get to the next number going right, you need to subtract 0.5 or add - 0.5
In any event, the common difference is -0,5
The second problem is a little harder. It does not follow the same sort of pattern that the first question does. This time you are multiplying or dividing.
200 * 1/2 = 100
100 * 1/2 = 50
50 * 1/2 = 25
25 * 1/2 = 13.5
So the common ratio is 1/2
convert into minute and second.
a. 270second
Answer:
There are 60 seconds per minute.
a) 270 seconds,
270 seconds/60 seconds (a single minute) = 4 minutes and 30 seconds
60 goes into 270, 4 times so that's 4 whole minutes with a remainder of 30 seconds.

have a nice day
Step-by-step explanation:
Answer:
√a² = |a|
Step-by-step explanation:
√a² = |a| not a
because the amount of "a" can be negative and when it reaches power 2 the minuse sign converts to plus sign , so we must use absolute value : |a| . notice that the answer never can be negative.
example:
a = -2
√(-2)² = √+4 = |-2| = 2 -2
Tony started to run on a treadmill after setting it’s timer for 78 minutes the display says he finished 78% of his run how many minutes have gone by round your answer to the nearest tenth
Answer:
60.9
Step-by-step explanation:
When finding the amount of a percentage you move the decimal to the left twice in the percentage.
So, 78 x .78 = 60.84
Since it needs to be rounded to the nearest tenth, the answer would be 60.9 minutes.

find the measure of each angle indicated (30 points)
Answer:
? = 20°
Step-by-step explanation:
This is if 25 is to the right.
Consider the following figure where △ABC ~ △DBE.
Triangle A B C contains two points and a horizontal line segment.
The left side of the triangle starts at vertex A, travels up and to the right, and ends at vertex B.
The right side of the triangle starts at vertex B, travels down and to the right, and ends at vertex C.
The bottom side of the triangle is horizontal, starts at vertex A on the left, and ends at vertex C on the right.
Point D is located on side A B but is closer to A than B.
Point E is located on side B C but is closer to C than B.
The horizontal line segment extends from point D and ends at point E.
Given:
CB = 12, CE = 2, AD = 5
Find:
DB
(Hint: Let DB = x, and solve an equation).
DB =
Given that △ABC and △DBE are similar triangles, the length of DB is: 25
What are Similar triangles?The ratio if the corresponding sides of two triangles that are similar are the same, meaning, their sides are proportional.
Given that:
△ABC ~ △DBECB = 12CE = 2AD = 5Thus:
Let DB = x
Therefore:
BD/BA = BE/CB
Substitute
x/(x + 5) = 10/12
Cross multiply
12x = 10x + 50
12x - 10x = 50
2x = 50
x = 25
Therefore, given that △ABC and △DBE are similar triangles, the length of DB is: 25

The initial amount of the function is 11, and then it decreases by a factor of 5/8
with each unit increase in x.
The function that describes the situation is y = ?
The linear function that represents the situation where is expressed as: y = 5/8x + 11.
What is a Linear Function?Given a relation that has initial value as b and m as the unit rate, a linear function that represents the relation is expressed as: y = mx + b.
Given:
Unit rate = m = 5/8Initial value = b = 11Substitute the values into y = mx + b.
y = 5/8x + 11
