Four candidates participated in a school election Bianca received 1/5 of the votes, Chelsea received 0.26 of the votes, Darell received 25% of
the votes, and Francisco received the rest of the votes. What percent of the votes did Francisco receive?
A 29% B 31% C 33% D 35%
Answer:
A - 29%
Step-by-step explanation:
Bianca's 1/5 would be converted to 20%
Chelsea's .26 would be 26%
Darnell's is 25%
Adding these together you get 71. To find the remaining votes that Francisco received you would..
Subtract
100 - 71 = 29%
Therefor, your answer is A.
If Darell earned 25% of the vote and Francisco received the remaining votes, Chelsea would have garnered 0.26 percent of the vote. 29% of the votes were cast in favor of Francisco. Option A is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Given that there were four candidates running for office in the school election, Bianca won 1/5 of the vote, Chelsea got 0.26, Darell got 25%, and Francisco got the remaining votes.
Bianca's 1/5 would be converted to 20% and Chelsea's .26 would be 26%, Darnell's is 25%
Adding these together you get 71. To find the remaining votes that Francisco received you would be applying the subtraction operations,
100 - 71 = 29%
Thus, if Darell earned 25% of the vote and Francisco received the remaining votes, Chelsea would have garnered 0.26 percent of the vote. 29% of the votes were cast in favor of Francisco. Option A is correct.

Answer:
A=14
Use formula A^2+B^2=C^2
Answer:
∠ A ≈ 24°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin A = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{MR}{AR}[/tex] = [tex]\frac{6}{15}[/tex] , thus
A = [tex]sin^{-1}[/tex] ([tex]\frac{6}{15}[/tex] ) ≈ 24° ( to the nearest degree )
To finish a project, you need to paint the lateral surfaces of a cube with side length 2.5 inches. Find the area that you need to paint.
Answer:
[tex]25 in^2[/tex]
Step-by-step explanation:
We want to find the lateral surface area of the cube.
The lateral surface area of a cube is given as:

Multiply
(2x + 4)(2x - 4)
Answer:
4x^2 -16
Step-by-step explanation:
(2x + 4)(2x - 4)
FOIL
first:2x*2x = 4x^2
outer: -4 *2x = -8x
inner: 4*2x = 8x
last: -4*4 = -16
Add them together
4x^2 -8x+8x =-16
4x^2 -16
The multiplication of the expression (2x + 4)(2x - 4) is 4x² - 16.
What is the simplified form of the expression?Given the expression in the question:
(2x + 4)(2x - 4)
We can multiply the expression (2x + 4)(2x - 4) using the distributive property and the FOIL method.
(2x + 4)(2x - 4)
Apply the FOIL method:
2x( 2x - 4 ) + 4( 2x - 4 )
Apply distributive property:
2x × 2x + 2x × - 4 + 4 × 2x 4 × - 4
Multiply the terms:
4x² - 8x + 8x - 16
Collect and add like terms:
4x² - 16
Therefore, the simplified form is 4x² - 16.

What is the area of the triangular part of the flag below
Describe the end of behavior
Answer:
Step-by-step explanation:
Recognize that this is the exponential function y = e^x with some tweaks:
f(x) = 2e^x + 1, as compared to y = e^x.
y = e^x is a basic function that we all should know well. Its graph looks much like the graph shown as "Part A." The graph starts in Quadrant II, crosses the y-axis into Quadrant I, and then continues growing rapidly as x increases.
As x => positive infinity, y => positive infinity. This is true of f(x) = 2e^x + 1 also.
As x => negative infinity, y => 0 (speaking of y = e^x).
As x => positive infinity, f(x) = 2e^x + 1 => positive infinity, in Quadrant I.
Which function describes the graph shown below?
On a coordinate plane, a curve crosses the y-axis at (0, negative 2), increases to negative 2.5, decreases to negative 2.5, and then increases again.
y = one-half sine (x) minus 2
y = 2 sine (x) minus one-half
y = one-half cosine (x) minus 2
y = 2 cosine (x) minus one-half

Two angles of a triangle measure 12° and 40°.
What is the measure of the third angle of the triangle?
Answer:
128
Step-by-step explanation:
The sum of angles in the triangle is 180 degrees
12 + 40 + x = 180
52 + x = 180
x= 180 - 52 = 128 degrees
(x is the third angle of the triangle)
The measure of the third angle of the triangle is 128degrees
The sum of an interior angle of a triangle is 180 degrees.
Let the third angle of the triangle be x, hence;
12 + 40 + x = 180
52 + x = 180
Subtract 52 from both sides
52 + x - 52 = 180 - 52
x = 180- 52
x = 128degrees
Hence the measure of the third angle of the triangle is 128degrees

Answer:
1) x = 7 y = 19 2) x = 1 y = 3
Step-by-step explanation:
1) y = 4x - 9
y = 2x + 5 Since the equations are equal to y, set them equal to each other
4x - 9 = 2x + 5
-2x - 2x Subtract 2x from both sides
2x - 9 = 5
+ 9 + 9 Add 9 to both sides
2x = 14 Divide both sides by 2
x = 7
Plug this into the first equation
y = 4(7) - 9 Multiply
y = 28 - 9 Subtract
y = 19
2) -3x + 6 = x + 2
+3x +3x Add 3x to both sides
6 = 4x + 2
-2 - 2 Subtract 2 from both sides
4 = 4x Divide both sides by 4
1 = x
Plug this into the second equation
y = 1 + 2 Add
y = 3

Rectangle WXYZ is shown on a coordinate plane. On a coordinate plane, a rectangle has 4 points. Point W is (1, 1), point X is (10, 1), point Y is (10, negative 3), and point Z is (1, negative 3). What is the length of side XY? units
Answer:
the length of the side XY is 4 units
Step-by-step explanation:
To find the length of side XY, what we do is to find the distance between the points X and Y
To find this distance, we employ the use of the formula for finding the distance between two points on a Cartesian plane.
Mathematically, the distance d which represents the length XY is given by;
d = √{(x2-x1)^2 + (y2-y1)^2}
Where point X represents the coordinates (x1,y1) = (10,1) while point Y represents the coordinates (x2,y2) = (10,-3)
Plugging these values into the formula, we have;
d = √{(10-10)^2 + (-3-1)^2}
d = √{(0)^2 + (-4)^2}
d = √(0 + 16)
d = √(16)
d = ± 4
but since distance cannot be negative, we ignore the -4 and thus we choose 4 units as the length between the points XY
Answer:
4 units

A drawer has 9 pairs of white socks 7 pairs of black socks 6 pairs of brown socks and 3 pairs of blue socks you get dressed each morning in the dark in randomly reach into the sock drawer to get your socks after a day of wearing the socks you do not replace them until the weekend after you have done some laundry what is the probability that your sock selection goes in the following order for this week?
P(Black then white then white the brown then blue)=____
Answer:
0.0014 = 0.14%
Step-by-step explanation:
First we need to find the total number of pairs:
9 + 7 + 6 + 3 = 25 pairs
Then, we need to find the probability for each case:
First socks black: 7 pairs over 25: P1 = 7/25
Second socks white: 9 pairs over 24: P1 = 9/24 = 3/8
Third socks white: 8 pairs over 23: P1 = 8/23
Fourth socks brown: 6 pairs over 22: P1 = 6/22 = 3/11
Fifth socks blue: 3 pairs over 21: P1 = 3/21 = 1/7
The final probability will the the product of all probabilities above:
P = (7/25) * (3/8) * (8/23) * (3/11) * (1/7) = 0.0014 = 0.14%
Answer:
567/398475 in fraction or 0.0014229249 in decimal
Step-by-step explanation:
In the question, we are given these values
Total pair of socks = 25 pairs of socks
9 pairs of white socks
7 pairs of black socks
6 pairs of brown socks
3 pairs of blue socks
From the question, we can see that, this is probability without replacement.
Hence,
P(Black then white then white the brown then blue)=
7/25 × 9/24× 8/23 ×6/22 × 3/21
= 9072/6375600
= 567/398475
Therefore, the Probability of picking a Black socks then white socks then white socks , then brown socks and then blue socks = 567/398475 in fraction or 0.0014229249 in decimal

The second column is labeled average household age under 40 with entries 54, 81, 135. the third column is labeled average household age 40 or older with entries 23, 92, 115. the fourth column is labeled total with entries 77, 173, 250. Madigan converts the frequency table to a conditional relative frequency table by row. Television Viewing Method A 4-column table with 3 rows titled Television Viewing Method. The first column has no label with entries internet, cable, total. The second column is labeled average household age under 40 with entries W, Y, 0.54.

Round to the nearest hundredth. 0.09 0.20 0.25 0.30
Answer:
For X they would have to divide the number from the first given chart for average household of the people that are ages 40 or under, which is 23, by the total internet, which is now 77.
