If X = 13 units, Y = 15 units, and h = 11 units, what is the area of the parallelogram shown above?
Answer:
the area of the parallelogram = base times the height
For the given parallelogram :
x = 8 units, y = 13 units, and h = 11 units
1) If x is the perpendicular to h
So, the base = 8 and the height = 11
So, the area = 8 * 11 = 88 square units
2) If y is the perpendicular to h
So, the base = 13 and the height = 11
So, the area = 13 * 11 = 143 square units

Selma uses a jogging trail that runs through a park near her home. The trail is a loop that is of a mile long. On Monday, Selma ran the loop in of an hour. What is Selma's unit rate in miles per hour for Monday's run?
Answer:
4.5 miles per hour
Step-by-step explanation:
Selma uses a jogging trail that runs through a park near her home. The trail is a loop that is 3/4 of a mile long. On Monday, Selma ran the loop in 1/6 of an hour. What is Selma's unit rate in miles per hour for Monday's run?
Distance = 3/4 of a mile
Time taken on Monday = 1/6 of an hour.
What is Selma's unit rate in miles per hour for Monday's run?
Unit rate in miles per hour for Monday's run = distance ÷ time taken
= 3/4 ÷ 1/6
= 3/4 × 6/1
= (3 * 6) / (4 * 1)
= 18/4
= 4.5 miles per hour
Unit rate in miles per hour for Monday's run = 4.5 miles per hour
Find the area of the circle.
Answer:
153.86
Step-by-step explanation:
So first off, what is the formula for finding area of a circle?
Its [tex]\pi r^{2}[/tex]
We know that r(radius), is the distance from one point of the circle to its center.
In this case it is 7.
Note that in other cases, you might see a line going strait through the middle of the circle.
This is the diamater, and is 2x the radius. If you see the diamater, divide it in half, and you will find radius.
Now, back to the problem.
We know our radius is 7, so lets plug that into [tex]\pi r^{2}[/tex]:
[tex]\pi *7^{2}[/tex]
=
[tex]\pi *49[/tex]
=
153.93
So tecnically, this test is wrong. THe actual answer is .07 bigger than what they give.
However, it is the only possible answer, so it is correct.
Answer:
153.86

Find measure of angles B, E, D and C and the length of BC.
Triangle ABC ~ Triangle DEF. Measure of angle A = 30 degrees and measure of angle F = 65 degrees. AB=20, DE = 35, EF= 28.
Answer:
< B = 180-30-65=85°
< E = 85°
< D = 30°
< C = 65°
BC = 20/35 × 28 = 16
Answer:
<D = 30
< C = 65
<B = <E = 85
16 = BC
Step-by-step explanation:
ABC ~ Triangle DEF
<A = <D = 30
< C = <F = 65
Since they are similar triangles
A+ C + B = 180 since the angles of a triangle = 180
30+65+B =180
95+ B = 180
<B = 180 -95 = 85
<B = <E = 85
The triangles are similar so the sides are proportional
AB BC
---- = ---------
DE EF
20 BC
---- = ---------
35 28
Using cross products
20*28 = 35 BC
Divide each side by 35
20*28/35 = 35/35 BC
16 = BC

plzz help me with the correct ans find x
Answer:

Step-by-step explanation:
Since, triangle ABC is the enlargement of triangle XYZ.
[tex] \therefore \triangle ABC \sim \triangle XYZ[/tex]
So, corresponding sides of both the triangles would be in proportion.
[tex] \therefore \frac{x}{6}=\frac{25}{10}[/tex]
[tex] \therefore x= \frac{6\times 25}{10}[/tex]
[tex] \therefore x =\frac{150}{10}[/tex]

Why would the answer be 3.?
Answer: Cause why not?
Step-by-step explanation:
[tex]3(4x-1)=-2x+19+8x-4[/tex]
First combine like terms:
[tex]3(4x-1)=(-2x+8x)+(19-4)\\\\3(4x-1)=6x+15[/tex]
Now distributive property
[tex](3)(4x)-(3)(1)=6x+15\\12x-3=15+6x[/tex]
Additive Property of Equality
[tex]12x-3+3=15+6x+3\\12x=18+6x[/tex]
Subtractive Property of Equality
[tex]12x-6x=18+6x-6x\\6x=18[/tex]
And finally Division Property of Equality
[tex]\frac{6x}{6} =\frac{18}{6} \\x=3[/tex]
(5x-3)=(3x+27) I dont understand
Answer:
x = 15
Step-by-step explanation:
(5x-3)=(3x+27)
Subtract 3x from each side
(5x-3x-3)=(3x-3x+27)
2x-3 = 27
Add 3 to each side
2x-3+3 = 27+3
2x= 30
Divide by 2
2x/2 = 30/2
x = 15

What is the measure of the sides of a square with an area of 49 inches
Someone please answer fast ❤️
Answer:
7 inches
Step-by-step explanation:
area of square=l^2
49=l^2
[tex]\sqrt{49[/tex]=l
7=l
therefore the sides of a triangle is 7 inches.
Answer:
7
Step-by-step explanation:
So to find this you know a square has 4 equal sides. The area is 49, and area is side length multiplied by side length. So what number multiplied by itself is 49? 7 x 7=49!
The graph of a linear function passes through the
points (2, 11) and (6,21).
Write an equation for the function.
Use the number pad to enter numbers in the boxes.
y me
| x2 +
Answer:
y = 5/2x + 6
Step-by-step explanation:
Find the slope:
[tex]m=\frac{y_1-y_2}{x_1-x_2}\\\\m=\frac{11-21}{2-6}\\\\m=\frac{-10}{-4}\\\\m=\frac{5}{2}[/tex]
Use point-slope form to find the equation in slope-intercept form:
[tex]y-y_1=m(x-x_1)\\\\y-11=\frac{5}{2} (x-2)\\\\y-11=\frac{5}{2}x-5\\\\y=\frac{5}{2}x+6[/tex]
The equation of the line for the function will be y = 5/2x + 6.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the graph of a linear function passes through points (2, 11) and (6,21).
Slope = ( 21 - 11 ) / ( 6 - 2 )
Slope = 10 / 4
Slope = 5 / 2
The y-intercept will be calculated as:-
y = mx + c
y = ( 5 / 2 )x + c
11 = ( 5 / 2 ) x 2 + c
c = 11 - 5
c = 6
The equation of the line will be:-
y = mx + c
y = (5/2)x + 6

If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student.
C.
If there are 30 students in the class, the total number of blue marbles selected should be about 18 but may be more or less.
D.
It is possible that every student selects a green marble.
E.
If the total number of red marbles selected is not equal to the total number of green marbles selected, then there was a mistake in selecting the marbles or recording the data.

Theoretically, the probability of selecting one red marble from this bag is 0.20.
If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student.
What are the probabilities?Probability determines how likely it is an event would happen. The chances of the event happening lie between 0 and 1.
The probability of selecting one red marble from this bag = number of red marbles / total number of marbles

Complete the table for the given rule.
Rule:y= 4/1 x+1y
Answer: 2, 3, 4
Step-by-step explanation:
In the table graph provided, you will a column that has "x" as it's title. Under x, 4, 8, and 12 should listed. You figure out the answers for y by inputting the x value into the rule: y = 1/4x + 1.
For y = 1/4(4) + 1, you would multiply 1/4 by 4 and since the fours eliminate one another, you would get 1. Now, you would do 1 + 1, which equals 2. For y = 1/4(8) + 1, you would multiply 1/4 by 8 and since four and eight share the number four as their greatest common factor, four would be eliminated and eight would be reduced to 2. Now, you would do 2 + 1, which equals 3.For y = 1/4(12) + 1, you would multiply 1/4 by 12 and since four and twelve share the number four as their greatest common factor, four would be eliminated and twelve would be reduced to 3. Now, you would do 3 + 1, which equals 4.
