Triangle DEF is on a coordinate plane with its
vertices located at D( – 3,5), E( – 3, - 2), and
F(3,0). What is the area of ADEF in square
units?
Answer:
[tex]21\ \text{square units}[/tex]
Step-by-step explanation:
The points are [tex]D(-3,5), E(-3,-2)[/tex] and [tex]F(3,0)[/tex].
Area of a triangle is given by
[tex]A=\dfrac{D_x(E_y-F_y)+E_x(F_y-D_y)+F_x(D_y-E_y)}{2}[/tex]
[tex]\Rightarrow A=\dfrac{-3(-2-0)+-3(0-5)+3(5-(-2))}{2}[/tex]
[tex]\Rightarrow A=21\ \text{square units}[/tex]
The area of the given triangle is [tex]21\ \text{square units}[/tex].

Answer:
4 8.95h + 10 < 115
Step-by-step explanation:
Answer: 4) 8.95h + 10 < 115
Step-by-step explanation:
We know the inequality will be equal to less than 115 since it states that the order was less than $115.
The equation would look like: some amount of shin guards times 8.95 each + $10 shipping = less than $115
8.95h + 10 < 115
(h in the given equation is the amount of shin guards)

"The difference between the circumference and diameter of a wheel is 18cm. Find the radius of the wheel. Use 3.14 for Pi. Round to the nearest tenth."
Answer:
[tex]4.2\ \text{cm}[/tex]
Step-by-step explanation:
d = Diameter of wheel
The difference between the circumference and diameter of a wheel is 18 cm.
[tex]2\pi r-d=18\\\Rightarrow \pi d-d=18\\\Rightarrow d(\pi-1)=18\\\Rightarrow d=\dfrac{18}{\pi -1}\\\Rightarrow d=\dfrac{18}{3.14-1}\\\Rightarrow d=8.41\ \text{cm}[/tex]
The diameter of the wheel is 8.41 cm so the radius will be [tex]\dfrac{8.41}{2}=4.205\approx 4.2\ \text{cm}[/tex].

How many degrees is angle A?
Answer:
128 degrees
Step-by-step explanation:
Answer: 112 degrees
============================================================
Explanation:
If we assume ABCD is a parallelogram, then the adjacent angles are supplementary.
So,
A+D = 180
A+68 = 180
A = 180-68
A = 112

Answer:
1) x = 71
2) x = 117
5)
m<1: 35
m<2: 77
m<3: 52
m<4: 77
m<5: 65
m<6: 25
Step-by-step explanation:
1)
x + 41 + 68 = 180
x + 109 = 180
x = 71
2)
x + 47 + 16 = 180
x + 63 = 180
x = 117
3)
<2 + 103 = 180
<2 = 77
<1 + 68 + 77 = 180
<1 + 145 = 180
<1 = 35
<4 + 103 = 180
<4 = 77
<5 + 41 + 77 = 180
<5 + 115 = 180
<5 = 65
<6 + 65 = 90
<6 = 25
<3 + 103 + 25 = 180
<3 + 128 = 180
<3 = 52
2x + 3 = -x + 12
Solve the equation, explanation is good.
Answer:
3
Step-by-step explanation:
2x + 3 = -x + 12
subtract 3 from both sides
2x = - x + 9
add x to both sides
3x = 9
divide by 3
x = 3
Can someone Help? thank you! :)
Answer:
$3
Step-by-step explanation:
Since he’s leaving a 20% tip, we need 20% of 15.
To solve, multiply 20/100 (20%) by 15:
20/100*15 = 300/100 = 3
He will leave a $3 tip.
Answer:
$3
Step-by-step explanation:
To solve this problem, first, one must convert the percent of the tip to decimal form. This can be done by dividing the percent by 100. Then one will multiply this value by the total bill.
20% * 15
= 0.2 * 15
= 3

A number x is no more than - 8
Answer:
x ≤ -8
Step-by-step explanation:
"A number x": x
"is no more than": ≤*
"-8": -8
x ≤ -8 is your answer.
*Note the choice of less than or equal too. "No more than" implies that it can technically be -8, only that it can't be greater than -8 (-7 or more).

Segment MP is a diameter of circle O.
Circle O is shown. Line segment M P is a diameter. Line segment N O is a radius. Angle N O P is 150 degrees.
Which equation can be used to find mArc M N?
mArc M N – 150 = 360
Answer:
[tex]arc\ MN + 150 = 180[/tex]
Step-by-step explanation:
Given
[tex]\angle NOP = 150^\circ[/tex]
See attachment for circle O
Required
Find [tex]arc\ MN[/tex]
The sum of angles in a semi-circle is 180 degrees.
So:
[tex]arc\ MN + \angle NOP = 180[/tex]
This gives:
[tex]arc\ MN + 150 = 180[/tex]
Hence, the equation is: [tex]arc\ MN + 150 = 180[/tex]
