In parallelogram DEFG if m_DEF=110° find m_FGD.
E
110°
D
G
Answer:
E=x
or 110= x ( opposite angles of parallelogram are congurent)
E+D = 180 ( angles on st line)
110+D =180
D=70
D=F ( opposite angles of parallelogram are congurent)
so F=70

What is the simplified form of
72x16/50x36 ? assume x ≠ 0
Answer:
Option A
Step-by-step explanation:
[tex]\sqrt{\frac{72x^{16} }{50x^{36} } } = \sqrt{\frac{36x^{16} }{25x^{36} } } = \frac{\sqrt{36x^{16} } }{\sqrt{25x^{36} } } = \frac{\sqrt{36} \times \sqrt{x^{16} } }{\sqrt{25} \times \sqrt{x^{36} } } = \frac{6x^{8} }{5x^{18} } = \frac{6}{5} \times x^{8-18} =\frac{6}{5} \times x^{-10} = \frac{6}{5x^{10} }[/tex]
The ratio of red to blue marbles in a bag is 3:2. If there are 20 total marbles in the bag, how many blue marbles are in the bag?
Answer:
8
Step-by-step explanation:
Let's say there are 3*x red marbles in the bag. As the ratio of red to blue is 3:2, that means that there are 2*x blue marbles in the bag. The total marbles are then
3*x+2*x= 20
= 5x
Divide both sides by 5 to get
x=4
2*x is the amount of blue marbles, and 2*x = 8

the lowest number is 3 and the highest is 9 so 9-3 = 6 so for this example the answer is 6.
Find the value of x.
4x + 5
2x + 21, smby help me wit dis pls
Answer: x = 8
Step-by-step explanation:
4x + 5 = 2x + 21
4x + 5 - 2x = -2x + 2x +21 (Subtract 2x from both sides)
2x + 5 = 21
2x + 5 - 5 = 21 - 5 (Subtract 5 from both sides)
2x = 16
2x/2 = 16/2 (Divide both sides by 2)
x = 8

what is the domain of h?
Answer:
The domain of given function is: [-7,7]
Step-by-step explanation:
Graphs can be used to determine the domain and range of a function.
On a graph, the values across the x-axis are domain and across y-axis are the range.
In the given graph, we can see that the graph starts from x=-7 and ends at x=7. The filled circle at both ends of the graph indicate that the values 7 and -7 are also included in the domain.
Hence,
The domain of given function is: [-7,7]
Write this multiplication expression using an exponent: 2 . 2 . 2 = ?
Answer:2^3
Step-by-step explanation:
can someone help with this question?
Find the value of x. Then find the measure of each angle.
1. x =
2. Angle =
3. Angle =
1. x+(x-26)= 180 (being corresponding angle)
2x-26=180
2x=180-26
2x=154
x=154÷ 2
∴x=77

9514 1404 393
Answer:
a) see attachment
b) base: 4, height: 4√3
c) area: 16√3
Step-by-step explanation:
a) The figure is drawn in the attachment
__
b) The side lengths of a 30-60-90 right triangle have the ratio ...
1 : √3 : 2
Multiplying these by 4 gives the side lengths of each triangle created by the diagonal. The base (short leg) is 4 units; the height (long leg) is 4√3 units.
__
c) The area is the product of base and height:
A = bh
A = 4(4√3) = 16√3 . . . . square units

Find the total surface area of this triangular prism.
height=24cm
width=14cm
length=10cm
slant height=25cm
If the picture below is the triangular prism
Answer:
976
Step-by-step explanation:
14 x 24 = 336 [It's a triangle you would half it but then as there are 2 you would keep it the same]
10 x 25 = 250 [Times by 2 because there are 2 of them]
10 x 14 = 140
336 + 250 + 250 + 140 = 976
Pam walks 7/8 of a mile to school. Paul walks 1/2 of a mile to school. How much
farther does Pam walk than Paul?

Simplify 5(x - 2) - 3x + 7.
A. 8x - 3
B. -10x + 25
C. 2x-5
D. 2x - 3
2x-3
Step-by-step explanation:
5(x-2) is 5x-10 then add the -3x + 7, add 5x and -3x to get 2x then add -10 and 7 and get 3 so its gonna be D. 2x-3
Answer:
D. 2x - 3
Step-by-step explanation:
5(x - 2) - 3x + 7 = 5 · x - 5 · 2 - 3x + 7 = 5x - 10 - 3x + 7 = 2x - 3

What is the total area of the shaded region? Type just the answer in the blank.
Answer:
240cm
Step-by-step explanation:
6cm*14cm= 84cm
6*6=36
84+36=120*2=240
Answer:
7cm x 8cm
Step-by-step explanation:
The 14cm x 12cm box (top 'box 1') intersects with the 14cm x 12cm box (bottom 'box 2').
Half the values of each side are subtracted from one another, so
horizontal length: 14/2 = 7cm
vertical length: 12/2 = 6cm
Box 2 horizontal length (total) = 14cm devided by half the length of box 1 (7cm)
14 - 7 = 7cm
Box 2 vertical length (total) = 12cm devided by half the length of box 1 (6cm)
12 - 6 = 6cm
The total area is calculated by multiplying the horizontal and vertical lengths
7x6 = 42
the answer is 42
