300
Step-by-step explanation:
17/100x=51
x=300
17/100(300)=51
Answer:
length of BC = 5 1/4 feet
Step-by-step explanation:
Area of a triangle = 1/2×base×height
Area = 4 3/8 square feet
Base = AC= 1 2/3 feet
Height = BC = ?
Area of a triangle = 1/2×base×height
4 3/8 = 1/2 × 1 2/3 × height
35/8 = 1/2 × 5/3 × height
35/8 = 5/6 × height
Height = 35/8 ÷ 5/6
= 35/8 × 6/5
= (35 × 6) / (8 × 5)
= 210 / 40
= 5 1/4 feet
Height = BC = 5 1/4 feet
length of BC = 5 1/4 feet
Answer:
46.5
Step-by-step explanation:
Of all straight angles have 180 degrees in them.
So, to find x we need to form this equation:
x + 65 + x - 22 = 180
2x + 43 = 180
2x = 180-43
2x = 137
68.5 degrees = x
68.5-22 = 46.5 degrees.
m<CBD = 46.5 degrees.
m<GBF = also 46.5 degrees because it is a vertical angle to <46.5 degrees.
Yea they are cuz they have the same side and angle measurements
based on the number of marbles in the bag, the number of marble groups possible is 7,140 groups.
the probability of selecting 2 red and 1 yellow is 1/68.
<h3>what number of 3-marble groups can be made?</h3>
first, find the number of marbles:
= 7 + 8 + 9 + 7 + 5
= 36
the number of marble groups are:
= 36 ! / (3 ! x 33 !)
= 7,140 groups
the probability of picking 2 red and 1 yellow is:
= (( (7! / (2! x 5!)) x ( ( 5! / (1! x 4!))) / 7,140
= 1 / 68
= 1.47%
