Answer: 212.5%
Step-by-step explanation: To convert to a percent, we will first need to change to an improper fraction. To write a mixed number as an improper fraction, first multiply the denominator by the whole number and then add the numerator.
8 x 2 = 16
16 + 1 = 17
original denominator = 8.
Improper fraction →
Now, to convert a fraction to a percent, first remember that a percent is a ratio of a number to 100. If we want to convert 17/8 to a percent, we need to find a fraction equivalent to 17/8 that has a 100 in the denominator. We can do this by setting up a proportion.
Now, we can use cross products to find the missing value.
8n = 1700
÷8 ÷8 ← divide both sides by 8
n = 212.5
Therefore, 2 and 1/8 is equivalent to 212.5%.
Answer: B = 70°, b = 29.2; c = 29.2
Step-by-step explanation:
sum of angles in a triangle is 180
40+70 +X = 180
X is the last angle
110+x=180
x= 180-110 =70
A= 40°
B= 70°
C= 70°
the triangle is Isosceles triangle meaning two sides are equal , angle B = angle C
Answer:
8/9 (simplified)
Step-by-step explanation:
Total marbles = 18
Total of marbles <em>not</em> white = 16
Numerator = 16 / Denominator = 18
= 16/18
= 8/9 (simplified)
Answer:
x=144
Step-by-step explanation:
We got x and x/4 right
If you put x on the same line as x/4, you gon see that x+x/4=180
Then, just do your algebra and get x=144
