I think it’s true not 100 percent sure tho
You add 3 1/2 to 2 1/7 to get the tallest skeleton.
3 1/2 = 7/2 and 2 1/7= 15/7
First you find common denominators for both fractions. 2 and 7 go into 14.
2 times 7 equals 14
7/2 * 7 = 49/14
7 times 2 equals 14
15/7 * 2 = 30/14
49/14 + 30/14= 79/14
then you simplify 79/14.... 14*5= 70 and 9 are left over. 5 9/14
The number pi is a constant, it's the ratio of a circles circumference to it's diameter.
Answer:
See below.
Step-by-step explanation:
The square root of a number is a number than when multiplied by itself, you get the original number.
For example, the square root of 4 is 2 since 2 * 2 = 4, but the square root of 4 is also -2 since (-2) * (-2) = 4. Since the product of 2 negative numbers is positive, and the product of two positive numbers is also positive, each positive integer has two square roots, one positive and one negative.
The cubic root of a number is a number that when you cube you get the original number. To cube a number, you must find the product of 3 equal numbers. For example, the cubic root of 8 is 2 since 2 * 2 * 2 = 8. The cubic root of 8 cannot be -2 since (-2) * (-2) * (-2) = -8, not 8. When you multiply 3 positive numbers together, the product is positive. When you multiply three negative numbers together, the product is negative. Because of this, a positive number has a positive cubic root, and a negative number has a negative cubic root. A positive integer has only one cubic root.
Answer: Using the proportion beteween the sides of the similar triangles, the distance between the endpoints of the beams P and Q is 3.2 inches.
Option a. 3.2 inches
Solution
PR=3.7 inches; CR=5.6 inches; AC=4.9 inches
As the two triangles QRP and ARC are similar, their sides must be proportionals, then:
PQ/AC=PR/CR=QR/AR
Replacing the given values in the proportion above:
PQ/(4.9 inches)=(3.7 inches)/(5.6 inches)=QR/AR
PQ/(4.9 inches)=3.7/5.6
Solving for PQ: Multiplying both sides of the equation by 4.9 inches:
(4.9 inches)[PQ/(4.9 inches)]=(4.9 inches)(3.7/5.6)
PQ=(4.9)(3.7)/5.6 inches
PQ=18.13/5.6 inches
PQ=3.2375 inches
Rounding to one decimal place:
PQ=3.2 inches
