Answer:
36
Step-by-step explanation:
You multiply top and bottom of the fraction by the conjugate of 5 - √2 which is 5 + √2. This produces a rational denominator:-
= √7 ( 5 + √2) / (5 - √2)(5 + √2)
= √7 ( 5 + √2) / (25 -2)
= (√7 ( 5 + √2)) / 23 answer
Answer:
14.24 foot far is the mirror from the base of the statue.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
As per the statement:
See the diagram as shown below:
Height of a boy = 5.9 foot tall
Height of a statue = 12 foot.
Distance of a boy from the mirror = 7 feet.
Let x be the distance of the mirror from the base of the statue.
then by definition of proportion we have;
Substitute the given values we have;
By cross multiply we have;
Divide both sides by 5.9 we have;
x = 14.24 ft
Therefore, 14.24 foot far is the mirror from the base of the statue.
Answer:
2750 milliliters
Step-by-step explanation:
Let's start by changing the unit of measurement from liters (L) to milliliters (mL), since milliliters is the form in which you are giving your answer. Doing this tells us Lamar drinks 550 mL of milk every day. Since you need to find out how much milk he drinks in 5 days, just multiply the first answer by 5, so 550 x 5. This gives us 2750 mL.
Answer:
Division and multiplication are inverse operations. This means they "undo" each other. You can check your answer by multiplying the quotient by the divisor. You should get the dividend.
have a great day :)
