Chandra wishes to reduce has mass by 6% in a month's time if his mass is 80 kg now what should his mass in a month's time Be?

Arturiano [62]

Answer:

75.2 kg

Step-by-step explanation:

His mass now is 80 kg which is 100% of his mass since 100% is the entire amount. He wishes to reduce his mass by 6%.

100% - 6% = 94%

After reducing his mass by 6%, his mass will become 94% of his original mass, 80 kg.

We need to find 94% of 80 kg.

94% of 80 kg = 94% × 80 kg = 0.94 × 80 kg = 75.2 kg

Help me do the ones marked in red.

Dmitrij [34]

Answer:

2. "two thirds of the fourth power of r"

4. n + 14

6. 7 +11n

8. (2/5)n^2

7. 28

8. 1/5

Step-by-step explanation:

2. "two thirds of the fourth power of r"

4. "sum" means the listed items are added. You can use any convenient variable to represent "a number." I often use n for number.

n + 14

6. "7 more than" means 7 is added to whatever follows. "11 times a number" means the number is multiplied by 11.

7 + 11n

8. "of" means "times". The square of a number is that number to the power of 2.

(2/5)n^2

7 & 8 (evaluation). Your calculator can do this. (If not, get one that can.) Note that parentheses are needed around numerators and denominators and anything else that must be treated as a single value.

Zarrin [17]

Answer:

10+2x

Step-by-step explanation:

A rectangle has 4 sides. Two pairs of sides are congruent.

For example a rectangle could have sides of 6, 10, 6, and 10.

So the perimeter would be the sum of those sides, 6+6+10+10.

6+6+10+10 can be written like 2(6)+2(10)

For the rectangle in your question it would be 5+5+x+x, which can be written like 2(5)+2(x)

Simplify to 10+2x.

siniylev [52]

Answer:

T = 3.5 hours

Step-by-step explanation:

this is a rate problem.

an experienced surveyor takes 7 hours to survey a roadbed

an apprentice surveyor takes 9 hours to survey a roadbed

the rate of the experienced surveyor = $\frac{1}{7}$

the rate of the apprentice surveyor = $\frac{1}{9}$

if the two work together , $\frac{1}{T} =\frac{1}{7} +\frac{1}{9}$

T = $\frac{56}{16}$

T = 3.5 hours
