1 answer:

7 0

Part A.
7.8 is a rational number between 7.7 and 7.9.
It is rational because it can be written as a fraction of integers, such as 78/10.

Part B.
sqrt(60) = 7.75
sqrt(60) cannot be written as a fraction of integers. It is a decimal number that never ends and never repeats.

The angles of a triangle are in the ratio 11 : 5 : 2. The side opposite the largest angle is 5.5 centimeters. The length of the

beks73 [17]

The side opposite the lasrgest angle will also be the largest side in the triangle

Here it s 5.5 cms.

so using the given ratios we have

2/11 = x /5.5 where x is the smallest side (opposite the smallest angle)

x = (2*5.5) / 11 = 1 cm.

Initially, there were only 197 weeds at a park. The weeds grew at a rate of 25% each week. The following function represents the

Anarel [89]

Answer:

D.) f(x) = 197(1.03)^(7x); grows at a rate of approximately 3% daily

Step-by-step explanation:

The growth equation can be written in terms of a rate compounded 7 times per week:

f(x) = 197×1.25^x = 197×(1.25^(1/7))^(7x)

f(x) ≈ 197×1.0324^(7x) . . . . x represents weeks, a daily growth factor is shown

The daily growth rate as a percentage is the difference between the daily growth factor and 1, expressed as a percentage:

(1.0324 -1) × 100% = 3.24%

The best match is choice D:

f(x) ≈ 197(1.03^(7x)); grows approximately 3% daily

Liliana used 444 dark power crystals to raise 141414 zombie soldiers. She wants to know how many zombie soldiers (z)(z)left pare

Mariulka [41]

Question is bit incorrect, Correct question is given below.

Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) she can raise with 10 dark power crystals. How many zombie soldiers can Liliana raise with 10 power crystals?

Answer:

Liliana can raise 35 zombie soldiers.

Step-by-step explanation:

Let the number of zombie soldiers raised by 10 dark power crystals be 'z'.

Zombie raised by 4 power crystals = 14

Since the number of zombie and power crystals are in direct proportion.

Therefore, we get

$\frac{z}{10}=\frac{14}{4}$

Multiply 10 on both the sides, we get

$z=\frac{14}{4}\times 10 = 35$

Hence, Liliana can raise 35 zombie soldiers.
