The minute hand of a watch has a length of 1.4 cm. Find the; (a) distance moved by the tip of the minute hand from 8.13 am to 8.

LenKa [72]

Answer:

A). The distance covered= 5.2752 cm

B). Angle swept = 36°

C). The time = 8:45 am

Step-by-step explanation:

The watch is assumed to be a circle while the minute hand is assumed to be the radius

Radius = 1.4cm

A). From 8:13 to 8:49= 36 minutes

Recall, there is 60 minutes in a round watch.

The distance covered= 2πr*36/60

The distance covered= 2*3.14*1.4*0.6

The distance covered= 5.2752 cm

B). If distance covered is 8.8 mm

8.8 mm = 0.88cm

0.88= 2*3.14*1.4*(x/360)

0.88/(8.792)=x/360

0.1= x/360

36°= x

Angle swept = 36°

C). The time it will be if the watch started from 8:39 am and moved 36°

36/360= y/60

0.1= y/60

0.1*60= y

6 minutes= y

The time with be 8:39+6 minutes

The time = 8:45 am

A company makes two types of biscuits: Jumbo and Regular. The oven can cook at most 400 biscuits per day. Each jumbo biscuit re

xz_007 [3.2K]

Answer:

$ 44

Step-by-step explanation:

If we analyze the statement well, we can observe something very crucial to solve it, the jumbo biscuits require 2 oz of flour and give a profit of $ 0.08, the Regular one that only requires 1 oz of flour leaves a profit of $ 0.11, which means that requiring a smaller quantity of flour leaves a greater profit, so in terms of profit it is not profitable to make Jumbo, only Regular.

Therefore, since you can make 400 biscuits, they would all be regular since there are 600 oz of flour available, it is enough to make 400, therefore the maximum profit would be:

$ 0.11 * 400 = 44

The maximum possible profit is $ 44

Matthew has two kind of rice brown rice 8 7/8 and white rice 6 3/4 How much more brown rice than white rice does Matthew have?

pychu [463]

Mathew has $\frac{17}{8} \text{ or } 2\frac{1}{8}$ more brown rice than white rice

Solution:

Given that Matthew has two kind of rice ; brown rice and white rice

From given question,

$\text{Brown rice } = 8\frac{7}{8}\\\\\text{White rice } = 6\frac{3}{4}$

Let us convert the mixed fractions to improper fractions

Multiply the whole number part by the fraction's denominator

Add that to the numerator

Then write the result on top of the denominator

$\text{Brown rice } = 8\frac{7}{8} = \frac{8 \times 8 + 7}{8} = \frac{71}{8}$

$\text{White rice } = 6\frac{3}{4} = \frac{4 \times 6 + 3}{4} = \frac{27}{4}$

How much more brown rice than white rice does Matthew have?

So we need to find the difference between brown rice and white rice

Difference = brown rice - white rice

$difference = \frac{71}{8} - \frac{27}{4}$

Make the denominators same for easier calculations

$difference = \frac{71}{8} - \frac{27 \times 2}{4 \times 2}\\\\difference = \frac{71}{8} - \frac{54}{8}\\\\difference = \frac{71 - 54}{8} = \frac{17}{8}$

Converting again to mixed fractions we get,

$difference = \frac{17}{8} = 2\frac{1}{8}$

Thus Mathew has $\frac{17}{8} \text{ or } 2\frac{1}{8}$ more brown rice than white rice
