Answer:

44.6

Step-by-step explanation:

Since the sides with the two tick marks are equal to 7.4, and there are three of these sides, they are equal to 7.4 times 3, which is 22.2. The remaining sides have 1 tick, meaning they are 11.2, meaning this is 11.2 * 2, which is 22.4. The combined perimeter is 44.6 cm.

Explain how a points distance from 0 relates to the value of the number that it represents

Gnoma [55]

Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative. Take a look at some examples. The distance from 5 to 0 is 5 units.

An owner of an repair service Company eliminates that for every 30 hours a repair person is on the job he can bill for only 72%

vredina [299]

Answer: He is idle for 8.4 hours.

Step-by-step explanation:

Since we have given that

Number of hours he repairs =30 hours

Percentage of hours he worked = 72%

Remaining percentage of hours he remains idle is given by

$100-72\\\\=28\%$

So, Number of hours he is idle for a driving is given by

$0.28\times 30\\\\=8.4\ hours$

Hence, he is idle for 8.4 hours.

Solve for x:<br> 2 = 4(x - 5) + 4x

vova2212 [387]

Answer:

2.75

$2 = 4(x - 5) + 4x \\ 2 = 4x - 20 + 4x \\ 2 = 8x - 20 \\ 2 + 20 = 8x \\ 22 = 8x \\ \frac{22}{8} = x = 2.75$

To help answer this question, Deigo wrote the division equation 3/4 divided by 2/5. Explain why this equation does not represent

Mars2501 [29]

Answer:

The fraction of the rain filled in the gauge will be = $\frac{8}{15}$

Diego wrote the division equation incorrectly.

It must be given as $\frac{2}{5}$ divided by $\frac{3}{4}$ .

Step-by-step explanation:

Given:

After $\frac{3}{4}$ of an hour of rain the rain gauge is $\frac{2}{5}$ filed.

To find the fraction of the rain that will be filled in the gauge if it continues to rain at the same rate for 15 more minutes.

Solution:

15 minutes in hours will be = $15\ min \times \frac{1\ hour}{60\ min}$ = $\frac{1}{4}$ of an hour.

Given that it has rained for $\frac{3}{4}$ of an hour, and it continues to rain for $\frac{1}{4}$ of an hour more.

Thus, total time of rain will be = $\frac{3}{4}+\frac{1}{4}=\frac{4}{4}=1\ hour$

Using unitary method to find the fraction of rain filled in the gauge after 1 hour of rain.

If in $\frac{3}{4}$ of an hour of rain the rain gauge is $\frac{2}{5}$ filed.

Thus, in 1 hour of rain the gauge will be filled by = $\frac{2}{5}\div \frac{3}{4}$

To divide fractions, we take reciprocal of the divisor and replace division by multiplication.

⇒ $\frac{2}{5}\times\frac{4}{3}$

⇒ $\frac{8}{15}$

Thus, the fraction of the rain filled in the gauge will be = $\frac{8}{15}$

Diego wrote the division equation incorrectly.

It must be given as $\frac{2}{5}$ divided by $\frac{3}{4}$ .
