Answer 1

Answer: [tex]11\dfrac{1}{8}[/tex] or 11.125

Step-by-step explanation:

[tex]10+(2 \times 3)^{2} \div 4 \times \bigg (\dfrac{1}{2} \bigg )^{3}=10+6^{2} \div 4 \times \dfrac{1}{8}=10+36 \div 4 \times \dfrac{1}{8}= \\\\ =10+9 \times \dfrac{1}{8}=10+\dfrac{9}{8} =10+1\dfrac{1}{8} =11\dfrac{1}{8} =11.125[/tex]

Answer 2

Answer:

10 + (2 x 3) {2} divided by 4 x (1/2) {3} = 2.375 (2  3/8)

Step-by-step explanation:

2 x 3 is 6 and 6 to the power of 2 is 36, and PEMDAS makes it where you divided 36 by four instead of 46 (10 + 36) divided by 4. 36 divided by 4 = 9. 10 + 9 = 19. Then 1/2 to the third power is 1/8. 19 times 1/8 = 2.375 (2  3/8)

Mr. Sonny's science class is calculating the average number of blinks per minute. Jan blinks 126 times in 7 minutes. What is her blinking rate, in blinks per minute?

Answers

18 blinks per min since 126 divided by 7 equals 18
Answer:
b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.

The change in altitude of a bird after 2 __ 1 2 seconds was –41 __ 1 4 feet. What was the average change in altitude of the bird in feet per second?

Answers

Answer:

[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]

Step-by-step explanation:

Given

[tex]Altitude\ Change = -4\frac{1}{4} \ ft[/tex]

[tex]Time = 2\frac{1}{2}\ s[/tex]

Required

Determine the average change

This is calculated as follows:

[tex]Average\ Change = \frac{Altitude\ Change}{Time}[/tex]

This gives:

[tex]Average\ Change = \frac{-4\frac{1}{4}}{2\frac{1}{2}}[/tex]

[tex]Average\ Change = -4\frac{1}{4}/2\frac{1}{2}[/tex]

Convert to improper fractions

[tex]Average\ Change = -\frac{17}{4}/\frac{5}{2}[/tex]

Convert to multiplication

[tex]Average\ Change = -\frac{17}{4}*\frac{2}{5}[/tex]

[tex]Average\ Change = -\frac{17}{2}*\frac{1}{5}[/tex]

[tex]Average\ Change = -\frac{17}{10}[/tex]

[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]

A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $10 million after 4 years, as shown in the graph:

There is a graph of a line with Years on the x axis and Profits in millions on the y axis that passes through 0, negative 20 and 4, 10.

Which equation most closely represents the line depicted in the graph?

f(x) = −10x + 4
f of x equals fifteen halves times x minus 20
f(x) = 10x − 4
f of x equals two fifteenths times x minus 20

~5 points
~164 ducks
~225 ducks
~246 ducks
In the above question, what was the original amount of ducks?
~205
~20
~246
~164

Answers

Answer:

246

Step-by-step explanation:

246. Step 1) Calculate 20 percent of 205: To calculate 20 percent of 205, you multiply 20 by 205 and then divide the product you get by 100. Here is the math to illustrate:

20 x 205 = 4100
4100 / 100 = 41

Step 2) Add the 20 percent you calculated in Step 1 to 205. Here is the math to illustrate:

205 + 41 = 246

Therefore, the answer to "What is 205 plus 20 percent?" is:
