Answer:
1/a^8/5 for the first, 9b^8/3 for the second, and 8x^25/7 for the third
Step-by-step explanation:
1) With neg exponents, you can just take it and flip it, and make the exp pos i.e. 1/a^8/5
2) When there is an exponent outside of parenthesis of a number with an exponent, you multiply the exponents together i.e. 9b^8/3
3) The same applies to this as the 2nd, we just multiply to get 8x^25/7
What is the value of x in the equation 3(2x + 4) = −6? (4 points)
a
−3
b
1
c
12
d
19
Answer:
x = - 3
Step-by-step explanation:
Given
3(2x + 4) = - 6 ( divide both sides by 3 )
2x + 4 = - 2 ( subtract 4 from both sides )
2x = - 6 ( divide both sides by 2 )
x = - 3
can someone please help me, ill give brainliest plus points!
Answer:
9 is the correct answer all the best
Step-by-step explanation:
(x + 0.5)/6 = 19/12
2(x + 0.5) = 19 (multiply 12 on both sides)
x + 0.5 = 9.5 (divide 2 on both sides)
x = 9 (subtract 0.5 on both sides)
The answer is 9.

A box of an area covers four feet if the height of the box if 3 feet what is the volume of the box?
Answer:
12 cubic ft.
Step-by-step explanation:
A=bh=4(3)=12 ft^3
Answer:
12 ft ^3
Step-by-step explanation:
Volume of the box would be width x length x height
If the box of an area already covers four feet (width times length) we just need to multiply by the height:
4*3 =12 cubic feet
Hope this helps! :)

Physical therapists measure strength on a dynamometer, which uses a unit called a foot-pound. Suppose you increase the strength in your elbow joint from 90 foot-pounds to 125 foot-pounds. Find the percent of increase to the nearest percent.
A.
39%
B.
138.9%
C.
28%
Answer:
A. 39%
Step-by-step explanation:
(125-90)/(90)=(35)/(90)=0.3889 or 39%
To find the percent increase, we need to divide the amount of change by the original amount.
if a rectangle has the area of 21 square units, what is the perimeter
A scientist measures the change in the temperature of a chemical solution. At the start of the experiment, the solution is at a temperature of -14.96ºC. The temperature decreases 2.9ºC each hour. 1️⃣ Find the temperature of the solution after 3 hours. 2️⃣ Find the temperature of the estimated solution after 3 hours.
Answer:
-6.26°C
Step-by-step explanation:
Given that:
Initial temperature = - 14.96ºC
Temperature change per hour = 2.9ºC
Hence, the temperature of the solution after 3 hours can be obtained thus :
Final temperature = (initial temperature + (temperature change per hour * Number of hours))
Temperature after 3 hours :
-14.96 + 2.9(3)
-14.96 + 8.7
= - 6.26

Compute $\sqrt{64} + \sqrt{225} - \sqrt{64 + 225}$.
Answer:
6
Step-by-step explanation:
Simplify the following:
sqrt(64) + sqrt(225) - sqrt(64 + 225)
Hint: | Evaluate 64 + 225.
64 + 225 = 289:
sqrt(64) + sqrt(225) - sqrt(289)
Hint: | Simplify radicals.
sqrt(289) = sqrt(17^2) = 17:
sqrt(64) + sqrt(225) - 17
Hint: | Simplify radicals.
sqrt(64) = sqrt(2^6) = 2^3:
2^3 + sqrt(225) - 17
Hint: | In order to evaluate 2^3 express 2^3 as 2×2^2.
2^3 = 2×2^2:
2×2^2 + sqrt(225) - 17
Hint: | Evaluate 2^2.
2^2 = 4:
2×4 + sqrt(225) - 17
Hint: | Multiply 2 and 4 together.
2×4 = 8:
8 + sqrt(225) - 17
Hint: | Simplify radicals.
sqrt(225) = sqrt(15^2) = 15:
8 + 15 - 17
Hint: | Evaluate 8 + 15 - 17.
8 + 15 - 17 = 6:

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is amperes when the resistance is ohms. What is the current when the resistance is ohms?
Answer:
[tex]\mathbf{I = 0.22 \ amperes}[/tex]
Step-by-step explanation:
From above:
let assume that;
The current is [tex]\dfrac{1}{2}[/tex] ampere when resistance is 240 ohms.
Now, to find the current when R = 540 ohms.
SO; if [tex]I \ \alpha \ \dfrac{1}{R}[/tex]
[tex]I \ =\ \dfrac{k}{R}[/tex] where k = constant
[tex]\dfrac{1}{2} \ =\ \dfrac{k}{240}[/tex]
[tex]2k = 240[/tex]
[tex]k = \dfrac{240}{2}[/tex]
[tex]k = 120[/tex]
Thus; the constant = 120
So; when R = 540 ohms
then the current will be:
[tex]I = \dfrac{k}{R}[/tex]
[tex]I = \dfrac{120}{540}[/tex]
[tex]\mathbf{I = 0.22 \ amperes}[/tex]

Una milla terrestre mide 1,609 km y una milla náutica mide 1,852 km. ¿ Cuántos metros más mide la milla náutica ?
Answer:
The mile is an English unit of length of linear measure equal to 5,280 feet, or 1,760 yards, and standardised as exactly 1,609.344 metres by international agreement in 1959. With qualifiers, "mile" is also used to describe or translate a wide range of units derived from or roughly equivalent to the Roman mile, such as the nautical mile (now 1.852 km exactly), the Italian mile (roughly 1.852 km), and the Chinese mile (now 500 m exactly). The Romans divided their mile into 5,000 Roman feet but the greater importance of furlongs in pre-modern England meant that the statute mile was made equivalent to 8 furlongs or 5,280 feet in 1593. This form of the mile then spread to the British-colonized nations some of which continue to employ the mile. The US Geological Survey now employs the metre for official purposes but legacy data from its 1927 geodetic datum has meant that a separate US survey mile (6336/3937 km) continues to see some use. While most countries replaced the mile with the kilometre when switching to the International System of Units, the international mile continues to be used in some countries, such as Liberia, the United Kingdom, the United States, and a number of countries with fewer than one million inhabitants, most of which are UK or US territories, or have close historical ties with the UK or US.
