Answer:
x = 2
Step-by-step explanation:
Note that 25 = 5² , then
[tex]5^{(6-2x)}[/tex] = 5²
Since the bases on both sides are 5 then equate the exponents
6 - 2x = 2 ( subtract 6 from both sides )
- 2x = - 4 ( divide both sides by - 2 )
x = 2
Laurie is trying to stay within 10 feet of her current diving depth of -30 feet (with regard to sea level) so that the light is still good but she can be close to the sea life during her scuba dive Which two equations can be used to find the minimum and maximum depths Laurie wants to stay between?
Answer:
It should be the first one
Step-by-step explanation:
since positive ten would represent going further up and negative ten going further down, the diver would be within ten feet of her current position
Answer:
A) -30 - x = 10 and -30 - x = –10
Step-by-step explanation:
Part 1:
1) Isolate the variable x
-30 - x = 10
-x = 40
2) Multiply both sides by -1
x = -40
Therefore -30 - x = 10 is correct
Part 2:
1) Isolate the variable x
-30 - x = –10
-x = 20
2) Multiply both sides by -1
x = -20
Therefore -30 - x = –10 is also correct
Final Answer: -30 - x = 10 and -30 - x = –10

Help please. It’s geometry and it asks to find the shaded region.
Answer: (a)
Step-by-step explanation:
Given
The diameter of the inner circle is [tex]d=14\ m[/tex]
thickness of the strip is [tex]t=2\ m[/tex]
So, the radius of inner circle is [tex]r=7\ m[/tex]
Radius of the outer circle [tex]R=7+2=9\ m[/tex]
Area of the shaded region is the difference of the area of outer circle and inner circle.
[tex]\Rightarrow \pi R^2-\pi r^2\\\Rightarrow \pi (9^2-7^2)\\\Rightarrow 3.142\times 32\\\Rightarrow 100.5\ m^2[/tex]
hence, option (a) is correct.
The temperature in Greenland was -12°. For 4
hours the temperature rose 3º every hour.
What was the temperature after 4 hours?
Please help me with this math problem
Using proportions, it is found that the temperature after 4 hours was of 0º.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The temperature rose 3º every hour, for 4 hours, hence the total rise was of:
R = 3º x 4 = 12º.
Considering the initial temperature, the the temperature after 4 hours was of:
T = -12º + 12º = 0º.

Deena drinks 2 cups of milk per day. She buys 5 quarts of milk. How many days will her 5 quarts of milk last?
Answer:
10 days
Step-by-step explanation:
Given data
Deena drinks 2 cups of milk per day
from table
1 cup = 0.25 quarts
Hence she drinks
0.5quarts per day
Hence if 0.5quarts last for 1 day
5quarts will last x days
cross multiply
0.5x= 5*1
x= 5/0.5
x=10 days

{PLEASE HELP!! And No Links or I Will Report You!}
Answer:
B
Step-by-step explanation:
Slope intercept form - y = mx + b
where m = slope and y = slope
We are given the slope (-3)
so we would have y = -3x + b
We want to find the y intercept or "b"
To do so we plug in the x and y values of the given coordinate
5 = -3 ( 2 ) + b
we then solve for b
step 1 simplify -3 * 2 = -6
5 = -6 + b
add 6 to each side
5 + 6 = 11
-6 + 6 cancels out
we're left with b = 11
So the equation would be y = -3x + 11

Answer:
7(9+4)
Step-by-step explanation:
7(9+4)
7×9= 63
7×4= 28
Answer:
Monica used 7( 9 + 4 ) as the equivalent expression
Step-by-step explanation:
First off we have to know what 63 + 28 is, that question equals to a sum of 91.
Then, if you use the 7( 9 + 4 ) expression, you multiply 7 to both 9 and 4.
7 x 9 = 63
7 x 4 = 28
Lastly, if you add those two numbers you got you will get the answer of 91.
Therefore, 7( 9 + 4 ) is the answer to the expression.
solve the following Linear equation 15 POINTS
Answer:
24 - 6 = 2(12 - 3)
24 - 6 = 24 - 6
Subtract 24 from both sides of the equation
24 - 24 - 6 = 24 - 6 - 24
-6 = -6
Add 6 to both sides of the equation
6 - 6 = -6 + 6
0 = 0

The planet venus is on average 2.5x10^7 kilometers from earth. The planet mars is on average 2.25x10^8 kilometers from earth. What is the average distance from venus to mars?
Answer:
The average distance from venus to mars is 2.5x10⁸ kilometers.
Step-by-step explanation:
We know:
d₁: average distance between venus and earth = 2.5x10⁷ km
d₂: average distance between mars and earth = 2.25x10⁸ km
We can find the average distance from venus to mars as follows:
[tex] d_{t} = d_{1} + d_{2} [/tex]
First, we need to equal the base power 10 so we can sum both distances:
[tex]2.25 \cdot 10^{8} = 2.25 \cdot 10^{7} \times 10 = 22.5 \cdot 10^{7} km[/tex]
Now, average distance:
[tex]d_{t} = 2.5 \cdot 10^{7} + 22.5 \cdot 10^{7} = (2.5 + 22.5) \cdot 10^{7} = 25 \cdot 10^{7} km = 2.5 \cdot 10^{8} km[/tex]
Therefore, the average distance from venus to mars is 2.5x10⁸ kilometers.

OPTIONS: 75 degrees, 30, 90, or 45
Answer:
x = 45
Step-by-step explanation:
x + 45 + 2x = 180
3x + 45 = 180
3x = 135
x = 45
Answer:
x = 45
Step-by-step explanation:
We know that the three angles of a triangle add up to 180. So we can add all the points equal to 180 to find the value of x.
a + b + c = 180
45 + x + 2x = 180
Combine terms.
45 + 3x = 180
Subtract 45 from both sides.
3x = 135
Divide both sides by 3 to get
x = 45.
To prove this, put x into the original addition of the angles.
45 + x + 2x = 180
Substitute 45 into x.
45 + 45 + 2(45) = 180
Multiply 2 and 45.
45 + 45 + 90 = 180
Add terms.
180 = 180.

The length of arc PR to the nearest hundredth is 7.15 units
How to calculate the length of an arcThe formula for calculating the length of an arc is expressed as:
L = r theta
Given the following parameters
r = PQ = 5 units
theta = <PQR = 82π/180 rad
Substitute to have:
L = 5 * 82π/180 rad
L = 7.15 units
