Answer:
x = 5 1/3 hours
Step-by-step explanation:
Let
x = number of hours Mia fills the pool
y = number of hours Lora fills the pool
x + y = 16
Lora fills the pool twice as fast as mia.
y = 2x
Substitute y =2x into the equation
x + y = 16
x + 2x = 16
3x = 16
x = 16/3
x = 5 1/3 hours
x = number of hours Mia fills the pool =5 1/3 hours
could someone please help me?
Answer:
A. [tex]Log_p N = b \ and \ b^p = N[/tex]
Step-by-step explanation:
A. The given options are;
[tex]Log_p N = b \ and \ b^p = N[/tex]
For [tex]Log_p N = b[/tex] we have;
[tex]p^b = N[/tex]
However;
[tex]b^p = N[/tex]
Where, p ≠ b
[tex]p^b \neq b^p[/tex]
Therefore;
N ≠ N for the given pair and the pair are therefore, not equivalent
B. x = √y and [tex]x = y^{1/2}[/tex]
We note that
x = √y = [tex]y^{1/2}[/tex]
We have;
x = [tex]y^{1/2}[/tex], by transitive property
Therefore, the pair, x = √y and [tex]x = y^{1/2}[/tex] are equivalent
C. [tex]Log_b N = p \ and \ b^p = N[/tex]
From [tex]Log_b N = p[/tex], we have;
[tex]b^p = N[/tex]
Therefore, [tex]Log_b N = p \ and \ b^p = N[/tex] are equivalent pairs as [tex]b^p = N[/tex] can be obtained from [tex]Log_b N = p[/tex]
D. ㏑x = y and x = [tex]e^y[/tex]
[tex]ln \ x = ln_e \ x = y[/tex], therefore, by rules of logarithm, we have;
x = [tex]e^y[/tex]
Therefore, ㏑x = y and x = [tex]e^y[/tex] are equivalent pairs, as x = [tex]e^y[/tex] can be obtained from ln x.
Therefore;
The option which are not equivalent pair is option is [tex]Log_p N = b \ and \ b^p = N[/tex]

The answer is [tex]a^{2} -(2*4)[/tex]
Step-by-step explanation:Definition of square and rectangle
A plane figure having four equal sides and four right (90°) angles in geometry is called a square.
A rectangle is a two-dimensional shape with four sides, four corners, and four right angles. A rectangle's opposite sides are the same length, with one pair being longer than the other.
The area of given square= a²
The area of rectangle= 2*4
Hence the area of shaded region= [tex]a^{2} -(2*4)[/tex]

Step-by-step explanation:
there are 14 red marbles and 19 blue marbles in a bag you randomly choose one of the marbles what is the probability of choosing a red marble write your answer as a fraction in simplest form
Answer:
4/23
Step-by-step explanation:
Probability of choosing a red marble = # of red marbles / total # of marbles
We are told that there are 4 red marbles and 19 blue marbles
So the # of red marbles = 4
And the total # of marbles = 4 + 19
4 + 19 = 23
So there are a total of 23 marbles
Recall that probability of choosing a red marble is equal to # of red marbles / total # of marbles
Hence, the probability of choosing a red marble is 4/23
Note: 4/23 is already in it's simplest form so no simplifying has to be done.
Answer:
14/33
Step-by-step explanation:
There are 14 red marbles and 19 blue marbles, meaning that there are 33 marbles in all:
14 + 19 = 33
You are randomly choosing a red marble out of the total amount of marbles. 14/33
Note that you cannot simplify the fraction anymore, and so 14/33 is your answer.

In the figure below , m
Answer:
∠1 = 52
∠2 = 128
∠4 = 128
Step-by-step explanation:
∠3 and ∠1 are vertical angles
As we now vertical angles are congruent
So if ∠3 = 52°, then ∠1 also equals 52°
∠3 and ∠4 are supplementary angles
supplementary angles add up to equal 180
Thus, ∠3 + ∠4 = 180
If ∠3 = 52°
Then 52 + ∠4 = 180
180 - 52 = 128
Hence, ∠4 = 128
∠4 and ∠2 are vertical angles
Like stated previously vertical angles are congruent
So if ∠4 = 128 then ∠2 also equals 128
Find the value of x and show all steps please
Answer:
x = 88
Step-by-step explanation:
Opposite angles in a quadrilateral inscribed in a circle are supplementary
Supplementary meaning that the sum of the two angle measures is 180
The opposite angle of "x" is ∠B which has a measure of 92°
Thus, 92 + x = 180
180 - 92 = 88
Hence, x = 88

-x = 10
I will____ both sides by_____
x= _____
Answer:
I will subtract both sides by 10. X=-10
Step-by-step explanation:
X= -10 because if you subtract it to -x it will cancel out the negative.
Answer:
I will divide both sides by -1.
x = -10
Step-by-step explanation:
To solve this, we have to isolate x on one side of the equation. In this equation, 10 = -x.
Remember that the coefficient of a single variable is always 1, so 1x = x. We have -x, which means it's actually -1x. Solve using -1x instead of -x.
[tex]-x=10[/tex]
[tex]-1x=10[/tex]
Divide both sides by -1 to isolate x.
[tex]\frac{-1x}{-1} =\frac{10}{-1}[/tex]
Simplify.
[tex]x = -10[/tex]
x is equal to -10.
The answer is I will divide both sides by -1.
x = -10

Manuel wants to build a model of Captain America's famous shield out of cardboard. The outer ring of the shield is colored red. The next ring is white. The third ring is also red. The center is blue with a white star. The radius of the whole shield is 14 inches. However, Manuel just wants to know the area of the space he needs to paint red. Use 3.14 for Pi. Round to the nearest hundredth
Answer:
615.44 in²
Step-by-step explanation:
The shape of Captain America's shield = Circular
The area of a circle = πr²
The radius of the whole shield = 14 inches.
The first ring = Red ring
Hence, the area of the red ring =
π = 3.14
3.14 × 14²
= 615.44 in²
The area of the space he needs to paint red is 615.44 in²
