Flo and Carl each must read a 500-page book. Flo reads one page every minute. Carl reads one page every 50 seconds. Flo starts reading at 1:00, and Carl starts reading at 1:30. When will Carl catch up to Flo?
Answer:
Carl will catch up Flo at 4:00Step-by-step explanation:
Given
Flo reads one page every minuteCarl reads one page every 50 secondsCarl starts 30 minutes lateMax number of pages = 500Let x be the number of pages each reads when Carl catches up Flo
Then we have the time for Flo and Carl
Flo:
x pages after x minutesCarl:
x pages after 30 + x*50/60 minutesThe time is same:
x = 30 + 50/60xx = 30 + 5/6xx - 5/6x = 301/6x = 30x = 6*30x = 180180 minutes = 3 hours
1:00 + 3 hours = 4:00
✭Flo and carl must read a 500 page book.
✭Flo reads one page every 1 minute (60seconds).
✭Carl reads one page every 50 Seconds.
✭Flo starts reading at 1:00.
✭Carl starts reading at 1:30.
[tex]\large\bold{\underline{\underline{To \: Find:-}}}[/tex]When will carl catch up to flo?
[tex]\large\bold{\underline{\underline{Solution:-}}}[/tex]Let Flo read certain pages when carl catches up with him. Then carl also read the same amount pages at that time.
Let the time passed be "x" minutes.
If carl Reads 1 page every 50 seconds, then 50 seconds can be written as 5/6th of a minute.
Carl's rate will be:
[tex]Carl \: \: Rate \: = \frac{Page}{Minutes} = \frac{ \frac{1}{5} }{6} = \frac{6}{5} [/tex]Now, flo got a 30 minute head start. therefore, when carl catches up, he will read certain pages at x + 30 minutes.
And the number of pages that carl read after the time he had started, that is, "x" minutes will be:
[tex] ⇒\frac{6}{5} \times x[/tex]But, the number of pages carl and flo read will be the same at that time!
[tex] ⇒\frac{6x}{5} = x + 30[/tex][tex] ⇒\frac{6x}{5} - x = 30[/tex][tex] ⇒\frac{x}{5} = 30[/tex][tex]⇒x = (30 \times 5) \: \: minutes[/tex][tex]⇒x = (150) \: \: minutes[/tex]So carl catches up after 150 minutes.
Now, 1:30 + 150 minutes = 1.5 hours + 2.5 hours = 4:00.
Carl will catch up at 4:00.Solve the inequality for x:
4x - 28 > 16
We have:
4x - 28 > 16
Add 28 to both sides:[tex]4x-28+28>16+28[/tex]
Simplify:4x > 44
Divide both sides by 4:[tex]\dfrac{4x}{4}>\dfrac{44}{4}[/tex]
Simplify:[tex]\boxed{x>11}[/tex]

Answer:
Second option
Step-by-step explanation:
In order to find the answer to this question you have to divide the numerator into the denominator remembering that whole numbers have a secret decimal point to the right of itself.
[tex]\frac{3}{18}[/tex]
[tex]\frac{3}{18} =3\div18[/tex]

What are the values of a and b?
a=
b=
Answer:
The values of a and b are:
a = 2[tex]b=4[/tex]Step-by-step explanation:
Given the exponential model
[tex]y=a\cdot \:b^x[/tex]
Given the points
(0, 2) and (3, 128)
We know that the y-intercept of [tex]y=a\cdot \:b^x[/tex] is (0, a).
so
a = 2
putting x = 3, y = 128 and a = 2
[tex]y=a\cdot \:b^x[/tex]
[tex]128=2\cdot \:b^3[/tex]
Switching sides
[tex]2b^3=128[/tex]
[tex]\frac{2b^3}{2}=\frac{128}{2}[/tex]
[tex]b^3=64[/tex]
Taking the real value such as:
[tex]\mathrm{For\:}x^3=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt[3]{f\left(a\right)}[/tex]
so
[tex]b=\sqrt[3]{64}[/tex]
[tex]b=\sqrt[3]{4^3}[/tex]
[tex]b=4[/tex]
Therefore,
a = 2[tex]b=4[/tex]The weights in a weighted mean can be relative frequencies

WHAT IS THIS QUESTION ABOUT?
Step-by-step explanation:
What is the area of the figure?
Answer: 17.5 square yards
================================================
Work Shown:
base = 5 yards
height = 7 yards
The base and height are always perpendicular to one another
area of triangle = 0.5*(base)*(height)
area of triangle = 0.5*(5)*(7)
area of triangle = 17.5 square yards
The other values aren't used. They're likely thrown in as a distraction.

Answer:
x = 85°, y = 30°
Step-by-step explanation:
40° + x + 55° = 180°
x + 95° = 180°
x = 85°
85° + 65° + y = 180°
150° + y = 180°
y = 30°
Find the indicated values, where g(t)=t^2-t and f(x)=1+x g(f(2)+3)
Answer:
[tex]g(f(2)+3)=30[/tex]
Step-by-step explanation:
We have the two functions:
[tex]g(t)=t^2-t\text{ and } f(x)=1+x[/tex]
And we wish to find:
[tex]g(f(2)+3)[/tex]
First, let’s find f(2) first. So, we will substitute 2 for x for f(x):
[tex]f(2)=1+(2)=3[/tex]
Hence, we can now substitute 3 for f(2):
[tex]g(f(2)+3)=g(3+3)=g(6)[/tex]
Now, we can find g(6). Substitute 6 for t for g(t):
[tex]g(6)=(6)^2-(6)=36-6=30[/tex]
Therefore:
[tex]g(f(2)+3)=30[/tex]
If a couple has 3 children, what is the probability of all three children being girls? Justify.
Answer:
The probability of all three children being girls will Be: 1/8
Step-by-step explanation:
The couple has 3 children.
We have to determine the probability of all three children being girls.
As we know that for each child, the probability of being a girl is ' [tex]\frac{1}{2}[/tex] ' as is the probability of being a boy is ' [tex]\frac{1}{2}[/tex] '.
so for there to be all girls, the probability will be:
P ( all girls) = 1/2 × 1/2 × 1/2 = 1/8
Therefore, the probability of all three children being girls will Be: 1/8

Determine whether the planes are parallel, perpendicular, or neither.8x + 8y + 8z = 1, 8x − 8y + 8z = 1 parallel perpendicular neither Correct: Your answer is correct.If neither, find the angle between them. (Round your answer to one decimal place. If the planes are parallel or perpendicular, enter PARALLEL or PERPENDICULAR, respectively.)
Answer:
The answer is "[tex]\bold{\theta= 70.53^{\circ}}[/tex]"
Step-by-step explanation:
The given value:
[tex]8x+8y+8z = 1\ and \ 8x-8y+8z = 1[/tex]
When the normal vectors are in the plane:
[tex]n_1 = < 8,8,8 > \ and \ n_2 = < 8, -8, 8>:[/tex]
Because the two variables really aren't proportional to each other and the wings are not parallel.
Let us just find that two vectors' dot product.
[tex]n_1 \cdot n_2 =<8,8,8> < 8,—8,8>\\\\ = 64-64+ 64 \\\\ = 64 \neq 0[/tex]
Therefore, we won't find that angle between both the given planes as parallel.
[tex]\cos \theta = \frac{n_1 \cdot n_2}{|n_1||n_2|}\\\\\cos \theta =\frac{64}{\sqrt{192} \sqrt{192}}\\\\\cos \theta =\frac{64}{8\sqrt{3} 8\sqrt{3}}\\\\\cos \theta = \frac{1}{3}\\\\ \theta = 70.53^{\circ}[/tex]
It is required to know the orientation of one plane relative to the other.
The angle between the planes is 70.5°.
PlanesThe given planes are
8x + 8y + 8z = 1
8x − 8y + 8z = 1
Parallel
[tex]\dfrac{8}{8}=\dfrac{8}{-8}=\dfrac{8}{8}\\\Rightarrow 1\neq -1\neq 1[/tex]
The planes are not parallel.
Perpendicular
[tex]8\times 8+8\times -8+8\times8=64\neq 0[/tex]
The planes are not perpendicular as dot product is not 0.
Finding angle
[tex]\theta=\cos^{-1}\dfrac{8\times 8+8\times -8+8\times8}{\sqrt{8^2+8^2+8^2}\sqrt{8^2+(-8)^2+8^2}}\\\Rightarrow \theta=\cos^{-1}\dfrac{1}{3}\\\Rightarrow \theta=70.53^{\circ}[/tex]

Step-by-step explanation:
A cab company charges $4 per cab ride, plus an additional $2 per mile driven. Write an equation that shows the relationship between the distance x and the cost y. Write your answer as an equation with y first, followed by an equals sign.
Answer:
y = 2x + 4
Step-by-step explanation:
So, the cab company charges a flat fee of $4 per cab ride, meaning 4 has no variables in the equation. Now, x is the distance, and the cab company charges $2 per mile driven. Per mile driven is a distance unit, so the x goes with the 2. From that, you can get that the cost is equal to 4 dollars plus 2x (2 times the distance in miles). This is y = 2x+4.

There are 2 value's in a game. one of them is Pancake, the other is waffle. Pancakes are worth 1.5x a waffle. I have 10 waffles, how much Pancake value do I have?
Answer:
Approximately 6.67 pancakes.
Step-by-step explanation:
We can write an equation that relates the two items.
Let P represent Pancake and let W represent Waffle.
Pancakes are worth 1.5 times a Waffle. Therefore:
[tex]W=1.5P[/tex]
To find the Pancake value for 10 Waffles, we can substitute 10 for W and solve for P. Therefore:
[tex]\begin{aligned} W&=1.5P \\ 10&=1.5P \\ 6.\overline{6}&=P \end{aligned}[/tex]
Hence, 10 Waffles equates to approximately 6.67 pancakes.
