FIRST CORRECT ANSWER GETS BRAINLIEST!!!!!!!! Suppose you were digging at a rate of 10 feet per day. Assume you are ar sea level when you begin digging. If there are 365 days in a year, write an equation to represent the depth of the hole where d= depth in feet and t= time in years
Answer:
simple
Step-by-step explanation:
365 x 10 = 3650 feet
took you 1 year
and adding on sea level 1,312 feet
3650 + 1,312 = 4962 in 1 year

true or false: sin 50* = sin 130*
Answer:
True
Step-by-step explanation:
sin(130)
sin(180-50)
By difference rule for sine
sin(180)cos(50)-sin(50)cos(180)
0*cos(50)-sin(50)*-1
0+sin(50)
sin(50)
The answer is true.
Make x the subject of the formula
6(a – cx) = 24
Answer:
x = (a-4)/c
Step-by-step explanation:
1) Multiply 6 for a and -cx
6a - 6cx = 24
2) Add -6a at the two members
-6cx + 6a -6a = 24-6a
-6cx = 24 -6a
3) Multiply the two members by -1
6cx = 6a - 24
4) divide the two members by 6c (assuming that its values is not 0)
x = (6a-24)/6c
5) simplify the second member
x = [6(a-4)]/6c
x = (a-4)/c
A cylindrical soup can has a radius of 1.1 in. and is 5.4 in. tall. Find the volume of the can and round to the nearest tenths if necessary
Answer:
[tex]V=20.52\ in^3[/tex]
Step-by-step explanation:
Given that,
The radius and the height of the cylindrical soup can are 1.1 inch and 5.4 inch.
We need to find the volume of the can.
The formula for the volume of the can is given by :
[tex]V=\pi r^2 h\\\\V=\pi \times (1.1)^2 \times 5.4\\\\V=20.52\ in^3[/tex]
So, the volume of the can is equal to [tex]20.52\ in^3[/tex].

The volume of the polyhedron is ______ yd3.
Answer:
122,850 yd³
Step-by-step explanation:
The polyhedron is a right triangle prism
Area of the right triangle prism = ½*a*c*h
a = 91 yd
c = 60 yd
h = 45 yd
Volume = ½*91*60*45
= 122,850 yd³

PLS HELP ASAP WILL MARK BRAINLY!!!. In a bag there are 3 red marbles, 2 yellow marbles and 1 blue marble. After a marble is selected, it is replaced. After 40 attempts at drawing two marbles from the bag, there were three instances where a blue marble then a yellow marble was pulled. What is the experimental probability of pulling a blue marble and then a yellow marble? 0.0556 0.0750 0.0167 0.0333
Answer:
0.0750 I took the test
The experimental probability of pulling a blue marble and then a yellow marble is 0.075 or 7.5%, which is closest to answer option B.
What is probability?Probability is a statistical term that describes the possibility that something will occur.
Since there is only one blue marble in the bag, the likelihood of getting a blue marble on the first draw is 1/6.
After the blue marble is replaced, the probability of drawing a yellow marble on the second draw is 2/6, since there are now 2 yellow marbles out of a total of 6 marbles in the bag.
The probability of sketching a blue marble and subsequently a yellow marble in the same attempt is:
P(blue then yellow) = P(blue) x P(yellow | blue)
P(blue then yellow) = (1/6) x (2/6)
P(blue then yellow) = 1/18
Since the marbles are replaced after each draw, the probability of drawing a blue marble and then a yellow marble is independent of one attempt to the next.
The experimental probability of pulling a blue marble and then a yellow marble in 40 attempts can be calculated by dividing the number of times it occurred by the total number of attempts:
Experimental probability = number of times blue then yellow was pulled / total number of attempts
Experimental probability = 3 / 40
Experimental probability = 0.075
Therefore, the experimental probability of pulling a blue marble and then a yellow marble is 0.075 or 7.5%.

Answer:
754 ft²Step-by-step explanation:
Given
d = 24 fth = 4 ftRequired amount of vinyl:
πdh + πd²/4 =3.14*24*4 + 3.14*24²/4 = 754 ft² (rounded)There are two spinners containing only white and green slices. Spinner A has 4 white slices and 1 green slice. All the slices are the same size. Spinner B has 3 white slices and 9 green slices. All the slices are the same size. Each spinner is spun. List these events from least likely to most likely. Event : Spinner B lands on a green slice. Event : Spinner A lands on a white or green slice. Event : Spinner A lands on a white slice. Event : Spinner B lands on a yellow slice.
Answer:
Step-by-step explanation:
Ok, lets list the important things
only green and white slicesall slices same sizespinner A has 4/5 white slices and 1/5 green slicesspinner B has 3/12 white slices and 9/12 green slicesThe 4 options are:
spinner B lands on a green slicespinner A lands on a white or green slicespinner A lands on a white slicespinner B lands on a yellow sliceWe already know that choice 2 is 100% probable and option 4 is 0% probability, because in option 2, the spinner A ONLY has white or green slices so the spinner must land on the slice. In option 4, no matter which spinner is spun no yellow slices are available to land on.
the chance of option 1 happening is 9/12 which is 3/4 which is 75%
the chance of option 3 of happening 4/5 which is 80%
option 1 has a 75% chance
option 2 has a 100% chance
option 3 has an 80% chance
option 4 has a 0% chance
this means that the order is:
1. option 4
2. option 3
3. option 1
4. option 2
because it is least likely to most likely.

I = Prt
2100 = 8000(9/12)r
2100 = 600r
2100/600 = r

help please ! solve for u and simplify the answer
Answer:
u = 5
Step-by-step explanation:
[tex]\frac{u + 7}{15} = \frac{4}{5}[/tex]
We want to solve for u. This means we need to isolate u on one side of the equation.
To do this, first multiply both sides by 15. This will cancel out the denominator on the left side.
[tex]u + 7 = (\frac{4}{5})(\frac{15}{1})[/tex]
Multiply the numerators and denominators separately.
4 • 15 = 60
5 • 1 = 5
[tex]u + 7 = \frac{60}{5}[/tex]
Simplify the fraction.
60 ÷ 5 = 12
u + 7 = 12
Subtract 7 from both sides.
u = 5
Check your work by plugging u = 5 back into the original equation.
[tex]\frac{5 + 7}{15} = \frac{4}{5}[/tex]
[tex]\frac{12}{15} = \frac{4}{5}[/tex]
[tex]0.8 = 0.8[/tex]
Your answer is correct.
Hope this helps!
Answer:
5 is your answer for u.
Step-by-step explanation:
Note the equal sign, what you do to one side of the equation, you do to the other.
First, multiply 15 and 5 to both sides of the equation (to get rid of the denominators):
[tex]15 * 5 * (\frac{u + 7}{15}) = (\frac{4}{5}) * 5 * 15\\5 * (u + 7) = 4 * 15[/tex]
First, distribute the 5 to all terms within the parenthesis. Also, simplify the right side by multiplying:
[tex]5 * (u + 7) = 4 * 15\\(5 * u) + (5 * 7) = (4 * 15)\\5u + 35 = 60[/tex]
Next, isolate the variable, u. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract 35 from both sides, and then divide by 5 to isolate the variable, u:
[tex]5u + 35 = 60\\5u + 35 (-35) = 60 (-35)\\5u = 60 - 35\\5u = 25\\\\\\\frac{5u}{5} = \frac{25}{5} \\u = \frac{25}{5} = 5\\u = 5[/tex]
