The water level in the beaker was 10 mL before the small toy was placed into it. After the toy was submerged in the water, the level was 23 mL. The toy has as much volume as how many mL of water?
Answer:
volume of toy = volume of water after placing toy in it - volume of water before placing toy in it
volume of toy = 23mL - 10mL
volume of toy = 13mL
The increase in the volume of water when the toy is submerged in it is equal to the volume of the toy.
SO VOLUME OF WATER IS 13mL

Dave earns 7.50 per hour and has deductions if 36 per week, If Dave works 40 hours per werk, what will his next pay be for 1 week.
Answer:
$264
Step-by-step explanation:
$7.50 * 40 hrs= $300-$36=$264
Answer:
$264 for the week
Step-by-step explanation:
$7.50 per hour for 40 hours (7.50 x 40 = 300)
= $300
Deduction of $36 per week.
$300-$36= $264
Therefore, Dave's next pay for 1 week will be $264.
A Toyota Prius is 178.7 inches long. How many would you need to circle Mars’ equator, which is 13,233 mile long?
Answer:
4,691,902
Step-by-step explanation:
There are 5280 ft per mile, and 12 inches per foot. There are 178.7 inches per Prius. The number needed is ...
(13233 mi)(5280 ft/mi)(12 in/ft)/(178.7 in/Prius)
= (13233×5280×12/178.7) Prius
= 4,691,901.95 Prius
With a little squeezing, you could gain the extra 7.4 inches necessary to round this number to the next higher integer value:
4,691,902 Prius cars would be needed to circle Mars at the equator
Answer:
4,691,902

A length of rope is divided into two pieces in the ratio 2:5 If the longer
piece is 120 m, what is the length of the shorter piece? (SHOW WORKING)
Answer:
The answer is
34.3 mStep-by-step explanation:
To find the length of the shorter piece we must first find the total parts
That's
2 + 5 = 7
Looking at the ratio above we can see that 2 is the smaller part which makes it the shorter piece
Now divide 2 by the total parts and multiply by 120
That's
[tex] \frac{2}{7} \times 120 \\ = \frac{240}{7} \\ = 34.285714[/tex]
We have the final answer as

(PLS HELP ASAP) A basketball player scored 351 points last year. If the player plays 18 games this year, how many points will he need to average per game to beat last year’s total?
Answer:
I think it's 19 I'm pretty sure
Answer:
20
Step-by-step explanation:
The first step would be to divide 351 by 18 to see what score he would need to tie his previous record. The answer to that would be 19.5, so if you round to the nearest whole, you would get 20.

Convert 0.83 into a fraction.
0.83 * 100 = 83, so 0.83 = 83/100.
But in case you meant the slightly more interesting repeating decimal, 0.8333...:
Let x denote this number. Then
10x = 8.333...
100x = 83.333...
==> 100x - 10x = 83.333... - 8.333...
==> 90x = 83 - 8 = 75
==> x = 75/90 = 5/6

You plan to rent a car from XYZ Car Rental Company for a flat rate of $35 a
day. If you plan to use the car for 3 days or fewer, you must also pay a $10
insurance fee per day. If you plan to use the car for more than 3 days, there is
a $5 insurance fee per day. Write a piecewise-defined function that models this
function.
Thanks for any help!
Answer:
The piece-wise function is;
[tex]f\left (x \right ) = \begin{cases} \$ 45 \times x & \text{ if } x \leq 3 \ days \\ \$40 \times x & \text{ if } x > 3 \ days\end{cases}[/tex]
Step-by-step explanation:
The flat rate for renting the car = $35 per day
The amount charged as insurance fee per day for renting the car for 3 days or less = $10
The insurance fee charged per day when the car is rented for more than 3 days = $5
Let the number of days = x
Therefore, we have;
For x ≤ 3, f(x) = 35 × x + 10 × x = x × (35+10) = 45·x
For x > 3, f(x) = 35 × x + 5 × x = x × (35+5) = 40·x
Therefore;
The charge rate for renting the car for less than or equal to 3 days = 45·x
The charge rate for renting the car for more than 3 days = 40·x
The piece-wise function can be presented as follows;
[tex]f\left (x \right ) = \begin{cases} \$ 45 \times x & \text{ if } x \leq 3 \ days \\ \$40 \times x & \text{ if } x > 3 \ days\end{cases}[/tex]
Sam is building a model of an antique car. The scale of his model to the actual car is 1:10. His model is 19.5 inches long. How long is the actual car?
Answer: 195 inches.
Step-by-step explanation:
Given: Sam is building a model of an antique car.
The scale of his model to the actual car is 1:10.
⇒Scale factor = [tex]\dfrac1{10}[/tex]
Since, Length of actual figure = (Length of model ) ÷ Scale factor.
If length of model of car = 19.5 inches.
Then, the length of the actual car = [tex]19.5\div\dfrac{1}{10}=19.5\times10=195\text{ inches}[/tex]
Hence, the length of the actual car = 195 inches.

Answer:
OPTION 2
Step-by-step explanation:
The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular x value. The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.
--------------------------------------------------------------------------
HOW TO: GIVEN A GRAPH, USE THE VERTICAL LINE TEST TO DETERMINE IF THE GRAPH REPRESENTS A FUNCTION.
1.Inspect the graph to see if any vertical line drawn would intersect the curve more than once.
2.If there is any such line, the graph does not represent a function.
3.If no vertical line can intersect the curve more than once, the graph does represent a function.
(The 2nd pic represents a graph that has a function)
At Statebert University, 70% of the students are female. If there are 210 male students
at Statebert U., how many female students are there?
Answer:
490 female students
Step-by-step explanation:
If 70% of students are female, 30% are male.
If 30% of students = 210 students, we can divide both sides of the equation by 3.
30/3 = 10
210/3 = 70
10% of students = 70 students
To get 70% of students, multiply both sides by 7.
10*7 = 70
70 * 7 = 490
70% of students = 490 students
