Answer:
66 cubic units
Step-by-step explanation:
For a prism, the volume is the area of the base multiplied by the height.
area of base = area of triangle = (1/2) * base * height (of the base)
volume = area of base * height of prism
volume = (1/2) * 4 * 3 * 11
volume = 66
Answer:
66 cubic units

An arc with length 5 pi over 4 inches is formed by a 15 degree central angle what is the radius of the circle
Answer:
Radius of the circle is 15 inches.
Step-by-step explanation:
Relation between length of arc, radius and the angle subtended by the arc on center is:
[tex]\theta = \dfrac{l}{r} ..... (1)[/tex]
where [tex]\theta[/tex] is the central angle in radians subtended by arc
[tex]l[/tex] is the length of arc
[tex]r[/tex] is the radius of arc
We are Given the following details:
[tex]l = \dfrac{5\pi}{4}\ inch[/tex]
[tex]\theta = 15^\circ[/tex]
We know that [tex]\pi \ radians = 180 ^\circ[/tex]
Converting [tex]\theta[/tex] to radians:
[tex]\theta =\dfrac{\pi}{180} \times 15[/tex] radians
Putting the values of [tex]\theta[/tex] and [tex]l[/tex] to find the value of [tex]r[/tex]
[tex]\dfrac{\pi}{180} \times 15 = \dfrac{5\pi}{4r}\\\Rightarrow r = \dfrac{45}{3} \\\Rightarrow r = 15 \ inches[/tex]
Hence, Radius of the circle is 15 inches.

Comment on "standard form"
In the US, a number is in standard form if it is written as a sequence of decimal digits and a decimal point (if there is a fractional part), usually with no leading zeros (left of the decimal point). The sign is prepended to that digit string, as shown above.
In the UK, a number is in standard form if it is written in "scientific notation." The rule for writing a number in standard form is that first you write down a number between 1 and 10, then you write ×10(to the power of an integer). Usually powers of 0, or multipliers of 1, are not written. Then the number here is still -4.2, rather than -4.2×10⁰.
Express 5.09 * 10 to the -4 in standard form
Answer:
5.09 x 10^-4 = 0.000509
Step-by-step explanation:
Simply just move the decimal places 4 times to the left and fill in your zeros to get your answer. (I think this is standard form)

Mr. Bond's monthly income is Rs. 2400 and his monthly expenditure on rent is Rs.250. The central angle of the sector representing rent expenses in the pie chart would be ……………
Answer:
[tex]x = 37.5^{\circ}[/tex]
Step-by-step explanation:
The central angle of the sector representing rent expenses in the pie chart is found by simple rule of three:
[tex]x = \frac{Rs. 250}{Rs. 2400}\times 360^{\circ}[/tex]
[tex]x = 37.5^{\circ}[/tex]
In the pie chart, the central angle of the sector reflecting rent expenses is equal to [tex]\boldsymbol{37.5^{\circ}}[/tex]
Pie ChartA pie chart is a circular statistical visual divided into slices to show numerical proportion. The arc length of each slice in a pie chart is proportionate to the quantity it shows.
Monthly income of Mr. Bond [tex]=[/tex] Rs. [tex]2400[/tex]

a car travels at 54 km/h for first 20seconds , 36km/h for next 30seconds and finally 18km/h for next 10 seconds find the averade velocity
Answer:
39 km/h
Step-by-step explanation:
Velocity is the rate of change of distance in a given direction with time. Mathematically,
Velocity = Displacement/time
Like speed, velocity is measured in Km/h or m/s.
Given that the car travels at 54 km/h for first 20seconds,
since 60 seconds = 1 minute and
60 minutes = 1 h,
20 seconds
= 20/(60 ×60) h
= 1/180 h
In the same vein,
30 seconds
= 30 / (60 ×60) h
= 1/120 h
10 seconds
= 10/(60 ×60) h
= 1/360 h
Hence if the car travels 54 km/h for 10 seconds, the distance covered
= 54 × 1/180
= 3/10 Km
If the car travels 36km/h for next 30seconds, the distance covered
= 36 × 1/120
= 3/10 Km
If the car travels 18km/h for next 10 seconds, the distance covered
= 18 × 1/360
= 1/20 km
Total distance = 3/10 Km + 3/10 Km + 1/20 Km
= 13/20 Km
Total time spent = 20 + 30 + 10
= 60 seconds
= 1/60 h
Average velocity = 13/20 km/ 1/60 h
= 39 Km/h

Answer:
r = 8
Step-by-step explanation:
→Distribute the 7 to (-3r + 16):
-16r + 15 + 17 = 7(-3r + 16) - 5r
-16r + 15 + 17 = -21r + 112 - 5r
→Add like terms:
-16r + 32 = -26r + 112
→Add 26r to both sides:
10r + 32 = 112

10r = 80
→Divide both sides by 10:
r = 8
Answer:
Step-by-step explanation:
-16r +15+17= 7(-3r+16)-5r
-16r+32 = -21r +112-5r

Find the area of the square below. Each unit on the grid represents one unit. Make sure you show your work and/or explain how you solved it.
Answer:
Area of the rectangle A = 17 units²
Step-by-step explanation:
Area of the rectangle A = Area of rectangle ACEG - (Area of the triangle ABH + Area of triangle BCD + Area of triangle DEF + Area of the triangle FGH )
Area of rectangle ACEG = Length × Width
= (5 units) × (5 units)
= 25 square units
Area of the triangle ABH = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(4)(1)[/tex]
= 2 units²
Area of the triangle BCD = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(1)(4)[/tex]
= 2 units²
Similarly, area of the triangle DEF = 2 units²
And area of the triangle FGH = 2 units²
Now area of the rectangle A = 25 - (2 + 2 + 2 + 2)
= 25 - 8
= 17 square units
Therefore, area of the rectangle A = 17 square units

A rectangle has sides of 4 and 6 units. Which expression could you use to find the volume (in
cubic units) of the three-dimensional object formed by continuously rotating the rectangle about
the shorter side?
Answer:
144π
Step-by-step explanation:
If the rectangle below is continuously rotated about side, the solid figure formed is a cylinder.
A rectangle with sides of 4 and 6 unit continuously rotated about the shorter side gives a cylinder with a radius (r) of 6 units and a height (h) of 4 units. The volume of a cylinder is given by:
Volume = πr²h
Volume = π × 6² × 4 = 144π
The volume of the cylinder formed is 144π

A swimming pool is being drained at a constant rate of 3 inches (depth of the water) per hour. The depth of the water after 5 hours is 32 inches. Write the equation for this function in point slope form.
Answer:
y-32=3(x-5)
Step-by-step explanation:
The swimming pool is being drained at a constant rate of 3 inches per hour, therefore:
The rate of change, Slope, m=3 inches per hourIf the depth of the water after 5 hours is 32 inches.
The depth is the dependent variable(as its values varies with time) while the time is the independent variable, we can write this as a pair (x,y)=(5, 32).
The point slope form of the equation of a line is of the form: [tex]y-y_1=m(x-x_1)\\(x_1,y_1)=(5,32), m=3\\$Substituting these values, we obtain:\\y-32=3(x-5)\\This is the equation of the function in point slope form.[/tex]

The interval between which the sales of the Marcus were constant was (0, 5) to (5, 6) and (5, 6) to (6, 12)
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given, Marcus tracked the changes in his sales over a 12- month period.
we need to find at which interval was the change in Marcus's sales constant.
First we need to plot the graph, the points given to us will show us the sale of Marcus from the beginning to the end.
The rapid increment is in the number of sales for that period of time is (0, 4) and (0, 5) as we can see a straight line.
Line between point (0, 5) and (5, 6), there is a slant line therefore, which shows that were slow and constant growth in the sale of Marcus as the line is increasing upwards.
The line between the points (5, 6) and (6, 12) is also a slant line but the slope of the line is high than the previous line for points (0, 5) and (5, 6).
Constant growth between these two points and this growth was also constant but it was more rapid as compared to sales between the point (0, 5) and (5, 6).
Therefore the interval between which the sales of the Marcus were constant was (0, 5) to (5, 6) and (5, 6) to (6, 12)
