Assessment started: undefined. Item 1 A rectangle is 12 feet long and 34 feet wide. What is the area of the rectangle? Enter your answer as a fraction in simplest form by filling in the boxes
Area:-
Length×Width12(34)408ft²Answer:
408 ft²
Step-by-step explanation:
Given that,
→ Length (l) = 12 ft
→ Breadth (b) = 34 ft
Formula we use,
→ Area of rectangle = l × b
Then the area will be,
→ l × b
→ 12 × 34
→ 408 ft²
Hence, the area is 408 ft².

The volume of the triangular prism is 108 in³
Step-by-step explanation:
Formula used
Volume of a prism = base area × height
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
Volume of a cube = s³ (where s is the side length)
---------------------------------------------------------------------------------------------------
Question 1⇒ Volume of Figure A = (5 · 7)(2)
= 70 cm³
⇒ Volume of Figure B = (13 · 7)(2)
= 182 cm³
⇒ Total Volume = Volume of Figure A + Volume of Figure B
= 70 + 182
= 252 cm³
The first statement is false.
Rewritten statement:
The volume of figure A can be found by multiplying (5 · 7)(2).
---------------------------------------------------------------------------------------------------
Question 2⇒ Volume of rectangular prism = (15 · 15)(2)
= 450 mm³
⇒ Volume of central cube = 2³
= (2 · 2 · 2)
= 8 mm³
⇒ Total Volume = Volume of rectangular prism - Volume of cube
= 450 - 8
= 442 mm³
The third statement is false.
Rewritten statement:
The total volume of the figure is 442 mm³
---------------------------------------------------------------------------------------------------
Question 3⇒ Volume of rectangular prism = (12 · 3)(8)
= 288 in³
⇒ Volume of triangular prism = (1/2 · 12 · 6)(3)
= 108 in³
⇒ Total Volume = Volume of rectangular prism + Volume of triangular prism
= 288 + 108
= 396 in³
The second statement is false.
Rewritten statement:
The volume of the triangular prism is 108 in³
The shadow of a tower at a time is three times as long as its shadow when the angle of elevation of the Sun is 60°. Find the angle of elevation of the Sum at the time of the longer shadow.
Answer:
[tex]30^{\circ}[/tex].
Step-by-step explanation:
Let [tex]\theta[/tex] denote the unknown angle of elevation. Let [tex]h[/tex] denote the height of the tower.
Refer to the diagram attached. In this diagram, [tex]{\sf A}[/tex] denotes the top of the tower while [tex]{\sf B}[/tex] denote the base of the tower; [tex]{\sf BC}[/tex] and [tex]{\sf BD}[/tex] denote the shadows of the tower when the angle of elevation of the sun is [tex]60^{\circ}[/tex] and [tex]\theta[/tex], respectively. The length of segment [tex]{\sf AB}[/tex] is [tex]h[/tex]; [tex]\angle {\sf ACB} = 60^{\circ}[/tex], [tex]\angle {\sf ADB} = \theta[/tex], and [tex]{\sf BD} = 3\, {\sf BC}[/tex]..
Note that in right triangle [tex]\triangle {\sf ABC}[/tex], segment [tex]{\sf AB}[/tex] (the tower) is opposite to [tex]\angle {\sf ACB}[/tex]. At the same time, segment [tex]{\sf BC}[/tex] (shadow of the tower when the angle of elevation of the sun is [tex]60^{\circ}[/tex]) is adjacent to [tex]\angle {\sf ACB}[/tex].
Thus, the ratio between the length of these two segments could be described with the tangent of [tex]m\angle {\sf ACB} = 60^{\circ}[/tex]:
[tex]\begin{aligned}\tan(\angle {\sf ACB}) &= \frac{\text{opposite}}{\text{adjacent}} = \frac{{\sf AB}}{{\sf BC}}\end{aligned}[/tex].
[tex]\begin{aligned}\frac{{\sf AB}}{{\sf BC}} = \tan(60^{\circ}) = \sqrt{3}\end{aligned}[/tex].
The length of segment [tex]{\sf AB}[/tex] is [tex]h[/tex]. Rearrange this equation to find the length of segment [tex]{\sf BC}[/tex]:
[tex]\begin{aligned} {\sf BC} &= \frac{{\sf AB}}{\tan(\angle ACB)} \\ &= \frac{h}{\tan(60^{\circ})}\\ &= \frac{h}{\sqrt{3}} \\ &\end{aligned}[/tex].
Therefore:
[tex]\begin{aligned}{\sf BD} &= 3\, {\sf BC} \\ &= \frac{3\, h}{\sqrt{3}} \\ &= (\sqrt{3})\, h\end{aligned}[/tex].
Similarly, in right triangle [tex]{\sf ABD}[/tex], segment [tex]{\sf AB}[/tex] (the tower) is opposite to [tex]\angle {\sf ADB}[/tex]. Segment [tex]{\sf BD}[/tex] (shadow of the tower, with [tex]\theta[/tex] as the angle of elevation of the sun) is adjacent to [tex]\angle {\sf ADB}[/tex].
[tex]\begin{aligned}\tan(\angle {\sf ADB}) &= \frac{\text{opposite}}{\text{adjacent}} = \frac{{\sf AD}}{{\sf BD}}\end{aligned}[/tex].
[tex]\begin{aligned}\frac{{\sf AB}}{{\sf BD}} = \tan(\theta) \end{aligned}[/tex].
Since [tex]{\sf AB} = h[/tex] while [tex]{\sf BD} = (\sqrt{3})\, h[/tex]:
[tex]\begin{aligned}\tan(\theta) &= \frac{{\sf AB}}{{\sf BD}} \\ &= \frac{h}{(\sqrt{3})\, h} \\ &= \frac{1}{\sqrt{3}}\end{aligned}[/tex].
Therefore:
[tex]\begin{aligned}\theta &= \arctan\left(\frac{1}{\sqrt{3}}\right) \\ &= 30^{\circ}\end{aligned}[/tex].
In other words, the angle of elevation of the sun at the time of the longer shadow would be [tex]30^{\circ}[/tex].

There are no pairs of congruent sides, so the triangles cannot be proven congruent.
Jonah and Tito were practicing for the upcoming track meet. Jonah finished 5 laps in 9 minutes, while Tito finished 7 laps in 11.2 minutes, each running at a steady pace. Who is running at a faster rate?
Since the unit rate of Tito is greater than that of Jonah, hence Tito is running at a faster rate
Unit ratesThe ratio of distance covered by an object to tme taken is unit rate.
Calculate the unit rate for both Jonah and Tito
For Jonah
Unit rate = 5laps/9minutes
Unit rate = 0.56 laps per minute
For Tito
Unit rate = 7laps/11.2minutes
Unit rate = 0.625laps per minute
Since the unit rate of Tito is greater than that of Jonah, hence Tito is running at a faster rate

Answer:
1125 m
Step-by-step explanation:
Given equation:
[tex]h=-5t^2+150t[/tex]
where:
h = height (in metres)t = time (in seconds)Method 1
Rewrite the equation in vertex form by completing the square:
[tex]h=-5t^2+150t[/tex]
[tex]\implies h=-5t^2+150t-1125+1125[/tex]
[tex]\implies h=-5(t^2-30t+225)+1125[/tex]
[tex]\implies h=-5(t-15)^2+1125[/tex]
The vertex (15, 1125) is the turning point of the parabola (minimum or maximum point). As the leading coefficient of the given equation is negative, the parabola opens downward, and so vertex is the maximum point. Therefore, the maximum height is the y-value of the vertex: 1125 metres.
Method 2
Differentiate the function:
[tex]\implies \dfrac{dh}{dt}=-10t+150[/tex]
Set it to zero and solve for t:
[tex]\implies -10t+150=0[/tex]
[tex]\implies 10t=150[/tex]
[tex]\implies t=15[/tex]
Input found value of t into the original function and solve for h:
[tex]\implies -5(15)^2+150(15)=1125[/tex]
Therefore, the maximum height is 1125 metres.
Convert to vertex form y=a(x-h)²+k
h=-5t²+150t+1125-1125h=-5t²+150t-1125+1125h=-5(t²-30t+225)+1125h=-5(t-15)²+1125Vertex at (15,1125)
As a is negative parabola is opening downwards hence vertex is maximum

Determine the equation of the circle graphed below.
Answer:
x^2 + y^2 = 49
Step-by-step explanation:
The equation of a circle is given by
( x-h) ^2 + (y-k) ^2 = r^2
(h,k) is the center of the circle and r is the radius
The circle is centered and (0,0) and the radius is 7
( x-0) ^2 + (y-0) ^2 = 7^2
x^2 + y^2 = 49
An amateur soccer ball is priced at
$19.50. This is 3/4ths the price of a
professional ball. What is the price of
the professional ball?
Answer: $26
Step-by-step explanation:
If $19.50 is 3/4, we need to find 4/4.
3/4 -> 0.75
4/4 -> 1
We will set up a proportion and solve.
[tex]\frac{19.5}{0.75} =\frac{x}{1}[/tex]
19.5 = 0.75x
26 = x
The professional ball is $26.
Answer:
$26
Step-by-step explanation:
19.50 = 3/4
so
to find 1/4, we do 19.50 / 3 = 6.5
6.5 = 1/4
so the price of a professional ball would be 4/4 (1 whole)
6.5 x 4 = 26
Hope this makes sense.

If quadrilateral H is a scaled copy of quadrilateral G then the value of i is 36.
What is Quadrilateral?A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.
Given that Quadrilateral H is a scaled copy of quadrilateral G.
Two quadrilaterals are similar if their corresponding angles are equal and also their corresponding sides must be proportional.
The sides are proportional.
40/32 = 45/i
We have to find the value of i
Apply cross multiplication
40i=45(32)
40i = 1440
Divide both sides by 40
i = 1440/40
i = 36
Hence, if quadrilateral H is a scaled copy of quadrilateral G then the value of i is 36.

B. x=4
C. x= 3

F. x= -1/-2
Answer:
E and F.
Step-by-step explanation:
This can be written in quadratic formula.
x = -b +- √b² - 4ac/2a
The equation to solve is written as ax² + bx + c = 0.
a = 2, b = 7, c = 3
x = -7 +- √49 (7²) - 24 (4*2*3, or 4ac).
x = -7 +- √25
x = -7 +- 5
divide by 2a (4)
-7/4 = -1.75
5/4 = 1.25
now we do -1.75 +- 1.25
x = -1/2 (F.)
x = -3 (E.)
