Answer: 797.4 m²
Step-by-step explanation:
The surface area is just the total of the areas of each face of of a solid. In this solid, we have 2 triangles and 3 rectangles.
TrianglesWe know that the two triangles of this solid are congruent, so they will have the same area. Since the area of a triangle is [tex]\frac{1}{2}bh[/tex], two triangles would have an area of [tex]bh[/tex]. Hence, the total area is
[tex]A=9 * 15\\A=135[/tex]
RectanglesThe area of a rectangle is lw, where l is the length and w is the width. Let's find the total area of all of them.
[tex]A=9*16+15*16+17.4*16[/tex]
All of the areas are a product of some number and 16. This makes sense as the length of this prism is 16. We can un-distribute this 16 to make the calculation easier.
[tex]A=16(9+15+17.4)\\A=16(41.4)\\A=662.4[/tex]
TotalWe can add both totals to get the total surface area of the solid.
[tex]135+662.4\\=797.4[/tex]
The surface area of this right triangular prism is 797.4 m².

In the circle below, AB is a diameter. Suppose stack CB equals 32 degrees and m angle B C D equals 52 degrees.
Find the following. Type your numerical answers (without units) in each blank.
The 32° measure of arc CB, and m<BCD which is 52° gives m<BAC and m<ACB as 16° and 90° respectively, from which we have;
m<CBA = 74°m<ACD = 38°Which circle theory can be used to find the required angles?First part;
Given;
Angle subtended by arc CB = 32°
m<BCD = 52°
Based on circle theory, we have;
Angle subtended by an arc at the center of a circle is twice the angle subtended at the circumferenceTherefore;
Arc CB = 2 × m<BAC
Which gives;
Arc CB = 32° = 2 × m<BAC
m<BAC = 32° ÷ 2 = 16°
Angle subtended by the diameter at the circumference is 90°.
Therefore;
m<ACB = 90°
In triangle ∆ABC, we have;
m<ACB + m<BAC + m<CBA = 180°
m<CBA = 180° - (m<ACB + m<BAC)
Therefore;
m<CBA = 180° - (90° + 16°)
m<CBA = 180° - (90° + 16°) = 74°
m<CBA = 74°Second part;
The arc subtending m<ACD is AB which is also the diameter.
Angle formed by the diameter, which is a straight line = 180°
Therefore;
Angle subtended at the center by arc AB = 180°
Angle subtended at the circumference, m<ACB is therefore;
m<ACB = 180° ÷ 2 = 90°
A
m<ACB = m<ACD + m<BCD (Angle addition property)
Therefore;
90° = m<ACD + 52°
m<ACD = 90° - 52° = 38°

Find parametric equation for the tangent line to the curve given by x(t)=e^-t cos(t), y(t) =e^-t sin(t), z(t)=e^-t and point p(1,0,1)
The parametric equation for the tangent line to the curve is x = 1 - t, y = t, z = 1 - t.
For this question,
The curve is given as
x(t)=e^-t cos(t),
y(t) =e^-t sin(t),
z(t)=e^-t
The point is at (1,0,1)
The vector equation for the curve is
r(t) = { x(t), y(t), z(t) }
Differentiate r(t) with respect to t,
x'(t) = -e^-t cos(t) + e^-t (-sin(t))
⇒ x'(t) = -e^-t cos(t) - e^-t sin(t)
⇒ x'(t) = -e^-t (cos(t) + sin(t))
y'(t) = - e^-t sin(t) + e^-t cos(t)
⇒ y'(t) = e^-t ((cos(t) - sin(t))
z'(t) = -e^-t
Then, r'(t) = { -e^-t (cos(t) + sin(t)), e^-t ((cos(t) - sin(t)), -e^-t }
The parameter value corresponding to (1,0,1) is t = 0. Putting in t=0 into r'(t) to solve for r'(t), we get
⇒ r'(t) = { -e^-0 (cos(0) + sin(0)), e^-0 ((cos(0) - sin(0)), -e^-0 }
⇒ r'(t) = { -1(1+0), 1(1-0), -1 }
⇒ r'(t) = { -1, 1, -1 }
The parametric equation for line through the point (x₀, y₀, z₀) and parallel to the direction vector <a, b, c > are
x = x₀+at
y = y₀+bt
z = z₀+ct
Now substituting the (x₀, y₀, z₀) as (1,0,1) and <a, b, c > into x, y and z, respectively to solve for the parametric equation of the tangent line to the curve, we get
x = 1 + (-1)t
⇒ x = 1 - t
y = 0 + (1)t
⇒ y = t
z = 1 + (-1)t
⇒ z = 1 - t
Hence we can conclude that the parametric equation for the tangent line to the curve is x = 1 - t, y = t, z = 1 - t.

Translate and solve using proportions. What number is 63% of 190?
Answer:
Step-by-step explanation:
190/x=100/63
(190/x)*x=(100/63)*x - we multiply both sides of the equation by x
190=1.5873015873016*x - we divide both sides of the equation by (1.5873015873016) to get x
190/1.5873015873016=x
119.7=x
x=119.7
now we have:
63% of 190=119.7
You are requesting a number, as the question clearly states. So, a number should be the response. However, because 63 and 190 are not stated and might indicate a variety of things, we must make an assumption in order to provide a response.
We will thus assume that 63 is a percentage and that 190 is a number in order to respond to the question, "What number is 63 of 190?"
We multiply 63 by 190 and then divide the result by 100 to obtain the solution. Here is the calculation and response to your query:
⇒ 63 x 190 = 11970
⇒ 11970 / 100 = 119.7
Assuming you meant 63 percent of 190, the answer to the question "What number is 63 of 190?" is 119.7, as shown and computed above.
Thank you,

if an average orange weighs 75 g, how many oranges would weigh 4.5 kg?
Answer: 60 oranges
Step-by-step explanation:
Given information
Weight = 75 g / orange
Total = 4.5 kg
Given formula
Total = Number of oranges × Average weight
Convert Kilogram unit to Gram
1 kg = 1000 g
4.5 kg = 4.5 × 1000 = 4500 g
Substitute values into the given formula
Total = Number of oranges × Average weight
Number of oranges = Total / Average weight
Number of oranges = 4500 / 75
Simplify by division
[tex]\Large\boxed{Number~of~oranges~=~60}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
60 oranges
Step-by-step explanation:
Let the unknown number of oranges be x.Given that,The average weight of an orange ⇒ 75g
Total weight of oranges ⇒ 4.5 kg
Therefore,Number of oranges Weight ( in grams)
1 75 g
x (4.5 × 1000) g
To find the number of oranges we can make an expression like this.1 ⇒ 75
x ⇒ 4500
Use cross multiplication and find the value of x.
75x = 4500 × 1
75x = 4500
Divide both sides by 75.
x = 60

Which ideas did you include in your response? Check all that apply.
Henry will need 15 pints altogether.
The number of pints of yellow (3) is multiplied by 3 to get 9, so he would multiply 2 by 3 to get 6 pints of red.
Add: 6 + 9 = 15 pints.
Answer:
All answers are correct.
Step-by-step explanation:
Henry needs a total of 15 pints.
3 pints of yellow multiplied by 3 gives 9 pints of yellow, he needs 6 pints of red to get to 15, so he multiplies 2 pints of red by 3 to get 6 pints of red.
You add 9 + 6 to get the total of 15 pints he needs.
Emma bought snacks for her team's practice. She bought a bag of chips for $2.27 and a 24-pack of juice bottles. The total cost before tax was $51.23. Write and solve an equation which can be used to determine jj, how much each bottle of juice cost.
Answer:
each bottle of juice costs $2.04

What is a linear function?The word linear function in mathematics refers to two distinct but related concepts. A linear function in calculus and related fields is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.To find the linear function which represents the line given by the point-slope equation:
Given: [tex]y-8=\frac{1}{2} (x-4)[/tex]
Distribute the right side:
[tex]y-8=\frac{1}{2} (x)-\frac{1}{2} 4\\y-8=\frac{1}{2} x-2[/tex]
Adds 8 on both sides:
[tex]y=\frac{1}{2}x-2+8\\y=\frac{1}{2}x+6[/tex]
Convert to function notation:
[tex]f(x)=y\\f(x)=\frac{1}{2} x+6[/tex]
Therefore, the linear function which represents the line given by the point-slope equation is (B) [tex]f(x)=\frac{1}{2} x+6[/tex].

An Escalator Moves At The Rate Of 2 Feet Per Second. At What Rate Does The Escalator Move In Miles Per Hour?
A)0.02 mph
B)0.34 mph
C)0.68 mph
D)1.36 mph
Answer:
1.36mph
Step-by-step explanation:
The escalator is moving at 2ft/s, lets convert this to miles/second.
2ft/s = 0.000378788miles/s.
Now that we have the miles/second lets multiply this value by 3600 to get the miles/h, because there are 3600 seconds in an hour.
2ft/s=1.3636368miles/h
Or approximately 1.36miles/h.
