Leonard made the 3-d shape below for an art project. He wants to paint it blue.
How many square centimeters of paint does he need to paint the outside of every
side except for the bottom?
10 cm
6 cm
Answer:
90 [tex]cm^{2}[/tex] of blue paint
Step-by-step explanation:
From the given diagram, the sides have the same dimensions and the shape of a triangle.
Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height
Given that, the base of each side = 6 cm, and the height = 10 cm.
Then,
Area of each side of the shape = [tex]\frac{1}{2}[/tex] x 6 x 10
= 30 [tex]cm^{2}[/tex]
Since Leonard wish to paint only the 3 sides and not the bottom part of the shape, the amount of paint required can be determined as;
3 x area of each side = 3 x 30
= 90 [tex]cm^{2}[/tex]
Leonard would need 90 [tex]cm^{2}[/tex] of paint to paint the sides of the shape.
What is b if 5(590-b)=100
Answer:
b=570
Step-by-step explanation:
5(590-b)=100
multiplying 5 with right hand side
2950-5b=100
2950-100=5b
2850=5b
2850/5=b
570=b
In ΔPQR, the measure of ∠R=90°, QR = 61 feet, and RP = 90 feet. Find the measure of ∠P to the nearest degree.
Step-by-step explanation:
given= in triangle PQR,<R=90⁰ QR=61 FEET RP=90 FEET
by using pythagoras therom ;
(hypotenuse)²=(side1)² +(side2)²
(PQ)²=(PR)²+(QR)²
(PQ)²=(90)² + (61)²
(PQ)²=8100 + 3721
(PQ)²=11821
TAKING SQUARE ROOTS ON BOTH SIDES, WE GET;
PQ= 108 feet
<P = thita
sin ⁰ = opposite/hypotenuse
sin⁰ =QR/PQ
SIN⁰ =61/108
SIN⁰ =0.56

"For evil to flourish, it only requires good men to do nothing."- Simon Wiesenthal
Simon Wiesenthal is a holocaust surviver. Although many different variations of this quote exists, this provides us a more haunting view of the world. Explain what this quote means. Explain if you agree or disagree with this quote. Finally, explain if you think it is difficult for "good men" to speak up of out? This should be in 3-5 sentences
Answer:
I disagree with this quote. I think this quote means that good men should relax and make the others do the work. I think it could be hard at times for good men should to speak up for a couple of reasons. I think it could be hard for men to speak up because they could be embarrassed or at certain times they wouldn't know what to do so they would freak out. Just because it may be hard to speak up doesn't mean they should be lazy and relax, they should still help in my opinion.

Which equation has the same solution as x^2 - 8x - 15 =3
Answer:
x^2 - 6x -18 is the same so you can write
x^2 - 6x -18 = ( x^2 - 8x - 15 = 3)
Step-by-step explanation:
When we subtract 3 each side we get -18 as -15 -3 is -18
x^2 - 6x -15 = 3
x^2 - 6x -15- 3 =
x^2 - 6x - 18 = 0
When equations equal or set equal to zero we can then use the quadratic formula found in your book.
x1
= −(−8) − √ (−8)2 − 4×1×(−18) / 2×1
= 8 − 2 × √ 34
/2
≈ −1.831
x^2
= −(−8) + √ (−8)2 − 4×1×(−18)
/2×1
= 8 + 2 × √ 34 / 2
≈ 9.831
Ben enters the water during a scuba dive. After 41 seconds of diving, his depth changes by - 29 feet. He wants to know his average change in depth each second. Write an expression for the average change in depth each second.
Answer:
-0.7073ft/sec
Step-by-step explanation:
Given the following
Distance covered by Ben = -29feet
Time taken = 41secs
Required
average change in depth each second(speed)
average change in depth each second = Distance/Time
average change in depth each second = -29/41
average change in depth each second = -0.7073ft/sec
Answer:
The answer is -29 divided by 41

The true statements are:
B. dot plot would show 7 points for numbers greater than 2.
D. histogram would have a maximum of 7 bars.
What is a Dot Plot and a Histogram?A dot plot uses dots to show each data point, while for histogram, the frequency for the data values are depicted by bars or bins.
In the data ste given, 7 of the data points are greater than 2. So, the dot plot for the data distribution would display 7 points for values greater than 2.
Also, there are 7 different values, which are from 0 - 6. This will require 7 bars if we want to represent the data on a histogram.
Therefore, the true statements are:
B. dot plot would show 7 points for numbers greater than 2.
D. histogram would have a maximum of 7 bars.

Calculate the length of side x.
Answer:
30cm
Step-by-step explanation:
Because of the polygon similarity postulate (PSP) 8/12=20/x
8/12=20/x
20/(8/12)=x
20*12/8=x
x=30 cm
The length of side x is 30 cm when the shapes below are mathematically similar.
To calculate the length of side x, we can use the concept of similarity between the shapes. When two shapes are mathematically similar, their corresponding sides are proportional.
8 cm corresponds to 20 cm
12 cm corresponds to x (unknown)
Using the concept of proportionality, we can set up the following equation:
(8 cm) / (20 cm) = (12 cm) / (x)
To find x, we can solve this equation:
Cross-multiplying:
8 cm * x = 20 cm * 12 cm
Simplifying:
8x = 240 cm²
Dividing both sides by 8 to isolate x:
x = 240 cm²/ 8
x = 30 cm
Therefore, the length of side x is 30 cm.

The value of x in the figure is 21.4
How to solve for x?To do this, we make use of the following law of sine
[tex]\frac{\sin (A)}{a} = \frac{\sin (B)}{b}[/tex]
Using the values in the question, we have:
[tex]\frac{\sin (x)}{12} = \frac{\sin (42)}{22}[/tex]
Multiply both sides by 12
[tex]\sin (x) = \frac{12\sin (42)}{22}[/tex]
Evaluate the quotient
[tex]\sin (x) = 0.3650[/tex]
Take the arc sine of both sides
x = 21.4

The length of a rectangle is one less than twice its width. The area is 66 square centimeters. Find the length and width.
Answer:
I. Length, L = 11 cm
II. Width, W = 6 cm
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Area of rectangle = 66 cm²
Translating the word problem into an algebraic expression, we have;
L = 2W - 1 .....equation 1
We know that the area of a rectangle is given by the formula;
A = L * W
Substituting
66 = L * W ....equation 2
Substituting eqn 1 into eqn 2, we have;
66 = (2W - 1) * W
66 = 2W² - W
2W² - W - 66 = 0
Note: the standard form of a quadratic equation is ax² + bx + c = 0
a = 2, b = -1 and c = -66
Solving the quadratic equation using the quadratic formula;
The quadratic equation formula is;
[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]
Substituting into the equation, we have;
[tex] x = \frac {-(-1) \; \pm \sqrt {1^{2} - 4*2*(-66)}}{2*2} [/tex]
[tex] x = \frac {1 \pm \sqrt {1 - (-528)}}{4} [/tex]
[tex] x = \frac {1 \pm \sqrt {1 + 528}}{4} [/tex]
[tex] x = \frac {1 \pm \sqrt {529}}{4} [/tex]
[tex] x = \frac {1 \pm 23}{4} [/tex]
[tex] x_{1} = \frac {1 + 23}{4} [/tex]
[tex] x_{1} = \frac {24}{4} [/tex]
x1 = 6
We do not need the negative value of x, so we proceed.
Therefore, Width, W = x1 = 6 cm
Next, we find the length L;
From eqn 1;
L = 2W - 1
L = 2(6) - 1
L = 12 - 1
L = 11 cm

If you had a sealed bottle of water, how would the mass of
the water bottle change after a 5 day period?
A. mass would increase
B. mass would stay the same
C. mass would decrease
D. none of the above
Using the density concept, it is found that the mass would stay the same, and the correct option is given by B.
-----------------
Density is mass divided by volume, that is:[tex]d = \frac{m}{v}[/tex]
Using the equation, the mass will be given by:[tex]m = dv[/tex]
-----------------
The density of the water is constant, so it would stay the same after 5 days.The bottle will be sealed, thus the amount of water, that is, the volume, will also stay the same.Mass is multiplication of mass and volume, since both stay the same, mass also stays the same, and thus, the correct option is B.A similar problem is given at https://brainly.com/question/16909559
