Answer: 127.795 in^2
Step-by-step explanation:
The area of any triangle is [tex]\frac{1}{2} \cdot \text{base} \cdot \text{height}[/tex][tex]\frac{1}{2} \cdot \text{base} \cdot \text{height}[/tex]
The surface of this pyramid is composed of three slanted triangles and the base.
Area of slanted sides (3 of them):
The base of each is 6.1 -- the sides of the bottom triangle all have the same length. The height of a slanted side is 12.2 .
Area of one slanted side is .5(6.1)(12.2) = 37.21
There are 3 identical sides, so the area of all 3 is 3 x 37.21 = 111.63 .
Area of the pyramid's base:
The base of that triangle is 6.1, and its height is 5.3, so its area is
.5(6.1)(5.3) = 16.165
The total area of all four faces is 111.63 + 16.165 = 127.795

1. find 15% of 120
2. what percent of 72 is 68.4
3. 12.5 is 8% of what number?
4. 48 is 40% of what number
5. what number is 62.5% of 195
Answers
1% = 120 ÷ 100 = 1.2
15% = 1.2 × 15 = 18
So, 15% of 120 is 18
For question 2:
68.4 ÷ 72 = 0.95
0.95 × 100 = 95%
So, the percentage is 95%
For question 3,
1% = 12.5 ÷ 8 = 1.5625
100% = 1.5625 × 100 = 156.25
So, 8% of 12.5 is 156.25.
For question 4,
1% = 48 ÷ 40 = 1.2
100% = 1.2 × 100 = 120
So, 40% of 48 is 120.
For question 5,
1% = 195 ÷ 100 = 1.95
62.5% = 1.95 × 62.5 = 121.875
So, 62.5% of 195 is 121.875
Answer:
1. 18 3. 52 5. 95%
Step-by-step explanation:
1. 120 x 0.15= 18.00 (15% of 120 is 18)
3. 84 x 0.03= 2.52
5. 72• x / 72 = 68.4/ 72
x=0.95 ⇒ 95%

Convert the equation below to slope-intercept form
6x+ 8y = -32
Answers
Answer:
y = -3/4x - 4
Step-by-step explanation:
Convert the equation to slope intercept form by isolating y
6x + 8y = -32
Subtract 6x from both sides
8y = -6x - 32
Divide each side by 8
y = -6/8x - 4
Simplify -6/8 to -3/4
y = -3/4x - 4
So, the equation in slope intercept form is y = -3/4x - 4

Find the distance between the two points rounding to the nearest tenth
(if necessary).
(-7, -6) and (-3,2)
Submit Answer
Answer:
Answers
Answer:
8.9
Step-by-step explanation:
To solve this problem you just use the distance equation which is √((x1-x2)^2+(y1-y2)^2). It does not matter which point you use where but if you use -7 as your x1, you have to use -6 as your x1.
The process should look like this
√(-7-(-3))^2+(-6-2)^2)
√((-4)^2+(-8)^2)
√(16+64)
√(80)
=8.944 or 8.9 rounded to the nearest tenth

Answer:
∡ a = 80°
Step-by-step explanation:
the sum of the interior angles of a triangle is 180 degrees
a + 30 + 70 = 180
a + 100 = 180
a = 80
Answer:
80 Degrees
Step-by-step explanation:
A triangle equals 180 degrees when all sides are added together, so here we need to first add the angles of the ones we have available.
30 + 70 = 100
Now, we subtract to find out how much more we need...
180 - 100 = 80
In a geometric sequence, the first term is 3 and the common ratio is 2. What is the sum of the first 9 terms?
a .99
b. 1022
c. 1533
d. 765
Answers
Step-by-step explanation:
99 is the answer........
The sum of the first 9 terms of the given GP series will be 1533 thus option (c ) is correct.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
Let's say the first term of the given GP is a and the common ratio is r.
a = 3 and r = 2
The Sum of n term is given as,
S = a([tex]r^{n}[/tex] - 1) / (r - 1)
S₉ = [3(2⁹ - 1)/(2 - 1)]
S₉ = 1533
Hence "The sum of the first 9 terms of the given GP series will be 1533".

An athlete ran 10 times around the circular track shown below. Approximately how many meters did the athlete run?
Answers
Answer:
Step-by-step explanation:
Since the picture isn't given. I have no idea what the radius or diameter is and as such, have no definite answer for you.
However, from the question, if he's to run round the circular track once, then he must have run a total of
2πr meters, with r being the radius.
Now, the question says that he ran round the track 10 times, this means that whatever value we get there, for 1 trial, we multiply it by 10, to get the value for 10 trials. Essentially,
10 * 2πr
The value gotten is the needed answer. All you have to do is substitute r for the value you have in your diagram. We already know that π is 3.142
3. In a thunderstorm, the wind velocity in meters per second can be described by the function
v(p)=5.7998−p‾‾‾‾‾‾‾√,
where
p
is the air pressure in millibars. What is the air pressure of a thunderstorm in which the wind velocity is 49.3 meters per second? Round your answer to the nearest tenth of a millibar.
Answers
Answer:
p = 923.2 millibar
Step-by-step explanation:
Given that,
The wind velocity can be described by the function as follows :
[tex]v(p)=5.7\sqrt{998-p}[/tex]
Where
p is the air pressure in millibar
Put v = 49.3 m/s in the above function.
[tex]49.3=5.7\sqrt{998-p}[/tex]
Squaring both sides,
[tex]49.3^2=(5.7\sqrt{998-p})^2\\\\2430.49=32.49(998-p)\\\\\dfrac{2430.49}{32.49}=(998-p)\\\\74.80=(998-p)\\\\p=998-74.80\\\\p=923.2\ mbar[/tex]
So, the required pressure is equal to 923.2 millibar.
