Applying the Pythagorean theorem, Find the measure of the missing side of a right triangle if one leg is 7 cm and the hypotenuse is 25 cm.
Answer:
24
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
7^2 + b^2 = 25^2
49 + b^2 = 625
Subtract 49 from each side
49+b^2 -49 = 625-49
b^2 = 576
Take the square root of each side
sqrt(b^2) = sqrt(576)
b = 24
Step-by-step explanation:
[tex]hypotenuse {}^{2} \: = base {}^{2} + \: perpendicular {}^{2} \: \\ \\ base {}^{2} = 25 {}^{2} - 7 {}^{2} \\ \\ base {}^{2} = 625 - 49 \\ \\ base {}^{2} = 576 \\ \\ base = \sqrt{576} \\ \\ base = 24 \\ \\ [/tex]

Step 1: Find the slant height
10^2 + 28^2 = c^2
884 = c^2
c = [tex]\sqrt{884}[/tex]
Step 2: Find the lateral area
LA = pi * radius * slant height
LA = pi * 10 * [tex]\sqrt{884}[/tex]
LA (rounded to the nearest tenth) = 297.3pi in^2
Step 3: Find the area of the base circle
A = pi * r^2
A = pi * 10^2
A = 100pi in^2
Step 4: Add the areas together
SA = 297.3pi + 100pi
SA = 397.3pi in^2
Hope this helps!! :)

One type of candy mix contains 30% Smarties by mass. A second type contains 20% Smarties by
mass. What mass of the 30% mix is required to make a 500 gram mixture that will have 24%
Smarties by mass?
Answer:
200 grams
Step-by-step explanation:
Let us represent
The number of grams of
30% smarties = x
20% smarties = y
Hence:
x + y = 500
x = 500 - y
Hence:
30% × x + 20% × y = 24% × 500
0.3x + 0.2y = 120
Substitute 500 - y for x
Hence:
0.3(500 - y) + 0.2y = 120
150 - 0.3y + 0.2y = 120
Collect like terms
- 0.3y + 0.2y = 120 - 150
- 0.1y = -30
y = -30/0.1
y = 300
Solving for x
x = 500 - y
x = 500 - 300
x = 200
Hence,
The number of grams of
30% smarties = x = 200 grams
20% smarties = y = 300 grams
Therefore:
the mass of the 30% mix is required to make a 500 gram mixture that will have 24% Smarties by mass is 200 grams
what is the vertex of this quadratic?
Answer:
vertex = (3, 2 )
Step-by-step explanation:
The vertex is the turning point of the graph.
This occurs at (3, 2 ) ← vertex
Answer:
The vertex is at (3, 2)
Step-by-step explanation:
Hello!
VertexThe vertex of a parabola is the point of turning, or the minimum/maximum point of the parabola.
Since the graph opens up, the vertex is at the minimum point.
The y-value is 2, and the x-value is 3, giving us the vertex of (3, 2)
Other PartsThere are other parts to parabola than just the vertex.
Standard form of a quadratic: [tex]ax^2 + bx + c[/tex]
Other parts include:
Axis of Symmetry, the line where the parabola is exactly symmetrical, and when folded in half, the sides will match. It is found using the formula [tex]-\frac{b}{2a}[/tex]X-intercepts, also known as the roots or zeroes of the graph, is where the graph touches the x-axis. It is found using the quadratic formula:[tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex]Y-intercepts, the point where the graph hits the y-axis. It is the "b" value in the equation.Click on the graph below to create a quadrilateral with vertices at the following points

What is the probability of drawing a red marble?
2/5
45%
1/3
9/11
Answer:
45%
Step-by-step explanation:
Counting the marbles, there are 5 green, 6 blue and 9 red.
Which means the odds of drawing a red to a non red are 11:9
In fraction form that would be 9 marbles out of 20 are red. 9/20
Since the fraction cannot be simplified, we can go to decimal form.
9/20=.45
.45=45%
The answer is 45%.
Answer:
45%
Step-by-step explanation:
Total = 20
Red = 9
9/20 = 0.45
Therefore 45 % is the correct option :))

Answer:
A and F
Step-by-step explanation:
Given
Intersecting lines
Required
The vertical and congruent angles
The two vertical lines are not parallel. So, we cannot conclude any relationship between angles A, B, E, F and angles C, D, H, G
Comparing angles A, B, E and F; we have:
[tex]\angle A = \angle F[/tex] --- Vertical opposite angles
[tex]\angle B = \angle E[/tex] --- Vertical opposite angles
From the given options,
[tex]\angle A = \angle F[/tex] is true

Answer:
p = 4n
p = 312 passengers
n = 19.5 cars
Step-by-step explanation:
Let
n = number of cars
p = number of passengers
a. p = 4n
b. p = 4n
Find p if n = 78
p = 4n
p = 4 * 78
p = 312 passengers
c. Find n if p = 78
p = 4n
78 = 4n
Divide both sides by 4
78 / 4 = 4n / 4
19.5 = n
n = 19.5 cars
The value of a home is $899,000 and increasing in value at a rate of 1% per year. Use an exponential growth function to find the approximate value of the home in 12 years.
Answer:
$1012993.2
Step-by-step explanation:
Given data
Cost of home V= $899,000
Rate of increase= 1%
Time= 12 years
The exponential growth function is expressed as
A=V(1+r)^t
A=899000(1+0.01)^12
A= 899000(1.01)^12
A= 899000*1.1268
A=$1012993.2
Hence the cost of the home will be $1012993.2

Answer:

Step-by-step explanation:
I don't really know how to show the steps, but one of the easiest ways to do this is to see how many times 0.8 goes into 3.2. So 0.8 + 0.8 + 0.8 +0.8 = 3.2 So 3.2/0.8 is 4
Or you can multiply the numerator and denominator by 10, which keeps the value of the fraction but gets rid of pesky decimals: 32/8 this should be fairly straight forward and a key reason to memorize your times tables. 8*4=32
