Answer:
R=5
Step-by-step explanation:
The area of a semi circle is 1/2(pi×R^2).
Since the area is given you would just work backwards.
Using 3.14 as "pi", you would have
39.25 = 1/2(3.14×R^2)
39.25*2 = 3.14*R^2
78.5 = 3.14* R^2
78.5/3.14 = R^2
25 = R^2
Then you would take the sqrt of R and 25
And the answer would come to 5 = R
R= radius

The points N(-4,3)(−4,3), O(-4,-3)(−4,−3), and P(5,3)(5,3) form a triangle. Plot the points then click the "Graph Triangle" button. Then find the perimeter of the triangle. Round your answer to the nearest tenth if necessary.
The perimeter of the triangle = 25.8 units.
What is the Perimeter of a Triangle?Perimeter = the sum of the length of all three sides
Given:
N(-4,3)
O(-4,-3)
P(5,3)
Perimeter of triangle NOP = NO + OP + NP
Find NO:
NO = |3 - (-3)| = 6 units
Find NP:
NP = |-4 - 5| = 9 units
Using the distance formula, find OP:
OP = 10.8 units
Therefore, Perimeter of the triangle = 10.8 + 9 + 6 = 25.8 units.

5. What is the distance from V to W? V=8 cm W 15 cm m<VW= 90
Answer:
17 cm
Step-by-step explanation:
If the angle between V and W is 90°, then this implies that V and W are legs of a right triangle (and the distance between them is the hypotenuse).
Use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse of a right triangle.
Let D = distance between V and W:
⇒ V² + W² = D²
⇒ 8² + 15² = D²
⇒ 289 = D²
⇒ D = √289
⇒ D = 17
Therefore, the distance from V to W is 17 cm
[tex]\huge \boxed{\sf 17\ cm}[/tex]
Pythagoras discovered that the square of the hypotenuse of a right-angled triangle, where one of the angles is 90 degrees, equals the sum of the squares of the other two sides.

Milo is making 1 1/2 batches of muffins for a bake sell. If each batch of muffins calls for 1 3/4,how many cups of flour will he need ?
Answer:
2 5/8
Step-by-step explanation:
Because she has one whole batch of cookies that will require 1 3/4 of flour. Since the remainder is a 1/2 batch, you would have to half the 1 3/4. Halfing 1 3/4 is 7/8. You add 1 3/4 + 7/8 and you get 2 5/8.

The price for 3 protein bars $3.75, and the price of 3 fruit cups is $1.50. Write the equation
that represents the relationship between the number of protein bars, x, and fruit cups, y,
that you can buy with $15.50.
How many fruit cups can you buy with 4 protein bars?
Answer:
7 fruit cups
Step-by-step explanation:
$3.75/3x + $1.50y = $15.50
So, if you have 4 protein bars, the equation would read:
1.25x + 1.5y = 15.5
1.25(4) + 1.5y = 15.5
5 + 1.5y = 15.5
1.5y = 10.5
y = 7

Answer: A
Step-by-step explanation: πr2 h = 1100 cm³
Here r = 5
(22/7) ⋅ (5)2 ⋅ h = 1100
h = 2/7

Can the sides of a triangle have lengths 7, 12, and 18?
Answer:
Yes
Step-by-step explanation:
By the Triangle Inequality Theorem, if a supposed triangle has sides [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] where [tex]c[/tex] is the longest side, then [tex]a+b\geq c[/tex].
Here, [tex]7+12\geq18[/tex], so the given sides of the triangle can have these lengths

solve: y = 3x - 4
y = x + 2
Answer:
y = 5
Step-by-step explanation:
Isolate x to plug in to other equation
y = x + 2
-y-x -y-x
(- x = -y + 2) / -1
x = y - 2
Plug into other equation
y = 3(y-2) - 4
