Step-by-step explanation:
in probability,or means addition.
14/28+19/28
1/2+19/28
you then find the LCM of the denominator.
14+19/28
33/28
you then divide 33 by 28.
The radius of a circle is 8 feet. What is the circle's area?
Use 3.14 for .
Answer:
50.27
Step-by-step explanation:
remember that the circumference of a circle is 2πr
so 3.15x8 and then multiply by two
Answer:
200.96 ft²
Step-by-step explanation:
Step 1: Define/formula
To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.
[tex]a=\pi r^2(3.14*radius*radius)[/tex]
Step 2: Solve
According to the word problem, the radius is 8.
From here, we plug the numbers into the formula.
[tex]\pi 8^2(3.14*8*8)=200.96ft^2.[/tex]
Step 3: Conclude
Therefore, the area of this circle is 200.96 ft.²

The number 44 is multiplied by a 44-digit number that contains only ones. What is the sum of the digits of the product?
Answer:
352.
Step-by-step explanation:
The product will have 45 digits, the fisrt and last digit will be 4 and the middle 43 will be 8.
So the sum = 2*4 + 43*8
= 352.
What 2 sides need to be congruent in order to prove the 2 triangles are congruent by HL?
PLEASE HELP ASAP!
Answer:
The two hypotenuses.
Step-by-step explanation:
HL or Hypotenuse-Leg Theorem: two right triangles are congruent if and only if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of the other right triangle.
Since we already know the bottom leg of each triangle is congruent, we only need to know the two hypotenuses.

A right triangle has a hypotenuse measuring 15
inches and one leg measuring 9 inches. What is the
length, in inches, of the other leg of the triangle?
A 3
B 6
C 10
D 12
Answer:
D
Step-by-step explanation:
15^2 = 9^2 + x^2
x^2 = 15^2 -9^2
x^2 = 225-81
x^2 = 144
x = 12

Homemade applesauce is one of Duncan's favorite foods, so he bought 10 pounds of apples at the farmers' market. His applesauce recipe says that 8 ounces of apples make 1 cup of applesauce. How many cups of applesauce can he make with 10 pounds of apples?
Answer:
20 cups of applesauce
Step-by-step explanation:
8 ounces = 0.5 pounds
Pounds of apples : cups of applesauce
0.5 pounds : 1 cup = 10 pounds : x cups
0.5/1 = 10/x
0.5*x = 1*10
0.5x = 10
x = 10/0.5
x = 20 cups of applesauce
10 pounds of apples will make 20 cups of applesauce
answer please no linkd or files
the answer is F
or x=3

Answer:
z = 113
y = 31
Step-by-step explanation:
j || n and line a is their transversal. (given)
Therefore,
z° = 180° - 67° (exterior angles on the same side of transversal)
z°= 113°
z = 113
(5y - 88)° = 67° (exterior alternate angles)
5y - 88 = 67
5y = 67 + 88
5y = 155
y = 155/5
y = 31
HELP!!! Simplify cos^2 0 -1/ 4sin^2 0?
We need to simpify the given expression. The given expression to us is ,
Given Expression :-
[tex]\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta }[/tex]
Using Identity :-
[tex]\sf\implies \red{ sin^2\theta + cos^2\theta = 1}[/tex]
So that :-
[tex]\sf\implies - sin^2\theta = cos^2\theta -1[/tex]
We have :-
[tex]\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta } \\\\\sf\implies\dfrac{ - sin^2\theta}{4sin^2\theta}=\boxed{\sf -\dfrac{1}{4}} [/tex]
Hence the required answer is -1/4.

A student needs 15 minutes to solve an algebra problem. How many minutes does the student need to solve 5 problems?
it's easy, you only need to divide 15 by 5.
Like this :
15÷5= 3
• because 5×3 = 15 , so you just need to flip it over
so, the student need 3 minutes to solve 5 problems

Answer:
1 and -3
Step-by-step explanation:
To solve for the roots (x-1)(x+3) set x-1 to = 0 and solve for x. Same thing for x+3.
Answer:
1, and -3
Step-by-step explanation:
So when looking for roots, we take our quadratic equation that is in factored form, and set each partheasese to 0:
x-1=0 and x+3=0
Now just subtract and add the -1 and +3 to both sides:
x=1 and x=-3
These are your 2 answers for the quadratic.

Find the hypotenuse of a right triangle if the legs are 22 and 26. Round to nearest hundredth
Answer:
Step-by-step explanation:
length of Legs of the right angle triangle = 22 (unit) and 26 (unit)
To find the length of hypotenuse of the right angle triangle, we have to use Pythagoras property
Lets keep hypotenuse as "h" and one leg as "a" and another as "b"
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]h^{2}[/tex]
[tex]22^{2}[/tex] + [tex]26^{2}[/tex] = [tex]h^{2}[/tex]
484 + 676 = [tex]h^{2}[/tex]
[tex]h^{2}[/tex] = 1,160
h = [tex]\sqrt{1,160}[/tex]
h = 34.05 (unit)

please help me answer this question-
Answer:
[tex] \displaystyle GH = 2 \sqrt{30} [/tex]
[tex] \displaystyle FH = 2 \sqrt{10} [/tex]
[tex] \displaystyle m \angle G = {30}^{ \circ} [/tex]
Step-by-step explanation:
QUESTION-2:we are given a right angle triangle
it's a 30-60-90 triangle of which FH is the shortest side
remember that,in case of 30-60-90 triangle the the longest side is twice as much as the shortest side thus
our equation is
[tex] \displaystyle 2FH=4\sqrt{10}[/tex]
divide both sides by 2
[tex] \displaystyle\frac{2FH}{2}= \frac{ 4 \sqrt{10} }{2}[/tex]
[tex] \displaystyle FH =2 \sqrt{10}[/tex]
Question-1:in order to figure out GH we can use Trigonometry because the given triangle is a right angle triangle
as we want to figure out GH we'll use sin function
remember that,
[tex] \displaystyle \sin( \theta) = \frac{opp}{hypo} [/tex]
let our opp, hypo and [tex]\theta[/tex] be GH, 4√10 and 60° respectively
thus substitute:
[tex] \displaystyle \sin( {60}^{ \circ} ) = \frac{GH}{4 \sqrt{10} } [/tex]
recall unit circle:
[tex] \displaystyle \frac{ \sqrt{3} }{2} = \frac{GH}{4 \sqrt{10} } [/tex]
cross multiplication:
[tex] \displaystyle 2 GH = 4 \sqrt{10} \times \sqrt{3} [/tex]
simplify multiplication:
[tex] \displaystyle 2 GH = 4 \sqrt{30} [/tex]
divide both sides by 2:
[tex] \displaystyle GH = 2 \sqrt{30} [/tex]
QUESTION-3:Recall that, the sum of the interior angles of a triangle is 180°
therefore,
[tex] \displaystyle m \angle G + {60}^{ \circ} + {90}^{ \circ} = {180}^{ \circ} [/tex]
simplify addition:
[tex] \displaystyle m \angle G + {150}^{ \circ} = {180}^{ \circ} [/tex]
cancel 150° from both sides
[tex] \displaystyle m \angle G = {30}^{ \circ} [/tex]

What is the radius of the circle?
Answer:
8×ED=3×15
ED=45/8
the radius is the half of the diameter
so its 45/16
