Cade and Tyce both tried to find the missing side of the right triangle.
A right triangle is shown. The legs are labeled 6 and 9. A right angle is labeled in between them.
Cade's Work Tyce's Work
a2 + b2 = c2 a2 + b2 = c2
62 + b2 = 92 62 + 92 = c2
36 + b2 = 81 36 + 81 = c2
b2 = 45 117 = c2
Square root b squared equals square root 45. Square root 117 equals c squared.
b ≈ 6.71 10.82 ≈ c
Is either of them correct? Explain your reasoning.
Answer: a2 + b2 = c2 a2 + b2 = c2 is correct
Step-by-step explanation:
reason being:
if a2 and b2 are in the equation that would make c2 a2 rational and when the number is rational thats automatically easy to know the area and square root and thats the key! the questions states the spuare root and area which makes it all easy to know that the correct one is a2 + b2 = c2 a2 + b2 = c2.
(Hopes this helps)
Step-by-step explanation:
Answer:
Tyce is correct because you are finding the hyphenous and not the missing side.
Step-by-step explanation:
I also did the work to double check and I got the same answer as Tyce.

Answer:
Real numbers are all the rational numbers such as -7 and 4/3 and all irrational numbers. Real numbers are used mainly in counting and are used in measurement which is always present in real-world situations. These numbers help us to quantify things around.
Find the volume of the figure
Answer:
A = 189.25
Step-by-step explanation:
A = πr²
15 x 10 = 150
5 x 5 x 3.14 = 78.5
78/2 = 39.25
You divide by 2 because it's half of a circle.
150 + 39.25 = 189.25

Find S7of the sum of the geometric series.a1=−4374,a7=−6,r=1/3
Group of answer choices
A. −6568
B. −6583
C. −6563
D. −6534
Answer:
The sum of the first 7 terms in the geometric sequence is -6558
Step-by-step explanation:
s7 refers to the sum of the first 7 terms of the geometric sequence
To calculate the sum of terms, we use the sum of terms formula
We have this generally given as;
Sn = a(1-r^n)/(1-r)
a refers to the first term, given as a1 which is -4374
r is the common ratio which is 1/3
n is the number of terms, which is 7
substituting these values;
s7 = -4374(1-(1/3)^7)/(1-1/3)
s7 = -4374(1-(1/3)^7)/2/3
s7 = (3 * -4374)/2 * (1- (1/3)^7
s7 = -6561 * (1-1/2187)
s7 = -6561 * (2187-1)/2187
= -6561 * 2186/2187
= -6558

Answer:
your answer will be 25 .....ok
Answer:
x = 25
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 15
3 = 15k ( divide both sides by 15 )
[tex]\frac{3}{15}[/tex] = k, that is k = [tex]\frac{1}{5}[/tex]
y = [tex]\frac{1}{5}[/tex] x ← equation of variation
When y = 5 , then
5 = [tex]\frac{1}{5}[/tex]x ( multiply both sides by 5 to clear the fraction )
25 = x

can someone help with the two triangle questions (will mark brainliest!!)
Answer: Number 1 is c=89 ft
Number 2 is b=3 cm
Step-by-step explanation: a²+b²=c²
For number 1, 39 ft is a and 80 ft is b so
39²+80²=c² so 39² is 39x39=1521 and 80² is 80x80=6400 so 6400+1521=7921
7921=c² and the square root of 7921 is 89 so c=89 ft
For number 2, a=1.6 cm and c=3.4 cm so 3.4²-1.6²=b²
3.4² so 3.4x3.4 which is 11.56
1.6² so 1.6x1.6 which is 2.56
11.56-2.56=c² and 11.56-2.56=9
Square root of 9 is 3 so b=3
So number 2 answer is b=3 cm

Melissa is saving $25 that she earned for washing her mom's car. She earns $10 every week
for doing chores, which she also saves.
Which function can be used to find t, the amount of money Melissa will have saved at the end
of 'n weeks of doing chores?
Answer:
25+ 10n= t
Step-by-step explanation:
you already have 25. Then you get $10 each week, which is 10n.
Parallel lines never intersect, therefore, there is one solution
Answer:
Step-by-step explanation:
If parallel lines don't intersect, then there can't be any solutions. An intersection represents a solution.

Answer:
x = 9
Step-by-step explanation:
By the property of intersecting secants:

john is twice as old as his son. his son is 5 years older than his sister . in five years to come John will be 3 times as old as his daughter. how old is his son now?
Answer:
5
Step-by-step explanation:
Terrible wording on the question as the "father" is 15 the "son" is 10 and the sister is 0 or just born
J = john
S = son
X = sister
J = 2s
S = 5 + X
3(x+5) = J + 5
J = 2(5+x) = 2x + 10
3x+15 = 2x +10 + 5
x = 0
A bookshelf has 36 fiction books and 44 non-fiction books. What percentage of the total books are non-fiction?
Answer:

A dartboard has a diameter of 30 inches. What are its radius and circumference?
Answer:
radius = 15 in.
circumference = 94.2 in.
Step-by-step explanation:
radius = diameter/2 = 30 in./2 = 15 in.
circumference = (pi)d = 3.14 * 30 in. = 94.2 in.
Mr. Yasin paid a total of 9.43 to buy three boxes of cereal. If he paid 3.99 for the 1st box and 2.97 for the 2nd box how much did Mr. Yasin pay for third box of cereal?
$4.72, 2.47, 6.96, or 3.54
Answer:
$2.47
Step-by-step explanation:
Pretend if Mr. Yasin didn't pay for the 3rd box, find out how much he had left after paying for the first 2 boxes.
9.43 - 3.99 - 2.97 = 2.47

Solve the system using elimination.
y=-x-3
y=x2-15
Answer:
X=4, y=-7
Step-by-step explanation:
To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2
2(y)=2(-x-3)
2y=-2x-6
——————
add above equation 2y=-2x-6
to second equation Y=2x-15
add together. 3y=-21
Y=-7
—————————————-
solve for x by substituting y value (7) into either equation
y=-x-3
-7=-x-3
-4=-x
4=x

2. What is the product of column B?
What is the product of column C?
Answer:
1. -5
2. -24
3. 0
Step-by-step explanation:
Sum means addition.
Product means multiplication.
A negative times a negative will give you a positive.
Anything times zero is zero.
1. -2 + 5 + (-8) = -5
2. -1 * -4 * -6 = -24
3. 10 * 0 *-9 = 0
