What is the hypotenuse of 2 meters and 4 meters?
Answer:
[tex]\sqrt{20\\}[/tex]
Step-by-step explanation:
a^2 +b^2=c^2
c is the hypotenuse
assuming that 2 is a and 4 is b, then it would be:
2^2 + 4^2= c^2
4+16=c^2
20=c^2
take the square root of both sides
[tex]\sqrt{20}=\sqrt{c^{2} }[/tex]
c=[tex]\sqrt{20}[/tex]

2(x + 31.5) = 3x + 24
Answer:
2(x + 31.5) = 3x + 24
2x+63= 3x+24
2x+63-63=3x+24-63
x=39
Answer:
[tex]x=39[/tex]
Step-by-step explanation:
[tex]2\left(x+31.5\right)=3x+24[/tex]
[tex]\textbf{Apply the distributive law:-}[/tex]
[tex]a(b+c)=ab+ac[/tex]
here, a= 2, b=x, c= 31.5
[tex]2\left(x+31.5\right)[/tex]
[tex]\textbf{Multiple:-}[/tex] [tex]2\cdot \:31.5=63[/tex]
[tex]=2x+63[/tex]
[tex]2x+63=3x+24[/tex]
[tex]\textbf{Now, Subtract 63 from both sides:-}[/tex]
[tex]2x+63-63=3x+24-63[/tex]
[tex]2x=3x-39[/tex]
[tex]\textbf{\mathrm{Subtract\:}3x\mathrm{\:from\:both\:sides}:-}[/tex]
[tex]2x-3x=3x-39-3x[/tex]
[tex]-x=-39[/tex]
[tex]\textbf{\mathrm{Divide\:both\:sides\:by\:}-1:-}[/tex]
[tex]\frac{-x}{-1}=\frac{-39}{-1}[/tex]
[tex]x=39[/tex]

You deposit $2000 in an account that earns simple interest at an annual rate of 4%. How long must you leave the money in the account to earn $500 in interest?
Answer:
6.25YEARS
Step-by-step explanation:
S.I.=P×R×T÷100
T=S.I.×100÷P×R
T=500×100÷2000×4
T=500÷20×4
T=500÷80
T=6.25 YEARS
Karla bought a student discount card The card cost $6 and allows her to buy each meal for $3 after one week Karla spent $15 how many meals did she buy ?
Answer:
3 meals
Step-by-step explanation:
The card costs $6, so we will subtract that from $15 because it is the starting amount. Karla can't buy these meals for $3 without $6. Anyways, 15-6 is 9. Each meal costs $3 so we'll then divide 9 by 3, which gives us our answer: she bought 3 meals.
Answer:
Karla bought 3 meals.
Step-by-step explanation:
6+3m=15
Subtract 6 both sides.
3m=9
Divide 3 both sides.
m=3
m=meals she bought

What is the decimal equivalent of 6/13 ? Round to tenths place. If answer doesn't
have a tenths place then use zero on the end to make the answer have a tenths place
to be counted correct.
Answer:
0.5
Step-by-step explanation:
6/13 is the same as saying 6 ÷ 13
6 ÷ 13 = 0.4615384615
The first position after the decimal is the tenths column. Round up, because 6>5.

is the answer 24 or 80 please I don't know explain with steps nad explanations pls
Answer:
≈ 8.9
Step-by-step explanation:
Assuming you are requiring the length of the unknown side
let the side ( hypotenuse ) be x
Using Pythagoras' identity
The square on the hypotenuse ie equal to the sum of the squares on the other 2 sides, that is
x² = 4² + 8² = 16 + 64 = 80 ( take square root of both sides )
x = [tex]\sqrt{80}[/tex] ≈ 8.9 ( to 1 dec. place )

Answer:
x = -3
Step-by-step explanation:
To find and solve the value for x
