What is the Answer to: 120 Times 2/3
Answer:
80
Step-by-step explanation:
You could multiply by 2 and then divide by 3
120*2 = 240
240/3 = 80
Or you could divide by 3 and then multiply by 2
120/3 = 40
40*2 = 80
Answer:
80Step-by-step explanation:
120 × 2/3= 120/1 × 2/3= 240/3= 80[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]
Identify the glide reflection rule in the given figure.
Question 8 options:
Translation: (x,y) → (x – 5,y); Reflection across y-axis
Translation: (x,y) → (x,y – 5); Reflection across y-axis
Translation: (x,y) → (x,y + 5); Reflection across y-axis
Translation: (x,y) → (x,y + 5); Reflection across x-axis
Answer:
B
Step-by-step explanation:
The shape clearly is reflected across y axis and the x coordinates remain the same. We can see a change in the y coordinates and the shape has shifted 5 units down. Hence (x, y) -> (x, y-5) and then reflection across y axis is the answer
Answer:
B

I WILL MARK YOU AS BRAINLIEST IF YOU ANSWER THIS QUESTION!!
Answer:
2296 unit^2
Step-by-step explanation:
The area is the sum of the 6 rectangles in the net.
= 38*10 + 38*16 + 38*10 + 38*16 + 10*16 + 10*16
= 380 + 608 + 380 + 608 + 160 + 160
= 2296.
what is
f(x)= (x-12)(x+1)
in standard form?
Answer:
x^2-11x-12
Step-by-step explanation:
I use the box method, which makes a 2x2 box. Then you arrange you numbers based on the equation (show in image)
Then you multiply it out and get the equation
F(x)= x^2+x-12x-12
Simplify your equation and you get
F(x)= x^2-11x-12

Exercise 5
A bag of corn can feed 50 chickens for 12 days.
a) For how many days will the same bag feed 40 chickens?
b) How many bags of corn are needed to feed 20 chickens for 30 days?
2. Fifteen men build a wall in five days. How long will it take the following
number of men to build the wall?
al one man
b) 10 men
c) 20 men
3. A 3-year-old girl has six sisters. Her youngest sister is 4 years old.
a) How many sisters did she have when she was 1 year old?
Answer:
Step-by-step explanation:
a) By proportion number of days = 12 * 50/40
= 15 days.
b) Finding the number of bags per day that 1 chicken needs:
50 chickens eat 1 bag in 12 days
so 50 chickens eat 1/12 of a bag in 1 day.
1 chicken eats 1/(12*50) of a bag in 1 day.
20 chickens for 30 days:
20 chickens eats 20(12*50) in 1 day
and in 30 days 20 eat 30*20 / (12*50)
= 1 bag.
2.
a) 5*15 = 75 days
b) (15/10) * 5 = 7 1/2 days.
c) (15/20) * 5 = 3 * 5 /4 = 3 3/4 days.
3. When she was 1 year old her youngest sister was 2 - she had the same number of sisters as when she was 3.
So the answer is 6.

Hope this helps <3
Please help me solve this fast!
Answer:
base = 18.89
legs = 16.89
Step-by-step explanation:
x + x + 68 = 180
2x + 68 = 180
2x = 112
x = 56
The altitude = 14
Tan(56) = opposite / adjacent
adjacent = base
opposite = altitude
Tan(56) = opposite / base Multiply both sides by the base
base * Tan(56) = opposite Divide by Tan(56)
base = opposite / Tan(56)
base = 14/tan(56)
base = 9.443
The base is actually twice this length because the altitude lands on the midpoint of the opposite side and is perpendicular to the third side (base).
base = 18.886
Legs are the hypotenuse formed by 1/2 the base and the attitude.
Sin(56) = opposite / hypotenuse
Sin(56) = altitude / hypotenuse
hypotenuse = altitude / Sin(56)
hypotenuse = 14 / sin(56)
hypotenuse = 16.887
Rounded
base = 18.89
legs = 16.89
Katie brought 5/6 pounds of candy to a slumber party tori brought 1/3 pound of candy how much candy did the girls have altogether
Answer:
1 [tex]\frac{1}{6}[/tex] pounds of candy
Step-by-step explanation:
Add together the fractions by creating a common denominator of 6:
[tex]\frac{5}{6} + \frac{1}{3}[/tex]
[tex]\frac{5}{6} + \frac{2}{6}[/tex]
= [tex]\frac{7}{6}[/tex]
Simplify into a mixed fraction:
= 1 [tex]\frac{1}{6}[/tex]
So, the girls had 1 [tex]\frac{1}{6}[/tex] pounds of candy

Answer:

Step-by-step explanation:
Solve the simple interest formula, I = Prt, for P. (2 points)
P = Irt
P equals r over i t
P equals i over r t
Answer:
t= i/pr
Step-by-step explanation:
We were given that the amount of simple interest earned is given by the formula, i= prt
The above formula is an example of a literal equation.
We want to solve this formula for T.
But we can observe that the product of two letters are multiplying the letter T.
So we multiply both sides of the literal equation by the reciprocal of PR witch is 1/PR to obtain, I*1/PR=*PRT
This implies that, i/pr=t
We can rewrite this as, t=i/pr
Therefore the correct answer is C.

Answer: Yo-yo
Concept:
In order to find the Cost Per Toy, we need to do the operation Cost / Toy.
Solve:
Slinky = Cost / Toy = 9 / 5 = $1.8 per toy
Wind-up robot = Cost / Toy = 16 / 8 = $2 per toy
Yo-yo = Cost / Toy = 15 / 6 = $2.5 per toy
Emoji beach ball = Cost / Toy = 3 / 2 = $1.5 per toy

For the function y = 3x + 5
what is the output of the
function if the input is 10?
Answer:
[tex]35[/tex]
Step-by-step explanation:
One is given the following function ([tex]y=3x+5[/tex]). The given problem asks one to find the output of the function when the input is (10). Keep in mind, a general rule for dealing with functions is that, when present, the variable (x) represents the input. Whereas the variable (y) represents the output. Thus, if one were to substitute (10) in place of (x), and simplify: the result one would get is the output. Apply this idea to the given scenario:
[tex]y=3x+5[/tex]
[tex]y=3(10)+5[/tex]
[tex]y=30+5[/tex]
[tex]y=35[/tex]
