Hailey used 2 2/3 liters of cola to completely fill 2 bottles. If the bottles are all the same size, how many liters of cola does each bottle hold? Enter your answer below
Answer:
they each hold 1 1/3 litters of cola
Step-by-step explanation:
Because if there is 2 2/3 liters of cola
then you either divide it by 2
or you can look at it and see what would add evenly to make that number
in this case it would be 1 1/3
1 1/3 +1 1/3= 2 2/3

Sum of interior angles in the triangle is 180°.
Sum of the angles of the given triangle:
(2x + 8) + (5x) + 74 = 180Solve for x:
2x + 8 + 5x + 74 = 1807x + 82 = 1807x = 98x = 14A groundskeeper needs grass seed to cover a circular field, 290 feet in diameter.
A store sells 50-pound bags of grass seed. one pound of grass seed covers about 400 square feet of field.
What is the size of the field in square feet, to the nearest whole?
Answer:
66018.5 sq feet
Step-by-step explanation:
Area = πr²
To find the Radius R we need Diameter which 290 fee so:
R = Diameter / 2
R = 290/2
R = 145 ft
Now put values in Area Formula
Area = 3.14 x (145)^2
A = 66018.5 sq feet
What is the volume, in cubic centimeters, of a cylinder with a height of 12 centimeters and a base radius of 6 centimeters, to the nearest tenths place?
Please help :(
Answer:
1357.2
Step-by-step explanation:
volume = r^2 * pi * h
= 6^2 * pi * 12
=432pi
The volume of cylinder is 1357.17 cubic centimeter.
Formula to find the volume of cylinder:V = base area × height
[tex]V=\pi \times r^{2} \times h[/tex], where r is the radius of circular base and h is the height of the cylinder.
For given example:
a base radius (r) = 6 cm,
a height of a cylinder (h) = 12 cm
Using the formula of volume of a cylinder,
[tex]V=\pi \times 6^{2} \times 12[/tex]
[tex]V=1357.17[/tex] cubic cm
Hence, the volume of a cylinder is 1357.17 cubic centimeter.

Step-by-step explanation:
Alright so assuming the this is a right angle, to find the area of a triangle you have to multiply LxW and divide by 2. 3x4=12/2=6. There are 2 triangles, so 6x2=12
And then to find the area of the rectangle on the bottom, 10x4=40
Next you find the area of the rectangle on the side: 3x10=30
And finally the one that’s slanted on the top: 5x10=50
Add them up and 12+40+30+50= 132
Can a triangle have three acute angles? Justify your answer.
brainliest
Answer: Yes!
Step-by-step explanation:
Not only can a triangle have three acute angles (which is very common), you can also get triangles with angles so acute that their total sum is less than 180 degrees! This happens in a 'negative curved space'.
Answer:
Yes It can!
Step-by-step explanation:
If it has 3 acute angles it means it is an acute triangle!

Answer:
Mr. Crosgrove tipped $3.84.
120 pens are not red pens.
She had to pay $270 in taxes.
Step-by-step explanation:
So, to find the percentage of something you convert the percentage to a decimal and then multiply.
For #1
He spent $48, and tipped 8%
to turn 8% into a decimal you bring in down two place values, so it is 0.08. You multiply 48 * 0.08 and you get 3.84.
Mr. Crosgrove tipped $3.84.
For #2
He has 150 flair pens and 20% are red. Multiply 150 by 0.2. You will get 30. Now we know that there is 30 red pens, but the problem is asking how much is not red pens. subtract 150-30 and you get 120, so that is the answer.
120 pens are not red pens.
For #3
She has $2,000 and had to pay 13.5% You have to turn 13.5% into decimal so bring place value down by two so it is now 0.135. Multiply 2,000*0.135 and you get 270.
She had to pay $270 in taxes.
