Answer:
The answer is that angle 1 is 70 degrees.
Step-by-step explanation:
Alright so all vertical angles are congruent and the sum of all angles IN and triangle equals 180 degrees. So, the angle on the inside of the top of the triangle is 60 degrees because vertical angles are congruent. Now the angle across from the 130 degree angle is 130 degrees, and we know that the outer and inner angles are supplementary, (add up to 180 degrees) so the angle on the inside is 50 degrees. Then, all angles of a triangle equal 180 degrees therefore, 180-(60+50)= the final angle. Now 70 degrees is the last angle and this angle is vertical to angle 1 which means that angle 1 equals 70 degrees.
Hiroki's goal is to collect $40 for a school fundraiser. He already collected $26.50. Hiroki wants to know how much more money he needs to collect.
Let m be the amount of money Hiroki still needs to collect. Describe the situation with an equation.
Hiroki needs to collect $13.50 more.
What is Algebra?Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. It tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.
As per the given data:
Total amount to be collected = $40
Amount already collected = $26.50
To find the amount of money still to be collected (m):
Total amount to be collected - Amount already collected
= $40 - $26.50
= $13.50
Hence, Hiroki needs to collect $13.50 more.

Answer:
60 cm^3 is the volume
Answer:
132 squared cm
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
A 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

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

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.
