Answer:

It is 40 degrees.

Step-by-step explanation:

You can start off by understanding this is not a right angle (exactly 90 degrees, think of a corner of a room) or and obtuse angle (more than 90 degrees, bigger than a right angle). With that information we know that it is an acute angle (less than 90 degrees, smaller than a right angle). With that we have 40 and 50 degrees left. When you compare the angle with the 40 degrees one, it is the same size. The angle 1 is a reflection of the triangle with the 40 degrees angle. Hope this helps :)

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 26 feet a

Setler [38]

Answer:

3183.96 ft^3

Step-by-step explanation:

let pi = 3.14

volume of a cylinder is base * height

find the base: (area of circle)

height is given

container A:

circle area = 530.66

multiply 530.66 by the height (13)

530.66 * 13 = 6898.58

container B:

circle area = 530.66

multiple 530.66 by the height (19)

530.66 * 19 = 10082.54

Find empty space:

10082.54-6898.58 = 3183.96

At a school, 60% of the sixth-grade students said that pizza is their favorite kind food. If 210 sixth-grade students prefer piz

Vika [28.1K]

Answer:

350

Step-by-step explanation:

Let $s=$ total number of sixth-grade students.

It is given that 60% of sixth-grade students prefer pizza which is equivalent to 210 sixth-grade students. With this, the following can be written:

$60\%s = 210$

$0.6s=210$ ( $60\%$ can be converted into the decimal form $0.6$ )

$s = 210\div 0.6$

$=350$

∴ There is a total of 350 sixth-grade students in the school.

Hope this helps :)

Please help, (AP is arithemtic progression)

defon

Answer:

p = 8

Step-by-step explanation:

The n th term of an AP is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₉ = 4 + 5p and d = 5, then

a₁ + 8d = 4 + 5p, that is

a₁ + 8(5) = 4 + 5p

a₁ + 40 = 4 + 5p ( subtract 40 from both sides )

a₁ = 5p - 36

a₂ = 5p - 36 + 5 = 5p - 31

a₃ = 5p - 31 + 5 = 5p - 26

a₄ = 5p - 26 + 5 = 5p - 21

Given that the sum of the first 4 terms = 7p - 10, then

5p - 36 + 5p - 31 + 5p - 26 + 5p - 21 = 7p - 10, that is

20p - 114 = 7p - 10 ( subtract 7p from both sides )

13p - 114 = - 10 ( add 114 to both sides )

13p = 104 ( divide both sides by 13 )

p = 8
