Answer:

The angle is 90 degrees

Step-by-step explanation:

Required

Angle subtended by the diameter

The theorem to solve this is:

The angle subtended by an arc is twice the angle it subtends.

The diameter forms [tex]180^\circ[/tex] on the circle, so we have:

[tex]2*\theta = 180^\circ[/tex]

Where [tex]\theta[/tex] is the angle subtended

Solve for [tex]\thets[/tex][tex]\theta[/tex]

[tex]\theta = \frac{180^\circ}{2}[/tex]

[tex]\theta = 90^\circ[/tex]

Answer:

2 hours, 4 hours

Step-by-step explanation:

So lets go over what we know.

There are already 10 worksheets created.

Every 1 hour 3 more are made.

27 worksheets need to be made.

Ok, the first thing we can do is subtract the amount of worksheets needed by the amount we laready have:

27-10

=

17

Now, lets divide the amount of worksheets we still need, by how many we make each hour:

17/3

=

Well, 3 goes into 15, 5 times. Then 2 is left. So we know it takes 5 2/3 hours to create all 27 worksheets.

Looking at the answers, 6 hours, 8 hours, and 10 hours would work. However 2 hours and 4 hours would not work.

Hope this helps! ;)

Answer:

it looks like the answer to this problem is $280.

Step-by-step explanation:

i got this answer because you add $100 and $250 together. You will get $350. Then you take 20% of that total. So, 20% of 350 is 70. Now take 350-70, which = 280. and that should be your final answer.

Answer:

1.75

Step-by-step explanation:

h(t) = -16t² + 56t

h'(t) = -32t + 56

To find time at max height equate h' to 0

0 = -32t + 56

t = 56/32 = 1.75 s

It takes 1.75 s to reach max highest point

Hello! Answer: 496

Step-by-step explanation:

When finding area for triangles we have to do base x height then divide by 2 so

62 x 16 = 992

992 ÷ 2 = 496

So 496 is our answer!

Answer:

A - 496

Step-by-step explanation:

formula for area of a triangle

[tex]a = \frac{bh}{2} [/tex]

where b = base length and h = height

The triangle shown has a base length of 62 ft and a height of 16 ft

That being said we plug in the given values into the formula

[tex]a = \frac{62 \times 16}{2} \\ 62 \times 16 = 992 \\ \frac{992}{2} = 496[/tex]

Hence the area of the triangle is 496 square feet

brainliest pwease??

The volume of a cylinder can be found with the following equation

[tex]V = r^2h\pi[/tex]

After inputting the known information we get

[tex]980\pi = r^220\pi \\\\[/tex]

Which simplifies to

radius = 7 or (-7)

For proof's sake, we can try the equation again with the known radius

[tex]980\pi = r^220\pi \\980\pi = (7^2)20\pi \\980\pi = (49)20\pi \\980\pi = 980\pi \\[/tex]

And because the radius is being squared, it can either be negative or positive.

Answer:

0

Step-by-step explanation:

find mean : 2+3+4+7 divided by 4 equals 4

subtaract mean from valuses: 2-4= -2 , 3-4= -1 , 4-4= 0 , 7-4= 3 ,

find mean with new numbers: -2+-1+3+0 divided by 4 equals 0 (everything cancels out)

630

Answer:

789 to nearest whole number.

Step-by-step explanation:

In 4 years its increased from 220 to 350.

350 = 220(e)^4k  where k is some constant.

e^4k = 350/220

4k = ln (350/220) = 0.4643

k = 0.1161

The equation  of growth is therefore

P = 220e^0.1161t)

So  in 2011 ( t = 11 years) the

Population = 220 * e^(11*0.1161)

= 789.

Answer:

167.36 weeks

Step-by-step explanation:

Given: Currently has $180, the cost is $860, and he plans to save $68 a week

To find: How many weeks will it take to save his money

Solution: If Barry currently has $180 and needs $860 for his tires also saves $68 a week, divide the amount he wants to save by the amount he saves a week, to find how many weeks will it take to save his money

                                          860 ÷ 68 = 12.64

Subtract 180 because he already has $180 saved currently

                                           180 - 12.64 = 167.36

Hence, it will take approximately 167 weeks to save his money up to $860

so, vertical is when two different numbers are congruent and adjacent is numbers next to each other but are no congruent

Answer:

40 hours

Step-by-step explanation:

Time=Distance/Speed

Time=1800/45

Time=40 hrs

Answer:

[tex]40h[/tex]

Step-by-step explanation:

[tex]speed = \frac{distance}{time} \\ time = \frac{d}{s} \\ = \frac{1800km}{45kmh ^{ - 1} } \\ = 40h[/tex]

Answer:

Please check explanations

Step-by-step explanation:

To find the volume of the surface area of a cone, we need to use the height and not the slant height of the cone

The slant height, the height and the base radius forms a right triangle with the slant height being the hypotenuse of this triangle

By Pythagoras’ theorem, the square of the hypotenuse (slant height) equals the sum of the squares of the two other sides

6.5^2 = 2.5^2 + h^2

h^2 = 36

h = √36

h = 6 cm

So we have the volume as;

V = 1/3 * pi * r^2 * h

where r in this case is base radius of 2.5 cm

V = 1/3 * pi * 2.5^2 * 6 = 39.3 cm^3
