Not direct answer but

this is how I think

radius = 4 so AC is also 4

You can find with this

2π ( 4 ) ( 51°/360°) = Answer

Actually I am lazy to calculate (◔‿◔)

Megan hiked 15.12 miles in 6.3 hours. If Megan hiked the same number of miles each hour , how many miles did she hike each hour?

OLEGan [10]

To find how many miles per hour, we divide the number of miles hiked by the number of hours it took to hike them.

=15.12 miles ÷ 6.3 hours
=2.4 miles hiked per hour

Hope this helps! :)

Base=30cm<br> Heights=20cm <br> Find the X?

Leviafan [203]

Answer: 25

Assuming the dotted line touches the middle of the base of the triangle,

Using Pythagoras Theorem,

(30/2)^2 + (20)^2 = x^2

x^2 = (15)^2 + 400

x^2 = 625

x = √625 or -(√625)

x = 25 or -25

But since x needs to be a positive value,

x = 25

Answer:

$\boxed {\boxed {\sf (5g^2+2)(2g-5)}}$

Step-by-step explanation:

We are given the expression:

$10g^3-25g^2+4g-10$

There are no common factors between the four numbers, however the first two have a common factor and the last two do too. Therefore, we can factor by grouping.

Group the first two terms and the last two.

$(10g^3-25g^2)+(4g-10)$

Find the greatest common factor (GCF) of the first group. It is 5g². Factor it out of the first group. You can do this by dividing both terms by the GCF.
