Find the area of the triangle.

Ne4ueva [31]

Answer:

10.92cm

Step-by-step explanation:

We can solve this problem by taking the formula to the area of a triangle and substituting our given numbers with the variables in it.

$A = \frac{1}{2}bh$ , where $b$ represents base and $h$ represents height.

So, if we substitute our given measurements with the variables in this formula, we can easily solve this.

$A = \frac{1}{2}(2.8)(7.8)$

Then, using the order of operations, we multiply and ultimately solve this problem.

$\frac{1}{2}*2.8 = 1.4$

$1.4*7.8=10.92$

Thus, our answer is 10.92cm.

Fifteen more than twice the hours Carla worked last week is the same as three times the hours she worked this week decreased by

lapo4ka [179]

2x-15=3(x-15)
2x-15=3x-45
2x+30=3x
30=x

Let's check this work!

2(30)-15=3(30-15)
60-15=3(15)
45=45

She worked 45 hours each week

*the reason it is 2x-15 and not 15+2x is because "more than" is considered a "turn around word" meaning it is the opposite

The weight of an object on the moon is 1/6 of its weight on earth. If a moon rock weighs 20 1/2 lb on earth, how much did the ro

Pie

Step-by-step explanation:

20 1/2 = (20×2 + 1)/2 = 41/2.

to create 1/6 of that we have to multiply it by 1/6 :

41/2 × 1/6 = 41/12 = 3 5/12

the rock weighed 3 5/12 lb.

Pls help asap so confused!!!!<br><br> What is the distance??

Vesnalui [34]

Answer:

6.3

Step-by-step explanation:

You can find the distance with a distance formula (need the points and it has a big, long square root) BUT, when you have an image like this graph you can totally see a right triangle and use the Pythagorean Theorem (distance formula is derived from Pythagorean theorem anyway) see image
