7 0

Use the area formula and solve for the height.

A = 1/2 (b)(h)

46 = 1/2 (10.1)(x)
46 = 5.05x
46/5.05 = x
9.1 = x

The height is 9.1

Hope this helps :)

I might be wrong but try 46 divided by 10.1?

Is 4(4a+20b) equivalent to 16a+24b

No.

When you are distributing, you are multiplying to each monomial

4(4a) = 16a

4(20b) = 80b

16a + 80b is your actual answer

NEED HELP WITH A MATH QUESTION

Answer:

$\dfrac{18}{5}$

Step-by-step explanation:

The picture shows three isosceles tirangles with the same legs. The base of each triangle is 12 units, 5x-3 units and 17 units.

Since the angles at vertex of each isosceles triangles are 27°, 28° and 29°, then the lengths of the bases satisfy the double inequality

15<5x-3<17

Add 3 to this inequality

15+3<5x-3+3<17+3

18<5x<20

Divide it by 5:

$\dfrac{18}{5}$

Jim is selling hot dogs at a ball game. It cost Jim $250 to purchase everything to make the hot dogs. Jim sells hot dogs for $2.

Olegator [25]

So since he is wasting money to purchase everything you won't be gaining but loosing so 250-2h= P bc it's $2 for every hot dog and you are losing again

Maurinko [17]

Answer:

45 apps

Step-by-step explanation:

1 minute has 60 seconds

If 12 seconds equals to 9 apps

60 seconds equals to x apps

Cross multiplying

$x=\frac {60\times 9}{12}=45 apps$

Therefore, Dean downloads 45 apps in 1 minute
