Answer:

m=-\frac{10}{4}

m=-\frac{5}{2}

-\frac{5}{4}+m=-\frac{15}{4}

m+2=-0.5

Step-by-step explanation:

Given equation,

\frac{3}{4}+m=-\frac{7}{4}

\implies m = -\frac{7}{4}-\frac{3}{4}=\frac{-7-3}{4}=-\frac{10}{4}=-\frac{5}{2},

Since, \frac{10}{4}\neq -\frac{5}{2}

\frac{11}{4}+m = -\frac{1}{4}

\implies m = -\frac{1}{4}-\frac{11}{4}=\frac{-1-11}{4}=-\frac{12}{4}=-3\neq -\frac{5}{2}

-\frac{5}{4}+m=-\frac{15}{4}\implies m = -\frac{15}{4}+\frac{5}{4}=\frac{-15+5}{4}=-\frac{10}{4}

m+2=-0.5\implies m = -0.5-2\implies m = -2.5=-\frac{5}{2}

Answer:

The correct choices are; B,C,E, and F.

Step-by-step explanation:

The given equation is;

\frac{3}{4}+m=-\frac{7}{4}

We solve for m to obtain:

m=-\frac{7}{4}-\frac{3}{4}=-2.5

We also solve the remaining equations to see which ones give the same result.

A: m=\frac{10}{4} =2.5

B:m=-\frac{10}{4} =-2.5

C:m=-\frac{5}{2} =-2.5

D: \frac{11}{4}+m=-\frac{1}{4}

m=-\frac{1}{4}-\frac{11}{4}=-3

E: -\frac{5}{4}+m=-\frac{15}{4}

m=-\frac{15}{4}+\frac{5}{4}=-2.5

F: m+2=-0.5

m=-0.5-2=-2.5

The equivalent equations are; B,C,E, and F.

Eight friends are going bowling together if they each rent a pair of bowling shoes for $2.00, they each play two
Mnenie [13.5K]

2.00+1.50= 3.50.

3.50x8= 28.00

I'm assuming they each paid 41.00 dollars for two games,

41.00x8= 328.00

328.00+28.00= $356.00

Hope this is correct and/or it helps!

Sorry, didn't realize my mistake.

From a point T on a horizontal ground, the angle of
grin007 [14]

Answer:

distance TS ≈ 19 m (nearest meter)

Step-by-step explanation:

The point T is on the horizontal ground and the angle of elevation of the top R of a tower is 63° and the height of the tower is 38 m high. The illustration forms  a right angle triangle. The height RS of the tower is the opposite side of the triangle formed. The hypotenuse side of the triangle is the point from the ground T to the top of the tower R.  The adjacent side of the triangle is the side TS.

using tangential ratio

tan 63° = opposite/adjacent

tan 63° = 38/adjacent

cross multiply

adjacent tan 63° = 38

divide both sides by tan 63°

adjacent side = 38/tan 63°

adjacent side = 38/1.96261050551

adjacent side = 19.3619670807

distance TS ≈ 19 m (nearest meter)

school teacher and needs 22 pieces of wood, 3 over 8 ft long, for a class project. If he has a 9-ft board from which to cut the
tiny-mole [99]

Answer:

Yes, he will have enough 3 over 8 ft pieces for his class.

Step-by-step explanation:

Given:

Number of wood required = 22

Length of each wood, l=\frac{3}{8}\textrm{ ft}

Total length of the board, L=9\textrm{ ft}

Therefore, the number of woods that can be made using the given board is given as:

\textrm{Number of woods made}=\frac{\textrm{Total length of board}}{\textrm{Length of each wood}}\\\textrm{Number of woods made}=\frac{L}{l}=\frac{9}{\frac{3}{8}}=9\times \frac{8}{3}=\frac{72}{3}=24

So, he can make 24 woods of length \frac{3}{8}\textrm{ ft} using the 9 ft board. But he has to make only 22 pieces.

Therefore, he has enough of the wood to make the required number of pieces.
