Answer:

angle1= 55

Step-by-step explanation:

180-125=55

(complementary angles

or

angles in a triangle are 180 so

180-(88+37)

180-125

55

Answer is 55 degrees. Literally ‘angles on a straight line’, which is 180 degrees total so if we minus 180 by 125 the we get 55 degrees. You can even cross check the answer by adding all 3 angles: 37+88+55(the angle which you just found) it will altogether add to 180 degrees.

2 feet to 2 yards ratio

vredina [299]

Answer:

$\frac{1}{3}$

Step-by-step explanation:

Three feet make a yard, so 2 yards is 6 feet

$\frac{2}{6}$ If we divide the top (numerator) and the bottom (denominator) by 2 we get

$\frac{2}{6}$ ÷ $\frac{2}{2}$ = $\frac{1}{3}$

PLEASE HELP WITH MATH QUESTION!! EXPLANATION NEEDED TOO!

Dovator [93]

Answer:

Matt should have factored out the leading coefficient 2 on the second step before completing the square

Step-by-step explanation:

To complete the square, you must first factor the leading coefficient from the first two terms.

y = 2x² − 10x − 4

y = 2 (x² − 5x) − 4

y = 2 (x² − 5x + 25/4 − 25/4) − 4

y = 2 (x² − 5x + 25/4) − 25/2 − 4

y = 2 (x − 5/2)² − 33/4

A train 100 m long crosses a pole in 5 seconds.Find the speed of the train in kilometre per hour.

In-s [12.5K]

Answer:

$\sf72 km/h$

Step-by-step explanation:

Distance covered by the train in crossing the pole = 100 m.

$\sf Time \: taken=5 \: seconds$

$\sf \: Speed \: of \: the \: train = \frac{Distance }{Time}$

$\sf = \frac{100}{5} \: m/s$

$\sf \: = 20 \: m/s$

$\sf \: = 20 \times \frac{18}{5} \: km/h$

$\sf = 72 \: km/h$

Hence, the speed of the train is 72 km/h

I've been on vacation this week and my math teacher just gave me a packet of makeup work to do. a lot of them are questions like

adelina 88 [10]

To visualize better, look at it like this:

$\frac{3r^3}{2r}$

First, see if you can simplify 3/2. You can't, so leave it like that.

The rule for exponents is you subtract the exponent from the bottom (r) from the exponent on the top ( $r^3$ )

$r^3 - r^1 = r^2$

Put that on the top, and you get

$\frac{3r^2}{2}$
