Round 922 to the nearest hundred

artcher [175]

900 because just like rounding tens if you have 14 to 11 itll round to 10 if it is from 15-19 youll round to 20. so since 922 isnt 950-999 youll round it to 900

Alfonso leans a 20 ft ladder long against the wall with a base of 6 feet from the wall. How far up the wall does the ladder reac

jolli1 [7]

Answer:

19.1 ft

Step-by-step explanation:

-This a Pythagorean theorem problem given by the function:

$b^2+h^2=H^2$

Where

H is the Hypotenuse length

h is the perpendicular height

b is the base length.

#Given that H=20 ft and base length,b =6 ft, the perpendicular height is calculated as:

$h^2+b^2=H^2\\\\h^2=H^2-b^2\\\\h^2=20^2-6^2=364\\\\h=\sqrt{364}\\\\=19.0788\approx 19.08\ ft$ $\approx 19.1 \ ft$

Hence, the ladder reaches the wall at a height of 19.1 ft

What is an equation of the line that passes through the points (-2, -7) and (-1, -3)?

valentina_108 [34]

Answer:

y = 4x + 1

Step-by-step explanation:

Find slope, rise over run

$\frac{y_{2}-y_{1} }{x_{2}-x_{1}} = \frac{-3--7}{-1--2} = \frac{4}{1} = 4$

find y intercept by plugging in one of the coordinates in y=mx+b, including m=4

-7 = 4(-2) + b

1 = b

almond37 [142]

Answer:

What percent of the school are girls? 55%

What percent of the school are boys? 45%

How many boys are there? 162

How many girls are there? 198

Step-by-step explanation:

The number of girls = 198

The percent of girls = 198/360 x 100% = 55%

The number of boys = 360-198 = 162.

The percent of boys = 162/360 x 100% = 45%.
