In the following number, which place value does the 3 hold? 993,140 hundreds thousands ten thousands hundred thousands

natita [175]

Is 250 basically in 50 but the percentage of the 100 is 50% of the hundred right does that mean in this question it would have to be 250 is half of 300

At what point does the graph of y=9x(x is exponent) cross the y-axis?

uysha [10]

Answer:

-The graph crosses the y-axis at the point (0,0)

None of the given options is correct

A graph crosses the y-axis at the point (0,y).This means that the graph will cross the y-axis when x-=0

To find the point where the graph crosses the y-axis,substitute x=0 into the given equation y-9x

substitute x=0 into the equation y-9x to find the corresponding value of y

That is,

y=9(0)

y=0

therefore the graph crosses the y-axis at the point (0,0)

You want to build a wheelchair ramp leading up to your house. Your front door is 2 feet higher than the driveway and you would l

Alenkasestr [34]

Answer: (a) The angle the ramp forms with the driveway, s° = 4.004° (3 d.p)

(b) The driveway has to be, s = 28.57 ft

(c) The ramp will be 28.64 ft long

Step-by-step explanation:

First key thing to know is that the %grade of a ramp = rise/ramp run

%grade of a ramp = 7% = 0.07

(Kindly find attached a diagram to assist with understanding).

Also note that, the ramp run is not the same as the ramp length

(a) the angle, θ, is the angle of slope between the driveway and the ramp,

tan θ = 0.07,

θ = tan⁻¹ 0.07 = 4.004° (3 d.p)

(b) the length of the driveway (s) is the same as the length of the ramp run, so, %grade of a ramp = rise/ramp run

0.07 = 2/s

s = 2/0.07 = 28.57 ft (2 d.p)

(c) the length of the ramp can be found by using Pythagoras' theorem,

L = ramp length = $\sqrt{rise^{2} + ramprun^{2} }$

L = $\sqrt{2^{2} +28.571^{2} }$

L = $\sqrt{820.3041}$

L = 28.64 ft (2 d.p)

Which of the following is the most appropriate unit to describe the rate at which a person reads?

koban [17]

Answer:

C. Words per minute, because the independent quantity is the minutes.

Step-by-step explanation:

The speed will be measured in words per minute as the number of words a person can read in a minute are counted.

The independent quantities are those quantities which are controlled during the measurement while the dependent quantities change depending on the independent quantities. While measuring the reading speed of a person minute is controlled while the number of words are counted in a minute. So minute is the independent quantity.
