1 math question in 1/200 second

2 minutes have 2×60 seconds = 120 seconds.

each of the seconds has 200 1/200 seconds.

so, in 2 minutes we have

120 × 200 time units to finish math questions.

in each time unit 1 math question can be answered.

120×200 = 24,000

the computer can answer 24,000 math questions in 2 minutes.

2.

it can run for 15 minutes.

15 minutes have

15×60 = 900 seconds (as every minute has 60 seconds)

it can vacuum 1/2 ft² in 1 seconds.

in 900 seconds it can then vacuum 900×1/2 = 450 ft².

so, yes, it can clean 400 ft² without recharging.

a farmer grew 8,914 bushels of corn. he delivered corn to different stores using his truck. his truck can carry 336 bushels of corn in one load. what was the least number of loads the farmer made to deliver all the corn to the stores?

Answers

Answer:

The farmer had to do 27 loads.

Step-by-step explanation:

Basically the easy way to do this is to grab a calculator (or the paper and pen way) and keep adding 336 until you get to 8914.

Once you add it all you will see there is a remainder of his corn left (that has not been delivered):178

Even though it isn't a full 336, the farmer would still have to make another trip.

336*26=8,736

So, adding the remainder into it's own load, we would get:

We determine the scale factor by comparing the lengths of corresponding sides of the square.

The length of O’N’=15 and the length of the corresponding segment ON =9.
Then, we compute the scale factor:
O’N’=kON

k=15/9=5/3.

The scale factor is k=5/3.

b^2=48, how do you answer a question like this? (also the words have nothing to do with the equation, i'm just confused)

Answers

The solution of the equation b² = 48 is b = 4√3

How to solve equation?

The equation can be solved as follows;

b² = 48

Therefore, we are to find the value of b in the equation.

The value of b comes with a square sign, so we have to remove the square to make b stand alone in the equation.

By removing the square sign we have to square root both sides.

Hence,

b² = 48

square root both sides of the equation

b² = 48

√b² = √48

Therefore,

b = √16 × 3

b = 4√3

Line EF is the bisector of angle BAC

How are a compass and straightedge used to construct geometric figures?

Geometric figures are constructed using a compass and a straightedge, by using outlined steps or procedures.

From the diagram, given that the circumference of the circle with center B passes through the center of the circle with center D, and vice versa, we have;

Circle B is congruent to circle D

Construction of Perpendicular Bisector to Line BD

The steps to construct a perpendicular bisector to the segment BD includes;

Placing the compass at point B and draw an arc above and below segment BC then place the compass at point D then draw arcs above and below the segment BD to intersect the previous arcs drawn from point B. at points E and FJoin the point of intersection of the two arcs which are the points E and F to complete the the construction of the perpendicular bisector of segment BD

Therefore;

Line EF is the perpendicular bisector of segment BD

Shen invested in a savings bond for 6 years and was paid simple interest at an annual rate of 3% . the total interest that he earned was $1620 . how much did he invest?

Answers

The principal amount invested by Shen in the saving bond is $9,000.

What is explained as the simple interest?Simple interest is a simple and fast method to calculate the interest on a loan. Simple interest is calculated by multiplying this same daily interest rate even by principal multiplied by the amount of days between payments.

As per the given question;

The formula for simple interest is-

SI = PRT/100

Principal be 'P'Simple Interest SI = $1620.Time t = 6 yearsRate of interest R = 3%.

Put the values;

SI = PRT/100, write the formula in the terms of P

P = 100×SI/RT

P =  100×1620 / (3×6)

On simplification;

P = 9,000

Thus, the amount invested by Shen in the saving bond is $9,000.

3) The value of x is 10

4) The slope of the line is; 2

How to Interpret rule of transformation?

1) The rule of transformation for When the point M (h, k) is rotated through 90° clockwise about the origin, the point M (h, k) takes the image M' (k, -h). Thus, that is the rule here.

2) From the given image, we can tell that the angles 50° and 26x - 2 are corresponding angles. Thus, they are congruent and we have;

26x - 2 = 50

26x = 52

x = 2

3) From the given image, we can see that the given angles are supplementary and as such they add up to 180 degrees. Thus;

9x + 15 + 6x + 15 = 180

15x + 30 = 180

15x = 150

x = 10
