What is the best estimate for the product 289 and 7? Make it clear to understand : )

1 answer:

4 0

Hey friend!
Let's figure this out!

The best estimate for the product 289 and 7 is 2,900.

290 x 10 = 2,900.

You must round the multiplicand and multiplier to come up with the best estimate.

Hope this helps!

a honey bee gathered nectar for 3/4 of an hour. it returned to the hive every 1/12 hour. how many trips did the bee make ?

alekssr [168]

Divide.

3/4 / 1/12

Flip the 2nd fraction and multiply:

3/4 * 12/1

Multiply the numerators and denominators together:

36/4

Divide:

9

So the bee made 9 trips.

Bill can paint a small house in 3 days, Sharon can paint a small house in 4 days and Wilber can paint a small house in 5 days. H

Paraphin [41]

To solve this problem, let us say that the action of totally painting a small house is called “1 job”. Therefore the rates of each person in painting the small house are:

Bill = 1 job / 3 days = 1 / 3

Sharon = 1 job / 4 days = 1 / 4

Wilber = 1 job / 5 days = 1 / 5

Therefore the total rate is calculated by simply adding the rates of the three.

(1 / 3) + (1 / 4) + (1 / 5) = 1 / x

where x is the number of hours it take if all them paint together

Calculating for by multiplying both sides by 60:

60 [(1 / 3) + (1 / 4) + (1 / 5) = 1 / x]

(60/3) + (60/4) + (60/5) = 60 / x

20 + 15 + 12 = 60 / x

47 = 60 / x

x = 60 / 47 hours

Answer:

60/47 hours

Write the point-slope form of the line that passes through (5,5) and is perpendicular to a line with a slope of 1/4 include all

amid [387]

<u>Answer:</u>

The point-slope form of the line that passes through (5,5) and is perpendicular to a line with a slope of $\frac{1}{4}$ is 4x + y -25 = 0

<u>Solution:</u>

The point slope form of the line that passes through the points $\left(x_{1} y_{1}\right)$ and perpendicular to the line with a slope of “m” is given as

$\bold{y-y_{1}=-\frac{1}{m}\left(x-x_{1}\right)}$ ---- eqn 1

Where “m” is the slope of the line. $x_{1} \text { and } y_{1}$ are the points that passes through the line.

From question, given that slope “m” = $\frac{1}{4}$

Given that the line passes through the points (5,5).Hence we get

$x_{1}=5 ; y_{1}=5$

By substituting the values in eqn 1 , we get the point slope form of the line which is perpendicular to the line having slope $\frac{1}{4}$ can be found out.

y - 5 = -4(x - 5)

y - 5 = -4x + 20

on simplifying the above equation, we get

y - 5 + 4x -20 = 0

4x + y - 25 = 0

hence the point slope form of given line is 4x + y - 25 = 0

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $1790 and his st

stiv31 [10]

Answer:

20.7%

Step-by-step explanation:

Amount of stock increased in Company A = 20% of 1790

= 0.20 * 1790 = $ 358

Investor's stock in company A this year = 1790 + 358 = $ 2148

Amount of stock increased in Company B = 22% of 1000

= 0.22 * 1000= $ 220

Investor's stock in company B this year = 1000 + 220 = $ 1220

Total amount in investor's stock account = 2148 + 1220 = $ 3368

Increased amount = 3368 - 2790 = $ 578

Increase percentage = $\frac{578}{2790}*100$ = 20.71

= 20.7%
