70 thousand in word form would be seventy thousand, but in standard it would be just numbers 70,000

Neither, since standard form is the number form which would be 70,000 and the word form would be seventy thousand.

Whose experiment correctly represents the relationship shown at the table

Troyanec [42]

c: number of carnations

r: number of roses

Rebecca's expression is

r = c + 4

Replacing with the values of the table:

c | r

0 | 0+4 = 4

1 | 1+ 4 = 5

2 | 2+4 = 6

3 | 3+4 = 7

4 | 4+4 = 8

Then, Rebecca is correct.

Isolating c from Rebecca's expression:

c = r - 4

which is Austin's expression. Then, Austin is correct too.

A circle has an area between 100-150 square inches,what are some possible lengths for a diameter of this circle

Ulleksa [173]

Answer:

it would range between 11.28379... to 13.819765...

Step-by-step explanation:

the circle's area formula is pi * radius^2

so you make to equation, plugging the 100 and 150 into the circle's area

you get square root of (100/pi) which gets 11.28379... for the area of 100

you do the same with 150 to get square root of (150/pi) which gets 13.819765...

those are the diameter of the circle since the diameter is double the radius which i already multiplied afterwards. so if you need the radius divide the number ive given you

A painter is going to apply a special coating to a triangular metal plate on a new building. Two sides

viva [34]

Answer:

$Area = 90.03cm^2$

Step-by-step explanation:

Given

$s_1 = 14.9$

$s_2 = 14.7$

$\theta = 124$ --- angle in between

Required

The area of the plate

Since $\theta = 124$ is between $s_1$ and $s_2$

The area is:

$Area = \frac{1}{2} * s_1 * s_2 * \sin(\theta)$

$Area = \frac{1}{2} * 14.9 * 14.7 * \sin(124.7)$

$Area = \frac{1}{2} * 14.9 * 14.7 * 0.8221$

$Area = 90.03cm^2$

Find the mean, median, mode, and range for each of the following sets of numbers

Sidana [21]

Answer:

The mean - $45\dfrac{2}{7};$ the median - 35, the mode - 27, the range - 47.

Step-by-step explanation:

Arrange the set of data (31,74,27,58,65,27,35) in ascending order:

27, 27, 31, 35, 58, 65, 74.

The mean is the usual average, so add aal numbers and then divide by the number of numbers:

$\dfrac{27+27+31+35+58+65+74}{7}=\dfrac{317}{7}=45\dfrac{2}{7}.$

The median is the middle value. The middle value in the row 27, 27, 31, 35, 58, 65, 74 is 35.

The mode is the number that is repeated more often than any other, so 27 is the mode.

The largest value in the set is 74, and the smallest is 27, so the range is 74 – 27 = 47.
