Tara's car accelerated from 10 miles per hour to 70 miles per hour in 12 seconds.

1 answer:

3 0

It would be: a = v₂-v₁ / t
a = (70-10) / 12
a = 60 / 12
a = 5 m/s²

So, option A is your final answer.

Hope this helps!

Sue is upholstering a rectangular ottoman that measures 21 centimeters by 18 centimeters by 15 centimeters. What will be the tot

Anika [276]

Answer:

1926cm²

Step-by-step explanation:

Given

Dimension = 21cm by 18cn by 15cm

The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:

$Surface\ Area =2(LB + LH + BH)$

Where L, B and H are the dimensions.

So,

$Surface\ Area = 2(21 * 18 + 21 * 15 + 18 * 15)$

$Surface\ Area = 2(378 + 315 + 270)$

$Surface\ Area = 2(963)$

$Surface\ Area = 2 * 963$

$Surface\ Area = 1926cm\²$

Hence, 1926 cm² of fabrics are needed to cover all surfaces.

Each equation represents a linear relationship. Examine each and determine the slope and y- intercept

marysya [2.9K]

Answer:

Slope is -3/7. Y intercept is 250/7.

Step-by-step explanation:

Since they asking for the slope and y intercept, let put it in slope intercept form.

$y = mx + b$

where m is the slope and b is the y intercept.

The equation given is in standard form so we will convert it to slope intercept.

$3x + 7y = 250$

$7y = 250 - 3x$

$y = \frac{250}{7} - \frac{3}{7} x$

$y = - \frac{3}{7} x + \frac{250}{7}$

The slope is -3/7

The y intercept is 250/7

What is the slope of the line that passes through the points (3,1) and (-2,5)

sweet-ann [11.9K]

The gradient formula is:

m = y2 - y1/ x2 - x1

> m = 5 - 1 /-2 -3
>> m = 4/-5x
