BARSIC [14]

Answer:

t is between 0.47 seconds and 4.02 seconds

Step-by-step explanation:

Given

$Inequality: -4.9t^2+22t+0.75>10$

Required

Determine the values of t

$-4.9t^2+22t+0.75>10$

Subtract 10 from both sides

$-4.9t^2+22t+0.75 - 10 >10 - 10$

$-4.9t^2+22t-9.25 >0$

Multiply through y -1

$4.9t^2-22t+9.25$

Solve t using quadratic formula:

$t = \frac{-b \±\sqrt{b^2 - 4ac}}{2a}$

Where

$a = 4.9$

$b = -22$

$c = 9.25$

So, we have:

$t = \frac{-(-22) \±\sqrt{(-22)^2 - 4*4.9*9.25}}{2 * 4.9}$

$t = \frac{22 \±\sqrt{484 - 181.3}}{9.8}$

$t = \frac{22 \±\sqrt{302.7}}{9.8}$

$t = \frac{22 \±17.40}{9.8}$

Split the equation

$t = \frac{22 + 17.40}{9.8}$ or $t = \frac{22 - 17.40}{9.8}$

$t = \frac{39.4}{9.8}$ or $t = \frac{4.6}{9.8}$

$t = 4.02$ or $t = 0.47$

Hence; the range is

$0.47 < t$

Shannon is making three different sizes of blankets from the same material. The first measures 2.5 feet by 2 feet. She wants to

Arada [10]

Answer:

<h2>The dimensions of the third blanket are 7.5 feet by 6 feet.</h2><h2>All the blankets are similar.</h2>

Step-by-step explanation:

The size of the first blanket is 2.5 feet by 2 feet.

Shannon wants to enlarge the first blanket by scale factor 2 to make the second blanket.

Hence, the size of the second blanket will be $(2.5\times2) = 5$ feet by $2\times2 = 4$ feet.

Again she enlarged the second blanket by a scale factor 1.5 to make the third blanket.

Hence, the size of the second blanket will be $5\times1.5 = 7.5$ feet by $4\times1.5 = 6$ feet.

Enlargement only changes the size of the blanket, it does not change the shape of the blanket. Hence, all the blankets will be similar.

Please can someone help. ill give brainliest

vodka [1.7K]

Step-by-step explanation:

upper left angle and lower right are the same in a parallelogram (the other two angles match as well, but aren't useful)

so we can write this equation:

3x -15 = 2x +24

1x -15 = 24

x = 39

always do the same thing on both sides of an equation (here: subtract 2x, then add 15)

now you might give it a try yourself with the next problem that got two same things in it.

always grow stronger :)
