Answer: Hello there!

First, i think that the equation given is 1.6x10^2

Now we need to find a number that is three hundred thousand bigger than this:

This is 300,000 times 1.6x10^2 or 300000*1.6x10^2 = (3x10^5)*(1.6x10^2) = (3*1.6)x10^(5 + 2) = 4.8x10^7

then the number 4.8x10^7 is three hundred thousand times larger than 1.6*102.

First solve the equation
so 163.2
then multiply by 3000
so 489600

Masteriza [31]

Answer:

320 cups of soup

Step-by-step explanation:

2/5= x/800

2/5 =.04

800*.04 =320 x=320

2/5 = 320/800

2/5 =0.4 is equivalent to 320/800=0.4

One fourth the sum of x and ten is identical to x minus 4."

Lynna [10]

Answer and Step-by-step explanation:

We are given the word format of an equation.

Let's right it out in numerical form.

$\frac{1}{4} (x + 10) = x - 4$

The first part says One fourth the sum of x and 10

The sum of x and 10 would be shown as x + 10, and one fourth of that means that $\frac{1}{4}$ is multiplying (x + 10).

In this case, identical would mean equal to.

So, $\frac{1}{4}$ (x + 10) would be = to something.

It says that it is identical to x minus 4 (x - 4).

$\frac{1}{4} (x + 10) = x - 4$ is the equation.

Use the discriminant to describe the roots of each equation. Then select the best description.

Paha777 [63]

The quadratic equation 3 · x² + 7 · x - 2 = 0 has a positive discriminant. Thus, the expression has two distinct real roots (real and irrational roots).

<h3>How to determine the characteristics of the roots of a quadratic equation by discriminant</h3>

Herein we have a quadratic equation of the form a · x² + b · x + c = 0, whose discriminant is:

d = b² - 4 · a · c (1)

There are three possibilities:

d < 0 - conjugated complex roots.
d = 0 - equal real roots (real and rational root).
d > 0 - different real roots (real and irrational root).

If we know that a = 3, b = 7 and c = - 2, then the discriminant is:

d = 7² - 4 · (3) · (- 2)

d = 49 + 24

d = 73

Find the measure of CP

dmitriy555 [2]

Given:

A figure ABCP.

To find:

The measure of CP.

Solution:

In triangles ABP and CBP,

$\angle PAB\cong \angle PCB$ (Given right angles)

$\angle ABP\cong \angle CBP$ (Given)

$BP=BP$ (Common side)

Now,

$\Delta ABP\cong \Delta CBP$ (By AAS property of congruence)

We know that the corresponding parts of congruent triangles are congruent.

$AP=CP$

$8=CP$

Therefore, the measure of CP is 8 units.

A sports store received a shipment of 150 footballs and basketballs. 20% were basketballs. How many footballs were in the shipme

RideAnS [48]

0.20(150) = 30 basketballs were in the shipment. Since the shipment presumably comprised only footballs and basketballs, the remainder of the shipment must consist of footballs.

150 - 30 = 120 footballs were in the shipment.
