Round 1,384 to the nearest thousand and round 2,332 to the nearest hundred

Mathematics

1,384 rounded to the nearest thousand would be 1,000 because when you look at the hundreds place, there is a 3 and the rule is, if it’s under 5 round down but if it’s over 5 (or if it is 5) you round up.
2,332 rounded to the nearest hundred would be 2,300 because once again there was a number less than 5 before it so we rounded down.
I hope this helped! Have a wonderful day! :-)

The ratio of the measures of three angles is 3:8:9. find the measure of each angle of the triangle.
MAXImum [283]

To solve this problem you must apply the proccedure shown below:

1. You have that the ratio of the measures of the three angles is 3:8:9

2. The sum of the interior angle of a triangle is 180degrees

3. Let's say that the measure of each angle is x multiplied by the ratio. Therefore, you can write the following equation and solve for x:

3x+8x+9x=180\\ x=9

4. Therefore, the measure of each angle is:

3(9)=27degrees\\ 8(9)=72degrees\\ 9(9)=81degrees

The answer is: 27degrees, 72degrees,81degrees

Write as an equation: Sara spent $2 more than Lauren, and together they spent $19.
kupik [55]

Answer:

Equations:

a + b = 19

a = b + 2

a = Money that spent Laura

b = Money that spent Laureen

then:

(b+2) + b = 19

2b + 2 = 19

2b = 19-2

2b = 17

b = 17/2

b = 8.5

a = b + 2

a = 8.5 + 2

a = 10.5

Check:

10.5 + 8.5 = 19

The linear relationship represented by the table has an initial value of 88 and a rate of change -6. Complete the table.
Nimfa-mama [501]
(2,88)
(6,64)
(9,46)
(15,10)
first find y=mx+b
88=-6(2)+b
b=100
y=-6x+100
then plug for y and solve for x or vise versa.

<u>Question:</u>

Find the number of real number solutions for the equation. x^2 + 5x + 7 = 0

<u>Answer:</u>

The number of real solutions for the equation x^{2}+5 x+7=0 is zero

<u>Solution:</u>

For a Quadratic Equation of form : a x^{2}+b x+c=0  ---- eqn 1

The solution is x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}  

Now , the given Quadratic Equation is x^{2}+5 x+7=0  ---- eqn 2

On comparing Equation (1) and Equation(2), we get

a = 1 , b = 5 and c = 7

In x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a} , b^2 - 4ac is called the discriminant of the quadratic equation

Its value determines the nature of roots

Now, here are the rules with discriminants:

1) D > 0; there are 2 real solutions in the equation

2) D = 0; there is 1 real solution in the equation

3) D < 0; there are no real solutions in the equation

Now let solve for given equation

D= b^2 - 4ac\\\\D = 5^2 - 4(1)(7)\\\\D = 25 - 28 \\\\D = -3

Since -3 is less than 0, this means that there are 0 real solutions in this equation.
