Solve the quadratic inequality
4x^2-25<0

Answers

I hope it helps you ❤️❤️❤️❤️

The solution to the inequality, 4x^2 - 25 < 0 is determined as x < 5/2.

Solution to the inequality

The solution to the inequality is obtained by solving the inequality as shown below;

4x^2 - 25 < 0

add 25 to both sides of the equation;

4x² < 25

divide both sides by 4

x² < 25/4

take square root of both sides

x < 5/2

Thus, the solution to the inequality, 4x^2 - 25 < 0 is determined as x < 5/2.

Answer:

For right angle triangle,

we use Pythagoras theorem that is:

[tex]c^{2} =a^{2} +b^{2}[/tex]

c = [tex]\sqrt{a^{2} +b^{2} }[/tex]

For question 1:

c = ?

a = 40

b = 9

putting them in formula,

c = [tex]\sqrt{40^{2} + 9^{2} }[/tex]

c = 41

For question 2:

c = ?

a = 12

b = 13

putting them in formula,

c = [tex]\sqrt{12^{2} + 13^{2} }[/tex]

c = approximately 17.69181

For question 3:

c = 35

a = 20

b = ?

putting them in formula,

[tex]c^{2} =a^{2} +b^{2}[/tex]

[tex]35^{2} = 20^{2} + b^{2}[/tex]

1225 = 400 + [tex]b^{2}[/tex]

[tex]b^{2}[/tex] = 1225 - 400

[tex]b^{2}[/tex] = 825

[tex]\sqrt{b^{2} } = \sqrt{825}[/tex]

b = 5 [tex]\sqrt{33}[/tex]

For question 4:

c = 37

a = 20

b = ?

putting them in formula,

[tex]c^{2} =a^{2} +b^{2}[/tex]

[tex]37^{2} = 20^{2} + b^{2}[/tex]

1369 = 400 + [tex]b^{2}[/tex]

[tex]b^{2}[/tex] = 1369 - 400

[tex]b^{2}[/tex] = 969

Taking square root on both sides

b = 31.12

Find the probability of rolling a 5 or 6 on a fair dice

Answers

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

[tex]\frac{1}{6}[/tex] +  [tex]\frac{1}{6}[/tex]

This is because there is only one "5" and one "6" in a dice. Moreover the total number of numbers in a dice are 6 so the denominator will be 6. Then when the word 'or' is present it means that both the probabilities must be added.

P (of rolling a 5 or 6 on a fair dice) = [tex]\frac{1}{6}[/tex] +  [tex]\frac{1}{6}[/tex]

[tex]\frac{2}{6}[/tex] can be simplified further. Both 2 and 6 are factors of 2 so..

[tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]

P (of rolling a 5 or 6 on a fair dice) = [tex]\frac{1}{3}[/tex]

Leila needs to buy plastic spoons. Brand A has a box of 25 spoons for $1.97. Brand B has a box of 48 spoons for $2.98. Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.

Answers

Answer:

The unit price is the price of a single unit.

To find it, you need to find the quotient between the total price and the number of objects you get for that price.

Brand A:

You get 25 spoons for $1.97

Then the unit price is:

unit price of brand A = $1.97/25 = $0.079

Brand B:

You get 48 spoons for $2.98

Then the unit price is:

unit price of brand B: $2.98/48 = $0.062

Here we can see that the unit price for brand B is smaller, then the better buy is brand B.

The altitude of the right triangle is the geometric mean of the 2 parts of the side it separates.

a. The answer would be sqrt(18*32)=24

The question to the second question can be answered by using the Pythagorean theorem.

32^2+24^2=1600=40^2

b. The answer would be sqrt40^2=40

The beach, the parking lot and the refreshment stand are illustrations of similar triangles.

The distance between the spot and the parking lot is 24 mThe distance between the refreshment stand and the parking lot is 40 m

(a) The distance between the spot and the parking lot

Represent this distance with d.

So, the equivalent ratio is:

[tex]\mathbf{32:d = d : 18}[/tex]

Express as fractions

[tex]\mathbf{\frac {32}d = \frac{d}{ 18}}[/tex]

Cross multiply

[tex]\mathbf{d \times d = 32 \times 18}[/tex]

[tex]\mathbf{d^2 = 576}[/tex]

Take square roots

[tex]\mathbf{d = 24}[/tex]

Hence, the distance between the spot and the parking lot is 24 m

(b) The distance between the refreshment stand and the parking lot

Represent this distance with d.

Using Pythagoras theorem we have:

[tex]\mathbf{d^2 = 32^2 + 24^2}[/tex]

[tex]\mathbf{d^2 = 1600}[/tex]

Take square roots

[tex]\mathbf{d = 40}[/tex]

Hence, the distance between the refreshment stand and the parking lot is 40 m

The variable y varies directly as x and inversely as z. When x = 4 and z= 14, y=2.
Write a combined variation equation and find y when x = 6 and z= 3.

Answers

Given:

The variable y varies directly as x and inversely as z. When x = 4 and z= 14, y=2.

To find:

The combined variation equation and find y when x = 6 and z= 3.

Solution:

The variable y varies directly as x and inversely as z.

[tex]y\propto \dfrac{x}{z}[/tex]

[tex]y=k\dfrac{x}{z}[/tex]           ...(i)

Where, k is the constant of proportionality.

Putting x=4, y=2 and z=14, we get

[tex]2=k\dfrac{4}{14}[/tex]

[tex]2=k\dfrac{2}{7}[/tex]

[tex]2\times \dfrac{7}{2}=k\dfrac{2}{7}\times \dfrac{7}{2}[/tex]

[tex]7=k[/tex]

Putting k=7 in (i), we get

[tex]y=7\dfrac{x}{z}[/tex]

Putting x=6 and z=3, we get

[tex]y=7\times \dfrac{6}{3}[/tex]

[tex]y=7\times 2[/tex]

[tex]y=14[/tex]

Therefore, the required equation is [tex]y=7\dfrac{x}{z}[/tex] and the value of y is 14 when x = 6 and z= 3.

Melissa earns a 2% commission on the first $750 of sales she makes each week. She earns a 3% commission on the amount of her sales that are greater than $750 each week. Melissa earned $37.50 in commissions last week.


Which equations correctly calculate how much money in dollars, x, Melissa made in sales last week?


Select all that apply.


0.02(750)+0.03(750−x)=37.5


0.03(x−750)=37.5−15


15+0.03x−22.5=37.5


0.02(750)+0.03(x−750)=37.5


15−0.03x+22.5=37.5


0.03(750−x)=37.5−15

Answers

The  equations that are correct are:

0.02(750) + 0.03(x - 750) = 37.5

0.03(750 - x) = 37.5 - 15

Given:

Melissa earns a 2% commission on the first $750 of sales.

She earns a 3% commission on greater than $750 each week.

1. Sales up to $750:

Melissa earns a 2% commission on the first $750 of sales.

=0.02(750)

= 15

2. Sales exceeding $750:

Melissa earns a 3% commission on the amount of sales that exceed $750.

0.03(x - 750) = 37.5 - 15

Combining both equations, we have:

0.02(750) + 0.03(x - 750) = 15 + 37.5 - 15

15 + 0.03x - 22.5 = 37.5

0.03x - 7.5 = 37.5

Adding 7.5 to both sides

0.03x = 45

Dividing both sides by 0.03

x = 1500

Therefore, the correct equations that calculate the amount of money Melissa made in sales last week are:

Equation 1: 0.02(750) + 0.03(x - 750) = 37.5

Equation 2: 0.03(750 - x) = 37.5 - 15
