Answer:

x=7/2

Step-by-step explanation:

first, multiply 3/4 and 5/8 into the () to get rid of them.

3/4x -3/4 = 5/4x -5/2

next, combine like terms

5/4x -3/4x = -3/4 +5/2

1/2x = -3/4 +10/4 = 7/4

divide both sides by 1/2

x= 7/2

How many times larger
is 8 x 10^4 than 8 x 10^1

Answers

Answer:

8x10^4=80,000

8x10^1=80

79,920 times larger!

Step-by-step explanation:

Hope that helps! :)

The values 8 * 10^4 is 1000 times larger than 8 * 10^1

Scientific notations are expressions written in the form A * 10^n

Given the following scientifc notations:

A = 8 x 10^4

B = 8 x 10^1

In order to know how many times larger  is 8 x 10^4 than 8 x 10^1, we will take the ratio of both values as shown;

Ratio =

[tex]\frac{A}{B} = \frac{8 \times 10^4}{8 \times 10^1}\\ \frac{A}{B} = 1 \times 10^{4-1} \\ \frac{A}{B} = 10^3\\ \frac{A}{B} = 1000[/tex]

This shows that the values 8 * 10^4 are 1000 times larger than 8 * 10^1

Company cuz closed at $52.93 per share with a P/E ratio of 15.17 how much were earnings per share

Answers

Answer: $3.49

Step-by-step explanation:

Earnings per share shows how much of the profit of the company every share will get.

You can use it to calcutae the P/E ratio through the following formula:

P/E ratio = Share price / Earnings per share

15.17 = 52.93 / EPS

EPS * 15.17 = 52.93

EPS = 52.93 / 15.17

= $3.49

Larry wants to purchase birthday gifts for his twin sisters. One sister likes daises which costs $2.00 per stem and the other likes tulips which costs $3.00 per stem.

Let x = number of daisies

Let y = number of tulips

Since one sister likes daises which costs $2.00 per stem and the other likes tulips which costs $3.00 per stem, the inequality that could be use to determine how many of each flower he could buy if he only has $35.00 to spend will be:

What’s the answer?!?!?

Answers

Answer:

24 inches

Step-by-step explanation:

You can see in the picture a triangle is formed where the sides are AB, BC, and AC.

The side lengths you have are AC = 16 and BC = 20.

You can use the Pythagorean Theorem, [tex]a^2+b^2=c^2[/tex], so:

[tex]16^2+b^2=20^2[/tex]

[tex]256+b^2=400\\b^2=144\\b=12[/tex]

This means that the length of AB = 12.

It's asking the diameter, and AB is the radius, so you have to do 12 * 2 to find the diameter = 24 inches

In ∆DEF, ∠F = ∠D and EF = 4 cm and DF = 5 cm. Then find the length of DE

Answers

Answer:

DE = 4cm.

Step-by-step explanation:

The Isoscles Triangle Theorem says that:

"If two sides of a triangle are congruent, then angles opposite those sides are congruent."

The converse of this theorem is

"If angles opposite those sides are congruent, then two sides of a triangle are congruent."

Therefore, since ∠F is congruent to ∠D and are opposite sides ED and EF

while EF = 4 cm and DF = 5 cm.

DE = 4cm.

find the area of shaded region in given figure 14 cm and 7 cm

Answers

Given:

The radii of circles are 14 cm and 7 cm.

To find:

The area of the shaded region.

Solution:

Area of a circle is

[tex]Area=\pi r^2[/tex]

From the given figure, it is clear that

Area of shaded region = Area of larger circle - Area of smaller circle

                                      = [tex]\pi (14)^2-\pi (7)^2[/tex]

                                      = [tex]\dfrac{22}{7}\times 14\times 14-\dfrac{22}{7}\times 7\times 7[/tex]

                                      = [tex]616-154[/tex]

                                      = [tex]462[/tex]

Therefore, the area of the shaded region is 462 sq. cm.

Answers

Answer:

25c^2-30cd

Step-by-step explanation:

The product of expression is,

⇒ 5c (5c - 6d)

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ (5c - 3d)² - 9d²

Now, We can write the expression in form of product as;

⇒ (5c - 3d)² - 9d²

⇒ (5c - 3d)² - (3d)²

⇒ (5c - 3d - 3d) (5c - 3d + 3d)

⇒ (5c - 6d) (5c)

⇒ 5c (5c - 6d)

Thus, The product of expression is,

⇒ 5c (5c - 6d)
