if u want u can answer question 14 and 15 but if u don’t just answer 14

Answers

Answer 1

Answer:

For #14, (around) 108 times.

#15 = 53

Step-by-step explanation:

14)

2.69*10^5 = 269000

2.5*10^3 = 2500

269000/2500 = 107.6

Rounding up, we get 108

15)

√(53 - 8)2 + (31 - 3)2

= √(45)2 + (28)2

= √2809

= 53

The altitude of an equilateral triangle is 7 units long. The length of one side of the triangle is ____ units. 7 14

Answers

The length side of equilateral triangle is 8.08 units

What is Altitude?

The altitude or height of an equilateral triangle is the line segment from a vertex that is perpendicular to the opposite side.

Here, let the side of the equilateral triangle be x units

given altitude of the equilateral triangle = 7 units

we know,

Altitude = √3/2 X side

7 = √3/2 X x

x = 7 X 2 / √3

x = 14/√3

x = 8.08 units

Thus, the length side of equilateral triangle is 8.08 units.

How do you add negative numbers with positives

Answers

when we add negative number to the positive number we just subtract the smaller number from the larger number and put the sign or the larger number after words

examples:- First

[tex]5 + ( - 2) = 5 - 2 = 3[/tex]

like here we put + in front of 3 as larger number 5 is positive

second

[tex] - 7 + 5 = - 2[/tex]

we put negative because 7 is larger then 5 and 7 is negative

please help i dont understand how to find c i know about theorems but

Answers

Ok so firstly, you need to remember that when a radius is touching a tangent, the angle is always equal to 90°. So x + 57° = 90°. That means your angle is 33°. You have drawn a right angle which is correct so the left triangle's angle is 90° - 33° = 57°. Now because both sides of the triangle is radius, that means c and 57° are equal. That means c = 57°.

Answer:

c = 57 degrees.

Step-by-step explanation:

This is the Alternate Segment theorem:

The angle between a chord of a circle and a tangent to the circle = the angle subtended by the chord in the alternate segment.

So c = 57 degrees.

Answers

Answer:

Step-by-step explanation:

1 out of 12 can be written as a fraction 1/12

Now we convert the fraction to a decimal with division. Using long division the 12 goes outside the division symbol and 1 on the side. 12 doesn't go into 1 so we add a decimal to the answer and a 0 after the 1. 12 doesn't go into 10 so we add another 0. 12 goes into 100 8 times. 8 goes on top after 0.08 and then we finish the long division. We would have 4 remaining. Add another 0. 12 goes into 40 3 times. This is then where the division becomes repetitive. With more threes. Depending on where youryou're supposed to Round to the answer is 0.0833

How do I solve for 4h=57.6

Pls explain bc I don’t understand Does h = 14.4

Answers

Answer:

h = 14.4

Step-by-step explanation:

4h=57.6

Divide each side by 4

4h/4 = 57.6/4

h = 14.4

Answer:

See explanation

Step-by-step explanation:

Always divide the constant by itself and the value it equals.

1) Divide both sides by 4.

[tex]h=\frac{57.6}{4}[/tex]

2) Simplify [tex]\frac{57.6}{4}[/tex] to [tex]14.4[/tex].

h = 14.4

To check our answer,

4h = 57.6

1) Let h = 14.4

4 * 14.4 = 57.6

2) Simplify 4 × 14.4 to 57.6.

57.6 = 57.6

each of one senior citizen ticket and one student ticket?

Answers

Answer:

Price of senior citizen ticket = $7

Price of student ticket = $5

Step-by-step explanation:

Let:

senior citizen ticket price = astudent ticket price = b

Equations formed :

9a + 10b = 1132a + 10b = 64

Subtract : Equation 1 - Equation 2

9a + 10b - 2a - 10b = 113 - 647a = 49a = 7

Finding b

2(7) + 10b = 6410b = 50b = 5

How do I write 780,000 in scientific notation.

I’m having finals and I need lots of help pls explain how u got it answer

Answers

the scientific notation is just another mumble jumble way to write the same thing without so many repetitive zeros, so hmmm 780000 has 4 zeros, so what we do is we can say

78 and 4 zeros following it

or we can say

78 * 10⁴, if we get that product, is 780000

in scientific notation, we only leave one digit to the left of the decimal point

so the same thing above can be written as

78 * 10000, can be written as 78.0 * 10000

or as

7.8 * 100000

or as

0.78 * 1000000

check their product

7.8 * 100000, is really just 780000

because we moved the decimal to the left one more slot, it

became 7.8 * 100000

or in

scientific notation, 7.8 ⨉ 10⁵

Answer:

780,000 [tex]=7.8 * 10^5[/tex]

Step-by-step explanation:

Don't worry! I hope you do great on your finals, goodluck<3.

What is scientific notation?It's a way of expressing numbers that are either too large or too small.The formula for scientific notation is written as shown below:

[tex]a * 10^{b}[/tex]

Variable A represents a number thats absolute value has to be greater than or equal to 1 and less than 10. This is represented below

1 ≤ | a | < 10

Therefore we know that 780,000 will be 7.8, because it is greater than 1 and less than 10 as well can still represent our original number.

[tex]7.8 * 10^b[/tex]

Assuming you know how powers work, if not I'll go over them very quickly.

What is an exponent?An exponent(also called a power or indices) is a tells you how many time you are going to use the number in multiplying a number by itself.

For example 8² = 8 * 8, 8³ = 8 * 8 * 8.

To find what the exponent will be is pretty simple, you take 780,000 and identify what place our number is in.

what I mean by this is if its in, tenths, hundreths, thousands, 10 thousands..

It's pretty obvious that our number is in the 100 thousands place.

Now if you know you're powers pretty well, this will be easy, although let me try to walk you through it if not.

remember the equation:

[tex]7.8 * 10^b[/tex]

We are trying to find b.

10 to what power is equal to 100,000

[tex]10^{1} = 10, 10^{2} = 100, 10^3 = 100, 10^{3} = 1,000, 10^4 = 10,000, 10^5 = 100,000[/tex]

How I like to remember what a power equals is counting the 0's :)

How we know if our answer is correct is plugging it into our equation and solve:

[tex]7.8 * 10^5[/tex]

We know that 10 to the power of 5 equals 100,000.

[tex]7.8 * 100,000[/tex]

and using a calculator, or mental math, or doing it the old fashion way, we know that 7.8 * 100,000 is equal to 780,000

Suppose you buy 3 pizzas for a party. Each pizza is cut into 8slices. Twenty slices are eaten. How many pizzas
were eaten?

Answers

Answer:

2 and a half pizzas were eaten

Step-by-step explanation:

3 pizzas divided into 8 slices is equal to 24 slices. So if 20 slices were eaten, we can do simple math to solve this

There are two ways to do this:

A. divide 20 by 8 to get 2.5

B. subtract a pizza (8 slices) from 20 to get 12. Subtract another pizza (8 more slices) to get 4. The 4 slices left are equal to another half pizza. So in total, there were 2.5 pizzas eaten

What is the expansion of the series sum from n equals 1 to 4 of 2 to the n plus 1 power question mark

2 + 4 + 6 + 8
2 + 4 + 8 + 16
4 + 6 + 8 + 10
4 + 8 + 16 + 32

Answers

The expansion of the series is 2 + 6 + 8 + 10

How to determine the expansion?

The summation expression is given as:

[tex]\sum\limits^4_{n=1} 2(n + 1)[/tex]

When n = 1, we have:

2(n + 1) = 2(1 + 1) = 4

When n = 2, we have:

2(n + 1) = 2(2 + 1) = 6

When n = 3, we have:

2(n + 1) = 2(3 + 1) = 8

When n = 4, we have:

2(n + 1) = 2(4 + 1) = 10

So, we have:

[tex]\sum\limits^4_{n=1} 2(n + 1) = 2 + 6 + 8 + 10[/tex]

Hence, the expansion of the series is 2 + 6 + 8 + 10
