The length of 2 sides on an isosceles triangle is 15. What is the range of possible lengths for the other leg? Explain.

Answers

Answer 1

The other leg must be > 0.
Also the third side must be less than the sum of the 2 equal sides.

So the range for the third side x is 0 < x < 30

Unless you meant that sum of the 2 equal sides is 15 in which case the answer is

0 < x < 15.

Erica solved the equation −5x − 25 = 78; her work is shown below. Identify the error and where it was made. −5x − 25 = 78 Step 1: −5x − 25 − 25 = 78 − 25 Step 2: −5x = 53 Step 3: negative five times x over negative five = fifty-three over negative five Step 4: x = negative fifty-three over five Step 1: She should have added 25 to each side. Step 1: She should have divided both sides by −5. Step 3: She should have divided both sides by −5. Step 3: She should have multiplied both sides by −5.

Answers

Hi there! Her mistake is in step 1.

She subtracted -25 by 25. -25 - 25 = -50

What she SHOULD have done was add 25 to each side. This obeys the property of reciprocals.

-25 + 25 = 0

Hope this helps.

:)

Have you tried solving x yourself to possibly identify the error?

We know that if we have something like
2x - 3 = 2 and to solve for x, we have to get x alone as much as we can. We have to take the opposite of -3 (which is +3) and add it to both sides of the equations
2x - 3 + 3 = 2 +3 , what that does is cancel out the three on both sides.

For this situation Erica has -5x -25 = 78 the first step she took to try and get x alone as much as she could was to subtract 25 on both sides, which is wrong!!
-5x - 25 - 25 = 78 -25 does not cancel 25 on the left hand side. In fact it doubles it.

So Erica messed up on step 1. She should have added 25 on both sides.

What two integers is the square root of 87 between

Answers

nine and ten is the answer

The two integers that surround the square root of 87 are 9 and 10.

The first step is to find out the square root of 87:

= √87

= 9.33

Integers are all whole numbers numbering from 1 to infinity so the two integers the square root will be between are the integers immediately below 9.33 and above it. These numbers are:

9 and 10

9 is immediately below 9.33

10 is immediately above 9.33

In conclusion, the square root of 87 is between 9 and 10.

r = 2/3t + v , for t
need answer a how u got it

Answers

R= 2/3t + v
R-v=2/3t
3(R-v)=2t
t= 3(R-v)/2

Final answer:

To solve the equation r = 2/3t + v for t, subtract v from both sides and then multiply by the reciprocal of 2/3. The final equation is t = (3/2)(r - v).

Explanation:

You are looking to solve the equation r = 2/3t + v for t. To do this, you need to isolate t on one side of the equation. Here are the steps:

Subtract v from each side. This gives us: r - v = 2/3t. To get t alone, we need to get rid of 2/3. Therefore multiply both sides of the equation by the reciprocal of 2/3, which is 3/2, resulting in: (3/2)(r-v) = t.

So the answer is t = (3/2)(r-v).

Find 2 pairs of numbers whose LCM is the product Of The Numbers

Answers

5 and 4
3 and 2

Since these two pairs of numbers have no common factors, the LCM will be the product of them.

Hope this helps!

Final answer:

Pairs of numbers whose LCM is the same as their product occur with prime numbers or the number one with any other number. For instance, 2 and 3, and 1 and 6 are such pairs of numbers, since their LCM and their product is 6 in both cases.

Explanation:

To find two pairs of numbers whose LCM (Least Common Multiple) is the product of the numbers themselves, you need to understand that this will only happen with pairs of prime numbers or the number one with any number. Prime numbers are those numbers that have only two distinct positive divisors: 1 and the number itself. If you multiply two prime numbers, or a number and the number one, the product will be their LCM. For example, if you take the numbers 2 and 3, which are both prime, their product is 6 and so is their LCM. The same thing happens if you take the numbers 1 and 6, whose product is 6, and 6 is also their LCM. So, 2 and 3, and 1 and 6 are two pairs of numbers whose LCM is the product of the numbers.

Greatest common factor or 60 and 20

Answers

To find the greatest common factors of these 2 numbers, first write them as product of prime numbers.

(a prime number is a number whose only factors are 1 and themselves, for example: 2, 3, 11 ...etc)

To write the numbers as product of prime factors, just divide them continuously until all factors are primes:

[tex]60=6\cdot10=(2\cdot3)\cdot(2\cdot5)=2\cdot2\cdot3\cdot5\\\\20=2\cdot10=2\cdot(2\cdot5)=2\cdot2\cdot5[/tex]

The greatest common factor, must contain the largest number of common factors found in both numbers which are 2- 2's and one 5

So the greatest common factor is [tex]2\cdot2\cdot5=4\cdot5=20[/tex]

Answer: 20

The greatest common factor of the numbers 60 and 20 is 10.

We have,

To find the greatest common factor (GCF) of 60 and 20, we can list the factors of both numbers and identify the largest factor they have in common.

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.

The factors of 20 are: 1, 2, 4, 5, 10, 20.

From the list above, we can see that the common factors of 60 and 20 are 1, 2, 4, 5, and 10.

Among these common factors, the largest one is 10.

A semiconductor manufacturing company employs 1,000 people. The average weekly salary of each employee is $750. Select the graph that correctly shows the total cost to the company of paying its employees during a year.

Answers

I'd say the top one. The second and third both exceed a year. The last seems to be similar to the top, but I was taught that the dependent variable is the y axis.

Answer:

Option A

Step-by-step explanation:

The semiconductor manufacturing company employs 1000 people average weekly salary of each employee is $750.

So total cost to the company = 750 × 1000

= $750,000 per week.

From the given graphs, the ratio of amount to weeks will show the cost to the company for a week.

Graph A. Cost to the company = [tex]\frac{300\times 1,000,000}{40}[/tex] =

$750,000 per week.

This graph is for 52 week so the correct one.

Graph B. Graph B is same as graph A but data is given for more than 60

weeks so incorrect graph.

Graph C. Ratio of amount and weeks is [tex]\frac{40000000}{30}[/tex]

= $1333333.33 per week So incorrect option.

Graph D. Graph D is same as graph A and B but it is for less than 40 weeks.

So Incorrect graph.

Option A is the answer.
