Answer:
12 inchesStep-by-step explanation:
Given the conversion factor;
2inches = 30feet
if the height of the building is 180feet, we are to find the height of the scale model in inches.
Let x = 180 feet.
Equating both;
2inches = 30feet
x inches = 180feet
Cross multiply;
30 * x = 2 * 180
30x = 360
x = 360/30
x = 12inches
Hence the height of the scale model in inches is 12inches
Answer: 60 in
Step-by-step explanation:Let x = 180 feet.
Equating both;
2 inches = 30 feet
x inches = 180 feet
Cross multiply;
30 * x = 2 * 180
30 x = 360
x = 360/30
x = 60 inches

Lola's puppy weighed 19 ounces on the second visit the puppy had gained 9 ounces on the third visit the puppy heaven gained another 7 ounces what is the percent increase since the first visit and the puppy weighed around to the nearest percent
Answer:
84%
Step-by-step explanation:
In order to calculate this, we first need to calculate the total weight of the puppy on the last visit. We do this by adding the weight that the puppy gained each visit like so...
19oz + 9oz + 7oz = 35oz
Now that we have the final weight we simply divide the final weight by the initial weight of the puppy in the first visit. Then we subtract 1 from that value and multiply by 100 to get the percentage increase.
35oz / 19oz = 1.84
1.84 - 1 = 0.84
0.84 * 100 = 84%
Finally, we can see that the puppy had an 84% increase since the first visit.

A toy factory makes 15 teddy bears every 10 minutes. The factory makes teddy bears for 8 hours each work day. What is the fewest number of work days the factory will need to make 5,000 teddy bears? Write an explanation to show how you determined your answer.
Answer:
1 day
Step-by-step explanation:
Cuz if 15 bears are made in 10 min you multiply by 60 cuz 60 min = 1 hour, so 15 times 60=900 then if the work 8 hr a day then u multiply 900 by 8 to get 7200 bears
What is the slope of the line that passes through the points (4, 6)and (-16, -18)? Write your answer in the simplest form.
Answer:
6 / 5
I hope it is correct.
Step-by-step explanation:
Slope is (y2 - y1) / (x2 - x1)
choose two points: (4, 6) and (-16, -18)
(-18 - 6) / (-16 - 4)
-24 / -20 (simplify by -4)

HELP ASAP PLS Which table represents the same equation as
y= -1/2x+5
What number should be added to both sides of the equation to complete the sqaure x^2+8x=4
The number 16 must be added to the equation for making it a perfect square.
We must have the idea of algebraic identities to solve this problem. The identity of the sum of square of two variables is given below.
We know that [tex](a+b)^{2}= a^{2} +2ab+b^{2}[/tex].
So make a perfect square the equation must be of the form of [tex]a^{2} +2ab+b^{2}[/tex]
Given, [tex]x^{2} +8x=4[/tex]
⇒ [tex]x^{2} +2*4*x+ 4^{2}=4+4^{2}[/tex]
⇒ [tex](x+4)^{2}=20[/tex]
So, to complete the square we have added 16 to both the sides of the equation and now it is in the form of [tex](a+b)^{2}[/tex].
The required number to be added is 16.

Step-by-step explanation:
Classify √3.
√3 means "the nonnegative square root of 3."
The square root of a number is a number that when multiplied by itself equals the original number. The radical symbol √ is used to denote the nonnegative square root.
√ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.
We are given a number √ 3.
We need to classify the number.
First we can see that, this is the non negative square root of the number 3.
That is when we multiply √ 3 two times, we get the number 3.
Also, we can see that, it will be an irrational number as it will be non terminating and non repeating number.
That is it will be a real irrational number.
Therefore, we get that, √ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.

The points (-5, 5) and (5, r) lle on a line with slope -3. Find the missing coordinate r.
Answer:
r = -25
Step-by-step explanation:
slope is change in "y" over change in "x"
so whatever your change in "x" is between the two points, the change in "y" needs to be in proportion to the slope of -3.
Here the change in "x" is +10, and to make the proportion of the slope equal to -3, the change in "y" needs to be -30.
Starting from the "y" coordinate of 5, a change in "y" of -30 will give you r = -25
So the two points are (-5, 5) and (5, -25)
