A flagpole and a model flag pole have a scale factor of 1 in.= 4 ft. If the model pole measures 12 inches, how tall is the actual pole?
Answer:
[tex]48\ \text{feet}[/tex]
Step-by-step explanation:
[tex]1\ \text{inch}[/tex] of the model is [tex]4\ \text{feet}[/tex] of the actual pole.
Here, the pole which is present in the model measures [tex]12\ \text{inches}[/tex], so
[tex]12\ \text{inches}[/tex] of the model will be [tex](12\times 4)\ \text{feet}=48\ \text{feet}[/tex]
Hence, the actual pole will be [tex]\boldsymbol{48\ \text{feet}}[/tex] tall.

You are at Coney Island Amusement Park, and burgers
cost $5 and hot dogs cost $3. You and your friends
spend $45. This is modelled by the equation
5b + 3h= 45.
Is the solution (2, 5) a viable solution?
show your work to the left]
Answer: No, the ordered pair (2,5) is not a viable solution
===========================================================
Explanation:
(2,5) means that b = 2 and h = 5
I'm assuming each ordered pair is of the form (b,h) where b comes first, since b is before h in the alphabet.
So if b = 2 and h = 5, then we can replace each letter with those numbers to get the following:
5b + 3h = 45
5*2 + 3h = 45 ..... b replaced with 2
5*2 + 3*5 = 45 ..... h replaced with 5
10 + 15 = 45
25 = 45
We don't get the same number on both sides, so (b,h) = (2,5) is not a solution.
--------------
Put another way:
If b = 2 and h = 5, this means you bought 2 burgers and 5 hot dogs
1 burger = $5
2 burgers = 2*5 = $10
1 hot dog = $3
5 hot dogs = 5*3 = $15
total amount spent = $10 + $15 = $25
total amount spent = $25
This does not match up with the $45 total spent that we're given. So this is another way to see we don't have a solution.

FREE BRAINLIEST! if you can answer this correctly ill give you brainliest and answer some of the questions you have posted :) thank you very much!!! (22pts)
Answer:
no solution
Step-by-step explanation:
x²-4 is (x+2)(x-2), which is your least common multiplier
So first, eliminate the denominators by multiplying all terms by (x+2)(x-2)
(x+2)(x-2)/(x-2) + (6x)(x+2)(x-2)/(x+2)(x-2) = 3(x+2)(x-2)/(x+2)
Then simplify
(x+2) + (6x) = 3(x-2)
combine the variables, and expand the right side of the equation
7x + 2 = 3x - 6
Subtract 2 from both sides
7x = 3x - 8
Substract 3x from both sides
4x = -8
Divide both sides by 4
x = -2
Although x = -2, the final answer is undefined.
Because if you plug x = -2 back into the equation, you would get...
for example, 3/(x+2) will become 3/(-2+2), which is 1/0
it is not possible to divide by 0
anything divided by 0 is undefined, therefore this equation has no solution.
PLEASE HELP! ITS A DECENTLY EASY QUESTION BUT I CANT FIGURE IT OUT!
Answer:
3,4 and 5 are correct........☺
Answer:
3,4,5
Step-by-step explanation:
To answer, we must go through all the expressions shown, solve them, and make sure that they are exactly like 3xy + 6yz.
1. We must distribute 3 to whatever is in the parentheses, but if you look, you can see that we have to multiply 3 by 6yz, which would come out to 18yz, and that is not in the original expression, so this one is FALSE
2. For this expression, we can rule it out because the first part of the expression would be 3xyz, and that is not a part of the original expression, this is one is FALSE
3. This expression, if you distribute the 3y, you get 3yx + 6zy, which is the same as the original expression, even if the variables are a bit jumbled, they all have the same value, so this one is TRUE
4. If you distribute y for this expression, you get y3x + y6z, which is the same as the original expression, because as I said before, the variables can be jumbled, but as long as all the values are there, we can safely say that this expression is TRUE
5. As you can see, this expression is the same as 4, so this one is also TRUE
Hope this helps :)

Hannah and her friend are training to run in a 2-mile race. On Monday, Hannah ran ½ mile. On Tuesday, she ran ⅕ mile farther than she ran on Monday.
a. How far did Hannah run on Tuesday?
b. If her friend ran ¾ mile on Tuesday, how many miles did the girls run in all on Tuesday?
Answer:
A: Hannah ran 0.7 miles on Tuesday
B: They ran 1.45 miles in total
Step-by-step explanation:
If you put all the fractions into decimal form it would be;
1/2 = 0.5
1/5 = 0.2
3.4 = 0.75
So, you add all of the decimals together;
0.5 + 0.2 = 0.7
0.7 + 0.75 = 1.45
What are the factors of -36 that will sum to give you a -5?
Answer:
4, and -9
Step-by-step explanation:
Well, to solve this problem, lets first list all the factors of -36.
-36 = 1*(-36)
-36 = 2 * (-18)
-36 = 3 * (-12)
-36 = 4 * (-9)
-36 = 6 * (-6)
-36 = 12 * (-3)
-36 = 18 * (-2)
-36 = (-36) * 1.
So, we can see that 4 + (-9) = -5.

2.5+3(5-2.1p)=-13.37
Answer:
p=4.9
Step-by-step explanation:
Answer:
4.9
Step-by-step explanation:
[tex]2.5 + 3(5 - 2.1p) = - 13.37[/tex]
1) Open the brackets by multiplying 3 with each term present inside the bracket.
[tex] = > 2.5 + 15 - 6.3p = - 13.37[/tex]
2) Add the constant teems present in left-hand side.
[tex] = > 17.5 - 6.3p = - 13.37[/tex]
3) Take 17.5 to right-hand side by changing its sign from positive to negative.
[tex] = > - 6.3p = - 13.37 - 17.5[/tex]
[tex] = > - 6.3p = - 30.87[/tex]
4) Take -6.3 to right-hand side by dividing -30.87 by --6.3.
[tex] = > p = \frac{ - 30.87}{ - 6.3} = 4.9[/tex]

Answer:
x = -5
y = 20
Step-by-step explanation:
3x + y = 5
3x - 3x + y = 5 - 3x
y = 5 - 3x
--------------------------------------------------------
4x + 2y = 20
4x + 2(5 - 3x) = 20
4x + 2(5) + 2(-3x) = 20
4x + 10 - 6x = 20
10 - 2x = 20
10 - 10 - 2x = 20 - 10
-2x = 10
-2x ÷ -2 = 10 ÷ -2
x = -5
--------------------------------------------------------
y = 5 - 3x
y = 5 - 3(-5)
y = 5 + 15
y = 20

(05.02) In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.
A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40 degree angle and angle x extends below the straight line. The angle formed is labeled angle y.
Write and solve an equation to determine the measure of angle y.
☁️My Answer☁️:
y = 90°
✧My Step-by-step explanation✧:
The angle x forms a straight line with the both the 50° angle and the 40° angle:
x + 50° + 40° = 180°
x = 90°
Which means…
y = x = 90°
¿Qué peso transporta una tractomula que lleva 134 bultos de trigo de 62 kilos cada uno, 28 sacos de café de 50 kilos cada uno y 37 bultos de arroz de 75 kilos cada uno?
Answer:
the total weight is 12,483 kilos
Step-by-step explanation:
The computation of the weight is shown below:
Wheat = 134 × 62 = 8308
Coffee = 28 × 50 = 1400
Rice 37 × 75 = 2775
Total weight is
= 8308 + 1400 + 2775
= 12,483 kilos
Hence, the total weight is 12,483 kilos

The length of a rectangle is 3cm more than its width.If the area of the rectangle is 28cm^2,find the width.
Answer: The dimensions of the rectangle are 7 cm × 4 cm
Step-by-step explanation:
let,
Breadth of the rectangle (l) = x
Length of the rectangle (b) = x + 3
Area of the rectangle = 28 cm²
Area of the rectangle = l × b
⇒ (x) × (x + 3) = 28
⇒ x² + 3 x = 28
⇒ x² - 3 x - 28 = 0
⇒ x² - 7 x + 4 x - 28 = 0
⇒ (x - 7) + 4(x - 7) = 0
⇒ (x - 7)(x + 4) = 0
⇒ x = 4
Breadth = 4 cm
Length -
⇒ 4 + 3
⇒ 7 cm
