Please help me with this math problem!! :)

Answer:

3.8

Step-by-step explanation:

5% times 20 is 100% and that is the number we are trying to find so of we multiply .19 by 20 we should get 3.8 wich is promotional to the 100%

Answer:

Step-by-step explanation:

It is very close to each if the points with no outliers.

Answer:

(a) P = 32.5 feet

(b) P = 108-2x feet

Step-by-step explanation:

Note: Perimeter is the total distance around the border of a shape.

(a)

P = 14' + 27'' + 14' +27'' ; First we have to covert the 27'' (27 inches to feet)

[tex]27*\frac{1}{12} = \frac{27}{12} =\frac{9}{4}[/tex] = 2.25feet

P = 14'+2.25'+14'+2.25'

P = 32.5' = 32.5 feet

(b)

P = 15'+29'+(15'-x')+3'+7'+3'+(7'-x')+29' ; where x is the overlapping distance of the 2 rectangles of Foundation B.

P = 108' -2x'

P = 108-2x feet

Note: there is not enough information to determine the vaule of x from the problem.

Answer:

The first choice:

x: -5, -4, -3, -2, -1

y: -5, -3,  -1,   1,  3

Step-by-step explanation:

If we apply the equation here...

y = 2x + 5

(Let's use -1 for example)

y = 2(-1) + 5 --> y = -2+5, which gives us 3

On the table, it says that the y is 3, so it proves that it is correct

If you apply the equation for all of the x's, it'll give you the y's for the first choice. This doesn't apply to the rest of the tables, so the first table is the correct choice

The values are satisfied by

x      y

-5    -5

-4    -3

-3    -1

-2     1

-1      3

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given:

Y= 2X +5

let us put the value for X

X= 0

Y = 5

and, X=1

Y = 2 + 5 = 7

and, X= 2

Y= 4 + 5 = 9

and, X=3

Y = 6 + 5 = 11

and, X= 5

Y = 10 + 5= 15

and, X= -1

Y= -2 + 5 = 3

Hence, these values are satisfied by

x      y

-5    -5

-4    -3

-3    -1

-2     1

-1      3

ALL of the following expressions are NOT equivalent to 64^5t^2+3t

Step-By-Step Explanation:

Khan Academy

To determine whether each expression is equivalent to [tex]64^5t^2 + 3t[/tex], we will simplify each expression by evaluating the calculations.

Expression 1:   [tex]64^5t^2 + 3t[/tex]

Expression 2:  [tex](4^3)^5t^2 + 3t = 4^(3*5)t^2 + 3t = 4^15t^2 + 3t[/tex]  

Expression  3:  [tex](8^2)^5t^2 + 3t = 8^(2*5)t^2 + 3t = 8^10t^2 + 3t[/tex]  

Expression 4:   [tex](2^6)^5t^2 + 3t = 2^(6*5)t^2 + 3t = 2^30t^2 + 3t[/tex]  

Expression 5:   [tex](8^8)^3t^2 + 3t = 8^(8*3)t^2 + 3t = 8^24t^2 + 3t[/tex]  

Expression 6:   [tex]64^5t^2 + t + 2t = 64^5t^2 + 3t[/tex]

After evaluating each expression, we can see that all the expressions are equivalent to [tex]64^5t^2 + 3t[/tex]. The calculations show that regardless of the specific values used, the expressions simplify to the same result. Therefore, it can be concluded that all six expressions are equivalent to [tex]64^5t^2 + 3t.[/tex]

Answer:

g+r=15  and 2.00g+4.50r=37.50 are the two equations you need to use

Step-by-step explanation: IM NOT COMPLETLEY SURE THO

Answer: C

The total number of pounds of trail mix is 15. The pounds of granola added to the pounds raisins has to equal 15. So, one of the equations is g + r=15.

In total the cost of the granola and the cost of the raisins must be equal to $37.50. Since the granola costs $2 per pound and the raisins cost $4.50 per pound, 2g + 4.5r= 37.5.

Answer:

y = -3x + 11

Step-by-step explanation:

To find the equation of the line we would plug in the given info into the point slope equation:

[tex]y-y_{1} =m(x - x_{1} )[/tex]

In this case (x1, y1) is (4, -1) and m is -3:

y - (-1) = -3(x - 4)

We can simplify as follows:

y + 1 = -3x + 12

y = -3x + 11

Answer:

[tex]7x^3(7x^2-9 )[/tex]

Step-by-step explanation:

To factor, you have to find the GCF of 49 and 63 and the GCF of [tex]x^{5}[/tex] and [tex]x^3[/tex]

Factor 49: 1,7, and 49

Factor 63: 1, 3, 7, 9, 21, 63

Factor [tex]x^{5}[/tex]: [tex]x*x*x*x*x[/tex]

Factor [tex]x^3[/tex]: [tex]x*x*x[/tex]

So the GCF of 49 and 63 is 7

The GCF of [tex]x^{5}[/tex] and [tex]x^{3}[/tex] is [tex]x^3[/tex]

We multiply 7 by [tex]x^{3}[/tex] to get [tex]7x^3[/tex]

So now we start to factor out the GCF of [tex]49x^5-63x^3[/tex]

[tex]7x^3(\frac{49x^5}{7x^3}+ \frac{63x^3}{7x^3} )[/tex]

[tex]\frac{49}{7} =7\\x^5-x^3=x^2[/tex]

[tex]\frac{63}{7} =9\\x^3-x^3=x^0[/tex] because [tex]x^{0}[/tex] can't be written as an exponent we don't write [tex]9x^0[/tex]

When we factor we get [tex]7x^3(7x^2-9 )[/tex]

1,3,5,7 = 126°

2,4,6,8 = 54°

Here your go m'dear

Given, ∠3 = 126°.

∠3 =∠1 = 126° (vertically opp. angles)

∠3 =∠5 = 126° (alternate interior angles)

∠3 =∠7 = 126° (corresponding angles)

Now, ∠2 = 180° - 126° = 54° (linear pair/supplementary angles)

∠2 = ∠4 = 54° (vertically opp. angles)

∠2 = ∠8 = 54° (alternate interior angles)

∠8 = ∠6 = 54° (vertically opp. angles)

See below:

Step-by-step explanation:

(Apologies for the other answer, the moderation team is looking at it.)

So, we can solve this problem by taking 2 steps, Solving and Unit Value.

We'll start off with finding the unit value for 1 cm and how many Newtons we get per one cm.

We can solve for that by dividing both sides by 20 to find the Unit Value.

[tex]\frac{20}{20}=1\\\frac{28}{20}=1.4\\[/tex]

Upon solving, we know that 1.4 is for one unit price. We can then figure out the other blanks by solving it, which we will be doing next.

Solving

To find the first value, we know that the ratio for [tex]I:O[/tex] with I being Input and O being output is 1.4. We know that because in the unit section, we figured the rate out.

We can now use that to find the Newtons, to do that, we must multiply 55 by 1.4.

[tex]55*1.4=77[/tex]

We have found out our first blank which is 77.

We can solve for 140 by dividing it by 1.4 because to get 1 Newton we divide by 1.4 on this table and to get the opposite we have to do the opposite of multiplying; dividing.

We divide 140 by 1.4 and we get 10.

[tex]\frac{140}{1.4}[/tex] = 100

To solve for one, we did that in the beginning, and that would be 1.4
