Step-by-step explanation:

here it is the sum of interior angles of a triangle =180

Answer:

35+3 x+2 +52=180

35 +3x+6+52=180

93+3x=180

3x=87

x=87

   ---

    3

x= 29

c=3[x+2]

substituding

c=3[29+2]

c=3x31]

c=93

Answer:

89 she drive to work befor she has to fill

Answer:

4 round tripes

Step-by-step explanation:

First, subtract the miles she has already driven

125 - 5 = 120

Then divide the difference of the miles she has already driven

120 ÷ 30 = 4

Answer:

a1 = 8

a2 = 6

a3 = 4

a4 = 2

a5 = 0

So it would be: 8, 6, 4, 2, 0,...

Step-by-step explanation:

Just plug the term number into the equation.

an = -2n + 10

First term:

a1 = -2(1) + 10 = 8

Second term:

a2 = -2(2) + 10 = 6

Third term:

a3 = -2(3) + 10 = 4

and so on...

Answer:

The denominators of the fractions are 2 and 10.

The fractions with numerators of 1 that have sum of 3 / 5  is calculated below

The sum of the fractions are 3 / 5. Each of the fractions have a numerator of 1. Therefore, let the denominators be x and y

1 / x + 1 / y = 3 / 5

Therefore,

1 / x  + 1 / y = 3 / 5

y + x / xy = 3 / 5

cross multiply

5y + 5x = 3xy

Using hit and trial method,

5(2) + 5(10) = 3(10)(2)

10 + 50 = 60

60 = 60

The values are same.

Therefore, the denominators are 2 and 10.

Answer:

The answer is 47.5 and 72.5

Step-by-step explanation:

So,

Let the number be x and the other number be (x + 25).

Now,

x + (x + 25) = 120

x + x + 25 = 120

2x + 25 = 120

2x + 25 – 25 = 120 – 25

2x = 95

2x/2 = 95/2

x = 47.5

Thus, The number be x is equal to 47.5 and other which is more 25 than other number is (47.5 + 25) = 72.5

-TheUnknownScientist 72

Answer:

The numbers are 47.5 and 72.5

Step-by-step explanation:

Let "x" represent the larger number, then the smaller number would be equivalent to:

[tex]x-25[/tex]

Larger Number + Smaller Number = 120

Therefore...

[tex]x+x-25=120[/tex]

Combine like terms:

[tex]2x-25=120[/tex]

Add 25 to both sides (note we are utilizing the Addition Property of Equality which essentially states that if you add a value to one side of the equation, you must add it to the other side as well):

[tex]2x=120+25\\2x=145[/tex]

Divide both sides by 2 (note we are now utilizing the Division Property of Equality which essentially states that if you divide a value from one side of the equation, you must divide it from the other side as well; the same as the Addition Property of Equality, but with division instead):

[tex]x=\frac{145}{2}\\x=72.5[/tex]

Therefore...

[tex]x-25=72.5-25=47.5[/tex]

Answer:

175

Step-by-step explanation:

Divide. 136.50 divided by 78 then times it by 100 and you get it 175

The percent increase is 56.41%.

We first calculate the difference between the original value and the new value when comparing a rise in a quantity over time. The relative increase in comparison to the initial value is then determined using this difference, and it is expressed as a percentage. The percentage increase formula is provided by:

percentage increase = (increase in amount /original amount ) x 100

Given:

Bill in may month- 78

Bill in June month = 122

So, change in amount= 122 - 78 = 44

So, percent increase = 44/ 78 x 100

percent increase = 0.5641 x 100

percent increase = 56.41%

Hence, the percent increase is 56.41%.

Answer:

x = 11.25 and y = 18.75

Step-by-step explanation:

ΔABD ≅ ΔBCD

⇒ 20 : 15 = 15 : x

⇒ 20/15 = 15/x

⇒ x = 15 × 15/20

⇒ x = 11.25

⇒ 25 : 20 = y : 15

⇒ 25/20 = y/15

⇒ y = 25/20 × 15

⇒ y = 18.75

Answer:

8%

Step-by-step explanation:

The original perimeter is 100cm

The 20cm is representative of the width

30cm is representative of the length

length is increased by 10%

30+(.10 x 30)

(1 + .10) × 30

(100% + 10%) × 30

110% × 30

110 ÷ 100 × 30

110 × 30 ÷ 100

3,300 ÷ 100

= 33

length is increased by 5%

20 + (5% × 20) =

20 + 5% × 20 =

(1 + 5%) × 20 =

(100% + 5%) × 20 =

105% × 20 =

105 ÷ 100 × 20 =

105 × 20 ÷ 100 =

2,100 ÷ 100 =

= 21

New perimeter: 108 cm

Percentage increase:

(108-100):100*100 =

(108:100-1)*100 =

108-100 = 8

= 8%

Answer:

Since we assume the variances of the two populations are the same, we can use the pooled variance in the computation of the t-statistic:pooled variance (Sp^2) = (n1-1)s1^2 + (n2-1)*s2^2 / (n1 + n2 - 2) = (13-1)*19.4^2 + (19-1)*12.6^2 / (13 +19- 2) = 245.8Sp = 15.67t-calc = (mean1 - mean2)/ (Sp * sqrt(1/n1 + 1/n2)) = (83.6-72.9)/(15.67 * sqrt(1/13 + 1/19) = 1.897since this is a right tailed test, the p-value = P(t > 1.897) at n1 + n2 - 2 = 30 degrees of freedom = 0.0337so would not reject.

Step-by-step explanation:

I did this quiz before

Using exponential function concepts, it is found that the student error is in the subtraction of the day rate, as he forgot to subtract from 100% = 1.

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem, the initial value of the computer is of A(0) = 1500, while it decays at a rate of 15% a year, hence r = 0.15 and the equation is:

[tex]A(t) = A(0)(1 - r)^t[/tex]

[tex]A(t) = 1500(0.85)^t[/tex]

Or equivalently, as a sequence:

[tex]a_n = 1500(0.85)^{n-1}[/tex]

Hence, it is found that the student error is in the subtraction of the day rate, as he forgot to subtract from 100% = 1.

Step-by-step explanation:

ey/n + k = t

To get y on its own, the first thing we need to do is subtract k from both sides to get ey/n = t - k. Next, we can multiply both sides by n to get ey = n(t - k). Finally, we can divide by e to get y = n(t - k)/e

Answer:

Option D

Step-by-step explanation:

Given the following question:

Product costs: $90
Monthly bills: $2,300
Manufacturing costs: $75

How much profit did they make in one month if they sold 495 units?

In order to find the answer, we first need to multiply the cost of the product by the units sold last month, then subtract the bills/manufacturing costs.

One unit = 90 dollars
495 units sold last month

[tex]90\times495=44550[/tex]
[tex]=44550[/tex]

The company made 44,550 from the product last month.

Now apply the fees/costs:
2,300 dollars in monthly costs
75 dollars in manufacturing costs PER UNIT

[tex]44550-2300=42250[/tex]
[tex]75\times495=37125[/tex]
[tex]42250-37125=5125[/tex]
[tex]=5125[/tex]

Which means the company made a total profit of "$5,125 dollars" or option D last month.

Okay so basically the variables are y and x. Variables in math are just numbers next to a number to represent an unknown number. The coefficient is the number in-front of a variable. The constant would be 5. Think of constants as numbers with variables or negatives or anything. They are pretty much just there. Now as for terms.

Answer:

y = 2x + 3

Step-by-step explanation:

Get any two points on the line, say (0, 3) and (2, 7)

Slope = (7 - 3)/(2 - 0) = 4/2 = 2

y = 2x + b

use (0, 3), x = 0, y = 3

3 = b

so the equation is y = 2x + 3
