Answer:

ans 12

Step-by-step explanation:

first term(a)=89

common difference(d)=7

we know,

tn=a+(n-1)d

t12=89+(12-1)(-7)

t12=89+11*(-7)

t12=89-77

t12=12

Answer:

n = -1.825

Step-by-step explanation:

8n + 16.2 = 1.6 (Given)

8n = -14.6 (Subtract 16.2 on both sides)

n = -1.825 (Divide 8 on both sides)

Answer:

Step-by-step explanation:

2x -5y = -6 === (1)

4x-3 =-12 ====(2)

From (2), 4x= -12 +3

               4x= -9

                 x= -2[tex]\frac{1}{4}[/tex]

Subst x= -2[tex]\frac{1}{4}[/tex] in (1), 2(-2[tex]\frac{1}{4}[/tex]) - 5y = -6

                              -4[tex]\frac{1}{2}[/tex] -5y = -6

                                    -5y = -6 +4[tex]\frac{1}{2}[/tex]

                                    -5y = -1[tex]\frac{1}{2}[/tex]

                                       y = 0.3

[tex]y = mx + b \\ m = slope \\ b = y - intercept[/tex]

[tex] \begin{cases}(x_1,y_1) = ( - 4,0) \\ (x_2,y_2) = ( 0,2) \end{cases}[/tex]

These two coordinate points are part of the graph and can be used to find the slope.

[tex]m = \frac{y_2 -y_1 }{x_2 - x_1} [/tex]

Substitute the coordinate points in the formula.

[tex]m = \frac{2 - 0}{0 - ( - 4)} \\ m = \frac{2}{ 4} \\ m = \frac{1}{2} [/tex]

Therefore, the slope is 2.

Rewrite the equation in slope-intercept.

[tex]y = \frac{1}{2} x + b[/tex]

[tex](x,y) = ( 0,2)[/tex]

I will be substituting these coordinate points in the equation.

[tex]y = \frac{1}{2} x + b[/tex]

Substitute x = 0 and y = 5 in the equation.

[tex]2 = \frac{1}{2} (0) + b \\ 2 = 0 + b \\ 2 = b[/tex]

Therefore the y-intercept is (0,2).

Rewrite the equation.

[tex]y = \frac{1}{2} x + 2[/tex]

[tex] \large \boxed{y = \frac{1}{2} x + 2}[/tex]

Answer:

40

Step-by-step explanation:

because 95/100 x 38/1 = 40

The number of total questions in the quiz if, Helen got a 95% on her math quiz. She had 38 questions right is 40.

A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.

Given:

Helen got a 95% on her math quiz,

The number of right questions = 38,

Calculate the total number of questions as shown below,

Percentage = The number of right questions / Total number of questions × 100

95 = 38 / x × 100

x = 38 / 95 × 100

x = 0.4 × 100

x = 40

Thus, the total number of questions is 40.

Step-by-step explanation:

[character limit thing]

Answer:We will consider the price of the truck to be $x

And the amount of tax in the percentage would be 13%

13/100

= $ 0.13x (this is the actual amount of the tax)

Now we will calculate the total price of the truck =

$x + $ 0.13x

= $ x(1 + 0.13)

Step-by-step explanation:

Answer:

85

Step-by-step explanation:

basically you throw away the whole equation and are left with the equal sign.

Now the equal sign is equal to every thing and anything.

So you could most likely say 2=3 and break the laws of time and matter itself.

I wouldn't try this at home since you'll most likely create a black whole the size of Wisconsin and destroy the world as we know it.

Answer:

32.36

Step-by-step explanation:

Trust me im right

2 5/3 raised to the third power

first you change the mixed fraction to an improper fraction you'll get 11/3

11/3 raised to the third power is the same thing as 11³/3³=1331/27= 49 8/27

Given:

[tex]\to (2 \frac{5}{3})^3[/tex]

To find:

value=?

Solution:

[tex]\to (2 \frac{5}{3})^3[/tex]

solving the mixed fraction value into the fraction:

[tex]\to (\frac{11}{3})^3\\\\[/tex]

diving the value

[tex]\to (3.66666667)^3\\\\\to 49.2962964\approx 49.3[/tex]

Answer: i think that the only fraction that we can convert this into is 2111/1000

Answer:

[tex]\frac{2111}{1000}[/tex]

Step by step:

2.111 = [tex]\frac{2.111}{1}[/tex]

then, get rid of the decimal sign in 2.111 by multiplying it by 1000 since there are 3 numbers after the decimal point.

your new fraction is [tex]\frac{2111}{1000}[/tex]

Answer: x/2

Step-by-step explanation:

Combine x and 1/2

The expression (1/2)x is equivalent to the expression 0.5x. Then the correct option is A.

The equivalent is the expression that is in different forms but is equal to the same value.

Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to answer the problem correctly and precisely.

The expression is given below.

⇒ (1/2)x

Simplify the expression, then we have

⇒ (1/2)x

⇒ 0.5x

The expression (1/2)x is equivalent to the expression 0.5x. Then the correct option is A.

Answer:

609 bags

Step-by-step explanation:

( times 60.83333 )1 bag of dog food : 6 days   (365/6=60.833333)

        60.83333 bags=                     365 days ( 1 year)

         608.3333 bags                                                   10 years

you need to round it up because you cannot  have a half part of a bag.

609 bags

please mark it as brainliest!!

The number of bags that will be eaten in 1 year and 10 years respectively will be 61 bags and 608 bags.

From the information given, Laura’s dog eats 1 bag of dog food every 6 days. The number of bags that her dog will eat in 1 year will be:

= 365/6

= 60.8 = 61 bags.

Therefore, the number of bags that will be eaten in 10 years will be:

= 60.8 × 10 = 608 bags.
