Answer:

11/8 is the answer as a fraction

The fraction value of 7/8+1/2 is 11/8

Fraction is a numerical value which has two parts. The bottom part is called denominator which indicates the no. of parts in which the whole is divided. And the top part is called numerator which indicates how many parts of the fraction are selected.

Example : 2/3 , where 2 is the numerator and 3 is the denominator.

The given sum is, [tex]\frac{7}{8}+\frac{1}{2}[/tex]  

Taking LCM of 8 & 2, which is 8,

                          = [tex]\frac{(7*1)+(1*4)}{8}[/tex]

                           = [tex]\frac{7+4}{8}[/tex]

                            = [tex]\frac{11}{8}[/tex]

∴ The required fraction is [tex]\frac{11}{8}[/tex]

Answer:

C

Step-by-step explanation:

The triangular inequality states that a+b>c, b+c>a, a+c>b. So, 4+8=12, so a is not possible. Neither is b. D is not true either. It has to be c.

The third side of the triangle measures more than 4 inches.

According to the given question we have,

Length of the two sides of a triangle are 8 inches and 12 inches.

Let the length of the third side be x inches.

Now, according to the properties of a triangle

"The difference between the two sides of a triangle is less than the length of the third side".

Therefore,

12 - 8 < x

⇒ 4 < x

⇒ The third side of the triangle is greater than 4 inches.

Hence, the third side of the triangle measures more than 4 inches.

Answer:

B) 7

Step-by-step explanation:

Subtract 11 by both sides

3x - 4(x + 1) + 11 - 11 = 0 - 11

Simplify

3x - 4(x + 1) = -11

Distribute 4

3x - 4x - 4 = -11

Add 4 to both sides and combine like terms

-x - 4 + 4 = -11 + 4

-x = -7

Divide both sides by -1

x = 7

Step-by-step explanation:

If she gets 6 slices from each apple, then for A(which is 0 apples) you would get 0 slices. For B (which is 1 apple.) you would get 6 slices and for C (which is two apples) you would get 12 slices. I hope this helps!

Answer:

a=0

b=6

c=12

Step-by-step explanation:

4:24 is one of the ratios

lets use that as an example

divide both sides by 4 and you get

1:6

now lets use 3:18

divide both sides by 3 and you get

1:6

Now if you have 0 apples you have 0 slices

if you have one apple you get 6 slices...

because of the ratio 1:6 one apple=6 slices

now if you have 2 apples you have to times 1:6 by 2 which gives us 2:12 meaning you get 12 slices

Answer:

[tex]2.42\,oz \leq m_{real} \leq 2.58\,oz[/tex]

Step-by-step explanation:

The inequality must be the absolute value of the difference between real mass and ideal mass less or equal to 0.08 ounces. That is to say:

[tex]|m_{real} - m_{ideal}| \leq 0.08\,oz[/tex]

[tex]|m_{real} - 2.5\,oz| \leq 0.08\,oz[/tex]

There are two extreme cases:

[tex]m_{real,max} - 2.5\,oz = 0.08\,oz[/tex] and [tex]m_{real, min} - 2.5\,oz = -0.08\,oz[/tex]

[tex]m_{real, max} = 2.58\,oz[/tex] and [tex]m_{real,min} = 2.42\,oz[/tex]

Answer:

Dodgers won 73 games while angels won 73 + 19 = 92  games.

Step-by-step explanation:

The Dodgers and the angels won a total of 165 games during a regular season. The angels won 19 games more than the Dodgers .

The both team won a total of  165 games but we weren't given the game each team won but the game each team won can be gotten from the question.

Let

number of game won by Dodgers = x

number of game Angels won = x + 19

The both of them won 165 game altogether. This means the sum of their individual games won is equals to 165. Therefore,

x + x + 19 = 165

collect like terms

2x + 19 = 165

2x = 165 - 19

2x = 146

divide both sides by 2

x = 146/2

x = 73

Dodgers won 73 games while angels won 73 + 19 = 92  games.

Answer:

slope of the tangent

[tex]\frac{d y}{d x} = 0.2(2 x) + 5 (1)[/tex]

The slope of the tangent to the interval (-1 ,1)

m = 4.6 ,5, 5.4

Step-by-step explanation:

Step(i):-

Given function is  f(x) = 0.2 x² + 5 x − 12

Slope of the tangent formula

                        [tex]m = \frac{d y}{d x}[/tex]

Let y =  f(x) = 0.2 x² + 5 x − 12 ...(i)

Differentiating equation(i) with respective to 'x' , we get

[tex]\frac{d y}{d x} = 0.2(2 x) + 5 (1) -0[/tex]

let x=-1

[tex]m = \frac{dy}{dx} = 0.2 (2 X -1) +5 = 4.6[/tex]

let x=0

m = 5

let x=1

[tex]m = \frac{dy}{dx} = 0.2 (2 X 1) +5 = 5.4[/tex]

conclusion:-

slope of the tangent

[tex]\frac{d y}{d x} = 0.2(2 x) + 5 (1)[/tex]

The slope of the tangent to the interval (-1 ,1)

m = 4.6 , 5,  5.4

The x-values at which the slope of the tangent line to the function f(x) belongs to the interval (-1, 1) are x ∈ (-15, -10).

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

To find the x-values at which the slope of the tangent line to the function f(x) = 0.2x² + 5x − 12 belongs to the interval (-1, 1), we need to find the x-values at which the derivative of the function f(x) has a value within that interval.

The derivative of f(x) is given by f'(x) = 0.4x + 5. Therefore, we can find the x-values at which f'(x) belongs to the interval (-1, 1) by solving the inequality 0.4x + 5 ∈ (-1, 1).

To solve this inequality, we can rewrite it as follows:

-1 < 0.4x + 5 < 1

-1 - 5 < 0.4x < 1 - 5

-6 < 0.4x < -4

Dividing both sides of the inequality by 0.4, we get:

-15 < x < -10

Therefore, the x-values for which the slope of the tangent line to the function f(x) lies x ∈ (-15, -10).

∠ 5 = 40°

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and supplementary, thus

∠ 2 = 180° - ∠ 1 = 180° - 140° = 40°

∠ 5 and ∠ 2 are alternate angles and congruent , thus

∠ 5 = 40°

Answer:

10.1 years.

Step-by-step explanation:

It is given that,

Principal = 9000

Rate of interest = 5%

No. of times interest compounded = 2 times in an year

Amount after certain time = 14800

The formula for amount:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

where, P is principal, r is rate of interest, n is no. of times interest compounded in an year and t is time in years.

Substitute the given values in the above formula.

[tex]14800=9000(1+\frac{0.05}{2})^{2t}[/tex]

[tex]\frac{14800}{9000}=(1+0.025)^{2t}[/tex]

[tex]1.644=(1.025)^{2t}[/tex]

Taking log both sides.

[tex]\log(1.644)=\log(1.025)^{2t}[/tex]

[tex]\log(1.644)=2t\log(1.025)[/tex]    [tex][\because \log a^b=b\log a][/tex]

[tex]\frac{\log(1.644)}{2\log(1.025)}=t[/tex]

[tex]t=10.066[/tex]

[tex]t=10.1[/tex]

Therefore, the required time is 10.1 years.
