Answer: t= 3/2

Step-by-step explanation: 5/ 7 1/2 = 3/2

Answer:

t = 7/10 = 0.700

Step-by-step explanation:

STEP

:

           1

Simplify   —

           2

Equation at the end of step

1

:

            1

 5t -  (7 • —)  = 0

            2

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  2  as the denominator :

          5t     5t • 2

    5t =  ——  =  ——————

          1        2  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

5t • 2 - (7)     10t - 7

————————————  =  ———————

     2              2  

Equation at the end of step

2

:

 10t - 7

 ———————  = 0

    2  

STEP

3

:

When a fraction equals zero :

3.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 10t-7

 ————— • 2 = 0 • 2

   2  

Now, on the left hand side, the  2  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  10t-7  = 0

Solving a Single Variable Equation:

3.2      Solve  :    10t-7 = 0

Add  7  to both sides of the equation :

                     10t = 7

Divide both sides of the equation by 10:

                    t = 7/10 = 0.700

One solution was found :

t = 7/10 = 0.700

Answer:

140

Step-by-step explanation:

1 and 3 are vertical angles meaning they are equal. 4 and 3 make a straight angle. A straight angle is 180.

180-140=40

2 and 4 are straight angles so should be equal.

1=140

2=40

3=140

4=40

Answer: The first step would be to subtract 32 from both sides.

Step-by-step explanation:

The answer to the whole equation is -44.

To get -44 you need to get rid of the 32 to get the x to be alone.

Answer:

1.8 KMH

Step-by-step explanation:

to get the meters per second, simply divide the meters by the seconds. 4.5/9= .5

now, to convert from meters per second to kilometers per hour, multiply the meters per second by 3.6.

.5 x 3.6 = 1.8

Answer:

1.8 km/h

Step-by-step explanation:

Use dimensional analysis:

4.5m/9sec x 0.001km/1m x 3600sec/1hour=

Answer   -2-

Step-by-step explanation:

Using it's concept, it is found that the median of the data in the dot plot is 83.5.

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.

The dot plot gives the number of times each measure appears, hence in this problem, the data-set is composed by:

{81, 82, 83, 83, 84, 84, 85, 85}

Even cardinality, hence the median is the mean of the two middle elements, 83 and 84, hence:

M = (83 + 84)/2 = 83.5.

The median of the data in the dot plot is 83.5.

The Domain is x>-7 or C

The Range is x>5 or b

Step-by-step explanation:

edge

The domain of the function y = √(x+7) + 5 is [-7, ∞).

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The given equation is y = √(x+7) + 5.

For the expression under the square root to be non-negative, we must have x + 7 ≥ 0.

The domain of the function is all real numbers greater than or equal to -7.

Thus,

The domain of the function y = √(x+7) + 5 is [-7, ∞).

28.5cm^2

Answer:

= 28.5cm²

Step-by-step explanation:

A is a full diamond which is equal to 3cm²

B has: 7 full diamonds and five 1/2 diamonds

Five 1/2 diamonds = 2 full diamonds and 1/2 a diamond.

If 1 diamond(A) = 3cm²

What about 9 diamonds = ?

= (9 × 3) ÷1

= 27cm²

If 1 diamond(A) = 3cm²

What about 1/2 a diamond = ?

= 1/2 × 3

= 1.5cm²

Total = 27 + 1.5

Using it's formula, it is found that the Mean Absolute Deviation is given by:

D.4.24

In this problem, the mean is given by:

[tex]M = \frac{5 + 11 + 2 + 7 + 16}{5} = 8.2[/tex]

Hence, the mean absolute deviation is given by:

[tex]M_d = \frac{|5-8.2| + |11-8.2| + |2-8.2| + |7-8.2| + |16-8.2|}{5} = 4.24[/tex]

Answer:

75 degrees

Step-by-step explanation:

3x+15 = 4x - 5

-3x       -3x

15=x-5

+5    +5

x=20

4(20)-5 = 75

Answer:

75

Step-by-step explanation:

1 and 2 are corresponding angles meaning that they are equal to each other or congruent

so we set up an equation

4x-5=3x+15 and since for x

step 1 subtract each side by 3x

4x-3x=x

now we have

x-5=15

step 2 add 5 to each side

5+15=20

x=20

now we just plug in 20 to 4x - 5

4x20=80

80-5=75

therefore your answer is 75
