m=1/2(d1+d2) (solve for d1)

Answer:

i think its 27.

Step-by-step explanation:

Let the number of pink marbles  =  p

Let the number of yellow marbles  =  y

The ratio of pink marbles to yellow marbles is 3:5 . This means...

the number of pink marbles / the number of yellow marbles  =  3 / 5

p / y  =  3 / 5

There are a total of 72 marbles in the bag. So...

the number of pink marbles  +  the number of yellow marbles  =  72

p + y  =  72

y  =  72 - p

Now we can use this value of  y  in the first equation and solve for  p .

p / (72 - p)  =  3 / 5

Multiply both sides of the equation by  5 .

5p / (72 - p)  =  3

Multiply both sides by  (72 - p)

5p  =  3(72 - p)

5p  =  216 - 3p

Add  3p  to both sides.

8p  =  216

Divide both sides by  8 .

p  =  27

the number of pink marbles  =  27

Answer:

[tex]y=\frac{-1}{3} x+4[/tex]

Step-by-step explanation:

Use the equation, [tex]y=mx+b[/tex].

'[tex]m[/tex]' will be your [tex]\frac{rise}{run}[/tex], or the slope of the equation.

'[tex]b[/tex]' is the y-intercept of the line or basically where the line touches the y axis.

The line touches the y-axis at y=4, so '[tex]b[/tex]' will be 4.

To figure out the '[tex]m[/tex]' value, count how many squares the line moves over and then how many squares it moves down.  In this case, it moves down 1 square and over three squares.  So the [tex]\frac{rise}{run}[/tex] will be [tex]\frac{-1}{3}[/tex].

To finalize the equation, you get [tex]y=\frac{-1}{3} x+4[/tex].

Answer:

18cm = 45km

Step-by-step explanation:

Divide 18 by 4 to get 4.5. Multiply 4.5 by 10 to get 45km.

Answer:

Each month he earn $1,500 a month because $4,500 divided by 3 is $1,500. So in 5 months he will make $7,500. On the 7th month he will have $10,500.

The money that the gym employee earns in 1 month will be; $1500. The money that the gym employee earns in 5 months will be; $7500.

The gym employee earns the same amount each month and after working for three months, he earned $4,500.

In this given problem, the amount that he earns monthly would be

= Total amount / Number of months

= $4500 / 3

= $1500

Thus He earns $1500 monthly.

The money that; the gym employee earns in 5 months would be:

= 5 × $1500

= $7500.

Hence, The money that the gym employee earns in 1 month will be; $1500. The money that the gym employee earns in 5 months will be; $7500.

Step-by-step explanation:

Answer:

Step-by-step explanation:

A. An equation is an identity if it can be rewritten as 0=0. Such an equation has only one​ solution, 0, and that is the identity of the variable.

B. An equation is an identity if it can be rewritten as an equation of the form ​"variable​number," such as x5 or y3. Such an equation has only one​ solution, and the solution is called the identity of the variable.

C. An equation is an identity if it can be rewritten as an equation of the form ​"variable​number," such as x5 or y3. Such an equation has an infinite number of solutions because a variable can be any number.

D. An equation is an identity if it can be rewritten as 0=0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.

Answer:

(x-y-1)^2 or [(x-y)-1]^2

Step-by-step explanation:

We are given the expression:-

[tex] \displaystyle \large{ {(x - y)}^{2} - 2(x - y) + 1 }[/tex]

Let A = (x-y)^2

[tex] \displaystyle \large{ A^{2} - 2 A+ 1 }[/tex]

From:-

[tex] \displaystyle \large{ {x}^{2} - 2x + 1 = {(x - 1)}^{2} }[/tex]

Thus:-

[tex] \displaystyle \large{ {A}^{2} - 2A + 1 = {( A- 1)}^{2} }[/tex]

Rewrite A in (x-y)^2.

[tex] \displaystyle \large{ {(x - y)}^{2} - 2(x - y) + 1 = {( (x - y) - 1)}^{2} }[/tex]

Answer:

y = 3x/2-14

Step-by-step explanation:

We are given that the line is perpendicular to y = -2/3 and contains (4,-8).

Perpendicular Def.

[tex] \displaystyle \large{m_1m_2 = - 1}[/tex]

Both slopes multiply each others equal to -1.

Finding another slope that is perpendicular to -2/3, substitite m1 = -2/3 in.

[tex] \displaystyle \large{ - \frac{2}{3} m_2 = - 1}[/tex]

Multiply both sides by 3.

[tex] \displaystyle \large{ - \frac{2}{3} m_2( 3) = - 1(3)} \\ \displaystyle \large{ - 2 m_2= - 3} \\ \displaystyle \large{ m_2= \frac{3}{2} }[/tex]

Therefore, another slope that is perpendicular to -2/3 is 3/2.

Then rewrite in slope-intercept form.

Slope-Intercept

[tex] \displaystyle \large{y = mx + b}[/tex]

where m = slope and b = y-intercept; substitute m = 3/2 in.

[tex] \displaystyle \large{y = \frac{3}{2} x + b}[/tex]

Since the line contains (4,-8), substitute x = 4 and y = -8 in and solve for b.

[tex] \displaystyle \large{ - 8 = \frac{3}{2} (4) + b} \\ \displaystyle \large{ - 8 = 3(2)+ b} \\ \displaystyle \large{ - 8 = 6 + b} \\ \displaystyle \large{ - 8 - 6 = b} \\ \displaystyle \large{ - 14 = b}[/tex]

Therefore, b is -14; rewrite again in slope-intercept form.

Thus:-

[tex] \displaystyle \large{y = \frac{3}{2} x + b} \\ \displaystyle \large{y = \frac{3}{2} x - 14}[/tex]

Using Pythagorean theorem

[tex]\\ \sf\longmapsto H^2=P^2+B^2[/tex]

[tex]\\ \sf\longmapsto H^2=11^2+6^2[/tex]

[tex]\\ \sf\longmapsto H^2=121+36[/tex]

[tex]\\ \sf\longmapsto H^2=156[/tex]

[tex]\\ \sf\longmapsto H\approx12.33[/tex]

Answer:

1st question: 30

2nd question:78

Step-by-step explanation:

use the formula [tex]A=\frac{ab}{2} sin(y)[/tex]]

Where A is the area, a and b are the two given lengths and y is the given angle.

So,

a=9

b=7

y=73

Plugging those values in, we get:

[tex]A=(\frac{9*7}{2})Sin73\\=31.5(Sin73)\\=30.1\\=30 (rounded)[/tex]

For the 2nd question, we use the same formula, only this time

a=13

b=14

y=59

so,

[tex]A=\frac{13*14}{2} sin(59)\\A=91*Sin(59)\\A=78[/tex]

15/11 is a mixed number already, it is 1.363636363636........

Answer:

[tex]1\frac{4}{11}[/tex]

Step-by-step explanation:

You can read [tex]\frac{15}{11}[/tex] as "15 divided by 11"

So to figure out the mixed number, you do just that.

11 goes into 15 1 time, then you subtract 11 from 15, which gives you a remainder of 4. You put 4 as your numerator and 11 is your denominator.

Answer:

34

Step-by-step explanation:

if you add 90+56 you get 146 and then 180-146=34

Answer:

a = 34°

Step-by-step explanation:

1. We know that the straight line is a straight angle (180°), and the right angle is worth 90°.

2. This means that a + 90 + 56 = 180.

3. (Solving equation above).

Step 1: Simplify both sides of the equation.

Step 2: Subtract 146 from both sides.

Step 3: Check if solution is correct.

Therefore, a = 34°.

Answer:

you feel happy with the process on the long division page you can skip the first bit.

divide step 1 4 ÷ 25 = 0 remainder 4 The first number of the dividend is divided by the divisor.

divide step 2 The whole number result is placed at the top. Any remainders are ignored at this point.

divide step 3 25 × 0 = 0 The answer from the first operation is multiplied by the divisor. The result is placed under the number divided into.

divide step 4 4 − 0 = 4 Now we take away the bottom number from the top number.

divide step 5 Bring down the next number of the dividend.

divide step 6 43 ÷ 25 = 1 remainder 18 Divide this number by the divisor.

divide step 7 The whole number result is placed at the top. Any remainders are ignored at this point.

divide step 8 25 × 1 = 25 The answer from the above operation is multiplied by the divisor. The result is placed under the last number divided into.

divide step 9 43 − 25 = 18 Now we take away the bottom number from the top number.

divide step 10 Bring down the next number of the dividend.

divide step 11 185 ÷ 25 = 7 remainder 10 Divide this number by the divisor.

divide step 12 The whole number result is placed at the top. Any remainders are ignored at this point.

divide step 13 25 × 7 = 175 The answer from the above operation is multiplied by the divisor. The result is placed under the number divided into.

divide step 14 185 − 175 = 10 Now we take away the bottom number from the top number.

divide step 15 Now we have reached the end of the whole numbers we add a decimal place and the first zero. Notice the decimal point which has appeared on the answer line and by the dividend. It does not appear anywhere else.

divide step 16 Bring down the next number of the dividend.

divide step 17 100 ÷ 25 = 4 remainder 0 Divide this number by the divisor.

divide step 18 The whole number result is placed at the top. Any remainders are ignored at this point.

divide step 19 25 × 4 = 100 The answer from the above operation is multiplied by the divisor. The result is placed under the number divided into.

divide step 20 100 − 100 = 0 Now we take away the bottom number from the top number.

divide step 21

The subtraction has given zero. We stop when this happens. The answer is 17.4

As long as the subtraction gives a number above zero the long division can carry on to as many decimal places as we wish.
