Answer:

[tex]13\frac{43}{64}[/tex]

Step-by-step explanation:

We can see the numerator is being multiplied by 3 and the denominator is being multiplied by 4.

[tex]\frac{45*3}{16*4} =\frac{135}{64}[/tex]

Then we will add them,

[tex]5 + \frac{15}{4}+\frac{45}{16} +\frac{135}{64} becomes \frac{320}{64} +\frac{240}{64} +\frac{180}{64} +\frac{135}{64}=\frac{875}{64} =13\frac{43}{64}[/tex]

You can also use formulas to solve this as well, but this way should work too as there are not very many terms :)

Have a nice day!

Answer:

B is the answer.

Step-by-step explanation:

Im just smart.

Answer:

370 000

As it varies directly we know the values are directly proportional.

This means we can calculate the ratio of people to tons of pollutants and apply it to 500 000

So, 29600/40000= 0.74

Now, 500 000 × 0.74 = 370000

Answer: 370000 t

Step-by-step explanation:

[tex]40000 ~p - 29600 ~ t \\\\ 500000 ~ p- x ~ t \\\\ x=\dfrac{500000\cdot 29600}{40000}=\dfrac{50\cdot 29600}{4} =7400\cdot 50 =\bf 370000 \ t[/tex]

Step-by-step explanation:

Realize that:

speed = distance / time and thus

time = distance / speed

Then the whole journey of 40/60 hours is the sum of (let's call them t1 and t2)

cycling: t1 = 2/y hours

running: t2 = 4/(y-4) hours

so we must simplify t1+t2=40 minutes (a.k.a. 4/6 hours):

2/y + 4/(y-4) = 4/6

let's multiply the first term by (y-4)/(y-4) and the second term by (y/y):

[tex]\frac{2(y-4)}{y(y-4)} + \frac{4y}{y(y-4)} = \frac46[/tex]

since they now share a common denominator:

[tex]\frac{2(y-4) + 4y}{y(y-4)} = \frac46[/tex]

[tex]\frac{6y-8}{y(y-4)} = \frac46[/tex]

cross-products:

[tex]6 (6y-8) = 4y(y-4)[/tex]

further simplification:

[tex]36y - 48 = 4y^2 - 16y[/tex]

[tex]4y^2 - 52y + 48 = 0[/tex]

[tex]y^2 - 13y + 12 = 0[/tex]

Step-by-step explanation:

the last one is "Each point (or pair) in a proportional relationship must share the same difference."

Answer:

Step-by-step explanation:

Given :  Statement about proportional relationships  

To Find : Which statement is False

Solution:

proportional relationships

y ∝ x

=> y = kx    

Comparing with line line of equation

y = mx + c

m = k  , c = 0

Hence A proportional relationship must graph as a line

TRUE

at x = 0 , y = 0

Hence graph of a proportional relationship must pass through (0, 0).

TRUE

y = kx  

=> y/x = k  hence

Each point (or pair) in a proportional relationship must share the same ratio.

Each point (or pair) in a proportional relationship must share the same difference.

I hope you can follow the formula and solution.

Hello there.

To answer this question, we need to remember some properties about the vertex of quadratic functions.

Let [tex]f(x)=ax^2+bx+c,~a\neq0[/tex]. Its vertex can be found on the coordinates [tex](x_v,~y_v)[/tex] such that [tex]x_v=-\dfrac{b}{2a}[/tex] and [tex]y_v=-\dfrac{b^2}{4a}+c[/tex], in which [tex]y_v=f(x_v)[/tex].

Using the coefficients given by the question, we get that:

[tex]x_v=-\dfrac{8}{2\cdot(-1)}\\\\\\ x_v=-\dfrac{8}{-2}\\\\\\ x_v=4[/tex]

Thus, we have:

[tex]y=f(x_v)=f(4)[/tex]

So the statement is true, because the [tex]x[/tex] coordinate of the vertex of the function is equal to [tex]4.~~\checkmark[/tex]

The solution is A = 10

The value of the equation A = a + 10 , when a = 7 is A = 10

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = a + 3   be equation (1)

when a = 7

Substitute the value of a = 7 in the equation , we get

A = 7 + 3

On simplifying the equation , we get

The value of A = 10

Therefore , the value of A is 10

Hence , the equation is A = 10

Answer:

35

Step-by-step explanation:

Because X=5, the equation is literally just asking 5x5=10. So, following the order of operations, I would do 5x5 first which equals 25 plus 10. Since 25+10=35.  The answer is 35. Hope this helps! :p

Answer:

The absolute value of any number (positive or negative) is always positive.

h+8=15

Subtract 8 from both sides.

h=7

:)

Answer:

7

Step-by-step explanation:

absolute value means the distance from zero.

the absolute value of -8 is 8 because it is 8 units away from 0.

thus, the equation can be written as h+8=15.

h=7 because 15-8=7

Answer:

x = 36°, 2x° = 72°, 3x° = 108°, and 4x° = 144°

Step-by-step explanation:

Given the quadrilateral in which the sum of its four angles is 360°.

We can establish the following formula to find the value of x, and determine the measures of each angle:

x° + 2x° + 3x° + 4x° = 360°

Combine like terms:

10x° = 360°

Divide both sides by 10 to solve for x:

[tex]\mathsf{\frac{10x^{\circ}}{10}\:=\: \frac{360^{\circ}}{10}}[/tex]

x = 36°

Substitute the value of x into each unknown angle measures:

x = 36°

2x° = 2(36)° = 72°

3x° = 3(36)° = 108°

4x° = 4(36)° = 144°

Verify whether the sum of the previously unknown angle measures equal 360°:

x° + 2x° + 3x° + 4x° = 360°

36° + 72° + 108° + 144° = 360°

360° = 360° (True statement).

Therefore, the following are the angle measures of the given quadrilateral: x = 36°, 2x° = 72°, 3x° = 108°, and 4x° = 144°

6(x + 4) = 20

6x + 24 = 20

6x = 20 - 24

6x = -4

x = -4/6

x = -2/3

Answer:

⅔

Step-by-step explanation:

6(x + 4) = 20

(6 . x) + (6 . 4) = 20

6x + 24 = 20

6x = 20 - 24

6x = (-4)

x = (-4)/6

x = - ⅔

Answer:

x = 5

Step-by-step explanation:

For A to be parallel to B

the alternate exterior angles must be equal

Subtract 9x from both sides

4x - 8 = 12

add 8 to both sides

4x = 20

Divide both sides by 4

x = 5

Answer:

6m-27

Step-by-step explanation:

The equivalent expression of 9(4/3m- 5 - 2/3m + 2) is 6m/3 - 27.

The correct option is C.

Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).

Given;

The expression 9(4/3m- 5 - 2/3m + 2).

To find the equivalent expression:

Simplifying,

9(4/3m- 3 - 2/3m)

= 9(4m/3 - 2m/3 -3)

= 9{(4m-2m)/3 -3}

= 9 {2m/3 - 3}

= 6m/3 - 27.

Therefore, 6m/3 - 27 is the equivalent expression.

Answer:

m<H = 59°

Step-by-step explanation:

Use the theorem on the measure of an exterior angle of a triangle.

5x + 17 + 6x - 1 = 126

11x + 16 = 126

11x = 110

x = 10

m<H = 6x - 1

m<H = 6(10) - 1

m<H = 60 - 1
