4 1/2 ounces per 3/4 miles _____ ounces per 1 mile

Mathematics
2 answers:
adelina 88 [10]3 years ago
5 0

Answer: 6

Step-by-step explanation:

To get 3/4 miles to 1 mile we must take the reciprocal of the number and multiply it.

\frac{3}{4}×\frac{4}{3} =1

We need to multiply the 4 1/2 ounces by 4/3 too

4\frac{1}{2}×\frac{4}{3} =6

4 1/2 ounces per 3/4 miles

6 ounces per 1 mile

Answer:

<h3>6 ounces</h3>

Step-by-step explanation:

Let the unknown number be x

4 \frac{1}{2}  \:  \: ounces =  \frac{3}{4} \:  \: miles  \\ x = 1 \:  \: mile

Now simply use cross multiplication to solve it

4 \frac{1}{2}  \times 1 =  \frac{3}{4} x \\  \frac{9}{2}  \times 1 =  \frac{3}{4} x \\  \frac{9}{2}  =  \frac{3x}{4}  \\

Now make x as the Subject

\frac{9}{2}  =  \frac{3x}{4}  \\  \frac{9 \times 4}{2 \times 3}  = x \\  \frac{36}{6}  = x \\ 6 = x

<em>So</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>is</em>

<h2><em>6</em><em> </em><em>ounces</em></h2>

Solve (u+6)^2+4=52 , where u is a real number.
Ugo [173]

Answer:

The value of u are,

0.93, -12.93

Step-by-step explanation:

It is given an expression in variable u

(u + 6² + 4 = 52

<u>To find the solution of given expression</u>

(u + 6)·² + 4 = 52

(u + 6)²  = 52 - 4

(u + 6)² = 48

u + 6 = √48

u + 6 = ±6.93

u =  ±6.93 - 6

u = 6.93 - 6  or u = -6.93 - 6

u = 0.93 or u = -12.93

If m∠2 = 41°, m∠5 = 94°, and m∠10 = 109°, find each measure.
Orlov [11]

Answer:

Step-by-step explanation:

It's given in this question,

m∠2 = 41°, m∠5 = 94° and m∠10 = 109°

Since, ∠2 ≅ ∠9 [Alternate interior angles]

m∠2 = m∠9 = 41°

m∠8 + m∠9 + m∠10 = 180° [Sum of angles at a point of a line]

m∠8 + 41 + 109 = 180

m∠8 = 180 - 150

m∠8 = 30°

Since, m∠2 + m∠7 + m∠8 = 180° [Sum of interior angles of a triangle]

41 + m∠7 + 30 = 180

m∠7 = 180 - 71

m∠7 = 109°

m∠6 + m∠7 = 180° [linear pair of angles]

m∠6 + 109 = 180

m∠6 = 180 - 109

        = 71°

Since m∠5 + m∠4 = 180° [linear pair of angles]

m∠4 + 94 = 180

m∠4 = 180 - 94

m∠4 = 86°

Since, m∠4 + m∠3 + m∠9 = 180° [Sum of interior angles of a triangle]

86 + m∠3 + 41 = 180

m∠3 = 180 - 127

m∠3 = 53°

m∠1 + m∠2 + m∠3 = 180° [Angles on a point of a line]

m∠1 + 41 + 53 = 180

m∠1 = 180 - 94

m∠1 = 86°

Acellus help slope intercept
Serjik [45]

Greetings.

The answer is y = 2x + 7.

Explanation:

If you are an expert in graph then you are able to find the slope without calculating. (Rise over Run by looking at the graph.)

We can also find the slope by calculating m-value.

m=\frac{y_2-y_1}{x_2-x_1}   ---> Rise Over Run

<em>But how are we gonna calculate if we don't have any two given ordered pairs?</em>

The answer is, we can just pick two ordered pairs that are part of the graph, or rather say that the graph passes through.

The graph passes through (-3,1) and (-2,3).

Then we can calculate the slope by using rise/run.

m=\frac{3-1}{-2-(-3)}\\m=\frac{2}{-2+3}\\m=\frac{2}{1}\\m=2

Thus, the slope is m = 2.

However, we are not done yet. We just only found out the slope. We need to find the y-intercept too.

From Linear Function - y=mx+b

Where m = slope and b = y-intercept.

Since b = y-intercept, we don't need to calculate/substitute x = 0. We simply find which number the graph has y-intercept at.

Which is (0,7), the y-intercept.

Then we substitute b = 7 as y-intercept.

Thus the answer is y=2x+7

I NEED HELP ASAPPP!!!! It’s urgentttttt!!!!
Akimi4 [234]

Answer: (x - 2)² + (y - 14)² = 1

Step-by-step explanation:

<u>Concept:</u>

Here, we need to know the idea of the circle formula.

Circle formula: (x - h)² + (y - k)² = r²

Center = (h, k)

Radius = r

If you are still confused, please refer to the attachment below for a graphical explanation.

<u>Solve:</u>

Center = (2, 14)

Radius = 1

<em>Given formula</em>

(x - h)² + (y - k)² = r²

<em>Substitute the value into the formula</em>

(x - 2)² + (y - 14)² = (1)²

<em>Simplify</em>

(x - 2)² + (y - 14)² = 1

Hope this helps!! :)
