Write an equation for the line that has a slope of 1/2 and passes though the point (-2,5)?

Answer:

The common denominator is 15.

2 3/5 = 13/5 = 39/15

1 1/3 = 4/3 = 20/15

Answer:

39/15 and 20/15

Step-by-step explanation:

Given function:

Rewrite 2 3/5 and 1 1/3 by a number that is equivalent to 5 and 3:

Multiply each numerator by how much times it turned into 15:

Simplfly the fraction terms:

Therefore, 39/15 and 20/15 is equivalent to 2 3/5 and 1 1/3.

Answer:

1232 is the volume because 16×7×11

Answer:

The volume is 1,232 ft³

Step-by-step explanation:

Volume = lwh = Length × Width × Height =

[given that the length is 16, width is 7, and height is 11]

16 × 7 × 11

4 × 4 × 7 × 11

2 × 2 × 2 × 2 × 7 × 11

2 × 2 × 2 × 2 × 77

2 × 2 × 2 × 154

2 × 2 × 308

2 × 616

1232

________

The volume is the measurable capacity of an object or the metrical space that something holds or takes up.

Just like you multiply the net length and width to find the area of a 2 dimensional object, you can extend that 2d object so that is has height by multiplying by the given height.

Answer:

Step-by-step explanation:

1. 2x - 9y = 23

2 x = 9 y + 23

y = (2 x)/9 - 23/9

2 x - 9 y - 23 = 0

2. 5x - 3y = -1

5 x + 1 = 3 y

y = (5 x)/3 + 1/3

5 x - 3 y + 1 = 0

I belive that should help you out a bit :D

Step-by-step explanation:

Answer:

The cost of the washing machine is P 3,544

The mark-up rate is 35.21%

Step-by-step explanation:

1. We want to calculate the cost

Mathematically, this is the difference between the selling price and the mark up

We have this as;

4,792 - 1,248 = P 3,544

2. Here, we want to calculate the mark-up rate

Mathematically, this is the percentage of mark-up

That is;

mark-up/cost price * 100%

: 1,248/3,544 * 100% = 35.21%

Answer:

Answer:

That is an obtuse scalene triangle

Step-by-step explanation:

Scalene- has no congruent sides

Obtuse - has an angle that is greater than 90

we can use Pythagorean theorem to confirm this

The Pythagorean theorem states that in an obtuse triangle the hypotenuse squared is greater than the two legs squared added together

so basically [tex]7^2>4^2+5^2\\7^2=49\\4^2=25\\5^2=25\\25+16=41\\49>41[/tex]

therefore it is an obtuse scalene

Answer:

(Choice E) E Scalene triangle and (Choice F) F Obtuse triangle

Step-by-step explanation:

Aside from E, Scalene triangle (as all the sides are of different lengths, we can assume that the angles will also be), the answer can either be B, Isosceles triangle or F, Obtuse triangle, so let's figure that out using the cosine rule! If it is an obtuse triangle, this means Angle ABC is bigger than Angle BAC and Angle BCA. But we can clearly see it is, as it's an Obtuse Triangle is a triangle where 1 angle is bigger than 90 degrees. Let's work out Angles BAC and BCA to find out if the triangle is obtuse or isosceles.

[tex]a^{2} = b^{2} +c^{2} -2bcCosA[/tex]  This is the cosine rule formula. Now all we need to do is substitute in the values. We are using the cosine rule because we aren't given any angle values. We use Further Trigonometry instead of SOHCAHTOA as this clearly isn't a right-angled triangle. SOHCAHTOA only applies to triangles with a 90 degree angle, also known as a right-angled triangle. Let's rearrange the cosine formula so that we have everything equal to A instead.

[tex]A = cos^{-1}(\frac{b^{2} + c^{2} - a^{2} }{2bc})[/tex]

We will work out BAC first.

a = 5

b = 4

c = 7

[tex]A = cos^{-1}(\frac{4^{2} + 7^{2} - 5^{2} }{2(4)(7)})[/tex]

A = 44.4 rounded to 3 significant figures

Next, we will work out BCA.

a = 4

b = 5

c = 7

[tex]A = cos^{-1}(\frac{5^{2} + 7^{2} - 4^{2} }{2(5)(7)})[/tex]

A = 34.0 rounded to 3 significant figures

The answer is F, Obtuse triangle and E, Scalene triangle

If we just worked out BAC, we would have noticed that by assuming BCA was also 44.4, the obtuse angle would be 91.2 degrees, which is barely above 90 degrees, therefore we would have correctly guessed the triangle as obtuse from there-on. I just worked out BCA as evidence to support that Triangle ABC cannot be isosceles, therefore we can eliminate that option and classify this triangle as Obtuse.

I hope my explanation helps!!

Answer:

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Step-by-step explanation:

Geometrically speaking, the perimeter of a rectangle ([tex]p[/tex]) is:

[tex]p = 2\cdot b + 2\cdot h[/tex] (1)

Where:

[tex]b[/tex] - Base of the rectangle.

[tex]h[/tex] - Height of the rectangle.

Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:

[tex]b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}[/tex]

[tex]b = 5[/tex]

If we know that [tex]p = 18[/tex] and [tex]b = 5[/tex], then the height of the rectangle is:

[tex]2\cdot h = p-2\cdot b[/tex]

[tex]h = \frac{p-2\cdot b}{2}[/tex]

[tex]h = \frac{p}{2}-b[/tex]

[tex]h = 4[/tex]

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Answer:

Javon purchase Energy cards = 52

Javon purchase Dragon cards = 75

Step-by-step explanation:

Given - Javon spent $687 on pokemon cards. Energy cards cost $6

             and dragon cards cost $5.

To find - If he bought a total of 127 packs then how many of each did he buy ?

Proof -

Let Javon purchase Energy cards = x

     Javon purchase Dragon cards = y

Now,

Given that he bought a total of 127 packs

⇒x + y = 127

Also,

Cost for 1 Energy card = $6

⇒Cost of x Energy cards = $ 6x

And

Cost of 1 Dragon card = $5

⇒Cost of y Dragon card = $ 5y

Now,

Given that Javon spent $687 on pokemon cards.

⇒6x + 5y = 687

∴ we get

x + y = 127                                 ..................(1)

6x + 5y = 687                            .................(2)

Multiply by 6 in equation (1) , we get

6(x + y) = 6(127)

⇒6x + 6y = 762                          .................(3)

Now,

Subtract equation (2) from equation (1) , we get

6x + 6y - (6x + 5y )= 762 - 687

⇒6x + 6y - 6x - 5y = 75

⇒y = 75

Now,

Put the value of y in equation (1), we get

x + 75 = 127

⇒x = 127 - 75

⇒x = 52

∴ we get

Javon purchase Energy cards = x = 52

Javon purchase Dragon cards = y = 75
