Please give me brainliest I would appreciate it

The sides of a triangle are in the ratio 1 : 2 : 4. The difference between the longest side and the shortest side is 84 cm. What is the perimeter of the triangle ?

The sides of a triangle are in the ratio 1: 2: 4. (Given)

Let the three sides of a triangle be x, 2x and 4x respectively.

So,

ATQ ,

4x - x = 84

3x = 84

x = [tex] \bf \frac{84}{3} [/tex]

[tex] \therefore [/tex] Longest side = 4x = 4 × 28 = 112 cm.

Shortest side = x = 28 cm.

And, the other side = 2x = 2 × 28 = 56 cm

Now, we have to find the perimeter of the triangle.

Hence, Perimeter of the triangle = (112 + 56 + 28) cm = 196 cm.

Answer:

x = 5

Step-by-step explanation:

These angles are supplementary so:

9x + 12x + 75 = 180

21x + 75 = 180

21x = 180 - 75

21x = 105

x = 5

Answer:

(b)

Step-by-step explanation:

Given

A roll of a six sided die

Required

Which of the options is true

A) P(Even) = 1/4 and P(Odd) = 3/4

In a die, we have:

[tex]S = \{1,2,3,4,5,6\}[/tex] -- sample space

[tex]E = \{2,4,6\}[/tex] --- Even

[tex]O = \{1,3,5\}[/tex] -- Odd

The probability of even is the number of even sides over total.

i.e.

[tex]P(Even) = 3/6[/tex]

[tex]P(Odd) = 3/6[/tex]

Hence, (a) is incorrect

(b) A) P(Even) = 1/2 and P(Odd) = 3/2

In (a), we have:

[tex]P(Even) = 3/6[/tex]

[tex]P(Odd) = 3/6[/tex]

Simplify each

[tex]P(Even) = 1/2[/tex]

[tex]P(Odd) = 1/2[/tex]

Hence (b) is true

Since (b) is true, (c) and (d) are false

Answer:

729

Step-by-step explanation:

Answer:

450 miles

Step-by-step explanation:

First you calculate miles per gallon, which you do by dividing 300/20. This gives us 15. So you can go 14 miles on one gallon.

From there you multiply 15 by 30, since you'll be driving 30 miles. This gives us 450 miles.

Step-by-step explanation:

[tex] \frac{300}{x} \times \frac{20}{30} = \frac{20x}{20} \frac{9000}{20} x = 450miles[/tex]

Answer:

B

Step-by-step explanation:

7x + 1 isn't equal to 8x

For example:

Addition. In this equation, you can add all of the coefficients (2, 5, and 4) because the variables are the same (a).

2a + 5a + 4a = 11a

Subtraction. In this equation, you can subtract all of the coefficients (11, 5, and 4) because the variables are the same (a).

11a – 5a – 4a = 2a

Answer:

So, L'Hospital's Rule tells us that if we have an indeterminate form 0/0 or ∞/∞ all we need to do is differentiate the numerator and differentiate the denominator and then take the limit. (Brainliest? :3)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use the distance formula between points to find all sides:

[tex]d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]

AB=[tex]\sqrt{13}[/tex]

BC=[tex]\sqrt{13}[/tex]

CA=[tex]\sqrt{26}[/tex]

This is a 45° 45° 90° triangle, where two of the sides are equal and the other side is the first two sides times [tex]\sqrt{2}[/tex], so yes, it is a right triangle.

Answer:

Answer D is correct.

Step-by-step explanation:

By inspection, the side lengths are {3, 4, 5}, and this triplet satisfies the Pythagorean Theorem:  3^2 + 4^2 = 5^2.  Thus this IS a right triangle.  

One could also find the lengths of the three sides using the distance formula and the endpoints of each line segment forming the triangle.

Answer D is correct.

Answer:

It would take 4 quarts of 5% buttermilk and 41 quarts of 2% buttermilk to make 45 quarts of 3% buttermilk.

Step-by-step explanation:

Let the number of 5% quarts = x

Let the number of 2% quarts = y

x+y=45

y=45-x

(.05)x+(.02)y=(0.03)45

5x+2y=102

5x+2(45-x)=102

5x+90-2x=102

3x=12

x=4

y=45-x=45-4=41

So it would take 4 quarts of 5% buttermilk and 41 quarts of 2% buttermilk to make 45 quarts of 3% buttermilk.
