x፡y =1:2and y:z =3:2 then what is the value of x and y ?​

Answer:

q = 15

Step-by-step explanation:

→First, add 18q to both sides:

-15 - 18q = -20q + 15

-15 = -2q + 15

→Subtract 15 from both sides:

-30 = -2q

→Divide both sides by -2:

15 = q

We first want to get q on its own then solve like shown:

-15-18q=-20q+15

Now add 15 to both sides and add 20 q to both sides.

2q=30

Now divide 30 by 2.

q=15

Answer:

-(3x-5) (x-4)

Step-by-step explanation:

-3x^2+17x-20

Factor -1 out of -3x^2

-(3x^2)+17x-20

Factor -1 out of 17x

Answer: 3 inches

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:  

Volume of a cone = 1/3 x π x radius^2 x height  

Replacing with the values given:  

75 = 1/3(3.14) r^2 (6)  

Solving for r:

75 / (1/3 (3.14) 6) = r^2

75/ 6.28 = r^2

11.94 = r^2

√11.94 =r

3.45 inches = r

3 inches = r

Feel free to ask for more if needed or if you did not understand something.  

Start by subtracting 2 from both sides.

This gives us -3x < 9.

Now, divide both sides by -3.

However, when you divide both sides of an inequality by a negative number, you must switch the direction of the inequality sign.

So we have x > -3.

Answer:

It is growth and the percentage rate of increase is 7.5%

Step-by-step explanation:

The exponential equation is as follows;

y = 550(1.075)^x

Now, I can identify that the exponential equation is that of growth.

This is because what is in the bracket i.e can be represented as 1+ 0.075

The 0.075 represents the margin of increase as we move on from one value to another

The percentage rate can be gotten by expressing 0.075 as a percentage

That would be expressing is as a fraction

This is just 7.5/100 which means what we have is 7.5%

Answer:

True

Step-by-step explanation:

Example: sqrt(5) (which decimals continue forever) will mean that if you did 5+sqrt(5) it would still have those decimals.

Answer:

True. By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal, so the result is irrational.

Answer:

Change in temperature was 12 degrees

Step-by-step explanation:

If you start with five degrees and end into negative 7 degrees, you can find the result within two steps

5 degrees minus 5 = 0 degrees

then, 0 degrees minus 7 = -7 degrees

Because you subtracted 5 from five, and 7 from seven, you add those two values together

7 + 5 = 12 degrees

So the change in temperature was 12 degrees

Answer:

V≈2,080cm^3  Hope I helped :)

Step-by-step explanation:

The volume of a cone of radius r and height h is:

V=1/3πr^2h

Since the circumference of Cam's head is 56

2πr=56

r=56/2π

r=28/π

The volume of the hat is therefore:

​V=1/3π(28/π )^2(25)

V=1/3((28)^2/π)(25)

V=1/3(19,600/π)

V≈2,080cm^3

The volume of the Cam's hat measured in cubic centimetres is 2081 cm³

The volume of a cone is as follows:

where

h = height

r = radius

The circumference of the part of his head where the hat will rest is 56 cm. Let's find the radius

h = 25 cm

V =  1 /  3 × π × (28 / π )² × 25

V =  1 / 3 × π × 784 / π² × 25

V = 19600 / 3π

V = 19600 / 9.42

V = 2080.67940552

V ≈ 2081 cm³

Answer:

The zeros of the polynomial are x = 7 or x = -11/2

Step-by-step explanation:

The zeros of a polynomial refers to the solution of the polynomial.

6x^2 + 19x -77

6x^2-14x+ 33x -77

2x(x-7) + 11(x-7)

= (2x + 11)(x-7)

2x + 11 = 0

x-7 = 0

2x = -11

x = -11/2 = -5.5

and x-7 = 0

x = 7

So the zeros of the polynomial are x = 7 or x = -11/2

Answer:

0.75 gallons

Step-by-step explanation:

As the statement indicates that Latrell wants the bedroom ceiling to be 85% blue and 15% white and you know that he needs 4.25 gallons of blue which represents the 85%, you can use a rule of three to find the amount that represents the 15% to know the gallons of white that he needs:

4.25 gallons → 85%

          x         ←  15%

x= (4.25*15)/85

x=0.75

According to this, the answer is that if Latrell needs 4.25 gallons of blue, he needs 0.75 gallons of white.

Answer:

6.5 * 10 ^ -9

Step-by-step explanation:

0.0000000065

Scientific notation means a* 10 ^b

where a  is number between 1 and less than 10

Move the decimal  9 places to the right which means the power of 10 is negative since we moved the decimal to the right

6.5

The power of 10 is -9

6.5 * 10 ^ -9

Answer:

6.5 * 10^-9 metres.

Step-by-step explanation:

This is < 1 so the exponent is negative

We count the number of digits after the decimal point up to and including the first digit > 0.

This is 9 digits.

So the answer is 6.5 * 10^-9.

Answer: True

Step-by-step explanation: The angles given are the same AND the side given us the same. The triangle has been reflected, but the reflection is still congruent.

The two triangles given are congruent according to the ASA congruence rule.

Two triangles are congruent if two angles and the included side of one triangle are equal to two angles and the included side of the other triangle.

The given triangles are both right angled triangles.

The side 12 units is the included side between the angles 45° and 90° in both the triangles. This is the required condition for ASA congruence rule.

Hence we can say that the triangles are congruent according to the ASA congruence rule. The answer is A.True.
