Answer:

AC ≈ 23.6 units

Step-by-step explanation:

m∠CAD = 90°

CD = 2×14 = 28 , AD = 15

CD² = AD² + AC² ⇒ AC² = CD² - AD²

AC² = 28² - 15² = ( 28 - 15 )( 28 + 15 ) = 13 × 43 = 559

AC ≈ 23.6

Answer:

y = 4

Step-by-Step explanation:

4x5 = 20

2x5 = 10

20+10=30.

(4x5) + (2x5) = 30

or

(yx5) + (2x5) = 30

Answer:

starting with least...

-1.6

-6/5

-7/8

9/10

5/2

...to greatest.

Step-by-step explanation:

start by putting the decimals into fractions:

-1.6 = -8/5

0.9 = 9/10

and then find a common denominator to compare them fairly.

the number that they all end up going into is 40, which will be your common demoninator.

-8/5 (aka -1.6) = -64/40

5/2 = 100/40

-7/8 = -35/40

9/10 (aka 0.9) = 36/40

-6/5 = -48/40

Answer:

The answer should be 5:12.

Step-by-step explanation:

Since the question asks what's the ratio of cheerleaders to football players, the ratio before simplifying would be 20:48.

So, just find the greatest common divisor of 20 and 48, which would be 4.

20/4 = 5

48/4 = 12

Therefore, the answer to this question and the ratio of cheerleaders to football players is 5:12.

Answer:

x = 5

Step-by-step explanation:

x + 4 = 3(x - 2) ← distribute parenthesis by 3

x + 4 = 3x - 6 ( subtract 3x from both sides )

- 2x + 4 = - 6 ( subtract 4 from both sides )

- 2x = - 10 ( divide both sides by - 2 )

x = 5

Answer:

Step-by-step explanation:

In the question we have given an equation that is x + 4 = 3 ( x - 2 ) . And we are asked to solve the question that means we have to find the value of x .

Solution : -

[tex] \longrightarrow \quad \: x + 4 = 3(x - 2)[/tex]

Step 1 : Solving parenthesis on right side :

[tex] \longrightarrow \quad \: x + 4 = 3x - 6[/tex]

Step 2 : Subtracting 4 on both sides :

[tex] \longrightarrow \quad \: x + \cancel{4} - \cancel{ 4 }= 3x - 6 - 4[/tex]

On further calculations we get :

[tex] \longrightarrow \quad \: x = 3x - 10[/tex]

Step 3 : Subtracting 3x on both sides :

[tex] \longrightarrow \quad \: x - 3x = \cancel{3x } - \cancel{3x}- 10[/tex]

On further calculations we get :

[tex]\longrightarrow \quad \: - 2x = - 10[/tex]

Step 4 : Dividing both sides by -2 :

[tex]\longrightarrow \quad \: \dfrac{ \cancel{ - 2}x}{ \cancel{ - 2} } = \cancel{\dfrac{ - 10}{ - 2} }[/tex]

On further calculations we get :

[tex]\longrightarrow \quad \: \red{\underline\red{\boxed{ \frak{ x = 5}}}}[/tex]

Verifying : -

We are verifying our answer by substituting value of x in given equation. So ,

Therefore, our answer is correct .

Answer: [tex]-\frac{7}{11}[/tex]

Step-by-step explanation:

The formula for finding slope is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Where [tex](x_{1} ,y_{1} )[/tex] are the coordinates of the first point and [tex](x_{2} ,y_{2} )[/tex] are the coordinates of the second point.

Sub the values in

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\\\frac{5-(-2)}{-5-6} \\[/tex]

Now solve

[tex]\frac{5-(-2)}{-5-6} \\\frac{7}{-11}[/tex]

Slope:-

[tex]\\ \rm\dashrightarrow m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \rm\dashrightarrow m=\dfrac{5+2}{-5-6}[/tex]

[tex]\\ \rm\dashrightarrow m=\dfrac{-7}{11}[/tex]

Answer:

252

Step-by-step explanation:

The least common multiple is the product of all factors in the greatest number of their occurrence.

LCM = 2 x 2 x 3 x 3 x 7

LCM = 2^2 x 3^2 x 7

LCM = 252

The least common multiple of 28, 42 and 63 is 252.

Answer:

LCM = 252.

Step-by-step explanation:

First find their prime factors:

28 = 2*2*7

42 = 2*3*7

63 = 3*3*7

So, only including like factors once, LCM =

2*2*3*3*7

= 252

Answer:

I'm pretty sure y is the height.

Answer:

y = 110 degree

x = 70 degree

z = 70 degree

Step-by-step explanation:

Vertical angles are always congruent.

so, the angle with the 110 degree is equal to the angle y.

now we have the measure of y.

as you can see angle y and angle z form a straight light wich means the sum of angle y and angle x is 180 degree

now, to get the measure of angle z,

180 - 110 = angle z

70 = angle z

now we have the measure of angle z

as angle z and angle x are vertical angle, they are congruent.

so angle x = 70

x = 70

z= 70

y = 110

Answer:

91,300 to 3 s.f.

Step-by-step explanation:

The population is reduced by a percentage 100-7 = 93%  ( or 0.93) per year.

So after 5 years thatwould be 300,000(0.93)^5

= 208707

that is 300,000 - 208,706

= 91293

= 91,300 to 3 s.f.

Answer:

Step-by-step explanation:

This quadratic equation is given in standard form, which is [tex]y= ax^2 +bx+c[/tex]. The x-value of the vertex of a quadratic equation can be found using the given formula. Therefore, we can plug the the numbers given into the formula as such: [tex]x=\frac{24}{2(6)}[/tex]. This can be simplified into 2. Now that we have the x-coordinate, we can plug that back into the equation to find the y-coordinate: [tex]y=6(2)^2-24(2)+30[/tex]. This simplifies to y = 6. Therefore, the vertex of the equation is located at (2,6).

Hope this helps!
