This is a simple ratio problem.

Jordyn swims 4/5 mile in 1/3rd hour. So how many miles will they go in 1 hour? Let that be x:

That is 12/5 miles or 2  2/5 miles

In decimal, that's 2.4 miles

Answer:

76.1

Step-by-step explanation:

y = ice cream

z = Tempreature

y = 1.8(85) - 76.9

1.8(85) = 153

153 - 76.9 = 76.1

Answer:

76

Step-by-step explanation:

y = 1.8(85) - 76.9

y = 153 - 76.9

y = 76.1

and when you round to the nearest whole number,

y = 76

Answer:

The correct option is;

C. 4800 J

Step-by-step explanation:

The given parameters are;

The mass of the skier = 40 kg

The height of the slope = 12 meter

The acceleration due to gravity, g = 10 m/s²

The potential energy, PE, is given by the formula PE = Mass, m × Acceleration due to gravity, g × Height, h

Substituting the values, gives

The potential energy, PE = 40 kg × 10 m/s² × 12 m = 4800 kg·m²/s² = 4800 J

The potential energy, PE = 4800 J

LCM(84,90) = 1260

Answer:

HCF = 2 * 3

LCM = 2 *2 * 3 * 3 * 5 * 7

Step-by-step explanation:

A) 84 = 2 * 2  * 3 * 7

   90 =  2 * 3 * 3 * 5

HCF = 2 * 3

B) 84 = 2 * 2 * 3 *7

   90 = 2 * 3 * 3 * 5

LCM = 2 *2 * 3 * 3 * 5 * 7

Answer: $9.20

Step-by-step explanation: To get the answer, you add both the cost and multiply it by .15. Then you add the product to the number you got adding the cost of the food.

Answer:

$1.20

Step-by-step explanation:

He has to leave 100% of the cost which is $5.50 + 2.50 or $8.00.

He wants to leave 115% of the $8 he has to leave.

So you set it up like

x/8 = 115/100

Then you solve for x

8(115) = 920

920/100 =9.2

So he will leave $9.20.

It then asks for just how much the tip is that he will leave so

9.2 - 8 = 1.2

So the tip is $1.20.

Answer:

y=5x+14

Step-by-step explanation:

Answer:

Check the explanation.

Step-by-step explanation:

As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.

As the slop-intercept form is given by:

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept.

substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.

[tex]y = mx+b[/tex]

[tex]-10=\frac{5}{2}\left(-2\right)+b[/tex]

[tex]-\frac{5}{2}\cdot \:2+b=-10[/tex]

[tex]-5+b=-10[/tex]

[tex]-5+b+5=-10+5[/tex]

[tex]b=-5[/tex]

And the equation of the line in the slope-intercept form will be:

[tex]y = mx+b[/tex]

putting b = -5 and slope = m = 5/2

[tex]y = mx+b[/tex]

[tex]y=\frac{5}{2}x+\left(-5\right)[/tex]

[tex]y=\frac{5}{2}x-5[/tex]

Determining the zero of function.

As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.

so let us determine the value of x (zero of function) by setting y = 0.

[tex]0=\frac{5}{2}x-5[/tex]

[tex]\frac{5}{2}x-5=0[/tex]

[tex]\frac{5}{2}x=5[/tex]

[tex]5x=10[/tex]

[tex]x=2[/tex]

Therefore, the zeros of the function will be:

Answer:

a = -40/3

Step-by-step explanation:

(7a - 4) = (4a - 44)

7a - 4 = 4a - 44

7a = 4a - 44 + 4

7a = 4a - 40

7a - 4a = - 40

3a = - 40

3a/3 = -40/3

a = -40/3 or -13.3333 repeating

Answer:

30

Step-by-step explanation:

Prime factors of 90 = 2 x 3^2 x 5

Prime factors of 120 = 2^3 x 3 x 5

Prime factors of 150 = 2 x 3 x 5^2

Common prime factors with lowest exponent: 2, 3, 5

HCF(highest common factor) = 2 x 3 x 5 = 30

Answer:

30

Step-by-step explanation:

30 is divisible by 90, 120 and 150

Answer:

x = 18

Step-by-step explanation:

2x + 3(4) - 1 = 47

Begin by combining your like terms

2x + 12 - 1 = 47

2x + 11 = 47

Isolate your variable (x) by using inverse operations

2x = 36

x = 18

Answer: 41 units

Step-by-step explanation: took the quiz

The length of the diagonal is 41 units.

To find the length of a diagonal.

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees.

Let a right triangle with legs length 9 units and 40 units and hypotenuse is the diagonal length c.

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]9^{2} +40^{2} =c^{2}[/tex]

[tex]81+1600=c^2\\1681=c^2[/tex]

sqrt both sides

41=c

So, the length of the diagonal is 41 units.

the number 3 is rational because it is an integer

Answer:

94

Step-by-step explanation:

Let the unit's digit = [tex]y[/tex]

Let the ten's digit = [tex]x[/tex]

Then the number will be equal to [tex]10x+y[/tex]

Now, using the given statement:

[tex]x=y+5 ..... (1)[/tex]

[tex]7(x+y) = 10x+y-3\\\Rightarrow 7x+7y=10x+y-3\\\Rightarrow 6y-3x=-3 ..... (2)[/tex]

Now, using the equation (1) in equation (2):

[tex]6y-3(y+5) =-3\\\Rightarrow 3y-12=0\\\Rightarrow y =4[/tex]

By equation (1):

[tex]x = 4+5 \\\Rightarrow x =9[/tex]

Therefore, the number is :

[tex]10x+y= 10\times 9 +4 = \bold{94}[/tex]
