Answer:

[tex]\boxed {\boxed {\sf A. \ 0.60 \ km}}[/tex]

Step-by-step explanation:

Distance (how far the submarine travelled) can be found by multiplying the speed by the time.

[tex]d=s*t[/tex]

The speed is 2.4 kilometers per hour.

The time is 0.25 hours.

[tex]s= 2.4 \ km/hr \\t= 0.25 \ hr[/tex]

Substitute the values into the formula.

[tex]d= 2.4 \ km/hr * 0.25 \ hr[/tex]

Multiply. Note that the hours (hr) will cancel each other out.

[tex]d= 0.6 \ km/hr *hr[/tex]

[tex]d= 0.6 \ km[/tex]

The submarine travelled 0.6 kilometers in 0.25 hours.

Answer:

(8,6) and (10,4)

Step-by-step explanation:

solutions to the system of inequalities are in the purple shaded area, coordinates not landing in the purple shaded area are incorrect. The purple shaded area represents solutions for both lines red and blue.

Incorrect answers:

(0,10) because it lands in the blue shaded area ( meaning its the solution for only line blue and not line red)

(5,12) because it lands in the red shaded area ( meaning its the solution for only line red and not line blue)

(12,5) in red only

(15,2) in red only

Answer:

Step-by-step explanation:

1/4a + 1/3a + 8 = 22

Collect like terms

1/4a + 1/3a = 22 - 8

Simplify

3a+4a/12 = 14

7/12a = 14

Divide both sides by 7/12

a = 14 ÷ 7/12

= 14 × 12/7

= 168/7

= 24

a = 24

Check:

1/4a + 1/3a + 8 = 22

1/4(24) + 1/3(24) + 8 = 22

24/4 + 24/3 + 8 = 22

6 + 8 + 8 = 22

22 = 22

Answer: 77.6%

Step-by-step explanation: By using the basic calculation of percentage strategy, it's 77.6%

Solution :

The null and alternative hypothesis is given by

[tex]$H_0: \mu = 11$[/tex]

[tex]$H_a: \mu \ne 11$[/tex]

Assume that the level of significance, α = 0.05

The t-test statistics is, t = 1.484

Degree of freedom :

df = n - 1

   = 14 - 1

   = 13

The P-value is given by

P-value = 2P (T>|t|)

            = 2P(T>|1.484|)

            = 2P(T>1.484)

            = 2(=T.DIST.RT(1.484,13))

            = 0.05

Step-by-step explanation:

Answer:

x = 15

y = 4

Step-by-step explanation:

In a triangle a line parallel to any of the sides of the triangle divides the remaining two sides in the proportion. Therefore,

[tex] \frac{12}{y} = \frac{x}{5} = \frac{18}{6} \\ \\ \frac{12}{y} = \frac{x}{5} = \frac{3}{1} \\ \\ \implies \:\frac{x}{5} = \frac{3}{1} \\ \\ x = 5 \times 3 \\ \\ x = 15 \\ \\ \\ \frac{12}{y} = \frac{3}{1} \\ \\ 3y = 12 \\ \\ y = \frac{12}{3} \\ \\ y = 4[/tex]

Answer:

G

Step-by-step explanation:

(x)0 months: (y)15 toys, 1:17, 2:19, 3:21, 4:23, 5:25, 6:27, 7:29, 8:31, etc.

The equation that represents best shows this relationship between the number of toys Rudolfo has will be y = 2x + 15. Then the correct option is G.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Rudolfo has 15 toys in his toy box, and he adds 2 new toys every month.

Let x be the number of months and y be the total number of toys. Then the equation is given as,

y = 2x + 15

The equation that represents best shows this relationship between the number of toys Rudolfo has will be y = 2x + 15. Then the correct option is G.

There are 168 cookies. 14 times a dozen (12) is 168.

The ratio of cups of sugar to cookies is 7.5 to 168.

If you want to find the cups of sugar you need for 168, divide 7.5 and 168 by 168.

168/168=1

7.5/168 is about 0.04.

The cups of sugar you use for one cookie is 0.04.

Answer:

I) The roots are:

First Case:

[tex]x=-2\text{ or } x=-6[/tex]

Second Case:

[tex]x=2\text{ or } x=6[/tex]

II) Possible values of p are:

First Case:

[tex]p=-12[/tex]

Second Case:

[tex]p=4[/tex]

Step-by-step explanation:

We have the equation:

[tex]x^2-(4+p)x+12=0[/tex]

We know that one of the roots is three times the other.

And we want to find the roots of the equation and the possible values for p.

To find our solutions, we can use the process of factoring.

If we have an equation in the form:

[tex]x^2+bx+c=0[/tex]

We want to find two numbers, say, k and j, such that:

[tex]\displaystytle kj=c\text{ and } k+j=b[/tex]

After finding them, we can factor as such:

[tex](x+k)(x+j)[/tex]

So, -k and -j will be our zeros.

Therefore, for our equation, we will find two numbers k and j such that:

[tex]\displaystyle kj=12\text{ and } k+j=-(4+p)[/tex]

Notice that for the first criterion, we can simply list all the factors of 12.

So, according to the first equation, possible values of k and j are:

1 and 12; 2 and 6; or 3 and 4.

Then, our roots will be -1 and -12; -2 and -6; or -3 and -4, respectively.

However, remember that one of our roots is three times the other.

Therefore, the only candidates that work will be the second option.

Hence, k and j are 2 and 6.

Therefore:

[tex]k=2\text{ and } j=6[/tex]

With this information, we can now determine p. Since:

[tex]k+j=-(4+p)[/tex]

Then it follows that:

[tex]\begin{aligned}(2)+(6)&=-(4+p)\\8&=-(4+p)\\-8&=4+p\\p&=-12\end{aligned}[/tex]

Hence, our equation is:

[tex]x^2-(4+-12)x+12=0[/tex]

Or, factored:

[tex]x^2+8x+12=0 \text{ or } (x+6)(x+2)=0[/tex]

So, our roots are x=-6 and x=-2 when p=-12.

However, we also need to consider the negative factors of 12.

Factors of 12 also include -2 and -6.

Hence, our k and j can also be k=-2 and j=-6.

Then, in this case, our p is :

[tex]\begin{aligned} (-2)+(-6)&=-(4+p)\\-8&=-(4+p)\\8&=4+p\\p&=4\end{aligned}[/tex]

Therefore, for our second case, k=-2 and j=-6. Then p=4. So, our equation is:

[tex]x^2-(4+4)x+12=0[/tex]

Or, factored:

[tex]x^2-8x+12\text{ or } (x-2)(x-6)=0[/tex]

Hence, when p=4, our roots are x=2 and x=6.
