Answer:

It took Peter 28 minutes and 10.82 seconds to finish the race.

Step-by-step explanation:

We have that:

[tex]t_{A}[/tex]: Antonio = 28 min + 11.00 s (1)

[tex]t_{J}[/tex]: Julio = A - 0.08 s  (2)

[tex]t_{P}[/tex]: Pete = J - 0.1 s   (3)

Then, the time at which Pete finished the race is:

[tex] t_{P} = t_{J} - 0.1 [/tex]   (4)

By entering equations (1), (2), (3) into (4) we have:

[tex] t_{P} = (t_{A} - 0.08) - 0.1 [/tex]            

[tex] t_{P} = 28 min + 11.00 s - 0.18 s = 28 min + 10.82 s [/tex]

Therefore, it took Peter 28 minutes and 10.82 seconds to finish the race.    

I hope it helps you!

Step-by-step explanation:

Since, K is the midpoint of JL.

[tex] \therefore \: JK = KL \\ 8x + 11 = 14x - 1 \\ 11 + 1 = 14x - 8x \\ 12 = 6x \\ \frac{12}{6} = x \\ 2 = x \\ \\ \because \: JL = JK + KL \\ \therefore \: JL = 8x + 11 + 14x - 1 \\ \therefore \: JL = 8x + 14x + 11 - 1 \\ \therefore \: JL = 22x + 10\\ \therefore \: JL = 22 \times 2 + 10..(plug \: x = 2) \\ \therefore \:JL = 44 + 10 \\ \huge \red{ \boxed{\therefore \:JL = 54}}[/tex]

Step-by-step explanation:

5(4 + 8) =

Distribute

5*4 + 5*8

20 + 40

60

Answer:

60

Step-by-step explanation:

We want to complete the expression using the distributive property. The expression is:

5(4+8)

Distribute first. Multiply each number inside the parentheses by the number outside the parentheses, which is 5.

(5*4)+(5*8)

Multiply 5 and 4.

20+(5*8)

Multiply 5 and 8.

20+40

Add 20 and 40.

60

The expression 5(4+8) is equal to 60.

Answer:

$4.25

Step-by-step explanation:

4 quarters is 1 dollar

1 nickel is 5 cent

14 divided by 4 = 3.5

3.5 + 5 times 5 =  $4.25

Step-by-step explanation:

1 dollar = 4 quarters

1 dollar = 20 nickel

1 nickel = 0.2 quarter

5 nickel = 0.2 x 5 = 1 quarter

14+ 1 = 15 quarter

15 quarter = 3.75$

Answer:

this how I got the answer

Step-by-step explanation:

find the angle A ..B

it's a straight line so 180.

180_148=32

In angle C..it's a full turn.so 360

360_290=70

we just have to find one more angle...

it's a straight line ..so as we know 180

32+70=102

180_102=78

Answer:

When factorizing one number, what you get are other numbers that, when they get multiplied, the result of the product is the first number.

In our case, the pair of 3, 12 and the pair of 4, 9 are factors of 36, as it's the number we get when multiplying them:

We can factroize 36 like this: 2*2*3*3, and:

The factor pairs belong to the number 36.

The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.

As per the given data:

The factor pairs are as follows:

3, 12

4, 9

We have to find out that of which number these factor pair belongs.

When the factors of any number are multiplied with each other, we get that number.

For finding out the number, we need to multiply the factor pairs:

3 × 12 = 36

4 × 9 = 36

The factor pairs belong to the number 36.

Hence, The factor pairs belong to the number 36.

Answer:

[tex]f(x)=2x+3[/tex]

Step-by-step explanation:

So we know that:

[tex]f(1)=5 \text{ and } f(3)=9[/tex]

In other words, we have 2 coordinates: (1,5) and (3,9).

With this, we can figure out the slope. Let (1,5) be x₁ and y₁ and let (3,9) be x₂ and y₂. The slope formula is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute:

[tex]m=\frac{9-5}{3-1}\\m=4/2=2[/tex]

So, the slope is 2.

Now, use the point-slope form to figure out the y-intercept. The point-slope form is:

[tex]y-y_1=m(x-x_1)[/tex]

For consistency, let's continue to use (1,5) as x₁ and y₁. Now, we can use 2 as m. Thus:

[tex]y-(5)=2(x-1)[/tex]

Distribute:

[tex]y-5=2x-2[/tex]

Add 5 to both sides:

[tex]y=2x+3[/tex]

So:

[tex]f(x)=2x+3[/tex]

And that's our equation :)

Step-by-step explanation:

Sharonda is plotting quadrilateral PQRS on the graph below She will plot the fourth and final vertex, S, at (9, 5), the length of side PS will be 11 units.

A quadrilateral is a four-sided polygon. The sum of the interior angles of a quadrilateral is always equal to 360 degrees. There are several types of quadrilaterals, including: Square, rectangle, parallelogram, rhombus, trapezoid, and kite.

Length of side PS can be calculated using the distance formula,

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Where,

P(-2, 5) = ([tex]x_1,y_1[/tex]) (the coordinate of P is gotten from the graph).

Given that,

S(9, 5) = ([tex]x_2,y_2[/tex])

PS = [tex]\sqrt{(9-(-2))^2+(5-5)^2}[/tex]

PS = [tex]\sqrt{11^2+0^2}[/tex]

PS = [tex]\sqrt{121}[/tex]

PS = 11units.

Thus, the answer is 11 units.

Answer:

x = -2

y = -4

Step-by-step explanation:

Graph the systems of equations. Then analyze the graph for the intersection. The point of intersection will be your solution set.

Answer:

[tex]x = -2\\y = -4[/tex]

Step-by-step explanation:

Question

[tex]\left \{ {{-2x + 2y = -4} \atop {3x + 3y = -18}} \right.[/tex]

Multiply throughout the equation to eliminate a variable:

[tex]-2x + 2y = -4[/tex] becomes [tex]-6x + 6y = -12[/tex] when multiplied by 3

[tex]3x + 3y = -18[/tex] becomes [tex]6x + 6y = -36[/tex] when multiplied by 2

Then add the values of the variables together:

[tex]-6x + 6x = 0\\6y + 6y = 12y \\-12 - 36 = -48[/tex]

And a new equation forms:

[tex]0 + 12y = -48[/tex]

[tex]y = -4[/tex]

Plug in [tex]y[/tex] to any of the previous equations to solve for [tex]x[/tex] :

[tex]-2x + 2y = -4[/tex]

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

[tex]-2x - 8 = -4[/tex]

[tex]-2x = 4[/tex]

[tex]x = -2[/tex]

Answer:

This is done by stating descriptions of these terms.

Step-by-step explanation:

Undefinable terms are terms with no formal definitions. Formal definitions are obtained when specific words are used to define a term. In mathematics, specifically, Geometry words like line, point, and plane have no definite definition, So descriptions are used to identify them.

For example, in describing a point, we note that a point has no dimensions, it is usually denoted with a capital letter, and it indicates a position. Also in a coordinate plane, it is denoted with descriptions such as  (u,v). Corresponding descriptions are given of other undefinable terms.

Answer: Badwater is 282 feet below the sea level.

Step-by-step explanation:

Given: Death Valley headquarters in California is 190 feet below sea level. Badwater, America's lowest point, is 92 feet lower than Death Valley headquarters.

To find the depth of Badwater we need to add depth of Death Valley headquarters from sea level to the depth of Badwater from Death valley headquarters.

i.e. The Depth of Badwater from sea-level = 190 feet +92 feet

= 282 feet

Hence, Badwater is 282 feet below the sea level.

Answer:

282

Step-by-step explanation:

190+(92)=282

Answer:

6682

Step-by-step explanation:

So we have a 4 digit number and we need to find all the digits of it.

First, we are told that the one digit is 2. So the number is xxx2

Now, we know that the tens digit is 4 times greater than the ones, thus, the tens digits is 4 times 2, this is 4(2) = 8. Thus, the tens digit is 8 and the number is xx82.

Finally we know that the hundreds and thousands are both 3 times greater than the ones, so the digits are 3(2) = 6. Thus the hundreds and thousands are 6 and the final number is 6682.
