Donna is going to swim 19 laps. She completed 12 laps what fraction of her swim remains?

Answers

Answer 1

Answer:

7/19 laps

Step-by-step explanation:

She has 19 total laps to do so you know that the denominator is 19.

She already completed 12 laps so that means she has 7 laps left out of the 19 total laps because 19-12= 7

The cost of each 1 pound candy is $30, 1 box of cookies is $5 and 1 can of popcorn is $10.

We have the church youth group is selling snacks to raise money to attend their convention.

We have to determine the cost of each item they sold.

Write the following statement in the form of a mathematical equation - Steve bought 2 toffees each of $x and 5 chocolates each of $y. The total cost is $50.

The mathematical equation representing the above statement is -

2x + 5y = 50

According to question -

Assume that the cost of :

1 pound candy = $x

1 box of cookies = $y

1 can of popcorn = $z

Now, write down the mathematical equation representing their total sales -

Amy -      2x + 3y + z = 85

Brian -     4x + 4y + 3z = 170

Paulina -     8x + 8y + 5z = 330

We will use the Cramer's rule to solve these equations -

The 3 x 3 coefficient matrix is -

[tex]\left[\begin{array}{ccc}2&3&1\\4&4&3\\8&8&5\end{array}\right][/tex]

Find its determinant -

D = 2(4 x 5 - 3 x 8) - 3(4 x 5 - 8 x 3) + 1(4 x 8 - 4 x 8) = 4

Create the X- matrix (X - matrix is formed by replacing the x-column values with the answer-column values) as follows -

[tex]\left[\begin{array}{ccc}85&3&1\\170&4&3\\330&8&5\end{array}\right][/tex]

Find th determinant of this X - matrix same as done above -

D(X) = 120

Similarly create a Y - matrix and Z - matrix and find their respective determinants. On solving you will get -

D(Y) = 20

D(Z) = 40

According to the Cramer's rule -

[tex]$x = \frac{D_{x} }{D}[/tex]

[tex]$y = \frac{D_{y} }{D}[/tex]

[tex]$z = \frac{D_{z} }{D}[/tex]

Therefore -

x = 120/4 = 30

y = 20/4 = 5

z = 40/4 = 10

Hence, the cost of each 1 pound candy is $30, 1 box of cookies is $5 and 1 can of popcorn is $10.

If tan t= 2/3 then cos t =3
True or false?

Answers

Answer:

FALSE

Step-by-step explanation:

We are assuming that t is a real number.

Thus, cos(t) is a real number greater than or equal to -1 and less than or equal to +1.  

Thus, cos(t) = 3 is false for all real t, and so in particular it is false for the value(s) of t such that tan(t) = 2/3.

The number line shows the graph of an inequality:

A number line is shown from negative 5 to positive 5 with increments of 0.5. All the whole numbers are labeled on the number line. An empty circle is shown on the first mark to the left of 0. The region to the left of the empty circle is shaded.

Which statement explains whether −1.5 can be a value in the shaded region?

Yes it can, because −1.5 lies to the left of −0.5
Yes it can, because −1.5 lies to the right of −0.5
No it cannot, because −1.5 lies to the left of −0.5
No it cannot, because −1.5 lies to the right of −0.5

Answers

Answer: Option A.

Step-by-step explanation: Draw a number line from negative 5 to positive 5 with increments of 0.5. Make an empty circle on the first mark to the left of 0. It means mark an open circle at -0.5.

The region to the left of the empty circle is shaded. It means all the points lie on the left side of -0.5 at in the shaded region.

We need to find a statement that explains whether −1.5 can be a value in the shaded region.

Since −1.5 lies to the left of −0.5 , therefore -1.5 is in the shaded region.

Therefore, the correct option is A.
