Answer:

The cost is less than $1.30

Step-by-step explanation:

Let

y-----> the total cost of a mobile phone call

x----> the time in minutes

we know that

if time were x=5 minutes

the cost would be

y=0.30+0.20(5)=$1.30

but

the time is less than 5 minutes

therefore

the cost would be

y< $1.30

Answer:

The possible cost of a call if it is shorter than 5 minutes ranges between 30 cents and maximum 130 cents

Step-by-step explanation:

Define a function as

Y: Cost of a call in cents

X: Number of minutes of call

So using the statement we can find that

Y=30+20X

because the cost of the call has a fix cost of 30 cents plus 20 cents per minute used. If the calls is shorter than 5 minutes for x = 5

Y=30+20X = 30 + (20*5) = 30 + 100 = 130 which is the cost of a call of max 5 minutes

Because you pay a fixed cost of 30 even if you spend very little time. X= 0 then the possible cost of a call if it is shorter than 5 minutes ranges between 30 cents and maximum 130 cents

Answer:

D. 21/2

Step-by-step explanation:

We simply have to evaluate the first three terms based on the progression's formula:

t= 1,  the first term is 8, as we see:

[tex]8(\frac{1}{4})^{t-1} = 8(\frac{1}{4})^{1-1} = 8 * 1 = 8[/tex]

t=2, the second term is 2, as we see:

[tex]8(\frac{1}{4})^{t-1} = 8(\frac{1}{4})^{2-1} = 8 * \frac{1}{4} = 2[/tex]

t=3, the third term is 1/2, as we see:

[tex]8(\frac{1}{4})^{t-1} = 8(\frac{1}{4})^{3-1} = 8 * \frac{1}{16} = \frac{1}{2}[/tex]

The sum of the first 3 terms is then: 8 + 2 + 1/2 = 10 1/2

Among the answer choices, D. 21/2, which is 10 1/2.

Answer: [tex]A=100ft^2[/tex]

Step-by-step explanation:

You can use the following formula calculate the area of a rectangle:

[tex]A=w*h[/tex]

Where "w" is the width of the rectangle and "h" is the height of the rectangle.

In this case you know that this rectangle is 12.5 feet wide and  8 feet tall.  Therefore, you can substitute values into the formula to find its  area.

Then, you get that the area of this rectangle is the following:

[tex]A=(12.5ft)(8ft)\\\\A=100ft^2[/tex]

Answer:

1.) b/19

Step-by-step explanation:

a/b=12/19

you can always swap the b and the 12 (quick SAT trick)

To find the ratio that completes the equivalent proportion for a/12 using the given proportion a/b = 12/19, you will need to use cross multiplication.
Let's denote x as the unknown value that we are trying to find such that a/12 = b/x. To solve for x, we set up the proportion like this:
a/12 = b/x
Now let's cross multiply:
a * x = 12 * b
Since we know from the initial proportion that a/b = 12/19, we can substitute 12/19 for a/b in the equation:
(12/19) * b * x = 12 * b
Now we have b on both sides of the equation, and assuming b is not equal to zero, we can divide both sides of the equation by b to solve for x:
(12/19) * b * x / b = 12 * b / b
12/19 * x = 12
Now we need to isolate x:
x = 12 / (12/19)
To simplify this, you can multiply 12 by the reciprocal of 12/19, which is 19/12:
x = 12 * (19/12)
The 12s cancel each other out:
x = 19
Therefore, the ratio that completes the equivalent proportion is b/19.
The correct answer is:
1.) b/19

Answer:

12-6u

Step-by-step explanation:

To remove the parenthesis, we must multiply the number on the outside to each value within the parenthesis

This means that

[tex]6(2-u)\\\\6*2-6*u\\\\12-6u[/tex]

The distributive property is used to remove parentheses by multiplying each term within the parentheses by the number outside. Thus, the expression 6(2 - u) becomes 12 - 6u.

The distributive property is a mathematical principle that shows how to expand an expression involving brackets (or parentheses). To use the distributive property to remove the parentheses in the expression, you multiply the number outside the parentheses by each term inside the parentheses individually. Let's apply this to the expression you provided, 6(2 - u).

First, multiply 6 by 2. This results in 12. Next, multiply 6 by -u. This gives -6u. Therefore, the expression 6(2 - u) without parentheses, using the distributive property, is 12 - 6u.

Answer:

The measure of angles of △SPT are

∠PTS=35°, ∠PST=19°, ∠SPT=126°

Step-by-step explanation:

Given the figure in which

m∠EPT=54° and arc TP=70°

we have to find angles of △SPT

By tangent chord angle theorem, which states that the angle make by a tangent to a circle and a chord is equals to half of the angle measure of the intercepted arc i.e

[tex]\angle PTS=\frac{1}{2}\angle POT[/tex]

[tex]\angle PTS=\frac{1}{2}\times 70^{\circ}=35^{\circ}[/tex]

As ∠EPT and ∠SPT form linear pair therefore their sum equals to 180°

⇒ ∠EPT+∠SPT=180°

54°+∠SPT=180°

∠SPT=126°

In △SPT, by angle sum property of triangle

∠PST+∠SPT+∠PTS=180°

∠PST+126°+35°=180°

Second option: multiply input number by 4.

Step-by-step explanation:

You need to remember that the "input numbers" are the values of "x" and the "output numbers" are the values of "y".

You can observe in the table that each output number is always four time its corresponding input number. This means that to find the missing numbers on the given table, you need to multiply the corresponding input number by 4.

Therefore, you get:

For [tex]x=3[/tex] :

[tex]y=4x\\y=(4)(3)\\y=12[/tex]

For [tex]x=6[/tex] :

[tex]y=4x\\y=(4)(6)\\y=24[/tex]

To find the missing numbers in the table, square the input for the first missing number, and multiply the input by 4 for the second missing number. The missing numbers are 9 and 24.

To find the missing numbers in the table, you can follow the pattern provided in the instructions:

1. Multiply the input number by itself to get the output number.

2. Multiply the input number by 4 to get the second output number.

Let's calculate the missing numbers using this pattern:

For the first missing number:

Input: 3

Output: 3 * 3 = 9

For the second missing number:

Input: 6

Output: 6 * 4 = 24
