lena purchased a prepaid phone card for $20. long distance call cost 18 cents a minute using this card. Lena used her cared only once to make a libg distance call. if the remaining credit on her card is $13.34, how many minutes did her call last?
Answer:
37 minutes
Step-by-step explanation:
We start by finding the difference between the original amount and what is left
Mathematically, that will be;
20-13.34 = 6.66
To
cents that will be 6.66 * 100 = 666 cents
We now divide by the amount per minute
The amount per minute is 18 cents
Thus, the number of minutes will
be 666/18 = 37

The slope of the line that passes through the points
(3, 14) and (7, 9) is
ASAP
Answer:
[tex]\boxed {\boxed {\sf m= - \frac{5}{4} }}[/tex]
Step-by-step explanation:
The formula for slope is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are the points the line passes through.
The line passes through (3,14) and (7,9). Therefore,
[tex]x_1=3 \\y_1=14 \\x_2=7 \\y_2=9[/tex]
Substitute the values into the formula.
[tex]m= \frac{9-14}{7-3}[/tex]
Solve the numerator.
[tex]m=\frac{-5}{7-3}[/tex]
Solve the denominator.
[tex]m= \frac{-5}{4}[/tex]
This fraction is reduced, so it is the answer.
The slope is equal to -5/4

Given:
The canvas has 2 pairs of parallel sides and 4 right angles.
The sides are not all of equal length.
To find:
The shape of the canvas.
Solution:
Rectangle: A rectangle is a quadrilateral whose opposite sides are parallel and equal. All the interior angles of a rectangle are right angles.
Note: All sides of a rectangle are not equal. If they are equal then it is known as square.
It is given that the canvas has 2 pairs of parallel sides and 4 right angles. The sides are not all of equal length.
Therefore, the shape of the canvas is a rectangle.

1 The length of a rectangle is 10 inches, and the
width is represented by 3x. Which best
represents an equation and solution for x if the
area of the rectangle is 40 square inches?
A 10(3x) = 40; X = 4
B 30x = 40; x = 1;
C 3x = 40; x = 13
D 3x + 10 = 40; X = 10
Answer:
A
Step-by-step explanation:
To find the area of a rectangle, it is length times width (10*3x), and if it equals 40, you could just write that after the equation, and then find out that "x" would equal [tex]\frac{4}{3}[/tex]
Answer:
30x = 40 ; x ≈ 1
Step-by-step explanation:
[tex]A^{}[/tex] = [tex]l^{}[/tex] [tex]w^{}[/tex]
[tex]l^{}[/tex] = 10 inch.
[tex]w^{}[/tex] = 3x
10(3x) = 40
30x = 40 ; x = [tex]1\frac{1}{3}[/tex] ≈ 1

Find the perimeter of rectangle LINT.
Answer:
[tex]P = 22.75[/tex]
Step-by-step explanation:
Given:
See attachment for rectangle LINT
Required
Calculate its perimeter
From the attachment:
Considering triangle LYT, we apply Pythagoras theorem.
[tex]LT^2 = LY^2 + TY^2[/tex]
Where:
[tex]LY = 5.2[/tex]
[tex]TY = 3.9[/tex]
The formula becomes:
[tex]LT^2 = 5.2^2 + 3.9^2[/tex]
[tex]LT^2 = 42.25[/tex]
Take positive square root of both sides
[tex]LT = \sqrt{42.25[/tex]
[tex]LT = 6.5[/tex]
Next, we calculate the length of NT.
By comparing triangles LYT and NYT
We make use of the following equivalent ratios to solve for NT
[tex]NT:TY = LT:LY[/tex]
[tex]NT : 3.9 = 6.5 : 5.2[/tex]
Convert to fractions
[tex]\frac{NT}{3.9} = \frac{6.5}{5.2}[/tex]
Make NT, the subject:
[tex]NT = \frac{6.5}{5.2}*3.9[/tex]
[tex]NT = \frac{6.5*3.9}{5.2}[/tex]
[tex]NT = \frac{25.35}{5.2}[/tex]
[tex]NT = 4.875[/tex]
The perimeter (P) is then calculated as:
[tex]P = NT + LT + LI + NI[/tex]
Where
[tex]NT = LI[/tex] and [tex]LT = NI[/tex] -- opposite sides of rectangle.
So:
[tex]P = NT + NT + LT + LT[/tex]
[tex]P = 2NT + 2LT[/tex]
Substitute values for NT and LT
[tex]P = 2*4.875 + 2*6.5[/tex]
[tex]P = 9.75 + 13.0[/tex]
[tex]P = 22.75[/tex]
Hence, the perimeter is 22.75 units
After a price increase of 20% the cost of entry to a museum rose to $25.80.
Find the original price.
-------------------------------------------- Please help and explain how to do this equation. Tia
Answer:
$20.64
Step-by-step explanation:
0.20x25.80=5.16
25.80-5.16=20.64
The original price to get entry to a museum is $20.64 .
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let call 'a' be the original price.
if it rose of 20 % , it's mean that it will multiplicate by 0.20
0.20 x 25.80=5.16
a = 25.80 - 5.16=20.64

An engineer is using computer-aided design (CAD) software to design a component for a space shuttle. The scale of the drawing is 1 cm : 60 in. The actual length of the component is 12.75 feet. What is the length of the component in the drawing?
============================================================
Work Shown
1 foot = 12 inches
12.75 ft = 12.75*12 inches = 153 inches
The scale of 1 cm : 60 in allows us to form the proportion below
(1 cm)/(60 in) = (x cm)/(153 in)
1/60 = x/153
1*153 = 60*x ..... cross multiply
153 = 60x
60x = 153
x = 153/60
x = 2.55
The length of the component in the drawing is 2.55 cm
Side note: This is equivalent to 25.5 mm since 1 cm = 10 mm (ie you multiply by 10 to go from cm to mm).
