Fernando had to pay $1.40 in sales tax when he purchased a shirt . If the sales tax rate is 7% how much did his shirt cost
Answer:
$20
Step-by-step explanation:
Work backwards so Price(.07) = $1.40 so x (.07) = 1.40, solving for x then
x = 1.4/.07 so x = 20
The cost of the shirt of Fernando is $20.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Fernando had to pay $1.40 in sales tax when he purchased a shirt . The sales tax rate is 7%.
The cost of the shirt is calculated as,
$1.40 = x (.07)
x = 1.4/.07
x = $20
Therefore, the cost of the shirt of Fernando is $20.

Answer:
Step-by-step explanation:
METHOD 1
in centre it is split by 4, each angle is equal.
in a square angles add up to 360°
360/4=90°
∴∠DOC=90°
if you have to do more work or have toexplain more, or you dont get that way there is another method:
METHOD 2
since ABCD is a square it alladds up to 360°
so ∠A=B=C=D=90°
in triangle DOC anles add up to 180°
each diagonal cuts angleA,B,C and D in half
so in triangle DOC, ∠ODC=∠CDO=45
∠DOC=180-∠DOC-∠CDO (or 180-(∠DOC+∠CDO)
∠DOC=180-45-45
∠DOC=90

Answer: b = 7.4 yards
Step-by-step explanation:
In a right angle triangle, the length of each base squared added together is equal to the hypotenuse squared (Pythagorean theorem written as a^2 + b^2 = c^2)
The bases are b and 3 and the hypotenuse is 8
b^2 + 3^2 = 8^2
b^2 + 9 = 64
b^2 = 55
the square root of 55 is approximately 7.4

How many times would you expect to get
the following cards:
(a) A red card?
(b) A King?
(C) The Queen of hearts?
Step-by-step explanation:
a ). red cards = 26
then probability is = no. of outcomes / total no. of outcome
p ( red card ) = 26 / 1040
p ( red card ) = 1 / 40
b ) kings = 4
p ( kings ) = 4 / 1040
p ( kings ) = 1 / 260
c ) queen of hearts = 1
p ( queen of heart ) = 1 / 1040

If gdp is $20 trillion how many years will it take for a gdp to increase to 80$ trillion if growth is 7 percent
Answer:
19. 8 years
Step-by-step explanation:
Using the exponential growth function :
A = Pe^rt
A = final amount or growth unit
P = initial or present growth unit
Rate, r = growth rate
80 = 20e^0.07t
80/20 = e^0.07t
4 = e^0.07t
Take In of both sides
In(4) = 0.07t
1.3862943 = 0.07t
t = 19.804205
t = 19. 8 years
David Smith and his 2 children are going to a zoo.The admission price is:
Adult: £60
Child: £45
David has a family discount card.
Family Discount Card gives
1/4
off adult price
40% off child price
Work out the total price David pays after using his discount card
Answer:
£101
Step-by-step explanation:
60 divided by 4 = 15
15 x 3 = 45
£45 = adult price
10% of £45 = £4.50
40% of £45 = £18
£45 - £18 = £27
£27 = 1 child ticket
£27 x 2 = £56
£56 = two child tickets
£56 + £45 = £101

Marisa’s mother is driving her to a doctor’s appointment in a town 75 mi. away. If they travel at a constant rate of speed of 50 mph, how long will it take to get to the doctor’s office? A. 1 hr. B. 1.5 hr. C. 2.5 hr. D. 3 hr.
Answer:
B) 1.5 hr
Step-by-step explanation:
75 miles/50 mph = 1.5 hrs
Answer:
B.1.5
Step-by-step explanation: We can already add 1 hour to the answer since 75 minus 50 would be 25. Next, we know that 25 is one half of 50 so that would result in us adding half an hour or 0.5. Now we can add. 1 plus 0.5 results in 1.5

Select the statement(s) that accurately describes the nature of an angle in standard position. (Select all that apply.) A)Two or more positive angles can not share the same terminal side. B)An obtuse angle is any angle whose terminal side is not in quadrant 1. C)An acute angle can have its terminal side in quadrant 4. D)Its vertex is at the origin. E)The terminal side of a negative-measured angle is generated in the clock-wise direction from the x-axis.
Answer:
Step-by-step explanation:
D) Its vertex is at the origin
E) The terminal side of a negative-measured angle is generated in the clock-wise direction from the x-axis.
The amount of rotation between the two rays forming the angle is known as the measure of the angle
The correct options are;
The options that gives the statements that accurately describes the nature of an angle in the standard position are;
D) Its vertex is at the origin.
E) The terminal side of a negative measured angle is generated in the clock-wise direction from the x-axis
Reason:
An angle is in the standard position where the location of the angle is at the origin, the positive direction is the counterclockwise, while the negative direction is the clockwise direction
The x-axis oriented ray is known as the initial side, while the other ray forming the angle is known as the terminal side
Therefore, the correct options are;
D. Its vertex is at the origin.
E. The terminal side of a negative measured angle is generated in the clock-wise direction from the x-axis

Answer:
Step-by-step explanation:
All you have to do is divide 15.63 by 4. That way you will find out how much it costs for 1 pound of strawberries.
15.63 divided by 4 = 3.9075 ( I would round it but you don't have to.
Now look at the first 3 number for both prices
Grapes: $3.75
Strawberries: $3.90
Now you see which is less expensive ( grapes ). Now finish with a statement!
