If gdp is $20 trillion how many years will it take for a gdp to increase to 80$ trillion if growth is 7 percent
Answers
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

Dale plows his field at a constant rate of 18 mph. If Dale plows for 6 hours, how many miles of his field did he cover? A. 3 mi. B. 18 mi. C. 68 mi. D. 108 mi.
Answers
Answer:
108
Step-by-step explanation:
If Dale has a constant rate that means no matter how many hours, every hour he mows he will mow 18 miles. He mowed for 6 hours, so all you have to do is multiply 6*18, and your answer is 108 miles.

- A card is selected at random from a
standard pack of playing cards and then
replaced. This is done 1,040 times.
How many times would you expect to get
the following cards:
(a) A red card?
(b) A King?
(C) The Queen of hearts?
Answers
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
Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
1:Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.
2:Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
3:Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
4:Graph the function. On the graph, make sure to label the intercepts. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.
5:Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
Answers
Answer:
Answer:
1.) the y intercept is 490 and the slope is -2/3x
2.) First, I would find the point (0,490) and plot a point there. Then I would use our slope -2/3 to figure out what direction and what angle the line goes by counting 2 down and 3 to the right
3.) f(x)= -2/3x+490
The graph represents how many wraps could've been sold for each number of sandwich sales to keep the same profit of $1,470.
4.) graph down below
5.) the profits are the same (slope) but the y intercept is higher then the original graph.
6.) y=-2/3x+300
Step-by-step explanation:
some of these are part of the problem as well.
1.) 2x+3y=1,470
3y=-2x+1,470
-2x+1,470/3
-2/3x + 490
y=-2/3x + 490
the y intercept is 490 and the slope is -2/3x
2.) First, I would find the point (0,490) and plot a point there. Then I would use our slope -2/3 to figure out what direction and what angle the line goes by counting 2 down and 3 to the right
3.) f(x)= -2/3x+490
The graph represents how many wraps could've been sold for each number of sandwich sales to keep the same profit of $1,470.
5.) 2x+3y=1,593
3y=-2x+1,593
y=-2/3x+531
the profits are the same (slope) but the y intercept is higher then the original graph.
6.) (150, 200) (300, 100)
y intercept= 300
m= 100-200/300-150 = -100/150 = -2/3
y=-2/3x+300

Answers
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
(PLEASE ANSWER ASAP FOR BRAINILEST! EXPLAIN YOUR REASONING PLEASE) I bought 1 pound of grapes for $3.75. I bought 4 pounds of strawberries for $15.63. Which is least expensive per pound? Explain your reasoning.
Answers
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!

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
Answers
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.

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
