Answer:
The cost in 7 years will be of $384.69.
Step-by-step explanation:
Equation for exponential decay:
The equation for an amount after t years is given by:
[tex]A(t) = A(0)(1-r)^t[/tex]
In which A(0) is the initial value and r is the decay rate.
The cost of High Definition television now averages $1200, but the cost is decreasing by about 15% percent per year.
This means that [tex]A(0) = 1200, r = 0.15[/tex]. So
[tex]A(t) = A(0)(1-r)^t[/tex]
[tex]A(t) = 1200(1-0.15)^t[/tex]
[tex]A(t) = 1200(0.85)^t[/tex]
What will the cost be in 7 years?
This is A(7).
[tex]A(t) = 1200(0.85)^t[/tex]
[tex]A(7) = 1200(0.85)^7 = 384.69[/tex]
The cost in 7 years will be of $384.69.
in the bag, there are certain number of toy- blocks with alphabets A,B,C and D written on them. The ratio of blocks A:B:C:D is 4:7:3:1. if the number of A blocks is 50 more than the number of C blocks, what is the number of B blocks?
9514 1404 393
Answer:
350
Step-by-step explanation:
There are 4 ratio units of A blocks and 3 ratio units of C blocks, so 1 more ratio unit of A blocks than of C blocks. That 1 ratio unit corresponds to 50 blocks, since there are 50 more A blocks than C blocks.
There are 7 ratio units of B blocks, so the number of B blocks is ...
7×(50 blocks) = 350 blocks . . . . . number of B blocks

Step-by-step explanation:
in a rectangle ABCD in the figure shown ,what are the coordinates of vertex c
note : the figure shown in the image attached
helppppppp
Answer:
E. (7, 5)Explanation:
vertices C and D have the same coordinate x and x of D = 7
hence
x of C = 7
vertices A and D have the same coordinate y and y of D = 2
hence
m = 2
and
m+3 = 2+3 = 5
and since vertices B and C have the same coordinate y and y of B = 5
hence
y of C = 5
thus
coordinates x, y of C: (7, 5)
Round to the nearest tenth if necessary.

Which of the following represents a coefficient from the expression given?
5x - 21 + x2
Answer:
1 or 5
Step-by-step explanation:
A coefficient is "a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy)".
So, in this case, the coefficient of 5x would be 5.
The coefficient of x^2 would be 1.

what is 50.30 rounded to the nearest hundredth?
what is 50.20 rounded to the nearest hundredth?
what is 56.90 rounded to the nearest hundredth?
what is 49.50 rounded to the nearest hundredth?
what is 51.10 rounded to the nearest hundredth?
what is 30.00 rounded to the nearest hundredth?
Step-by-step explanation:
The hundredth place is the second number to the right of the decimal place (e.g., in ab.cd, where a, b, c, and d represent digits, the hundredth place is d).
When we round to the nearest hundredth, we remove all digits after the thousandth place. Then, if the thousandth place is 5 or greater, we remove it and add 0.01 (round up); if the thousandth place is 4 or lesser, we remove it (round down).
Thus:
50.30=50.30, as there is no thousandth place
50.20=50.20, same reasoning
56.90=56.90, same reasoning
49.50=49.50, same reasoning
51.10=51.10, same reasoning
30.00=30.00, same reasoning

A school sells adult play tickets for $7 and student tickets for the play for $4. If the school sold
420 student tickets, how many adult tickets were sold if the total sales for the play were $3010.
Answer:
190 adult tickets.
Step-by-step explanation:
Well,
420 × 4 = 1,680
3,010 - 1,680 = 1330
1330 ÷ 7 = 190.
So 190 adult tickets to the play were sold.

Answer: answer is -4 5/12
Step-by-step explanation:
Answer:
-4 - 5/12, or option 3.
Step-by-step explanation:
Change the denominator of each fraction to a common denominator. In this situation, the common denominator between the three fractions is 12.
- 7 2/3 = - 7 8/12
- 5 1/2 = - 5 6/12
8 3/4 = 8 9/12
Add them together.
-7 8/12 - 5 6/12 + 8 9/12 =
First, add the whole numbers together.
-7 - 5 + 8 - 8/12 - 6/12 + 9/12 =
-12 + 8 - 8/12 - 6/12 + 9/12 =
-4 - 8/12 - 6/12 + 9/12 =
Now, add the numerators of the fractions together.
-4 + (-8 -6 + 9)/12
-4 + (-5)/12 =
-4 - 5/12
The answer is -4 - 5/12, or option 3.

A farmer had 305 horses and 454 cows. Which of the following is a good estimation of how many horses and cows he had altogether?
600 horses and cows
700 horses and cows
650 horses and cows
750 horses and cows
850 horses and cows
____________________Solution :-Given Information :-Number of horses ➢ 305Number of cows ➢ 454 To Find :-Which of the following is a good estimation of how many horses and cows he had altogether?
600 horses and cows
700 horses and cows
650 horses and cows
750 horses and cows
850 horses and cows
Calculation :-Here, We will simply add up the number of animals ( cows and horses ) and then we will round it off to it's nearest 'tens' places.
⇒ Total number of animals = number of horses + number of cows
Substituting the values given, We get,
⇒ Total number of animals = 305 + 454
⇒ Total number of animals = 759
Now, when we round it off to it's nearest 'tens' places, We get,
⇒ Round off 759 = 750
Since, We can see that, 4th option from the list of option given, is 750. Therefore 750 is the answer.
____________________Final Answer :-4th option :- 750 horses and cows is the correct answer.____________________Which term of series1 +4+7+10+...is43
Answer:
a = 4
d = a2 - a1
d = 7 - 4
d = 3
an = 43
an = a + (n - 1)d
43 = 4 + (n - 1) 3
43 = 4 + 3n - 3
43 = 1 + 3n
43 - 1 = 3n
3n = 42
n = 42 ÷
n = 14
So, 14th term is 43

A bank loaned out $15,000, part of it at the rate of 7% per year and the rest at 17% per year. If the interest received in one year totaled $2000, how much was loaned at 7%?
How much of the $15,000 did the bank loan out at 7%?
9514 1404 393
Answer:
$5,500
Step-by-step explanation:
Let x represent the quantity loaned at 7%. Then the amount loaned at 17% is (15000-x), and the total interest is ...
0.07x +0.17(15000 -x) = 2000
-0.10x = -550 . . . . . . . . . collect terms, subtract 2550
x = -550/-0.10 = 5500 . . . . divide by the coefficient of x
The bank loaned $5,500 at 7%.

What is the measure of angle B in degrees?
Answer: how do I delete my answer?
Step-by-step explanation.
Here's the solution,
=》 C + 112° = 180°
( they form linear pair )
=》 C = 180° - 112°
=》C = 68°
And we know, measure of exterior angle if a triangle is equal to the sum of measures of the opposite interior angles,
So,
=》B = C + 51°
=》B = 68° + 51°
=》B = 119°
