What is the value of 19-7-15+14
Answer: the answer is 11 :)
Step-by-step explanation: I hope this helped!
Answer:
11
Step-by-step explanation:
19 - 7 = 12 - 15 = -3 + 14 = 11
or, if your brain likes it better, add the positives, then add the negatives, then subtract:
19 + 14 = 33
-7 -15 = -22
33 - 22 = 11

10) An architect is considering bidding for the design of a new shopping mall. The cost of drawing plans
and submitting a model is $10,000. The probability of being awarded the bid is 0.09, and anticipated
profits are
$100,000, resulting in a possible gain of this amount minus the $10,000 cost for plans and a
model. What is the expected value in this situation? Answers without any work shown will
receive no credit.
A) $8000
B) $9000
C) -$1000
D) $8100
Answer:
-$1000
Step-by-step explanation:
Given that:
Possible gain = 100,000 - 10,000 = 90,000
Loss =. 10,000 = cost of model submission
P(being awarded) = 0.09
P(not being awarded). = 1 - 0.09 = 0.91
X : 90000 _____ - 10,000
P(x) : 0.09 _______ 0.91
Expected value :
Σx*p(x) = (90000*0.09) + (-10,000 * 0.91)
= 8100 - 9100
= - 1000

x 120°
y = [ ? ]
Enter
9514 1404 393
Answer:
y = 95°
x = 60°
Step-by-step explanation:
The applicable theorem is the one that says the exterior angle (120°) is the sum of the remote interior angles:
120° = 25° +y
95° = y . . . . . . . . . . subtract 25° from both sides
_____
If you like, you can get there by calculating x (or not):
x = 180° -120°
y = 180° -25° -x = 180° -25° -(180° -120°)
y = 120° -25° . . . . . simplify — notice we didn't actually have to compute x
Simplify (y+1)+4

Answer: 1. P= 18m A= 72m
2. P= 7in A= 12 in
3. P= 18cm A= 81cm
Step-by-step explanation: For the P or Perimeter you need to add both of the numbers around the box. For A or the area you need to multiply the numbers on the box. You can also find that in the reading above the problem.

Firas and Nabil are comparing their bank accounts. "I have four times more money than
you" , Firas says. "Anyway, I have only $240 less than you" , Nabil answers .
How much money does each one of them have in his account ?
should be solved as a system
Answer:
Firas = $320
Nabil = $80
Step-by-step explanation:
Firas = 4x
Nabil = x
x + 240 = 4x
3x = 240
x = $80
Firas = $240 + $80 OR $80 x 3 = $320
Nabil = $80

The Pythagorean Theorem is
c² = g²-6²
False
O True
O No answer text provided.
O No answer text provided.
Answer:
FalseStep-by-step explanation:
It depends on the triangle.
If a is the longest side then it's true, but usually when we talk about Pythagorean theorem we mean that c is the longest side of the right triangle. So:
c² = a² + b²The width of a rectangle measures (8.1g-6.5)(8.1g−6.5) centimeters, and its length measures (4.7g-9.2)(4.7g−9.2) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer:
P = (25.6g - 31.4)
Step-by-step explanation:
Given that,
The width of a rectangle = (8.1g−6.5) cm
The length of a rectangle, = (4.7g−9.2)
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
Substitute all the values,
P = 2(8.1g−6.5+4.7g−9.2)
= 2(12.8g-15.7)
= 25.6g - 31.4
So, the perimeter of the rectangle is equal to (25.6g - 31.4).
What has an absolute value of 9?
Answer:
the first one 9 or -9
Step-by-step explanation:
they both have absolute values of 9
hope this helps :)
Answer:
Your answer would be 9 or -9.
Step-by-step explanation:
The absolute value of a number means the distance from 0. -9 is 9 units away from 0, as well as 9 itself. Hope this helps; have a great day!
Colin buys a tv for £800. It depreciates at a rate of 4% per year. How much will it be worth in 3 years? Give your answer to the nearest penny where appropriate
Answer:
£707.8
Step-by-step explanation:
Given data
Price= £800
Rate= 4%
Time= 3 years
Let us apply the compounding formula
A=P(1-r)^r-------------Note the negative sign is because of depreciation
substitute
A= 800(1-0.04)^3
A= 800(0.96)^3
A=800*0.884736
A= £707.8
Hence the value will be £707.8

Describe how your figure would translate given the rule. (x + 5, y - 3)
Answer: Translate 5 units to the right, 3 units down
=============================================================
Explanation:
The x+5 means we add 5 to each x coordinate. A point like (1,2) moves to (6,2) after adding on 5 to that coordinate. This visually means the point moves 5 units to the right.
The y-3 means we shift 3 units down because we subtract 3 from the y coordinate. So for example, the point (6,2) moves to (6,-1).
Overall, the rule [tex](x,y) \to (x+5, y-3)[/tex] means a point like (1,2) will move 5 units to the right and 3 units down to arrive at (6, -1). I recommend you try out more examples.

224 in 8 minutes. Use the unit rate to complete the table of values for the proportional relationship.
X. Y
2. ?
4. ?
6. ?
9514 1404 393
Answer:
see attached
Step-by-step explanation:
It can be convenient to use mental arithmetic methods* to fill in this table.
Since the relationship is proportional the y-value for x=4 will be half that for x=8, so will be 224/2 = 112. Similarly, the y-value for x=2 will be half that for x=4, so will be 112/2 = 56.
Then the y-value for x=6 will be the sum of the y-values for x=2 and x=4, so will be 112 +56 = 168.
If you actually care to find the "unit rate," you can divide the y-value for x=2 by 2 to get the corresponding y-value for x=1: 56/2 = 28. The unit rate is 28.

* Multiplication or division by 2 is simply a matter of doubling or halving. In most cases, it is easy to double a number, or to compute half of it. (If it isn't, you need to review your arithmetic facts.)
