if ab=5 and a²+b²=25,then (a+b)² equals to.
Answers
Answer:
30
Step-by-step explanation:
Given
ab=5
a²+b²=25
So
(a+b)²=a²+ab+b²
=a²+b²+ab
=25+5
=30
Answer:
(a + b)² = 35
Step-by-step explanation:
Note the expansion of (a + b)²
(a + b)² = a² + b² + 2ab ← substitute given values
= 25 + 2(5)
= 25 + 10
= 35

Michael has a collection of 124 sports cards. He hopes to sell the collection in packs of 4 cards and make $496.31 when all the packs are sold. If each pack is priced the same, how much should Michael charge per pack?
Answers
Answer:
the price that Michael charge per pack is $16.01
Step-by-step explanation:
The computation of the price that Michael charge per pack is as follows:
= 124 sports card ÷ 4 cards
= 31 packs
Now the charge per pack would be
= $496.31 ÷ 31 packs
= $16.01
hence, the price that Michael charge per pack is $16.01
The same is to be considered
In the year 2009, a company made $8.4 million in profit. For each consecutive year
after that, their profit increased by 14%. How much would the company's profit be in
the year 2011, to the nearest tenth of a million dollars?
Answers
Answer:
$10.8 million or 10,752,000
Step-by-step explanation:
14% of 8,400,000 is 1,176,000
t = time in years
In one year, the company would make 8,400,000+(t*1,176,000)
In 2 years they make 8,400,000+(2*1,176,000) = 10,752,000
now round 10,752,000 to the nearest hundred thousand, which is 1/10 of 1,000,000.

The length and width of a rectangle, in terms of x, are x + 3 and 2x − 17, respectively. The area of the rectangle is 234 square units. (a) (6 points) DETERMINE the possible values of x
Answers
The possible values of x of a rectangle with length and width of x + 3 and 2x - 17 respectively is 15
Area of a rectangle
area of a rectangle = lw
where
l =lengthw = widthTherefore,
length = x + 3
width = 2x - 17
area = 234
Therefore,
234 = (x + 3)(2x - 17)
2x² - 17x + 6x - 51 = 234
2x² - 11x - 51 - 234 = 0
2x² - 11x - 285 = 0
Therefore,
(x - 15)(2x + 19)
Hence,
x = 15 or x = - 19 / 2
we can only use positive values. Therefore, x = 15

Explain what would happen to a figure if you transformed it using the rule(x-2,y+4). Then state whether the image would be similar, congruent, both, or neither.
Answers
Answer:
The figure would move 2 units to the left and 4 units up and the image would be congruent.
Step-by-step explanation:
If you transformed a figure using the rule (x-2, y+4).
Then the figure would move 2 units to the left (x-2) and 4 units up (x+4).
Similar figures would have the same shapes but different sizes.
Congruent figures would have the same shapes and same sizes but might be rotated.
Figures can not be both similar and congruent.
Moving the whole shape will not change the size; therefore, the figures would be congruent.

Explain how to write an equivalent expression by combining like terms.
w + 10 + w – 4
Answers
Answer:
To combine like terms, add the variable terms together and then add the constants together. When you combine the variable terms, you have 1w + 1w, which is 2w. When you combine the constants, you have 10 – 4, which is 6. The equivalent expression is 2w + 6.
Step-by-step explanation:
Answer:
add both "w" which equals 2w. Then add 10 and -4 which is 6. So the answer is 2w+6... I'm pretty that's the answer make sure to double-check though

What is the angle of elevation of a hill whose slope has a length of 345 feet and rises 87 feet?
A 14.2°
B 13.7°
C 14.6°
D
75.8°
Answers
The solution is, 14.6° is the angle of elevation of a hill whose slope has a length of 345 feet and rises 87 feet.
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
here, we have,
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
here, we have,
given that,
a hill whose slope has a length of 345 feet and rises 87 feet
now, we have to find the angle of elevation of a hill.
so, we get,
perpendicular = 87
hypotenuse = 345
let, the angle of elevation is θ.
we have,
sin θ = 87/345
so, we get,
θ = 14.6°
Hence, The solution is, 14.6° is the angle of elevation of a hill whose slope has a length of 345 feet and rises 87 feet.

At the beginning of the year, Alyssa had $100 in savings and saved an additional $7
each week thereafter. Colton started the year with $55 and saved $10 every week. Let
A represent the amount of money Alyssa has saved t weeks after the beginning of the year and let C represent the amount of money Colton has saved t weeks after the
beginning of the year. Write an equation for each situation, in terms of t, and determine the famount of money Alyssa and Colton have saved in the week that they have the same amount of money saved.
Answers
Answer:
A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.
Step-by-step explanation:
Given that:
Alyssa started savings with $100
Saved amount each week = $7
A = Amount of money Alyssa have
t = number of weeks
A = 7t + 100
Colton started savings with $55
Saved amount each week = $10
C = 10t + 55
For same amount;
A = C
7t+100 = 10t+55
100-55=10t-7t
45=3t
3t=45
Dividing both sides by 3
[tex]\frac{3t}{3}=\frac{45}{3}\\t=15[/tex]
Putting t=15 in Alyssa's equation
A = 7(15)+100
A = 105+100 = $205
Hence,
A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.

Answer:
BF = 18
Step-by-step explanation:
In triangle BCD, H is the Centroid.
Centroid of a triangle divides the median in the ratio 2 : 1.
Therefore, BH : HF = 2 : 1
Let BH = 2x & HF = x
Since, HF = 6.... (given)
So, x = 6
2x = 2*6 = 12
BH = 12
Now,
BF = BH + HF = 12 + 6
BF = 18
Each of five, standard, six-sided dice is rolled once. What is the probability that there is at least one pair but not a three-of-a-kind (that is, there are two dice showing the same value, but no three dice show the same value)
Answers
Answer:
The probability that there is at least one pair but not a three of a kind is 0.6944.
Step-by-step explanation:
We have the case when we have five dices and we roll them and we need that there is at least one pair but not a three of a king which is Two dice showing the same value, but no three dice showing the value.
Total no of outcomes = [tex]6^5 = 7776[/tex]
We will consider the other cases and then subtract them from the total outcomes.
No of outcomes of 5 of a kind = 6
No of outcomes 4 of a kind and 1 different = (6*5)*5 = 150
No of outcomes with 3 of a kind and 1 different pairs = (6*1*1*5*1)*5C2= 300
No of outcomes with 3 of a kind and two different = 6*5*4*10= 120*10=1200
No of outcomes when all are different = 6! = 720
These all the cases when subtracted from the total will represent the total cases in which there are two dice showing the same value.
Total cases = 6+150+300+1200+720
= 2376
Required no of outcomes = 7776-2376 = 5400
Probability = [tex]\frac{5400}{7776}[/tex] = 0.6944
Therefore the probability for the case of at least one pair but not a three of a kind is 0.6944.

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 1/5 ampere when the resistance is 8750 ohms. What is the current when the resistance is 17150 ohms?
Answers
Answer:
0.102048 ampere
Step-by-step explanation:
I α k / R
Current = 1/5 ; R = 8750
What is the current when the resistance is 17150 ohms
First obtain the value of k :
I = k/R
I = 1/5 ampere = 0.2 A
0.2 = k / 8750
k = 1750
What is the current when the resistance is 17150 ohms
I = 1750 / 17150
I = 0.1020408
I = 0.102048 ampere
