Answer:
[tex]x=4.5[/tex]
Step-by-step explanation:
From AAA, both triangles in this figure are similar. Therefore, we can set up the following proportion:
[tex]\frac{x}{9}=\frac{x+3}{15}[/tex] or [tex]\frac{x}{9}=\frac{3}{6}[/tex].
Cross-multiplying, we get:
[tex]6x=9(3),\\6x=27,\\x=\frac{27}{6}=\fbox{$4.5$}[/tex].

Pls help me! This is really hard.
Answers
1 meter is 100 centimeters (deci is 10, centi is 100, milli is 1000)
4.5 meter = 4.5 x 100 or 450 centimeters
(450/90)x100= 500%. 4.5 meters is 5 times longer than 90 cm
Cross check: 5x90=450
(90/450)x100= 20%
Cross check: .2x450=90

parker was able to pay 56% of his tuition with his scholarship .The remaining $6,057.35 he paid for with a student loan . What was the cost of parkers tuition ?
Answers
Answer:
$13,766.70
Step-by-step explanation:
Since he paid 56% with the scholarship, that means $6,057.35 is 44% of the total tuition
To find the total cost of tuition, divide 6,057.35 by 0.44
6,057.35/0.44
= 13766.70
So, the cost of Parker's tuition was $13766.70

X^2+3x+4=(x+a)^2+b what is A and B equal please help me
Answers
Answer:
a = 1.5, b = 1.75
Step-by-step explanation:
Expand the right side using FOIL, then compare the coefficients of like terms with the expression on the left side.
(x + a)² + b
= x² + 2ax + a² + b , then compare to
x² + 3x + 4
Comparing the coefficients of the x- terms
2a = 3 ( divide both sides by 2 )
a = 1.5
Comparing the constant terms
a² + b = 4
1.5² + b = 4
2.25 + b = 4 ( subtract 2.25 from both sides )
b = 1.75
Back in ye olden days, cell phone companies charged for texting. A cell phone company charges 10 cents per text message if a customer sends up to 100 messages per month, 8 cents for 101-200 messages, and 6 cents for 201-300 messages. If today is the last day of the month, and you've sent 200 texts, is it worth it to send 1 more text message?
Answers
Answer: It is worth it.
Step-by-step explanation:
If a customer sends 101 - 200 texts in a month, they get charged 8 cents per text.
If they send 201 - 300, they get charged 6 cents per month.
If you have sent 200 texts, your charge for the month will therefore be:
= 200 * 8
= $16.00
If you send the 201th text, you will be charged 6 cents per text. Total charge would be:
= 201 * 6
= $12.06
If you send 1 more text, it will be worth it because you will save:
= 16 - 12.06
= $3.94

A plot of land is in the shape of a triangle. Two of the angles measure 48 degrees and 74 degrees. The length of the side between them is 90 m.
a) calculate the perimeter of the plot, to the nearest meter.
b) calculate the area of the plot, to the nearest square meter.
Answers
Answer:
Perimeter = 271 meters
Step-by-step explanation:
third angle measure would have to be 180 - 122 = 58 degrees
you can use the law of sines:
sin 58° = sin 74°
90 b
.85 = .96
90 b
cross-multiply: .85b = 86.4
b = 102
now do again to find third side:
sin 58° = sin 48°
90 c
.85 = .74
90 c
.85c = 67
c = 79
now you know all 3 sides so add them to get perimeter (79+102+90) = 271

An information technology company produces 45% of its computer chips at a plant in St. Louis and the remainder of its chips at a plant in Chicago. It is known that 0.85% of the chips produced in St. Louis are defective, while 1.05% of the chips produced at the plan in Chicago are defective. What is the probability that a randomly chosen computer chip produced by this company is defective and was produced in St. Louis?
Answers
Answer:
the probability of the computer chip produced and defective is 0.003825
Step-by-step explanation:
The computation of the probability of the computer chip produced and defective is shown below
= Produced percentage × defective percentage
= 45% × 0.85%
= 0.003825
Hence, the probability of the computer chip produced and defective is 0.003825

Answer:
h = 14.5 ft
Step-by-step explanation:
Apply trigonometric ratio formula to find h:
reference angle = 46°
Opposite side = h
Adjacent side = 14 ft
Thus:
Tan 46 = h/14
Multiply both sides by 14
14*tan 46 = h
h = 14.4974243
h = 14.5 (nearest tenth)

What is the GCF of 6 and 36
Answers
Answer:
It's 6.
Step-by-step explanation:
6- 1, 2, 3, 6
36- 1, 2, 3, 4, 6
The greatest common factor of 6 and 36 is 6
Given data ,
Let the first number be represented as p
where the value of p = 6
Let the second number be represented as q
where the value of q = 36
To find the greatest common factor (GCF) of 6 and 36, we need to determine the largest positive integer that can divide both numbers evenly.
To begin, we can list the factors of each number:
Factors of 6 : 1 , 2 , 3 , 6
Factors of 36 : 1 , 2 , 3 , 4 , 6 , 9 , 12 , 18 , 36
From the lists, we can see that both 6 and 36 share a common factor of 6. The GCF of 6 and 36 is therefore 6, as it is the largest number that can evenly divide both 6 and 36.
Hence , the greatest common factor is 6
