What is the ratio?If b is not equal to 0, an ordered pair of numbers a and b, denoted as a / b, is a ratio. A proportion is an equation that equalizes two ratios. It is the contrast of two different quantities. For instance, if your father weighs 90 kg, and you weigh 30 kg, the weight ratio is 1:3.
Given:
x : (x + 3) = 2 : 3,
Calculate the value by simplifying the expression,
3x = 2 (x + 3)
3x = 2x + 6
x = 6

The number of CRT and LCD monitors in a company are in the ratio 2:5. If the total number of monitors in the company is 49, how many of them are LCD monitors?
Answer:
35 LCD monitors.
Step-by-step explanation:
The ratio is 2:5, which means the total amount of parts is 7 (2 + 5 = 7).
There are 49 monitors in all. Divide 49 with 7:
49/7 = 7
Each part has 7 monitors within. Remember, there are 5 parts of LCD monitors compared to 2 CRT monitors. Multiply 7 with 5:
7 x 5 = 35.
There are 35 LCD monitors, and 14 CRT monitors.

The shorter leg of a right triangle is 14 feet less than the other leg. Find the length of the two legs if the hypotenuse is 34 feet.
Answer:
side a = 30 feet long.and side b = 30-14 = 16 feet long.
Step-by-step explanation:
Right triangle, with sides a, b=a-14 and h=34
By Pythagorean rule, h2 = 342 = a2 + b2 = a2 + (a-14)2 ==> a2 + a2 - 28a + 196
Simplify to get 1156 = 2a2 - 28a + 196
Subtract 1156 from both sides to get 2a2 - 28a - 960 = 0
Divide all terms by 2: a2 -14a - 480 = 0
Use quadratic equation to find that a = 30 or a = -16.
a = -16 will not work.
Therefore side a = 30 feet long.and side b = 30-14 = 16 feet long.
Check: 302 + 162 = 900+256=1156. SQRT(1156) = 34 feet, the given hypotenuse.Right triangle, with sides a, b=a-14 and h=34
By Pythagorean rule, h2 = 342 = a2 + b2 = a2 + (a-14)2 ==> a2 + a2 - 28a + 196
Simplify to get 1156 = 2a2 - 28a + 196
Subtract 1156 from both sides to get 2a2 - 28a - 960 = 0
Divide all terms by 2: a2 -14a - 480 = 0
Use quadratic equation to find that a = 30 or a = -16.
a = -16 will not work.
Therefore side a = 30 feet long.and side b = 30-14 = 16 feet long.
Check: 302 + 162 = 900+256=1156. SQRT(1156) = 34 feet, the given hypotenuse.
The side length of the other sides is 30 feet and 16 feet if the shorter leg of a right triangle is 14 feet less than the other leg.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
It is given that:
The shorter leg of a right triangle is 14 feet less than the other leg.
From the Pythagoras theorem:
hypotenuse² = perpendicula² + base²
perpendicular = base - 14
34² = (base - 14)² + base²
34² = base² - 28base + 196 + base²
2base² - 28base - 960 = 0
base = 30, -16
side length cannot be negative
base = 30 feet
The length of another leg:
perpendicular = 30 - 14 = 16 feet
Thus, the side length of the other sides is 30 feet and 16 feet if the shorter leg of a right triangle is 14 feet less than the other leg.

Answer:

Step-by-step explanation:
2. If y varies inversely as the square root of x, find the percentage change in y when x is
increased by 21%.
The percentage increase in the value of y due to the increase in x by 21% is 10%
Inverse relationship :
y α 1/√ny = k/√x - - - - - - (1)
Increase in x by 21% = 0.21
y = k/√1+0.21x
y = k/√1.21x
y = k/ 1.1√x - - - (2)
Comparing the (1) and (2)
y has changed from 1 to 1.1
Increase in y = (1.1 - 1) = 0.1
Expressing the increase as a percentage :
0.1 × 100% = 10%
Hence, the percentage increase in y is 10%

For three consecutive even integers, -4 times the sum of the first and third integers is 192. What is the middle integer?
Answer: Middle integer = -24
Step-by-step explanation: First understand the formula for finding three consecutive even numbers.
Formula used: -4(n+n+4)=192
Let's solve your equation step-by-step.
−4(n+n+4)=192
Step 1: Simplify both sides of the equation.
−4(n+n+4)=192
(−4)(n)+(−4)(n)+(−4)(4)=192(Distribute)
−4n+−4n+−16=192
(−4n+−4n)+(−16)=192(Combine Like Terms)
−8n+−16=192
−8n−16=192
Step 2: Add 16 to both sides.
−8n−16+16=192+16
−8n=208
Step 3: Divide both sides by -8.
−8n
−8
=
208
−8
n=−26
Now find the middle integer.
Formula used: n+n+2+n+4
-26+(-26)+2+(-26)+4
-26+(-24)+(-22)
Middle integer=-24

Keith buys 3 yards of materials to make a blanket. He trims off a total of 1/6 yards before sewing. How much material remains for the blanket?
The number of yards of material remains sewing blanket is 2.5 yards.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given that, Keith buys 3 yards of materials to make a blanket.
He trims off a total of 1/6 yards before sewing.
So, 1/6 ×3
= 3/6
= 0.5 yards
Remaining material =3-0.5
= 2.5 yards
Therefore, 2.5 yards of material remain for sewing blanket.

Rotate MAP 90° degrees clockwise about point P. List the new ordered pairs.
Pre Image MAP:
M: (-3, 4)
A: (-7, 7)
P: (-7, -1)
Answer:
M' (-2 , -5), A'(1 , -1), P'(-7 , -1)
Step-by-step explanation:
Rotation clockwise 90° = rotation CCW 270°
Formula for rotation CCW 270° around a point (x',y') for original (x,y)
x'' = (x-x') cos 270° - (y-y') sin 270° + x'
y'' = (x-x') sin 270° + (y-y') cos 270° + y'
cos 270° = 0 and sin 270° = -1
x'' = - (y-y') sin 270° + x' = (y-y') + x'
y'' = (x-x') sin 270° + y' = (x'-x) + y'
M': x = (4 - -1) + (-7) = -2
y = (-7 - -3) + (-1) = -5
A': x = (7 - -1) + (-7) = 1
y = (-7 - -7) + (-1) = -1
check
P': x = (-1 - -1) + (-7) = -7
y = (-7 - -7) + (-1) = -1
-------------------------------------------------
Another way of thinking is to suppose P is (0,0) and locate other points' coordinate relative to P. Such as M(4,5), A(0,8)..
when it rotate CW 90° (x,y) -> (y , -x) will becomes (5 , -4) and (8 , 0). while (5 , -4) relative to p(-7 , -1) is (-7+5 , -1-4) i.e. ( -2 , -5) at original plane and (1 , -1) for point A'

A point estimate of the percentage of defectives in all manufactured bulbs is the Sample proportion.
How to find a point estimate of a proportion?
p'= x / n where x is the number of successes and n is the sample size. The variable p is the sample ratio and serves as a point estimate of the true ratio of the population.
Point estimation for population parameters is a single value for statistics. For example, the sample mean x is a point estimate of the population mean μ. Similarly, the sample ratio p is a point estimate of the population ratio P.
The average point estimate for the population is obtained by calculating the average of the samples taken from the population. The average calculation is the sum of all samples divided by the number of values.
