7. The students in Mr. Collin's class used a surveyor's measuring device to find the angle from
their location to the top of a building. They also measured their distance from the bottom of the
building. The diagram shows the angle measure and the distance.

To the nearest foot, what is the height of the building?
A. 239 ft
B. 154 ft
C. 67 ft
D. 33 ft
​

Answer:

The longest side is 16 cm

Step-by-step explanation:

[tex]x + (x + 2) + (x + 4) = 42cm \\ x + x + 2 + x + 4 = 42cm \\ 3x + 6 = 42cm \\ 3x = 36cm \\ x = 12[/tex]

check and finish

[tex]12 + (12 + 2) + (12 + 4) = 42cm \\ 12 + 12 + 12 + 6 = 42 cm\\ 36 + 6 = 42cm \\ 42cm = 42cm[/tex]

lengths of sides

[tex]12 + 4 = 16cm \\ 12 + 2 = 14cm \\ 12cm[/tex]

A point estimate of the percentage of defectives in all manufactured bulbs is the Sample 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.

Answer:

In fraction form, it would be 3/2

The percentage increase in the value of y due to the increase in x by 21% is 10%

Inverse relationship :

y = 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%

Step 3:- Divide both side of the inequality by -3 and flip the inequality sign.

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.

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:

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.

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'

Answer:

B and D are the correct answer

Step-by-step explanation:

I took the test

The difference in the starting salaries is $2,500 and Luisa will make more money in the first 8 years thus (B) and (D) are correct.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

Given salary of Luisa by function,

y = 36,000(1.025)^x

The starting salary of Luisa,

x = 0 → y = 36000(1.025)^0 = $36000

Starting salary Damon = $38500

Difference = 38500 - 36000 = $2500

Amount of money that Luisa make in first 8 years ⇒

36,000(1.025)¹ + 36,000(1.025)² + ...up to 8 times

Amount of money that Damon makes in first 8 years ⇒

38500 + (38500 + 800) + (38500 + 2 × 800) + ...up to 8 times.

The rate of increment of Luisa > Damon

Hence "The difference in the starting salaries is $2,500 and Luisa will make more money in the first 8 years".
