Find the measure of b+d. A. 74 B. 90 C. 32 D. 58
Answer:
B. 90°
Step-by-step explanation:
Quadrilateral inscribed in the circle with center O is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
(b + d) + (32° + 58°) = 180°
b + d + 90° = 180°
b + d = 180° - 90°
b + d = 90°

d.If the Nelsons hire the design firm for 25 hours, then Rock the House Digital Designs will be cheaper.
Answer:
The correct statements are (a), (c) and (d).
Step-by-step explanation:
The information provided is:
Rock the House Digital Designs charges $500.00 for the initial consultation with the Nelsons plus $50.00 for every additional hour of work for the house plans.Elegant Home Architects charge $75.00 per hour for the house plans.The variable h represent the number of hours for which Mr. and Mrs. Nelson hire the design firm.The total charge for Elegance Home Architects, if the Nelsons choose them will be:
Total for Elegance = 75 × h = 75h.
Suppose the Nelsons hire the design firm for 15 hours.
Total for Elegance = 75 × h = 75 × 15 = $1,125
Total for Rock = 500 + (50 × h) = 500 + (50 × 15) = $1,250
So, the Elegance Home Architects will be cheaper.
Suppose the Nelsons hire the design firm for 25 hours.
Total for Elegance = 75 × h = 75 × 25 = $1,875
Total for Rock = 500 + (50 × h) = 500 + (50 × 25) = $1,750
So, the Rock the House Digital Designs will be cheaper.
Thus, the correct statements are (a), (c) and (d).

In Ms. Ford's classroom 13 students are able to fit comfortably into a 5 by 5 square.
Use this value to estimate the size of a crowd that is 10 feet deep on both sides of the street standing
along a 1-mile section of a parade route.
Answer:
Estimate of crowd is 27456.
Step-by-step explanation:
Given that a square of 5 by 5 can have 13 students.
Area of a square = [tex]side^2[/tex] = 25
Area of 25 can have 13 students.
Now, it is given that 10 feet square are used for crowd.
Area of square of side 10 feet = 100
So, area of 100 can have 13 [tex]\times[/tex] 4 = 52 people from crowd
Now, it is given that the parade route is 1 mile long.
1 mile = 5280 feet
1 mile = 528 [tex]\times[/tex] 10 feet
It means that there are 528 number of such squares on the 1 mile section of the parade route.
Kindly refer to the attached image as well.
So, number of people or the estimate of the size of crowd is:
528 [tex]\times[/tex] 52 = 27456

Suppose that a spotlight is used for lighting objects at many different distances and that the area A of the light circle produced is related to the distance x to the lighted object by A=0.1x^2.
a. If the spotlight produces 250 lumens of light energy, what function gives the intensity of the light I, (in lumens per square foot) as a function of the distance x in feet from the spotlight to its target?
b. Write and solve equations that match these questions about the light intensity from the spotlight.
i. What is the intensity of light on an object that is 20 feet from the spotlight source?
ii. How far from the spotlight is an object that recieves 100 lumens of light per square foot?
Answer:
Intensity = 2500/x^2
6.25 lumem
5 Feets
Step-by-step explanation:
Given the following :
Area (A) = 0.1x^2
Intensity, Energy and Area are related by the formular :
Intensity = power / Area
A) If 250 lumens of light energy is produced :
Intensity (I) = 250 / 0.1x^2
Intensity = 2500/x^2
x = distance
B) USING THE EQUATION :
1) What is the intensity of light on an object that is 20 feet from the spotlight source?
x = 20
Intensity = 2500/x^2
Intensity = 2500/20^2
Intensity = 2500/400
Intensity = 6.25 lumen
11) How far from the spotlight is an object that recieves 100 lumens of light per square foot?
Intensity = 100
100 = 2500 / x^2
100x^2 = 2500
x^2 = 2500/ 100
x^2 = 25
x = 5 Feets
Why is it important that the term “locked” is used when making the following statement? You can use a locked compass setting and a straightedge to draw two congruent segments.
You use a compass to draw an arc (or a full circle). The radius must be kept the same so that you can copy the length of the segment properly. If the compass could move freely, then it is unlikely the arc will be a piece of a circle, and rather some squiggly curve. So this is why the compass width must be locked into place.

Suppose the population of a town is 8,200 and is growing 4% each year, what is the population expected to be in 10 years
Answer:
12,138 people
Step-by-step explanation:
Create an equation using the basic exponential growth equation:
y = a(1 + r)^t, where a is the initial amount, r is the growth rate as a decimal, and t is the amount of time in years.
Plug in the values we know
y = a(1 + r)^t
y = 8200(1 + 0.04)^10
y = 8200(1.04)^10
= 12,138 people

Can someone answer these three questions? Thank you
Answer:
D, B, B
Step-by-step explanation:
Question 1: D
We need to solve for x.
z = 2π * (x / y)¹/²
z = 2π * (x¹/² / y¹/²)
z = 2π * (√x / √y)
z = √x * 2π / √y
√x = √y * (z / 2π)
x = y(z /2π)²
Question 2: B
(x⁵ + x⁴) / (x³ + x²)
= x⁴(x + 1) / x²(x + 1)
= x⁴ / x² = x⁽⁴⁻²⁾ = x²
Question 3: B
Let's try out A. Substituting p = 1, q = 1:
√1 * √1 = √(1 + 1)
1 * 1 = √2
1 = √2 FALSE
Let's try B. Substituting p = 2, q = 2:
√2 * √2 = √(2 + 2)
√4 = √4 TRUE so the answer is B.
What is the distance between y = 3x + 9 and y = 3x - 4?
Answer:
A. 4.11 units
Step-by-step explanation:
It can be convenient to put one of these equations into general form, then use the formula for the distance from a point to a line.
In general form, the first equation is ...
3x -y +9 = 0
So, the distance from a point to that line is ...
ax +by +c = 0 . . . . . . equation of a line
d = |ax +by +c|/√(a^2+b^2) . . . corresponding distance formula
d = |3x -y +9|/√(3^2 +(-1)^2)
Using the y-intercept of the other line as the point of interest, we find its distance to the first line to be ...
d = |3(0) -(-4)+9|/√10 = 13/√10 ≈ 4.11
The distance between the lines is about 4.11 units.
_____
Unless the lines are vertical or horizontal, you know the distance will be less than the difference between the x- or y- intercepts. Here, the y-intercepts are separated by 9-(-4) = 13 units. The x-intercepts are -3 and 4/3, so are separated by 4 1/3 units. Any answer choice larger than 4.33 cannot be correct.
A box is filled with 2 yellow cards, 4 blue cards, and 12 red cards. A card is chosen at random from the box. What is the probability that the card is not blue? Write your answer as a fraction in simplest form.
Answer:
7/9
Step-by-step explanation:
Given:
Number of yellow cards=2
Number of red cards=12
Number of blue cards=4
Total number of cards= Number of yellow cards+Number of red cards+Number of blue cards
= 2+4+12=18cards
Probability of a NON-blue card = number of non blue/ total number
where NON-blue= Number of red cards+
Number of yellow cards
= 2+12=14
P(not blue)=
=14/18
7/9
Therefore, probability that the card is not blue is 7/9
