Answers
Answer:
Hi there! The answer is B: 45 Miles/Hour (or mph)
Step-by-step explanation:
When looking at speed signs in the U.S. they always use miles per hour, or MPH. Making it so the other options are incorrect!
Hope this helps!! :)
The most common unit on a U.S. speed limit sign is B. 45 miles/hour. Speed limits are displayed in miles per hour, not in units like miles per day, miles per second, or feet per second.
The value you would most likely see on a U.S. speed limit sign is B. 45 miles/hour. In the U.S., speed limits are almost always shown in miles per hour (mi/h). Therefore, options like 150 miles/day, .08 miles/second, or 25 feet/second are not standard measurements for speed limits on road signs.
To address the conversion exercises, converting 80 km/h to metric units of meters per second (m/s), you use the conversion factor 1 km/h = (1/3.6) m/s. So, 80 km/h equals approximately 22.2 m/s. The conversion to imperial units of miles per hour requires knowing that 1 km is roughly 0.621 miles, making 80 km/h about 49.7 mi/h.
Similarly, 100 km/h equals about 27.8 m/s (not an option here), and in miles per hour, it's approximately 62 mi/h. When converting from metric to imperial or vice versa, it's useful to remember that 1 m/s equals 3.6 km/h and roughly 2.2 mi/h.

Joseph measured his height and found out that he was 5.9 feet tall. There are about 0.304 meters in 1 foot. About how many
meters tall is Joseph?
Answers
The height of Joseph in meters is 1.79 m.
What is Height?
Height, altitude, elevation mean vertical distance either between the top and bottom of something or between a base and something above it. Height refers to something measured vertically whether high or low.
Here, Height of Joseph = 5.9 ft.
1 feet = 0.304 m
5.9 ft = 0.304 X 5.9 m.
5.9 ft = 1.79 m.
Thus, the height of Joseph in meters is 1.79 m.

What is its radius?
If necessary, round your answer to two decimal places.

Answers
radius = √26 = 5.099 = 5.1
As per the equation of the circle, the center of the circle is (-1.6, -9.8) units, and its radius is approximately 5.10 units.
The standard form of the equation of a circle is (x - h)² + (y - k)² = r², where (h, k) represents the center of the circle, and r is the radius. By comparing the given equation with the standard form, we can easily identify the values of h, k, and r.
Comparing the given equation
=> (x + 1.6)² + (y + 9.8)² = 26
with the standard form, we find that h = -1.6 and k = -9.8.
These values represent the x-coordinate and y-coordinate of the center of the circle, respectively.
To find the radius, we need to take the square root of the constant term on the right side of the equation.
R² = 26
r = √26 ≈ 5.10 (rounded to two decimal places)

Find the sum of the areas of a kite with diagonals of 28 and 32 inches and a rhombus with diagonals of 37 and 63 inches. Round answer to the nearest tenth of a square inch.
Answers
Answer:
total area = K + R = 448 + 1,165.5 = $1,613.5 sq. in.
Step-by-step explanation:
Use formulas for area of Kite and area of rhombus.
K = area of Kite
R = area of rhombus
K = (1/2) *(diagonal 1)*(diagonal 2)
R = (1/2)*(diagonal 1)*(diagonal 2)
K = (1/2)*(28 in.)*(32 in.) = 14 * 32 = 448 sq. in.
R = (1/2)*(37 in.)*(63 in.) = 1,165.5 sq. in.
total area = K + R = 448 + 1,165.5 = $1,613.5 sq. in.

To calculate the cost of painting his silo, a farmer must find its height. The farmer uses a cardboard square to line up the top and bottom of the silo as shown in the diagram below. Approximate the height of the silo, rounded to the nearest foot.
Answers
By calculating angles and side lengths using trigonometric ratios and the Pythagorean theorem, we determined that the height of the silo (length CE) is approximately 18 feet.
Calculate angle ACD using the tangent trigonometry ratio:
Given AD = 8 feet and DP = 5 feet, we find C using tan(C) = AD/DP, which gives C = arctan(8/5) = 32 degrees.
Calculate angle BCA:
BCA = 90 - 32 = 58 degrees.
Calculate side length AC using the Pythagorean theorem:
Given AB = 5 feet and BC = 8 feet, AC^2 = AB^2 + BC^2, so AC = sqrt(89) = 9.4 feet.
Calculate the height of the silo (length CE) using the cosine ratio:
With AC = 9.4 feet and BCA = 58 degrees, cos(58) = BC/AC = CE/9.4. Solving for CE, we get approximately 17.7 feet.
Therefore, the height of the silo is approximately 18 feet.

Joanna went to school supply shopping. She spent $31.80 on notebooks and pencils. Notebooks cost $2.05 each and pencils cost $1.50 each. She bought a total of 19 notebooks and pencils. How many of each did she buy?
A.
11 notebooks; 8 pencils
B.
9 notebooks; 10 pencils
C.
6 notebooks; 13 pencils
D.
4 notebooks; 15 pencils
Answers
Answer:
C
Step-by-step explanation:
Total number of notebooks and pencils= 19
Assuming that she bought notebooks only,
amount spent
= 19($2.05)
= $38.95
Difference in actual amount spent
= $38.95 -$31.80
= $7.15
This difference in amount is due to the number of wrong assumptions we have made previously, such that we assumed that a certain number of pencils that she bought was notebooks. Thus, let's find the number of wrong assumptions so we can find out how many pencils she bought.
Cost difference of each notebook compared to a pencil
= $2.05 -$1.50
= $0.55
This means that for each wrong assumption, there is an additional $0.55 in the total amount Joanna spent.
Number of sets of extra $0.55
= $7.15 ÷$0.55
= 13
Thus, she bought 13 pencils.
Amount of notebooks bought
= 19 -13
= 6
Let's check our work!
If Joanna bought 13 pencils and 6 notebooks,
total amount spent
= 13($1.50) +6($2.05)
= $19.50 +$12.30
= $31.80
Thus option C is indeed correct as it is given from the question that she spent $31.80.
