Answer:
a. 12:10 pm
b. 40 mph
Step-by-step explanation:
Assuming you meant to type 1 ¹/₄ hours later.
a. First convert that to a improper fraction and then a decimal:
= 5/4
= 1.25 hours
1.25 hours in minutes is:
= 1.25 * 60
= 75 minutes
= 1 hour 15 minutes
The motorist left at 10:55.
= 1055 + 1 hour
= 11:55
Add 15 minutes:
= 12:10 pm
b. Speed = Distance / Time
= 50 / 1.25 hours
= 40 miles per hour
At x= pi/4 , find the product (sin4x)(cos5x)
Answer:
zeroStep-by-step explanation:
x= π/4
sin(4x)*cos(5x) =sin(4*π/4)*cos (5*π/4) =sin(π)*cos(5π/4)sin(π) = 0, therefore the product is also zero
Complete the table for the given rule.

Answer:
8units²
Step-by-step explanation:
Area of the trapezoid = 1/2(a+b)h
a and b are the opposite sides
h is the height
Take a square as 1 unit
a = 1 unit
b = 3 units
height h = 4 units
Substitute
A = 1/2(1+3)*4
A = 1/2 * 4 * 4
A = 16/2
A = 8units²
Hence the area of the trapezoid is 8units²

4x+3y=2
2x+y=6
substitution
Answer:
(8,-10)
Step-by-step explanation:
4x+3y=2
2x+y=6--->y=-2x+6
4x+3(-2x+6)=2
4x-6x+18=2
-2x=-16
x=8
4(8)+3y=2
32+3y=2
3y=-30
y=-10
Answer:
x=8 y=-26/3
Step-by-step explanation:
2x+y=6
2x=6-y
2x-6=-y
-2x+6=y
4x+3(-2x+6)=2
4x-6x+18=2
4x-6x+16=0
-2x+16=0
-2(x-8)=0
x-8=0
x=8
4(8)+3y=6
32+3y=6
26+3y=0
3y=-26
y=-26/3

Use the ruler provided to measure the radius of the circle to the nearest centimeter.
Which measurement is closest to the area of the circle in square centimeters?
Answer
its B
Step-by-step explanation:
Answer:
43.96 2 cm2
Step-by-step explanation:
For the given central angle, determine the distance traveled along the unit circle from the point (1, 0). 360 degrees a. 6.28 units clockwise c. 3.14 units clockwise b. 6.28 units d. 3.14 units
Answer:
The length of a 180° arc of a unit circle is π ≈ 3.14 units.
Step-by-step explanation:
Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to
... (180°/360°) × circumference = (1/2)×circumference
For a unit circle, the circumference is 2π (= π×diameter = 2π×radius). Half that length is π units.
Answer:
I can't give a "smart" explanation but the answer is D) 3.14 units

12 out of the 50 U.S. states have names that start with a vowel. What percentage of U.S. states' names start with a vowel
Answer:
24% of the U.S. states have names that start with vowels
Step-by-step explanation:
12 ÷ 50 = 0.24
0.24 × 100 = 24%
Answer:
24 % of the U.S. states' names start with a vowel
Step-by-step explanation:
12 out of 50 vcan be written in math terms as;
12 / 50 which equals the decimal form of a percent as shown;
12 / 50 = 0.24
which in percent form is: 24 %
what is the difference between multiplying fractions and adding/subtracting fractions? complete sentances pleaseo
Answer:
See explaination for answer! Hope this helps!
Step-by-step explanation:
When multiplying and deviding, you are raising them or lowering them by a certain degree, but adding or subtractions is just combining two fractions.
Just to quickly explain the "combining" aspect, during subraction, you are combining a positive with a negative.
