Answer:
6:25 PM
Step-by-step explanation:
Start of dinner
2:50 PM + 1:45 + 0:50
convert it to minutes
2:50PM + 60+ 45 + 50
= 2:50Pm + 60 + (50 + 10) + (45 - 10)
= 4:50Pm + 35
= 4:50PM + 10 + 25
= 5:25PM
End of dinner
5:25PM + 1 = 6:25PM

Answer:
(a) = 37π/180 radians
(b) = 37°
Step-by-step explanation:
Converting km/h ⇒ m/s :
⇒ 54 km/h x 5/18
⇒ 3 x 5
⇒ 15 m/s
===============================================================
Formula to calculate the angle :
⇒ tanθ = v/r
⇒ tanθ = (15 m/s)/(20 m)
⇒ θ = tan⁻¹ (0.75)
⇒ θ = 37°
=============================================================
Converting to radians :
⇒ Radian measure = Angle measure × π/180°
⇒ Radian measure = 37° × π/180°
⇒ Radian measure = 37π/180 radians
=============================================================
Solutions :
(a) = 37π/180 radians
(b) = 37°

How many hours and minutes is 125 minutes
Answer:
2 hours and 5 minutes.
Step-by-step explanation:
2 hours is 60mins+60mins which is equal to 120mins and then the extra 5mins
Hilary studied for a total of 2 hours and 5 minutes this week.
If Hilary studied for 25 minutes each day for five days this week, we can calculate the total study time by multiplying the number of minutes studied per day (25) by the number of days (5):
25 minutes/day × 5 days = 125 minutes
To convert this to hours and minutes, we need to divide the total minutes by 60 (since there are 60 minutes in an hour) to get the number of hours and find the remainder as minutes.
125 minutes ÷ 60 = 2 hours and 5 minutes
Therefore, Hilary studied for a total of 2 hours and 5 minutes this week.

I need the surface area
Answer:
Step-by-step explanation:
Front and back
Givens
base = 6 feet
height = 2
Formula
Area = 1/2 B * h
Area = 1/2 * 6 * 2
Area = (2) 1/2 * 12
Area = 12 square feet for both front and back
Base
The base is a rectangle. A rectangle has the formula of Area = L*w
Givens
L = 10 feet
W = 6 feet
Area = 10 * 6 = 60
Left roof
The left roof is also a rectangle. Area = L*w
Givens
L = 10 feet
W = 3 feet
Area = 3 * 10 = 30 feet^2
Right Roof
The right roof is a rectangle. Area = L*w
Givens
L = 10 feet
w = 4 feet
Area = 4 * 10 = 40 ft^2
Total area
Total Area = right roof + left roof + Base + front and back
Total Area = 40 + 30 + 60 + 12
Total Area = 142 feet ^2

Step 1: 4x+2y=14
Step 2: 2y=14-4x
Step 3: y=7-2x
Step 4: 3x-7-2x=23
Step 5: x-7=23
Step 6: x=30
In which step did Kendrick make an error? Explain.
The Kendrick made a mistake in step 4 he did not multiply the term (7 - 2x) with -1, and he wrote 3x-7-2x=23 instead of 3x -7 +2x = 23
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Kendrick was given the equations:
Step 1: 4x+2y=14 ...(1)
3x-y=23 ...(2)
From the equation first:
Step 2: 2y = 14 - 4x
Step 3: y = 7 - 2x put this value in the second equation
Step 4: 3x - (7 - 2x) = 23
Step 5: 3x -7 +2x = 23
Kendrick did a mistake in step 4 he did not multiply the term (7 - 2x) with -1
Thus, the Kendrick made a mistake in step 4 he did not multiply the term (7 - 2x) with -1, and he wrote 3x-7-2x=23 instead of 3x -7 +2x = 23

Find the value of m < 7 .
Answer:
B
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FES is an exterior angle of the triangle , then
57° + ∠ F = 142° ( subtract 57° from both sides )
∠ F = 85°
Answer: Option B: 85°
Step-by-step explanation:
Finding E: 142 + 180 + E = 360
360 - 142 - 180 = 32
E = 32
Finding F: 57 + 32 + F = 180
180 - 57 - 32 = 85
F = 85

Answer:
Step-by-step explanation:
Axel used the vertical line test on this graph, and decided it is a function because the vertical line only passes through one point, (3, 0).
On a coordinate plane, a circle is centered around (0, 0). A vertical line touches the edge of the circle at (3, 0).
Is Axel’s statement correct?
Answer: Axel's statement would be incorrect. (If this is for Edgenulty, the answer is C)
Step-by-step explanation: No, because the relation does not pass the vertical line test for every possible input.
Two parallel wires are separated by 0. 06 m, each carrying 3 a of current in the same direction. What is the magnitude of the force per unit length between the wires?
The magnitude of the force per unit length between the wires is [tex]3 \times 10^{-5} N/m[/tex].
What is the magnitude of the force?In a wire carrying a current I 2, the force that each wire feels due to the presence of the other depends on the distance between them and the magnitude of the currents.
Force per unit length = magnetic permeability * (current 1) * (current 2) / (2 π distance between the wires).
The below expression for the force per unit length.
Moreover, before using the below formula we have to change the unit centimeter into a meter. So, we just divide the centimeter by 100.
[tex]\rm \dfrac{Force}{length}=\dfrac{u_0 \times i _1 \times i_2}{2\pi d}\\\\\dfrac{Force}{length}=\dfrac{u_0 \times i _1 \times i_2}{2\pi d}\\\\Where; \ \mu_0 = 4\pi \times 10^{-7} , i_13 . \ i_2 = 3 \ d=0.06[/tex]
Substitute all the values in the formula
[tex]\rm\dfrac{Force}{length}=\dfrac{u_0 \times i _1 \times i_2}{2\pi d}\\\\Where; \ \mu_0 = 4\pi \times 10^{-7} , i_13 . \ i_2 = 3 \ d=0.06\\\\ \dfrac{Force}{length}=\dfrac{4\pi \times 10^{-7} \times 3 \times3}{2\pi \times 0.06}\\\\ \dfrac{Force}{length}= 3 \times 10^{-5} N/m[/tex]
Hence, the magnitude of the force per unit length between the wires is [tex]3 \times 10^{-5} N/m[/tex].

Answer:
The radius is 8.
Step-by-step explanation:
Because OA is a radius and AB is a tangent, Angle A is a right angle. So you can use Pythagorean theorem (shortcut Pythagorean triple)
OA^2 + 15^2 = 17^2
OA^2 + 225 = 289
OA^2 = 64
OA = 8
OA is a radius, the radius = 8

Doctors can use radioactive chemicals to treat some forms of cancer. The half life of a certain chemical is 5 days. A patient receives a treatment of 28 millicuries of the chemical. (A millicurie is a unit of radioactivity.) How much of the chemical remains in the patient 10 days later?
Answer:
7 millicuries
Step-by-step explanation:
A period of 10 days is 2 times the half-life of 5 days.
In the first 5 days, the amount of the chemical decayed by half from 28 millicuries to 14 millicuries. In the next 5 days, it decayed by half again, from 14 millicuries to 7 millicuries.
10 days later, 7 millicuries of the chemical remains.
