Function f gives the temperature, in degrees Celsius, t hours after midnight. Choose the equation that represents the statement: “At 1:30 p.m., the temperature was 20 degrees Celsius.” Group of answer choices f (1:30) = 20 f (1.5) = 20 f (13:30) = 20 f (13.5) = 20
Answer:
D.
Step-by-step explanation:
The function f gives the temperature in degrees Celsius t hours after midnight.
Therefore, for the temperature at 12:00 AM (exactly midnight), we will have f(0).
For 1:00 AM, 1 hour after midnight, we will have f(1).
And for 12:00 PM (noon), we will have f(12).
We want to find the equation that represents the temperature at 1:30 PM.
1:30 PM is 13.5 hours after midnight or 1.5 hours after noon.
Therefore, the correct statement would be:
f(13.5)=20.
Hence, our answer is D.

Esteban stands on a dock 1.25 yd above the water. A fish swims below Esteban at -4.61 yd from the surface of the water. How many yards apart are Esteban and the fish?
Answer:
3.36 yards
Step-by-step explanation:
✓From the question, Esteban stands on a dock 1.25 yd above the water which means the distance of Esteban above the water is 1.25 yd
✓A fish swims below Esteban at -4.61 yd from the surface of the water which means the distance of the fish away from the surface is 4.61 yd in opposite direction of Esteban
NOTE: The negative sign only signify direction of the fish which is opposite of Esteban
✓then the distance in yards apart of Esteban and the fish is
=4.61-1.25
=3.36 yards

5) Ziegler is using paper for an art project
thatis 0.025 mm thick. If she glues a layer
of thepaper onto a construction board with
athickness of 7 * 10^-2 mm, what will the
total thickness of the paper and the
construction
board be? Write your ansicer
in scientific notation
Answer:
9.5 * 10^-2 mm
Step-by-step explanation:
To find the total thickness, we proceed to add the two thickness that we have
Mathematically, this will be;
0.025 mm + 7 * 10^-2 mm
7 * 10^-2 mm = 0.07
So we have;
0.025 mm + 0.07 mm = 0.095
In scientific notation, this is 9.5 * 10^-2 mm

Kara's car used 1/16 gallons
of gas to drive 1/8 of a mile. At
this rate, how many miles can
Kara's car drive using one
gallon of gas?
Cara deposited $200 dollars into her savings account bringing her balance up to $450. Which equation can be used to find, x, the savings account balance before the $200 deposit?
A x + 200 = 450
B x200=450
C x−200=450
D 200x = 450
Answer:
A. x + 200 = 450
Step-by-step explanation:
Since clara deposited $200 into her savings account and it brought her account up to $450, to find the answer you would add "x" with 200 and you should get 450 which means x= 250. we can check our answer by solving : 450-200 and you should get 250 for your answer so the answer is
A x + 200 = 450

how much is the arc of a circle if the angle is 70°
Answer:
siriously i dont know cuz im learning this in maths
area
perimeter
arc
Answer:
We also know that the sum of the measures of arcs AD, AB, CD, and BC must be 360 degrees, because there are 360 degrees in a full circle. Because AD = 2AB, we can substitute 2AB for AD. This means the measure of arc AB is 70 degrees, and the measure of arc AD is 2(70) = 140 degrees.

2x-y=1
x-y=-2
......................................
Answer:
y=5 x=3
Step-by-step explanation:
x-y=-2 move the y over to isolate x
x=-2+y Now plug that in for x in the first equation
2(-2+y)-y=1 Distribute
-4+y=1 Add 4 on both sides
y=5
x-5=-2
x=3
