Answer:
It will take 8 minutes for the temperature to reach 76°
Step-by-step explanation:
The expression for the total temperature in degrees at time t can be written as;
T=I+EM
where;
T=total temperature
I=initial temperature
E=temperature increase per minute
M=number of minutes
This can also be written as;
total temperature=initial temperature+temperature increase per minute×number of minutes
In our case;
T=76°
I=40°
E=4.5°
M=m
replacing;
76=40+(4.5×m)
4.5 m=76-40=36
(4.5 m)/4.5=36/4.5
m=8
It will take 8 minutes for the temperature to reach 76°
Answer:
3,216 cm²
Step-by-step explanation:
The question is asking the surface area of a rectangular prism with the given dimension. That area is the sum of the areas of the 6 faces of the prism. Since opposite faces have the same area, we only need to compute 3 areas, then double the sum of those:
S = 2(LW +LH +WH)
This can be made a little easier to compute by some factoring:
S = 2(LW +H(L +W))
It does not matter which dimensions are designated length (L), width (W), or height (H).
__
S = 2((24 cm)(54 cm) +(4 cm)(24 cm +54 cm))
= 2(1296 +4(78)) cm² = 2(1608) cm²
S = 3216 cm²
The surface area of Emma's rectangular box is 3216 square centimeters.
The horizontal distance that's traveled by the golf ball based on the velocity given is 138.56feet.
<h3>How to compute the distance?</h3>
From the information given, the golf ball has been hit off of the tee at an angle of elevation of 30 degrees and an initial velocity of 160 ft/sec.
The distance will be:
= 160 × cos30°
=160 × 0.866
= 138.56 feet

Answer:
A. square.
B. rectangle.
C. the 2d shapes are different because squares and rectangles are not the same, the 3d shapes are the same (one is just rotated).
