Answer:
m∠2=78°
Step-by-step explanation:
∡2=90°-∡1=90°-12°=78°, therefore ∡2=78°
The measure of ∠2 is 78°.
We have two angles ∠1 and ∠2 which are complementary angles such that ∠1 = 12°.
We have to find the measure of ∠2.
What are Complementary angles ?When the sum of two angles is equal to 90 degrees, they are called complementary angles.
∠X + ∠Y = 90
According to the question, we have -
The measure of angle ∠1 = 12°.
Assume that the magnitude of ∠2 is x.
Then -
∠ 1 + x = 90°
x = 90° - ∠1
x = 90° - 12°
x = 78°
Hence, the measure of ∠2 is 78°.

A baseball bat that originally sold for $65 is on sale at a 15% discount. Which single gift card amount would cover the complete cost of the discounted bat? Select all that apply.
A
$10
B
$15
C
$50
D
$60
E
$80
Answer:
A
$10
Step-by-step explanation:
15% of $65 is 9.75
so $10 would cover the given amount
We want to see which card can cover completely the cost of a bat after a discount is applied. We will see that the correct options are:
D and E.
The baseball bat is originally sold for $65.
It has a discount of a 15%, then the new price is given by:
P = $65*(1 - 15%/100%) = $65*(1 - 0.15) = $65*0.85 = $55.25
So the gift cards that cover the whole cost of the discounted bat are these ones with a value equal or larger than $55.25
The correct options are:
D: $60
E: $80
With these two you could pay the complete cost of the discounted bat.

Joe is shopping for gifts. Coffee mugs are on sale for $4 off the regular price, p. Joe buys 6 mugs. He pays a total of $54. What is the regular price of a coffee mug
Answer: 13
Step-by-step explanation:
add 24 to 54 and you get 78. divide that by 9 and you get 13.
24 is the total price off
54 is the total he pays
add 54 and 24 to get 78, the original total without any off
9 is the amount each cup costed with the 4 dollars off
divide 78 by 9
13 would be the answer
13- 9 is also 4 dollars

Find the gradient of the curve y = x^5/2 at the point where x = 4
Given:
The equation of the curve is:
[tex]y=x^{\frac{5}{2}}[/tex]
To find:
The gradient of the given curve at the point where [tex]x = 4[/tex].
Solution:
We have,
[tex]y=x^{\frac{5}{2}}[/tex]
Differentiate with respect to x.
[tex]y'=\dfrac{5}{2}x^{\frac{5}{2}-1}[/tex] [tex][\because \dfrac{d}{dx}x^n=nx^{n-1}][/tex]
[tex]y'=\dfrac{5}{2}x^{\frac{3}{2}}[/tex]
Substituting [tex]x=4[/tex], we get
[tex]y'=\dfrac{5}{2}(4)^{\frac{3}{2}}[/tex]
[tex]y'=\dfrac{5}{2}(2^2)^{\frac{3}{2}}[/tex]
Using properties of exponents, we get
[tex]y'=\dfrac{5}{2}(2)^{2\times \frac{3}{2}}[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]y'=\dfrac{5}{2}(2)^{3}[/tex]
[tex]y'=\dfrac{5}{2}(8)[/tex]
[tex]y'=20[/tex]
Therefore, the gradient of the given curve at the point where [tex]x = 4[/tex] is 20.
A video game originally costs $63, but if you buy it before the end of May there is a 25% off sale. The sales tax is 9.5%. What is the final price of the video game if you buy it before the end of May?
Answer: $53.24
Step-by-step explanation:
Find the sales tax:
9.5*63.00=598.5
Then divide 598.5 by 100: 598.5/100= 5.985
Round: $5.99 ( sale tax amount )
Now we find the discount: 25*63.00= 1,575
Then divide it by 100 : 1,575/100= $15.75 ( discount amount )
Take the original price of the game and subtract it by the discount amount, then add the sales tax amount: 63.00-15.75= 47.25+5.99= $53.24
Answer: $53.24

Step-by-step explanation:

Hey There!
What we want to do to find how many supply boxes can fit inside of the larger box is find the volume of the larger box and divide that by the volume of the supply boxes.
To find the volume of the supply boxes:
We are told that the supply box is in the shape of a cube.
That being said we can find the volume by using this simple formula
[tex]V=s^3[/tex]
where s = side length
The supply box has a side length of 4.5 so we just plug in 4.5 into the formula
[tex]V=4.5^3\\4.5*4.5*4.5=91.125[/tex]
So we can conclude that the volume of the supply box is 91.125 square inches.
Now to find the volume of the larger box.
The larger box is in the shape of a rectangular prism.
The volume of a rectangular prism can be found by multiply the width by the length by the height.
The box has the following dimensions:
width = 18 in
height = 4.5 in
length = 9 in
This means that the volume = 9 * 4.5 * 18
9 * 4.5 = 40.5
40.5 * 18 = 729.
so the volume of the larger box is 729 square inches.
Now we want to find how many little boxes can fit inside the larger box.
Like stated before this can be done by dividing the volume of the little boxes by the volume of the larger box
so # of supply boxes that can fit inside of the larger box = [tex]\frac{729}{91.125}[/tex]
Using a calculator: [tex]\frac{729}{91.125} =8[/tex]
Hence, 8 smaller boxes can fit inside of the larger box

Answer:
the answer to number one is 18.5. i'm not sure about two or three, sorry.
Step-by-step explanation:
1. I think you can use the formula for speed:
speed = distance / time
2. Transpose the equation to find distance and you'll get:
distance = speed x time
3. Substitute the given inputs...
distance = (40 m/s)(0.4625s)
4. Cancel "s".
distance = (40m)(.4625)
5. Calculate.
distance = 18.5 m -- ANSWER
1) The distance be 18.5 meter.
The Velocity of ball is v = 40.0 m/s and it taking t = 0.4625 seconds to arrive at home plate.
What is the relation between velocity, distance and time?
Velocity equals distance travelled divided by the time it takes to get there.
Now,
Velocity = distance/ time
So, Distance = time x velocity
⇒ Distance = 0.4625 x 40.0
= 18.5 m
Thus, the distance be 18.5 meter.
2) Distance of the signal travel is [tex]24 *10^{6}[/tex] [tex]km/sec^{2}[/tex].
Here, Speed of radio signal is 300,000 km/s
Time taking in travel is 80 second.
Speed = distance/ time
Distance = speed x time
= 300,000 x 80
= 24,000,000
Hence, Distance of the signal travel is [tex]24 *10^{6}[/tex] [tex]km/sec^{2}[/tex].
3) Time taking to elapses before it strikes a target is 4.06 second.
Here, Speed of bullet is 1230 m/s
Distance travel by bullet is 5000m
Now,
Speed = distance/ time
Time = distance / speed
= 5000/1230
= 4.06 second
Hence,
Time taking to elapses before it strikes a target is 4.06 second.
