Answer:
b ≈ 8.49
Step-by-step explanation:
A^2 + b^2 = c^2. (Pythagorean theorem)
c is the hypotenuse or the longest side of a triangle.
a and b are the other 2 sides.
17^2 + b^2 = 19^2
289 + b^2 = 361
289 + b^2 - 289 = 361 - 289
b^2 = 72
b ≈ 8.49

SNACKS The face of the popcorn box can be modeled with an isosceles trapezoid with QR=3x+2.5, RS=9x−4.8 , ST=4x−2 , and QT=6x+1.2.
Answer:
TQ=SR [since it is isosceles trapezoid]
6x+1.2=9x-48
48+1.2=9x-6x
3x=49.2
x=49.2/3=16.4
now
QR=3×16.4+2.5=51.7
SR=9×16.4-48=99.6
ST=4×16.4-2=63.6
TQ=6×16.4+1.2=99.6
As it's isosceles trapezoid
QT=RS9x-4.8=6x+1.23x=6x=2Now
QR=3(2)+2.5=8.5
RS=9(2)-4.8=13.2
ST=4(2)-2=6
QT=6(2)-1.2=10.8
Please help will mark Branliest!! Determine if the problem is a permutation or a combination. Then find the number of possibilities. image attached. This is a combination/permutation and the answer ___.
Answer:
It is a permutation problem. There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.
Step-by-step explanation:
In this case, the company will hire four different applicants from a group of 40 people for 4 different jobs. In this case, we need to consider the effect of order in the number of possibilities. Hence, we must use the permutation formula:
[tex]_{n} P_{k} = \frac{n!}{(n-k)!}[/tex] (1)
Where:
[tex]n[/tex] - Total of applicants.
[tex]k[/tex] - Selected applicants.
If we know that [tex]n = 40[/tex] and [tex]k = 4[/tex], then the number of possibilities is:
[tex]_{40}P_{4} = \frac{40!}{(40-4)!}[/tex]
[tex]_{40}P_{4} = 40\times 39 \times 38 \times 37[/tex]
[tex]_{40}P_{4} = 2193360[/tex]
There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.
A plane is travelling at 180 metres per second. How many minutes will it take for the plane to travel 800km? Give your answer in the nearest minute.
Answer:
79 minutes
Step-by-step explanation:
A plane is travelling at 180 meters per seconds
Convert to km/hr
180× 18/5
= 648 km/hr
Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is
= 1/648 × 800
= 1 hour 19 minutes
Conver the time to full minutes
60 minutes = 1 hour
= 60+19
= 79 minutes
Hence the minutes required for the plane to travel 800km is 79 minutes

x = 10.2
The value of x with the help of sine law is 10.2 units.
What is Sine Law?
Law of sines defines the ratio of sides of a triangle and their respective sine angles are equivalent to each other. The other names of the law of sines are sine law, sine rule and sine formula.
Here, Law of sines:
[tex]\frac{Sin A}{a} =\frac{Sin B}{b} = \frac{Sin C}{c}[/tex]
sin 30° / x = sin 69° / 19
1/2x = sin 69° / 19
cross-multiply:
19/2 = sin 69°x
x = 9.5 / sin 69°
x = 9.5/0.934
x = 10.2
Thus, the value of x with the help of sine law is 10.2 units.

A rectangular container with a base of 24 inches by 15 inches is 1/3 filled with water. If all the water is poured into an empty rectangular container measuring 12 inches by 18 inches by 10 inches, it will fill the second container to its brim. What is the height of the first container?
Answer:
18 inches
Step-by-step explanation:
volume of a cuboid = length x breadth x height
the following equation can be derived from the question
let h = unknown height
1/3(24 x 15 x h) = (12 x 18 x 10)
Multiply both sides of the equation by 3
(24 x 15 x h) = (12 x 18 x 10) x 3
Divide both sides of the equation by (24 x 15)
h = 18 inches

A community pool charges $78 for swim lessons and a $2 towel rental fee per day. At the end of the summer Yolanda spends $102. How many days did Yolanda go for swim lessons?
Answer: 12 days
Step-by-step explanation:
Given
A community pool charges $78 for a swim lesson and $2 for a towel each day
Suppose Yolanda attended the session for x days
So, we can write the total fees of $102 as
[tex]\Rightarrow 102=78+2x\\\Rightarrow 2x=102-78\\\\\Rightarrow x=\dfrac{24}{2}\\\\\Rightarrow x=12[/tex]
So, Yolanda attended the swim lessons for 12 days

Vertex form of an equation
Given the expression [tex]f(x) = x^2 + x +1[/tex]
The vertex form is expressed as shown below:
[tex]f(x) = x^2 + x +1\\f(x) = x^2 + x + 1^2 +1 - 1^2\\f(x) = (x+1)^2 - 0[/tex]

A cooler shape of a rectangular prism. What is the volume of the cooler? Round to the nearest tenth if necessary.
Answer:
Volume of the cooler = 2,772 in³
Step-by-step explanation:
Volume of the cooler = length × width × height
Length = 22 in
Width = 12 in
Height = 10 1/2 in
= 21/2
= 10.5 in
Volume of the cooler = length × width × height
= 22 in × 12 in × 10.5 in
= 2,772 in³
Volume of the cooler = 2,772 in³
∠1 and ∠2 are supplementary angles. ∠1 and ∠3 are vertical angles. If m ∠2=72 degrees, then find m ∠3
Answer:
m<3 = 108
Step-by-step explanation:
Since <1 and <2 are supplementary, the equation is:
<1 + <2 = 180
Since <1 and <3 are vertical angles. the equation is:
<1 = <3
To find m<3:
<2 + <3 = 180
72 + <3 = 180
<3 = 180 - 72
<3 = 108
The measure of angle ∠3 is 108 degrees.
What is supplementary angle?Supplementary angles are those angles that sum up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees.
What is vertical angle?Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.
For the given situation,
∠1 and ∠2 are supplementary angles.
∠1 and ∠3 are vertical angles.
Measure of angle, m ∠2 = 72
From definition, we know that
∠1 + ∠2 = 180 (supplementary angles) ------- (1)
and
∠1 = ∠3 (vertical angles) --------- (2)
From (1) and (2),
⇒ [tex]\angle3 + \angle2 = 180[/tex]
⇒ [tex]\angle3=180-72[/tex]
⇒ [tex]\angle3=108[/tex]
Hence we can conclude that the measure of angle ∠3 is 108 degrees.
