Answer:
76 degrees
Step-by-step explanation:
The total of the three angles in a triangle should equal 180 degrees. So to find the third angle, subtract the two given angles from 180
180 - 87 = 93
93 - 17 = 76
The third angle is 76 degrees because then all angles will add up to 180

Step-by-step explanation:
Airplanes are sometimes used to fight fires. A certain airplane can deliver 4 x 10 liters of water in one trip. How much water can this airplane deliver in 34
trips?
Write your answer in scientific notation.
Answer
1360
Step-by-step explanation:
4x10 is 40 so you'd have to multiply 40x34 which is 1360
136×10 is the amount of water used by the airplane to deliver 34
trips.
What is Multiplication?Multiplication is a method of finding the product of two or more numbers
Given that Airplanes are sometimes used to fight fires.
A certain airplane can deliver 4 x 10 liters of water in one trip.
We need to find how much water can the airplane deliver in 34
trips
Let us find the water used for one trip.
1 trip is 4 x 10 liters which is 40 litres.
Now we have to find for 34 trips.
We have to multiply 34 with 40 litres
34×40
Thirty four times forty
1360
Now we have to convert it to the scientific notation 136×10
Hence, 136×10 is the amount of water used by the airplane to deliver 34
trips.

Question
On Saturday morning, it took Jennifer 3.6 hours to drive to her mother's house for the weekend. On Sunday evening, due to
heavy traffic, it took Jennifer 4 hours to return home. Her speed was 5 mi/hr slower on Sunday than on Saturday. What was
her speed on Sunday? Do not include units in your answer.
Provide your answer below:
FEEDBACK
Answer:
Speed of Jennifer on Sunday [tex]=45[/tex] mi/hr
Step-by-step explanation:
Let speed of Jennifer on Saturday be x mi/hr
On Saturday morning, it took Jennifer 3.6 hours to drive to her mother's house for the weekend.
Distance travelled by Jennifer on Saturday = Speed × Time [tex]=3.6x[/tex] miles
Speed of Jennifer on Sunday = [tex](x-5)[/tex] mi/hr
On Sunday evening, due to heavy traffic, it took Jennifer 4 hours to return home.
Distance travelled by Jennifer on Sunday = Speed × Time [tex]=4(x-5)[/tex] miles
As distance is obviously same on both Saturday and Sunday,
[tex]3.6x=4(x-5)\\3.6x=4x-20\\20=4x-3.6x\\20=0.4x\\x=\frac{20}{0.4}\\ x=50[/tex]
Therefore,
Speed of Jennifer on Sunday = [tex](50-5)=45[/tex] mi/hr

Use the literal equation m=5/4n-7 to find m when n =40
Help plz
Answer: 5/153
Step-by-step explanation:
Well, you'd just have to plug in 40 for n.
5/(40*4 - 7) = m
5/(160-7) = m
5/153 = m
An equation is formed of two equal expressions. As per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The value of m from the given equation can be found by substituting the value of n as 7 in the given equation as shown below.
m = (5/4)n - 7
Substitute the value of n as 40,
m = (5/4)40 - 7
m = (5/1)10 - 7
m = 50 - 7
m = 42
Hence, as per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.

Answer:
13.89 to 2 dec places.
Step-by-step explanation:
a7 / a5 = r^2 where r is the common ratio.
So 3/5 = r^2
r^2 = 0.6
r = +√0.6
r = 0.7746.
The first term is a5 / r^4
= 5 / (0.7746)^4
= 13.89.

Homework #1-18: Answer yes or no, if no give the reason
1) Is A ⊆ B given A = silver, B = {gold, silver, diamond}
A is not a set, so it can’t be a proper subset.
Answer: no, because A is not a set
3) Is C ⊆ D given C = {Phoenix}, D = {Phoenix, Glendale, Peoria, Scottsdale}
I need two rules to work.
C is a set so rule 1 is satisfied.
Every element of C is also an element of D, so rule 2 is satisfied.
Answer: yes
5) Is A ⊆ B given A = {2,3} , B = {1,2,3,4,5}
I need two rules to work.
A is a set so rule 1 is satisfied.
Every element of A is also an element of B, so rule 2 is satisfied.
Answer: yes
7) Is A ⊆ B given A = a, B = {| }
A is not a set, so it can’t be a proper subset.
Answer: no, because A is not a set
9) Is A ⊆ B given A = { }, B = {1,2,3,4,5}
Answer yes: the empty set is a subset of every set.
11) Is S ⊂ T given, S= ∅, T = {1,2,3,4,5}
Answer yes: the empty set is a subset of every set.
13) Is A ⊂ B given A = {1,2,3}, B = {3,2,1}
This is not a true statement. The sets are equal and this symbol does not allow sets to be equal.
Answer: no, sets are equal
15) Is C ⊂ D given C = {1,2,3,4,5}, D = {1,2,3,4}
Answer: no, C is not contained in D, so this is not true
17) Is A ⊂ B given A = {4,3,2,1 }, B = {1,2,3,4,5}
A is a set so rule 1 is satisfied,
A is contained in B so rule 2 is satisfied
A is not equal to B so rule 3 is satisfied
Answer: yes (all 3 rules are satisfied)

Santa Claus has been experiencing some recent back pain and is unable to carry large bags of toys over his shoulders. As a result, he has decided to use FedEx to deliver many of his gifts this year. FedEx charges a flat rate of $2.50 plus $0.85 per pound. If the cost of sending gifts to the Jones's was $28.85, how much did their gifts weigh?
Answer:
31 pounds
Step-by-step explanation:
From the information given, you can write the following formula to calculate the total cost of sending gifts:
Total cost of sending gifts=2.50+0.85x, where x is the weight of the gifts in pounds
Also, you know that the total cost of sending gifts is $28.85 and you can replace this value and solve for x:
28.85=2.50+0.85x
28.85-2.50=0.85x
26.35=0.85x
x=26.35/0.85
x=31
According to this, the answer is that the gifts weighed 31 pounds.
The Smith family and the Jackson family are having their basements remodeled. the Smiths contractor charge $16.50 an hour plus $289 in supplies. the Jackson’s contractor charge is $18.75 an hour and $274.60 and supplies. at how many hours of work with the total cost be the same for both families
Answer:
6.4 hrs
Step-by-step explanation:
16.5h + 289 = 18.75h + 274.6
16.5h-18.75h = 274.6-289
-2.25h=-14.4
h=14.4/2.25
h=6.4 hrs
check
6.4×16.5=105.6
105.6+289=394.6
18.75×6.4=120
120+274.6=394.6

28 coaches and 168 players
30 coaches and 180 players
Answer:
B :
26 coaches and 143 players
Step-by-step explanation:
Answer:
26 coaches and 143 players
Step-by-step explanation:
we can set up a proportion: [tex]\frac{coaches}{players}[/tex]
Our original proportions, 4/22 and 2/11 simplify to 2/11
We basically need a proportion that simplifies to 2/11, So let's simplify each proportion
24 coaches and 120 players: 24/120 simplified ⇒ 1/5
26 coaches and 143 players: 26/143 simplified ⇒ 2/11
28 coaches and 168 players: 28/168 simplified ⇒ 1/6
30 coaches and 180 players: 30/180 simplified ⇒ 1/6
The porportion, 26 coaches and 143 players simplifies to our orginal
proportion, 2/11, therefore it is proportional
