The distance a jet travels varies directly with the number of hours flown. A jet travels 1,350 miles in three hours. If the jet continues to travel at the same rate, how far will it fly in seven hours?
Answer:
3150
Step-by-step explanation:
1350/3= 450
1350+1350+450= 3150
The first term of an arithmetic progression is 80 and the common difference is -3. what is the greatest possible sum of the first n terms of this sequence, and for which value of n does it occur?
I need help with this question, in advance thank you :)
Answer:
S=157
Step-by-step explanation:
an= a1+(n-1)d
a2=80+(2-1)(-3)
a2=80-3
a2=77
Sn=(a1+an)*n/2
S2=(80+a2)*2/2
S2=(80+77)*1
S2=157

Answer:
3x+30= 116° 2x=64°
Step-by-step explanation:
the angle below 2x is the same as 3x+20 so we know that 5x+20=180 so solve this
5x+20=180
5x=160
x=32
sub x into the angle equations
3(32)+20=116
2(32)=64
Answer:
x=32°
Step-by-step explanation:
3x+20+2x=180°(being co interior angle)
3x+2x+20=180°
5x=180-20
5x=160
x=32°

Line f passes through points (92, 19) and (-4, 94). Line g is perpendicular to f. What is the slope of line g?
Answer:
1.28
Step-by-step explanation:
slope of line f = (94 - 19)/(-4 - 92) = -75/96
since line g is perpendicular to line f, the product if their slope = -1
therefore, 75/96 x slope of line g = -1
slope if line g = -1/(-75/96) = 96/75 = 1.28

Determine if the side lengths could form a triangle. Use an inequality to prove your answer.
a) 16 m, 21 m, 39 m
b) 34 km, 27 km, 58 km
c) 29 ft, 38 ft, 9 ft
9514 1404 393
Answer:
a) no
b) yes
c) maybe (no)
Step-by-step explanation:
There are two versions of the triangle inequality. One requires ...
a + b > c
for any triple of side measures a, b, c.
The other allows ...
a + b ≥ c
which admits "triangles" that have zero height and look like line segments.
Most questions asking "do these lengths form a triangle" are concerned with the "greater than" case, and disallow the "or equal to" case.
__
a)
[tex]16+21=37\ngtr39\qquad\text{not a triangle}[/tex]
b)
[tex]27+34=61>58\qquad\text{could be a triangle}[/tex]
c)
[tex]9+29=38\ge38\qquad\text{could be a triangle if "equal to" is allowed}[/tex]

Select all of the ratios that are equivalent to 6:3?
Answer: We can't see the ratios.
Step-by-step explanation:
A 2-column table with 3 rows. Column 1 is labeled Days, x with entries 3, 4, 5. Column 2 is labeled Miles, y with entries 771, 973, 1,175.
The Boden family is taking a road trip across the US. After initially driving for awhile, the Bodens decide to make a plan to drive a set number of miles each day. Days 3, 4, and 5 are displayed in the table. Assume the relationship is linear.
Identify how many miles per day the Boden family is planning to travel.
miles per day
Answer:
202 miles per day
Step-by-step explanation:
Answer:
165
Step-by-step explanation:
A 2-column table with 3 rows. Column 1 is labeled Days, x with entries 3, 4, 5. Column 2 is labeled Miles, y with entries 771, 973, 1,175.
The Bodens drove for awhile before they made a plan to drive a set number of miles each day. Days 3, 4, and 5 are displayed in the table. Assume the relationship is linear.
Determine the initial number of miles that the Boden family drove before they made their plan.
771 miles
367 miles
165 miles
135 miles
This is your correct answer 165, oops this is the wrong question sorry
solve for x plsssssss
Answer:
x = 129º
Step-by-step explanation:
It will take some time to elaborate but start this way:
you see the triangle with the 58º and 57º? Now by rule, the sum of all angles ina triangle is 180º
so 57+58 = 115
to discover the other angle you just have to 180-155 = 65
Now that you know the 65º by rule the angle facing it is exactly the same, follow from there, solve all triangles until you get to x...

help find missing segment??
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Let x as the missing segment.
_________________________________
According to the Thales theorem :
[tex] \frac{26}{x} = \frac{12}{36} \\ [/tex]
[tex] \frac{26}{x} = \frac{12}{12 \times 3} \\ [/tex]
[tex] \frac{26}{x} = \frac{1}{3} \\ [/tex]
Inverse both sides
[tex] \frac{x}{26} = \frac{3}{1} \\ [/tex]
[tex] \frac{x}{26} = 3 \\ [/tex]
Multiply sides by 26
[tex]26 \times \frac{x}{26} = 26 \times 3 \\ [/tex]
[tex]x = 26 \times 3[/tex]
[tex]x = 78[/tex]
Thus the missing segment has a measure of 78 .

Sara owns a paint shop that makes custom paints. To make one gallon of a specialty color, she needs 4 royal blue units that each cost $b. She also needs 9 yellow units that each cost $y. A customer orders 4 gallons of this paint.
Sara uses the expression 4(4b + 9y) to find the total cost for the color units needed to make each gallon of paint.
Explain how to write an expression that is equivalent to the total cost expression. Then determine the total cost for the color units needed to make the paint if each royal blue color unit costs $0.30 and each yellow unit costs $0.10.

A mixture of 30 pounds of candy sells for $1.10 a pound. The mixture consists of chocolates worth $1.50 a pound and chocolates worth 90¢ a pound. How many pounds of the $1.50 chocolate were used to make the mixture?
If x represents the pounds of $1.50 chocolates used, then which of the following represents the pounds of 90¢ chocolates used?
x
30 - x
30
Answer:
10 pounds of the $1.50 chocolate were used.
30 - x represents the number of pounds of the 0.90 chocolate used.
Step-by-step explanation:
30 * 1.10 = 1.5x + 0.9 (30 - x)
33 = 1.5x + 27 - 0.9x
0.6x = 6
x = 10
Answer:
30 - x

A clothing store is having a sale in which all T-shirts are $10. The sales tax is 5%. If Dan buys n T-shirts during this sale, the total cost of his purchase will be 10n + 0.05(10n). Interpret the meaning of 0.05(10n) in this context
Answer:
Step-by-step explanation:
Cost of 1 T-shirt = $ 10
Sales tax for 1 T-shirt = 5% * 10 = 0.05 * 10
Cost of n T-shirt = $ 10n
Sales tax for 'n' T-shirts = 0.05 * (10n)
Sales tax on 'n' T-shirts = Sales tax for 1 T-shirt * (Cost of n T-shirt)
Answer:
the cost of the t shirt = 10 times the sale tax which is 5%

A school allots £2000 to spend on a trip to the theatre. Theatre tickets have a regular cost of £32 each and are on offer for 1 4 off. A train ticket for the day will cost £12 each. If 2 teachers and the maximum number of students attend, how much money will the school have left over?
Answer:
£20
Step-by-step explanation:
Given that:
Total amount alloted = 2000
Ticket cost = 32
Discount = 1/4 off
Hence, ticket price = 3/4 * 32 = 24
Train ticket cost = 12
Total cost per person = £(12 + 24) = £36
Hence, alloted amount / cost per person
= £2000 / £36
= 55.55
Total number that can attend = 2 teachers and 53 students
Change = £2000 - (£36*55)
= £20
Question- Solve for a
2a+b=x
Answer:
a = (x - b)/2
Step-by-step explanation:
2a + b = x
-b -b
2a = x - b
/2 /2
a = (x - b)/2
for ex:
x = 3
b = 2
a = ((3) - (2))/2 = 0.5
a = 0.5
2a + b = x
2(0.5) + 2 = 3
