Answer:
a₃₁
Step-by-step explanation:
The terms have a common difference between consecutive terms, that is
d = 84 - 87 = 81 - 84 = - 3
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 87 and d = - 3 , then
[tex]a_{n}[/tex] = 87 - 3(n - 1) = 87 - 3n + 3 = 90 - 3n
To find when [tex]a_{n}[/tex] < 0 , solve
90 - 3n < 0 ( subtract 90 from both sides )
- 3n < - 90
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity, then
n > 30
Thus the 31st term will be the first negative term

Find the volume of the cylinder find volume of a cylinder with the same radius and double the height what is the volume of the cylinder
Answer:
1004.8^3
Step-by-step explanation:
to find the volume you must first get the area of the base
3.14 x 8 squared or 8^2 which will equal 200.96
then you multiply the base times height
200.96^2 x 5 = 1004.8 cubed or 1004.8^3
also be careful you don't multiply 200.96 twice because it is squared (;
D Melissa takes the 10 30 from Christchurch. How long does she wait in Wellington? Hour minutes
Answer:
1:45 hours
Step-by-step explanation:
Given
See attachment for missing part of the question
Required
How long she waits in Wellington
From the question:
She takes the 10 30 from Christchurch
So:
[tex]Christchurch\ Depart = 10\ 30[/tex]
This implies that:
She has to wait until Wellington arrives at 11 15
So:
[tex]Wellington\ Arrives= 11\ 15[/tex]
So, the wait time is:
[tex]Wait\ time = Wellington\ Arrives - Christchurch\ depart[/tex]
[tex]Wait\ time = 11: 15 - 10: 30[/tex]
[tex]Wait\ time = 1:45\ hr[/tex]

The total distance in centimeters a toy robot moves varies directly with the time in seconds. The toy robot moves a total distance of 140 centimeters in 35 seconds. What is the time in seconds the toy robot moves when the total distance is 70 centimeters?
Answer:
17.5 seconds
Step-by-step explanation:
140 cm/35 sec (find unit rate)
4 cm/ 1 second
[tex]\frac{4}{1} = \frac{70}{x}[/tex] (divide 70 by 4)
70/4=17.5
[tex]\frac{4}{1} = \frac{70}{17.5}[/tex]

Plz help and show me how to solve these questions
since -15/16 is a negative number, we can add both sides by 15/16 or subtract both sides by -15/16. Either way works.
p = 1/8 + 15/16
Use common denominator, which is 16:
p = 1(2)/8(2) + 15/16
p = 2/16 + 15/16
p = 17/16
17/16 is an improper fraction. If you want to use a mixed number for your answer, then:
17/16 becomes 1 1/16 (one and one-sixteenth, with 1 being a whole number and 1/16 being a fraction)
Answer: 17/16 or 1 1/16What is the missing length?

Find the measure of the angles and arcs
here have a good day
Answer:
multiple both of them and you get your answer
M∠QPS=88 ∘ m, angle, Q, P, S, equals, 88, degrees \qquad m \angle RPS = 5x + 34^\circm∠RPS=5x+34 ∘ m, angle, R, P, S, equals, 5, x, plus, 34, degrees \qquad m \angle QPR = 8x + 15^\circm∠QPR=8x+15 ∘
The correct question is:
[tex]\angle QPS=88[/tex]
[tex]\angle RPS=5x+34[/tex]
[tex]\angle QPR=8x+15[/tex].
Find ∠QPR.
Answer:
[tex]\angle QPR = 39[/tex]
Step-by-step explanation:
From the attached figure:
[tex]QPS = QPR + RPS[/tex]
This gives:
[tex]88 = 8x + 15 + 5x + 34[/tex]
Collect like terms
[tex]88 - 15 - 34 = 8x + 5x[/tex]
[tex]39 = 13x[/tex]
Divide both sides by 13
[tex]3 = x[/tex]
[tex]x =3[/tex]
Substitute [tex]x =3[/tex] in [tex]\angle QPR=8x+15[/tex]
[tex]\angle QPR = 8 * 3 + 15[/tex]
[tex]\angle QPR = 24 + 15[/tex]
[tex]\angle QPR = 39[/tex]

= 6 - 3√3 + 2√3 - 3
= 3 - 3√3 + 2√3
= 3 - √3 (3 - 2)
= 3 - √3
= 3 - 1.732 ...... (√3 = 1.732)

Step-by-step explanation:
A jeweler has several boxes of earrings to ship to a store. Each box is a cube with a side length of 5 centimeters. The jeweler packs the boxes in a shipping container. The filled container has 4 layers, where each layer contains 7 rows and 10 columns of boxes. What is the volume of the shipping container?
Answer: [tex]35,000\ cm^3[/tex]
Step-by-step explanation:
Given
The earring box has a volume of [tex]a=5\ cm[/tex]
It is packed and loaded in the container which has 4 layers and each layer has 7 rows and 10 columns
We can say that each layer can hold [tex]7\times 10=70\ \text{boxes}[/tex]
The volume of each earring box is
[tex]V_o=a^3=5^3\\V_o=125\ cm^3[/tex]
Four layers can hold [tex]4\times 70=280\ \text{boxes}[/tex]
the container can hold 280 boxes
[tex]\therefore \text{Volume of container is}\ V=280V_o\\\Rightarrow V=280\times 125=35000\ cm^3[/tex]
