A photographer takes a picture of a train travelling at the speed of 40m/s.If the camera takes 0.01sec to take picture,how far did the train travel in this time?
Answer: 0.4m
Step-by-step explanation:
From the question, photographer takes a picture of a train travelling at the speed of 40m/s and the camera takes 0.01sec to take picture. We want to know the distance that the train travelled in this time.
Distance = speed × time
Distance = 40m/s × 0.01s
= 0.4m

Two parallel lines are crossed by a transversal. Horizontal and parallel lines p and q are cut by transversal m. At the intersection of lines p and m, the bottom left angle is b degrees. At the intersection of lines q and m, the top right angle is 128 degrees. What is the value of b?
Answer:
128
Step-by-step explanation:
Answer:
I think its C: 102
Step-by-step explanation:
78 + x = 180
180-78 = 102
Find the value of x.
Answer:
98 °
Step-by-step explanation:
We know that the sum of the angles in a triangle is 180. We also know that angle DAB is 122°, meaning that angle CAB is 180-122, which is 58°. We also know that angle CBA is 24 degrees. Therefore, angle x is just 180-(58+24), which is 98

Answer:
$150
Step-by-step explanation:
5+10+30+100+5=150
10
Step-by-step explanation:
The way I look at it I think 10.00 cause it says I had in the beginning k and it says what people gave me and at the end it says what I had as well so I had 5.00 in the beginning and then I had another 5.00 so that makes it 10.00 in all realatly really let me know if I'm right as it's the only thing that makes since with it all..... lol so the answer is 10.00.... so if it would of said how much do I have all together then it would be what my granddaughter said but it didn't. It's a tricky question here and a good one to get people thinking on it haaa haaa

There were more dragons than knights in the battle. In fact, the ratio of dragons to knights was 5 to 4. If there were 60 knights, how many dragons were there?
Answer:
75 Dragons
Step-by-step explanation:
We know that the ratio is 5 dragons and 4 knights.
Now, there are 60 knights, meaning the original number of knights (4), was multiplied by 15. So, if one side is multiplied by 15, the other side must follow the same rule. So, 15 x 5 = 75.
There are 75 Dragons.
Answer:
75
Step-by-step explanation:
thats a lot of flipping dragons, you better hope they are the size of a dog or youre flipping dead

Toby goes on holiday to Geneva, Switzerland. In Geneva, Toby sees a watch costing 193.75 CHF (Swiss Francs). In Manchester, an identical watch costs £145. Given that £1=1.55CHF a) In which city is the watch cheaper. b) By how much is it cheaper (in £) i need help on part b , pleeeeaseeee help;(
Answer:
The watch is cheaper in Geneva, Switzerland by a value of £20
Step-by-step explanation:
To get the city in which the watch is cheaper, what we need to do is to express the price of the watch in the same currency.
Since pounds is also used in the b part of the question, it would be easier working with it.
In Geneva, the price of the watch is 193.75 CHF
from our conversion formula;
£1 = 1.55 CHF
£x = 193.75 CHF
We cross multiply to get the value of x
(193.75 * 1)/1.55
= 193.75/1.55 = £125
We can see that the watch costs less in Geneva and higher in Manchester
By how much is it cheaper?
We can calculate this by subtracting the value in Geneva from the value in Manchester
That would be 145-125 = £20 cheaper

Olivia has $143 in the bank. She withdraws $40. Then she deposits $92. Write an addition expression to represent the situation.Then find the sum.
Answer:
The addition expression to represent the situation is $143 + ( - $40 ) + ( $92)
Sum is $195
Step-by-step explanation:
Given: Olivia has $143 in the bank. She withdraws $40. Then she deposits $92
To find: addition expression to represent the given situation. Also, to find the sum
Solution:
Amount in the bank = $143
Amount withdrawn from the bank is denoted by the minus sign
So, amount withdrawn from the bank = - $40
Amount deposited in the bank is denoted by the plus sign
So, amount deposited in the bank = +$92
Therefore,
the addition expression to represent the situation is $143 + ( - $40 ) + ( $92 )
Also,
$143 + ( - $40 ) + ( $92 ) = $143 - $40 + $92 = $195

Janice is traveling at a constant rate. She traveled 243 miles on 9 gallons of gas and 324 miles on 12 gallons of gas. How many miles can Janice travel on one gallon of gas?
Divide total miles driven by number of gallons of gas used.
243 miles / 9 gallons = 27 miles per gallon
324 miles / 12 gallons = 27 miles per gallon.
She can drive 27 miles on one gallon of gas.
A dining set is priced at $785. If the sales tax is 7 percent, what is the cost to purchase the dining set? Round to the nearest cent if necessary
Answer:
$839.95
Step-by-step explanation:
The dining set costs 785.
The sale tax is 7%
This means that the tax costs 7% of 785.
Sales tax: 785*0.07=54.95
Add to original price to find the total price.
54.95+785=839.95
The cost to purchase the dining set is $839.95
Answer:
835.95
Step-by-step explanation:
A candy company claims that 25% of the candies in its bags are colored green. Steve buys 32 bags of 32 candies, randomly selects one candy from each, and counts the number of green candies. If there are 7, 8, or 9 green candies, Steve will conclude that the company's claim is correct. What is the probability of Steve agreeing with the company's claim? Use Excel to find the probability.
Answer:
45.88%
Step-by-step explanation:
We have in this case a binomial distribution when p = 0.25, since the probability is 25%
. The formula that we will use in excel is BINOM.DIST, separated by commas we must put the value of x, n, p and also if it is true or false. We know that n equals 32.
In this case we need to know when x = 7, 8 and 9 and add this, and thus we will obtain the probability:
P (X = 7) + P (X = 8) + P (X = 9)
Excel formulas: = BINOM.DIST (7,32,0.25, FALSE) + BINOM.DIST (8,32,0.25, FALSE) + BINOM.DIST (9,32,0.25, FALSE)
P = 0.1546 + 0.1610 + 0.1431
P = 0.4588
Probability that steve agrees with the company's claim 45.88%
What is the value of (16^3/2)^1/2
Answer:
8
Step-by-step explanation:
(16^3/2)^1/2
We know that a^ b^c = a^(b*c)
16 ^(3/2*1/2)
16 ^3/4
Now rewriting 16 as 2^4
2^4^3/4
2 ^ (4*3/4)
2^3
8

Find the volume of a cone with a height of 9 cm and a base of 5 cm
Answer:
V=πr2h
3
Step-by-step explanation:
Answer:
15 cm³
Step-by-step explanation:
The formula for the volume of a cone is:
V = πr²h /3
where r is the radius and h is the height
Let's substitute the given values into this equation:
V = πr²h /3
(Remember that the base of a cone is a circle and the formula for the area of a circle is πr²)
V = πr²h /3
V = (5)(9/3)
Solve:
V = (5)(9/3)
V = (5)(3)
V = 15
Therefore, the volume of the cone is 15 cubic centimeters.

Please help meeeeeeee only answered this if you know geometry
Answer:
Step-by-step explanation:
AL is congruent to EK, and angle K is congruent to angle L. The only other congruency not marked but you know to be true is that, by the reflexive property, side AE is congruent to side AE. But that would give us a congruency statement SSA which is not actually a way to prove triangle congruency (you'll learn why if you take pre-calculus). So none of the choices work for what you're given.
