Answer:
Solution given:
[tex]25x = 100[/tex]
[tex]x = \frac{100}{25}[/tex]
[tex]x = 4[/tex]
x=4 is a required answer.
Let's check
25x=100x=100/25x=4/1x=4x is 4
A ball and a bat cost £90 in total. Three balls and two bats cost £210 in total. How much
does a bat cost?
Submit Answer
Answer: 60
Step-by-step explanation:
ball =x
bat = y
x + y = 90
and
equation II is
3 x + 2 y =210
By multiplying by 3 to equation I both sides
we get equation III as
3( x + y) = 3 ( 90 )
3x + 3y =270 III
subtract II and III
we get 3x+3y=270
- 3x+2y=210
--------------------------
0+y= 60
y =60
cost of bat is y ie = 60
and cost of ball ,is
let put value of y in equation I
x+60=90
x=90-60
x=30
cost of ball is 30

what do you observe with the wavelength and frequency of the different colors?
what did you observe with the product of wavelength and frequency for each color? what is the significance of this value?
what can you say about the speed of the different colors?
Answer:
The responses to the given question can be defined as follows:
Step-by-step explanation:
Its color palette depends on how much radiation reaches the eyes or the intensity of it. If indeed the duration of a wave is less than 400 nm, it is called UV and much more than 750 nm simple pleasures light it is (IV). The shorter wavelength implies a much more frequent spectrum and lower frequencies are the longer wavelengths.
The shorter the distance, the higher it's indeed. Since the red duration has been longer, the intensity is low. The purple has a smaller range and a high frequency, on the other side. The wavelengths are shorter as well as the frequencies are lower than the red, and it will differ even as violet goes, Remember that even more power is provided with the longer the duration of color. That wave/frequency color rises and is longer the purple color is becoming the lowest color.

Step-by-step explanation:
If you were to pick two marbles from the pile, there would be 30 different possible combinations. Out of the 30 possible combinations, 6 of them meet the requirement of green marble on the first pick and red marble on the second pick. The fraction that represents the situation would be [tex]\frac{6}{30}[/tex] or [tex]\frac{1}{5}[/tex], which would be equal to 20%, so that is the correct answer.

3. Add the thousandths and hundredths with 0
4. Add 3 in the tenths place
5. Add up 9 and 5 to make 14
*IF YOU DID THE STEPS RIGHT, THEN YOU SHOULD HAVE 14.379 AS YOUR ANSWER*
Answer:
9.079
+5.300
_______
14.379
Step-by-step explanation:
Just line the decimals up and add zeros for 5.3 to 5.300 because you can't do 9.079
+5.3 because your decimal will be in the wrong spot and your answer will come out wrong

Ayoub is driving to France for his holiday.
He will drive a total distance of 300 miles. Ayoub sets off at 07:15.
It takes him 2.5 hours to travel the first 125 miles.
Use this information to estimate the time Ayoub will arrive.
Answer:
10:30 hours
Step-by-step explanation:
Total distance=300 Miles, Start Time=07:15
Distance travelled so far is 125 miles for 2.5 hours
First we need to calculate Ayoub's speed as follows
Speed=Distance/Time
=125miles/2.5hour
=50 miles/hr
The calculate the remaining distance
=300-125
=175 Miles
Assuming that Ayoub Travels in the same speed at the first 300 miles, the time he will use to cover the remaining 175 miles is
Time=Distance/speed
Substituting the values
Time=175/50
=3.5 hours
The time he will arrive at Paris is
07:15+03:30
=10:30 hours

Question 2
First calculate the time taken to travel from woodpine to Westray
Time=Distance/ Speed
=32.5/65
=0.5 hours or 30 minutes
Next we calculate the average speed
Average speed is calculated by taking the total distance divided by total time taken
Total distance =32.5+100
=132.5KM
Total time=2+0.5
Average speed=132.5/2.5
=53km/

A
I WILL GIVE 30 POINTS!!!!!!
Answer:
Option D would be the correct answer:
Step-by-step explanation:
=> If we 15 is the why intercept, then it means when x = 0, y = 15. Now if the slope is 12.5x, it means that the graph is increasing by 12.5 units each time. This means if we say 15 + 12.5 + 12.5 (since we are given an x value for y = 2) we would get 40.00. And that we get, hence option D is the correct answer.
Hope this helps!
