In a drill, Mark gives Fred a 45 meter head start. After t seconds, Fred is a distance 5t +45 from the starting line andMark is a distance of 6t from the starting line. How far ahead of Mark is Fred after t seconds?
Answer: After t seconds, Fred is far away from Mark by (45-t).
Step-by-step explanation:
Given: Mark gives Fred a 45meter head start.
After t seconds, the distance of Fred from the starting point = 5t+45
The distance of Mark from the starting point = 6t
Now, Distance between Fred and Mark after t seconds = Location of Fred - Location of Mark
= (5t+45)-6t
= 5t+45-6t
= 45-t
Hence, After t seconds, Fred is far away from Mark by (45-t).

Find the measure of angle b
Answer:
26˚
Step-by-step explanation:
Since there is already two angles (The square in the corner shows that the angle is 90˚)
So subtract 90˚ with 64˚ which is 26˚
Answer:
this whole angle is equal to 90°
so the value of angle b = 90°-64°
so the value of b= 26.

Answer:
it is 35 degrees
Step-by-step explanation:
I am sure of it
The measure of the angle indicated is 35 degrees
ProtractorProtractor is a mathematical measuring instrument use to measure angles. Therefore, A protractor is in the shape of a semi circle.
A protractor has degrees marked clockwise from 0° to 180° in the outer scale and anti-clockwise from 0° to 180° in the inner scale.
From the blue lines indicated above the angle was marked at 0 degrees and ended in 35 degrees,.
Therefore, the angle measure of the angle is 35°

1. Add the correct symbols (+, -, x, ) to make this statement true: 2_22_20_21 = 46.2
The sum of two numbers is 30 and their difference is 4. Find the numbers
Answer:
17 and 13
Step-by-step explanation:
So you can set up an equation:
let x be the greater number
this means that the smaller number would be 4 less than x, because their difference is 4, so x - 4.
The sum is 30, so x + (x - 4) = 30
Then, solve:
x + (x - 4) = 30
x + x - 4 = 30
combine like terms
2x - 4 = 30
add 4 to both sides
2x = 34
divide both sides by 2
x= 17
Now you know the greater number is 17. Since they have a difference of 4, you can do 17 - 4 = 13 to get the smaller number.
The numbers are 17 and 13
Four positive whole numbers add up to 96
One of the numbers is a multiple of 19
The other three numbers are equal.
What are the four
numbers?
Multiple of 19
goes here
Other four Positive whole number is 13
What is whole number?The whole numbers are the numbers without fractions and it is a collection of positive integers and zero. It is represented by the symbol “W” and the set of numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}. Zero as a whole represents nothing or a null value.
According to the question
First, we consider that if we add together three equal numbers, the result must be a multiple of three. For example, 7 + 7 + 7 = 21, or 11 + 11 + 11 = 33.
Algebraically, we'd say that n + n + n = 3n.
So this means that if we subtract the first number (the one that's a multiple of 19) from 97, we will have a result that is a multiple of 3.
What could the first number be? 19, 38, 57 or 76 . Any other value is larger than the sum of 7, which is not possible if all the integers are non-negative.
Based on this, we can find all possible sums of the other four numbers, by subtracting each of the numbers above from 96:
96 - 19 = 77
96 - 38 = 58
96 - 57 = 39
96 - 76 = 20
Remember what I said earlier? The other four numbers must add to a multiple of 3. The only one of those sums above that is a multiple of 3 is 39. Therefore, we conclude that the first number is 57, and the other four numbers are each 13 (because 39 / 3 = 13).
Hence, other four number is 13

mr iniguez can bike 157 miles in 5 hours . How many miles can he bike 1 hour?
Answer: its 31.4 i think cuz if you divide 157 and 5 you get 31.4 in an hour
Step-by-step explanation:
I divided
Answer:
If he bikes 157 miles in 5 hours and we need to know hhwo many miles he can bike in 1 hour, we need to divide
157/5=31.4
Step-by-step explanation:
157 divided by 5
5 fits in 15 3 times
5x3=15
15-15=0
we bring down the 7 and 5 only fits in 7 one time
5x1 is 5 so 7-5 is 2
we add a decimal after 157 and drop it down to creat 20
5x4 is 20 so the answer is 31.4
