What units are you going by?
Step-by-step explanation:
After raining for 3/4 of an hour, a rain gauge is 2/5 filled. If it continues to rain at that rate for 15 more minutes, what fraction of the rain gauge will be filled?
To help answer this question, Diego wrote the division equation 3/4 ÷ 2/5 = ?. Explain why this equation does not represent the situation.
Number of minutes in 3/4 of an hour is :
n = 3/4 × 60 = 45 minutes.
Now, If it continues to rain at that rate for 15 more minutes :
So, time taken = 45 + 15 min = 1 hour.
Let, rain gauge is filled x fraction in 1 hour.
So,
[tex]\dfrac{3}{4}x = \dfrac{2}{5}\times 1\\\\x = \dfrac{8}{15}[/tex]
Hence, this is the required solution.

Answer:
It is e = 3
Step-by-step explanation:
It is e = 3 and not e = -3 because 44e - 41 e = 3e, then you'd subtract 30 from both sides to get the 3e equal to something which is 9. then dividing both sides by 3 would give you e = 3

Step-by-step explanation:
Write an equation of the line that is perpendicular to 2x +4y = 6 and passes through the point (6,4)
Answer:
B
Step-by-step explanation:
let equation be y = mx + b.
2x + 4y = 6
1/2x + y = 3/2
y = -1/2x + 3/2
since perpendicular, their gradients produced equals neg 1.
so,
m = -1/(-1/2) = 2
sub (6, 4):
4 = 2(6) + b
b = -8
therefore, eqn is y = 2x - 8

Please helppp it’s confusing!!!
Answer:
First you'd look at PEMDAS (parenthesis, exponent, multiplication, division, addition, and subtraction( you'd look at them in this order to solve the equation properly.))
So there is a parenthesis, that would be the 3(2^0). ignore the three, because you're focusing on the parenthesis. Any number other than zero with an exponent of zero will always be one. leaving you with 3(1).
So by now you should know (depending on your level of mathematics, That a number beside a single number in a parenthesis is multiplication. so 3 times 1.
Knowing that any number, other than zero, multiplied by 1 is the number itself, The answer is 3
In short, 3(2^0) = 3

A collection of nickel and quarters is worth $4.65. There are 3 more nickels than quarters. How many coins are there in the collection?
Answer:
There are 15 quarters and 18 nickles
Step-by-step explanation:
The equations derived from this word problem are
5n + 25q = 465
and
3 + q = n
Fill (3 + q) into n in the first equation then solve. You get q = 15.
Then plug 15 into second equation (cause it's easier).
You get n = 18

Mia has some beans that weigh 91 grams and some rice that weigh 58 grams how much more do the beans weigh then the rice?
Answer:33
Step-by-step explanation: Subtract 91 by 58
After that it gives you 33 so the beans weigh 33 more g's than the rice
Answer:
The beans weigh 33 grams more than the rice.
Step-by-step explanation:
To solve this, find the difference between the two numbers by subtracting the smaller number from the larger one.
91-58=33

Answer:
(d) see below
Step-by-step explanation:
Since each grid square is 1/4 unit. the coordinates in terms of grid squares are ...
A(0.50, -1.25) ⇒ (0.50/.25, -1.25/.25) = (2, -5) . . . grid squares
Point A is located 2 squares right and 5 squares down on the grid. This matches choice D.
Answer:
I believe it's D

Answer: ∠1 = 77; ∠3 = 41; ∠5 = 41; ∠6 = 92; ∠9 = 103; ∠12 = 47; ∠14 = 103; ∠17 = 41
because of 2 parallel lines
=> ∠1 = ∠10 = 77°
∠7 = ∠12 = 47°
∠16 = ∠7 + ∠6 = 139° ⇒ ∠6 = 139° - ∠7 = 92°
have: ∠7 + ∠6 + ∠5 = 180° ⇒ ∠5 = 180° - (∠7 + ∠6) = 180° - 139° = 41°
∠10 + ∠14 = 180° ⇔ ∠14 = 180° - ∠10 = 103°
∠14 = ∠9 = 103°
∠3 = ∠5 = ∠17 = 41°
