Answer:

I don't understand the instructions, but I'll answer the question in the picture.

The angle next to 52 is vertical to y, so, 90-52=y.

Thus, y=38

It takes 2 3/4 gallons of water to fill up 3 1/3 containers.How much water woud it take to fill 4 containers.

mafiozo [28]

Answer:

3.3 gallons

Step-by-step explanation:

(2 3/4)/x = (3 1/3)/4

(11/4)/x = (10/3)/4 (cross multiplication)

(11/4)*(4/1)=44/4=11

11/(10/3) = ( 11/1 ) * (3/10) = 33/10 = 3.3 gallons

The sides of a triangle are 7, 4, n. If n is an integer, state the largest and smallest possible values of n. smallest value- la

VLD [36.1K]

The smallest value it could be is 4 and the largest value it could be is 10.

The triangle inequality theorem states that any two sides of a triangle must have a sum greater than the third side. Given the two sides we have, 7 and 4, the sum would be 11; this would mean that the missing side could be no more than 10.

If we take the unknown side and the smallest one we're given, we would have the inequality
n+4>7

Subtracting 4 from both sides we would have n>3. That means it would have to be the next integer up, which would be 4.

Four speed skaters, Marco, Naim, Oliver, and Pedro, compete in a relay race where they all agree that Naim will be the last

allochka39001 [22]

Answer:

A = {MOPN, MPON, PMON, POMN}

Step-by-step explanation:

Everyone has already agreed that Naim would be the last skater, so we have to make sure that the result has 'N' in each last place. As we can see, they all have this.

Now, we also have to make sure Oliver <u>not</u> first, because although they're trying to decide, the problem asks for the <u>complement</u> in which "Oliver is the first skater in the race."

A complement is all the values that are NOT in the set, so it cannot be A = {OPMN, OMPN) or A = {MOPN,MPON, OPMN, POMN), because they both have at least one case where 'O' is first.

A complement is ALL other values of the set, so it cannot be A = {MOPN, PMON}, because that set only shows two possible values.

Therefore, A = {MOPN, MPON, PMON, POMN} is your answer.

Calculate the value of 3x + 4y when x = -6 and y = 5.

MArishka [77]

Answer:

x = -6

-18+4y=0 => 4y=18 =>y=18/4=9/2

Y=5

3x+20=0 => x=3x= -20=> x= -20/3
