Alicia uses 3/4 gallon of paint to paint her room. Becca uses for 4/5 gallon more than Alicia to paint her room. How many gallon
Maurinko [17]

Answer:

23/10 gallons

Step-by-step explanation:

Alicia uses 3/4 gallon of paint to paint her room.

Alicia use = 3/4 gallon of paint

Becca uses for 4/5 gallon more than Alicia to paint her room.

Becca uses = Alicia (3/4 gallons ) + 4/5

Becca uses = \frac{3}{4} + \frac{4}{5}

Total paint used together = Aliccia used + Becca used

\frac{3}{4}+\frac{3}{4} + \frac{4}{5}

Add like fractions 3/4 + 3/4 becomes 6/4

\frac{6}{4} + \frac{4}{5}

Make the denominators same

\frac{6*5}{4*5} + \frac{4*4}{5*4}

\frac{30}{20} + \frac{16}{20}

\frac{46}{20}

Divide top and bottom by 2

\frac{23}{10} gallons

Line segment AB is reflected across the y–axis to form line segment CD. Then, line segment CD is rotated 90° clockwise about the
Maksim231197 [3]

Answer:

The coordinates of EF are E(5,-4) and F(1,-4).

The line segment EF is in QIV

Step-by-step explanation:

The line segment AB has vertices at: A(-4,5) and B(-4,1).

We apply the rule (x,y)\to (-x,y) to reflect AB in the y-axis to obtain CD.

\implies A(-4,5)\to C(4,5)

\implies B(-4,1)\to D(4,1)

We apply the rule (x,y)\to (y,-x) to rotate CD 90 degrees clockwise about the origin to obtain EF.

\implies C(4,5)\to E(5,-4)

\implies D(4,1)\to F(1,-4)

The coordinates of EF are E(5,-4) and F(1,-4).

According to a student survey, 16 students liked history, 19 liked English, 18 liked math, 8 liked math and English, 5 liked his
Bogdan [553]
When building a Venn Diagram, I always start from the area with the most overlap to the areas of least overlap. Once you have placed the 3 in the middle, you have counted those people, and therefore you must subtract them from the other surveys. Example: since there are 3 people that like all three subjects, now only have 5 students that like just math and English instead of 8. 

Therefore:
A) 36 Students were in the survey
*Add all the numbers within the Venn diagram up. Overlapping doesn't matter because no one is double counted. 

B) 6 People liked only Math
*Can't touch any other circle but Math

C) 20 Students liked English and math, but not history
*You add 9+5+6, since these bubbles are not overlapping with history. 

I Hope this helps and let me know if you have any further questions!

Only need A for number 1 and B for number 2
lisabon 2012 [21]
Well 1A is wrong as 13+4=17 and 11+7=18 and 2B is also wrong as 6 squared is 36 and 4 squared is 16,36+16=52 6+4=10 10 squared is 100 on (6+4) squared you would do the addition as there is BIDMAS brackets indices division multiplication addition and subtraction
