Answer:
The required integers are x=3 and y= -9
Step-by-step explanation:
Let one the integers be x and y
An integer is 15 more than 2 times another: x=15+2y
product of the two integers is -27: x*y=27
[tex]x=15+2y ---eq(1)\\x*y=-27----eq(2)[/tex]
Solving both equations to find values of x and y
Putting value of x from equation 1 in equation 2
[tex](15+2y)*y=-27\\15y+2y^2=-27\\Rearranging:\\2y^2+15y-27=0[/tex]
This can be solved using quadratic formula:
[tex]$y=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
Putting values and finding factors
[tex]$y=\frac{-(15)\pm\sqrt{(15)^2-4(2)(-27)}}{2(2)}$\\$y=\frac{-(15)\pm\sqrt{225+216}}{4}$\\$y=\frac{-(15)\pm\sqrt{441}}{4}$\\$y=\frac{-(15)\pm21}{4}$\\$y=\frac{-(15)+21}{4} \ or \ y=\frac{-(15)-21}{4}$\\$y=\frac{6}{4} \ or \ y=\frac{-36}{4}$\\$y=\frac{3}{2} \ or \ y=-9$[/tex]
Since y is integer so, we consider only y= -9
The value of x will be:
[tex]x*y=-27\\x*(-9)=-27\\x=\frac{-27}{-9} \\x=3[/tex]
So, the value of x is x=3
The required integers are x=3 and y= -9
An exam has two probability problems, 1 and 2. If 37% of the students solved problem 1 and 12% of the students solved both problems 1 and 2, what is the percent of students who solved problem 2 given that they solved problem 1
Answer:
63%
Step-by-step explanation:
37% did not solve problem 2
100% - 37% = 63%

Answer:
2^52
Step-by-step explanation:
Assuming that we have to just figure out another way of writing it, we can use one of the laws of exponents which is powers of powers so we multiply 13 and 4 and we get 2^52.
2^52 is such a big number I'm not even going to solve it because I doubt that's what they want from you.

Answer:
52 degrees (which agrees with the last answer option).
Step-by-step explanation:
You need to subtract from 90 degrees (the measure of the larger angle < DCF) the measure of angle <ECF (which is 38) to find the measure of the angle that is left <DCE:
< DCE = 90 - 38 = 52 degrees (which agrees with the last answer option).
A painter uses 1.2 liters of the paint to cover 1m2 of the wall.
How many square meters he can cover with 6.6 liters of paint?
12)/1.2=120/12=10m^2
4.8/1.2=48/12=4m^2
6.6/1.2=66/12=11/2=5.5m^2
this is another way you can do it
1. 12/1.2 times as much paint, so 12/1.2 times as much area.
2. 6.6/1.2 times as much paint, so 6.6/1.2 times as much area.
3. 4.8/1.2 times as much paint, so 4.8/1.2 times as much area.

Rectangle A and rectangle B are similar.
Rectangle A has a length of 6.2 centimeters
and a width of 5.6 centimeters. Rectangle B
has a length of 21.7 centimeters. What is the
perimeter of rectangle B?
Answer:
82.6 cm
Step-by-step explanation:
First, we make a proportion:
6.2(length A) / 5.6(width A) = 21.7(length B) / x(width B)
Cross multiply: 6.2 * x =( 21.7) * (5.6)
Divide both sides by 6.2: x = 19.6
So the width of rectangle B is 19.6. Now lets find the perimeter
19.6 + 19.6 + 21.7 + 21.7 = 82.6 cm

Answer:
1) Product of 2 x 3/5 is 6/5 or 1 and 1/5.
2) 20/9 or 2 and 2/9
3) 15/8 or 1 and 7/8
4) 15/6 or 2 and 3/6 or 2 and 1/2
5) 6/4 or 1 and 2/4 or 1 and 1/2
Step-by-step explanation:
You multiply the whole number by the numerator (top number) and then divide the result by the denominator(bottom number). Afterward, simplify the fraction if you can, for example, 6/9. Both the numerator and denominator can be divided by 3. Therefore, the answer to that example is 2/3.

the perimeter of a rectangle pool is 56 meters the length of the pool is 16 Meters what is the area of the pool
The area of the rectangle pool is 192 square feet
Answer:
160meters^2
Step-by-step explanation:
You know the perimeter is 56, and there are four sides. Two of the sides are the same (16 and 16), and the other two sides are the same. Add 16 to 16 and then subtract it from 56 to get the remaining two sides. 56 - 32 = 20. 20 needs to be split in half to find the other two sides. Now you know the sides are 16, 16, 10, and 10. Multiply Length by width (16 times 10) and you get 160 meters (squared) as the total area.

Charlie bought 2 3/4 pounds of pears for $.76 per pound and 2 3/4 pounds of grapes for $1.40 per pound how much money in dollars and cents did Charlie pay for the pears and grapes
Answer:
5.94
Step-by-step explanation:
Multiply 2.75 by $0.76 to get $2.09
Multiply 2.75 by $1.40 to get $3.85
Add $3.85 and $2.09 to get $5.94
The money in dollars is 5.94 and cents 594 did Charlie pay for the pears and grapes
We have given that,
2.75 pound of pears cost $ 0.76
Therefore,
2.75×0.76=2.09.....(1)
$2.75 pound of grapes cost $1.40
Then the cost of grapes is
2.75× 1.40=$3.85..........(2)
add value of equation 1 and equation 2 we will get
2.09+3.85=$5.94
So the charlie has to pay 5.94 in dollar
Next we have to find in cents
What is the value of 1 dollar in cents?
[tex]$1=100[/tex]cent
multiply both side by 5.94
[tex]$1* 5.94=100 * 5.94[/tex]
[tex]5.94 dollars=594 cents[/tex]
Therefore,
The money in dollars is 5.94 and cents 594 did Charlie pay for the pears and grapes.

2.)The percentage of students who chose cats as their favorite pet was 60%.
3.)There were more students surveyed in grade 3 than in grade 4.
4.)Birds were the type of pet chosen least often by the students in grade 4.
5.)Dogs were the type of pet chosen most often by the students at the elementary school.
Answer:
5.)Dogs were the type of pet chosen most often by the students at the elementary school.
Step-by-step explanation:
Dogs have the most out of every pet at 110
From the two-way table, the correct option is:
5.) Dogs were the type of pet chosen most often by the students at the elementary school.
Statement 1:
105 students in grade 3.Of those, 60 prefer dogs.The percentage is:[tex]P = \frac{60}{105} \times 100\% = 57\%[/tex]
It is not 55%, thus, statement 1 is false.Statement 2:
Total of 215 students.Of those, 60 prefer cats.The percentage is:[tex]P = \frac{60}{215} \times 100\% = 29\%[/tex]
It is not 60%, thus, statement 2 is false.Grade 3 had 105 students, grade 4 had 110 students, thus statement 3 is false.The type of pet chosen the least often by grade 4 students was other, thus statement 4 is false.Cats were chosen 60 times, dogs 110, birds 20 and other 25, thus dogs were chosen the most often, and statement 5 is correct.A similar problem is given at https://brainly.com/question/23719681
