* 10. You have 39 math and science problems for homework. You
have 15 more math problems than science problems. Use the
model to write a system of linear equations. How many problems
do you have in each subject?

Answers

Answer:

Science problems= 12

Math problems= 27

Step-by-step explanation:

x= math problems for solving

y= science problems for solving

x+y=39

y=x-15

Using substitution method:

x+(x-15)=39

2x-15=39

2x=39+15

x=(39+15)/2

x=27

Having "x" lets find out "y" value.

x+y=39

27+y=39

y=39-27

y=12

Answer:

2.1 ft³

Step-by-step explanation:

Put the given radius and height into the volume formula and do the arithmetic.

V = 1/3πr²h

V = 1/3(3.14159)(1 ft)²(2 ft) ≈ 2.094 ft³

Rounded to tenths, this is 2.1 cubic feet.

The picture cuts off your rounding requirements. If it is hundredths, you need to use 2.09 ft³. If it is thousandths, your answer will depend on the value of pi you are asked to use.

Answer:

A: 8 ft²

B: draw diagonal AC; 4 ft²

Step-by-step explanation:

Part A: The area is given by the formula ...

A = bh . . . . . . . the product of base and height dimensions

A = (9 ft)(8/9 ft) = 8 ft² . . . . area of the parallelogram

Part B:

Either diagonal (AC or BD) will divide the parallelogram into two congruent triangles, each with the same base and height as the parallelogram. It is no surprise, then, that the area of either of those triangles is ...

A = 1/2bh

A = 1/2(9 ft)(8/9 ft) = 4 ft² . . . . . . area of triangular half of parallelogram

AC divides the figure into congruent acute triangles; BD divides it into congruent obtuse triangles.

[tex]y=-\frac{1}{5} x-1[/tex]

Step-by-step explanation:

Hi! Welcome to brainly!

So slope intercept form - y = mx + b

where m = slope and b = y intercept

First lets find the y intercept

The y intercept is at (0,-1)

B would equal the y value of the y intercept so b = -1

now lets find the slope

To do so we can pick 2 points on the line and use the slope formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

the points can vary but i chose the points (5,-2) and (10,-3)

having found the points we plug them into the formula

[tex]m = \frac{-3-(-2)}{10-5} \\-3-(-2)=-1\\10-5=5\\m=-\frac{1}{5}[/tex]

now that we have found all of the information we plug the values into the equation and get that the answer is

[tex]y=-\frac{1}{5} x-1[/tex]

b. x = -+1
c. There are two possible solutions.
d. x = -1
e. None of the remaining possibilities is correct.

Answers

Answer:

Step-by-step explanation:

hello :

the numbers a1 , a2 ,a3

form three consecutive members of an arithmetic sequence means : 2a2 = a1+,a3

2 In(x + 3) = In(x + 2)+In(4x + 8)....(*)

now solve this equation use this note :

ln a^n = alna and : lna+lnb =lnab lna =lnb means : a=b ...a , b positif numbers

(*) equivaut : In(x + 3)² = In(x + 2)(4x + 8) and : x + 2 ,x + 3 , 4x + 8

are positifs numbers

(x + 3)² = (x + 2)(4x + 8)

x²+6x+9 = 4x²+16x+16

3x²+10x+7 =0

delta =10²-4(3)(7) 100 -84 = 4²

x1 = (-10-4)/6 = -7/3 reused

x 2 = (-10+4)/6 = -1 reused

conclusion : a. Such x does not exist.

each group of students receives a bag that has 4 red cubes, 9 green cubes and 7 blue cubes if if each group makes 200 pulls and replaces the cube after each pull, how many times would you expect them to draw a green cube?

Answers

There are 20 cubes total. Green cubes make up 9/20 of the cubes. So if you make 20 pulls with replacement you would expect to get 9 green cubes. Therefore, you would expect to pull a green cube 90 times after pulling 200 cubes.
