Answer: 31 cups of sugar

Step-by-step explanation:

1 cup x 31 = 31 cups

Answer:

31

Step-by-step explanation:

1 x 31 = 31

Answer:

21

Step-by-step explanation:

Put them equal to eachother

(10x-29)=(8x+3)

2x=42

x=21

Given:

The given polar equation is:

[tex]r=8\cos\theta[/tex]

To find:

The rectangular form of the given polar equation.

Solution:

We know that,

[tex]r^2=x^2+y^2[/tex]

[tex]x=r\cos \theta[/tex]

We have,

[tex]r=8\cos\theta[/tex]

Multiply both sides by r.

[tex]r^2=8r\cos\theta[/tex]

[tex]x^2+y^2=8x[/tex]

Therefore, the correct option is D.

Brainliest please

x is equals to 4 and y is equal to 1

Step-by-step explanation:

3x+3y=9

x-3y=7

elimination method has to do with eliminating one variable from the question to eliminate y we have to add the equations together which is 4x=16

X=4

substitute x is equal to 4 into any equation of your choice let's use equation 1

E

3(4)+3y=9

12+3y=9

12-9=3y

3=3y

divide both sides by 3 therefore y is equal to 1.

Answer:

a<-4

Step-by-step explanation:

To solve this, you have to isolate a. This means you will have to add 5 to both sides. This will make the equation -2a>8. Divide both sides by 2 to get -a>4. Divide each side by -1 to get a>-4. Because you have to flip the sign when you divide by a negative number, you have to change it into a<-4.

Answer:

The answer is a triangle.

Answer:

Step-by-step explanation:

Given the expression √-36

This can also be written as;

√36 = √36 * √-1

Since i² = -1

√-1 = i

Substitute into the resuting expression

√-36 = √36 * i

√-36 = 6i

Hence the required answer is 6i

Answer: The answer is i sqrt 36  and  6i

Step-by-step explanation: I just took the test, so yea. :)

Answer:

$7.2 A.t a wholesale

Step-by-step explanation:

80%of $36

The mathematical order is :

80÷100×36

80÷100×36=$28.8

When we have found the 80% that is added

We subtract it from the retail price.

$36-$28=$7.2

At the end we are left with our wholesale prices.

Answer:

x = 74

Step-by-step explanation:

One of the properties of a parallelogram is that opposite angles are congruent. This means that the angle with a measure of (74) degrees and (x) degrees are the same, thus the following conclusion can be drawn,

x = 74

Answer:

12 11/35

Step-by-step explanation:

Given Data

First term= 15 3/5

To simple fracrion= 78/5

Second term= 3 2/7

To simple fracrion= 23/7

Hence the operation goes thus

= 78/5- 23/7

LCM = 35

=546-115/35

=431/35

=12 11/35

Answer:

[tex] 12 \frac{11}{35} = \frac{431}{35} [/tex]

Step-by-step explanation:

[tex]15 \frac{3}{5} - 3 \frac{2}{7} \\ (15 - 3) + ( \frac{3}{5} - \frac{2}{7} ) \\ 12 + ( \frac{3}{5} - \frac{2}{7} ) \\ 12 + \frac{11}{35} [/tex]

Answer:

Area of geometric figures mentioned calculated.

Step-by-step explanation:

Square Perimeter = 4 x sides of square = 20. So, each equal side of square = 20 / 4 = 5

Area of square = ( Side )^2 = ( 5 )^2 = 25

Area of triangle = 1/2 (Base) (Height) = 1/2 x 3 x 3.5 = 5.25
