Which linear function has the greatest y-intercept? y = 6 x + 1 On a coordinate plane, a line goes through points (0, 2) and (5, 0). On a coordinate plane, a line goes through points (1, 2) and (0, negative 3). y = 3 x + 4.

Answers

Answer:

y = 6x + 1 (0,2) (5,0)

Step-by-step explanation:

Really just need to pay attention where the x coordinate is at. If at 0, and the y coordinate is elsewhere, you will be able to tell where the y intercept is. Usually, you quickly draw a graph if the numbers are more complex.

Adding up the lengths of the exposed sides of the square would give you 40. You do not count the sides of the square in the middle because it's being covered by the 2 half circles.

We can use the 2 squares to measure the half circles. Since the circles cover 2 sides of the square, the circle is 20 units long on the flat side. To find the perimeter of the curves, you would at Pi into the equation.

Determine the lateral and total surface area of the pyramid.

Answers

Answer:                      

Lateral surface area = 45.5

Total surface area = 60.2

Step-by-step explanation: To find the lateral surface area, we first need to find the surface area of one triangle. For the triangle on the right/left, you multiply 3.5*5.8, which equals 20.3. Since this is a triangle, we multiply the product (20.3) by 1/2. The answer is 10.15. Since there are two triangles with the same dimensions as this, we multiply 10.15 by 2, which equals 20.3. For the triangle on the top/bottom, we multiply 4.2*6, which equals 25.2. Since this is a triangle again, we multiply 25.2 by 1/2. The answer is 12.6. Since there are two triangles with the same dimensions as this, we multiply 12.6 by 2, which equals 25.2. Now we add 20.3 + 25.2, which equals 45.5. This is the lateral surface area.

To find the total surface area, we now need to find the area of the base as well. To do so, we multiply 4.2 by 3.5, which equals 14.7. Now we add 45.5, the area of all the triangles, with 14.7, the area of the base. The answer is 60.2.

I hope this helps!

The ratio of almond pieces to
cranberry pieces in a salad is 3 to 4.
If there is a total of 28 pieces in
salad, how many are almond pieces
and how many are cranberry
pieces?

Answers

Answer: There are 12 almonds and 16 cranberries.

Step-by-step explanation:  This is a proportions problem.

If the ratio of almonds to cranberry is 3 to 4, that means for every 7 pieces, there are 3 almonds and 4 cranberries.If there are a total of 28 pieces, you need to multiply each piece of the original proportion by 4 (28/7 = 4).3 * 4 = 12 almonds4 * 4 = 16 cranberriesCheck: 12 + 16 = 28

Answer:

There are 12 almond and 16 cranberry

Step-by-step explanation:

almond : cranberry : total

3           :   4             : 3+4 = 7

We know there are 28 pieces

28/7 = 4

Multiply each piece by 4

almond : cranberry : total

3*4         :   4*4             :  7*4

12                  16                   28

There are 12 almond and 16 cranberry

Monica deposits ​$200 into a savings account that pays a simple interest rate of 3.3​%. Paul deposits ​$300 into a savings account that pays a simple interest rate of ​2.4%. Monica says that she will earn more interest in 1 year because her interest rate is higher. Is she​ correct? Justify your response.

Answers

Answer:

She is not because Paul deposited more money than her, which was enough so that he would earn more interest.

Step-by-step explanation:

Monica

i = prt

i = 200 * 0.033 * 12

(12 is represented as months)

Multiply.

i = 79.2

Paul

i = prt

i = 300 *  0.024 * 12

(you can choose months or years, but they have to be the same)

Multiply.

i = 86.4

Answer

Monica is wrong because Paul deposited more money than her, which was enough so that he would earn more interest.

Step-by-step explanation:

Answer:

-3.8x + 7 and c = -75/14 and/or c = -5.35714

Step-by-step explanation:

First equation:

1.2x + 7 - 5x =

Step 1 - Group like terms:

1.2 - 5x + 7

Step 2 - Add simliar elements:

1.2 x - 5x = -3.8x =

3.8x + 7

Answer: -3.8x + 7

Second equation:

2.2c - 3 = 2(6 - c) + 7c =

Step 1 - Multiply both sides by 10:

2.2c ⋅ 10-3 ⋅ 10 = 2(6 - c) ⋅ 10 + 7c ⋅ 10

Step 2 - Refine:

22c - 30 = 20(6-c) + 70c =

- Expand 20(6-c): 120 - 20c

22c - 30 = 120 - 20c + 70c

Step 3 - Add similar elements:

-20c + 70c = 50c =

22c - 30 = 120 + 50c

Step 4 - Add 30 to both sides:

22c - 30 + 30 = 120 + 50c + 30

Step 5 - Simplify:

22c = 50c + 150

Step 6 - Subtract 50c from both sides:

22c - 50c = 50c + 150 - 50c

Step 7 - Simplify:

-28c = 150

Step 8 - Divide both sides by -28:

-28c/-28 = 150/-28

Step 9 - Simplify:

c = -75/14

Answer:

Fraction form: c = -75/14

Decimal form: c = -5.35714
