x(x + 2) = xx + x · 2

Simplify:

x² + 2x

x(2x - 5)

Carl is having a party. He has bought 24 brownies and is making 6 more batches of brownies. The inequality below can be used to determine how many brownies, b, must be in each batch so that all 138 guests get at least 1 brownie. Determine which of the given values, if any, make the inequality true: b=10, b=15, b=20 *

Answers

Answer:

b = 20

Step-by-step explanation:

The computation is shown below

Given that

24+ 6b > 138

where

b = 10

b = 15

b = 20

So if we take b = 10

= 24 + 6(10)

= 24 + 60

= 84

B = 15

= 24 + 6(15)

= 24 + 90

= 114

B = 20

= 24 + 6 (20)

= 24 + 120

= 144

So if we take b = 20 the inequality would be true

Sara was making a cookies and she needs ½ cup of Chocolate chips and 2/3 cup of sugar. She accidently put in 1 cup of sugar. How many cups chocolate chips does she need now?

Answers

Answer:

3/4 cups of Chocolate chips is needed

Step-by-step explanation:

Sara was making a cookies and she needs ½ cup of Chocolate chips and 2/3 cup of sugar. She accidently put in 1 cup of sugar. How many cups chocolate chips does she need now?

From the above question:

2/3 cup of sugar = ½ cup of Chocolate chips

1 cup of sugar = x

Cross Multiply

2/3 cup of sugar × x = ½ cup of Chocolate chips × 1 cup of sugar

x = ½ cup of Chocolate chips × 1 cup of sugar/ 2/3 cup of sugar

x = 1/2 ÷ 2/3

x = 1/2 × 3/2

x = 3/4 cups of Chocolate chips

Therefore, for 1 cup of sugar , 3/4 cups of Chocolate chips is needed

What is perimeter?

In geometry, the perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape. It is measured in linear units of measurement like centimeters, meters, inches, or feet.

Given,

Straight length of the track = 1000 meters on each side

total straight length = 2 × 1000 = 2000 meters

Curves are semicircles on each side having diameter of 74 meters

which makes a complete circle

Perimeter of circle = π × diameter

                               = π × 74 = 232.477856 meters

Total distance in meters = 2000 + 232.477856

                                        = 2232.477856

Hence, 2232.48 meters is the total distance around the entire track.

All dreaded it all sought to avert it. While the inaugural address was being delivered from this place, devoted altogether to saving the Union without war, insurgent agents were in the city seeking to destroy it without war seeking to dissolve the Union, and divide effects, by negotiation. Both parties deprecated war; but one of them would make war rather than let the nation survive; and the other would accept war rather than let it perish. And the war came.One eighth of the whole population were colored slaves, not distributed generally over the Union, but localized in the Southern part of it. These slaves constituted a peculiar and powerful interest. All knew that this interest was, somehow, the cause of the war. To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union, even by war; while the government claimed no right to do more than to restrict the territorial enlargement of it. Neither party expected for the war, the magnitude, or the duration, which it has already attained. Neither anticipated that the cause of the conflict might cease with, or even before, the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible, and pray to the same God; and each invokes His aid against the other. It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces; but let us judge not that we be not judged.
