Answer:

8.49 units

Step-by-step explanation:

CD is the length opposite angel E

Use cosine law

CD² = 10² + 5² - 2(10)(5)cos(58)

CD² = 72.00807358

CD = 8.485757101

CD = 8.49 units

A baker uses 30 grams of sea salt for each batch of bread. Sea salt comes in an 18-kilogram package or an 800-gram package. Whic

inessss [21]

Baker should use 18-kilogram pack so that no salt is left in the end.

Step-by-step explanation:

In order to find which bag should he buy, we have to check for which bag the 30 grams salt can be taken out completely i.e. which quantity is divided by 30 grams completely.

If a quantity is not divided by 30 completely that means that there will be salt left.

so,

For 800-grams pack:

Salt for one batch of bread = 30-grams

Batches from 800-grams of salt:

$= \frac{800}{30}\\=26.66\ \$

First of all we have to convert the kilograms into grams

As there are 1000 grams in one kilogram,

18 kg = 18*1000 grams = 180000 grams

Batches of bread from 18 kg salt:

$=\frac{18000}{30}\\=600\ batches$

As the 18-kilograms is completely divided by 30, so after 600 batches no salt will be left but in 800 gram pack after 26 batches salt will be left.

So,

Baker should use 18-kilogram pack so that no salt is left in the end.

I need help!!!! I don’t understand this!

Nana76 [90]

To find the angles in these problems you have to do one of two things.

1) If we are looking for an interior angle with the exterior angle given, we can find the interior angle by subtracting the exterior angle from 180.

EX: Exterior angle K is 140. Therefore the interior angle is 40 (180 - 140 = 40).

2) If order to find an interior angle when you have other interior angles, add up the other interior angles and subtract them from 180.

EX) Interior angle A is 32 because the other angles are 120 and 28. (180 - 120 - 28 = 32)

ALSO, remember that the square is equal to 90 degrees. I've included an answer list for you below.

A = 32

B = 152

C = 65

D = 25

E = 37

F = 83

G = 97

H = 97

I = 83

J = 57

K = 40

L = 120

M = 60

N = 90

O = 79

P = 12
