Answer: 13440 grams

Step-by-step explanation:

Since 1 kg is 1000 g, multiply 0.64 by 1000 to find how many grams are in a kilogram.

0.64x1000

=640 grams

She uses 640 grams each day.

How many grams does he use in 3 weeks?

1 week has 7 days

3 weeks has 21 days

3x7=21

640x21

13440 grams

Answer:

If a basketball player consistently shoots 80% from the free throw line and she takes 25 free throw shots throughout the course of a game, how many free throws can she be expected to make?

A basketball player makes 75% of the free throws that he attempts. What is the probability, approximated, that he succeeds in half of them in 40 trie

Answer:

The measure of the arc length is 62 degrees

Step-by-step explanation:

Here, we want to find the given arc measure

Mathematically, we are going to use the angle arc relationship

For the angle arc relationship, the measure of the central angle is simply the measure of the arc

In this case, the central angle is 62: this means that the given arc measure is 62 degrees too

the average amount of times students went out to eat

Answer:45

Step-by-step explanation: just add 1+1,2+2,3+3+3+3,+4,+5,+6+6+6

Answer:

$317

Step-by-step explanation:

Formula for compound interest is;

A = P(1 + (r/n))^(nt)

For melanie;

P = $3800

r = 2⅜% = 0.02375

n = 12/4 = 3

t = 16 years

Thus;

A = 3800(1 + (0.02375/3))^(3 × 16))

A ≈ $5548

For Sébastien;

P = $3800

r = 2¾% = 0.0275

n = 12

t = 16

Thus;

A = 3800(1 + (0.0275/12))^(12 × 16))

A ≈ 5865

Difference between Sébastien and Melanie's final amount = $5865 - $5548 = $317

Answer:

2/3

Step-by-step explanation:

3/4 x 8/9 = 24/36 or 2/3 simplified

Answer:

SAS

Step-by-step explanation:

Given: Two triangles ΔABD and ΔDCA,  

We have, AD=AD (normal)  

∠A=∠A (Given)  

BA=CD (Sides inverse to rise to points are consistently equivalent)  

With the SAS rule of congruency,  

ΔABD≅ΔDCA

Answer:

Step-by-step explanation:

Answer:

a = 30°

b = 11°

Step-by-step explanation:

JK = 360 - 110 - 130 - 54 = 66°

Inscribed angles = 1/2 their arc

∠K = 1/2(130 + 54) = 92°

∠J = 1/2(110 + 130) = 120°

∠M = 1/2(66 + 110) = 88°

8b = 88°

b = 11°

∠L = 1/2(54 + 66) = 60°

2a = 60°

a = 30°

Answer:

Red- 1/4 or 25% chance

Number less than six- 5/8 or 62.5% chance

Answer:

5 / 8 = 0.625 is best equivalent.

Answer:

2.57 and 11/3 and 3.14

Step-by-step explanation:

Answer:

$16

Step-by-step explanation:

Find the mean by adding all of the costs, and dividing it by 6, since there are 6 CDs

(12 + 13 + 20 + 20 + 12.5 + 18.5) / 6

96 / 6

= 16

So, the mean is $16

Answer:

yeah you just have to hope you got it correct until they tell you or give you brainliest

Answer:

Step-by-step explanation:

I think you mean 3(x+8)², not 3(x+8)2. If you cannot type ², use ^ to mark the exponent: 3(x+8)^2.

3(x+8)² + 8 = 83

3(x+8)² = 75

(x+8)² = 25

x+8 = ±√25

x+8 = ±5

x = -8 ± 5 = -3, -13

Step 2

Step-by-step explanation:

Answer:

2/19

Step-by-step explanation:

Answer:

s = 47

Step-by-step explanation:

The measure of the exterior angle of a triangle is equal to the sum of the opposite interior angles

s+45 = s+6  + s-8

Combine like terms

s+45 = 2s-2

Subtract s from each side

s+45-s =2s-2-s

45 =s-2

Add 2 to each side

45+2 = s-2+2

47 =s

Answer:

Lilly, since the angles are the same we can set the equal to each other, that's the "trick" of this problem

Step-by-step explanation:

3x + 50 = 6x - 10

3x + 60 = 6x

60 = 3x

20 = x

see how I got that?

Answer:

The slope is y=0.59x so 0.59

The y intercept is 0

Answer: 110ft2

Step-by-step explanation:

Answer:

419 or 419.37

Step-by-step explanation:

55 x 6.625 = 364.375

364.375 = 364.37 (Rounded to the Nearest 10)

55 + 364.37 = 419.37

--------------------------⭐OR⭐------------------------------

55 x 6.625 = 364.375

364.375 = 364 (Rounded)

55 + 364 = 419

heyhey! your in luck, Im here again <3

Step-by-step explanation:

The coordinates are ( 1,2 ) . In answer, its B. Why? Well the distance in between was 5, and the middle landed right after the line, which landed of the coordinates ( 1,2 ) . Your welcomee!

Answer:

Step-by-step explanation:

a) y=[tex]x^{2} -4x[/tex]

x=-1 ⇒ y=[tex](-1)^{2} +4=1+4=5[/tex]

x=1    ⇒  y=[tex]1^{2} -4=1-4=-3[/tex]

x=2 ⇒   y=[tex]2^{2} +8=4-8=-4[/tex]

x=4   ⇒  y=[tex]4^{2} -16=16-16=0[/tex]

b) [tex]x^{2} -4x[/tex]=[tex]x^{2} -4x+4-4=(x-2)^{2}-4[/tex]

so the blue one

The necklaces will be sold for $8.75.

All you have to do is devide 201.25 by 23 and you will get your answer.
