7th grade math help me pleaseeee

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:

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:

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:

5 / 8 = 0.625 is best equivalent.

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

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

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]

Answer: 110ft2

Step-by-step explanation:

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

Answer:

Red- 1/4 or 25% chance

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

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:

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

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:

Its a trick question

Step-by-step explanation:

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: 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
