Answer:

$3.90

Step-by-step explanation:

The total cost was $24.40.

We know the cost for beads for each necklace is also $2.20, multiply this by four to find the cost of the beads for all the necklaces.

$2.20 × 4 = $8.80

Now we will subtract this from the total price.

$24.40 - $8.80 = $15.60

$15.60 Is the remaining cost for the pendants of all four necklaces. We will now divide this by four to find the price of a single pendant.

$15.60 ÷ 4 = $3.90

<u>This means the cost of each pendant is $3.90</u>

2.20•4=8.80 so if you subtract that by 24.40 you get 15.60 and if you divide that by 4 you get 3.90 for each pendant. If you wanna check it you can add 3.90 and 2.20 together and multiply it by 4 and you get 24.40

What are the vertex and x-intercepts of the graph of the function below?
geniusboy [140]

y= x^2 - 6x-7

Vertex = -b /2a

b= -6

a= 1

-(-6)/2(1)= 3

x= 3

Use the substitution method to find y

y= (3)^2-6(3)-7

(3)(3)-18-7

9-25

y= -16

Vertex is (3, 16)

Find x- intercept (y= 0)

y= x^2 - 6x-7

(x-7)(x+1)

x-7= 0

Move -7 to the other side. Sign changes from -7 to 7

x-7+7= 0+7

x= 7

x+1= 0

Move +1 to the other side. Sign changes from +1 to -1

x+1-1= 0-1

x= -1

Answer :B. Vertex: (3, -16); Intercepts: x=-1,7

If ED is tangent to circle H, find the value of x
AnnyKZ [126]

Answer:

x = 8

Step-by-step explanation:

Here, we want to find the value of x

According to the theorem;

45 = 1/2(147 - (7x-5))

90 = 147 -7x + 5

90 = -7x + 147

7x = 147-90

7x = 57

x = 57/7

x = 8.142 which is approximately 8

Find the missing side or angle. Round to the nearest tenth. C=53° B= 80° a=2 b=[ ? ]​
Degger [83]

9514 1404 393

Answer:

  b ≈ 2.7

Step-by-step explanation:

The missing angle A is ...

  A = 180° -53° -80° = 47°

The law of sines tells you ...

  b/sin(B) = a/sin(A)

  b = sin(80°)×2/sin(47°) ≈ 2.6931

Side b is about 2.7 units.
