Heather made 4 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 4 necklaces was $23.60. If the beads
cost a total of $12.40, how much did each pendant cost?

Answer:

$2.80

Step-by-step explanation:

23.60 - 12.40 = 11.2

11.2 ÷ 4 = 2.80

1. What is the range of frequencies a human ear can hear?

Answers

Answer:

Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz.

(Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)

Geometry problem above^^^ In the figure at the right FGH ~ KLJ....

Answers

Answer:

x = 12

y = 4.5

Step-by-step explanation:

Since ∆FGH ~ ∆KLJ, therefore, we would have the following proportion:

[tex] \frac{FG}{KL} = \frac{GH}{LJ} = \frac{FH}{KJ} [/tex]

[tex] \frac{9}{y} = \frac{x}{6} = \frac{6}{3} [/tex]

✔️Let's solve for x using:

[tex] \frac{x}{6} = \frac{6}{3} [/tex]

Multiply both sides by 6

[tex] \frac{x}{6}*6 = \frac{6}{3}*6 [/tex]

[tex] x = \frac{6*6}{3} [/tex]

[tex] x = 12 [/tex]

✔️Solve for y using:

[tex] \frac{9}{y} = \frac{6}{3} [/tex]

Cross multiply

[tex] y*6 = 3*9 [/tex]

6y = 27

y = 27/6

y = 4.5

In the figure, O is the centre of a circle passing through points
A, B, C and D and ADC = 120
Find the value of x.

Answers

Answer:

30 degrees

Step-by-step explanation:

The computation of the value of x is given below:

Given that

ADC = 120 degrees

So ABC = 60 degrees

As the sum of the opposite angles are 180 degrees

And ACB = 90 degrees

Now in Triangle ADC

Angle ACB + Angle ABC + x = 180 degrees

90 + 60 + x = 180

x = 30 degrees

Answers

Answer:

If you really meant that the number of dogs is 12 greater than 3 times the number of cats then:

3 cats

Step-by-step explanation:

21= number of dogs

c = number of cats

21 = 12 + (3c)

3c = 9

A 34 foot tall poll is supported by 2 wires that are anchored 8 feet from the base of the pole how many feet or wire is needed for the support wires

Answers

Using the Pythagorean theorem:

Length of wire = sqrt(34^2 + 8^2)

Length of wire = sqrt(1156 +64)

Length of wire = sqrt(1220)

Length of wire = 34.9285 feet

There are 2 wires:

34.9285 x 2 = 69.857 feet

Round off as needed.

Answer:

34.93 feet

Step-by-step explanation:

Using a^2+b^2=c^2

we can substitute a and b in which is

34^2+8^2=c^2

1156+64=c^2

1220 = c^2

Now we need to square both sides

√1220 = √c^2

34.9284983931 ----> 34.93

34.93 = c

c = 34.93

Ani spent a total of $7.53 at a store. She bought some cereal for $3.67. She also bought 6 peaches.
If each peach cost the same amount, which equation can be used to find the cost of each peach, P?
A. P = $7.53-6
B. P = $3.67 6
C. P= $7.53 - ($3.67=0
D. P= ($7.53 - $3.67) = 6
E. P= ($7.53 + $3.67) = 6

Answers

Answer:

Step-by-step explanation:

It says she spent $7.53 at the store and she bought (SOME) cereal for $3.67

so we have to find how much the 6 peaches cost. To find it out we are going to have to subtract the cereal she bought from $3.67 and the money she wasted total so its going to be D.

a book which cost 300 naira was sold for 240naira.what was the loss percentage?

Answers

Answer:

20%

Step-by-step explanation:

Since the original price of the book is 300 naira...

100% = 300 naira

1% = 300 ÷ 100 = 3 naira

240 ÷ 3 = 80

Since 80% is the percentage of the price after the loss..

100 - 80 = 20%
