130% changed to a decimal is 1.3.
Multiply 1.3 by $20= $26.00
The number of beads that are gold is 35.
<h3>How many gold beads are there?</h3>
Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.
Number of gold beads = percentage of gold beads x total number of beads
70% x 50
0.7 x 50 = 35

Here you have two sets of parentheses. Order of operations rules (PEMDAS) require that you perform any operations that are presented within parentheses first. Mult and div come next, and then any addition and/or subtraction.
We must perform the addition 4+8 first; the correct outcome is 12. Then we have:
16 • [(12)÷4]
We must perform the operation inside brackets first:
16*[3] = 48 (answer)
Answer:
7√2
Step-by-step explanation:
Knowing that the angle is 45° (or π/4 radians) and the opposite leg has a length of 7, you can find the length of b with:
7 / b = sin(π / 4)
7 / (sin(π / 4)) = b
b = 7 / (1 / √2)
b =7√2
A simpler way to get the answer is to note that a right triangle with one 45° angle must be an isoceles right triangle, so both legs are the same length. Using the Pythagorean Theorem:
a² + 7² = b²
Since we know a = 7,
7² + 7² = b²
b = √(2 * 49)
b = 7√2
