Answer:
3t
Step-by-step explanation:
7t-3t+4t-5t
Combine like terms
7t -3t = 4t and substitute back into the expression
4t +4t -5t
4t+4t = 8t and substitute back into the expression
8t - 5t
3t
5/8 * 125/125 = 625/1,000 = 0.625
62.5 percent
Solution: 62.5%
Answer:
€99
Step-by-step explanation:
The computation of the original price (before the rebate) of this pair of shoes is shown below:
Given that
The cost of pair of shoes is € 69.30 i.e. after 30% discount
So, the original price would be
= € 69.30 × 100 ÷ 0.70
= €99
The € 69.30 shows the 70% value according to this we determine 100% value
Option C:
The measure of arc CD is 40°.
Solution:
Given data:
m∠X = 11° and m(arc AB) = 18°
To find the measure of arc CD:
We know that,
<em>Angle formed by two intersecting secants outside the circle is equal to half of the difference between the intercepted arcs.</em>
![$m \angle X =\frac{1}{2}({arc \ CD}-{arc} \ AB)](https://tex.z-dn.net/?f=%24m%20%5Cangle%20X%20%3D%5Cfrac%7B1%7D%7B2%7D%28%7Barc%20%20%5C%20CD%7D-%7Barc%7D%20%20%5C%20AB%29)
![$ 11^\circ =\frac{1}{2}({arc} \ CD-{18^\circ})](https://tex.z-dn.net/?f=%24%2011%5E%5Ccirc%20%3D%5Cfrac%7B1%7D%7B2%7D%28%7Barc%7D%20%20%5C%20CD-%7B18%5E%5Ccirc%7D%29)
Multiply by 2 on both sides.
22° = arc CD - 18°
Add 18° from both sides.
40° = arc CD
Switch the sides.
arc CD = 40°
Hence the measure of arc CD is 40°.
Option B is the correct answer.
