The first one
Step-by-step explanation:
Answer:
∠ 4
Step-by-step explanation:
range is the values for y: y can be (including) -6 all the way up to (not including) 4
You have to find the ratio used to turn 24 into 18 inches then use that same ratio to turn 18 inches into the answer so it would be 4:3 ratio because 24:18 simplified is 4:3 if you do the same to the side that’s originally 18 you would devise it by 4 then multiply that number by 3 to get the length on the second triangle
Q1. The answer is <span>1 over 5 to the 3rd power.
</span>5 to the 5th is 5⁵
5 to the 8th is 5⁸
5 to the 5th over 5 to the 8th is
To simplify, we will use two rules:
Therefore:
is the same as 1 over 5 to the 3rd power.
Q2. The answer is <span>(53)−4.
The exponents are multiplied when are expressed in the form:
</span>
So,
Other choices are incorrect:
<span>one third to the 4th times one third to the 7th is </span>
3 to the 7th over 3 to the 15th is
<span>45 ⋅ 42 is </span>
- Charmi cut a ribbon into 19 pieces . 7 of them are 11 cm each and the rest are 8 cm each .
- What was the length of the ribbon at first ?
<h2>Explanation:</h2>
<h3>Given:</h3>
- Total pieces of ribbon is 19.
- Rest (12) pieces are of 8 cm.
<h3>To Find:</h3>
- What was original the length of ribbon ?
<h3>Solution:</h3>
Let original length of ribbon was x cm. Therefore,
➟ Length of ribbons of 11 cm = No. of pieces(11)
⟹ Total length = 7(11)
⟹ 77 cm....(1)
➼ Length of ribbons of 8 cm = No. of pieces(8)
⟹ Total length = 12(8)
⟹ 96 cm.....(2)
<em><u>According</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>question</u></em><em><u>, </u></em>
Original ribbon = Equation 1 + Equation 2
- ⟹ x = Sum of length of ribbons (11 cm and 8 cm)
- ⟹ x = 77 + 96
- ⟹ x = 173 cm
Hence, original length of ribbon at first was 173 cm. (Option a is correct)
