Answer:
The area of trapezium is (x+11) cm².
Step-by-step explanation:
Given that the formula of area of trapezium is :
In the formula, a and b represents the length of trapezium and h is the height. So you have to substitute the following expressions into the formula :
Answer:
x = 348
Step-by-step explanation:
From the given we can tell it a supplementary angle.
<u>Don't know what supplementary angle is?</u>
<em>Supplementary angle are angles that :</em>
<em>Equal 180 °</em>
<em />
<u><em>Solve: </em></u>
<em>Since,</em>
<em>∠ABD is (0.18x+54)° </em>
<em>∠CBD is (0.07x+39)°</em>
<em />
<em>Thus,</em>
<em>(0.18x+54) + 0.07x + 39 = 180</em>
<em>Group likes terms:</em>
<em>0.25x + 54 + 39 = 180</em>
<em>0.25 + 93 = 180</em>
<em>Subtract 93 from both sides</em>
<em>0.25x = 87</em>
<em>x = 348</em>
<em />
<em>Check Answer:</em>
<em>0.18(348) + 54 + 0.07(348) + 39 </em>
<em>= 180</em>

Answer:
i jus passed hella gas ngl
Step-by-step explanation:
<span>In an arithmetic sequence, if a4 = 18 and a10 = 30, determine a1, d, and an.
Then write the first four terms of the sequence.
Use the formula L = A + (N-1)D, where L represents the nth term.
Then, based upon the given info,
18 = A + (4-1)D and 30 = A + (10-1)D.
The first equation boils down to 18 = A + 3D, so that A = 18 - 3D. Subst. 18-3D for A in the second equation: 30 = 18-3D + 9D. Then 12=6D and D = 2.
</span><span>
Use </span>A = 18 - 3D to determine the value of A. Recall that D=2.
Then A = 18 - 3(2), or A = 18-6, or A = 12.
Then L = A + (N-1)D becomes L = 12 + (N-1)(2).
First term is 12. Next is 14; next is 16; last is 18.
Answers:
<u>5) A.) 26</u> and <u>6) D.) 30</u>
Step-by-step explanations:
<em>Question 5)</em>
For this question, we need to analyze the graph given and look at how many people scored 601 or above on the math portion. So, looking at the answers given we aren't going to have a smaller number of only 16 or 10, since they are both equal to or higher than 601. So, we need to add the amount of students that scored the 601 or higher amount.
16 + 10 = 26.
This answer matches up with the answer given of A).
<em>Question 6)</em>
For this question, it is similar except you don't add the numbers given. Instead, the question is asking for a specific amount given. So, looking at the answers given, yes 18 and 6 did score below 500, but the question asked "...scored <u>500 or below</u>?" This is a specific question telling us about the 500 or below, which is in one column. As shown in the graph, 30 students scored this specific amount, which gives us our answer of D).
I hope that this helps.
