Answer:
atleast 52
Step-by-step explanation:
Given that an employment agency requires applicants average at least 70% on a battery of four job skills tests.
An applicant scored 70%, 77%, and 81% on the first three exams,
Since weightages are not given we can assume all exams have equal weights
Let x be the score on the 4th test
Then total of all 4 exams = ![70+77+81+x\\= 228+x](https://tex.z-dn.net/?f=70%2B77%2B81%2Bx%5C%5C%3D%20228%2Bx)
Average should exceed 70%
i.e.![\bar X \geq 70\\Total\geq 70(4) =280](https://tex.z-dn.net/?f=%5Cbar%20X%20%5Cgeq%2070%5C%5CTotal%5Cgeq%2070%284%29%20%3D280)
Comparing the two totals we have
![228+x\geq 280\\x\geq 280-228 = 52](https://tex.z-dn.net/?f=228%2Bx%5Cgeq%20280%5C%5Cx%5Cgeq%20280-228%20%3D%2052)
Hemust score on the fourth test a score atleast 52 to maintain a 70% or better average.
Area is length times width so
A = 4.5*3.4 which is 15.3.
The area of the rectangle is 15.3 cm
Answer: y - 6x +46
Step-by-step explanation:

y + <u>4</u> - 6x +<u>42</u>
y - 6x +46
Answer:
1)An angle bisector is basically the division of an angle into two equal parts, so you should just draw a line in the middle after you found the angles using the compass
2) parallel lines is a pair of lines that never intersect, and are always the same distance apart. you should use the compass to draw a 90-degree angle at the end of the line XY, and use the straightedge to draw a line that is parallel to the line XY.
Answer:
v = 1/3
Step-by-step explanation:
Given that:
-1 = 1/ 3v
Multiplying both sides by "v", we get:
-1 * v = (1/3v) *v
-v = 1/3 (As v in numerator will cancel v in denominator )
Now multiplying both sides by -1 to get positive v:
-1 * -v = -1 * 1/3
("-" sign into "-" gives "+") So,
v = 1/3
