(a) The perimeter of a rectangular field is 372 m.
If the width of the field is 87 m, what is its length?
Answers
Answer:
98 m
Step-by-step explanation:
Answer:
The length of the field is 99 m.
Step-by-step explanation:
First, multiply 87 by 2 to get 174. Then, subtract 174 (total of the two width sides) from 372 (total perimiter) to get 198. Lastly, divide 198 by 2, because 198 is the total of the 2 length sides, and you will get 99 m per length side.

Answers
Answer: 72.3
Step-by-step explanation: least to greatest would be 68.92, 69.15, 72.3, 73.2

The product of two consecutive positive integers is 1,332. Explain how you can write and solve a quadratic equation to find the value of the larger integer.
Answers
x - the larger integer (x>0)
x-1 - the smaller integer (the difference between two consecutive integers is always 1)
The product of two consecutive positive integers is 1,332
so:
x•(x -1 ) = 1332
x² - x = 1332
x² - x - 1332 = 0 ⇒ a = 1, b = -1, c = -1332
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-1)\pm\sqrt{1^2-4\cdot1\cdot(-1332)}}{2\cdot1}=\dfrac{1\pm\sqrt{1+5328}}{2}\\\\\\x_1=\dfrac{1+\sqrt{5329}}{2}=\dfrac{1+73}{2}=37\\\\x_2=\dfrac{1-\sqrt{5329}}{2}\ \not>\ 0[/tex]
x = 37
Answer:
The numbers can be written as x and x + 1. Set the product of the numbers equal to 1,332 to get x(x + 1) = 1,332. You can solve the quadratic equation by using the quadratic formula, completing the square, or factoring. When you solve the quadratic equation, you find that x = –37 and 36. Since the question asked for positive integers, the only viable solution is x = 36. To solve for the larger integer, you add 1 to 36 to get an answer of 37.

Answers
Answer:
they all equal 105°
Step-by-step explanation:
Answer:
∠ 2 = ∠ 5 = ∠ 7 = 105°
Step-by-step explanation:
∠ 2 and ∠ 3 are same- side interior angles and are supplementary, thus
∠ 2 = 180° - ∠ 3 = 180° - 75° = 105°
∠ 5 and ∠ 2 are vertical angles and congruent, thus
∠ 5 = 105°
∠ 2 and ∠ 7 are alternate angles and congruent, thus
∠ 7 = 105°

joe measured a brick using a ruler with centimeters and got 9 cm. he then measured the same brick using a ruler with millimeters and got 90 mm. are these measurements equivalent?
Answers
Answer:
yes
Step-by-step explanation:
1 cm=10mm. if 1cm=10mm what about 9cm
Yes, they are equivalent when he got 9 cm and we got 90 mm while measuring it.
Calculation of the measurement:Since he used the ruler with centimeters and got 9 cm
And, if he used a ruler with millimeters and got 90 mm
So the measurement should be equal
As we know that 1 cm=10mm
So based on this, they are equivalent
