HELP ASAP how do you find the missing angle measurement In s set complementary angles
Answer:
x + y =90
Step-by-step explanation:
So to find any angle in a complementary set you would subtract the angle given by 90.
Easy way to remember what complementary means is the C is like the curve of 9 in 90 and in supplementary the S is like half a 8 in 180.
the sum of five consecutive numbers is 700, what is the first number?
Answer:
The first number is 138.
Step-by-step explanation:
Let the first number be x.
Then since they are consecutive numbers, the second number will be (x + 1), the third (x + 2), the fourth (x + 3) and the fifth being (x + 4).
We are given that their sum is 700. Therefore:
[tex]x+(x+1)+(x+2)+(x+3)+(x+4)=700[/tex]
Solve for x. Combine like terms:
[tex]5x+10=700[/tex]
Subtract 10 from both sides:
[tex]5x=690[/tex]
Divide both sides by five. Therefore:
[tex]x=138[/tex]
The first number is 138.
Answer:
138
Step-by-step explanation:
(n) + (n+1) + (n+2) + (n+3) + (n+4) = 700
5n + 10 = 700
5n = 690
n = 138

Answer:
∠ 1 = 94°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
130° is an exterior angle of the triangle, then
∠ 1 + 36° = 130° ( subtract 36° from both sides )
∠ 1 = 94°
Which Relationships have the same constant of proportionality between Y and X the following table?
Answer: do you have a picture
Step-by-step explanation:
Carl can paint a room 3 hours faster than Jennifer can. If they work together, they can complete the job in 2 hours. Using complete sentences, explain each step in figuring out how to determine the time it would take Jennifer to complete this job on her ow
Answer:
If they would both work at the same speed they would each take 4 hours to complete the room. So in total they would work 8 hours. But because Carl can finish three hours before Jennifer 3 hours of the eight already got to Jennifer. Then we divide the resting 5 hours by the two and then we have:
Jennifer:
3+2,5=5,5
Carl:
2,5

Write the given equation in exponential form.
Log8 1/512 = 3
Need helpppp assignments due tomorrow :(
Answer:
8^(-3) = 0.00195 or 1/512
Step-by-step explanation:
Given: "the log to the base 8 of 1/512" is 3 is actually false. The correct version is "the log to the base 8 of 1/512" is -3 (negative 3). (Log form.)
Please note: 8^(-3) = 0.00195 or 1/512 (This is in exponential form.)

[tex] \frac{x + 2}{3x - 1} [/tex]
Step-by-step explanation:
Things you should before solving this question :-
a²- b² = (a + b)(a - b)where a and b are any two variables.
SIMPLIFYING THE EXPRESSION
[tex] \frac{ {x}^{2} - 9 }{3 {x}^{2} + 8x - 3} \div \frac{x - 3}{x + 2} \\ [/tex]
using the identity discussed above
[tex] \frac{ (x + 3)(x - 3) }{3 {x}^{2} + 8x - 3} \div \frac{x - 3}{x + 2} [/tex]
simplifying 3x² + 8x - 3
[tex] \frac{ {x}^{2} - 9 }{3 {x}^{2} + 9x -x - 3} \div \frac{x - 3}{x + 2} [/tex]
as 8x can be written as 9x - x
[tex] \frac{ (x - 3)(x + 3) }{3 {x}(x + 3) - 1(x + 3)} \div \frac{x - 3}{x + 2} \\ \frac{ (x - 3)(x + 3) }{(3 {x} - 1)(x + 3) } \div \frac{x - 3}{x + 2} [/tex]
flipping the fraction that follows division sign and inserting multiply in place of divide
[tex] \frac{ (x - 3)(x + 3) }{(3 {x} - 1)(x + 3) } \times \frac{x + 2}{x - 3} [/tex]
canceling (x - 3) and (x + 3) as they're common in both denominator and numerator
[tex] \frac{x + 2}{3x - 1} [/tex]

Question 4 options:
A figure with an area of 84 square cm is dilated by a factor is 2. The area of the dilated figure is ___ square cm.
Answer:
what ever sides are multiply the points by 2 each (x time 2, y times 2) Best I got. Hope this helps some
Step-by-step explanation:
figure out the sides then:
Ex. Perform a Dilation of 4 on point A (2, 3) which you can see in the picture below. Multiply the coordinates of the original point (2, 3), called the image, by 4. Image's coordinates = (2 * 4, 3 * 4) to get the coordinates of the image (8, 12).
Since this is the area x 2, multiply 84x2

Out of 200 students in a school, 30 have brown sandals. What is the probability that a student chosen at random would have brown sandals?
Answer:
There is a 15% chance a student chosen at random would have brown sandals.
Step-by-step explanation:
The required probability will be 0.15 that a student chosen at random would have brown sandals.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
the probability = number of favorable outcomes / total number of outcomes.
We have been given that out of 200 students in a school, 30 have brown sandals.
To determine the probability that a student chosen at random would have brown sandals.
The probability = number of favorable outcomes / total number of outcomes.
The probability = 30 / 200
The probability = 0.15
Thus, the required probability will be 0.15 that a student chosen at random would have brown sandals.

Answer:
Step-by-step explanation:
If the coordinates are (0, a) and (b, 0), we just use the distance formula to find the distance in terms of a and b:
[tex]d=\sqrt{(0-a)^2+(b-0)^2}[/tex] and
[tex]d=\sqrt{(-a)^2+b^2}[/tex] which simplifies to
[tex]d=\sqrt{a^2+b^2}[/tex]
and that's it!
