Answer:
x is 55 and the perimeter is 120
Step-by-step explanation:
55+55 is 110 and 5+5 is 10 so that all adds up to 120
Answer:
-3
Step-by-step explanation:
We know that both the larger triangle is dialated by some factor.
To start divide the two given sides:
36/24=1.5
This means that the larger triangle is dialated by a factor of 1.5, meaning that all sides of the smaller triangle must be multipled by 1.5 to get the larger triangle.
By knowing that we can multiply 3x-7 by 1.5 and set it equal to 6x-6.
1.5(3x-7)=6x-6
4.5x-10.5=6x-6
-6x+4.5x=10.5-6
-1.5x=4.5
x=(4.5)/(-1.5)
x= -3
Answer:
<h3>5 hours</h3>
Step-by-step explanation:
12 songs are played in= 1 hour
Thus, 60 songs are played in = 60 ÷ 12 = 5
<em>Thus, 60 songs are played in 5 hours.</em>
Properties of polygons.
Step-by-step explanation:
(1) Both pair of opposite sides are congruent. <u>Distance Formula</u>
(2) Both pairs of opposite sides are parallel. <u>Slope Formula</u>
(3) Diagonals are congruent . <u>Distance Formula</u>
(4) Diagonals bisect to each other. <u>Midpoint Formula</u>
(5) Diagonals are perpendicular. <u>Slope Formula</u>
(6<u>)</u> Sides of polygon create a right angle. <u>Slope Formula</u>
(7) A triangle is isosceles /equilateral. <u>Distance Formula</u>
To solve this we use the z statistic. The formula for z
score is:
z = (x – u) / s
where x is the sample value = less than 16, u is the
sample mean = 16.1, s is standard dev = 0.1
z = (16 – 16.1) / 0.1
z = - 1
From the standard distribution tables at z = - 1,
P (z = -1) = 0.1587
