Answer:
6.93
Step-by-step explanation:
use a²+b²=c² to find that missing length.
8²=4²+b²
64=16+b²
48=b²
take the square root of 48 and you get 6.93.

Is AABC-ADEF? If so, identify the similarity postulate or theorem that applies 30- A
Answers
Answer:
C. Similar - AA
Step-by-step explanation:
From the diagram given, we know that all 3 angles of ∆ABC are congruent to all corresponding 3 angles of ∆DEF.
If we know just two of the angles of the two triangles given are equal to each other, it is enough information for us to prove that they are similar to each other based on the AA Similarity theorem.
The corresponding three angels of both triangles are equal, therefore, based on AA, they are similar to each other.
A ball is thrown in the air from the top of a building. Its height, in meters above ground, as a function of time, in seconds,
is given by h(t) = -4.9t? + 16 + 13. How long does it take to reach maximum height? (Round your answer to three
decimal places.)

Answers
Answer:
It takes 1.633 seconds for the ball to reach maximum height.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, f(x_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]f(x_{v})[/tex]
In this question:
We have that the height is given by:
[tex]h(t) = -4.9t^2 + 16t + 13[/tex]
So [tex]a = -4.9, b = 16, c = 13[/tex].
The maximum height happens at the instant of time:
[tex]t_v = -\frac{b}{2a} = -\frac{16}{2(-4.9)} = \frac{16}{9.8} = 1.633[/tex]
It takes 1.633 seconds for the ball to reach maximum height.

Martha will build a pool in her backyard. She wants the pool to have a rectangular shape
and to be five meters long and three meters wide. What would the area in Martha's backyard that will be lost due to the construction of the pool? There are 3.28084 feet in
one meter.
A 15 square feet
B 80.729 square feet
C 161.459 square feet
D 322.918 square feet
Answers
9514 1404 393
Answer:
C. 161.459 square feet
Step-by-step explanation:
In feet, the dimensions of the pool are ...
(5 m)(3.28084 ft/m) = 16.4042 ft
(3 m)(3.28084 ft/m) = 9.84252 ft
Then the area of the pool is ...
(16.4042 ft)(9.84252 ft) = 161.458666584 square feet
about 161.459 square feet
_____
Additional comment
If you consider that a square meter is slightly less than 11 square feet, the pool area can be estimated to be (5 m)(3 m)(11 ft²/m²) = 165 ft². This is close enough to point you to the correct answer choice.

Question 8 (1 point) Mrs. Hernandez is making a circular skirt for her daughter's Valentine banquet. She will glue a piece of sequin trim at the edge of the skirt. If the diameter of the circular skirt is 36 inches, what will be the closest measurement needed for the sequin trim in inches? 113 inches 57 Inches 1017 inches 72 inches
Answers
Answer: 113 inches
Step-by-step explanation:
To solve the question, we have to find the perimeter of a circle since the skirt is circular. This will be:
Perimeter = 2πr
where
π = 3.142
r = diameter/2 = 36/2 = 18
The closest measurement needed for the sequin trim will then be:
= 2πr
= 2 × 3.142 × 18
= 113.112
= 113 inches
20 books are divided parcels, each parcel contains one fifth of the total. If a librarian wants to buy 16 books how many fifths should he take?
Answers
Answer: x=4
Step-by-step explanation:
1/5 of the total= 1 parcel= 1/5 of 20= 4
So one parcel is 4 books
Then you can set up an equation 16=4x where x = number of parcels.
4x = 16
4x/4 = 16/4
x=4

Security A rounds every 2 minutes and 20 seconds in the gate 1. Security B
rounds every 1 minute and 40 seconds in the gate 2. If they conduct rounds at
the same time After how many minutes they will rounds together again?
Answers
Answer:
They will do rounds together again in 11 minutes and 40 seconds.
Step-by-step explanation:
Security A rounds every 2 minutes and 20 seconds in the gate 1.
That is, after 2*60 + 20 = 120 + 20 = 140 seconds.
Security B rounds every 1 minute and 40 seconds in the gate 2.
That is, after 1*60 + 40 = 60 + 40 = 100 seconds.
After how many minutes they will rounds together again?
First, we find this is seconds, which is the least common multiple between 140 and 100. Factoring them by prime factors:
140 - 100|2
70 - 50|2
35 - 25|5
7 - 5|5
7 - 1|7
1 - 1
lcm(140,100) = 2*2*5*5*7 = 700 seconds
They will do rounds together again in 700 seconds, which is 11 minutes and 40 seconds.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is nine
times the measure of the first angle. The third angle is 20 more than the second. Let x, y, and z represent the measures of
the first, second, and third angles, respectively. Find the measures of the three angles,
balor
Answers
So angle y and z together add up to the other 162 degrees.
Divide 162 in half to find the “middle”...162/2=81.
Since we were told that the difference between y and z is 20...y would be 10 less than that middle number, and z would be 10 more than it...so y=71, and z=91.
The answers are...
X=18, Y =71, Z=91
