If x = 34, y = 53, and the measure
of AC = 4 units, what is the difference in length between
segments AB and AD? Round your answer to
the nearest
hundredth.
A- 0.74
B- 1.17
C- 1.64
D- 2.14
9514 1404 393
Answer:
D 2.14
Step-by-step explanation:
The lengths of interest are the hypotenuses of the respective triangles. We are given the angle and the opposite side, so the sine relation is of interest.
Sin = Opposite/Hypotenuse
sin(34°) = AC/AB ⇒ AB = AC/sin(34°)
sin(53°) = AC/AD ⇒ AD = AC/sin(53°)
The desired difference in lengths is ...
AB -AD = AC(1/sin(34°) -1/sin(53°)) = 4(1.78829 -1.25214) ≈ 2.1446
The difference in lengths is about 2.14 units.

To prepare for a bake-off, Luis used 590 grams of flour each day for 3 weeks. How many kilograms did Luis use in those 3 weeks? 1 g = 0.001 kg Solve this on paper. Then check your answer on Zearn. Luis used kilograms of flour in 3 weeks.
Answer: [tex]12.39\ kg[/tex]
Step-by-step explanation:
Given
Luis used 590 gm of flour each day
If he continues to use it for 3 weeks
A week has 7 days; so 3 weeks have 21 days
The flour used in 21 days
[tex]\Rightarrow 21\times 590\\\Rightarrow 12,390\ g\ \text{or}\ 12.39\ kg[/tex]
Thus, [tex]12.39\ kg[/tex] of flour is used in 3 weeks

A parallelogram has vertices at (-5, -1), (-2, -1), (-3, -4), and (-6, -4). What is the approximate perimeter of the parallelogram? Round your answers to the nearest hundredth.
A. 9.16
B. 12 units
C. 12.32 units
D. 14
Answer:
12.32 units
Step-by-step explanation:
Use the distance formula to find the lengths between two points:
[tex]d=\sqrt{(x_{2} -x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
the distance between (-2, -1) and (-5,-1) is
[tex]\sqrt{(-2-(-5))^2+(-1-(-1))^2}[/tex]
=[tex]\sqrt{3^2+0^2}[/tex]
=[tex]\sqrt{9}[/tex]
=3
the distance between (-2, -1) and (-3, -4) is
[tex]\sqrt{(-2-(-3))^2+(-1-(-4))^2}[/tex]
=[tex]\sqrt{1^2+3^2}[/tex]
=[tex]\sqrt{10}[/tex]
≈3.16
the distance between (-6, -4) and (-3, -4) is
[tex]\sqrt{(-6-(-3))^2+(-4-(-4))^2}[/tex]
=[tex]\sqrt{(-3)^2+0^2}[/tex]
=[tex]\sqrt{9}[/tex]
=3
the distance between (-6, -4) and (-5, -1) is
[tex]\sqrt{(-6-(-5))^2+(-4-(-1)^2}[/tex]
=[tex]\sqrt{(-1)^2+3^2}[/tex]
=[tex]\sqrt{10}[/tex]
≈3.16
Now, add all the sides:
3+3.16+3+3.16=12.32 units
Note: A property of a parallelogram is that it has two pairs of congruent sides, so for this problem, you could solve for 2 different sides, double them, then add and you will get the same thing.

Answer:
a) -1535.5
b) 0
Step-by-step explanation:
A) We do this problem according to its parenthesis. First, let's evaluate the first half, -2[(-1/4)-12(-1)^2]. We have to do (-1)^2 first, because of PEMDAS. (-1)^2 is just 1. Now, our equation is -2[(-1/4)-12*1]. Thus, we get -2[(-1/4)-12] because 12*1 is just 12. Then, we do (-1/4)-12, giving us -12.25. Our equation becomes -2(-12.25). Then, we just get 24.5.
The next half, -5[24+2(-12)^2] is similar. We first evaulate (-12)^2 because of PEMDAS, giving us 144. Then, we have -5[24+2(144)]. 2 times 144 is 288, so we get -5[24+288]. 24 + 288 is 312, so we have -5(312). This finally gives us -1560.
Putting the two together, we get 24.5 - 1560, which is -1535.5.
--------------------------------------------------------------------------------------------------------------B) We substitute a = -1/3 and b = -1 into the equation, -a^2b^2 - 3a^3b^2.
We plug in -1/3 where a is and -1 where b is. So:
-(-1/3)^2(-1)^2 - 3(-1/3)^3(-1)^2.
The tricky part of this problem is making sure you follow PEMDAS. We evaluate the exponents first.
-1/9 * 1 - 3(-1/27) * 1
= -1/9 + 1/9
= 0

Find the complement and supplement of 73°:
Answer:
The complement of 73° is 17°
The supplement of 73° is 107°
Step-by-step explanation:
Two angles in a complementary are equal to 90°
∴ For complementary:
73° + x = 90°
x = 90°- 73°
∴ x = 17 °
Two angles in a supplementary are equal to 180°
∴ For supplementary:
73° + x = 180°
x = 180° - 73°
∴ x = 107°

Identify the simplest polynomial function having integer coefficients with the given zeros. 0,-4,√3.
A. P(x) = x^4 + 4x³ - 3x² -12x
B. P(x) = x^4 + 4x³ -12x² - 3x
C. P(x) = x³ + 4x² - 12x - 3
D. P(x) = x³ + 4x² - 3x - 12
Answer:
x^4+x^3-3x^2-12x
Step-by-step explanation:
0,-4,√3 are the zeros of polynomial. P.
If x=√3 is a zero and P has integer coefficients, then x=-√3 is also a zero. Both of these results come from solving the equation x^2=3 or x^2-3=0 so x^2-3 is a factor of P.
x=0 is a zero, means x-0 or x is a factor.
x=-4 is a zero, means x-(-4) or x+4 is a factor.
So the polynomial, P, in factored form is
x(x^2-3)(x+4)
Let's write in standard form.
I will begin by multiplying the last two factors.
x(x^3+x^2-3x-12)
Distribute x

area of a circle of radius is 6.5?
Answer:
see below
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
A = pi (6.5)^2
A =42.25 pi
If we approximate pi by 3.14
A = 42.25 * 3.14 =132.665
If we use the pi button
A = 132.7322896

work out the size of angle x
ill mark brainliest first corect answer!
Answer:
65°
Step-by-step explanation:
First we find the sizes of the other two sides, as the bottom line is straight all angles on it must add up to 180 so:
180-105=75
So the first angle is 75°
180-140=40
So the second angle is 40°
Now as the angles of a triangle add up to 180 we can derive this equation:
75+40+x=180
and all we do is just subtract both sides by 75 and 40:
x=180-75-40
x=65
And 65 is our answer

Use technology or a z-score table to answer the question.
The amount spent by customers at a grocery store is normally distributed with a mean of $144.05 and a standard deviation of $34.52.
Approximately what percent of customers at the grocery store spend more than $200?
5.3%
8.2%
91.8%
94.7%
Answer:
5.3%
Step-by-step explanation:
The first step is to find the z score corresponding to $200.
[tex]z=\frac{x-\mu}{\sigma}\\\\z=\frac{200-144.05}{34.52}\approx 1.62[/tex]
The next step is to find the area under the standard normal curve to the right of z = 1.62. Some graphing calculators can do this, and there are tables that will help, although many of those show areas to the left of a particular z-score.
Calculator (TI-83/84)
See the attached image.
The command uses 1 x 10^99 as "positive infinity" and calculates the area under the normal curve from 1.62 all the way to the right.
Table
See attached table. This table shows areas to the left of a certain z-score.
Find the entry for 1.62 (it's on page 2 highlighted with a red box). The table says the area to the left of 1.62 is 0.9474.
But the area under the entire curve is 1!
This important fact means that the area to the right of z = 1.62 is 1 - 0.9474 = 0.0536, about 5.3%
(To get the area to the right of z, subtract the area to the left of z from 1.)

The height of the building is approximately 24.19 feet.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given that, place a 29-foot ladder against the top of a building and the bottom of the ladder is 16 feet from the bottom of the building.
So, hypotenuse of the triangle is 29 feet and base of the triangle is 16 feet.
Let h be the height of the building.
Now, 29²=16²+h²
841=256+h²
h²=841-256
h²=585
h=24.19 feet
Therefore, the height of the building is approximately 24.19 feet.
