Answer:
B
Step-by-step explanation:
if b and c are complementary that means b + c = 90
b + 47 = 90
b = 43
since a and b are congruent they are equal
if b = 43 then a = 43

Over But not over The tax is
$0 $7,825 10% of the amount over $0
$7,825 $31,850 $788 + 15% of the amount over $7,825
$31,850 $77,100 $4,386 + 25% of the amount over $31,850

$349,700 And Over $101,469 + 35% of the amount over $349,700
Tim Tradesman had a taxable income of $82,500. He figured his tax from the table above.
1. Find his earned income level.
2. Entered the base amount. = $
3. Found the amount over $ = $
4. Multiplied line 3 by % = $
5. Added Lines 2 and 4 = $
Answer:
Tax= $ 7,173.5
Step-by-step explanation:
Her taxable income is $ 43,000 which lies in the tax category $ 31,850 to
$ 77,100.
Tax for $ 31,850 is $ 4,386
Plus 25% of the amount = ( $ 43,000- $ 31,850 )= $ 11,150 over
25 % of $ 11,150= $ 2,787.5
Total Tax= $ 4386 + $ 2787.5= $ 7,173.5

Answer:
7√2
Step-by-step explanation:
The triangle is a "special triangle", an isosceles right triangle. The side lengths of this triangle have the ratios 1 : 1 : √2. Multiplying these ratio values by 7, the length of the leg, you find ...
c = 7×√2
c = 7√2
_____
If you like, you can go through the Pythagorean theorem and/or trigonometry to find the same thing.
7/c = sin(45°)
c = 7/sin(45°) = 7/(1/√2) = 7√2
Or ...
c² = 7² + 7² = 98 . . . . using the Pythagorean theorem*
c = √98 = 7√2
__
* This requires you recognize the triangle is isosceles, so the other leg is also 7. Of course, you know that as soon as you see a 45° acute angle in a right triangle.

Marcus purchased 4 1/2 pounds of rice on Monday and 2 1/3 pounds of rice on Tuesday, What was the total weight, in pounds, of rice purchased by Marcus in the two-day period?
A. 6 1/6
B. 6 2/5
C. 6 1/3
D. 6 5/6
E. 7 5/6
Answer:
he would have bought 6 5/6 pounds of rice.
Step-by-step explanation:
4 1/2 + 2 1/3 = ?
First, you want to get common dominaters. And the closest number is 6
4 3/6 + 2 2/6 = 6 5/6
This can not be simplifyed so that would be your answer.
The total weight, in pounds, of rice purchased by Marcus in the two-day period is [tex]6\frac{5}{6}[/tex] pounds.
Addition of fraction:It is given that,
Amount of rice purchased on Monday = [tex]4\frac{1}{2} pounds[/tex]
Amount of rice purchased on Tuesday[tex]=2\frac{1}{3} pounds[/tex]
the total weight, in pounds, of rice purchased by Marcus in the two-day period is computed as;
[tex]=4\frac{1}{2}+2\frac{1}{3} \\\\=\frac{9}{2} +\frac{7}{3} \\\\=\frac{27+14}{6} \\\\=\frac{41}{6}\\ \\=6\frac{5}{6} pounds[/tex]
Therefore, the total weight of rice is [tex]6\frac{5}{6}[/tex] pounds.

Answer:
D (last one), [tex]x^2+y^2=45[/tex]
Step-by-step explanation:
We need to find the distance between (0,0) and (-3,6). Using the distance formula we get:
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]d=\sqrt{\left(-3-0\right)^2+\left(6-0\right)^2}[/tex]
[tex]d=3\sqrt{5}[/tex]
Since equation of circle is: [tex]x^2+y^2=r^2[/tex] we have to square the distance we just found, which gives us 45.
Answer:
x^2 + y^2 = 45
Step-by-step explanation:
(x − a ) ^2 + ( y − b ) ^2 =r^2
= (-3-0)^(2)+(6-0)^(2)
=45

Answer:
Option 2 (open circle at 6 with arrow going to the right.
Step-by-step explanation:
Open circle means "excluding that number". Since x>6, x cannot be 6 so we have an open circle at 6. x>6 also means x has to be greater than 6, so we have the arrow going to the right since 7 is greater than 6, 8 is greater than 6, and so on so forth.

A ganza is a percussion instrument used in samba music.
a. Find the surface area of each of the two labeled ganzas in terms of π , rounded to the nearest thousandths and as a decimal, round to the nearest whole number.
Surface area of smaller ganza =
π≈
cm2
Surface area of larger ganza =
π≈
cm2
b. The weight of the smaller ganza is 1.1 pounds. Assume that the surface area is proportional to the weight. What is the weight of the larger ganza to the nearest tenth of a pound?
The weight of the larger ganza is about
pounds.
Answer:
1036.2 sq. cm
Step-by-step explanation:
The surface area of the smaller ganza = 2πr2 + 2πrh
surface area = 2 x 3.14 x 3.5 x 3.5 + 2 x 3.14 x 3.5x 10
surface area = 76.93+ 219.8
surface area = 296.73 sq. cm
The surface area of the larger ganza = 2πr2 + 2πrh
surface area = 2 x 3.14 x 5.5 x 5.5 + 2 x 3.14 x 5.5x 24.5
surface area = 189.97+846.23
surface area = 1036.2 sq. cm
a. The surface area of the smaller ganza is [tex]296.73cm^{2}[/tex]
The surface area of the larger ganza is [tex]1036.2cm^{2}[/tex]
b. The weight of the larger ganza is [tex]3.84[/tex] pounds.
Surface area :From given figure,
Radius of smaller ganza ,[tex]r_{1}=3.5/21.75cm[/tex]
height of smaller ganza, [tex]h_{1}=10cm[/tex]
a. The surface area of the smaller ganza is,
[tex]S_{1}= 2 \pi r^{2} + 2\pi rh[/tex]
[tex]S_{1}=2 * 3.14 * 3.5 * 3.5 + 2 * 3.14 * 3.5* 10\\\\S_{1}=76.93+ 219.8\\\\S_{1}=296.73cm^{2}[/tex]
The surface area of the larger ganza
[tex]S_{2}= 2\pi r^{2} + 2\pi rh[/tex]
[tex]S_{2}= 2 * 3.14 * 5.5 * 5.5 + 2 * 3.14 * 5.5* 24.5\\\\S_{2}= 189.97+846.23\\\\S_{2} = 1036.2 cm^{2}[/tex]
b. Since, the surface area is proportional to the weight.
and The weight of the smaller ganza is 1.1 pounds.
[tex]\frac{1.1}{w}=\frac{296.73}{1036.2}\\ \\ w=\frac{1036.2*1.1}{296.73}\\ \\w=3.84[/tex]

Make a conjecture of what the x-intercepts of the function
f(x) = (2x - 1)(x + 3) will be.
Answer:
x=-3,x1/2
Step-by-step explanation:
f(x)=(2x-1)(x+3)
TI find x intercept/zero substitute
f(x)=0
0=(2x-1)x(x+3)
swap the sides of the equation
(2x-1)x(x+3)=0
when the product of factors equals 0,at least one factor is zero
2x-1=0
x+3=0
solve the equation for x
x=1/2
x+3=0
solve the equation of x
x=-3
The equation has two solution
x=-3
x=1/2

EXPLAIN why the solution to the absolute value inequality | 4x - 9 | ≥- 12 is all real numbers.
Answer:
no matter what value you substitute for x, the absolute value will force the result to be a positive number and any positive number is greater than -12
Answer: Since the absolute value of any number is always greater than or equal to zero, then the given inequality holds for every real number.
Explanation: It doesn't matter which number you substitute for x, as the absolute value will convert the number into a positive one, which will always be greater or equal to 0. Hence, every real number can be a possible answer.
