Step-by-step explanation:

because all four sides of a rectangle don't have to be equal. However, the sets of rectangles and rhombuses do intersect, and their intersection is the set of squares—all squares are both a rectangle and a rhombus.

Answer:

∠ B = 80.5°

Step-by-step explanation:

Since AB = AC then the triangle is isosceles with base angles congruent, so

∠ B = ∠ C , then

∠ B = [tex]\frac{180-19}{2}[/tex] = [tex]\frac{161}{2}[/tex] = 80.5°

Answer:

The multiplicity of the root is 1

Step-by-step explanation:

Firstly, we need to understand what multiplicity is

By multiplicity, we simply refer to the number of times we have the certain root repeating itself

From the factorization, each of the given roots were only repeated once

That indicates that the given multiplicity is 1

Hello again, hehelol12.

PQ is equal to CB. So the length of PQ must be 9.

Angle PQR is equal to CBA. Therefore the measure of angle PQR is 46.

I hope this helps!

Step-by-step explanation:

since they are congruent triangles, all your have to done is the compare the longest side of the first triangle is equal to that of the other; the smallest side of the first triangle is equal to that of the second, and so for the corresponding angles

using the above method,

Answer:

a) from mere observation line PQ is the longest therefore it is equal to the length of the longest side of the other triangle. so line PQ = 9

b) again, ang PQ is the smallest, using the method, ang PQ = 46 degrees

but mind you, you could use a ruler to measure the length to find the longest more accurately.

Answer: $1,467.80

Step-by-step explanation:

The formula for the future value given annual compounding is:

= Amount * ( 1 + rate) ^ number of years

The amount after 3 years at 5.5% is therefore:

= 1,250 * ( 1 + 5.5%)³

= 1,250 * 1.174241375

= $1,467.80

Answer:

Length of Rectangle is 3 cm less than twice the width

Area is 44 m2 ; let W = width;  2W - 3 = Length

Arect = L times W

44 = W ( 2W - 3 )

44 = 2W2 - 3W

0 = 2W2 - 3W - 44

Factoring

0 = ( 2W - 11 )( W +4)

2W - 11 =0   ;            W + 4 = 0

       W = 11/2                 W = -4  (width can not be a negative number)

Therefor: width is 11/2  and length is 8

By Set theory, 420 many people in the survey use brand P and not brand Q.

What is Set theory?

The mathematical concept of sets, which are well-defined collections of things that are referred to as their members or elements, is known as set theory. As only sets are the subject of pure set theory, the only sets that are taken into account are those whose members are also sets.

                               The major reason why set theory is significant is because it offers the axioms upon which the rest of mathematics is constructed. We study sets and their characteristics in the area of mathematical logic known as set theory. A collection of items or a group of items is referred to as a set. These items are frequently referred to as elements or members of a set.

P use = 630 people

Q use = 420 people

both P&Q use ie P∩Q = 210 People

use brand P but not brand Q = P/ P∩Q

                                               = 630 - 210

                                             = 420

Step-by-step explanation:

Answer:

the first one

Step-by-step explanation:

Answer:

( 9 - 4 ) - 5

Step-by-step explanation:

According to the scenario, expressions can be written as follows,

Subtract is denoted by (-) sign.

So, First sequence of operation,

= For subtract 4 from 9 can be written as ( 9 - 4)

= Second sequence of operation,

Now, subtract 5 from result can be written as ( 9 - 4) - 5

Hence, the final written expression will be ( 9 - 4) - 5.

the formula is a^2+b^2=c^2

A and B are the sides doesn't matter which

C is always across from the right angle

so fill x in accordingly

4^2+3^2=x^2

16+9=

25= x^2

square root both 25 and x^2

25 becomes 5

x^2 becomes x

x=5

and just apply this to the other problems

Answer is D) 42x − 24

Step-by-step explanation:

Opening the expression given in question

6(7x − 4)

6 will be multiplied by both items present inside parenthesis.

it can be written as

={(6 * 7x) - (6*4)}

=42x-24

Hope that clears the question.

im not sure i think its 14.2

x²+2x-15=(x+5)(x-3) there is nothing to factoriz

Answer: The value of x is 6.

Step-by-step explanation:

In the figure we have two secants.

A secant is a line that intersects a circle in exactly two points.

For the figure attached below:

[tex]a\times b=c\times d[/tex]

So for the given figure,

[tex]x\times 8=4\times (4+8)\\\\\Rightarrow\ x=\dfrac{4\times12}{8}\\\\\Rightarrow\ x=6[/tex]

Hence, The value of x is 6.

Answer:

2/9

Step-by-step explanation:

Find the slope of the line with x intercept 9 and y intercept of -2

Given that the equation of the line is y = mx+b

x intercept occurs when y = 0

The coordinate of x intercept is (9,0)

y intercept occurs at x = 0

The coordinate of y intercept is (0, -2)

Slope m = y2-y1/x2-x1

m = -2-0/0-9

m = -2/-9

m = 2/9

Hence the required slope is 2/9

12. option 1

Step-by-step explanation:

Answer:

x = 7 , y = 3 , or 7 free throws, and 3 3-pointers.

Step-by-step explanation:

James scored a total of 16 points during a basketball. Only free throws and 3-point baskets are used. Free throws = 1 point (x), 3-pointers = 3 points (y).

Set the equations:

16 = x + 3y

10 = x + y

First, isolate the variable x in the second equation. Divide y from both sides of the equation:

10 (-y) = x + y (-y)

x = 10 - y

Next, plug in 10 - y for x in the first equation:

16 = x + 3y

16 = (10 - y) + 3y

Simplify. Combine like terms:

16 = 10 - y + 3y

16 = 10 + (-y + 3y)

16 = 10 + 2y

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, subtract 10 from both sides of the equation:

16 (-10) = 10 (-10) + 2y

2y = 16 - 10

2y = 6

Next, divide 2 from both sides:

(2y)/2 = (6)/2

y = 6/2 = 3

Plug in 3 for y in one of the equations:

16 = x + 3y

16 = x + 3(3)

16 = x + 9

Isolate the variable, subtract 9 from both sides of the equation:

16 (-9) = x + 9 (-9)

x = 16 - 9

x = 7

x = 7 , y = 3 , or 7 free throws, and 3 3-pointers.

Plug in to check:

16 = x + 3y

10 = x + y

16 = (7) + 3(3)

16 = 7 + 9

16 = 16 (True)

10 = (7) + (3)

10 = 10 (True).

x = 7 , y = 3  or 7 free throws, and 3 3-pointers.

Answer:

x = 11

Step-by-step explanation:

The given angles are supplementary which means their sum is 180

8x - 6 + 98 = 180 add like terms

8x + 92 = 180 subtract 92 from both sides

8x = 88 divide both sides by 8

x = 11
