Answer:

253cm²

Step-by-step explanation:

Area of the trapezoid = 1/2(b1+b2)*h

Given

h = 22cm

b1 = 10.5cm

b2 = 12.5cm

Substitute

Area of the trapezoid = 1/2(10.5+12.5)*22

Area of the trapezoid = 1/2(23)*22

Area of the trapezoid =11*23

Area of the trapezoid = 253cm²

Hence the area of the trapezoid is 253cm²

Answer:

10.5 Dozens

Step-by-step explanation:

if each gingerbread man has 3, then you will be able to make 126 gingerbread mans, but you asked for dozens, so 126 gingerbread mans divided by 12, which is a dozen, will equal to 10.5 dozens

Answer:

it would be less than

Step-by-step explanation:

so it would be this <

The magnitude of the number 6.209 is less than the number 6.29 thus the sign of inequality will be < as 6.209 < 6.29.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given numbers,

6.209 and 6.29

Since, 6.209 - 6.29 = -0.081

Thus, 6.209 < 6.29.

Hence "The magnitude of the number 6.209 is less than the number 6.29 thus the sign of inequality will be < as 6.209 < 6.29".

Answer:

$375

Step-by-step explanation:

Answer:

Direct variation, by definition, has the form shown below:

y=kx  

Where k is the constant of proportionality.

Given the information in the problem, you can find k:

7=3k

k=7/3

Now you can find y when x=7 as following:

y=(7/3)x

Substitute values.

y=(7*7)/3

y=49/3

Answer:

Step-by-step explanation:

y = ax² + bx + c

~~~~~~~

(4, - 2), (8, 6), (2, 0)

a(4²) + b(4) + c = - 2

a(8²) + b(8) + c = 6

a(2²) + b(2) + c = 0

16a + 4b + c = - 2 .............. (1)

64a + 8b + c = 6 ............... (2)

4a + 2b + c = 0 ................. (3)

a = 0.5 ; b = - 4 ; c = 6

y = 0.5x² - 4x + 6

Part A: (0, 6), (6, 0)

Part B: (0,6)

Part C: (6, 0)

Part D: [ 4, ∞ )

The quadratic function has the form f(x) = ax² + bx + c, where a, b, and c are non-zero values, and the calculation of the values can be defined as follows:

vertex point of graph function= (4,-2)

points=  (8,6) and (2,0)

Using the formula of a quadratic function:

[tex]y = ax^2 + bx + c[/tex]

putting the value into the above-given formula:

[tex]\to (4, - 2), (8, 6), (2, 0)\\\\\to a(4^2) + b(4) + c = - 2\\\\\to 16 a + 4b + c = - 2.........................(a)\\\\\to a(8^2) + b(8) + c = 6\\\\\to 64a + 8b + c = 6......................................(b)\\\\\to a(2^2) + b(2) + c = 0\\\\\to 4a + 2b + c = 0................................(c)\\\\[/tex]

Computing the value of a,b, and c:

[tex]\to a = 0.5\\\\ \to b = - 4 \\\\ \to c = 6\\\\[/tex]

Putting the value of a, b, and c values into the quadratic function:

[tex]\to y = 0.5x^2 - 4x + 6[/tex]

So, the calculated points are:

Part A: (0,6)

Part B: (2,0) and (6,0)  

Part C: x>4

Part D: positive the parabola upwards

Answer:

[tex]7[/tex]

Step-by-step explanation:

This means that there are 20 terms in between 11 and 31

[tex]31-11=20[/tex]

Since we know that the [tex]11th[/tex] term is [tex]29[/tex] and the [tex]31st[/tex] term is [tex]169[/tex], you can subtract the two to find out the values in between

[tex]169-29=140[/tex]

Now all we have to do is divide the values in between by the number of terms to find the common difference.

[tex]\frac{140}{20} =7[/tex]

Therefore the common difference is  [tex]7[/tex]

Step-by-step explanation:

x²+2x+1

x²+x+x+1

x(x+1)1(x+1).

(x+1)(x+1)

x=-1. , x=-1

Answer:

[tex]\displaystyle \boxed{\text{\sf \Large x=-1}}[/tex]

Step-by-step explanation:

Add 1 to both sides

[tex]x^2+2x+1=0[/tex]

Use quadratic formula with a=1, b=2, c=1

[tex]\displaystyle x=\frac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

[tex]\displaystyle x= \frac{-(2) \pm \sqrt{(2)^2-4(1)(1)} }{2(1)}=-1[/tex]

Answer:

sup(x,3)

Step-by-step explanation:

Linear equation:

A linear equation has the following format:

[tex]y = ax + b[/tex]

In a linear equation, when x changes by 1, y will always change by the amount a, which is called slope.

In this question:

y=sup(x,3)+2x+1

[tex]y = 2x + 1[/tex] would be a linear equation.

However, the expression sup(x,3), that is, the higher value between x and 3, means that the function is not linear.

Answer:

Z = 8.4

Step-by-step explanation:

Jusg move 6.3 behind

When something negative moves behind it becomes positive

So 2.1 plus 6.3 is 8.4

Answer:

Z=8.4

Step-by-step explanation:

1. Add 6.3 to both sides.

Z =2.1+6.3

2.Simplify 2.1+6.3 to  8.4

Z=8.4

--------------------------(Checking answer)

Z−6.3=2.1

1. Let Z=8.4

8.4-6.3=2.1

2. Simplify  8.4-6.3 to  2.1

2.1=2.1

Answer:

20 degrees, 50 degrees, 80 degrees, 75 degrees, 60 degrees

Answer:

80 square yards

Step-by-step explanation:

We know we have a width of 8 yards and a perimeter of 36.

how I figured it out was:

36=(8*2) * (x*2)

8*2=16

36-16=10

So now we know the length and width.

area of a rectangle is lw (length * width)

10*8=80.
