The area of the shaded region is [tex]47.5cm^2[/tex].

The area of the shaded region is the area of the whole region minus the area of the unshaded region.

The area of the whole region is equal to the area of the rectangle as a triangle is inscribed in a rectangle and the area of the unshaded region is equal to the area of the triangle.

Then the area of the shaded region will be the area of the rectangle minus the area of the triangle.

The area of the rectangle will be [tex]A_{1}=base\times height[/tex] where the base = 11 cm and height = 5cm.

Then we will get

[tex]A_{1}=11\times5\\A_{1}=55cm^2[/tex]

Now the area of the triangle is [tex]A_{2}=\dfrac{base\times height}{2}[/tex] where the base = 5cm and the height = 3cm.

Then we will get

[tex]A_{2}=\dfrac{5\times3}{2} \\A_{2}=\dfrac{15}{2}\\ A_{2}=7.5[/tex]

Then the area of the shaded region will be [tex]55-7.5=47.5cm^2[/tex].

So, the area of the shaded region is [tex]47.5cm^2[/tex]

Answer:

12 teachers will get 1/2 sheets each

Step-by-step explanation:

Noor bought 21 sheets of stickers

She gave 1/3 sheets to each 45 students

She wants to give teachers 1/2 of sheets

The question should be: how many teachers will she give

Total sheets=21

Students gets= 1/3 × 45

=45/3

=15 sheets

Remaining sheet= total sheets - students sheets

=21-15

=6 sheets

There are 6 sheets remaining for teachers

She wants to give 1/2 to each teacher

Then,

The number of teachers that will get =Remaining sheets ÷ each teacher's share

=6 ÷1/2

Answer:

B. (1/2)(2h-8)(h)

Step-by-step explanation:

Area of a triangle = 1/2 × base × height

Let

Height = h

Base = 8 inches less than 2 times wider than the hight

= 2h-8

Substituting the values of base and height into the formula

We have,

Area of a triangle = 1/2 × base × height

= 1/2 × (2h-8) × h

= (1/2)(2h-8)(h)

The correct answer is option

B. (1/2)(2h-8)(h)

Answer:

Vertical translation of 4 units.

Step-by-step explanation:

If you add 4 to y, you would move up 4 because the y axis is vertical.

Answer:

y = 2x -1

Step-by-step explanation:

y = mx + b

On the y-axis which is the vertical line, it touches the line is on -1.

Therefore, -1 is the y-intercept which is b.

y = mx - 1

Now the slope since it goes up 2 and right one to reach a point again the slope is 2/1 which basically just 2.

Now y = 2x - 1

14.5

Step-by-step explanation:

You would plug 5 into the equation for m and have w = 1.5 (5) + 7

Then you would multiply 1.5 and 5 and get 7.5 and then add 7 and get 14.5

The weight of the baby in pounds at 5 months of age is 14.5 pounds.

Given,

The weight in pounds of a baby in the first six months of life can be modeled by the function:

w = 1.5m +7, where x is the age of the baby in months.

According to this model, we need to find what is the weight, in pounds, of a baby at 5 months of age.

A function has an input and an output.

Example:

f(x) = x + 1

x = 1, f(1) = 1 + 1 = 2

Here,

x = 1 is the input and 2 is the output.

We have,

Function:

w = 1.5m + 7

We can consider that m = number of months.

This is why the question says this model can be used to find the weight of the baby in the first six months by putting m = 6.

w = 1.5m + 7

Here,

7 = the weight of the baby at birth

1.5m = baby weight increases by 1.5 per month.

Now,

The weight in pounds of the baby at 5 months of age is:

m = 5 months

w = 1.5 m + 7

w = 1.5 x 5 + 7

w = 7.5 + 7

w = 14.5 pounds.

Thus the weight of the baby in pounds at 5 months of age is 14.5 pounds.

Answer:

0.02 is different from 0.002 because 0.02 is greater than 0.002

0.02 and 0.002 are the same because they are both decimal numbers

Step-by-step explanation:

0.02 = 2 / 100

0.002 = 2 / 1000

0.02 < 0.002

0.02 is different from 0.002 because 0.02 is greater than 0.002

0.02 can also be written as 2 × 10^2

0.002 can also be written as 2 × 10^3

0.02 and 0.002 are the same because they are both decimal numbers

================================================

Work Shown:

[tex]a \bowtie b = a + \sqrt{b+\sqrt{b+\sqrt{b+...}}}\\\\7 \bowtie g = 7 + \sqrt{g+\sqrt{g+\sqrt{g+...}}} = 9\\\\\sqrt{g+\sqrt{g+\sqrt{g+...}}} = 2[/tex]

After subtracting 7 from both sides.

Note how because we have an infinite sequence of nested radicals, we can let [tex]x = \sqrt{g+\sqrt{g+...}}[/tex] which means x is equal to 2 as well.

This lets us say

[tex]\sqrt{g+\sqrt{g+\sqrt{g+...}}} = \sqrt{g+x} = x[/tex]

Solve the equation [tex]\sqrt{g+x}= x[/tex] for x to get

[tex]\sqrt{g+x} = x\\\\g+x = x^2\\\\x^2-x-g = 0\\\\x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-1)\pm\sqrt{(-1)^2-4(1)(-g)}}{2(1)}\\\\x = \frac{1\pm\sqrt{1+4g}}{2}\\\\x = \frac{1+\sqrt{1+4g}}{2} \ \text{ or } \ x = \frac{1-\sqrt{1+4g}}{2}[/tex]

Since x is positive, this means we only focus on the first equation in the last line above.

Earlier we let x be equal to the infinite nested radicals involving g, but x is also equal to 2. So plug in x = 2 and use that to find g.

[tex]x = \frac{1+\sqrt{1+4g}}{2}\\\\2 = \frac{1+\sqrt{1+4g}}{2}\\\\4 = 1+\sqrt{1+4g}\\\\3 = \sqrt{1+4g}\\\\9 = 1+4g\\\\1+4g = 9\\\\4g = 8\\\\g = 2\\\\[/tex]

As a check, we can do the following

[tex]7 + \sqrt{2+\sqrt{2}} \approx 8.84775906502258\\\\7 + \sqrt{2+\sqrt{2+\sqrt{2}}} \approx 8.96157056080647\\\\7 + \sqrt{2+\sqrt{2+\sqrt{2+\sqrt{2}}}} \approx 8.9903694533444\\\\[/tex]

we're slowly approaching 9

Answer: [tex]g = \boxed{2}[/tex]

Step-by-step explanation:

[tex]\sqrt{g+\sqrt{g+\sqrt{g+...}}}=2[/tex]

implies that

[tex]\sqrt{g+\sqrt{g+\sqrt{g+...}}}=\sqrt{g+2}=2[/tex].

Squaring both sides of this new equality, we have [tex]g + 2 = 4 \implies g = \boxed{2}[/tex]

Step-by-step explanation:

Given that:

Width(w) of rectangular paintball must be = 34 meters

Perimeter of atleast 140m but not more than 260 meters

Perimeter of a rectangle (p) : 2 (l + w)

P = 140

Then ;

140 = 2(l + 34)

140 = 2l + 68

140 - 68 = 2l

72 = 2l

l = 72/ 2 = 36 meters

P = 260

260 = 2(l + 34)

260 = 2l + 68

260 - 68 = 2l

192 = 2l

l = 192/ 2 = 96 meters

Hence the length must be between 36 meters and 96 meters

1+4=5

Given that :-

To Find :-

Solution :-

The fist expression x + y < 5 states that sum of x and y could be any rational number less than 5 .

And the second expression 3 < x < 5 states that value of x could be any rational number between 3 and 5.

Let's check which option suits best.

Is it possible to have value of 8/3 by y ?

→ x + 8/3 < 5

→ x < 5 - 8/3

→ x = 7/3

7/3 is a rational number . So y as 8/3 is possible value.

→ 7/3 = 2.33

But value of x should be greater than 3 .

So option A is wrong.

Is it possible to have value 2 by y ?

→ x +2 < 5

→ x < 5-2

→ x < 3 .

But value of X should be greater than 3.

So option B is also incorrect.

Is it possible to have value 0 by y?

→ x +0 <5

→ x < 5

It also fullfill 2nd expression that X should have value less than 5 and greater than 3.

So option C is valid .

Value of y is 0 .

Step-by-step explanation:

A randomized block design is one where the sample or subjects of the experiment are split into groups called blocks of experimental units where the variation in each block is lower than the variation among or between blocks, such that variation is controlled. In a random order, the treatments are performed on each experimental of the blocks.

In the question, the experimental units are grouped by gender and the treatment (consumption of chocolate or placebo) is randomly administered to the experimental units.

Answer: (14.5cm, 15.4cm)

Step-by-step explanation:

We have a measure of 15cm.

This may be a rounded up or rounded down number.

Now, when we want to round at a given digit, we need to see to the previous digit.

If the previous digit is larger than 5, then we round up.

If the previous digit is 5 or smaller, then we round down.

Then, the largest number such that we rounded down to 15cm, is:

15.4cm

The smallest number such that we rounded up to 15cm is:

14.5cm

Then the range of possible values is:

Solution:

we also have given the length of ribbon-

[tex]7 \: cm[/tex]

and, width-

[tex]y \: cm[/tex]

so, area of the ribbon is-

length×width

[tex]7 \times y \: cm^{2} \\ 7y \: cm^{2} [/tex]

now the area of shaded gray region will be-

[tex]7x + 35 - 7y[/tex]

Hence, the required expression would the above expression.

Answer: 29

Step-by-step explanation:

Given : Total people in the line = 35

Number of people behind Amy = 15

⇒Number of people in front of Amy   = Total people - (Amy and people behind Amy)

= 35-15-1

= 19

According to the question,

Number of people in front of Amy + Number of people behind Jed =24

⇒ 19 +  Number of people behind Jed =24

⇒  Number of people behind Jed =24 -19 = 5

Then, Number of people are in front of Jed = 35 - (Jed and people behind Jed)

= 35-(5+1)

= 35-6=29

Hence, there are 29 people are in front of Jed.
