2nd answer

Check your work:

16+22=38

It is correct.

Answer:

66 & -28

Step-by-step explanation:

x > y

x + y = 38

x = 10 - 2y

10 - 2y + y = 38

-y + 10 = 38

-y = 28

y = -28

x + (-28) = 38

Based on data from 2011-2012, the percentage of 6- to 11-year-olds who were obese was about _____ than the percentage of two- to five-year-olds who were obese.

Answers

Using the percentage concept, it is found that the percentage of 6- to 11-year-olds who were obese was about 17.76% more than the percentage of two- to five-year-olds who were obese.

What is a percentage?

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

[tex]P = \frac{a}{b} \times 100\%[/tex]

Researching on the internet, we find that:

The percentage of two-to-five year old who are obese is of a = 15.2%.The percentage of 6-to-11 year old who are obese is of b = 17.9%.

Hence:

[tex]P = \frac{17.9}{15.2} \times 100\% = 117.76\%[/tex]

117.76% - 100% = 17.76%.

Hence the percentage of 6- to 11-year-olds who were obese was about 17.76% more than the percentage of two- to five-year-olds who were obese.

What is the product of the complex numbers (-3i+4) and (3i+4)?

Answers

Answer: 25

Step-by-step explanation:

Finding the product of complex numbers is not different to finding the product of real numbers

(-3i+4) * (3i+4) = -9i^2 + 12i - 12i + 16 = 25

Answer:

25

Step-by-step explanation:

An easy way to multiply binomials is the FOIL(first, outer, inner, last) method. Multiply the first terms of each binomial, -3i×3i=-9i^2. Then do the outer terms, -3i×4=-12i. Then do the inner terms 4×3i=12i. Then do the last terms, 4×4=16. Lastly combine like terms, the -12i and 12 cancel out, and you're left with -9i^2+16. i^2=1, so then you get -9(-1)+16. -9×-1=9. 9+16=25

5-3=2

3+2+5=10

The house number if the house number is a three-digit number, it is a multiple of 5. There are no zeros in this number, is 235.

What is equation?

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given:

A house number is a three-digit number.it is a multiple of 5,

The number in the hundreds place is two less than the number in the one's place,

The sum of the digits is 10,

Write the equation as shown below,

x + y + z = 10

Here x is in one place y is in the tens place and z is in the hundred places,

The number will be = 100z + 10y + x

y = x - 2

As we know if the number is a multiple of 5 then its one's place is either 0 or 5 here no zeroes in the number,

x = 5,

y = 5 - 2 = 3

z = 10 - 3 - 5

z = 2

Thus, the number will be,

Room number = 100 × 2 + 10 × 3 + 5

Room number = 200 + 30 + 5

Room number = 235

Step-by-step explanation:

Rewrite the function in the slope-intercept form:

y - 3 = 3xy = 3x + 3

The ordered pairs:

x = 0 ⇒ y = 3 ⇒ (0, 3)x = 1 ⇒ y = 6 ⇒ (1, 6)x = 2⇒ y = 9 ⇒ (2, 9)x = 3 ⇒ y = 12 ⇒ (3, 12)

9. The ability of do work hard is inversely proportional to age of man after youngness to onward.

10.  The number of mistake in work is inversely proportional to practice.

Explanation:

Direct Variation: A relationship where one quantity is a constant multiplied by another quantity is called direct variation.

Inverse Variation: Inverse variation is defiend as the relationship between two variables in which the resultant product is a constant. If a is inversely proportional to b, the form of equation is a = k/b, where k is constant. Inverse variation is known as the opposite of direct variation. If there an increas ein one variable, the other variable decreases in proportion so that the resultant product remains unchanged.

A ship has an island directly in the path of the destination port, so it has to travel 11.5 miles west and then 8.4 miles north to get to the port. To the nearest tenth,how much shorter would the trip be if the ship could go directly to port?

Answers

Answer:

Step-by-step explanation:

The direct distance there (without the island in the way) is found using the Pythagorean Theorem

c^2 = a^2 + b^2

a = 8.4

b = 11.5

c = ?

c^2 = 8.4^2 + 11.5^2              Square the length of the legs.

c^2 = 70.56 + 132.25            Combine  

c^2 = 202.81                          Take the square root.

c = 14.24

But the island is there. The distance travelled = 8.4 + 11.5 = 19.9 miles

So the additional distance = 19.9 - 14.24 = 5.66 miles.

One equation in a system of equations is given in the graph. Which equation below would have to be the second equation so that the system has no solutions?

Answers

Solution:

To classify the system of equations as no solutions, the lines must be parallel (Not intersect).

First, let's identify the equation forming the line.

Slope = Rise/Run = 2/-3 = -0.66Y-intercept = 0Equation formed: y = -2/3

We also know that the slope of the equation must be -1.5.

A) 2x + 3y = 0

3y = 0 - 2x=> 3y = -2x=> (y = -2x/3) ∦ (y = -2x/3)

B) 2x + 3y = 6

=> 3y = -2x + 6=> (y = -2x/3 + 2) ║ (y = -2x/3)

C) 2x - 3y = 9

=> -3y = -2x + 9=> y = -2x/-3 + 9/-3=> (y = 2x/3 - 3) ∦ (y = -2x/3)

D) y = 3x + 2

(y = 3x + 2) ∦ (y = -2x/3)

Option B is correct.

help on 5 . find the value of x

Step-by-step explanation:

The angle in the figure is 90°

[tex]36 + (11x - 1) = 90 \\ 36 + 11x - 1 = 90 \\ 11x + 35 = 90 \\ 11x = 90 - 35 \\ 11x = 55 \\ \\ x = \frac{55}{11} \\ \\ x = 5[/tex]

To find the value of x, we can set an equation like: 36 + 11x - 1 = 90
Combining like terms gets us to 35 + 11x = 90
Subtract 35 from both sides and divide by 11 to get
x = 5

Find the area of each shaded region

Answers

[tex]\bold{\huge{\blue{\underline{ Solution }}}}[/tex]

Given :-

The radius of the circle is 5 units

To Find :-

We have to find the area of shaded region .

Let's Begin :-

The given figure is composed of two figures triangle and circle. In which triangle is enclosed in the circle.

The triangle is the unshaded region of the given figure

We know that,

Area of triangle

[tex]\bold{\red{ = }}{\bold{\red{\dfrac{1}{2}}}}{\bold{\red{\times{ Base }}}}{\bold{\red{\times{ height }}}}[/tex]

Here,

The base of the triangle is equal to the diameter of the circle that is, [tex]\sf{ Base = 5 + 5 = 10 \: units }[/tex]The height of the triangle is equal to the radius of the triangle that is[tex]\sf{ Height = 5 \:units }[/tex]

Subsitute the required values,

Area of the given triangle

[tex]\sf{ = }{\sf{\dfrac{1}{2}}}{\sf{\times{ 10 }}}{\sf{\times{ 5 }}}[/tex]

[tex]\sf{ = 5 }{\sf{\times{ 5}}}[/tex]

[tex]\bold{ = 25\: units }[/tex]

Thus, The area of triangle is 25 units

Now

We have to find the area of the circle

The radius of the circle is 5 units

We know that,

Area of circle

[tex]\bold{\pink{ = }}{\bold{\pink{\pi{r^{2}}}}}[/tex]

Subsitute the required values,

[tex]\sf{ = }{\sf{\pi{(5)^{2}}}}[/tex]

[tex]\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{ 25}}}[/tex]

[tex]\sf{ = }{\sf{\dfrac{550}{7}}}[/tex]

[tex]\bold{ = 78.57\: units }[/tex]

Thus, The area of circle is 78.57 units

Therefore,

Area of shaded region

= Area of circle - Area of triangle

Subsitute the required values,

[tex]\sf{ = 78.57 - 25 }[/tex]

[tex]\bold{\green { = 53.57 \: units }}[/tex]

Hence, The area of shaded region is 53.57 units.

The area of the shaded figure is 13.375 square units.

What is the area of the shaded region?

The shaded region is a circle with a triangle inside of it removed.

To get the area, we need to get the area of the circle and remove the area of the triangle.

Remember that for a circle of radius R, the area:

A = 3.14*R^2

In this case, we can see that the diameter of the circle measures 5 units, then the radius (half of the diameter) measures 2.5 units.

A = 3.14*(2.5)^2 = 19.625 square units.

And a triangle of base B and height H has an area:

A' = B*H/2

In this case, the base of the triangle is equal to the diameter of the circle, and the height is equal to the radius of the circle, so we have:

B = 5 units.

H = 2.5 units.

Then:

A' =5*2.5/2 = 6.25 square units.

Then the shaded area is:

shaded area =  19.625 square units -  6.25 square units.

                     = 13.375 square units.

Can u help me and give me the solution. I have rsm tomorrow! please and thanks. find x

Answers

Answer: 25°

Step-by-step explanation: Notice that in this figure, we are given two triangles and to find the value of x, we first need to find the missing angle measure in the big triangle.

Since all the interior angles of a triangle add up to 180 degrees, we know that the missing angle of the big triangle is 180° - 94° - 41° or 45°.

Now we know all the angles of the big triangle and we know two of the angles of the smaller triangle, so we can find the value of x.

The missing angle of the smaller triangle will be 180° - 110 - 45° or 25°

So we know that the missing angle is 25°.
