Answer:

87.5

Step-by-step explanation:

The area of the deck is 87.5 square feet.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

The given figure, can be divided into two triangles and 1 rectangle.

Here, area of a triangle = 1/2 ×Base×Height

= 0.5×5×3

= 7.5 square feet

Area of right triangle = 1/2 ×5×10

= 25 square feet

Area of a rectangle = Length×Breadth

= 11×5

= 55 square feet

Total area = 55+25+7.5

= 87.5 square feet

Therefore, the area of the deck is 87.5 square feet.

Answer:

degree 3

Step-by-step explanation:

The degree of a polynomial is determined by the largest exponent of the term within the polynomial.

4x²y = 4x²[tex]y^{1}[/tex] ← with exponent 2 + 1 = 3

x² ← exponent 2

- 2y² ← exponent 2

The term with the largest exponent is 4x²y with exponent 3

Then the polynomial is of degree 3

Answer:

1:4

Step-by-step explanation:

Since the first circle has an area of 50.24 and the second circle is 4 times that, the ratio is 1:4 because for every 50.24 units of the first circle, there are 200.96 units of the second circle (which is 4 times the amount of the first circle).

Answer:

37 inches.

Step-by-step explanation:

Well, we know the formula is a²+b²=c²

So, first plug in leg one and leg two:

12²+35²=c²

Now, solve.

144+1225=c²

1369=c²

Okay, so we have to square root 1369 to find c.

The square root of 1369 is 37.

Therefore, the answer is 37 inches.

the first x < 3 so x could be from - 1 till 3 in this graph

the other x > - 7 so x could be from from - 7 till - 3 in this graph

Answer:

x = 17

Step-by-step explanation:

corresponding interior angles are supplementary, meaning they have to add up to 180 degrees so

6x + 8 + 4x + 2 = 180°     then combine like terms ( 6x and 4x, 8 and 2 )

10x + 10 = 180         subtract 10 from both sides

        -10     -10

10x = 170            divide each side by 10

/10     /10

x = 17

Answer:

a; 3.45 * 10^3

b) 2.34 * 10^18

c) 80%

Step-by-step explanation:

a) 3450 in standard form

To write in standard form, we have to place a decimal at the back of the first non-zero number

we have this as ;

3.450

The count of numbers after the decimal point is 3

This will be the power to which 10 will be raised

We have this as;

3.45 * 10^3

b) 234 * 10^16

Let us write 234 in standard form

That will be;

234 = 2.34 * 10^2

So we have ;

2.34 * 10^2 * 10^16

Using the law of indices, we have;

2.34 * 10^(2 + 16) = 2.34 * 10^18

c) From the question, Kuwait is 4/5 of Hong kong’s population

Let Honk Kong’s population be x

4/5 * x = 2.4 million

4x = 5 * 2.4 million

x = 5 * 2.4/4

x = 5 * 0.6

x = 3 million

so writing the population of Kuwait as a percentage of that of Hong kong, we have

2.4/3 * 100%

= 0.8 * 100% = 80%

Step-by-step explanation:

Given [Missing Information]

[tex]Red = 12[/tex]

[tex]Blue = 10[/tex]

[tex]Green = 15[/tex]

[tex]Yellow = 13[/tex]

Way 1:

Add up the total marbles that are not red.

[tex]Not\ Red = Blue + Green + Yellow[/tex]

[tex]Not\ Red = 10 + 15 + 13[/tex]

[tex]Not\ Red = 38[/tex]

Divide by total marbles to get the probability;

[tex]Probability = \frac{Npt\ Red}{Total}[/tex]

[tex]Probability = \frac{38}{38 + 12}[/tex]

[tex]Probability = \frac{38}{50}[/tex]

[tex]Probability = 0.76[/tex]

Way 2:

Calculate the probability of choosing red

[tex]P(Red) = \frac{Red}{Total}[/tex]

[tex]P(Red) = \frac{12}{50}[/tex]

[tex]P(Red) = 0.24[/tex]

Apply complement rule (i.e. subtract it from 1)

[tex]P(Not\ Red) = 1 - P(Red)[/tex]

[tex]P(Not\ Red) = 1 - 0.24[/tex]

[tex]P(Not\ Red) = 0.76[/tex]

Answer:

x=7

Step-by-step explanation:

The pattern is:  i^1 = i, i^2 = −1, i^3 = −i, i^4 = 1, i^5 = i, i^6 = −1 and repeats again, so x = 7 would be i^20 = [tex](i^{4} )^{5}[/tex] = 1^5 = 1

Answer:

I don't know what he did wrong, but to work out the percentage change, you do 10 ÷ 14, which gives you 0.71.

1 - 0.71 = 0.29

0.29 × 100 = 29%  You multiply by 100 to get your percentage change value.

29% is the percentage change.

Answer: D. y = 3x + 2

Step-by-step explanation: because that's what it shows in the graph

Answer:

D. y = 3x + 2

Step-by-step explanation:

y = mx + b,

where m = slope = rise/run,

and b = y-intercept

From the graph we see that b = 2, s we have

y = mx + 2

Now we look for the slope. Start at (0, 2), the y-intercept, go up 3, a rise of 3, and right 1, a run of 1 to the next point on a grid line intersection.

m = slope = rise/run = 3/1 = 3

Now we have

y = 3x + 2

Answer: D. y = 3x + 2

The value of x is 17

An equation between two variables that gives a straight line when plotted on a graph.

Given,

x represents a certain number

Number is multiplied by 3 = 3x

Adding 34 to the number = x+34

Given,

The number x is multiplied by 3 the result is the same as adding 34 to the number x​

Therefore

3x = x+34

3x-x =34

2x =34

x = 17

Hence, the value of x is 17

Step-by-step explanation:

For the given sides to form a triangle.

The sum of any 2 sides must be greater than the third side.

6.8 + 6.5 = 13.3 > 12.2

9514 1404 393

Answer:

Step-by-step explanation:

The key with naming corresponding parts is to use the congruence (or similarity) statement. Corresponding vertices are those that are in the same position in the congruence statement, regardless of what the figure may look like.*

Angles can be named using the letter at its vertex--if there is only one angle with that vertex--or using three letters. The three letters name a point on one ray, the vertex, and a point on the other ray. When naming corresponding angles from a congruence statement, it is nice (but not absolutely essential) to name the corresponding rays in the same order. In any event, the named vertices must be corresponding.

Sides are named using two letters--the points at the end of the side. The points used to name corresponding sides must come from the same positions in the congruence statement. Technically, side named AB is the same as side BA, but it is nice to use corresponding points in the same order when naming corresponding sides. Example: in the first figure, CB≅JK, but it is also true that BC≅JK because CB can be named either as CB or BC. In both cases, the points named are the 1st and 2nd in the congruence statements.

In the answer section above, we have used 3-letter angles where a vertex is shared by two or more angles. We have used single-letter names for angles where there is no ambiguity. When asked to name all the names, as here, it is best to make use of a pattern you understand. For angles, we worked left-to-right down the congruence statement; for sides we used the pattern 12, 13, 23 for the positions of the letters in the congruence statement.

_____

* Sometimes, poorly-edited curriculum materials will misstate the congruence statement. It is best to report the problem to your teacher in those cases. Sometimes, the figure is intentionally misleading (as in the second problem here). For those, you must pay careful attention to the congruence statement.

Answer:

100 miles

Step-by-step explanation:

Given data

let the number of miles driven be x

and the total charge for x miles be y

Hence the expression for the total charge is

Rapid Rental Car

charges a $55.00 rental fee plus $0.25 per mile driven.

y= 55+0.25x--------------1

Capital Cars charges a $45.00 rental fee and $0.35 per mile driven.

y= 45+0.35x--------------2

Equate 1 and 2

55+0.25x= 45+0.35x

collect like terms

55-45=0.35x-0.25x

10=0.1x

x= 10/0.1

x= 100 miles

Hence the mile is 100 miles
