Answer: The perimeter of the largest triangle = 117 units.

Step-by-step explanation:

Sides of smaller triangle = 10,20 and 15 units

Longest side = 20 units

Longest side of larger triangle = 52 units

Sides of two similar triangles are proportional.

Let k be proportionality constant.

[tex]k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}[/tex]

[tex]k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}[/tex]

Length of other two sides,

[tex]10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}[/tex]

So sides of larger triangle = 52 units, 26 units , 39 units

Perimeter of largest triangle = 52 +26+39 = 117 units

Hence, the perimeter of the largest triangle = 117 units.

Answer:

4 < x < 36;  values that apply are 5, 16, 20, 35

Step-by-step explanation:

use triangle inequality theorem:

the sum of any two sides is greater than the third

16 + x > 20;   x > 4

16 + 20 > x;   x < 36

Answer:

total surface area = 76 sq.cm

Step-by-step explanation:

total surface area of cuboid = 2 ( lb + lh + bh )

( where l is length , b is width and h is height )

so, surface area :

= 2[ (5×4) + (5×2) + (2×4) ]

= 2 [ 20 + 10 + 8 ]

= 2 × 38

= 76 sq.cm

y = 3

Answer:

Over time, mathematicians have developed a set of rules called the order of operations to determine which operation to do first. The rules are: Multiply and divide from left to right. Add and subtract from left to right.

Step-by-step explanation:

Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right.

Answer:

No. The margin of error only includes sampling variability.

Step-by-step explanation:

The margin of error would be considered for the sampling error

In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error

The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors

So there is no margin of error as it only involved the variability in the sampling

Answer:

We conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p      

Step-by-step explanation:

Let 'p' be the original price

Discount = 5% = 0.05

The discount amount can be calculated by multiplying the original price by 5% or 0.05

Discount Amount = 5% × p

                             = 0.05 × p

                             = 0.05 p

Given that the price p of a coat reduced by a 5% discount​.

Thus, the price after 5% discount​ can be calculated by subtracting the discount amount i.e. 0.05 p from the original price p.

Thus,

The expression of the price p after 5% discount​ = p - 0.05 p

                                                                                = 0.95 p

Therefore, we conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p                                                

Answer:

100 boards

Step-by-step explanation:

Step one:

Given data

We are told that Cynthia was paid 20 cents per board for painting the fence

that is for 1 board painted she gets $0.2

If she was paid $10

let us find the number of boards she painted for $10

= 10/0.2

=50 boards

This means that the total boards were 50*2= 100 boards

Answer:

26.7pounds

Step-by-step explanation:

Suppose that an individual has a body fat percentage of 15.9% in weighs 168 pounds

This is calculated as:

Pounds of his weight that is made up of fat is calculated as

Body fat percentage × Body weight in pounds

= 15.9% × 168 pounds

= 15.9/100 = 168 pounds

= 26.712 pounds

Approximately to the nearest tenth = 26.7 pounds

Answer:

$6.72

Step-by-step explanation:

1.68 is 7% of 24, so there is a 7% tax.

96x.07= 6.72

Answer:  The sales tax would be 6.72

Step-by-step explanation: 24 is 1/4 of 96 so that means that you have to multiply the sales tax number by 4 and 1.68 x 4 = 6.72

The simplification of the given expression 9 x 3 is equal to 27.

Multiplication is the mathematical operation that is to determine the product of two or more numbers. If an event can occur in m different ways and if following it, that a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We don not write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together.

We are given the number as 9 x 3

WE can see that the number is multiple of 3

Therefore by using simplification we get;9 x 3 = 27

Hence, the answer is 27.

Answer: 1/4

Step-by-step explanation:

A die has 6 figures which are 1, 2, 3, 4, 5 and 6. There are 3 even numbers which are 2, 4 and 6. A coin has 2 outcomes which are head or tail.

The probability of getting an even number is 3/6 = 1/2.

The probability of getting a head is 1/2.

Therefore, the probability of obtaining an even number and a head will be:

Answer:

2 days

Step-by-step explanation:

According to the problem, calculations of given data are as follows,

Rental charges per day = $68.64

Rental per mile = $0.12

Total miles = 500

Total spend = $210

Let number of days = X

So, we can find number of days by using following equation,

($68.64 × X ) + ( $0.12 × 500) = $210

$68.64 X + $60 = $210

$68.64 X = $210 - $60

$68.64 X = $150

X = $150 ÷ $68.64

X = 2.18 or 2 Days
