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:

Answer below :)

Step-by-step explanation:

Hi there!

Question 4 - the answer will be 5. Since the scale factor is 5, we would (hypothetically) multiply the area by 5 to get the new area of XYZ, so area XYZ is 5 times the area of ABC.

Question 5 - A.

First we multiply 45 by 12 to find the amount in inches. This is 540. Now, we divide that by 6 to get 90. This is our scale factor in inches, but the answers only show the scale in feet, so we have to convert. Divide 90 by 12 to get 7.5.

I hope this helps!

Answer:

71.092

Step-by-step explanation:

The number in the standard form i.e. seventy-one and ninety-two thousandths should be considered as the 71.092.

Since the numbers are mentioned in alphabets like

seventy-one and ninety-two thousandths

We have to write in standard form

So, it should be like 71.092.

Hence, The number in the standard form i.e. seventy-one and ninety-two thousandths should be considered as the 71.092.

Answer:

Jacob is [tex]16[/tex] years old.

Step-by-step explanation:

Let the age of Jacob be [tex]x[/tex] years.

Jacob’s sister is [tex]5[/tex] years younger than he is.

So, the age of Jacob's sister be [tex]x-5[/tex] years.

Jacob's twin brothers are [tex]3[/tex] years older than he is.

So, the age of each of the twin brother be [tex]x+3[/tex] years.

Jacob's mom is [tex]3[/tex] times his age.

So, the age of Jacob's mom be [tex]3x[/tex] years.

Jacob's dad is [tex]4[/tex] years older than his mom.

So, the age of Jacob's dad be [tex]3x+4[/tex] years.

Now, the total of all the ages of all his family members is [tex]165[/tex] years.

So, [tex]x+x-5+x+3+x+3+3x+3x+4=165[/tex]

[tex]\Rightarrow 10x+5=165[/tex]

[tex]\Rightarrow 10x=165-5[/tex]

[tex]\Rightarrow 10x=160[/tex]

[tex]\Rightarrow x=\frac{160}{10}[/tex]

[tex]\Rightarrow x=16[/tex]

Hence, Jacob is [tex]16[/tex] years old.

Answer:

An equation of a line with slope -3/2 and x-intercept (4,0) will be:

[tex]y\:=\:-\frac{3}{2}x\:+\:6[/tex]

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

Given

now substitute m = -3/2 and the point (4, 0) in the slope-intercept form of line equation

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

[tex]0\:=\:-\frac{3}{2}\left(4\right)\:+\:b\:\:\:\:\:[/tex]

[tex]-6+b=0[/tex]

Add 6 to both sides

[tex]-6+b+6=0+6[/tex]

Simplify

[tex]b=6[/tex]

Thus, the y-intercept b = 6

now substitute m = -3/2 and b = 6  in the slope-intercept form of line equation

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

[tex]y\:=\:-\frac{3}{2}x\:+\:6[/tex]

Therefore, an equation of a line with slope -3/2 and x-intercept (4,0) will be:

[tex]y\:=\:-\frac{3}{2}x\:+\:6[/tex]

Answer:

Slope-intercept Form: [tex]y = -3x + 16[/tex]

Step-by-step explanation:

Point-slope: [tex]y- y_1 = m (x - x_1)[/tex]

[tex]y + 1 = -3(x - 8)\\y \frac{+8}{-8} = -3x + \frac{+24}{-8} \\y = -3x + 16[/tex]

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:

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

Answer:

360 boxes

Step-by-step explanation:

The number of boxes in the warehouse before 60 boxes were added is;

n = 12k ....  equation 1

where k is the constant of the number of stacks and n is the number of boxes.

The number of boxes after the 60 boxes were added is;

n + 60 = 14k ... equation 2

substitute the value of n in equation 2 for equation 1:

12k + 60 = 14k

60 = 14k - 12k

60 = 2k

k = 60 / 2 = 30

The number of boxes in the warehouse before 60 boxes was added is;

n = 12 * 30 = 360

Answer:

Option D

Step-by-step explanation:

circumference: 2pi x r

r = 9 (6 + 12)/ 2

2 x pi x 9

= 18 pi cm^2 = 56.55 cm^2

Answer:

D. 56.52 cm

Step-by-step explanation:

Circumference = 2*pi*r

Based on the picture, we can see the largest circle has a diameter of 18 cm. (12 + 6)

The radius of the largest circle is half of it's diameter: 18/2 = 9 cm

Now put in the numbers for the circumference equation:

Circumference = 2 * pi * 9 (9 is the radius)

Circumference = 56.5 cm

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
