Okay so, (3+3) + (6+6) = 6+12)) that is 18m so the perimeter for the rectangle would be 18, the area would be 6x3 and that is 18m2!!

For the square,
Area would be 289ft2 since 17x17 is 289
Perimeter would be 68ft since 17x4 is 68!!
So basically area of a rectangle= L*W
And perimeter of a rectangle = 2 (w + h)
Then area of a square= s2
And perimeter of a square= 4 • s

Answer:

Step-by-step explanation:

The ratios have to be equal so:

1/3 = x/60 Then use cross multiplication

3x = 60

x = 20

Second one

1/3 = x/120

3x = 120

x = 40

Third One

1/3 = x/180

3x = 180

x = 60

Fourth One

1/3 = x/240

3x = 240

x = 80

The perimeter of a triangle is 65 cm. The
lengths of the sides are x cm, x+8 cm, and
X+ 12 cm.
What is the length, in cm, of the longest side of
the triangle?

Answers

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

The longest side measures :

[tex]27\: \: cm[/tex]

[tex] \large \boxed{ \mathfrak{Explanation}}[/tex]

Perimeter of a triangle is equal to sum of measures of its all three sides, that is :

[tex]x + x + 8 + x + 12[/tex]

and according to the question, the perimeter of the triangle is = 65 cm

so, let's equate both the expressions to find value of x :

[tex]x + x + 8 + x + 12 = 65[/tex][tex]3x + 20 = 65[/tex][tex]3x = 65 - 20[/tex][tex]3x = 45[/tex][tex]x = 45 \div 3[/tex][tex]x = 15[/tex]

The longest side of the Triangle is :

[tex]x + 12[/tex][tex]15 + 12[/tex][tex]27 \: \: cm[/tex]

27cm

Step-by-step explanation:

(xcm) + (x+8cm) + ( x+ 12cm) = 65cm

Open Bracket

xcm + x+8cm + x+12cm = 65cm

3x+ 20cm = 65cm

Collect like terms

3x = 65cm - 20cm

3x = 45cm

Divide both sides by 3

3x/3 = 45cm/3

x = 15cm

The longest side of the triangle =( x+12cm)

= (15+12)cm= 27cm

hope this makes sense lol

Step-by-step explanation:

Answer:

1.5 : 1 (or) 3/2

Step-by-step explanation:

Given expression,

→ 3x/2x

Let's simplify the expression,

→ 3x/2x

→ (3 ÷ 2)(x ÷ x)

→ (1.5)(1)

→ 1.5

Now the required ratio will be,

→ 3 : 2

→ 1.5 : 1

Hence, required ratio is 1.5 : 1.

You are buying bottles of a sports drink mix for a softball team. Each bottle costs $1.19. What function rule models the total cost of a purchase? Evaluate the function for 15 bottles

Answers

Answer: f(x) = 1.19x, where f(x) is the total cost, and x is the cost per bottle

Cost of 15 bottles: $17.85

Step-by-step explanation:

This question describes a straightforward relation between cost per bottle, and cost for all the bottles. As such, simply equate one variable to the value of one bottle, and f(x) as the value of every bottle.

Hope it helps :) and let me know if you want me to elaborate.

P.S. f(x) can simply be substituted for "y"

Cost of each bottle=1.19$

Let

no of bottles be x

.The function is given by

[tex]\\ \sf\longmapsto f(x)=1.19x[/tex]

Now

Bottles=15

Cost:-

[tex]\\ \sf\longmapsto f(15)[/tex]

[tex]\\ \sf\longmapsto 1.19(15)[/tex]

[tex]\\ \sf\longmapsto 17.89[/tex]

Round off to the nearest hundredth: 3.6789

Answers

The answer is 3.68, because in order to round to the nearest hundredth, we look to the digit to the right in the thousandths place. If that digit is less than or equal to 4, then all digits to the right are removed; however, if that digit is 5 or greater, then 1 is added to the digit in the hundredths place.

Therefore, in 3.6789, 7 is in the hundredths place and 8 is in the thousandths place. 8 is greater than 5, so we add 1 to 8, and 1+8 = 9.

As a result, 3.68 is the answer.

Answer:

Step-by-step explanation:

To answer, you want to follow PEMDAS:

P = parentheses

E = exponents

M = multiplication

D = division

A = addition

S = subtraction

So, the first step is parentheses, therefore we do whatever is inside the parentheses, and that is multiplying:

(2 * 3) + (3 * 4) =

6 + 12

Now, because there are no exponents, we cannot multiply anymore, and we cannot divide, we can add:

6 + 12 =

And that is our final answer!

To indirectly measure the distance across a river, Nolan stands on one side of the river and uses sight-lines to a landmark on the opposite bank. Nolan draws the diagram below to show the lengths and angles that he measured. Find PRPR, the distance across the river. Round your answer to the nearest foot.

Answers

The length of PR to the nearest foot is 198.94 feet

Find the diagram attached

From the diagram, the triangle PRE and POC are similar triangles.

Let PR = x

Based on similarity theorem;

PR/RE = PR+RO/OC

x/135 = (x+140)/230

Cross multiply

230x = 135(x+ 140)

230x = 135x + 18,900

230x - 135x = 18,900

95x = 18900

x =18900/95

x = 198.94

Hence the length of PR to the nearest foot is 198.94 feet
