Step-by-step explanation:

Answer:

1= Perimeter =9.6

Area = 5.76m^2

Answer:

find the perimeter and area:

1. square with a side 2.4 m in length find the perimeter and area

answer:

length [l]=2.4m

area of square=l²=2.4²=5.76m²

perimeter of square=4l=4×2.4=9.6m

2. rectangle with length (x+3) and width 7

answer:

length [l]=x+3

Breadth [b]=7

perimeter of rectangle =2{l+b}=2(x+3+7)=2x+20

area of rectangle=l×b=(x+3)×7=7x+21

Answer:

n = 6 3/7 or 45/7

Step-by-step explanation:

cross-multiply

7n = 45

n = 45/7 or 6 3/7

Answer:

Step-by-step explanation:

9 x 5 = n x 7

45 =n x 7

Switch sides n x 7=45

Divide both sides by 7: n x 7/7 = 45/7

n = 45/7

Answer:

D, roughly 9.4 units

Step-by-step explanation:

you can make the graph into a right triangle

with sides of [tex]x, 5,[/tex] and [tex]8[/tex]

[tex]A^{2} +B^{2} =C^{2}[/tex]

[tex]5^{2} +8^{2} =x^{2}[/tex]

[tex]25+64=x^{2}[/tex]

[tex]89=x^{2}[/tex]

[tex]\sqrt{89} = 9.43[/tex]

Answer:

Because linear pairs of angles are  supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.

Because angles that are  supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.

Step-by-step explanation:

The correct question is attached.

Linear pairs angles are angles which are formed from the intersection of two lines and they are adjacent to each other. Linear pair angles are supplementary.

If angles are supplementary to the same angle, then they are congruent.

∠1 and ∠3 are vertical angles

∠1 and ∠2 form linear pairs while ∠2 and ∠3 form linear pairs. Therefore:

m∠1 + m∠2 = 180° (linear pair angles are supplementary)

m∠2 + m∠3 = 180° (linear pair angles are supplementary)

Hence using transitive property of equality:

m∠1 + m∠2 = m∠2 + m∠3

Using subtraction property of equality by subtracting m∠2 from both sides gives:

m∠1 = m∠3

∠1 ≅ ∠3 (vertical angles are congruent)

Because linear pairs of angles are  supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.

Because angles that are  supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.

Answer:

For number 13 you should get 14 is the width just divide what you got from multiplying the length and the other side. 2 and 95 could be possible answers of number 14.

Answer:

13. Width is 14 inches.

14. 5 and 38

Step-by-step explanation:

Volume (rectangular prism) = length*width*height

1428=17*w*6

w=1428/102

w=14 inches

Base area=length*width

∴Volume (rectangular prism) = Base area*height

190=Base area*height

Pick two numbers that multiply to give 190: 5 and 38.

Answer:

1) [tex]\frac{1}{2^7}[/tex] ; 2) [tex]11^7[/tex]

Step-by-step explanation:

1) Using the Power of a Fraction Rule [tex](\frac{a}{b} )^x = (\frac{a^x}{b^x} )[/tex],

[tex](\frac{1}{2} )^7 = (\frac{1^7}{2^7} )[/tex], which can just be simplified to [tex]\frac{1}{2^7}[/tex].

2) Using the Negative Exponent Rule, [tex]a^{-x} = \frac{1}{a^{x}}[/tex],

[tex](\frac{1}{11} )^{-7} = \frac{1}{\frac{1}{11^7}}[/tex], which can be simplified to [tex]11^7[/tex].

Answer:

Rs. 6300

Step-by-step explanation:

Given that:

Land area = 63m²

Rate of paving brick = RS. 100 per m²

Hence, to pave bring on a 63m² land area ;

Total cost of paving brick will be :

Cost per m² * land area

Rs. 100 * 63

= Rs. 6300

Answer:

The shape is a Dodecagon

Each aquarium has 170 liters of water in it.

Step-by-step explanation:

To get this, you need to divided 850 by 5 to get the amount of water in each tank to make sure that it is all equally distributed. This way we now know that each tank needs 170 liters of water to have an equal amount of water in each tank

Answer:

AB is similar to YZ.

AC is similar to YX.

CB is similar to XZ.

Step-by-step explanation:

Answer:

Slope: 4

Y-intercept: 6

Step-by-step explanation:

The equation is given to you in slope intercept form which is y=mx+b.

In this form m is the slope and b is the Y-intercept. Therefore all you have to do is take the value for m from the equation and put that down for the slope and the value for b as the y-intercept.

Answer:

㏒(2x²) = ㏒(2) + 2㏒(x)

Step-by-step explanation:

As given,  ㏒(2x²)

As we know that ㏒(MN) = ㏒(M) + ㏒(N)

⇒㏒(2x²) = ㏒(2) + ㏒(x²)

As we know that ㏒(xⁿ) = n㏒(x)

⇒㏒(2x²) = ㏒(2) + 2㏒(x)

∴ we get

㏒(2x²) = ㏒(2) + 2㏒(x)

Answer:

304 m²

Step-by-step explanation:

l = 10 m

b = 7 m

h = 4 m

TSA = 2 (lb + bh + hl)

       = 2 (10 * 7 + 7 * 4 + 4 * 10)

       = 2 (70 + 42 + 40)

       = 2 * 152

       = 304 m²

Hope it helps :)

Answer:

y - intercept: 3/4

slope: -5/4

Step-by-step explanation:

put into slope-intercept form first, y = -5/4x + 3/4

then you can see that the slope and y - intercept are -5/4 and 3/4

Answer:

The answer for the y-intercept is (0, -3/4). The answer for the slope is -5/4.

Step-by-step explanation:

You know this because you must pull the 4 out of the equation, along with the y, so it is -4y=5x+3. You would put both of these numbers over 4: (5 and 3). A positive number which is 5, divided by a negative gives you negative so you can just say -5/4. Same with +3/-4. You can change it to -3/4, because positive over negative equals negative answer.
