given the following equation, write a scenario that would lead to writing the equation. 2r + 15 = 25

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

Area of base = 7× 5/2= 17.5 cm²

Perimeter of base = (7+7+7) = 21 cm

Surface area = 2B + Ph

Surface area of prism = 2×17.5+ 21×10 = 245cm²

Volume = Bh = 17.5×10 = 175 cm³

Answer:

(s+16)(s-16)

Step-by-step explanation:

s^2-256

s^2-(16)^2

a^2-b^2= (a+b)(a-b)

(s+16)(s-16)

Answer:

1.      5 ( − 6 ) 2

2.     (−16)(+16)

3.     ( 7q-3r) ^2  

Step-by-step explanation:

5a^2 - 60a + 180   we factor 5 as multiple of a alone (outside of brackets)

Then we keep the common a with its number as 180 doesn't share a

Then we look solely for two numbers that add up to 60 and multiply to 180

We show in the first line what we found and then continue to factor the square of a in format of 5a^(2) and format of -6a-6a to find 5(a2−6a−6a+36) like below until its completed in factored form - 6 -6 would multiply to find +36 and -6-6 subtracts to find -12.

5a^2 - 60a + 180

5(  ^ 2 − 1 2 + 3 6)  

5 ( ^ 2 − 6 − 6 + 3 6 )

5(a^{2}-6a-6a+36)

5(a2−6a−6a+36)

5 ( ( − 6 ) − 6 ( − 6 ) )

5 ( − 6 ) ( − 6 )

5 ( − 6 ) 2

2.

s^2 - 256

2 + 1 6 − 1 6 − 2 5 6

(+16)−16(+16)

(−16)(+16)

3.  

49q^2 + 42qr + 9r^2

(7q )^2 + (7 x 6 + qr) + 3r^2  like by like = 7q and 3r as 3+3 = 6 when squared is our factor outside of brackets and we notice that 6 is not squared in rule.

( 7q-3r) ^2

Answer:

Her trip took 2hrs 30 minutes

Step-by-step explanation:

First part: She was going 80 miles an hour and only travels 40 miles so that's 30 minutes.

Second part: she traveled 100 miles at a speed of 50 miles per hour so that's two hours.

2hrs + 30 mins

2hrs 30 mins

Answer: Hey, the answer is 2 dogs

Step-by-step explanation:

"Mean" means Average and these problems are easy to solve I promise there are ten numbers listed add all of them together 2+1+3+2+2+1+4+0+1+4 That will add up to 20 you divide 20 by ten because there are ten numbers. There are good videos about this on Khan academy for median, mode, and mean which I assume is the unit you're on. :)

Answer:

(-2,3)

Step-by-step explanation:

:)

Answer:

Step-by-step explanation:

angle 2 is 43 degree because angle 2 and 43 are vertically opposite angle and vertically opposite angles are always equal.

angle 1 is 137 degree because the sum of two angles in a straight line is always 180 degree.so

43+angle 1=180 degree

angle 1=180-43 degree

angle 3 is 137 degree because the relation between between angle 3 and 137 degree is vertically opposite angles and vertically opposite angles are always equal.

vertically opposite angles=e and c

complementary angle=b and c

supplementary angle=e and d

Answer: I got this-...

Answer:

perimeter= p1+p2 +p3+p4=add all sides.

area =l×b=

(10m×14m)= 140m

Answer:

Perimeter = 33.4248cm

Area = 29.42478cm²

Step-by-step explanation:

Perimeter = half circle + rectangle length + radius + 90degree section + rectangle length + radius

radius of the circles = (14 - 10)/2 = 2

Perimeter = 2π + 10 + 2 + π + 10 + 2

Perimeter = 3π + 24 = 33.4248cm

Area = half circle + rectangle + quarter circle

Area = π(2)²/2 + 10×2 + π(2)²/4

Area = 29.42478cm²

Answer:

The box which weights a ton.

Step-by-step explanation:

Ounces are smaller than pounds, and pounds are smaller than a ton.

Answer:

The third box weighed the most.

Step-by-step explanation:

Tons weigh a lot more than pounds and ounces.

the given equation is 3x-5=7

so directly talking about results

3x=7+5

3x=12

x=4

now you have the given results now prepare this algebra tiles according to the results

To find the area of this square, we have to figure out what to do with given radius

Radius makes half of the square's diagonal, therefore: d=2r=32d=2r=32 mm. Now we have to find the side aa to find the area.

To find aa, use the Pythagorean Theorem.

[tex] d^{2}&=a^{2}+a^{2} \\ 32^{2}&=2a^{2}\\ 1024&=2a^{2}\\ 512\text{ mm}^{2}&=a^{2}a^{2}[/tex]

Set the equation accordingly.

Substitute for d.

You can keep a2 as we will use it in the area.

Answer:

y=10x

Step-by-step explanation:

The slope is 10/1 and it's positive.

Answer:

x= 29 degrees,  y= 61 degrees

Step-by-step explanation:

Complementary angles and up to 90 degrees, . Sif half of 90 is 45 and y is 16 more than x,  you just need to add 16 to y and subtract 16 from x.
