Answer:

90 cm^2

Step-by-step explanation:

Divide the rectangle and square into two separate figures and add them together at the end.

Top rectangle: We know that area of a rectangle is A=lw. Here, we see that w=5 cm. For the length, we add 4+5+4=13 (5 comes from the bottom square). So A=5(13)=65

Bottom square: Area of a square is A=s^2 where s=5 in this case, so A=5^2=25

Total Area: Add together two figure's area: A=65+25=90 cm^2

Step-by-step explanation:

Answer:

y = x - 6

Step-by-step explanation:

the slope-intercept form for any line is y = mx + b, where m is the slope and b is the y-intercept.

now, let's calculate the slope:

1-2/7-8= -1/-1 = 1

here is the equation we currently have solved: y = x + b

now we have to solve for the y-intercept. to do this, we substitute one of the given points into the equation, and solve for b.

let's use (8, 2). in this ordered pair, the 8 is the x, and the 2 is the y.

2= 8 +b

2 -8=b

b=-6

and now we have our final equation!

y = x - 6

Answer: C. 4.6 seconds

Answer:

A ≈ 2 ft²

Step-by-step explanation:

The area (A) of a triangle using Heron's formula is

A = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

where s is the semiperimeter and a, b , c the sides of the triangle.

s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{4+4+1}{2}[/tex] = [tex]\frac{9}{2}[/tex] = 4.5

Then

A = [tex]\sqrt{4.5(4.5-4)(4.5-4)(4.5-1)}[/tex]

   = [tex]\sqrt{4.5(0.5)(0.5)(3.5)}[/tex]

   = [tex]\sqrt{3.9375}[/tex]

   ≈ 1.9843...

   = 2 ft² ( to the nearest square foot )

Answer:

30<= .10x +.25y

Step-by-step explanation:

She says she has at least 30, so the total might be equal to or higher than 30. In other words, 30 is equal to or lower than the expression.

The given equivalent function is g(x)=(x+9)(x-2). Therefore, option B is the correct answer.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is g(x)=x²+7x-18

Now, g(x)=x²+9x-2x-18

g(x)=x(x+9)-2(x+9)

g(x)=(x+9)(x-2)

Therefore, option B is the correct answer.

Answer:

ANGLE CBE=25°

EXPLANATION:

LET ANGLE CBE BE X.

ANGLE CBE = ANGLE ABD

CBE=ABD=X

X+X+155°+155°=360°

2X+310°=360°

X=360-310/2

X=50/2

X=25°

Answer:127.45

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 51 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that $100\%=51$.

Step 4: In the same vein, $x\%=65$.

Step 5: This gives us a pair of simple equations:

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

Step 7: Taking the inverse (or reciprocal) of both sides yields

Therfore: 51% of 65 is 127.45

Step-by-step explanation:

Add 75 to 12.55. the answer would be 87.55.

Answer:

its either 1/6 or 3/8

Step-by-step explanation:

3/8 if you are dividing

1/6 if you are multiplying

Step-by-step explanation:

(a)

ii.

21 - 5 = 16 play only chess.

iii.

23 - 5 = 18 play only cards

5 play both.

that is 16+18+5 = 39 that play at least one of these games.

i.

so, 45 - 39 = 6 don't play any of these games.

(b)

we have 16+18 = 34 pupils out of 45 that play exactly one game.

so the probabilty to pick one of them is as usual

desired cases / total cases = 34/45 =

= 0.755555555... ≈ 0.76
