Answer: 3t+4q.

Step-by-step explanation: Triangles have 3 sides, so there will be 3 sides for each triangle in the envelope. This is represented by 3t. Quadrilaterals have 4 sides, so there will be 4 sides for each quadrilateral in the envelope. This is represented by 4q. The total number of sides will be the number of triangle sides and the number of quadrilateral sides together.

Answer:

13t² + 2t + 9

Step-by-step explanation:

(9t² - 3t + 5) - (-4t² + 5t + 4)

Solving like terms

-(-4t²) becomes + 4t²

(9t² + 4t²) + (-3t + 5t) + (5+4) =

13t² + 2t + 9

Answer:

★ Given :

Cost of 50 chickens and 30 ducks = $ 550

Cost of 44 chickens and 36 ducks = $ 532

★ To find :

Cost of chicken and duck

★ Solution :

Assume :

Cost of chicken = x

Cost of duck = y

According to question :

50x + 30y = 550 ......(1)

44x + 36y = 532......(2)

1) - (2)

(50x + 30y) - (44x + 36y) = 550 - 532

50x + 30y - 44x - 36y = 18

6x - 6y = 18

6(x - y) = 18

x - y = 18/6

→ x - y = 3 ....(3)

In equation 1 ,

50 x + 30y = 550

taking 10 common

10(5x + 3y) = 550

5x + 3y = 550/10

5x + 3y = 55

by taking 3 common

3(5/3 x + y) = 55

by dividing 3 on both sides

5/3x + y = 55/3 .....(4)

(3) + (4)

x - y + 5/3 x + y = 3 + 55/3

x + 5/3 x = 64/3

8/3 x = 64/3

by multiplying 3 on both sides

8x = 64

x = 64/8

→ x = 8

→ Cost of chicken = $ 8 ..

by putting value of x in equation 3

x - y = 3

8 - y = 3

y = 8 - 3

→ y = 5

→ Cost of ducks = $5..

Answer:

The true statement is;

B. The total surface area is multiplied by 2.25

The volume is multiplied by 3.375

Step-by-step explanation:

By scale drawing proportionality, we have;

The amount by which all the dimensions of the cylinder are multiplied to create an image of the cylinder = 1.5

∴ The scale factor between the original cylinder and the image of the cylinder, S.F. = 1.5

By rule, we have;

The area factor of the surface area = S.F.² = 1.5² = 2.25

Therefore;

The total surface area of the original cylinder is multiplied by 2.25 to get the total surface area of the image of the cylinder

By rule, we have;

The volume factor = S.F.³ = 1.5³ = 3.375

Therefore;

The volume of the original cylinder is multiplied by 3.375 to find the volume of the image of the cylinder.

Answer:

y+1=-3(x+2)

Step-by-step explanation:

point-slope form is the formula y-y1=m(x-x1), where (x1, y1) is a point and m is the slope

we are given a point (-2, -1) and a slope of -3

all we really need to do is substitute the given into the formula

remember: since the formula gives subtraction, we're going to be subtracting, even though we have negative numbers

substitute -2 as x, -1 as y and -3 as m

y--1=-3(x--2)

we can simplify this equation:

y+1=-3(x+2)

Answer:

length of dotted diagonal line = 11

Step-by-step explanation:

Using the Pythagorean theorem:

length of rectangle² = 9² + 6² = 81 + 36 = 117

length of rectangle = √117 = 10.82

length of diagonal² = 2² + 10.82² = 4 + 117 = 121

length of diagonal = 11

Answer:

The margin of error will be "0.65". A further explanation is provided below.

Step-by-step explanation:

The given values are:

n = 343

x = 110

At 99% confidence level,

[tex]\alpha = 1-99[/tex]%

  [tex]=1-0.99[/tex]

  [tex]=0.01[/tex]

then,

[tex]\frac{\alpha}{2} =\frac{0.01}{2}[/tex]

  [tex]=0.005[/tex]

or,

[tex]Z_{\frac{\alpha}{2} }=Z_{0.005}[/tex]

     [tex]=2.576[/tex]

Now,

The point estimate will be:

⇒  [tex]\hat{P}=\frac{x}{n}[/tex]

⇒      [tex]=\frac{110}{343}[/tex]

⇒      [tex]=0.321[/tex]

or,

⇒  [tex]1-\hat{P}=1-0.321[/tex]

⇒            [tex]=0.679[/tex]

The margin of error will be:

⇒  [tex]E=Z_{\frac{\alpha}{2} }\times \sqrt (\frac{(\hat{P}\times (1 - \hat{P})) }{n} )[/tex]

On substituting the above values, we get

⇒      [tex]=2.576\times \sqrt{\frac{0.321\times 0.679}{343} }[/tex]

⇒      [tex]=2.576\times \sqrt{\frac{0.217959}{343} }[/tex]

⇒      [tex]=0.065[/tex]

hence,

⇒  [tex]\hat{P}-E<p<\hat{P}+E[/tex]

⇒  [tex]0.321-0.065<p<0.321+0.065[/tex]

⇒  [tex]0.256,0.386[/tex]

Answer:

60

Step-by-step explanation:

If  Isabelle sells 150 out of 250 ears of corn. Then the percentage of the ears of corn she sold will be 60%.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Every morning she starts with 250 ears of corn.

On Saturday, Isabelle sells 150 out of 250 ears of corn.

Then the percentage of the ears of corn she sold will be

[tex]\rm P = \dfrac{150}{250} \times 100\\\\P = 15 \times 4\\\\P = 60 \%[/tex]

Answer:

  A.  10 units

Step-by-step explanation:

The y-intercept of f(x) is f(0) = -9.

The y-intercept of g(x) is g(0) = g(1)/2 = 1.

The distance between these points is ...

  1 -(-9) = 10 . . . units

__

We notice that the common ratio of the table values of g(x) is 4/2=2, so the value for x=0 will be a factor of 2 less than the value for x=1.
