Question: Determine whether the dilation from figure K to K’ is an enlargement or a reduction

We know that the surface area of cuboid with sides L, B and H is given by,

S = 2 (LB + BH + LH)

Given that the sides of cuboid are x cm, 5 cm and 7 cm.

So L = x cm and B = 5 cm and H = 7 cm.

Given that the surface area of the cuboid is 142 square cm.

According to information the suitable equation for this is:

2(5x+7*5+7x) = 142

Now solving the equation we get,

5x+35+7x = 142/2 = 71

12x+35 = 71

12x = 71-35

12x = 36

x = 36/12

x = 3

Hence the value of x is 3 cm.

Answer:

y=1/2x+2

Step-by-step explanation:

slope form is y=mx+b

m-slope

b- y intercept (when x is 0)

To find slope we use y2-y1/x2-x1

4-3/4-2

1/2 is the slope

Now we know every time X goes up 1 y goes up 1/2 so we subtract back to find y intercept

(1,2.5)

(0,2)

Y intercept is 2

The size of the outer ring of the pizza = 25.12 inches

The amount of cheese covering the entire top of the pizza =  50.24 sq inches.

A small pizza has a diameter of 8 inches.

A Pizza has a circular base structure whose diameter, d = 8 inches.

Radius of the pizza, r = d/2 = 8/2 = 4 inches.

The size of the outer ring of the pizza means we talk about the circumference of the pizza.

The size of the outer ring of the pizza = 2πr

If we take the value π = 3.14 ( round off figure)

Then  the size of the outer ring of the pizza = 2×3.14×4=25.12 inches.

The amount of cheese covering the entire top of the pizza means we talk about entire top area of the pizza.

The amount of cheese covering the entire top of the pizza = π × r^2

= 3.14 ×4×4

The amount of cheese covering the entire top of the pizza =  50.24 sq inches.

The roots of the quadratic equation 0 = 2x² + 12x-14 is (C) x=-7 and x=1.

Any equation in algebra that can be written in the standard form where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation.

In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler.

So, the roots of 0 = 2x² + 12x-14 are:

2x² + 12x-14  = 0

2x² + 14x - 2x -14

2x(x + 7) - 2(x + 7)

(2x - 2) (x + 7)

Now, use the zero product property as follows:

2x - 2 = 0

2x = 2

x = 2/2

x = 1

And

x + 7 = 0

x = -7

Therefore, the roots of the quadratic equation 0 = 2x² + 12x-14 is (C) x = -7 and x = 1.

The ordered pair that shows the dilation of the square ABCD, located at A(-10, -2), B(-5, -2), C(-5, -7), and D(-10, -7), by a scale factor of 5 about the origin is option B

B. A'(-50, -10), B'(-25, -10), C'(-25, -35), and D'(-50, -35)

A dilation transformation is in which the sizes of the sides of the pre image or original figure is changes proportionately to get the image.

The vertex of the preimage ABCD are; A(-10, -2), B(-5, -2), C(-5, -7), and D(-10, -7)

A dilation by a scale factor of 5 is found using the formula;

(x, y) Dilation by scale factor of 5 about the origin ⇒ (5·x, 5·y)

Therefore, the coordinates of the square ABCD following a dilation by a scale factor of 5 is therefore;

A'(5 × -10, 5 × -2), B'(5 × -5, 5 × -2), C'(5 × -5, 5 × -7), and D'(5 × -10, 5 × -7)

Which gives;

A'(-50, -10), B'(-25, -10), C'(-25, -35), and D'(-50, -35)

Checking the lengths of the sides gives;

AB = 5

A'B' = -25 - (-50) = 25

BC = 5

B'C' = -10 - (-30) = 25

CD = 5

C'D' = -25 - (-50) = 25

AD = 5

A'D' = -10 - (-35) = 25

Therefore, the lengths of the sides of A'B'C'D' are 5 times the lengths of the sides of the square ABCD

The correct option is therefore option B

Answer:

1.5 cm

Step-by-step explanation:

Triangles WTY and UTV are similar. Segment WT corresponds to UT and segment YT corresponds to VT. Thus we can create an equation knowing that the ratio of WT to UT must equal to the ratio of YT to VT.

WT = 7.5 cm

UT = ?

YT = 15 cm

VT = 12 cm

WT / UT = YT / VT

7.5 / UT = 15 / 12

UT = 6

WT = WU + UT

7.5 = WU + 6

WU = 1.5

A profit is a financial gain from the revenue that exceeds the sum of expenses and the taxes.

The ingredients required to make 12 cups of punch are;

1 gallon of raspberry and 2 liters of Sprite

Amount he pays for 2-liter of Sprite = $3.00

Amount paid for a quart of sorbet = $4.00

The minimum amount to be charged so as to make a $10 profit is found as follows;

4 quarts is equivalent to one gallon

Therefore;

1 quart of sorbet costs $4

4 quart of sorbet = 1 gallon of sorbet costs 4 × $4 = $16

The cost of 2-liters of Sprite = $3.00

The cost of 12 cups of punch is therefore;

$3 + $16 = $19

Answer:

Step-by-step explanation:

Answer:

the correct one is Slope = -1/6

The probability that only one of the counters is white is the fraction 6/11 or 0.55 considering that the first take is without replacement

The probability for an event without replacement implies that once an item is taken, then we do not replace it back to the sample space before taking a second item.

Given that there are 11 counters in the bag, with 5 of them being white;

The probability of taking a white counter = 5/11

The probability of not taking a white counter = 6/11

The probability of taking a white counter first without replacement and not taking it the second time = (6/11) × (5/10)

The probability of not taking a white counter first without replacement and taking it the second time = (5/11) × (6/10)

The probability that only one of the counters is white = (6/11) × (5/10) + (5/11) × (6/10)

The probability that only one of the counters is white = (30/110) + (30/110)

The fraction of the total number of boats is the number of destroyers is 15/25 and the number of battleships is 0.56 times the number of destroyers.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that, the ratio of battleships to destroyers in the navy is 10:15.

battleships : destroyers = 10:15

The fraction of the total number of boats is the number of destroyers is,

=15/10+15
