ABC DEF. The Area Of DEF Is Given. Find The Area Of ABC.

Answers

Answer 1

Answer:

C. 240 in^2

Step-by-step explanation:

is it stated that two triangles are similar.

If they are similar then their area must be proportional too.

The side lengths' proportion is :

12/60 = 1/5 this can be used to find the area of the smaller triangle, ABC
Let x represent the are of triangle ABC

1/5 = x/1200 cross multiply both sides

5x = 1200 divide both sides by 5

x = 240 since the area is indicated with square value so the answer is

C. 240 in^2

A chef measured the weight in pounds of 12 bags of fruits that she purchased from a
vendor.
The weights in pounds are shown.
Find the median weight.

Answers

Answer:

12

Step-by-step explanation:

Put numbers in order from least to greatest.

8,8,9,9,10,11,13,14,14,14,15,16.

Find the number in the middle.

Because 12 is an even number we have to take the two middle numbers, in this case 11 and 13, add them and then divide that number by 2.

11+13= 24

24 ÷ 2 =12

So the median weight is 12.

Step-by-step explanation:

(1/2) √80

Figure out the biggest number that can be squared by 80 in this case it's 16

(1/2) √(16 x 5)

since the square root of 16 is 4 put the 4 on the outside and leave 5 in since it can't be squared.

solve using the zero product property:

10x^2 - 13x = 3


with explanation pls; will give brainliest

answer should be: -1/5 and 3

Answers


10x^2 - 13x = 3 a = 10, b = -13, c = -3 (quadratic formula? icba to write it sos!!)
-3 both sides

10x^2 - 13x - 3 = 0 -3 x 10 = -30 (products of -30 and equal to -13 are 15, -2 (so we use this))

10x^2 - 2x + 15x - 3 = 0
factorising now

2x (5x - 1) + 3 (5x - 1)
the brackets have to be the same

(2x + 3) (5x - 1)
2x - 3 = 0 ——— 5x + 1 = 0 (switch the signs forgot y tbf)
add 3 to both sides ——— minus 1 on sides
2x = 3 ——— 5x = -1
divide by 2 both sides ——— divide both by 5
x = 3/2 ——— x = -1/5

A cuboid with a breadth of 4 cm and length of 6 cm has a volume of 350 cm3. Find the height of the cuboid, giving you answer to one decimal place.

Answers

Answer:

14.58 m3

Step-by-step explanation:

here, breadth (b) = 4cm

length (l) = 6cm

volume (v) = 350cm3

height (h) = ??

we know, volume of cuboid=

length × breath× height

or, v = L× B × H

or, 350 = 6 × 4 × H

or, 350 = 24 × H

or, 350/25 = H

or 14.58 = H

therefore, H = 14.58cm3

Answer: Option (a) x > 1/6 is the solution to the given expression -2(8x - 4) < 2x + 5.

The solution to the inequality is x > 1/6

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

-2(8x - 4) < 2x + 5

On simplifying , we get

-16x + 8 < 2x + 5

Subtracting 2x on both sides , we get

-18x + 8 < 5

Subtracting 8 on both sides , we get

-18x < -3

Multiply by -1 on both sides , we get

18x > 3

Divide by 18 on both sides , we get

x > 1/6

Hence , the solution is x > 1/6

I bought x cans of fruit cocktail and two more cans of mushrooms than cans of fruit cocktail. A can of mushrooms cost $.80 and a can of fruit cocktail cost $.90. How much money did I spend?

Answers

Answer:

0.9x + 0.8(x + 2)

Step-by-step explanation:

# of cans of fruit cocktail: x

# of cans of mushrooms: 2 more than x, or x + 2

$ of can of mushroom: $0.80

$ of can of fruit cocktail: $0.90

To find out how much money you spent, you need to multiply the # of cans by their respective prices. Therefore:

The price of the cans of fruit cocktail = 0.90 * x

                                                             = 0.9x

The price of the cans of mushrooms = 0.80 * (x + 2)

                                                             = 0.8(x + 2)

Total price = 0.9x + 0.8(x + 2)

Answer:   233.5 square miles

========================================================

Explanatoin:

There are a number of ways to do this type of problem. One way is to divide the figure as shown in the diagram below. See the attached image.

I'm splitting the irregular shape into two rectangles and a triangle.

The upper rectangle is 10 miles by 9 miles to get an area of 10*9 = 90 square miles. Let A = 90 so we can use it later.

The lower rectangle is 4 miles by 19 miles. Its area is 4*19 = 76 square miles. Let B = 76.

The total vertical height of the figure is 9+4+10 = 23 miles.

Notice along the column that has "8 miles" up top over "9 miles" down below, we have a gap of some distance which I'll call x. This x adds to 8 and 9 to get the 23 mentioned.

x+8+9 = 23

x+17 = 23

x = 23-17

x = 6

This helps find the height of the triangle which is 9+x = 9+6 = 15 miles.

The triangle has a base of 9 miles.

The area of the triangle is base*height/2 = 9*15/2 = 135/2 = 67.5 square miles. Let C = 67.5

--------------

We found that:

A = 90 = area of the upper rectangleB = 76 = area of the lower rectangleC = 67.5 = area of the triangle

The total area is: A+B+C = 90+76+67.5 = 233.5 square miles.

Answers

Answer:

[tex]g(x)=x^3-8x^2+9x+11[/tex]

Step-by-step explanation:

[tex]f(x)=-x^3-8x^2-9x+11[/tex]

When a function is reflected across the y-axis, negative x-values become positive, and positive x-values become negative.

Therefore, substitute -x in place of x in the function f(x):

[tex]g(x)=-(-x)^3-8(-x)^2-9(-x)+11[/tex]

We know that [tex](-x)^3=-(x^3)[/tex]

[tex]\implies -(-x)^3=--(x^3)=x^3[/tex]

We know that [tex](-x)^2=x^2[/tex]

[tex]\implies -8(-x)^2=-8(x)^2=-8x^2[/tex]

Also [tex]-9(-x)=+ \ 9x[/tex]

Therefore,

Answer:

C

Step-by-step explanation:

Cross out B and D, because angle D does not correspond with Y and Angle F does not correspond with X (order matters).

It comes down to either A or C, so look at the sides.

DF does not correspond to XY, again, the order it is displayed matters.

D is the first letter and F is the last, while X is the 2nd letter of the triangle, while it should be the first letter to correspond with D

Thus by Process of Elimination the answer is C.
