Answer: D, 1 1/4 cups of flour and 5/4.

Step-by-step explanation:

There are four bowls, so subtract four from 5, and you have 1. Divide the remaining 1 by 4, and you have 1/4. So, 1 1/4 cups per bowl. A simpler way would be to divide 5 by 4, as you would end up with 1.25, which equals 1 1/4.

Answer: 5/4 cups of flower

5 ÷ 4= 1.25

1.25 in fraction form is 5/4, so the answer would be a.

The length of the fence must be 282.84 ft.

Area of the field =  40,000 ft²,

The length of the fence will be equal to the diagonal of the square.

For a square of side length S, the area is:

A = S²

Substituting the values in the formula -

S² = 40,000 ft

Applying the square root on both sides -

S = √(40,000 ft²)

Calculating, the diagonal of a square of side length S is:

D = S x√2,

Substituting the values -

D = √(40,000 ft²) x √2

= √(80,000 ft²)

= 282.84 ft

Answer: The given trinomial, 24ab-16a^2-9b^2, can be written as an expression opposite to a square of a binomial.

To do this, we first factor out the greatest common factor of -4a, which gives us:

-4a(6b-4a-9b^2)

We can then factor -9b^2 as -(3b)^2, and group the remaining terms together:

-4a((3b-2a)^2-4a^2)

So the trinomial can be written as -4a( (3b-2a)^2 - 4a^2 ) which is an expression opposite to a square of a binomial (3b-2a)^2.

Step-by-step explanation:

Answer: To prove that AB is parallel to DC, we can use the following steps:

Draw a diagram of the cyclic quadrilateral ABCD with the point E where sides AD and BC are produced to meet.

Since ABCD is a cyclic quadrilateral, all its interior angles add up to 360 degrees. Therefore, angle A + angle B + angle C + angle D = 360 degrees.

Since AE = BE, we can say that angles A and B are equal (by corresponding angles). Similarly, angles C and D are also equal.

Since angles A and B are equal and angles C and D are also equal, we can say that angle A + angle B = angle C + angle D.

Substituting this into our equation from step 2, we get: angle A + angle B + angle C + angle D = angle A + angle B + angle A + angle B.

Simplifying, we get: 360 = 2(angle A + angle B). This means that angle A + angle B = 180.

Since angle A + angle B = 180, we can say that angle A = angle B and angle C = angle D.

Now we can use the fact that corresponding angles are equal, then angle A = angle C and angle B = angle D.

We know that opposite angles of a parallelogram are equal, so we have proved that AB is parallel to DC.

It's important to note that this proof uses the fact that quadrilateral ABCD is cyclic, which means that the sum of its angles is equal to 360 degrees. It also uses the fact that opposite angles are equal in a parallelogram, and corresponding angles are equal when two lines are parallel.

The selling price of a used book at the store where the owner buys a used book for $1.50 and resells the used book at a price of 400% the price at which buys the used book is $6.00

The selling price of an item is the price which is displayed on the item on the shelves of a store. The selling price is often different from the price at which the item is bought, or produced, which is often lesser than the price at which the item is sold.

The amount at which the owner buys each used book = $1.50

The amount at which the owner of the used book store sells the books = 400% of the amount he paid for the books

400% of an amount x is equivalent to four times the amount. (4 × x)

The price at which the owner sells a used book at his store, P, is therefore;

P = 400% × $1.50 = 400/100 × $1.50 = $6.00

The value of z from the triangle is z = 70

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be represented as ΔIGJ

Let the second triangle be represented as ΔHGK

Now , K is the midpoint of GJ and H is the midpoint of GI

So , IH = GH and GK = KJ

And , the triangles ΔIGJ and ΔHGK are similar

So , corresponding sides of similar triangles are in the same ratio

Substituting the values in the equation , we get

The measure of HK = ( 1/2 ) measure of side IJ

And , ( z - 37 ) = ( 1/2 ) x ( z - 4 )

On simplifying the equation , we get

Multiply by 2 on both sides of the equation , we get

2z - 74 = z - 4
