The amount of more did Ali pay for his cheese is $3.85.

Since Suppose cheese costs $22 per kilogram. Ella buys a 75-gram piece of cheese and Ali buys a 250-gram piece of cheese.

[tex]= (22\times 250) - (22 \times 75)\\\\[/tex]

= $5,500 - $1,650

= $3,850

So it should be like $3.85

hence, The amount of more did Ali pay for his cheese is $3.85.

Answer:

B. The two dimensions are the same in the triangles as they were in the rectangle.

Step-by-step explanation:

Given

Initial Shape: Rectangle (Before cut)

Final Shape: Triangles (After cut)

Note that this can be explained properly with the use of attachments

See attachment 1 for Before Cut

Before Cut represent the full rectangle before Jackie cut the piece of paper.

Let H and B represent the height and base of the triangle

Given that the rectangle is cut diagonally, this means that the cutting starts and ends at the opposite edges of the rectangle

See attachment 2 for After Cut

After Cut represent the two triangles after cutting the rectangle

From the attachment, you'll observe that the dimension of the two triangles (Triangle 1 and Triangle 2) are the same as it is with the rectangle;

In other words, the two triangle have their heights as H and their bases as B.

Hence, it can concluded that the two dimensions are the same in the triangles as they were in the rectangle.

Answer:

c is the correct answer

Step-by-step explanation:

Answer:

$45.15

Step-by-step explanation:

When you are dealing with questions with percents in them—like this one—you have to turn the percent into a decimal. To make 7.5% into a decimal, you move the decimal point 2 spaces to the left. So, 7.5% is also 0.075.

Now, we have to use this formula for these types of questions:

x + x(y)= the price with tax (or markup)

So, we can substitute the variables.

42+42(0.075)=the retail price

42(0.075)=3.15

42+3.15=45.15

So, the retail price will be $45.15

Answer:

The first and second are correct

Step-by-step explanation:

∠X and ∠Y and ∠W and ∠Z are linear angles and supplementary angles, and ∠Y and ∠Z are complementary angles. Then the correct options are A, B, and E.

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.

∠X and ∠Y are linear angles and supplementary angles.

∠W and ∠Z are linear angles and supplementary angles.

∠Y and ∠Z are complementary angles.

Step-by-step explanation:

he starts with 90 bucks to find what the fraction represents you can multiply it by 2 to get an equal denominator of 90 then subtract 90-62 that'll give you 28 then it says he spent 3/7 so you do the same thing get an equal denominator by multiplying by 4 and get 28 and as they say whatever you do to the denominator is done to the numerator so 3 times 4 is 12 then you do 28-12 and you gets 16 which isn't enough to buy the hat. :)

Answer:

The area of  the space on the plate that is not covered by the napkin is[tex]81(\pi-1)\ in^2[/tex]

Step-by-step explanation:

step 1

Find the area of the plate

The area of a circle is given by the formula

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=18/2=9\ in[/tex] ---> the radius is half the diameter

substitute

[tex]A=\pi (9)^{2}\\A=81\pi\ in^2[/tex]

step 2

Find the area of the square napkin folded (is a half of the area of the square napkin)

we know that

The diagonal of the square is the same that the diameter of the plate

Applying Pythagorean theorem

[tex]D^2=2b^2[/tex]

where

b is the length side of the square

we have

[tex]D=18\ in[/tex]

substitute

[tex]18^2=2b^2[/tex]

solve for b^2

[tex]b^2=162\ in^2[/tex] -----> is the area of the square

Divide by 2

[tex]162/2=81\ in^2[/tex]

step 3

Find the area of the space on the plate that is NOT covered by the napkin

we know that

The  area of the space on the plate that is NOT covered by the napkin, is equal to subtract the area of the square napkin folded (is a half of the area of the square napkin) from the area of the plate

so

[tex]A=(81\pi-81)\ in^2[/tex]

simplify

[tex]A=81(\pi-1)\ in^2[/tex]

Final answer:

The volume of the triangular pyramid is calculated by finding the area of the triangular base and then using the volume formula for a pyramid, resulting in a volume of 15 cubic inches.

Explanation:

To find the volume of a triangular pyramid, we use the formula for the volume of a pyramid, which is V = (1/3) × base area × height. First, calculate the area of the triangular base using the formula for the area of a triangle, A = (base length × base height) / 2. In this case, the base length is 3 inches, and the base height is 5 inches.

Therefore, the area of the triangle is A = (3 in. × 5 in.) / 2 = 7.5 in.². Now, we can calculate the volume of the pyramid using the height of the pyramid, which is 6 inches.

The volume of the pyramid is V = (1/3) × 7.5 in.² × 6 in. When you calculate this, you get V = 15 in.³, which is the volume of the pyramid.

Answer:

3(x+5) (x+6)

Step-by-step explanation:

The factored form of 3x² + 33x + 90 is: 3(x + 6)(x + 5)

To factor completely the quadratic expression 3x² + 33x + 90, we can look for two binomial factors that multiply together to give us the original expression.

First, we can check if the expression can be factored by using the common factor 3:

3x²+ 33x + 90

We can factor out 3 from each term:

3(x^2 + 11x + 30)

Now, we need to find two binomial factors that multiply to give us x² + 11x + 30.

The factors can be determined by factoring the quadratic expression further:

x² + 11x + 30 = (x + 6)(x + 5)

Therefore, the completely factored form of 3x² + 33x + 90 is:

3(x + 6)(x + 5)

Answer:

Hey  i got the top one its AXY and XBC ar corresponding angles

Step-by-step explanation:

help it helps you ,i will look and try to do the bottom one aswell, kan you mark me the brainlist pls.

Final answer:

Angle XBC equals 55° because of the Alternate Interior Angles Theorem applied to the parallel lines XY and BD. Angle BXC in triangle XBC is worked out to be 70° due to the Angle Sum Property of a triangle, considering triangle XBC is isosceles with XB equal to XC.

Explanation:

Angle Measurements in Parallel Lines and Triangles

When considering XY and BD as parallel lines, and points X on AB and C on BD such that XB = XC, we can analyze the angles formed using the properties of parallel lines and triangles.

a) Angle XBC = 55° because of the Alternate Interior Angles Theorem, which states that when two parallel lines are crossed by a transversal, the alternate interior angles are congruent. Since XY and BD are parallel, and AB is a transversal, angle XBC is congruent to the alternate interior angle on the opposite side, which must also measure 55°.

b) To work out angle BXC, consider triangle XBC which is isosceles given that XB = XC. Since angle XBC is 55° and triangle XBC has two equal sides (XB and XC), the base angles (XBC and XCB) are equal. So angle XCB is also 55°. The sum of all angles in a triangle is 180°, so angle BXC = 180° - (55° + 55°) which equals 70°.

The reason that angle BXC is 70° is due to the Angle Sum Property of a triangle, which is the sum of angles in a triangle is always 180°.

Answer:To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

Part a

theta = pi/3

sin(pi/3) = sqrt(3)/2

cos(pi/3) = 1/3

tan(angle) = opposite/adjacent = rise/run = slope

tan(pi/3) = sin(pi/3)/cos(pi/3) = (sqrt(3)/2)/(1/2) = sqrt(3)

This is also the slope the line y = kx because it is in the form y = mx+b with m = sqrt(3) and b = 0.

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

Part b

Pick any value you want for x, and plug it in to find the paired value of y

if x = 0, then y = 0 because

y = sqrt(3)*x = sqrt(3)*0 = 0

---------

If x = 1, then y = sqrt(3), since,

y = sqrt(3)*x = sqrt(3)*1 = sqrt(3)

---------

If x = sqrt(3), then,

y = sqrt(3)*x = sqrt(3)*sqrt(3) = sqrt(3*3) = sqrt(9) = 3
