2y^2 + 30xy - 2y^2 + 4y - 4x

Answers

Answer 1
you're gonna have 2y^2 - 2y^2 which cancel out giving you 0 so they dont go into the simplified answer. then, since 30xy is the only one that doesnt have a match you place that down. then place +4y , and then -4x . It will give you 30xy +4y -4x .

or vise versa with the 4y and 4x . whichever your answer choices are or how u prefer to write it. <3

A business named Beyond Boxes is considering adding a box in the shape of a triangular prism as shown. How much cardboard will be needed to make this design?
A.96 cm2

B.102 cm2

C.108 cm2

D.76 cm2

Answers

Answer:

120

Step-by-step explanation:

108 cm² cardboard will be needed to make this design.

As per the given data:

The shape of the box is a triangular prism, and all the dimensions are given in the diagram.

A polyhedron with two triangular bases and three rectangular sides is referred to as a triangular prism. It is a three-dimensional form with two base faces, three side faces, and connections between them at the edges.

To find the cardboard that will be needed to make this design:

= Total surface area of the triangular prism.

= Area of 2 triangles + area of 3 rectangles

= 2 × ½ × 3 × 4 + 4 × 8 + 5 × 8 + 8 × 3

= 12 + 32 + 40 + 24

= 108 cm²

Hence, 108 cm² cardboard will be needed to make this design.

If mImage of an angle symbol4 = 75°, then what is mImage of an angle symbol8?
A. 105°
B. 75°
C. 175°
D. 25°

Answers

Answer:

105

Step-by-step explanation:

180-75=105

Answer:

75*

Step-by-step explanation:

Angles 4 & 8 are the same because the two parallel horizontal lines have one line going through them and angels 4 & 8 are in the same corner on the two lines. Also, angle 4 has a measure of 75* and if angles 4 & 8 are the same, they will also have the same measure.

Kara works at a fine jewelry store and earns commission on her total sales for the week. Her weekly paycheck was in the amount of $7000, including her salary of $1000. Her sales for the week totaled $50,000. Express her rate of commission as a percent, rounded to the nearest whole number.

Answers

Her total paycheck minus her salary = the commission amount
So
6500 - 1000 = 5500
So....her commission as a percentage of sales = 5500/ 45000 = about 12.2%

A.

B.

76 cm2


C.

96 cm2


D.

108 cm2

Answers

The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps
