D. 1,500 signs

Answers

Answer 1

Answer:

Blaine could make approximately 650 signs in forty hours.

Calculate the working hours

Blaine needs 14 hours to set up his work station. So, out of the total 40 hours, he will have

=> 40 - 14 = 26 hours to actually work on making signs.

Calculate the minimum number of signs he can make

If Blaine makes 16 signs per hour, then in 26 hours, he will make a minimum of

=> 16 * 26 = 416 signs.

Calculate the maximum number of signs he can make

If Blaine makes 23 signs per hour, then in 26 hours, he will make a maximum of

23 * 26 = 598 signs.

Calculate the average number of signs he can make

To get a more reasonable estimate, we take the average of the minimum and maximum number of signs:

Average = (Minimum + Maximum) / 2

= (416 + 598) / 2 = 650 signs.

Hence the correct option is (a).

Jeremy drew a polygon with four right angles and four sides with the same length. What kind of polygon did Jeremy draw?

Answers

A polygon with four sides are called quadrilaterals. Main types of quadrilarerals are:

irregular quadrilateral;
parallelogram -quadrilateral with two pairs of parallel sides;
trapezoid - quadrilateral with at least one pair of parallel sides;
rhombus - quadrilateral whose four sides all have the same length;
rectangle - quadrilateral with four right angles;
square - regular quadrilateral, which means that it has four equal sides and four equal right angles;
kite - quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.

According to this classification, Jeremy drew square that is rectangle with equal sides or rhombus with all right angles.

Answer: square.

Jeremy drew a square or a diamond depending on perception. If all four sides are equal and all 4 angles are exactly right angles then the polygon is even on all sides. This type of shape will result in a square if a looking at a flat surface on top and bottom. If the shape is placed with an angle at the top and bottom it could be perceived as a diamond.

bridget,jim and krutika hare some sweets in the ratio 2:3:3 bridge gets 22 sweets how many more sweets does jim get over bridget

Answers

Jim got 11 more sweets over Bridget.

Step-by-step explanation:

Given,

Bridget, Jim, Krutika got the sweets in the ratio of 2:3:3

Bridget got 22 sweets.

To find how many more sweets does Jim get over Bridget

Let,

Number of sweets they got 2x, 3x, 3x respectively

According to the problem,

2x = 22

or, x = 11

So, Jim got 33 sweets.

Jim got (33-22) = 11 more sweets over Bridget.

Final answer:

By interpreting the ratio 2:3:3 and using Bridget’s share of 22 sweets, it is calculated that Jim gets 11 more sweets than Bridget.

Explanation:

The problem involves sharing sweets between Bridget, Jim, and Krutika in the ratio 2:3:3. Given that Bridget gets 22 sweets which corresponds to the '2' part of the ratio, we need to find what the '3' part (which is what Jim gets) corresponds to. This can be found out by dividing the total sweets Bridget receives by 2 and then multiplying the result by 3.

First, divide 22 (Bridget's sweets) by 2, which equals 11. This represents the '1' portion of the ratio. Multiply this '1' portion (11) by 3 to find out how many sweets Jim gets. 11 multiplied by 3 equals 33. Therefore, Jim gets 33 sweets. Now, how many more sweets Jim gets over Bridget can be calculated by subtracting the number of Bridget's sweets from Jim's sweets. Hence, 33 minus 22 equals 11.

So, Jim gets 11 more sweets over Bridget.
