Solve 58x29 using an area model

Answers

ugh I know the answer but like it wont let me take a pic of how to do it and the answer ugh sorry I will answer it as soon as I can

Final answer:

To solve 58 x 29 using an area model, we break down the numbers into tens and ones, use these as dimensions in the area model, and add up the areas to find the product. The product of 58 x 29 is 1682.

Explanation:

To solve 58 x 29 using an area model, we will break down the numbers into tens and ones. Both 58 and 29 can be written in a different form: 58 = 50 + 8 and 29 = 20 + 9.

Next, we divide the area model (or grid) into 4 parts having the dimensions 50 x 20, 50 x 9, 8 x 20, and 8 x 9. Multiply these dimensions together to get 1000, 450, 160, and 72 respectively.

The last step is to add all those areas together, which gives 1000 + 450 + 160 + 72 = 1682. So, the product of 58 x 29 is 1682 using the area model method.

What is the area of the figure?

cm2

Answers

Area of the figure is 135cm²

Given:
length of the base : 15 cm
height of the figure : 13 cm
height of the triangle : 8 cm

Area of the rectangle = Length x width

Width = height of the figure - height of the triangle
= 13 cm - 8 cm
Width = 5 cm

Area of the rectangle = 15 cm x 5 cm = 75 cm²

Area of the triangle = height x base x 1/2
= 8 cm x 15 cm x 1/2
= 120 cm² / 2
Area of the triangle = 60 cm²

Area of the figure = Area of Rectangle + Area of Triangle
= 75 cm² + 60 cm²
Area of the figure = 135 cm²

Delaney would like to make a 5lb mixture that is 60% peanuts and 40% almonds. She has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds. Let p represent the number of pounds of peanuts needed to make the new mixture,and let m represent the number of pounds of the 80% almond-20% peanut mixture.(a) What is the system that models this situation?
(b) How many pounds of peanuts and how many pounds of the 80% almond-20% peanut mixture will she need?

Answers

This is a mixture problem. Let's call the mixture of

20%peanuts - 80% almonds as mixture A

Let's call the

100% peanuts as mixture B

and the

60% peanuts - 40% almonds as mixture C

Since we get mixture C by adding mixture A and B together, we know that the amount in pounds of mixture A and mixture B is 5 pounds.

Hence we

let m be the amount in pounds of 20%peanuts-80% almonds mixture, or mixture A

and

50-m be the amount in pounds of mixture B

So, the system of equations that models this situation is:

0.20m + 1(50-m) = 0.60(5)
0.80m + 0(50-m) = 0.40(5)

Solving for m using equation 2 gives us

m = 2.5 lb.

That means it will take 2.5 lb of mixture A (20%peanuts-80%almonds) and 2.5 lb of mixture B (100%peanuts) to form 5 lb of mixture C (60%peanuts-40%almonds).

Answers

The fraction $(3)/(9)$ can be written as $(1)/(3)$ in the simplest fraction form.

A fraction is a mathematical expression that represents a portion or a division of an entire. It's utilized to portray numbers that aren't whole numbers or integers. A fraction consists of two factors

1. Numerator: The numerator is the number on the top of the fraction. It represents the quantity or portion of the whole being reckoned.

2. Denominator: The denominator is the number at the bottom of the fraction. It represents the complete number of equal parts into which the whole is divided.
