Here is a diagram that represents (3.1) ⋅ (1.4).
What is the area of rectangle A?
What is the area of rectangle B?
What is the area of the outer rectangle which measures 3.1 units by 1.4 units?

Answers

Answer 1

Step-by-step explanation:

1. solution,

length of rectangle A(l)=3.1units

breadth of rectangle A(b)=1units

now,

area of rectangle A=l×b

=3.1units×1units

=3.1 sq units

2.solution,

length of rectangle B(l)=3.1units

breadth of rectangle B (b)=0.4units

now,

area of rectangleB=l×b

=3.1units×0.4units

=1.24 sq units

3.solution,

length=3.1units

breadth=1.4units

area =lxb

=3.1units x 1.4units

=4.34units

Answer 2

Answer:

1) 3.1 2) 1.24 C) 4.34

Step-by-step explanation:

Area = l(w)

Area of rectangle A:

3.1 * 1 = 3.1

Area of rectangle B:

0.4 * 3.1 = 1.24

Both rectangles put together:

First, let's add 1 to 0.4... 1.4

1.4 * 3.1 = 4.34

I really, really, really hope I helped you. Good Luck :D

Latasha deposits 250$ into a account savings. The simple intrest rate paid is 3.5%. how much interest does Latasha earn in one year?

Answers

Multiply $250 by 3.5% = 8.75
250 + 8.75 = 258.75

The amount of interest that Latasha earns in one year will be $8.75.

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

The formula for interest is written as,

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

Latasha deposits $250 into her account savings. The simple interest rate paid is 3.5%.

Then the amount of interest that Latasha earns in one year will be given as,

I = ($250 x 3.5 x 1) / 100

I = $875 / 100

I = $8.75

The amount of interest that Latasha earns in one year will be $8.75.

Select all the statements that would be true in a probability model for rolling a cube with faces numbered 1 through 6.

Sample space: 1, 2, 3, 4, 5, 6

P(1) = 16

P(2) = 26

P(6) = 16

The outcomes of the trial: 2, 2, 2, 5, 3, 2, 6, 5, 6, 1

Answers

Answer: A,B, D and E.

Step-by-step explanation:

When a cube with faces numbered 1 through 6 is rolled:

(A)The sample space is 1,2,3,4,5,6. Option A is correct

(B) P(rolling a 1) =1/6, Option B is correct

(C)P(rolling a 2)=1/6, therefore option C is incorrect.

(D)P(rolling a 6)=1/6, Option D is correct

(E)In an experimental trial, the outcome must be members of the sample space. Therefore, the outcomes in option (E), 2, 2, 2, 5, 3, 2, 6, 5, 6, 1 are valid.

Answers

Answer:

The correct sequence of transformations that shows that △ABC is similar to △A′B′C′ is:

translation of 2 units left followed by a dilation with respect to the origin by a scale factor of 12.

Step-by-step explanation:

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object.

In this case, we can see that a dilation with respect to the origin by a scale factor of 12 would stretch or shrink the triangle, but would not change the angles.

Therefore, we need to apply a translation first to move the triangle into the correct position.

So, we first translate the triangle 2 units left, which does not change its shape or size, but moves it to a position where it can be more easily compared to the other triangle.

Then, we apply a dilation with respect to the origin by a scale factor of 12, which stretches or shrinks the triangle but does not change its shape.

Classify this triangle.

A. Acute scalene triangle
B.Obtuse isosceles triangle
C. Right isosceles triangle
D Right scalene triangle

Answers

It is a right isosceles triangle, C

A triangle with two sides of equal length and the angle where these two sides meet is 90° is Right isosceles triangle. Therefore, option C is the correct answer.

What is a right triangle?

A right angled triangle is a triangle with one of the angles as 90 degrees. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.

A right triangle with two equal-length legs is called an isosceles right triangle. The corresponding angles would also be congruent because the lengths of the two legs of the right triangle are equal. As a result, the two acute angles and two legs of an isosceles right triangle are congruent.

Therefore, option C is the correct answer.

56.52 you’re going to take the radius times 2 to get diameter and then diameter times pi or 3.14

The formula for area of a circle is A=πr^2
Radius is the distance halfway across the circle so in this case, r=9
Now just plug the radius value into the equation:
A = π(9)^2 —> A = π(81) —> A = 254.34 —> round to the nearest tenth A = 254.3
