Here Is A Diagram That Represents (3.1) (1.4).What Is The Area Of Rectangle A?What Is The Area Of Rectangle

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

-10 ≤ 2(2x + 7) ≤ 10.

Answers

Answer:

Step-by-step explanation: So first I changed 2(2x + 7) with the distributive property:

4x + 14

Since the above has to be less than or equal to 10, I know that x has to be negative.

If we make x = -1, 4x + 14 simplifies to -4 + 14, which simplifies to 10.

This satisfies the inequality, since it is greater than or equal to -10, and less than or equal to -10.

Hope this explained it well!

Answer:

-6 ≤ x ≤ -1.

Step-by-step explanation:

-10 ≤ 2(2x + 7) ≤ 10

Split it up into 2 inequalities:

2(2x + 7) ≥ -10    (reading from the middle to the left)

4x + 14  ≥ -10

4x  ≥ -24

x  ≥ -6.

and:

2(2x + 7) ≤ 10

4x + 14 ≤ 10

4x ≤ -4

x ≤ -1.

Combining the 2 we have:

-6 ≤ x ≤ -1.

Hazel is putting together charm bracelets. For each bracelet 1/5 of a yard of string and 12 charms. hazel has 5/8 of a yard of string and 96 charms. she makes the charm bracelet until all of the string is gone. what fraction of charms did she use?

Answers

Answer:

3/8

Step-by-step explanation:

First, find the number of bracelets she's able to make with her string. She has 5/8 of a yard and uses 1/5 per bracelet. To divide the number of yards she has by the number she uses, multiply 5/8 by the reciprocal of 1/5 (5/1).

5/8 * 5/1 = 25/8

25/8 is 3.12500, which is the number of bracelets she can make. It rounds down to 3 since she can't make 0.12500 bracelets.

Now, find how many charms she used. 3 bracelets * 12 charms each is 36 charms in total.

So she used 36/96 of her charms. This can be simplified to 3/8.

Answer:

37/96 hazel has

Step-by-step explanation:

1/5 times 12=60

so Hazel uses 1 yardd for 60 charms, so for 5/8 yard Hazel would use 5/8×60=37.5.

since Hazel isn't able to use a fraction of a charm, she would use 37 charms

37/96 Charms Hazel has

What is the measure of m<3
A. 58 degrees
B. 122 degrees
C. 116 degrees
D. 64 degrees​

Answers

Hello!

[tex]\large\boxed{\text{ D. 64 degrees}}[/tex]

Angles in a triangle sum up to 180°, so:

180° = 58° + 58° + m∠3

Combine and subtract:

180° = 116° + m∠3

64° = m∠3

Thus, the answer is D.

A survey revealed that 20% of workers at a company were satisfied with their job. If 30 workers selected this option. How many total workers are at the company? Use the model below to help you solve the question.

Answers

Answer:

150 workers are at the company

Step-by-step explanation:

If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so

20% * 5 = 100%

30 * 5 = 150

so 100% of the workers is equal to 150 workers

The age of the oldest sibling is 15 years old.

What is consecutive number?

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.

Here, let the age of youngest sibling be x years

              the age of middle sibling be (x+1) years

              the age of oldest sibling be (x+2) years

According to question,

        x + (x+1) + (x+2) = 42

          3x + 3 = 42

           3x = 39

             x = 13

Thus, the age of the oldest sibling is (x+ 2) years = 15 years old.
