0.12 because it equals to 12% where 1.2% equals to 0.012

Answer 2

Answer: 11

Step-by-step explanation:

Out of the 3 choices, the last two both give decimals less than one, so we know they won't be greater than 11.

4. IN YOUR OWN WORDS How does the decimal point move when you rewrite a percent as a decimal and when you rewrite a decimal as a percent?

Answers

Answer:

The decimal point moves two places to the left when you rewrite the percentage as a decimal. When you rewrite the decimal as a percentage you move the decimal point two places to the right.

the decimal move 2 places to the left. for example if it was 62% itd be 62. but id move it to placed to the left so itd be .62 and for a decimal youd move it to the right 2 times so if it was .634 itd be 63.4 %

19. Ken bought 8 markers and 20 pens. Each marker cost $2.45. He gave the cashier $100 and received $26 change. What was the cost of each pen?

Answers

Answer:
$2.28
Explanation:
2.45 multiplied by 8 is 19.6, 19.6 plus 26 is 45.6. 45.6 divided by 20 is 2.28

Answer:

Each pen costs $2.72

Step-by-step explanation:

100 - 26 = $74 spent total

8 x 2.45 = $19.60 spent on markers

74 - 19.60 = $54.40 spent on pens

54.40/20 = $2.72 per pen

Answers

Answer:

its B

Step-by-step explanation:

because if you flip e to the other side of the y-axis you'll get (2,4) and do the same with the letters and that's your answer.

Answer:

B. C'(3 , 0) , D'(7 , 1) , E'(2 , 4)

Step-by-step explanation:

reflecting the point A(x , y) across the y-axis gives us the point A'(-x , y)

Then

The image of E(-2 , 4) is E'(2 , 4)

The image of C(-3 , 0) is C'(3 , 0)

The image of D(-7 , 1) is D'(7 , 1)

Therefore

The correct answer is option B.

A vocational school admits 4 out of every 10 people who apply for admission. One year 640 students were admitted. How many people applied for admission?

Answers

Answer:256

Step-by-step explanation:640/10 equal 64

so then multiply 64x4 equal 256 so 256/640

The number of students who applied for admission is 1600

Using the values given in our Calculation:

Total number of admitted students = 640Admission proportion ; 4 out of 10

Calculating the proportion of students who gets admitted :

4/10 = 0.4

To obtain the number that would get admitted from 640 students, divide the total number of applications by the proportion

Now we have :

640 / 0.4 = 1600

Therefore, only 1600 students applied .

In triangle ABC, AB=BC, AC=10cm. From point D, which is in the middle of AB, perpendicular bisector DE is drawn to side BC and intersects it at point E. A segment is then drawn from E to A. The perimeter of triangle ABC is equal to 40 cm. Find the perimeter of △AEC.

Answers

Answer:

Step-by-step explanation:

We are given that the perpendicular bisector of side AB of ∆ABC intersects side BC at point D.

this means that side AE=BE.

Also, we could clear; ly observe that

ΔBED≅ΔAED

( since AE=BE, side ED common, ∠BED=∠AED

so by SAS congruency, the two triangles are congruent)

Now we are given that:

the perimeter of ∆ABC is 12 cm larger than the perimeter of ∆ACD.

i.e. AB+AC+BC=AC+AD+CD+12

AB+BC=AD+CD+12

as AD=BD

this means that AD+CD=BD+CD=BC

AB+BC=BC+12

AB=12

mark as brainliest

The perimeter of 40 cm. and lengths of two sides of ∆ABC where side AC is 10 cm gives;

The perimeter of ∆AEC is 25 centimeters

How can the perimeter of the formed ∆AEC be found?

Given:

AB = BC

AC = 10 cm.

The perimeter of ∆ABC = 40 cm.

Therefore;

∆ABC is an isosceles triangle

AB + BC + AC = 40

AB + AB + 10 = 40 by substitution property of equality

2 × AB = 40 - 10 = 30

AB = 30 ÷ 2 = 15

AB = BC = 15 cm.

Using the rule of cosines, we have;

10² = 15² + 15² - 2×15×15 × cos(A)

cos(A) = (15² + 15² - 10²) ÷ (2×15×15)

A = arccos (350 ÷ 450) ≈ 51.06°

<BED ≈ 180° - (90° + 51.06°) = 38.94°

DB = AB ÷ 2

Therefore;

DB = 15 ÷ 2 = 7.5

From the rule of sines, we have;

DE/sin(51.06°) = 7.5/sin(38.94°)

DE = 7.5/sin(38.94°) × sin(51.06°) ≈ 9.28

According to Pythagorean theorem, we have;

BE ≈ √(7.5² + 9.28²) ≈ 11.93

Similarly, we have;

AE ≈ √(7.5² + 9.28²) ≈ 11.93

EC ≈ 15 - 11.93 = 3.068

Perimeter of ∆AEC = AE + EC + AC

Which gives;

The perimeter of ∆AEC = 11.93 + 3.068 + 10 ≈ 25

The perimeter of ∆AEC = 25 cm

Answers

When comparing fractions, you can multiply or divide to find equivalent fractions.

Number 1: If I were to multiply 5 to 45, I would have to do the same to the numerator of the fraction. 45/5 = 9. So we know now that 5 times 9 equals 45. Lets do that to the numerator also. 4 times 9 equals 36 so 4/5 times nine is 32/45.

So yes, this would be equivalent.

Number 2: 7/8 times 4 equals 28/32

Yes, this would be equivalent.

Number 3: 10 times 10 is 100, 1 times ten is NOT 30.
