Answer: 2.3 × 0.4 = 0.92 .

2.3 × 1 = 2.3

0.92 + 2.3 = 3.22

Step-by-step explanation:

When decimal points are left out until the end, you can count the number of decimal places to the right of the decimals in the factors and then insert the decimal in the product, counting places right to left.

The factor 2.3 has one decimal place. The factor 0.4 has one decimal place.

Thats a total of 2.

92 becomes .92 when the decimal is inserted two places to the left.

230 becomes 2.30 when the decimal is inserted two places to the left.

If 15 x 2=30 and 8x2=16 not 18 it’s incorrect

Answer:

No, Lauren is not correct because the ratio is actually 15:8 this is because the ratio represents the number of boys to girls. The only way to show this equation in ratio notation would to say 15:8. Therefore Lauren is incorrect.

Which values for x make this inequality false?

Answers

Answer:

0.25, 1/4, 0.5, 1/2

Step-by-step explanation:

The inequality reads x is less than or equal to 1/5

**A good way to remember what the symbols mean is by saying the following:

"If it's coming from the left then it's less than, coming from the right, it's greater than.."

So in order to make this inequality false, we would need to select values that are greater than 1/5.

1/5 in decimal form is 0.20

So we need values that are greater than 0.20

The following values are greater than 0.20 (or 1/5):

0.25, 1/4, 0.5, and 1/2..

2/10 and 0.2 equal 1/5, so they are not the answer

Hey there!

“Which value(s) for x make this inequality false x ≤ 1/5

1/5 = 0.20 (as a decimal) ; 20% (as a percentage)

So, “0.25”, “1/2” , “1/4” , & “0.5” is most likely your answer because 2/10 & 0.20 is EQUIVALENT to 1/5

Answer: “0.25”, “1/2” , “1/4” , & “0.5”

Good luck on your assignment and enjoy your day!

A.
$23.86x + $0.17 = $28.11

B.
$0.17x - $23.86 = $28.11

C.
$0.17x + $23.86 = $28.11

D.
$23.86x - $0.17 = $28.11

GIVING BRAIN PLZ ASAP

Answers

Answer: It's C believe me

Explanation: x goes on the number that will be in this case 0.17 since it changes monthly or whatever. Then it's telling you that they already charge him 23.86 dollars so you just add it and of course 28.11 it's the total. Sry if it make sense.

The answer is C because if they charge the additional fee of 0.17 for each text they would be multiplying 0.17 for each time then adding on 23.86

if the ratio of dogs to cats is 1 to 2 and there is a total of 21 animals how many are dogs

Answers

Answer:

Step-by-step explanation:

Let cats = x and dogs = y

and given conditions are ,

dog: cat= 1:2

y:x=1:2

y/x = 1/2

x=2y

also given that

total animals = 21

x+ y=21 putt x=2y we get

2y +y =21

3y = 21

y = 7 Dogs

putt y = 7 in above equation we get

x+7=21

x=14 Cats

There are 7 dogs and 14 cats

Every one dog there are two cats 1:2
Also could be written as (cats) 7:12 (dogs)

Answer:

∡ABC=55°

Step-by-step explanation:

Step 1: Identify all angles

∠A=(x+45)°

∠B=(6x+5)°

∠C=(3x)°

∠ABC=(180-∠B)°=(180-(6x+5))°

Step 2: Use the Triangle Angle Sum Theorem

∠A+∠ABC+∠C=180°

(x+45)+(180-(6x+5))+(3x)=180

x+45+180-6x-5+3x=180

-2x+45+180-5=180

-2x+45-5=0

-2x+40=0

-2x=-40

x=20

Step 3: Plug in x=20 for ∠ABC

∠ABC=(180-(6x+5))°

(180-6(20)-5)°

(180-120-5)°

(60-5)°

55°

So ∡ABC=55°

Answer:

∡ABC=55°

Step-by-step explanation:

Step 1: Identify all angles

∠A=(x+45)°

∠B=(6x+5)°

∠C=(3x)°

∠ABC=(180-∠B)°=(180-(6x+5))°

Step 2: Use the Triangle Angle Sum Theorem

∠A+∠ABC+∠C=180°

(x+45)+(180-(6x+5))+(3x)=180

x+45+180-6x-5+3x=180

-2x+45+180-5=180

-2x+45-5=0

-2x+40=0

-2x=-40

x=20

Step 3: Plug in x=20 for ∠ABC

∠ABC=(180-(6x+5))°

(180-6(20)-5)°

(180-120-5)°

(60-5)°

55°

So ∡ABC=55°
