Which expression is equivalent to the perimeter of the given triangle

The formula for percent error is:

((Approximate value -  exact value) / exact value) x 100

1) 14-12 = 2

2/12 = 0.1666

0.166 x 100 = 16.7%  (Rounded to nearest tenth)

2) 231 - 215 = 16

16/215 = 0.74419

0.74419 x 100 = 7.4419% ( Round as needed)

3) 17.1 - 16.5 = 0.6

0.6/16.5 = 0.36364

0.36364 x 100 = 3.6364% (Round off as needed)

4)  1081 - 1150 = -69

-69/1150 = -0.06

-0.06 x 100 = -6% = 6% error

Answer:

1) 85.7%

2) 93%

3) 96.5%

4) 94%

Step-by-step explanation:

Sorry if any of these are wrong. I used the formula a/w= p/100. a is the part, w is the whole and p is the percent.

Answer:

A. should be your answer

Step-by-step explanation:

Because Audrey spent $112 dollars and had 96$ dollars left, this represents the situation m - $112 = $96.

Where m is the money Audrey collected for the food drive. She spent 112 dollars so that is deducted from her total, which is equal to $96 because that is the amount she had left.

When you add the amount she had left and the money she spent, you get the money she started with because the money spent is what is deducted from the initial amount to get the total.

Thus m = $208

because $112 + $96 = $208.

Answer:

B: 10 cups of flour with 4 teaspoons of vanilla

Step-by-step explanation:

The answer is B because the original ratio is 5 flour: 2 vanilla. Then the new measurement that still follows that rule must be able to multiply the flour and vanilla. 5 times 2 is 10 and 2 times 2 is 4. I multiplied by two and got 10 flour: 2 vanilla.

Answer:

The numbers or measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates

P.S I TRIED MY BEST

Step-by-step explanation:

The required values of ratios are 9/16,3/2, 7/6 and 1/12 respectively. The only false option is (c).

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

All the options are examined one by one as follows,

(a) The ratio of 5/8 to 10/9 is given as,

5/8 : 10/9

= (5/8) ÷ (10/9)

= 5/8 × 9/10

= 9/16

Thus, it is true.

(b) The ratio of  4/7 ∶ 8/21 is given as,

4/7 ∶ 8/21

= (4/7) ÷ (8/21)

= 4/7 × 21/8

= 3/2

Thus, it is true.

(c) The unit rate of 7/9 and 2/3 equivalent to the ratio given below,

7/9 : 2/3

= 7/9 ÷ 2/3

= 7/9 × 3/2

= 7/6

Thus, it is false.

(d) The unit rate of 9/16 and 27/4 equivalent to the ratio given below,

9/16 : 27/4

= 9/16 ÷ 27/4

= 9/16 × 4/27

= 1/12

Thus, it is true.

Hence, the ratios for the given options are obtained as 9/16,3/2, 7/6 and 1/12 respectively.

Answer:Group of answer choices

Step-by-step explanation:

What you first want to do is like and unlike terms so basically liketerms are terms withthe same sign and unlike terms are terms with diferent signs for instinse 3g and 2g are like terms so -33 and -9 and -9 and 9 are unlike terms so you just have to find the like and unlike terms to answer the question!

Answer: -9

Step-by-step explanation: Let's solve your equation step-by-step.

3g+15−12+3−2g+4=1

Step 1: Simplify both sides of the equation.

3g+15−12+3−2g+4=1

3g+15+−12+3+−2g+4=1

(3g+−2g)+(15+−12+3+4)=1 (Combine Like Terms)

g+10=1

g+10=1

Step 2: Subtract 10 from both sides.

g+10−10=1−10

g=−9

So the answer is g=-9

Answer:

t = 8

Step-by-step explanation:

[tex]\frac{1}{4}t - 6 = -4\\ +6 \\^{*4} \frac{1}{4}t = 2^{*4} \\t = 8[/tex]

The value of t in the given expression is t = 8

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression we need to simplify it for t,

The expression is 1/4t - 6 = -4

So, add 6 to both sides,

1/4 t -6 + 6 = -4 + 6

1/4 t = 2

Multiply by 4 to each side,

1/4 x 4 t = 2 x 4

t = 8

Hence, the value of t in the expression given is 8

Answer:

the answer its c 122 is angle 1

Answer:

A. 32

Step-by-step explanation:

The two angles are equal to each other so you can set them equal and solve

2x+57=6x-71

Add 71 to both sides

2x+57+71=6x+0

2x+128=6x

Subtract 2x from both sides

128=6x-2x

128=4x

Divide 4 from both sides

128/4=x

Answer:

12 of the 5 cents stamps,

20 of the 6 cents stamps

15 of the 8 cents stamps

10 of the 30 cents stamps.

Step-by-step explanation:

Let's name:

x = number of 5 cent stamps,

w = number of 6 cent stamps,

y = number of 8 cent stamps,

z = number of 30 cent stamps,

Create the following system of equations based on the info provided:

z + 5 = y

w = 2 * z

x = 12

600 = 5 (12) + 6 w + 8 y + 30 z

replace everything in terms of "z":

600 = 60 + 6 (2 * z) + 8 (z + 5) + 30 z

540 = 12 z + 8 z + 40 + 30 z

500 = 50 z

z = 10

and now we can find the rest:

y = 5 + 10 = 15

w = 2 * 10 = 20

Therefore there are:

12 of the 5 cents stamps,

20 of the 6 cents stamps

15 of the 8 cents stamps

10 of the 30 cents stamps.

Answer:

$8
