Answer:

a = 195 m , b = 180 m , c = 75 m  

Step-by-step explanation:

Let "a,b and c" be the sides of the triangle in the ration - 13:12:5

therefore , a:b:c = 13:12:5 => a = 13x , b = 12x , and c = 5x

therefore , Perimeter = 13x + 12x + 5x = 450

=> 30x = 450

=> x = 15

therefore , a = 13 x 15

b = 12 x 15 and

c = 5 x 15

hence , a = 195 m , b = 160 m and c = 75 m

Answer:

a = undefined/no real solution

Step-by-step explanation:

Expand

24a - 22 = -4 + 24a

24a - 24a = -4 + 22

0a = 18

a = undefined/no real solution (when something is divided by 0 it becomes undefined)

The equation 24a - 22 = -4(1 - 6a) have no solution for the variable "a".

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Given:

equation 24a - 22 = -4(1 - 6a)

1. Distribute the -4 to the terms inside the parentheses:

  24a - 22 = -4 + 24a

2. Simplify the equation by combining like terms:

  24a - 22 = 24a - 4

3. Rearrange the equation by moving all the terms involving "a" to one side and the constant terms to the other side:

  24a - 24a = -4 + 22

4. Simplify  24a - 24a = -4 + 22:

  0 = 18

The equation 0 = 18 is not true, which means there is no solution.

Answer:

D) Emerson must earn at least a 94 on his final test to earn an “A” in his class

Step-by-step explanation:

We calculate this using mean in this format:

Test Scores / # of Test ≥ 90 (which is an A)

Substitute:

(92 + 86 + 88)+ x / 4 ≥ 90

Add:

266 + x / 4 ≥ 90

Get Rid of the Denominator:

(4) 266 + x / 4 ≥ 90 (4)

Multiply:

266 + x ≥ 360

Isolate x (Subtract 266 From Both Sides):

x ≥ 94

This means that x (His final test score) has to be greater than (above) or equal to 94. A term for greater than or equal to is “at least.” Hope this helps :)

Answer:

The payment for driving 80 miles is $78

Step-by-step explanation:

Mathematical model

Mathematical models are used in disciplines like natural sciences and engineering, among many others.

The data provided in the question allows building a model for the charges of the car rental, knowing there are two fees:

A fixed charge of $50

A variable charge or $0.35 per mile driven.

Part A

Using m as the number of miles driven for the day, the model for the payment for the car rental is:

P(m)=50+0.35m

Part B

Find the payment if the car is driven m=80 miles:

P(80)=50+0.35*80

P(80)=50+28=78

Answer:

f(29) = - [tex]\frac{9}{290}[/tex]

Step-by-step explanation:

Step 1: substitute f(29) into the equation.

f(29) = 2(29 - 20)²⁻³

29 replaces x.

Step 2: simplify the exponent

f(29) = 2(29 - 20)⁻¹

2-3 is -1, so the exponent is -1

Step 3: distribute the exponent to the parentheses

f(29) = 2([tex]\frac{1}{29}[/tex] - [tex]\frac{1}{20}[/tex])

Since the exponent is a negative one, basically make it a fraction with the base as the denominator and the exponent as a numerator. I don't know too much about negative exponents, but this is how to factor in a -1.

Step 4: Distribute.

f(29) = [tex]\frac{2}{29} -\frac{2}{20}[/tex]

Step 5: Simplify before finding a common denominator (2/20 cancels out)

f(29) = 2/29 - 1/10

Step 6: Find a common denominator (290)

f(29) = [tex]\frac{20}{290}[/tex] - [tex]\frac{29}{290}[/tex]

Step 7: Simplify

f(29) = - [tex]\frac{9}{290}[/tex]

Answer:

x= -31

Step-by-step explanation:

Let's solve your equation step-by-step.

3(2x−14)+x=15−(−9x−5)

Step 1: Simplify both sides of the equation.

3(2x−14)+x=15−(−9x−5)

3(2x−14)+x=15+−1(−9x−5)(Distribute the Negative Sign)

3(2x−14)+x=15+−1(−9x)+(−1)(−5)

3(2x−14)+x=15+9x+5

(3)(2x)+(3)(−14)+x=15+9x+5(Distribute)

6x+−42+x=15+9x+5

(6x+x)+(−42)=(9x)+(15+5)(Combine Like Terms)

7x+−42=9x+20

7x−42=9x+20

Step 2: Subtract 9x from both sides.

7x−42−9x=9x+20−9x

−2x−42=20

Step 3: Add 42 to both sides.

−2x−42+42=20+42

−2x=62

Step 4: Divide both sides by -2.

The length of the south side of the park is 142⁶/₇%  of the length of the north side. The correct option is H.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the length of the south side of the garden is 40 inches and the length of the north side of the garden is 28 inches.

The percentage of the length of the south side of the park to the length of the north side will be calculated as:-

Percentage = 40 / 28

Percentage = 142⁶/₇%  

Therefore, the length of the south side of the park is 142⁶/₇%  of the length of the north side. The correct option is H.

The value of (3.9 × 10⁻³) + 0.0026 in scientific notation is 6.5 × 10⁻³.

Decimal numbers are numbers which has basically a whole number part and a fractional or decimal part after a point called decimal point.

Decimal number system describes the base 10 number system.

Given are numbers 3.9 × 10⁻³ and 0.0026 added together.

We have to do it in scientific notation.

0.0026 can be written as 2.6 × 10⁻³.

Adding these two numbers together, and taking the common term,

(3.9 × 10⁻³) + (2.6 × 10⁻³) = (10⁻³) (3.9 + 2.6)

                                        = (10⁻³) (6.5)

                                        = 6.5 × 10⁻³

Hence the answer of the sum of (3.9 × 10⁻³) + 0.0026 is 6.5 × 10⁻³ in scientific notation.

Answer:

Step-by-step explanation: 7 miles: 3/4 hour, 9/8 miles: 5/6 hour, and 4 miles: 3 and 1/3 hour.

hope this helps !! <3

The ratios that have a unit rate is 9/8 miles:5/6hours and 7miles: 3/4 hours

Unit rate is the ratio of the distance travelled o the time taken.

For us to know which of the ratios has a unit rate greater than 1, we need to divide the distance by the time as shown;

If distance = 9/8 miles and time = 5/6 hours

[tex]Unit \ rate =\frac{(9/8)}{(5/6)}\\Unit \ rate =\frac{9}{8} \times \frac{6}{5}\\Unit \ rate = \frac{54}{40} \\Unit \ rate =1.35 miles/hour[/tex]

Hence the ratio that has a unit rate is 9/8 miles:5/6hours

If distance = 7 miles and time = 3/4 hours

[tex]Unit \ rate =\frac{7}{(3/4)}\\Unit \ rate =\7 \times \frac{4}{3}\\Unit \ rate = \frac{28}{3} \\Unit \ rate = 9.33miles/hour[/tex]

Hence the ratio that has a unit rate is 7 miles:3/4hours

This is really just a simple division question.  All we have to do to solve the first half is divide 332 by 15:

[tex]332 / 15 = 22.133333333[/tex]

We'll want to round that up to 23, because it seems they're asking for integers here.

For the next part of the question, all we have to do is double the result of the last operation and round that number up as well:

[tex]22.13333333 *2 = 44.2666667[/tex]

Which rounded gives us 45.

Answer:

Samuel will need 23 pieces of wood.

Theresa will need 46 pieces of wood.

Step-by-step explanation:

To find how many total pieces Samuel will need, we have to divide 332 feet into 15, since each piece of wood is equivalent to 15 feet:

[tex]332[/tex] ÷ [tex]15=22.1333[/tex]

Samuel can't have a portion of wood, the wood pieces he has must be represented as a whole number. We have to round up to 23 pieces of wood.

Samuel will need 23 pieces of wood to build his fence.

_

If Theresa needs twice as many feet as wood, we have to multiply Samuel's pieces of wood by its length (15 feet):

[tex]23[/tex] × [tex]15=345[/tex]

Multiply [tex]345[/tex] by 2:

[tex]345[/tex] × [tex]2=690[/tex]

Now, divide [tex]690[/tex] by [tex]15[/tex]:

[tex]690[/tex] ÷ [tex]15[/tex]

Theresa will need 46 pieces of wood.
