Answer:

x > 4.5

Step-by-step explanation:

Given the inequality :

14.4x - 28.2 > 36.6

Collect like terms

14.4x > 36.6 + 28.2

14.4x > 64.8

Divide both sides by 14.4

x > 64.8 / 14.4

x > 4.5

Answer:

-19

Step-by-step explanation:

36 is 24 less than 60 so that means they subtracted to get 36 so subtract 24 from five and boom -19

The answer is 1/4. And how I got that is I divided both sides by 5, and I got the answer 1/4. I hope this helps! :)

Answer:

The first angle is the smallest

Step-by-step explanation:

Step one:

given data

Angle 1= x+37

Angle 2= 90

angle 3= x+67

We know that the sum of angle in a triangle is 180

so

x+3+90+x+67= 180

collect like terms

2x+160= 180

2x=180-160

2x= 20

divide both sides by 2

x= 10

Step two:

so

Angle 1= 10+37= 47 °

Angle 2= 90= 90

angle 3= 10+67= 77 °

Answer:

20/54

Step-by-step explanation:

Answer:

23º = x

Step-by-step explanation:

One straight line is ALWAYS 180º

(called a linear pair)

So your equation is

157º + x = 180

subtract x on both sides

and you get

23º

That is a question about angles.

The first thing that we should to note is that a line do a straight angle. A straight angle is an 180° angle.

So, we can say that the sum of the angle a and the angle of 157° is equal to a straight angle. Let's make and solve a equation:

[tex]a + 157 = 180\\a = 180 - 57\\a = 23[/tex]

Therefore, the missing angle is 23°.

I hope I've helped. :D

Answer:

FV= $4,786.01

Step-by-step explanation:

Giving the following information:

Initial deposit (FV)= $4,300

Number of periods (n)= 2 semesters

First, we need to calculate the semi-annual interest rate:

Semi-annual interest rate= 0.11/2= 0.055

Now, to determine the future value, we need to use the following formula:

FV= PV*(1+i)^n

FV= 4,300*(1.055^2)

FV= $4,786.01

Answer:

$64.12

Step-by-step explanation:

Michael is purchasing back to school supplies. He gets a math workbook for $19.88, a calculator for $35.97, and a pack of pencils for $8.27. How much did he spend on school supplies?

The amount that he spent on school supplies is calculated as:

Cost of math workbook + Cost of a calculator for + Cost of a pack of pencils for

$19.88 + $35.97 + $8.27

= $64.12

Answer:

Answer:

3[tex]\sqrt{3}[/tex] and [tex]\sqrt{7}[/tex]

Step-by-step explanation:

Simplifying surds is similar to collecting like terms in algebra.

If the surds have the same value then collect them by adding/ subtracting their coefficients.

(a)

[tex]\sqrt{3}[/tex] (7 - 2 + 1 - 3)

= [tex]\sqrt{3}[/tex] (3)

= 3[tex]\sqrt{3}[/tex]

(b)

[tex]\sqrt{7}[/tex] (5 + 4 - 8)

= [tex]\sqrt{7}[/tex] (1)

= [tex]\sqrt{7}[/tex]

Answer: C = -6.3

Step-by-step explanation:

Answer: 276

Step-by-step explanation:

multiply 1/3 by 4/4 to make it similar to 5/12 that way you can add them. because the denominator is different from each other you can’t add them. once you do that you get 4/12, you then add 5/12 and that equals 9/12. in order to get to 12/12 you need 3/12 more. this 3/12 represents the 69 guest that chose vegetarian. the 5/12 represents the the guest who chose chicken and the 4/12 represents the ones who chose beef. now that you know 69 people is the same as 3/12 of all the guest. you then realize that 9 is divisible by 3. so you multiply 69 by 3 because 3 goes into 9 3 times. which gives you 207. 207 represents 9/12. and we already know 69 represents 3/12. so you add them together and get 276. sorry if that was confusing but that’s the best way i can explain it.

Answer:

Dimes: 10 dimes

Nickles: 6 nickels.

Step-by-step explanation:

Dimes: 10 x 0.10 = 1.00

Nickels: 6 x 0.05 = 0.30

$1.00 + $0.30 = 1.30

Answer:

755.16 cm³

Step-by-step explanation:

We can separate this into two parts -- the bottom rectangular prism and the top triangular prism.

The volume of the bottom part is 12*4*14 = 672 cm³

For the triangular prism, we have an equilateral triangle, with sides 4cm, as well as a length of 12cm. We can find the area of the triangle and multiply it by 12 for our answer. The area of an equilateral triangle is [tex]\frac{\sqrt{3} }{4} 4^{2}[/tex], which is approximately 6.83 -- we can multiply that by 12 to get 83.16 cm³

Add these 2 up to get 755.16 cm³ as our answer
