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]
A bag contains 16 coins consisting of
dimes and nickels. The total value of
coins is $1.30. How many of each
type of coin are there?
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

14.4x - 28.2 > 36.6
What is the solution to the inequality? Enter the answer in the box.
X>
What’s is this??
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

Translate this sentence into an algebraic inequality.
3 more than the product of x and 12 is less than 25.
Select one:
a. 12x + 3 < 25
b. 3 > 12x – 25
c. 3 > 12(x - 25)
Answer:
Option A
Step-by-step explanation:
Lets convert each sentence into algebric inequality.
3 more than product of x & 12 :-[tex] = > 12x + 3[/tex]
Now , 12x + 3 is less than 25 :-[tex] = > 12x + 3 < 25[/tex]
If you deposit 4,300 into an account with an semi annual interest rate of 11% how much will you have after 1year
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

Find the volume of the figure in cubic centimeters.
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
The three angles of a triangle measure x+37, 90, and x+67. Find the measurement of the smallest angle in degrees.
Please help!!!
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 °
I need to know the answer to this
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.

help pls im dont know it
Answer and Step-by-step explanation:
Area of triangle:
A = [tex]\frac{bh}{2}[/tex] (Base times height, all divided by 2)
Area of Rectangle/Square
A = bh (base times height)
Triangle:
[tex]\frac{7*24}{2} = \frac{168}{2} = 84[/tex]
Rectangle:
A = 12.5 * 13 = 162.5
162.5 + 84 = 246.5
