Step-by-step explanation:
2 = q , what is the value of q?Maggie says that if the expression was 12÷3to the second power, you would divide before simplifying 3 to the second power. Is she right? Explain
Answer:
Maggie is incorrect.
Step-by-step explanation:
PEMDAS tells us the order of operations and the steps of solving a mathematical statement. It states that exponents must be performed before multiplication or division.
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Therefore, to solve 12÷3² correctly, 3² needs to be simplified to 9 before dividing.
I hope this helps!

Step-by-step explanation:
Two high schools are going on a field trip. One rents 8 vans and 9 buses for 228 students. The other rents 4 vans and 5 buses for 124 students. How many people can you fit in a van? How many people can you fit in a bus?
Answer:
No. pp you can fit in a van: 6,
No. pp you can fit in a bus: 20
Step-by-step explanation:
Let v = # of pp in vans, and let b = # of pp in buses:
8v + 9b = 228,
4v + 5b = 124
If we solve this system of equations by substitution, we isolate the first eq. for v and then substitute into the bottom eq:
v = 228-9b/8,
Substitute v = 228-9b/8 into bottom eq:
[4 * 228-9b/8 + 5b = 125]
[228+b/2=124]
[228+b = 248]
[b = 20]
Now substitute 20 to find no. of pp in the vans:
v = 228 - 9(20)/8 = 228 - 180/8 = 48/8 = 6
A donut shop made 32 donuts with frosting and 18 donuts without frosting. What is the ratio of the number of donuts with frosting to the number of donuts without frosting?
Answer:
16 to 9
Step-by-step explanation:
Represent donut with frosting with D1 and donut without frosting with D2.
So, we have:
[tex]D_1 = 32[/tex]
[tex]D_2 = 18[/tex]
Required
Find the ratio of D1 to D2
This is calculated as:
[tex]D_1 : D_2[/tex]
Substitute values for D1 and D2
[tex]D_1 : D_2 = 32 : 18[/tex]
Divide by 2
[tex]D_1 : D_2 = 32/2 : 18/2[/tex]
[tex]D_1 : D_2 = 16 : 9[/tex]
The ratio of donuts with frosting to donuts without is 16 to 9
Answer:
16 to 19
Step-by-step explanation:
find the exact value of the composite function show work
Answer:
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]
Step-by-step explanation:
This function can be written as:
[tex]\frac{1}{cos(sin^{-1}(\frac{1}{2x})) }[/tex]
[tex]sin^{-1}(\frac{1}{2x})[/tex] means the angle whose sine is 1/(2x). This implies that the denominator is the cosine of the angle whose sine is 1/(2x)
Think of a right triangle and consider the angle with this sine. Then the opposite side has length 1 and the hypotenuse has length 2x. The Pythagorean theorem then implies that the adjacent side is
[tex]\sqrt{4x^{2} -1}[/tex]
The cosine of the angle is adjacent over hypotenuse, so the cosine is
[tex]\frac{\sqrt{4x^{2} -1}}{2x}[/tex]
The secant is the inverse of the cosine, so the answer is
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]
Multiply the two polynomials and write your answer in standard form – 3x (4x - 2)
Answer:
-12x^2+6x
Step-by-step explanation:
-3x(4x-2)
-12x^2+6x
The standard form of the polynomial is -12x² +6x.
What is a polynomial?A polynomial is an equation made up of exponents, constants, and variables that is combined using mathematical operations including addition, subtraction, multiplication, and division.
The given expression is – 3x (4x - 2)
Solving further,
–3x (4x - 2)
=-12x² +6x.
The standard form of the polynomial is -12x² +6x after multiplying – 3x (4x - 2)

pls help me ASAP!! what is the surface area of this design? a) 288in b) 256in c) 96in d) 160in
Answer:
b) 256 inches
Step-by-step explanation:
8x5x2 = 80 (top & bottom)
8x5x2 = 80 (front & back)
8x8x2 = 128 (gross area of 2 sides)
4x4x2 =32 (delete this for side cutouts) Guessing the cutoff dimension on
left side is 4m inch.
80+80+128-32 = 256 inches

Find the value of x.
Answer:
C
Step-by-step explanation:
We're given the adjecent and we're looking for the hypotenuse so we'll have to use cosine ratio.
11 / cos 38 = 13.959.....
x = 14.0
We can also use the tangent ratio to look for the opposite and then use pythagorean to find the hypotenuse.
11(tan 38) = 8.594......
8.594.....² + 11² = 194.859......
Square root of 194.859..... = 13.959.......

1.If the part is bigger than the whole, what must be true about the percent 2.If the part is smaller than the whole, what must be true about the percent ?
Answer:
1.greater than 100%
2.less than 100%
Step-by-step explanation:
A whole is represented by the percentage 100%. Therefore, if the part being targeted is bigger than the whole then it would be greater than 100%. While, if the part is smaller than the whole then it would be less than 100%. This is always true in every scenario due to "a whole" being represented as the entirety of the object or data in question, which is why in numerical value it is shown as being 100%

Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
help quickly
Answer:
£3692
Step-by-step explanation:
A = p(1 + r/n)^nt
Where,
A = future value
P = principal = £2350
r = interest rate = 4.2% = 0.042
n = number of periods = 1(annual)
t = time = 4 years
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Total years = 10
Remaining years = 10 - 4
= 6 years
Remaining 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692
