Jack bought five bracelets and one necklace
for $24. Jill bought six bracelets and four
necklaces for $54. Write an equation for each
person. Use b to represent the number of
bracelets and n to represent the number of
necklaces
Answer:
Jack: 4 x 6 = 24
Jill: 5.4 x 10 = 54
Step-by-step explanation:
Jack:
5 + 1 = 6
24 ÷ 6 = 4
4 = $4 per item
Jill:
6 + 4 = 10
54 ÷ 10 = 5.4

What is the coefficient of the x to the power of 4 y to the power of 3 term in the expansion of (x-2y) the the power of 7?
Answer:
-280
Step-by-step explanation:
step-by-step explanation: so ( x-2y)^7 expanded is: x^7-14 x^6y+84x^5y^2-280x^4y^3+560x^3 y^4-672x^2y^5+448xy^6-128y^7. The x^4y^3 term would then be -280 x^4y^3,meaning the coefficient (the number before the variables) here is 280
Determine the most appropriate model for the data in the table.
Please help
Answer:
An exponential model will be the best for the data.
Step-by-step explanation:
If you chart this data (either using a calculator, excel, or an online tool like desmos), it is clear that the curve is exponential.
Furthermore, if you run regression, you can find that the curve [tex]4*2^x[/tex] fits the data quite nicely.
Round 0.293263 to the ten thousandths place
Answer:
0.293263 rounded to the ten thousandths place
=0.2933
Answer:
0.2933
Step-by-step explanation:
0.293263 is the decimal you have to round.
0.293263 (the first 2 is in the tenths place)
0.293263 (the 9 is in the hundredths place)
0.293263 (the first 3 is in the thousandths place)
0.293263 (the second 2 is in the ten-thousandths place)
0.293263 (the 6 is in the hundred-thousandths place)
0.293263 (the second 3 is in the millionths place)
They tell you to round the decimal to the ten thousandths place.
The second 2 is in the ten-thousandth place (0.293263).
To round digits you look at the number to its right, if it is 5-9 you round the number up, if it is 0-9 you leave the number as it is.
The number to the right of the number we're rounding (the 2 in the ten-thousands place) is a 6, 6 is a 5-9 number so we round the ten-thousands place digit up 1 number, (from 2 to 3).
And we have our rounded number 0.2933

If x – 4 is a factor of x2 + 8x + k, what is the value of k?
Answer:
k ±16
Step-by-step explanation:
Evaluate x^2 + 8 x + k where x = -4:
x^2 + 8 x + k = k - 4 8 + (-4)^2
(-4)^2 = 16:
k - 4 8 + 16
8 (-4) = -32:
k + -32 + 16
Grouping like terms, k - 32 + 16 = k + (16 - 32):
k + (16 - 32)
16 - 32 = -16:
Answer: k ±16
Answer:
The answer is
k=−11
Explanation:
Let
f(x)=x^3−6x62+kx+10
If (x+2)is a factor
Then,
f(-2)=0
f(−2)= −8− 24 − 2k + 10= 0
2k=-22

all those numbers are confusing, but this is what i get from the picture
triangle area formula = 1/2 base * height
rectangle area formula = L * W
AB = 1/2 base * height, = 1/2 * 9 * 4, = 18
ab is the same as AB =18

The size of the angle QUP in the system formed by the equilateral triangle QUR, the equilateral triangle PUT and the square RUTS is equal to 150°.
How to determine a missing angle within a geometrical system
By Euclidean geometry we know that squares are quadrilaterals with four sides of equal length and four right angles and triangles are equilateral when its three sides have equal length and three angles with a measure of 60°. In addition, a complete revolution has a measure of 360°.
Finally, we must solve the following equation for the angle QUP:
m∠QUR + m∠QUP + m∠PUT + m∠RUT = 360
60 + m∠QUP + 60 + 90 = 360
m∠QUP + 210 = 360
m∠QUP = 150

Find the volume of the cone shown as a decimal rounded to the tenth. 22m 12m
Answer:
b
Step-by-step explanation:
the volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius , h is the height )
here diameter = 12 , so r = 12 ÷ 2 = 6 and h = 22 , then
V = [tex]\frac{1}{3}[/tex]π × 6² × 22
= [tex]\frac{1}{3}[/tex]π × 36 × 22
= [tex]\frac{1}{3}[/tex]π × 792 ( cancel 3 and 792 by 3 )
= π × 264

Answer:
3
Step-by-step explanation:
4f-3 = 5f-6
First I would try to get the f's on one side and the other numbers on the other, to do this you woudl have to add 6 to both sides
4f -3 = 5f -6
+6 +6
Making it into: 4f + 3 = 5f
Now to get the 4f on the other side we will have to subtract it from both sides
4f +3 = 5f
-4f -4f
3= f (Remember you do not have to put the 1, making 3 your answer)
