Answer: 1 1/12 yards
Step-by-step explanation:
Since Ciara needs 2 ⅓ yards of fabric for the shawl and also needs 1 ¾ yards of fabric for the dress, the total yards needed will be:
= 2⅓ + 1¾
= 2 4/12 + 1 9/12
= 3 13/12
= 4 1/12 yards
Since she has 3 yards of fabric, the number of yards needed more will be:
= 4 1/12 - 3
= 1 1/12
Therefore, she needs 1 1/12 yards more.
An initial population of 415
ducks increases at an annual
rate of 32%. Write an
exponential function to model
the duck population.
Answer:
The exponential function to model the duck population is:
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Step-by-step explanation:
In order to calculate the duck population you can use the formula to calculate future value:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:
f(n)=415*(1+0.32)^n
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Scott was considering the equation 5 - x = 12. He said, "That seems
impossible. How can I start with 5 and subtract from it and have more than
5 as the difference?" Write a note to Scott explaining what the solution for
x is and why it is possible. *
Answer:
-7
Step-by-step explanation:
[tex]5 - x = 12 \\ 5 - 12 = x \\ - 7 = x[/tex]
it is possible because x is just a letter representing the unknown nos

Sam has 24/4 18 nickels and 36 times he wants to divide the coins into groups so that each group is worth the same amount of money what is the greatest number of groups say I'm can make using all the coins
Answer:
5 and each group would be worth $2.10
Step-by-step explanation:
Sam has 24 quarters, 18 nickels, and 36 dimes. He wants to divide the coins into groups so that each group is worth the same amount of money. What is the greatest number of groups Sam can make using all the coins?
HURRY PLEASE
Convert this monies to dollar
Quarters - 24 x 0.25 = $6
Nickels = 18 x 0.05 = $0.9
Dimes = 36 x 0.1 = $3.6
sum of these amounts = $10.50
the greatest group is 5 and each group would be worth $2.10
Mike is driving a Toyota Camry. He’s inflated his tire to the dealer-recommend level of 32 PSI. At what speed will Mike’s car start hydroplaning? With what tire pressure would his car start hydroplaning at 45 miles per hour? Use the formula v=10.35 square root p
Answer:
Part A
A speed of approximately 58.55 mph
Part B
A pressure of approximately 18.9 psi
Step-by-step explanation:
Part A
The parameter for the car are;
The tire pressure, p = 32 psi
The given equation determined for the speed, 'v', when a car will start hydroplaning is presented as follows;
v = 10.35·√p
Where;
v = The speed at which the car is moving when it will hydroplane in mpj
p = The pressure in the tire in psi
The speed at which hydro planning will start in Mike's car that has a tire pressure of 32 psi is therefore;
v = 10.35 × √(32 psi) ≈ 58.55 mph
The speed at which hydro planning will start in Mike's car that has a tire pressure of 32 psi, v ≈ 58.55 mph
Part B
When a car is moving at, v = 45 mph, we have;
v = 10.35·√p
∴ The pressure in the car tire, p = (v/10.35)²
∴ at p = 45 mph, we have;
p = (45 mph/10.35)² ≈ 18.9 psi
The tire pressure at which Mike's car start hydroplaning, p ≈ 18.9 psi

6 The interior angles of a triangle always sum to 180°. The measure of ZC is 8°
less than the measure of ZD. Find the values of x and y.
Answer:
m<D=67
m<C=59
Step-by-step explanation:
m<C=y-8
m<D=y
m<A=54
put all the angles together and equal to 180
(y-8)+(y)+(54)=180
now solve the equation
67=y
(67)-8=59

Lincoln estimates the height of a tree. Lincoln's estimate has a 6% error.
The actual height of the tree is 17 feet. What could be Lincoln's estimate?
Choose all the correct answers.
A 11
B 15.98
C 18.02
D 16.94
E 23
Answer: B, C and D
Explained:
17 * .06 = 1.02
So 15.98 - 18.02 are all within Lincoln’s estimate and error rate.
B, C and D are all within the 6% error rate. So the answers are B, C and D.
