A police officer paid 10% of her income between 0 and 8,350: 0.10*8350=$835
A police officer paid 15% of her income between 8350 and 33,950: 33,950-8,350=25,600⇒0.15*25,600=$3,840
A police officer paid 25% of her income between 33,950 and 47,050: 47,050-33,950=13,100⇒0.25*13,100=$3,275

$835+$3,840+$3,275=$7,950

The policy officer paid $7,950 in federal income tax.

Pam spelled 68 of 100 words correctly on the pretest. How many words did she miss? If she learns 8 of those each day, how long w

Fofino [41]

Answer:

Pam missed 32 words in her pretest.

It will take 4 days for Pam to learn all missed words.

Step-by-step explanation:

Given:

Number of words spelled correctly = 68

Total number of words on the pretest = 100

We need to find the number of words she missed.

Solution:

now we can say that;

Number of words she missed can be calculated by subtracting Number of words spelled correctly from Total number of words on the pretest.

framing in equation form we get;

Number of words she missed = $100 -68 =32\ words$

Hence Pam missed 32 words in her pretest.

Now Given:

Number of words missed learned each day = 8

Total number of words missed = 32 words.

We need to find how long will take to learn them all.

now we can say that;

days required to learn missed words is equal to total number of words missed divided by Number of words missed learned each day.

framing in equation form we get;

Days required to learn missed words = $\frac{32}{8}=4\ days$

Hence It will take 4 days for Pam to learn all missed words.

8^(3x-1)=2^8 Solve for x

Yuri [45]

$8^{(3x-1)}=2^8 \\\\ 2^{3(3x-1)}=2^8 \\\\ 3(3x-1)=8 \\\\ 9x-3=8 \\\\ 9x=8+3 \\\\ 9x=11 \\\\ \boxed{x=\frac{11}{9}}$

Anika is hiking on a rectengular trail at the nation park there are four resting spots along the corners of the trail on the map

Drupady [299]

Answer:

The perimeter is 14 units

Step-by-step explanation:

Given

$A = (-2,2)$

$B = (1,2)$

$C = (1,-2)$

$D = (-2,-2)$

Required

Determine the perimeter

To do this, we simply calculate the distance between the sides of the rectangle i.e. AB, BC, CD and DA.

Distance (d) is calculated using:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

For AB

$A = (-2,2)$ --- $(x_1,y_1)$

$B = (1,2)$ --- $(x_2,y_2)$

$AB = \sqrt{(-2 - 1)^2 + (2 - 2)^2} = \sqrt{9} = 3$

For BC

$B = (1,2)$ --- $(x_1,y_1)$

$C = (1,-2)$ --- $(x_2,y_2)$

$BC = \sqrt{(1-1)^2 + (2--2)^2} = \sqrt{16} = 4$

For CD

$C = (1,-2)$ --- $(x_1,y_1)$

$D = (-2,-2)$ --- $(x_2,y_2)$

$CD = \sqrt{(1 - -2)^2 + (-2 -- 2)^2} = \sqrt{9} = 3$

For DA

$D = (-2,-2)$ --- $(x_1,y_1)$

$A = (-2,2)$ --- $(x_2,y_2)$

$DA = \sqrt{(-2--2)^2 + (-2-2)^2} = \sqrt{16} = 4$

So, the perimeter (P) is:

$P = AB + BC + CD + DA$

$P = 3 +4 + 3 + 4$

$P = 14$

The perimeter is 14 units
