Answer:

2nd year the account earned 20% from $30,000 = $6,000

by adding the earnings of 2 years, she will be able to spend $5,000 + $6,000 = $11,000

Step-by-step explanation:

Mrs. Foust wants to know Aziza’s age. She knows that Aziza is the middle child. Her sister, Capri, is 4 years older than Aziza, and her sister, Portia, is 5 years younger than Aziza. The sum of their ages is 38. Let a represent Aziza’s age. Which statements are true about this scenario? Check all that apply.

Answers

Answer:

The expression that represents Capri’s age is a + 4.

The expression that represents Portia’s age is a – 5.

Step-by-step explanation:

The expression that represents Capri's age is a + 4.

The expression that represents Portia's age is a -5.

To write an equation for this scenario, Capri's age needs to be equal to Portia’s age

The equation used to represent this scenario is a + a + 5 + 2 - 4 = 38.

Solving this equation will give Aziza's age.

Aziza'a age = a

Portia age = a - 5

Capri's age = 4 + a

a + a - 5 + 4 + a = 38

What role does substitution play when determining whether or not a given value is a solution to an equation or an inequality?

Answers

Answer:

Help verify values

Step-by-step explanation:

I basically help prove that the value fits and verifies that equation or inequality. By substituting a value for the variable within the equation or inequality and then solving it as a regular expression it should correctly output the same value on the other side of the equation or make the inequality true. For example, using the following inequality...

3x + 2 > 4

We can substitute the variable x for 2 and solve the inequality, if the inequality is true then we know that the value 2 is a correct and verified value.

(3*2) + 2 > 4

6 + 2 > 4

8 > 4  ... True

Select all expressions that are squares of linear expressions. Group of answer choices x2+6x+36 (12x+4)2 (2d+8)(2d−8) p2−6p+9 x2+36 9x2−36

Answers

Answer:

(12x+4)² and p²−6p+9

Step-by-step explanation:

From the given choices, we areto select the one that are squares of linear expressions

1) For the expression (12x+4)²

This is regarded as the square of 12x+4 since the expression 12x4 is enclosed in parenthesis

2) For the expression p^2−6p+9

Factorize;

p^2−6p+9

p^2−3p-3p+9

p(p-3)-3(p-3)

(p-3)(p-3)

(p-3)²

Hence p^2−6p+9 is a square of the expression p-3

This are the only two required expressions (12x+4)² and p²−6p+9

Answers

Answer: $1.80

Step-by-step explanation:

600 grams - .6 kg

.6x+1.5y=4.62

y=x-1.4

.6x+1.5(x-1.4)=4.62

.6x+1.5x-2.1=4.62

3. Samantha is training to run a marathon. The first week she runs 4 km each day. The next week, she runs 7 km each day. During each successive week (each week following), each day she runs 3 km farther than she ran the days of the previous week. If she runs for five days each week, what total distance will Sara run in a 12-week training session?

Answers

1,230km


Week 1 = 5 x 4km = 20
Week 2 = 5 x 7km = 35
Week 3 = 5 x 10km = 50
Week 4 = 5 x 13km = 65
Week 5 = 5 x 16km = 80
Week 6 = 5 x 19km = 95
Week 7 = 5 x 22km = 110
Week 8 = 5 x 25km = 125
Week 9 = 5 x 28km = 140
Week 10 = 5 x 31km = 155
Week 11 = 5 x 34km = 170
Week 12 = 5 x 37km = 185

= 1230km

The total distance will Sara run in a 12-week training session is 1230 .

What is sum of terms in AP?

An arithmetic progression is a sequence of numbers or variables in which the difference between consecutive terms is the same. There can be an infinite number of terms in an AP.

The formula for finding the sum of first n terms of an AP given in the form of "a, a + d, a+2d, a+3d, ....., a+(n-1)d" is:

[tex]S _{n}[/tex]= [tex]\frac{n}{2}[/tex] [tex][2a + (n-1)d][/tex]

According to the question

Samantha is training to run a marathon.

She runs for five days each week

The first week she runs 4 km each day.  = 5 × 4 = 20

The second week, she runs 7 km each day. = 5 × 7 = 35

During each successive week , each day she runs 3 km farther than she ran the days of the previous week.

The third week, she runs 10 km each day. = 5 ×10 = 50

So on

Sara run in a 12-week training session

As this sequence is in AP  

First term (a) = 20

common difference (d) = 35 - 20

                                      = 15

Now,

Sum of 12 terms in AP

[tex]S _{n}[/tex]= [tex]\frac{n}{2}[/tex] × [2a + (n-1)d]

Substituting the values, a = 20, d = 15 and n = 12 in the above formula

[tex]S _{12}[/tex] = [tex]\frac{12}{2}[/tex] × [tex][2(20) + (12-1)15][/tex]

[tex]S _{12}[/tex] = [tex]6 [40 + (11)15}[/tex]

[tex]S _{12}[/tex] = [tex]6 [205][/tex]

[tex]S _{12}[/tex] = [tex]1,230[/tex]

Hence, the total distance will Sara run in a 12-week training session is 1230 .

Answers

Answer:

1.6 meters

Step-by-step explanation:

The distance between Shane and the bottom of the cliff is 7.8 meter while Naomi is standing 6.2 meters away from the bottom of the cliff.

As such, the distance between Shane and Naomi would be the difference between Shane's distance from the bottom of the cliff and Naomi's distance from the bottom of the cliff

= 7.8 - 6.2

= 1.6 meters

Tiana would like to buy cone-shaped hats for her birthday party. She wants hats with the largest volume, since they look bigger. Which of the following brands of hat should she buy?

Brand A:
height of cone = 15 in.
radius of cone base=6 in.

Brand B:
height of cone = 18 in.
radius of cone base=5 in.

A. Brand A
B. Brand B
C. Either - the hats have equal volumes

Answers

The formula for a volume of a cone is v= πr^2h/3.

Brand A: π6^2(15/3)

Brand A: volume is about 565.49

Brand B: π5^2(18/3)

Brand B: volume is about 471.24

Brand A holds more volume so A would be the correct answer to the question.

Brand A hat is more preferable with largest volume i.e. 565.2 cu. inches.

What is Cone?

A cone is a distinctive three-dimensional geometric figure that has a flat surface and a curved surface, pointed towards the top.

Here, Given data are:

Height of cone for Brand A = 15 in.

Radius of cone of Brand A =6 in.

Volume of Cone of brand A = [tex]\frac{1}{3}\pi r^2h[/tex]

               V =[tex]\frac{1}{3}X 3.14X6^2X15[/tex]

               V = 565.2 cu. in.

Height of cone for Brand B = 18 in.

Radius of cone of Brand B =5 in.

Volume of Cone of brand A = [tex]\frac{1}{3}\pi r^2h[/tex]

               V =[tex]\frac{1}{3}X 3.14X5^2X18[/tex]

               V = 471 cu. in.

Volume of brand A > volume of brand B.

Thus, Brand A hat is more preferable with largest volume i.e. 565.2 cu. inches.
