Answer 1

Answer: a) (3,0.5) b)(28/13, 47/13)

1)7x+4y=23

8x-10y=19

70x+40y=230

32x-40y=76

102x=306

x=306/102=3

7(3)+4y=23

21+4y=23

4y=2

y=1/2

2)Step-by-step explanation:

11x-6y=2

-8x+5y=3

Multiply the first equation by 5 and the second by 6.

55x-30y=10

-42x+30y=18

Now add both of the new equations

13x=28

x=28/13

Now plug it into the first equation to find y

11(28/13)-6y=2

308/13-6y=2

y=47/13

A) 23. 5


B) 94


C) 266


D) 133

Answers

Answer:

D 133 degrees

Step-by-step explanation:

The measure of an angle external to a circle = the difference of the two arcs intercepted divided by 2

47  = [ (360 - x) - x ] / 2

94 = 360 - 2x

x = 133 degrees of the arc

Christina also plans on leaving her $10,000 invested for 20 years. Write an equation representing her investment’s value, y, after x years. What is the value of Christina’s investment after 20 years?

Answers

The required equation is y = 10000(1.0.25)^2x. The value of Christina’s investment after 20 years is $30,773.14

Compound interest

The interest accrued on a sum of money is known as interest. The formula for calculating the compound interest is expressed as:

y = y0(1+r/n)^nx

where

x is the time taken

r is the rate in decimal

n is the compounding time


Given the following

x = 20 years

n  2(semi annually)

r  = 5.7% = 0.057

Substitute

y = 10000(1+0.057/2)^2(20)
y = 10,000(1 + 0.0285)^40

y = 10000(1.0285)^40
y = 30,773.14

Hence the value of Christina’s investment after 20 years is $30,773.14

In how many distinguishable ways can the letters of the word ILLINOIS

Answers

Answer:

3360 ways

Step-by-step explanation:

ABCDEFGH-- there are 8! ways to organize these letters

[tex]\frac{8!}{2!3!}[/tex]=3360

Step-by-step explanation:

Since the two L’s must be consecutive, we consider them to be a single letter LL. Then the word ILLINOIS has n = 7 letters: 3 I’s, 1 LL, 1 N, 1 O and 1 S. Hence the numbers of ways to permute letters of the word ILLINOIS if the two L’s must be consecutive is: 7!

A triangle has side lengths measuring 2x 2 ft, x 3 ft, and n ft. which expression represents the possible values of n, in feet? express your answer in simplest terms. x – 1 < n < 3x 5 n = 3x 5 n = x – 1 3x 5 < n < x – 1

Answers

The expression x – 1 < n < 3x + 5 represents the possible values of n, in feet whose side lengths are (2x+2) ft, (x+3) ft, and n ft.

What is the triangle?

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle whose side lengths measures are (2x+2) ft, (x+3) ft, and n ft.

If we take the first two sides are (2x+2) ft, (x+3) ft, and third is n ft.

By the triangle property, that sum of the two sides is always greater than the third side.

2x+2+x+3 > n

3x+5 > n  .....(1)

Now take first two sides as n ft, (x+3) ft, and third side (2x+2) ft

n+x+3 > 2x+2

n > x-1 .....(2)

From the inequality (1) and (2), we get:

x – 1 < n < 3x + 5

Thus, the expression x – 1 < n < 3x + 5 represents the possible values of n, in feet whose side lengths are (2x+2) ft, (x+3) ft, and n ft.

If the price of the cake is $45 and each balloon costs $15.
how many balloons can she buy?


Need the inequality and equality answer, and final answer

Answers

Answer:

The answer is 3

Step-by-step explanation:

You have to subtract 120-45 and that gets you to 75 Then divide 75 by 15 and that gives you 3. So the answer is 3

Answer:

15n + 45 ≤ 120

n ≤ 5

She can buy up to 5 balloons.

Step-by-step explanation:

Fixed amount: $45

Amount per balloon: $15

Let n = number of balloons

Total expense: maximum of $120, which means less than or wequal to $120

15n + 45 ≤ 120

15n ≤ 75

n ≤ 5

She can buy up to 5 balloons.

The area of a gymnasium is 956 yd2. The width of the gymnasium is 4 yd longer than its length. Find the length and width of the gymnasium (round to the nearest yard). Include a labeled diagram in your work for full credit?

Answers

Answer:

L = 29

w = 33

Step-by-step explanation:

  Area = w × L

           = (L + 4) × L

⇔ 956 = L² + 4L

⇔ 956 = (L + 2)² − 4

⇔ 956 + 4 = (L + 2)²

⇔ 960 = (L + 2)²

[tex]\Leftrightarrow L+2=\sqrt{960}[/tex]

[tex]\Leftrightarrow L+2=30.983866769659[/tex]

[tex]\Longrightarrow L+2 \approx 31[/tex]

Grayson was given a large box of 42 chocolates for his birthday. If he eats exactly 2 chocolates each day, how many chocolates would Grayson have remaining 15 days after his birthday?

Answers

Answer:

12

Step-by-step explanation:

Let's write this in ratio form.

Days : Chocolates

1 : 2

15 : 30

So, he would eat 30 chocolates in 15 days. To find the remaining ones, we will subtract from the total of the chocolates given.

Chocolates = 42 - 30

Samantha is trying to pick out an outfit for the first day of school. She can choose from 2 pairs of pants, 2 t-shirts, and 9 pairs of shoes. How many different outfits does Samantha have to choose from?

Using the Fundamental Counting Theorem, it is found that Samantha has 36 different outfits to choose from.

What is the Fundamental Counting Theorem?

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

In this problem:

For the pants, there are 2 options, hence [tex]n_1 = 2[/tex].For the t-shirts, there are 2 outcomes, hence [tex]n_2 = 2[/tex].For the shoes, there are 9 outcomes, hence [tex]n_3 = 9[/tex].

Answers

For a $1000 face value purchased at a discount price of $925, if it pays 6% fixed interest for the duration of the bond is the yield on a corporate bond mathematically given as

Yield = 6.5%

What is the yield on a corporate bond?

Generally, the equation for the interest paid is mathematically given as

Interest paid = value of bond x Interest rate

Interest paid = 1000 * 6%

Interest paid = 60

Therefore

Yield = Interest paid / Price paid

Yield = (60 / 925)x 100

Yield = 6.5%
