In order to achieve his goal of paying the credit debt off in 24 months, B. Gio can eliminate $62.57 from Entertainment/Shopping.

If Gio is paying $105, the number of months that he will be able to pay back the debt in, can be found using credit card debt calculators to be 3 years and 10 months.

In order to pay back his credit card debt in 24 months, the minimum amount he needs to pay is:

= $167.57 per month

Considering that he is currently paying $105, the amount extra that he needs to pay is:
= 167.57 - 105

= $62.57

This can be acquired from Entertainment/ Shopping.

In conclusion, option B is correct.

Answer:

Grace is correct. She needs 24 cups of lemonade.

Step-by-step explanation:

With the current ratio 4:3, if you were to have 24 cups of lemonade, then you would have 18 cups of sparkling juice. 24 + 18 = 42 total cups of punch.

Answer:

2:26.

Step-by-step explanation:

There are 26 blocks total, and compared to the yellow blocks, there are only two. So that would be 2:26.

Answer:

2:26

Step-by-step explanation:

A ratio is just a mathematical way to show a relationship between things. I wrote it with a colon (:), but you can write it as a fraction or words "x to b."

Most of the time in math, the order of how the question is asked doesn't matter. When it's a ratio, it does matter. Because they ask about the yellow blocks first, that has to be the first part of the ratio.

There are 2 yellow blocks.

Next, it asks for the total. That will be the other part. Add all the total blocks together: 5+7+2+12= 26.

There are 26 total blocks.

Technically, we can simplify this down to 1:13, but it's not asking to simplify it, so let's just leave it as 2:26.

The value of (x-1)^2 at scores 1,2,1, and 4 are 0,1,0,8 respectively.

Quadratic equations are the polynomial equations of degree 2 in one variable of type  [tex]ax^2+bx+c[/tex] where a,b,c are constant and the x is variable.

Now from the given question we have  [tex](x-1)^2[/tex].

[tex](x-1)^2=x^2-2x+1[/tex]

Now we will find the value of scores 1,2,1,4 by putting in the equation.

At

[tex]x=1 \ \ \ =(1-1)^2=0\\\\\\x=2\ \ \ =(2-1)^2=1\\\\\\x=1\ \ \ =(1-1)^2=0\\\\\\x=4\ \ \ =(4-1)^2=8[/tex]

Hence the value of (x-1)^2 at scores 1,2,1, and 4 are 0,1,0,8 respectively.

Notice that the dividend [tex]8y^2-12y+4[/tex] has tree terms with [tex]a=8y^2[/tex], [tex]b=-12y[/tex], c [tex]c=4[/tex]

Now, to divided our dividend [tex]8y^2-12y+4[/tex] by the monomial (single term) [tex]4y[/tex], the easiest thing to do is divide each term of the dividend by the monomial:

[tex]8y^2-12y+4[/tex] ÷ [tex]4y[/tex] = [tex]\frac{8y^2-12y+4}{4y}=\frac{8y^2}{4y}-\frac{12y}{4y}+\frac{4}{4y}=2y-3+\frac{1}{y}[/tex]

After performing the division we get that now [tex]a=2y[/tex] and [tex]b=-3[/tex]

Answer:

A) 75°

Step-by-step explanation:

It is the property of a polygon that the sum of the external angles is equal to 360°.

===============================================================

Solving :

⇒ p + 55 + 30 + 75 + 55 + 70 = 360

⇒ p + 85 + 130 + 70 = 360

⇒ p + 285 = 360

⇒ p = 360 - 285

⇒ ∠p = 75°

Answer :

A) 75°

because the property of polygon is equal to 360° the sum of external angles.

Answer:

2 codes are possible

Step-by-step explanation:

4 6  

2571

0389

There are only 10 digits and you can only use the digits onces so the answer would be 2 codes are possible.

The number of possible codes will be 5,040.

If each digit can be used only once, then the number of possible access codes is calculated as follows:

The first digit can be any of the 10 digits (0 through 9).

The second digit can be any of the remaining 9 digits (since one digit has already been used).

The third digit can be any of the remaining 8 digits.

The fourth digit can be any of the remaining 7 digits.

Therefore, the total number of possible access codes is:

10 x 9 x 8 x 7 = 5,040

So, there are 5,040 possible access codes if each digit can be used only once and not repeated.

Since there are 200 employees, the company has enough unique codes for each employee for 25 months. After that, the codes will have to be repeated, which may compromise the security of the system.

Answer:

$1555.91

Step-by-step explanation:

First Month:

You start out with $500.

You add $200 in the first month, and have 700.

Multiply 700 by 1.01, to add the interest and you get 707.

Second Month:

707 + 200 = 907

907 x 1.01 = 916.07

Third Month:

916.07 + 200 = 1116.07

1116.07 x 1.01 = 1127.2307

Fourth Month:
1127.2307 + 200 = 1327.2307

1327.2307 x 1.01 = 1340.503007 (round to .50)

Fifth Month:

1340.50 + 200 = 1540.50

1540.50 x 1.01 = 1555.905

Round to 1555.905 1555.91, and there's your answer. Hope this helps!

Answer:

5.32 inches

Step-by-step explanation:

It is given that 1 inch represents 50 feet, or 1 in = 50 feet.

The actual dome is 266 feet. To find the amount of inches, divide 266 with 50:

266 total feet/50 feet per inch = 5.32 inches.

The scale model in inches, therefore, would be 5.32 inches.

√x^2= √449

x= 21.19ft

Thus, the length of the ladder is 21.19feet.
