Answer:

a) Neither arithmetic nor Geometric

Explanation:

Since 99-89.9= 9.1, and 89.9 - 78.8 = 11.1, the sequence is not arithmetic.

Like wise 89.9/99=0.908 and 78.8/89.9 = 0.876 makes it not a geomtric sequence

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

99, 89.9, 78.8, 68.7, . . . . .

Here,

$a_1=99\\\\a_2=89.9\\\\a_3=78.8\\\\a_4=68.7$

But we can see that there is minor difference between the consecutive terms:

So, we will go for common difference whether it is same or not.

$a_2-a_1=89.9-99=-9.1\\\\a_3=a_2=78.8-89.9=-11.1\\\\a_4-a_5=68.7-78.8=-10.1$

Their difference are not common.

So, It is neither geometric nor arithmetic.

Hence, Option 'a' is correct.

Susan was supposed to use 5/4 of a cup of butter

ElenaW [278]

Answer:

$a.\ \dfrac{3}{5}$

Step-by-step explanation:

We can see the fractions $\frac{5}{4}$ and $\frac{3}{4}$ of cups.

It can be seen that denominator has 4 i.e. the fraction $\frac{1}{4}$ .

Let us suppose, a unit is equal to $\frac{1}4$ of a cup.

Susan was supposed to use $\frac{5}{4}$ of a cup.

i.e. 5 units of butter was to be used.

But, actual recipe has only 3 units of butter.

$\text{Fraction of butter used} = \dfrac{\text{Units of butter used}}{\text{Unit of butter Susan was supposed to use}}$

a. $\text{Fraction of butter used} = \dfrac{3}{5}$

Alternatively, we could have directly divided the given fractions:

$\dfrac{\dfrac{3}{4}}{\dfrac{5}{4}} = \dfrac{3}{5}$

The sum of two numbers is 15. The difference of he same two numbers is 3. What are the two numbers?

Angelina_Jolie [31]

x+y =15

x-y = 3

add the two equations

2x = 18

divide by 2

x = 9

x + y = 15

9 + y =15

subtract 9

y = 9

The two numbers are 6 and 9

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

Nikitich [7]

Answer:

Last week her sales were $4500.

Step-by-step explanation:

Given:

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works.

She also earns a base salary of $750 per week.

Her total earnings for the week were $1,076.25.

Now, to find her sales last week.

Let the sales of last week be $x.$

Base salary = $750.

Total earnings = $1076.25.

So, we deduct the base salary from the total earnings first:

$1076.25-750$

$=326.25.$

Thus, the rest of the earnings is $326.25 which is the 7.25% commission on sales.

Now, to get the sales of last week we put an equation:

$7.25\%\ of\ x=326.25$

$\frac{7.25}{100} \times x=326.25$

$\frac{7.25x}{100} =326.25$

Multiplying both sides by 100 we get:

$7.25x=32625$

Dividing both sides by 7.25 we get:

$x=4500.$

The sales of last week = $4500.

Therefore, last week her sales were $4500.

Calculate the total cost of the order: Veggiburger with cola and soup, sales tax 4%, tip 15.

djyliett [7]

Add the prices of the food together to get $7. Then you calculate the sales tax, which is 1.04 * $7 = $7.28. The tip is 15% I am assuming, and not 15, so it would be $7 * 0.15 = $1.05. Add $1.05 with $7.28 to get $8.33, so the answer is A.
