Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ - 55}}}}}[/tex]

Step-by-step explanation:

Given, a = -6 , b = -5

[tex] \sf{5a + 5b}[/tex]

plug the value of a and b

⇒[tex] \sf{5 \times ( - 6) + 5 \times ( -5)}[/tex]

Multiply the numbers

⇒[tex] \sf{ - 30 + ( - 25)}[/tex]

We know that , [tex] \sf{( + ) \times ( - ) = ( - )}[/tex]

Answer:

FV= $95,454.20

Step-by-step explanation:

Giving the following information:

Annual deposit= $2,000

Number of periods= 25 years

Interest rate= 5% compounded annually

To calculate the future value of the annual deposits, we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

FV= {2,000*[(1.05^25) - 1]} / 0.05

FV= $95,454.20

Step-by-step explanation:

False: equilateral triangle has 3 equal sides and 3 equal angles measure 60 degrees

Answer:

True

Step-by-step explanation:

In an equilateral triangle, all sides are equal in length.

That means that all the angles of the triangle will be congruent.

Since a triangle has 3 angles that always add up to 180 degrees, each angle is 60 degrees.

(180/3=60)

A right triangle must have one 90 degree angle.

An obtuse triangle must have an angle that is greater than 90 degrees.

An acute triangle's angles must all measure 89 degrees or less.

Hence, the given statement is true.

Equilateral triangles can be classified as acute.

Step-by-step explanation:

given data:

total beans = 9

blue beans = 6

red beans = 1

yellow beans = 1

green beans = 1

solution:

This is a permutation problem because there is a condition attached to it which states that the beans most be arranged in a way that atleast each none blue has a blue bean on its side when shared.

= ( r + n - 1 ! ) / r ! ( n - 1 )!

= 3 + 6 - 1 / 3! ( 6-1 )!

= 8! / 3! x 5!

= 40320/ 720

Complete question is;

Identify the type of sampling​ used: random,​ systematic, convenience,​ stratified, or cluster.

To estimate the percentage of defects in a recent manufacturing batch, a quality control manager at General Foods selects every 18th soup can that comes off the assembly line starting with the fifth until she obtains a sample of 40 soup cans

Answer:

Systematic Sample

Step-by-step explanation:

We are told that the quality control manager selects every 18th soup can that comes off the assembly line starting with the fifth until she obtains a sample of 40 soup cans.

Thus, the selection is from a large sample of produce.

This is synonymous with systematic sample because systematic sample can be defined as a type of probability sampling in which sample members from a larger population are selected according to a random starting point but with a set periodic interval.

This resonates with the statement in the question about selecting every 18th soup from the production assembly line.

Let roses be R and carnations be C

"in a ratio of 2 to 7" means that the ratio of R to C is 2 to 7, meaning you'll have to cross multiply to translate it algebraically

[tex]R:C\\2:7\\7R=2C\\[/tex]

since C = 343 we plug 343 in [tex]7R=2C[/tex]:

[tex]7R=2(343)\\7R=686\\R=\frac{686}{7} \\R=98[/tex]

ergo, she needs 98 roses

to make sure of the answer:

"ratio of 2 to 7" is technically a fraction =>  [tex]\frac{2}{7}[/tex]

and since the ratio of the roses to the carnations is the same as [tex]\frac{2}{7}[/tex] we plug the values R = 98 and C=343:

[tex]\frac{R}{C}=\frac{98}{343}=\frac{2}{7}[/tex]

Answer:

61.8 miles/hr

Step-by-step explanation:

Given that

Dennis starts from Boston and travels to Hartford for 101 miles.

And then he travels towards Baltimore which is 410 miles away from Boston.

Time taken from Hartford to Baltimore = 5 hours

Kindly refer to the image attached for the trip of Dennis and the distance traveled by him.

Point A represents Boston.

Point B represents Hartford.

Point C represents Baltimore.

Distance AB = 101 miles

Distance AC = 410 miles

Actually, we are given that Distance BC is traveled in 5 hours.

Distance BC = AC - AB = 410 - 101 = 309 miles

Average Speed is given as:

[tex]\text{Average Speed = }\dfrac{\text{Total Distance traveled}}{\text{Total Time Taken}}[/tex]

So,

[tex]\text{Average Speed = }\dfrac{309}{5}\\\Rightarrow \text{Average Speed = }\bold{61.8\ miles/hr}[/tex]

Tara have a total of 370 m² lawn left to mow

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The total area of the lawn = 925 m²

Before talking to neighbor

Tara mows ( 3/5 ) of total area of the lawn

So ,

The area left for her to mow is = 1 - 3/5

                                                   = 2/5

So , the equation will be

The area for Tara to mow = 2/5 x total area of the lawn

                                           = 2/5 x 925

                                           = 2 x 185

                                           = 370 m²

Hence , Tara have a total of 370 m² lawn left to mow

Answer:

$3,000

Step-by-step explanation:

To find his average monthly pay, you have to find the total amount that Willian received in a year by multiplying his monthly salary as a teacher for 10 months and his salary as a barista for 2 months and adding up these numbers. Then, you have to divide the total amount he earned by 12 that is the number of months in a year:

($3,200*10)+($2,000*2)= $32,000+4,000=36,000

$36,000/12=$3,000

According to this, his average monthly pay for the 12 months was $3,000.

We are given the equation:

√10(128 + 2)

We can simplify what is in parenthesis.

√10(130)

We can put the number in parenthesis on the left side of the square root.

130√10

As a decimal, it would equal approximately 411.10

Answer:

6 with a reminder of 2 :)

4 is the quotient and 2 is the remainder when 26 divided by 4.

A division is a process of splitting a specific amount into equal parts.

The number which we divide is called the dividend.

The number by which we divide is called the divisor.

The result obtained is called the quotient.

The number left over is called the remainder.

26 divided by 4

26 is the dividend

4 is the divisor

26/4

26 we can split as 24+2

24 is divided by 6 which results 4 and 2 is the remainder. So 4 is the quotient and 2 is the remainder

Hence, 4 is the quotient and 2 is the remainder when 26 divided by 4.
