Answer:

-2m

Step-by-step explanation:

-6m + 4m

Combine like terms by performing the operation between the coefficients. In this case, one must add the different coefficients, yet since one of the coefficients is negative, then adding the two coefficients is the same as subtracting the two terms.

-6m + 4m

= -2m

Answer:

62.5 %

Step-by-step explanation:

The percentage, p of the ice cream that is chocolate is p = total number of chocolate ice cream cups/total number of ice cream cups × 100%

Given that there are 25 chocolate ice cream cups and 15 vanilla ice cream cups, total number of ice cream cups  = 25 + 15 = 40

So, p = total number of chocolate ice cream cups/total number of ice cream cups × 100%

p = 25/40 × 100%

p = 25/4 × 10 %

p = 6.25 × 10 %

p = 62.5 %

Answer:

B.

Step-by-step explanation:

Surface area = πr(r + L)   where r = radius of the base and L = the slant height.

= 12π(12 + 40)

= 12*52π

= 624π.

Answer:

Step-by-step explanation:

3/5 = 0.6

1 - 0.6 = 0.4 students left

Multiply the amount of students remaining by the fractional amount that take German

0.4  x  1/4   =   0.1

1 - 0.6 - 0.1 = 0.3

0.3 x 100 = 30%

Therefore 30% of students take French

if it's $4 per ride, we can divide the remaining money ($28) by the cost of each ride ($4)

28 / 4 = 7

Therefore, she can ride 7 rides

The momentum of a variable is represented by the rate of change. The rate of change for the situation is 3 miles per hour.

The momentum of a variable is represented by the rate of change, which is used to quantitatively express the percentage change in value over a specific period of time.

Given the distance covered in one hour is 3 miles, while the distance covered in 2 hours is 6 miles. In the given case, the rate of change for the situation, therefore,

Rate of change = (6miles-3miles)/(2hours-1hour) = 3miles/hour.

Hence, the rate of change for the situation is 3 miles per hour.

Answer:

  a) $2.40

  b) $16.80

  c) y = -2.40x +16.80

Step-by-step explanation:

a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4

Dylan spends $2.40 at lunch every day.

__

b. The y-intercept can be found from the formula ...

  b = y1 -m(x1)

  b = 12 -(-2.40)(2) = 16.80

Dylan's dad gives him $16.80 at the beginning of each week.

__

c. The slope-intercept equation is ...

  y = mx + b

  y = -2.40x +16.80

Answer:

FV= $10,714.81

Step-by-step explanation:

Giving the following information:

Initial investment= $7,567

Number of periods= 7*4 = 28 quarters

Interest rate= 0.05/4= 0.0125

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

FV= PV*(1+i)^n

FV= 7,567*(1.0125^28)

FV= $10,714.81

The value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.

A binomial expression is an expression that has two terms.

In order to get the value of t for which the given expression 2x²+tx+10 will be a product of two binomial. We need to find a number(A) that is when broken into two other numbers(B and C), the sum of these numbers(B and C) is the number itself(A). Also, the product of the two numbers is equal to the product of the rest two terms of the expression(2 and 10).

Therefore, the number that fulfills this condition is 9. Let's check by substituting the value of t as 9.

[tex]2x^2+tx+10\\\\= 2x^2+9x+10 \\\\= 2x^2+5x+4x+10\\\\ = x(2x + 5)+2(2x+5)\\\\= (x+2)(2x+5)[/tex]

Hence, the value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.

[tex]Q = 29.3^\circ[/tex]

Step-by-step explanation:

Given

[tex]\angle S = 90[/tex]

[tex]RS = 2.2ft[/tex]

[tex]QR = 4.5ft[/tex]

See attachment for ΔQRS

To calculate <Q, we make use of:

[tex]sin\ Q = \frac{Opposite}{Hypotenuse}[/tex]

Where

[tex]Opposite = RS[/tex]

[tex]Hypotenuse = QR[/tex]

[tex]sin\ Q = \frac{RS}{QR}[/tex]

[tex]sin\ Q = \frac{2.2}{4.5}[/tex]

[tex]sin\ Q = 0.4889[/tex]

Take arc sin of both side

[tex]Q = sin^{-1}(0.4889)[/tex]

[tex]Q = 29.3^\circ[/tex]
