Answer:

Step-by-step explanation:

The number 2 1/4 is split into the sum 2 + 1/4, then multiplied by 3/8. This gives ...

  [tex]\displaystyle\frac{3}{8}\cdot2\frac{1}{4}=\left(\frac{3}{8}\cdot\boxed{2}\right)+\left(\frac{3}{8}\cdot\frac{1}{4}\right)\\\\=\frac{6}{8}+\frac{3}{\boxed{32}}=\frac{24}{32}+\frac{3}{32}=\frac{24+3}{32}\\\\=\frac{\boxed{27}}{32}[/tex]

Step-by-step explanation:

1 gram = 100 centigrams

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.

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:

2

Step-by-step explanation:

The location of point G  which partitions the directed line segment from D to F into a 5:4 ratio is; x = 3

The formula for coordinate of a point that divides a line segment in a ration is given by;

x = (mx₂ + nx₁)/(m + n)

We are given the ratio 5:4

Thus m = 5 and n = 4

The endpoints of DF are D(-2) and F(7)

Thus;

x = ((5*7) + 4(-2))/(5 + 4)

x = 27/9

x = 3

Thus, the location of point G  which partitions the directed line segment from D to F into a 5:4 ratio is x = 3

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)

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.

... Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction

_____

In the real world, it seems probable that Samantha will be offered the choice of using the coupon or the sale discount. If she chooses tht 50% coupon, her savings will be $30. If she chooses the marked sale discount, her savings will be $15.

The scenario above assumes she gets 50% off the sale price of $45, so saves $15+22.50 = $37.50 off the original price.

Answer:

The answer is B. (Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction.)

Answer:

  ∠C = 48°

Step-by-step explanation:

The two triangles are congruent by ASA. (The common side BD is between the angles marked congruent.) This means angles A and C have the same measure.

Angle A plus the two given angles will total 180°.

  ∠A = 180° -70° -62° = 48°

  ∠A = ∠C = 48°

Answer:

c=48°

Length of rectangles = 7 in.

Breadth of 4 rectangles = 3 x 4

                                          = 12 in.

Side of squares = 3 in.

Area of 4 rectangles = length x breadth

                                    = 7 x 12

                              = 84 sq. in.

Area of two squares = 2(side x side)

                                  = 2(3 x 3)

                                  = 18 sq. in.

Therefore, Surface area of the Jewellery box = 84 sq. in. + 18 sq. in.

                                                                              = 102 sq. in.

Answer:

Average grade now = 7.524

Step-by-step explanation:

Given - If the average score of the 20 students is 7.5. Then a student follows the test and gets a grade of 8.

To find - What is your average grade now?

Proof -

Given that,

Average score of 20 students = 7.5

So,

Total value of students = 20 × 7.5 = 150

Now,

Given that, One person added ang his grade is 8

So,

So Total value of 21 students = 150 + 8 = 158

Now,

Average score of 21 students = [tex]\frac{158}{21}[/tex] = 7.5238

∴ we get

Average grade now = 7.524
