y = -10÷-4

y = 2.5

Answer:

5^43

Step-by-step explanation:

[5² . 5² . 5³. 125 . 125³ ]³ : [25² . 5² . 5]² =

= [5² . 5² . 5³. 5³ . (5³)³ ]³ : [(5²)² . 5² . 5]²

= [5² . 5² . 5³. 5³ . 5^9 ]³ : [5^4 . 5² . 5]²

= [5^19]³ : [5^7]²

= 5^57 : 5^14

= 5^43

-6y-12<12-4y

First, add 12 on both sides.

-6y<24-4y

Now add 4y on both sides.

-10y<24

Divide -10.

y<-2.4

hope it helps

Q Nine divided by the product of a number and Five

Let the number = x

product of a number and Five = x * 5 = 5x

The expression is given as;

[tex]\frac{9}{5x}[/tex]

Q2 The product of a sum and difference of x and y​

Sum of x and y = x + y

Difference of x and y = x - y

The expression is given as;

(x + y) * ( x -y)

x^2 + xy - xy - y^2

x^2   - y^2

Answer:

Number of students who got grade A = [tex]\frac{8y}{x}[/tex]

Step-by-step explanation:

Number of students who got grade B = 8

Ratio of the students that got A to the students who got B = [tex]y:x[/tex]

That is

Number of students who got grade A : Number of students who got grade B =  

[tex]y:x[/tex]

Number of students who got grade A : 8 = [tex]y:x[/tex]

Therefore,

Number of students who got grade A = [tex]\frac{8y}{x}[/tex]

Answer: 14

Step-by-step explanation:

Given

Excavation cone measures

height [tex]h=6\ ft[/tex]

Diameter [tex]d=30\ ft[/tex]

Truck can dump [tex]125\ ft^3[/tex] at a time

The volume of a cone is

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Putting values

[tex]\Rightarrow V=\dfrac{1}{3}\times \pi\times 15^2\times 6\\\Rightarrow V=1413.9\approx 1414\ ft^3[/tex]

No of trips(N) required to accumulate this much volume is given by

[tex]\Rightarrow N=\dfrac{1414}{125}=13.3\approx 14[/tex]

Therefore, 14 trips are necessary to accumulate a cone of volume [tex]1414\ ft^3[/tex]

Answer:

Answer:

1. 40 ft

2. 150 bricks

3. 100 ft

Step-by-step explanation:

Answer:

1st place on perimeter is 40

last on perimeter is 100

2nd place on # of bricks is 150

Step-by-step explanation:

200 bricks is 80 square feet, so 200/80 is 2.5. so 2.5 bricks is one square foot, that means that 25 bricks is 10 square feet, 20 is 50, and so on

Answer:

Answer:

Members that voted yes = 15 Members

Step-by-step explanation:

Members that voted yes : members that voted no = 5 : 1

Total ratio = 5 + 1 = 6

total school board members that voted = 18

how many voted yes for new math books?

Members that voted yes = 5/6 × 18

= 0.8333333333333 × 18

= 15 members

Members that voted yes = 15 Members

members that voted no = 1/6 × 18

= 0.1666666666666 × 18

= 3

members that voted no = 3 members

Answer:

120.

Step-by-step explanation:

area = L x W which means you multiply 15x 8.

Answer:

The amount of each ingredient Alicia uses to make oat biscuits are;

440 g of oat, 220 g of butter, and 110 g of syrup

Step-by-step explanation:

9. The question parameters are

The ingredients with which Alicia makes oat biscuit = Syrup, butter, and oat

The ratio of the ingredients with which Alicia makes oat biscuit = 1 : 2 : 4

The quantity of syrup Alicia has = Large amount (Plenty)

The amount of butter she has = 250 g

The amount of oat she has = 440 g

From the given ratio, we have;

The mass of oat Alicia uses is 2 times the mass of butter she uses and 4 times the mass of syrup she uses

When Alicia uses the 440 g of oat, we have;

The amount of butter she will use = 440 g/2 = 220 g

The amount of syrup she will use = 440 g/4 = 110 g

Therefore, Alicia uses the 440 g of oat, 220 g of butter, and 110 g of syrup

Answer:

  125°

Step-by-step explanation:

Let x represent the angle in degrees. Its supplement is (180-x) degrees. The given relation is ...

  x = 15 +2(180-x)

  x = 375 -2x . . . . simplify

  3x = 375 . . . . . . add 2x

  x = 125 . . . . . . . divide by 3

The measure of the angle is 125°.

Answer:

D). The distribution of the data is symmetrical, so the mean and median are within the "2.1-3 mile" category.

Step-by-step explanation:

The last statement i.e. 'The distribution..."2.1-3 mile" category' correctly asserts a true claim regarding the data provided in the given histogram. It aptly states that the dissemination of the data is uniform(2, 4, 5, 4, 2(no. of students) live between the distance of 0.1 to 5 miles from the school) and this causes both the mean, as well as, the median of the distribution to fall in the category between '2.1 to 3 mile.' Thus, option D is the correct answer.

Answer:

$6000

Step-by-step explanation:

Given data

Principal=$10000

Rate=4%

time=15years

The simple interest id found by

SI=PRT/100

substitute

SI=10000*4*15/100

SI= 600000/100

SI=$6000

Hence the interest is $6000

20 out of 100 read 5 or more.

20/100 = 0.2

Now multiply the total students by 0..2:

275 x 0.2 = 55

55 people read 5 or more books.

Answer:

Angle ABC: 110°

Angle XYZ: 75°

Answer:

Abc is 110

xyz is 75

Step-by-step explanation:

If you look at abc it is a obtuse (more than 90) and 110 is the only one over 90

xyz is a acute angle meaning less than 90. there are 2 possible answers but it is so close to being 90 degrees that i have to say its 75
