The sum of two numbers is 96 the larger number is nine less than four times the smaller number find both numbers

Answers

Answer:

21 and 96

Step-by-step explanation:

Let x and y be the two numbers such that x>y.

As the sum of both the numbers is 96.

x+y=96...(i)

As the larger number is nine less than four times the smaller number,

So, x=4y-9

From equation (i),

4y-9+y=96

5y=96+9=105

So, y=105/5=21

By using equation (i),

x=96-y=96-21=75

Hence, both the numbers are 21 and 96.

Answers

Answer:

210 boys

Step-by-step explanation:

the ratio is 7 boys to 5 girls. There are 150 girls at the school. Divide 150 by 5 to get your answer which is 30. We know that we have to divide because the ratio answer is a simplified version of 150, like if we were doing fractions. Then multiply 30 times 7 and you will get 210. So there are 210 boys at the school.

Step-by-step explanation:

A negative value of 'a' makes the parabola open downward, so the rightmost graph goes with a=-1.

A value of 'a' less than 1 flattens the graph, so the middle graph goes with a=0.25.

A value of 1 gives a standard open-upward parabola, corresponding to the leftmost graph.

Answer:

297 cm^2

Step-by-step explanation:

297 centimeters squared

The requried area of the shaded sector is 296.73 cm², which is closest to option D: 297 cm².

What is an area of a sector of a circle?

The area of a sector is the fractional part of the area of a full circle that is enclosed by the central angle of the sector. To find the area of a sector, we can use the formula:

Area of sector = (θ/360) x πr^2

Here,
To find the area of the shaded sector, we need to first find the area of the whole circle and then multiply it by the fraction of the circle that is shaded.

The area of a circle with a radius of 18 cm is given by A = πr², where r is the radius. So, the area of the whole circle is:

A = πr² = π(18 cm)² = 324π cm²

To find the fraction of the circle that is shaded, we need to find the central angle of the sector. The central angle of the sector is given as 105°. The fraction of the circle that is shaded is equal to the central angle of the sector divided by the total central angle of the circle (which is 360°):

Fraction of circle shaded = Central angle of sector / Total central angle of a circle

= 105° / 360°

= 7/24

Therefore, the area of the shaded sector is:

Area of shaded sector = Fraction of circle shaded x Area of the whole circle

= (7/24) x (324π cm²)

≈ 296.73 cm²

So, the approximate area of the shaded sector is 296.73 cm², which is closest to option D: 297 cm².

Colton works at an electronics store as a salesperson. Colton earns a 7% commission on the total dollar amount of all phone sales he makes, and earns a 3% commission on all computer sales. Colton had twice as much in phone sales as he had in computer sales and earned a total of $85 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Colton made and the dollar amount of computer sales he made. Define the variables that you use to write the system.

Answers

The equations that could be used to determine the dollar amount of phone sales will be:

0.07x + 0.03y = 85

y = 2x

How to illustrate the information?

Let x represent the total dollar amount of the phone sales she makes.

Let y represent the total dollar amount of the computer sales she makes.

Colton earns a 10% commission on the total dollar amount of all phone sales she makes, and earns a 4% commission on all computer sales. If she earned a total of $162 in commission, it means that

0.07x + 0.03y = 85

She had twice as much in computer sales as she had in phone sales. This means that y = 2x.

Answers

The co-ordinates of D is if the midpoint E is at (-1,0 )which is calculated using the section formula.

In coordinate geometry, the Section formula is used to determine the internal or external ratio at which a line segment is divided by a point. It is used to determine a triangle's centroid, incenter, and excentre.

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

The section formula is given by:

[tex]{\displaystyle P=\left({\frac {mx_{2}+nx_{1}}{m+n}},{\frac {my_{2}+ny_{1}}{m+n}}\right)}[/tex]

where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.

The midpoint is calculated by:

[tex]{\displaystyle Q=\left({\dfrac {x_{1}+x_{2}}{2}},{\dfrac {y_{1}+y_{2}}{2}}\right)}[/tex]

where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.

Now the given co-ordinates of the points are C(5, 2) and the midpoint is E(-1 , 0). Now to find the co-ordinates of D we have to use the midpoint formula.

Let the co-ordinate's of D be (a , b) then by using the above midpoint formula we get:

-1 = (5+a) ÷ 2

or, a = -2 -5

or, a = -7

again

0 = (2+b) ÷ 2

or, b = -2

Hence the co-ordinates of D is (-7 , -2)

Find the circumference of the circle use 3.14 for
Pi Round to the nearest hundred put the answer in cm

Need ASAP if u don’t know the answer don’t answer

Answers

Answer:

47.1 cm

Step-by-step explanation:

The circumference of a circle is denoted by C = 2πr, where r is the radius.

Here, we see that the given radius is 7.5, so r = 7.5 cm. We also are given that we need to use the approximation 3.14 for π, so plug all these into the formula:

C = 2πr

C = 2 * 3.14 * 7.5 = 47.1

To round this to the nearest hundredth... well, there's no hundredth place, so we can leave this as is or just write 47.10 cm.

Thus, the circumference is 47.1 cm.
