Can anyone help me? I'm pretty puzzled

Answer: 16:24

Step-by-step explanation:

add the ratio so 2+3=5

Divide from 40 so 40/5=8

multiply by individual ratios

2*8:3*8= 16:24

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:

[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]

Answer: the answer is 66

Step-by-step explanation: 180-90-24=66

Well the sum of all the angles of a triangle is 180˚ so 24+90=114˚

180˚-114˚=66˚.

Answer:

this is not a real triangle

Step-by-step explanation:

Answer:

The formula for the volume of a cylinder = height x π x (diameter / 2)^2

volume = 18 x π x (8/2)^2

volume = 502.654825 cm^3

volume = 502.7 cm^3

Answer:

10 x 21 = 210 divided by 2 = 105 x 2 = 210

Answer:

10 x 21 = 210 divided by 2 = 105 x 2 = 210

Step-by-step explanation:

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

Answer:

Angle ADC = 80 degrees

Step-by-step explanation:

Here, we want to find the measure of angle ADC

mathematically, sum of angles at a point is 360

Thus;

x + 3x + x + 10 = 360

5x + 10 = 360

5x = 360-10

5x = 350

x = 350/5

x = 70

From the diagram;

angle ADC is (x + 10)

so we have; (70 + 10) = 80 degrees

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:

2x+3y=9

2x+2-3y+1=8

2x-3y=8

2x-3y+3y=8+3y

2x=8+3y

2x=8+3y

2      2

x=8+3y

    2

2(x) +3y=9

2* (8+3y)/2 +3y=9

(16+6y)/2)+3y=9

2*(16+6y)/2)+3y=9

16+6y+6y=18

6y+6y=18-16

12y=2

12y = 2

12      12

y=2

  12

y=0.16666666666667

2x+3 (0.16666666666667)=9

2x+0.5=9

2x=9-0.5

2x=8.5

2x = 8.5

2       2

x=8.5

x=4.25

Answer:

(5,-3) *red* i cant tell wht it says very well

Step-by-step explanation:

Answer:

See below, please!

Step-by-step explanation:

We can set up a system of equations to model this problem. Let's consider the student's ticket as x, and y for the adult ticket.

So since the student ticket is $1.50, and adult is $4, we can set up the following equation: [tex]1.5x+4y=5050[/tex], since they collected $5050 total.

We can set up another equation modeling the number of people who came to the game. This would be x+y=2200.

Solve this, and we get x= 1500 and y=700. So, they sold 1500 student tickets and 700 adult tickets.

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: C. 113.1 cubic centimeters

Step-by-step explanation:

Volume of a sphere= [tex]\frac{4}{3}[/tex](3.14)(r)^3

Since we know r then just plug in to get 4/3(3.14)(3)^3= 113.1

So the answer is C

Answer:

  50°

Step-by-step explanation:

Angle DEG is also angle DEC. It subtends arc DC as does inscribed angle DFC. Inscribed angles that subtend the same arc have the same measure.

Answer: $120

Step-by-step explanation:

Assume the original price is x.

He sold the scooter for $130 and this was $50 less than 1.5 times what he paid for it.

Relevant formula is therefore:

1.5x - 50 = 130

1.5x = 130 + 50

x = 180/1.5

x = $120
