how can I solve this equation

49x^2 - 14x + 1 <= 0​

Answer:

45 minutes

Step-by-step explanation:

Change 3 hours to minutes

1 hours = 60 minutes

3 hours = 180 minutes

Using proportions

20 miles          5 miles

-------------   = ----------------

180 minutes      x minutes

Using cross products

20x = 5* 180

20x =900

Divide each side by 20

20x/20x = 900/20

x =45

45 minutes

Answer: 45 minutes

Step-by-step explanation: 20 miles in 180 minutes, 5 miles is 1/4 of 20 miles so you divide 180 by 4 which gives you 45

you would divide -> 51/68  and you would get .75. move the 2 first numbers after the dot to the front and you get 75%

Answer:

I the diagram, 17  represents 25% of the total  games. Since 17 times 3 equals 51, you use the first 3 columns to find the answer of 75%.  

Just took test that was the answer they gave.

Answer:

Step-by-step explanation:

A car traveled at a constant speed as shown in the graph.

Distance traveled is on the y-axis and duration of travel on the x-axis.

Point A(3.5, 210) shows,

Distance traveled = 210 miles

Time to travel = 3.5 hours

So the point (3.5, 210) shows the distance traveled by the car in 3.5 hours is 210 miles.

Slope of the line = speed of the car = [tex]\frac{\text{Distance traveled}}{\text{Time}}[/tex]

                           = [tex]\frac{210}{3.5}[/tex]

                           = 60 mph

Now we will find the speed of the car at another point B(1, 60).

If the speed of car is same as the point B as of point A, point B will lie on the graph.

Speed of the car at B(1, 60) = [tex]\frac{\text{Distance traveled}}{\text{Time}}[/tex]

                                             = [tex]\frac{60}{1}[/tex]

                                             = 60 mph

Hence, we can say that point B(1, 60) lies on the graph.

Answer:

25,

8:5

4:3

Step-by-step explanation:

you have to model it as a system of equations.

first, we know there are a total of 65 children, boys and girls. so

[tex]65 = b + g[/tex]

we also know there are 15 more boys than girls so

[tex]b = g + 15[/tex]

now, we can plug the second equation into the first to get

[tex]65 = (g+15)+g[/tex]

so

[tex]2g = 50, g = 25[/tex]

if g = 25, b must = 40, because it is g+15.

the ratio will be 40 boys to 25 girls. 40:25 or 8:5 if you simplify.

if there are 5 more girls, g = 25+5 = 30, so the ratio is 40:30 or 4:3.

Answer:

A) 25

B) 40 : 25

C) 40 : 30

Answer:

x + 3y + 9 = 0

Step-by-step explanation:

y=3x + 2

Coefficient of x = 3

Gradient (m) of line y= 3x + 2 is 3

Since the line passing through point

(3,-4) is perpendicular to line y=3x + 2

hence gradient (m) of the line is -1/3;

And hence it equation is given as;

y - y1 = m(x - x1)

y - (-4) = -1/3(x - 3)

multiplying through by 3;

3 × y + 3 × 4 = 3 × -1/3(x - 3)

3y + 12 = -1(x - 3)

3y + 12 = -x + 3

x + 3y + 12 - 3 = 0

x + 3y + 9 = 0

Answer:

9/12

Step-by-step explanation:

because I is the biggest number

Answer:

[tex]\frac{9}{12}[/tex] is the biggest

Step-by-step explanation:

I converted the fraction to a decimal by dividing the numerator by the denominator.

[tex]\frac{6}{9}[/tex] is 0.6... (6 is repeating)

[tex]\frac{9}{12}[/tex] is 0.75

When looking at these 2 decimals I know 0.75 is bigger.

Which means [tex]\frac{9}{12}\\[/tex] is the biggest.

Answer:

at 65 texts , co 2 costs more

19.99 + .25x > 35.99

x= number of texts

Step-by-step explanation:

19.99 + .25x = 35.99

x= number of texts

.25x= 35.99-19.99

.25x=16

x=16÷.25

x=64

Answer: 5/24

Step-by-step explanation:

The problem is 7/12-3/8. I got a common denominator of 24, then multipled 8 and 3 by 3, and 7 and 12 by 2. The problem is now 14/25-9/24, which equals 5/24

Answer:

440

Step-by-step explanation:

In other words, you know that 15 percent of a number is 66 and you want to know what that initial number is. Therefore, you can derive that 15 percent of 440 equals 66. 67 is 15 percent of what number?

Answer:

Option (3)

Step-by-step explanation:

If the two ratios are equivalent then the value of the ratios will be equal.

[tex]\frac{x_1}{y_1}=\frac{x_2}{y_2}[/tex]

Option (1)

[tex]\frac{11}{12}=\frac{44}{46}[/tex]

Simplified form of the fraction [tex]\frac{44}{46}[/tex] is,

[tex]\frac{44}{46}=\frac{22}{23}\times \frac{2}{2}=\frac{22}{23}[/tex]

Therefore, [tex]\frac{11}{12}=\frac{22}{23}[/tex]

Which is not true,

Therefore, option (1) doesn't show the equivalent ratio.

Option (2)

[tex]\frac{36}{40}=\frac{4}{9}[/tex]

Simplified form of [tex]\frac{36}{40}[/tex] is,

[tex]\frac{36}{40}=\frac{9}{10}\times \frac{4}{4}=\frac{9}{10}[/tex]

Therefore, [tex]\frac{4}{9}= \frac{9}{10}[/tex]

Which is not true.

Therefore, option (2) doesn't show the equivalent ratio.

Option (3)

[tex]\frac{1.5}{3}=\frac{12}{24}[/tex]

Since simplified form of [tex]\frac{1.5}{3}[/tex] is,

[tex]\frac{1.5}{3}=0.5[/tex]

And simplified form of [tex]\frac{12}{24}[/tex] is,

[tex]\frac{12}{24}=0.5[/tex]

Therefore, [tex]\frac{1.5}{3}=\frac{12}{24}=0.5[/tex]

Option (3) shows the equivalent ratios.

Option (4)

[tex]\frac{8}{12}=\frac{4}{24}[/tex]

Since, [tex]\frac{8}{12}=\frac{2}{3}\times \frac{4}{4}=\frac{2}{3}[/tex]

And [tex]\frac{4}{24}=\frac{1}{6}\times \frac{4}{4}=\frac{1}{6}[/tex]

But [tex]\frac{2}{3}\neq \frac{1}{6}[/tex]

Therefore, equation in this option doesn't show the equivalent ratios.
