A bird flies 5 miles per hour for 2 hours.

How far, in feet, does the bird travel in 2 hours?

Answer:

10.3 m/s

Step-by-step explanation:

Speed = Distance / Time

100 metres travelled in 9.7 seconds means that her speed was 100/9.7 metres per second, which is 10.30927... rounded to 10.3 metres per second.

Answer:

6ft by 40ft

Step-by-step explanation:

Perimeter = 2(L+W)

Area = LW

L is the length of the fence

W is the width

Given

P = 68ft

A = 240ft²

Substitute into the formula

68 = 2L+2W ... 1

240 = LW... 2

From 1;

34 = L+W

L = 34-W ... 3

Substitute 3 into 2

From 2;

LW = 240

(34-W)W = 240

34W - W² = 240

- W²+34W = 240

W²-34W - 240 = 0

W²+6W-40W - 240 = 0

W(W+6)-40(W+6) = 0

W-40 = 0

W = 40feet

Since

34 = L+W

34 = L + 34

L = 6ft

Hence the dimension of the fence is 6ft by 40ft

Answer:

x = 17, -3

Step-by-step explanation:

I'm not sure why this is the answer I only know because I've had it before

pretty sure you have to use (b/2) ^2

The complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.

Rearranging the equation x² - 51 = 14

x²- 14x -51 = 0
x² - 14x + 49 - 49 - 51 = 0
(x - 7)² = 100
x - 7 = √100
x - 7 = ± 10
Taking RHS positive,
x - 7 = 10
x = 17
Taking RHS negative
x - 7 = -10

x = 7 - 10
x = -3

Thus, the complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.

11/18 which is 6.11

Step-by-step explanation:

Answer:

Y=-5.6

x=.9

Step-by-step explanation:

Isolate the x:

6x=11+y

2x=7-3y

multiply top by 3 to get rid of y(3y and -3y cancel each other out)

18x=11

2x=7

put them together:

20x=18

divide by 20

x=0.9

to find y plug in x to the first equation:

y=6(.9)-11

y=5.4-11

y=-5.6

Answer:

8 dimes

Step-by-step explanation:

A quarter is $0.25, so 0.25 should be multiplied by the number of quarters she has:

0.25 * 12 = 3.00

A nickel is $0.05, so 0.05 should be multiplied by the number of nickels she has:

0.05 * 7 = 0.35

If we add this together, we get 3.35, and the rest of the money Courtney has is in dimes. First, find the amount of money left:

4.85 - 3.35 = 1.50

A dime is $0.10, so divide the amount of money left by 0.10 to find the number of dimes Courtney has:

1.50 ÷ 0.10 = 15

Subtract 15 by the number of nickels Courtney has to find how many more dimes she has than nickels:

15 - 7 = 8 dimes

hi

Step-by-step explanation:

Answer:

The length and breadth of the fence are 80 and 70 meters, respectively.

Step-by-step explanation:

Let suppose that fencing has a rectangular form. The length to breadth ratio is [tex]\frac{8}{7}[/tex]. Dimensionally speaking, the total cost for fencing the plot ([tex]C[/tex]), measured in monetary units, is the product of perimeter of the rectangle ([tex]p[/tex]), measured in meters, and unit cost ([tex]c[/tex]), measured in monetary units per meter, that is:

[tex]C = c\cdot p[/tex] (1)

[tex]C = 2\cdot c\cdot (w+l)[/tex] (2)

Where:

[tex]w[/tex] - Breadth of the fence, measured in meters.

[tex]l[/tex] - Length of the fence, measured in meters.

By applying the ratio described above, we reduce (2) into this form:

[tex]C = 2\cdot c\cdot \left(\frac{1}{r} +1\right)\cdot l[/tex] (3)

Where [tex]r[/tex] is the length to breadth ratio, no unit.

If we know that [tex]C = 60000[/tex], [tex]c = 200[/tex] and [tex]r = \frac{8}{7}[/tex], then the length and breadth of the rectangle are, respectively:

[tex]l = \frac{C}{2\cdot c\cdot \left(\frac{1}{r} +1\right)}[/tex]

[tex]l = \frac{60000}{2\cdot (200)\cdot \left(\frac{7}{8}+1 \right)}[/tex]

[tex]l = 80\,m[/tex]

[tex]w = \frac{l}{r}[/tex]

[tex]w = \frac{80\,m}{\frac{8}{7} }[/tex]

[tex]w = 70\,m[/tex]

The length and breadth of the fence are 80 and 70 meters, respectively.

Answer:

other root: x = 9

p = 7

Step-by-step explanation:

first, find p:

(8)² - (3p - 4)8 + 11p -5 = 0

64 - (24p - 32) + 11p - 5 = 0 –––––> 64 - 24p + 32 + 11p - 5 = 0

91 - 13p = 0

-13p = -91

p = 7

plug in p to find the polynomial:

x² - (3(7) - 4)x + 11(7) - 5 = 0

x² - (21 - 4)x + 77 - 5 = 0

x² - 17x + 72

find the roots:

we know that 8 is one of the roots, so one factor is (x - 8)

the other number needs to be something that equals -17 when added with -8 and 72 when multiplied by -8

that number is -9

so the poly nomial factors to be: (x-8)(x-9)

so the roots are x = 8 and x = 9

Answer:

p = 7

Step-by-step explanation:

x²-(3p-4)x+11p-5=0    ...(1)    Root: 8, x-8 is factor

(x-8) (x- (11p-5)/8) = 0

x² -8x - ((11p-5)/8)*x + (11p-5) = 0

x² - (8 + (11p-5)/8) x + 11p-5 = 0   ----(2)

compare(1) and (2): 3p-4 = 8 + (11p-5)/8

24p - 32 = 64 + 11p - 5

13p = 91

p = 7

check: x²-(3p-4)x+11p-5 = x²- 17x + 72 = (x-8)(x-9)

Answer:

Multiply both the divisor and the dividend by 10 to make it easier to divide

Step-by-step explanation:

As given division equation in a more suitable format that shows the dividend and the divisor that is = [tex]\frac{5.72}{0.52}[/tex]

so now we we will make the two parts to be whole number

first factor to muliply both dividend and divisor by is looking at their decimal place as they both have two decimal places

so, that we multiplying both of them by a 10 will make them whole numbers

so so correct answer is 10

[tex]\frac{5.72\times 10}{0.52 \times 10} =[/tex]  11
