Answer: 40 mph

Step-by-step explanation: let s = speed in traffic

(s+17) = out of traffic

:

Write a time equation; time = dist/speed

traffic time + normal speed time = 4 hrs

46%2Fs + 80%2F%28%28s%2B17%29%29 = 4

multiply by s(s+17) to cancel the denominators

46(s+17) + 80s = 4s(s+17)

46s + 782 + 80s = 4s^2 + 68s

126s + 782 = 4s^2 + 68s

Arrange as a quadratic equation on the right

2s^2 - 29s - 391 = 0

Use the quadratic formula a=2; b=-29; c=-391

I got a positive solution of

s = 23 mph in traffic

:

:

:

Check this by finding the actual times. Normal speed: 23 + 17 = 40 mph

46/23 = 2 hrs in traffic

80/40 = 2 hrs at normal speed

----------------------------

total time 4 hrs

0 = 4s^2 + 68s - 126s - 782

4s^2 - 58s - 782 = 0

simplify, divide by 2

so  the answer is 40mph

Answer:

12 and 24

Step-by-step explanation:

First, we need to list out the common multiples of 4 nd 6, less than 30

[tex]4 = 0.4,8,12,16,20,24,28[/tex]

[tex]6 = 0.6,12,18,24[/tex]

Then, we list out the common multiples

[tex]Common\ Multiple = 12,24[/tex]

Since, only 12 and 24 fall in this category.

Then the number is either 12 or farm

Answer: 63/50 meters^2 or in mixed number 1 13/50 meters^2

Step-by-step explanation:

area= length x width

length = 4 1/5= 21/5 . multiply the whole number with the denominator 4x5= 20 add 20 with the numerator 20+1=22

width = 3/10

21/5 x 3/10 ( multiply the denominators together)

21x3 / 5x10

= 63/50 meters^2 or in a mixed number 1 13/50 meters^2

(by the way I'm guessing you meant 3/10 and not 3/q0)

Answer:  C.  3π

Step-by-step explanation:

Since pi is irrational, (even multiples of pi) if π is added to any number, the sum is irrational.

The other choices are not irrational numbers.

√9 is 3    0.4444 repeating is the decimal equivalent of 4/9

2/7 is a fraction, and by definition all fractions with integers in the numerator and denominator [except 0] are rational numbers.

Answer:

L=W+12

2L+2W=48

2(W+12)+2W=48

2W+24+2W=48

4W=48-24

4W=24

W=24/4

W=6 ANS. FOR THE WIDTH.

L=6+12=18 ANS. FOR THE LENGTH.

PROOF:

2*18+2*6=48

36+12=48

48=48

Answer:

6 cm by 18 cm

Step-by-step explanation:

use x and x+12

2(x) + 2(x+12)=48

2x +2x+24=48

4x+24=48

4x=24

x=6 and (6+12)=18

Step-by-step explanation:

Answer:

p = $12,000

c = $4,500

b = $3,000

Step-by-step explanation:

Denote the variables as follows:

p = amount borrowed from parents

c = amount borrowed from the credit union

b = amount borrowed from the bank

The equations that can be formed using the given information are as follows:

p + c + b = 19500... (i)

p = 4b... (ii)

The formula to compute simple interest is:

SI = P × (R/100) × T

So, the equation for the total interest paid at the end of 1 year is:

0.05p + 0.04c + 0.03b = 870

5p + 4c + 3b = 87000... (iii)

Substitute (ii) in (i) and (iii) and simplify as follows:

4b + c + b = 19500

⇒ c + 5b = 19500... (iv)

5(4b) + 4c + 3b = 87000

⇒ 4c + 23b = 87000... (v)

Subtract (iv) from (v):

4c + 23b = 87000

(-)c + (-)5b = (-)19500 ] × 4

⇒

4c + 23b = 87000

-4c - 20b = -78000

⇒

3b = 9000

b = 3000

Compute the value of p as follows:

p = 4b = 4 × 3000 = 12000

p = 12000

Compute the value of c as follows:

p + c + b = 19500

12000 + c + 3000 = 19500

c + 15000 = 19500

c = 4500

Thus, the amount borrowed from each source is:

p = $12,000

c = $4,500

b = $3,000

Answer:

1600

Step-by-step explanation:

40 × 40 = 4 × 4 × 100 = 16 × 100 = 1600

(same amount of zeros behind the 1 as there are in the 40's together)

Answer: 15

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

range = biggest - smallest

121 - 83 = 38

range = 38

the correct answer is B: 38, representing the difference between the highest and lowest values in the data set, and it correctly reflects the range of the given IQ scores.

To find the range of the data set, we need to determine the difference between the highest and lowest values in the set. Given the IQ scores of the 10 adults as 83, 87, 90, 92, 93, 100, 104, 111, 115, and 121, the highest value is 121, and the lowest value is 83.

Thus, the range can be calculated as 121 - 83, which equals 38. Therefore, the correct answer is B: 38, representing the difference between the highest and lowest values in the data set, and it correctly reflects the range of the given IQ scores.

Step-by-step explanation:

Loretta Adman needs to find the center of the triangle  formed by the three roads.

What is Center, Incenter and Circumcenter of the triangle?

Incenter I, whose point is equidistant from the triangle's sides, and circumcenter O, whose point is equidistant from each of the triangle's vertices. A triangle center is a point in the plane that resembles the centers of squares and circles in some ways, meaning that it is roughly in the centers of the figure.

Given:  Three towns are linked by three straight roads.

Loretta Adman has created a three-sided billboard that she wants to position as close as possible to all three roads.

The center is in the middle of the figure by some measure.

Therefore, Loretta Adman needs to find the center of the triangle  formed by the three roads.

Answer:

A = [tex]\frac{b}{f^2+2H}[/tex]

Step-by-step explanation:

Given equation is,

b = f²A + 2HA

To solve this equation for the value of A we will isolate A in one side of the equation.

b = A(f² + 2H)

By dividing the equation by (f² + 2H) on both the sides of the equation.

[tex]\frac{b}{f^2+2H}=\frac{A(f^2+2H}{(f^2+2H)}[/tex]

A = [tex]\frac{b}{f^2+2H}[/tex]

Therefore, answer will be A = [tex]\frac{b}{f^2+2H}[/tex]
