Tim explained a function in words and Paul wrote an equation. Tim: The amount of money in a savings account increases at a rate of $225 per month. After eight months, the bank account has $4,580 in it. Paul: y−1,400=56(x+26)
Whose function has the smaller y-intercept?
A. Tim’s with a y-intercept of $2,700
B. Paul’s with a y-intercept of $2,856
C. Paul’s with a y-intercept of $2,800
D. Tim’s with a y-intercept of $2,780

Answers

Answer:

D. Tim’s with a y-intercept of $2,780

Step-by-step explanation:

The function with the smaller y-intercept is Tim’s with a y-intercept of $2,780

The equation of Paul's savings is given as:

y-1400=56(x+26)

Set x to 0, to calculate the y-intercept

y-1400=56(0+26)

Evaluate the sum

y-1400=56(26)

Evaluate the product

y-1400=1456

Add 1400 to both sides

y = 2856

For Tim, we have the following equation

y = 225x + c

Where c represents the y-intercept

After eight months, the bank account has $4,580

So, we have:

4580 = 225*8 + c

Evaluate the product

4580 = 1800 + c

Subtract 1800 from both sides

c = 2780

2780 is less than 2856

Hence, the function with the smaller y-intercept is Tim’s with a y-intercept of $2,780

If there are 7 frankfurters to the pound, how
many pounds of frankfurters are needed for a
picnic to supply 19 pupils with 2 frankfurters
each?​

Answers

Answer:

6lbs

Step-by-step explanation:

Total # of Frankfurters needed.

[tex]19*2=38[/tex]

Divide the total needed by the amount in a lb, to find out how many lbs we need.

[tex]\frac{38}{7}=5.4[/tex]

Therefore, we need 6 full lbs in order to create at least 38 Frankfurters.

If we only have 5lbs, we can only create 35 Frankfurters.

5.4 pounds of frankfurters are needed for a picnic.

there are 7 frankfurters to the pound

let x pounds of frankfurters needed for a picnic. to supply 19 pupils with 2 frankfurters each.

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

since there are 19 pupil and each of has 2 frankfurters.

total frankfurters = 19 x 2
= 38
required pound,
x =38/7
x = 5.4  

Thus, 5.4 pounds of frankfurters are needed for a picnic to supply 19 pupils with 2 frankfurters each.

Answer:

(a) 26.43%

(b) 189 seconds

Step-by-step explanation:

(a) Data

mean: 3 minutes and 48 seconds = 3*60 + 48 = 228 s standard deviation, sd: 19 svalue of interest, x: 4 minutes = 4*60 = 240 s

Z-score is calculated as follows:

z = (x - mean)/sd

z = (240 - 228)/19

z = 0.63

We want to find the next probability P(Z>0.63), which is equivalent to 1 - P(Z≤0.63)

From table, 1 - P(Z≤0.63) = 1 - 0.7357 = 0.2643 or 0.2643*100 = 26.43%

(b) We want to find z1 at which P(Z≤z1) = 0.2. From the second table, z1 is between -2.05 and -2.06.

z = (x - mean)/sd

-2.055 = (x - 228)/19

(-2.055)*19 + 228 = x

x = 189 s

Which statement is true about the given function?
fx) > 0 over the interval (-0,3).
f(x) > 0 over the interval (-:-).
f(x) <0 over the interval (-0,3).
f(x) <0 over the interval (- : -).

Answers

Answer:

Option C.

Step-by-step explanation:

If the graph of a function f(x) lies above the x-axis, then f(x) > 0.

If the graph of a function f(x) lies below the x-axis, then f(x) < 0.

From the given graph it is clear that the graph of f(x) intersect the x-axis at x=3.

Before x=3 the graph lies below the x-axis. So,

[tex]f(x) < 0[/tex] over the interval [tex](-\infty,3)[/tex].

After x=3 the graph lies above the x-axis. So,

[tex]f(x) > 0[/tex] over the interval [tex](3,\infty)[/tex].

Therefore, the correct option is C.

Please Help Soon! A 4-foot by 8-foot rectangular piece of plywood will be cut into 4 congruent rectangles with no wood left over and no wood lost due to the cuts. What is the positive difference, in feet, between the greatest possible perimeter of a single piece and the least possible perimeter of a single piece?

Answers

Answer: 6 feet

Step-by-step explanation:

Given that a 4-foot by 8-foot rectangular piece of plywood will be cut into 4 congruent rectangles with no wood left over and no wood lost due to the cuts

Let assume that the 4 rectangles will be of the same area since they are congruent.

The area of the big rectangle will be

Area = 4 × 8 = 32

Divide 32 by 4

32/4 = 8

Suggest the two possible numbers in which their product will be equal to 8

4 and 2 or 8 and 1

If 4 and 2

The perimeter = 2L + 2B

Substitute the 4 and 2 into the formula

Perimeter = 2(4) + 2(2)

Perimeter = 8 + 4

Perimeter = 12

If 8 and 1

Perimeter = 2(8) + 2(1)

Perimeter = 16 + 2 = 18

The positive difference, in feet, between the greatest possible perimeter of a single piece and the least possible perimeter of a single piece will be:

18 - 12 = 6 feet

what is the volume of a right triangle with the dimesions 24 20 12

Answers

Answer:

Assuming you mean area the answer is 120

Step-by-step explanation:

a right triangle has too shorter sides who are perpendicular and one longer side that you can't use. the longer side is 24 since 24>20>12

so 24 is the hypontenuse (longer side)

the two perpendicular sides are 20 and 12

the area for a triangle is b*h*1/2

the base (20) times the height (12) is 240. 240 times 1/2 is 120.

Volume is half the base times height multiplied by the lateral height.
Meaning
V=(1/2(24)(20))*(12)
The base is 240.
You multiply the base times the material height which is 12
Therefore, the answer is 2880

Answer:

Taking 28 as the hypotenuse

If √ 7 ² + 14² = 28 then it's a right angled triangle

7 , 14 , 28 is not a right angled triangle.

Hope this helps you

Answer:

No

11x + 2 = 90

11x = 88

x = 8 which means that m∠B = 8x = 8 * 8 = 64°.
