Answer:

after 4 hours she cycled 48+ 20 which is 68 miles

Step-by-step explanation:

Answer:

So, d(4)=68. That means that after 4 hours, Joanna has cycled 68 miles.

Step-by-step explanation:

First, we need to find what d(4) equals. In this equation t=4, so to solve plugin 4 and simplify.  Therefore, the equation is [tex]d(4)=12(4)+20[/tex]. Once you multiply and add you get d(4)=68; this answers the first question.

Then, the next two questions ask you to interpret this answer. To do that go back and read what each variable stands for. "t" is for the time Joanna has cycled. So, in the equation d(4), 4 hours have passed. Additionally, "d(4)" represents the number of miles she has ridden. This means since d(4)=68 she has cycled 68 miles.

Note that since I cannot see the options I guessed at the exact wording, but the answers should be similar to what I wrote.

Answer:

y=5/4x-5

Step-by-step explanation:

Hi there!

The equation of the line is typically written as y=mx+b, where m is the slope and b is the y intercept

Perpendicular lines have slopes that are negative and reciprocal. If they are multiplied together, the result is -1

So let's find the slope of the perpendicular line with this formula:

-4/5m=-1

multiply both sides by -5/4 (we need to isolate m onto one side, and -4/5*-5/4=1)

m=5/4

So the slope of the new line is 5/4

Here's the equation so far:

y=5/4x+b

now we need to find b

Because the equation of the line passes through (0,-5), we can use it to solve for b

substitute 0 as x and -5 as y

-5=5/4(0)+b

-5=0+b

-5=b

Therefore the equation of the line is:

y=5/4x-5

Hope this helps!

Answer:

0.91

Step-by-step explanation:

The scatterplot shows a strong positive correlation which almost forms a perfect line.

The most appropriate correlation would be 0.91.

If the correlation was 0.21 then the plots would be more scattered.

Hope this helps you.

Answer:

x - y = 4

Step-by-step explanation:

Given

y = x - 4 ( add 4 to both sides )

y + 4 = x ( subtract y from both sides )

4 = x - y , that is

x - y = 4 ← in standard form

Answer:

positive

Step-by-step explanation:

negative slopes go from right to left; this line goes from left to right

0; the line isn't completely horizontal

undefined; the line isn't completely vertical

Answer:

D. Zero product of multiplication

Step-by-step explanation:

The given equation is presented as follows;

Given: x² + 6·x + 8 = 0

By factorization, to find numbers represented by variables, 'a' and 'b', such that  a + b = 6 and a×b = 8, we have, a = 2, and b = 8 as a possible solution by observation

Step 1: (x + 2)·(x + 4) = 0

Given that (x + 2) × (x + 4) = 0, we have

Step 2: x + 2 = 0 or x + 4 = 0, by zero product of multiplication

The zero-product property states that the when two non zero numbers are multiplied, the result is nonzero

Therefore, when two numbers are multiplied, and have a result of zero, for example, i × j = 0, then, either, i = 0, or j = 0

By the zero-product rule, either, (x + 2) = 0, or (x + 4) = 0

Therefore, we have;

Therefore;

Step 3: x = -2 or x = -4

The property of real numbers Felipe's use for step 2 is the Zero product of multiplication.

Angle APE is exterior to APD

because it's outside angle APD

Answer:

28, 44, 22

Step-by-step explanation:

a+b+c = 94

2×c = b

a = c+6

=>

c+6 + 2×c + c = 94

4×c + 6 = 94

4×c = 88

c = 22

=>

b = 2×22 = 44

a = 22 + 6 = 28

Answer:

b=57° (vertically opposite angles)

Step-by-step explanation:

57°+a+b+c=360° (angles around a point)

57°+57°+a+c=360°

114°+a+c=360°

a+c=360°-114°=246°

a=c (vertically opposite angles)

therefore 2a=246°

a=123°

b=123°

Answer: $1640

Step-by-step explanation:

Since the salesperson's commission rate is 4%, therefore the commission from the sale of $41,000 worth of furnaces will be calculated as follows:

= 4% × $41000

= 4/100 × $41000

= 0.04 × $41000

= $1640

Therefore, the commission is $1640.

Answer:

Step-by-step explanation:

The perimeter is the sum of the side lengths. Those that are unmarked are assumed to match the length of the nearest parallel side.

Clockwise from upper left, the perimeter is ...

  P = 8 + 5 + 4 + 4.5 + 15 + 5.6 + 4 + 5

  P = 51.5 . . . feet

__

The area can be figured using the formulas for area of a parallelogram, rectangle, and trapezoid. These are, respectively, ...

parallelogram area = (8 ft)(3 ft) = 24 ft²

rectangle area = (8 ft)(4 f) = 32 ft²

trapezoid area = (1/2)(8 ft +15 ft)(4 ft) = 46 ft²

Then the total area of the figure is ...

  A = 24 ft² +32 ft² +46 ft²

  A = 102 ft²

_____

Additional comment

The figure shown is impossible. The trapezoid side lengths and height are consistent with a bottom base of length 14, not 15.

Answer:

The answer is C because 14 - 3 = 11 x 2 = 22

Answer:

C

Step-by-step explanation:

Knowing x=14, we will substitute 14 when we see x.

In the equation 2(x-3) =22, when we substitute 14 for x we get 2(14-3)=22

Following PEMDAS, we do what's in the parenthesis first. 14 minus 3 gives us 11 and multiplying that by 2 will give us 22.

22=22 is true and therefore, C is your correct option.
