Answer:

C. 4.24 miles/hour

Step-by-step explanation:

We know that,

Speed =\frac{Distance}{Time}

Given,

Distance covered by Abigail in jogging =  10.6 miles,

Time taken by her = 2.5 hours,

Therefore, her speed of jogging = \frac{10.6}{2.5}=4.24\text{ miles per hour}

Option 'C' is correct.

2. The food pantry of Ellicottville received a huge donation of fruit snacks during the month of December. The table below shows
mestny [16]

ANSWER

238\text{ fruit snacks per after-school program}

EXPLANATION

We have that there are 12 after school programmes and each one got an equal number of packages.

To find the number of fruit snacks that each received, we have to find the total number of fruit snacks.

The total number of fruit snacks can be found by multiplying the number of boxes of each flavor by the number of packages in each box, then adding them up:

\begin{gathered} \text{TOTAL}=(48\cdot4)+(78\cdot9)+(90\cdot11)+(108\cdot9) \\ \text{TOTAL}=192+702+990+972 \\ \text{TOTAL}=2856\text{ fruit snacks} \end{gathered}

Now, to <em>find the number of fruit snacks that each received</em>, divide by 12:

\begin{gathered} \frac{2856}{12} \\ 238\text{ fruit snacks per after-school program} \end{gathered}

identify the graph of 9x^2-25y^2=225 for t(0 5) and write an equation of the translated or rotated graph in general form
tamaranim1 [39]

ANSWER

The required equation is:

9 {x}^{2}  - 25{y}^{2}  + 250y  - 85 0=0

EXPLANATION

The given equation is

9 {x}^{2}  - 25 {y}^{2}  = 225

Dividing through by 225 we obtain;

\frac{ {x}^{2} }{25}  -  \frac{ {y}^{2} }{9}  = 1

This is a hyperbola that has it's centre at the origin.

If this hyperbola is translated so that its center is now at (0,5).

Then its equation becomes:

\frac{ {(x - 0)}^{2} }{25}  -  \frac{ {(y - 5)}^{2} }{9}  = 1

We multiply through by 225 to get;

9 {x}^{2}  - 25( {y - 5})^{2}  = 225

We now expand to get;

9 {x}^{2}  - 25( {y}^{2} - 10y + 25 )= 225

9 {x}^{2}  - 25{y}^{2}  + 250y  - 6 25 = 225

The equation of the hyperbola in general form is

9 {x}^{2}  - 25{y}^{2}  + 250y  - 85 0=0

Two brothers, Mark and Walter, each inherit $20000. Mark invests his inheritance in a savings account with an annual return of 2
Igoryamba

Answer:

$720

Step-by-step explanation:

$20000 - 100%

$x. - 2.5%

x=(20000*2.5)/100=500

20000+500=$20500 in one year (Mark)

20000 - 100

x. - 6.1

x= (20000*6.1)/100 = 1220

20000+1220= $21220 (Walter)

21220-20500= $720 more (Walter will have after 1 year)
