Answer 1

Answer:

Step-by-step explanation:

in tri ADC and tri BDC

∠ADC =∠BDC = 90

DC is common

AD = BD (given)

triangle ADC ≅ tri BDC by SAS congruency

hence AC = BC by CPCT ( congruent parts of congruent triangles)

hence, BC = 13

Answer 2

Answer:

13

Step-by-step explanation:

in a proof, you could say that since AD is congruent to BD, since that is given to you, and angle ACD is congruent to angle CDB since a perpendicular bisector makes both sides a right angle, and CD is congruent to CD, (I forgot the reasoning for this part). after this, you can assume that triangle ACD is congruent to triangle CDB. and that would mean AC is congruent to CB because of CPCTC (Corresponding Parts of Congruent Triangles are Congruent), which would then mean that since AC is 13, CB would be 13 as well.

A banker earns a $75,000 annual salary, a 2.35% commission on any approved loans for the bank’s business customers, and a fee of $3.75 for each application processed. If the banker has a total of $2.8 million in approved business loans and processes 2,750 applications this year, what are the banker’s earnings rounded to the nearest dollar?

Answers

Answer:

Amount earned = $151,113

Step-by-step explanation:

Here, we are interested in calculating the banker’s earnings rounded to the nearest dollar;

We proceed as follows; we have the following;

1. Annual salary of $75,000

2. 2.35% on approved loans.

Approved loans = 2.8 million

Commission = 2.35/100 * 2.8 million = $65,800

3. $3.75 for each processed loan application

Total = 2750

Amount = 3.75 * 2750 = $10,312.50

Total amount earned is thus;

$75,000 + $65,800 + $10,312.50 = 151,112.5 = 151,113 to the nearest dollar

[tex]2a { }^{2} b {}^{2} - 7ab - 30[/tex]

Answers

Answer:

(ab - 6)(2ab + 5)

Step-by-step explanation:

Assuming you require the expression factorised.

2a²b² - 7ab - 30

Consider the factors of the product of the coefficient of the a²b² term and the constant term which sum to give the coefficient of the ab- term

product = 2 × - 30 = - 60 and sum = - 7

The factors are - 12 and + 5

Use these factors to split the ab- term

= 2a²b² - 12ab + 5ab - 30 ( factor the first/second and third/fourth terms )

= 2ab(ab - 6) + 5(ab - 6) ← factor out (ab - 6) from each term

= (ab - 6)(2ab + 5) ← in factored form

In January, a city’s snowfall was 5/8 foot below the historical average. In February, the snowfall was 3/4 foot above the historical average. Was the city’s snowfall in the two-month period above or below the historical average? By how much?

Answers

Answer:

The city's snowfall in the two-month period was above the historical average by 1/8 feet

Step-by-step explanation:

Fractions

The question provides the following information: In January, a city’s snowfall was 5/8 feet below the historical average. Let's assume the snowfall level to be positive if it's above the historical average and negative otherwise.

The data from January gives us a snowfall of -5/8 feet because it was below the average.

We also know in February, the snowfall was 3/4 foot above the historical average. Following our predefined convention, the data from February gives us a snowfall of +3/4 feet.

To know if the city's snowfall during the two-month period was above or below the historical average, we just need to add them, signs included.

If the result is negative, the two-month period showed a snowfall below the historical average.

Let's find the sum of

[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}[/tex]

The LCM of 4 and 8 is 8, thus:

[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}=\frac{-5+2*3}{8}=\frac{1}{8}[/tex]

Since this quantity is positive, we can say the city's snowfall in the two-month period was above the historical average by 1/8 feet.

Step 1: Simplify both sides of the equation.

−2(3x+9)=24

(−2)(3x)+(−2)(9)=24(Distribute)

−6x+−18=24

−6x−18=24

Step 2: Add 18 to both sides.

−6x−18+18=24+18

−6x=42

Step 3: Divide both sides by -6.

−6x /−6

= 42 /−6

1. given w(x)=4x
a. graph r(x)=4 x w(x). then complete the table of corresponding points on r (x).

Answers

Answer:

Step-by-step explanation:

a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically  stretched by a scale factor of 4.

Table for the corresponding points will be,

x               w(x)                  r(x)

0                0                  0×4 = 0

15              60               60×4 = 240

30             120             120×4 = 480

45             180             180×4 = 720

b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).

c). Since, w(x) = 4x

   and r(x) = 4[w(x)]

   r(x) = 4(4x) = 16x

  r(x) = 16x

HELPPPPPText (for the second one)The captains needed to keep the slaves in acceptable physical condition if they were to be sold at high prices, so each morning after breakfast the slaves were danced on deck, in order to give them exercise. Still shackled together, the men were forced to jump up and down until often the flesh of their ankles was raw and bleeding from the iron chains from which bound them together. The women and children, who were free of such bonds were better able to dance to the rhythm that was pounded out on an African drum or iron kettle, sometimes with the accompaniment of a fiddle or African banjo played by a crew member. The slaves, otherwise kept miserable in the tween decks, enjoyed this dancing, as it was their only form of physical recreation during the entire day. Each day at sunset the slaves would be placed back below deck to rest in the misery and filth that was the tween decks. QUESTION:2.

Also during periods of inclement weather the slaves were not fed as usual.

At this time the men would be shackled together with iron chains, while the women and children would be allowed to roam about on deck. At about nine o clock in the morning they were given their first meal of the day. Interestingly, slaves from different sections along the West African coast would often be fed different meals. Those from the Northern part of the Guinea coast would be fed boiled rice, millet, or cornmeal. Slaves from the Bight of Biafra had stewed yams, and those from still farther south in the Congo River region would be fed starchy manioc, cassava flour, or banana-like fruits. Sometimes a few lumps of raw meat would be thrown in with their food to keep them healthy. It was also at this time in the morning that the slaves were given their daily ration of a half-pint of water in a small pan, called a pannikin.In the late afternoon came the slaves second and only other meal of the day.
