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:
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.

Answer:
x=-7
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(3x+9)=24
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

[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.

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
Answer:
do r best the answer is i think is $151,113
