Answer:
C. 6
Step-by-step explanation:
ΔADC and ΔACB are similar because two of their angles are congruent (∠ACD and ∠ABC, and ∠DAC and ∠CAB)
Because the sides are similar, you can create a proportion
[tex]\frac{AC}{AD}=\frac{AB}{AC}[/tex]
substitute the given values for the sides. AD=4 and AB=4+5=9
[tex]\frac{AC}{4}=\frac{9}{AC}[/tex]
cross multiply
[tex]AC^{2} =36[/tex]
take the square root of both sides
AC=6

A rectangular covered court has a length of 35m and a width of 20m. what
is the area of the covered court?
What is asked?
What are given?
What operation to be used?
What is the number sentence?
What is the answer?
Answer:
area of rectangle = 110 cm^2
Step-by-step explanation:
here's your solution
=> length of rectangle = 35 cm. [ given ]
=> width of rectangle = 20 cm. [ given ]
=> we need to find area ,
=> area of rectangle = 2(length + width)
=> area of rectangle = 2(35 + 20)
=> area of rectangle = 2*55 =
=> area of rectangle = 110 cm^2

Keisha, Boris, and Jose sent a total of 126 text messages over their cell phones during the weekend. Boris sent 4 times as many messages as Jose. Jose sent 6 fewer messages than Keisha. How many messages did they each send?
Answer:
Boris=504 keisha=120
Step-by-step explanation:
First you would start off by Multiplying 4x126 the result of that is= 504 so thats how much Boris sent. To get the answer to how many jose sent you simply just subtract 6-126 and that should result in 120

I think it’s 393.75 But not Sure can anyone confirm ? Or share the right answer
Answer:
$415.63
Step-by-step explanation:
it would have been 393.75, but he worked 5 hours overtime and got paid time and a half for it, meaning his normal pay plus half of it. (only for overtime tho).
so first calculate his normal pay:
40 × 8.75 = 350
then add overtime to it
8.75 × 5 = 43.75
43.75 × 1.5 = 65.625
65.625 + 350 = 415.625
round that and its 415.63!

Help plz it’s for grade recovery
Answer:
3.03 (if you're rounding to nearest hundredth, 3 if nearest whole/tenth.
please help, no links
Answer:
150
Step-by-step explanation:
Remark
The exterior angle = the sum of the two given interior angles. The first job is to solve for x and then use that to find the exterior angle.
Equation
83 + 6x + 7 = 15x
Solution
Combine like terms
90 + 6x = 15x Subtract 6x from both sides.
6x 6x
90 = 9x Divide both sides by 9
90/9 = 9x/9
x = 10
Now the exterior angle = 15x
Exterior angle = 15*10
Exterior angle = 150

The answer is b
saddsadsadas
Answer:
B
Step-by-step explanation:
Cause he added 24.76 more pounds to the 3.6 pounds. So you can take 24+3=27 and you might think C, but 0.76+0.6 that equals more than 1, so 27+1=28, and B has 28 as its answer, so its B
