Answer:
D) 5/2
Step-by-step explanation:
Scale factor = AB/DE = 35/14 = 5/2
The scale factor from ΔABC to Δ DEF is, 5 / 2
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
We have to given that;
The figure of ΔABC to Δ DEF is shown in image.
Now, We can formulate for the scale factor,
⇒ AB / DE
⇒ 35 /14
⇒ 5 / 2
Thus, The scale factor from ΔABC to Δ DEF is, 5 / 2

sally is taking a test
when she got her score it was 85% of 100% how many questions was on the test and how many did she get wrong
Answers
Answer:
There was 20 questions on the test.
She got 3 wrong.
Step-by-step explanation:
[tex]\frac{85}{100} = \frac{17}{20}[/tex]
20 - 17 = 3
There was 20 questions on the test.
She got 3 wrong.
First of all, you need to simplify 85/100.
85/100 / 5/5 = 17/20.
Now that you know how many questions were on the test, subtract 17 from 20.
20 - 17 = 3
So in conclusion, the test had 20 questions and she missed three.
But this question doesn’t have enough info to be honest, if you multiply 17/20 with any number it’s still going to be 85%.
At a local ice cream parlor, there are 6 different flavors of ice cream from which to select (strawberry, chocolate, vanilla, rocky road, mint chocolate chip, and peanut butter). Each ice cream sundae must include 2 different flavors of ice cream; what is the probability that the next customer's sundae will have vanilla and chocolate (in either order)
Answers
Answer:
1/30
Step-by-step explanation:
let, vanilla be the first ice cream.
hence, the probability of choosing vanila= 1/6
let, chocolate be the second ice cream.
hence, the probability of choosing chocolate=1/5
hence, the probability that the next customer's sundae will have vanilla and chocolate (in either order)= (1/6)×(1/5)
=1/30

Answer:
17° and 73°
Step-by-step explanation:
For two complementary angles, the sum of angles is equal to 90 degrees.
Let other angles = x
First angle = 5+4x ...(1)
ATQ,
5+4x+x=90 ...(2)
Equation (1) and (2) shows the equations for the given problems.
5+5x=90
5x = 85
x = 17°
Other angle = 17
First angle = 5+4x
= 5+4(17)
= 73°
So, the other two angles are 17° and 73° respectively.

What is work and time relationship?Work is the effort applied to produce a deliverable or accomplish a task. A certain amount of time (T) is taken to complete a certain work (W).
Work Done = Time Taken × Rate of Work.
Rate of Work = 1 / Time Taken.
Time Taken = 1 / Rate of Work.
According to the question
Dan and Joan were able to clean the attic in 7 hours together
i.e
Rate of Dan = D
Rate of Joan = J
now,
Rate of Work = 1 / Time Taken.
D + J = [tex]\frac{1}{7}[/tex]
It takes Joan 9 hours to complete the same job alone
i.e
J = [tex]\frac{1}{9}[/tex]
Rate of Dan :
D + J = [tex]\frac{1}{7}[/tex]
D + [tex]\frac{1}{9}[/tex] = [tex]\frac{1}{7}[/tex]
D = [tex]\frac{1}{7}[/tex] - [tex]\frac{1}{9}[/tex]
D = [tex]\frac{2}{63}[/tex]
Therefore , Time taken by Dan to complete the same job
As,
Time Taken = 1 / Rate of Work.
Time taken by Dan = [tex]\frac{63}{2}[/tex]
= 31.5 hr
Hence, It would take 31.5 hours for Dan to complete the same job.

AE = 3x - 2 and EC = 2x + 3 then DB =
#5
Answers
Answer:
DB = 26
Step-by-step explanation:
Remember:
AE ≅ ECAC ≅ DB☆The equation in finding the value of x would be 3x - 2 = 2x + 3.
☆Let's solve the equation.
[tex] \: \: \: \: \: \: \: \: \: 3x - 2 = 2x + 3 \\ \frac{ - 2x \: \: \: \ = - 2x}{x - 2 = 3} \\ \frac{ \: \: \: \: \: + 2 = + 2}{x = 5} [/tex]
☆Now that we found the value of x, we are going to plug in for AE and EC.
[tex]AE ; \\ 3x - 2 \\ 3(5) - 2 \\ 15 - 2 \\ 13 \\ \\ \\ \\ and \\ \\ \\ \\ \\ EC; \\ 2x + 3 \\ 2(5) + 3 \\ 10 + 3 \\ 13[/tex]
☆AE and EC each measure 13. To find the length of AC, you will have to add AE and EC. [tex]13 + 13 = 26[/tex]
The length of AC is 26. And since we know that AC is congruent (equal) to DB, meaning they measure the same. DB length is also 26.

[tex]DM=12[/tex]
Step-by-step explanation:
(Let the point where the altitude from [tex]D[/tex] intersects [tex]AB[/tex] be called as point [tex]E[/tex].) First, let's find the area of parallelogram [tex]ABCD[/tex]. The area of a parallelogram is simply [tex]b*h=bh[/tex], where [tex]b[/tex] is the parallelogram's base and [tex]h[/tex] is the parallelogram's height. If we let [tex]AB[/tex] and [tex]DE[/tex] be the base and height respectively, since we are already given their lengths, we know that the area of parallelogram [tex]ABCD[/tex] will be [tex]AB*DE=15*8=120[/tex].
Now, how does this information matter, you might ask? Well, we can take either [tex]AB[/tex] or [tex]CB[/tex] to be the base and either [tex]DE[/tex] or [tex]DM[/tex] to be the height. In this case, let's take the latter two options, as we are looking to find the length of [tex]DM[/tex].
Therefore, we know that the area of parallelogram [tex]ABCD[/tex] can also be found by calculating [tex]CB*DM[/tex]. Since we know the values of the area and [tex]CB[/tex], we can write the following equation to solve for [tex]DM[/tex]:
[tex]Area = CB*DM[/tex]
[tex]120=10*DM[/tex] (Substitute [tex]Area=120[/tex] and [tex]CB=10[/tex] into the equation)
[tex]\frac{120}{10}=\frac{10*DM}{10}[/tex] (Divide both sides of the equation by [tex]10[/tex] to get rid of [tex]DM[/tex]'s coefficient)
[tex]12=DM[/tex] (Simplify)
[tex]DM=12[/tex] (Symmetric Property of Equality)

If your gross monthly income will be $3,750, you need to determine the net pay for your monthly budget. Your monthly net pay is
Answers
Answer:
$2,989.12
Step-by-step explanation:
The correct answer to the given question is $2,989.12. The monthly net pay is $2,989.12, when the gross monthly income is $3,750.
The deduction from the gross income is almost 20.29%.
The gross income is multiplied by 20.29% and then the answer is deducted from the gross income which gives monthly net pay as a result
$3,750 * 20.29% = $760.875
$3,750 - $760.875 = $2,989.12
Your monthly net pay is $2,989.12
