Can someone pls help meee

Answer:

AC equals CB times CD all over CE

The lengths of the sides of the scaled drawing can be determined from the

relation between similar triangles.

The expression that will help Jolene determine the length segment AC is the option;

Reasons:

The given parameters are;

The figure Jolene is trying to create = A scaled up blue print

Given that in ΔACB and ΔABC, we have;

DE and AB are parallel

Therefore;

∠CED ≅ ∠CBA by corresponding angles

∠CDE ≅ ∠CAB by corresponding angles

∠C ≅ ∠C by reflexive properties

ΔCDE ~ ΔACB by Angle-Angle similarity postulate

Therefore, by similar triangles, and triangle proportionality, we have;

[tex]\displaystyle \frac{AC}{CD} = \mathbf{\frac{CB}{CE}}[/tex]

Therefore;

[tex]\displaystyle CD= \mathbf{ \frac{CB\cdot CD}{CE}}[/tex]

Therefore, if segments DE and AB are parallel, the expression that will help Jolene determine the length segment AC is; [tex]\displaystyle CD= \frac{CB\cdot CD}{CE}[/tex]

Answer:

Car a is moving at 15 miles per hour

Its slope is 15/1

Its equation is y = 15x

Car b is moving at 7.5 miles per hour

Its slope is 7.5

Its equation is y = 7.5x

Car a is moving twice as fast as car b

Step-by-step explanation:

But here's how you solve

Chose 2 points and find the change in y and change in x, then divide in the same order.

Point 1: (1, 15)

Point 2: (2, 30)

Change in y = 15

Change in x = 1

y = miles

x = hours

15 miles/1 hour

You can also do this

Pick a point and just divide it's y by its x. For example:

(4, 60)

60 miles/4 hours

15 miles per hour

Now that we have the slope, we can get the equation for the graph:

y = 15x + 0

or just y = 15x, because there is no y-intercept

Now let's solve for car b:

Chose a point:

(3, 22.5)

Divide its y by its x

22.5/3

7.5

Car b is moving at 7.5 miles per hour

Now that we have the slope, we can get the equation for the graph:

y = 7.5x + 0

or just y = 7.5x, because there is no y-intercept

Compare the speeds

Car a: 15 mph

Car b 7.5 mph

15 > 7.5

So, Car a > Car b

15/7.5 = 2

So Car a moves twice as fast as Car b

Answer:

70 people

Step-by-step explanation:

30 dollars for each person, so you divide 2,100 by 30 to find how many people.

2,100/30=70

Answer:

70

Step-by-step explanation:

Target=$2,100

Money Earned from a single person=$30

Number of persons=$2,100 /$30 = 70

Thus, 70 people need to attend their breakfast in order to raise $2,100

Answer:

11th term is 0

Step-by-step explanation:

30, 27 , 24 ,......0

a = first term = 30

Common difference = second term - first term = 27 - 30 = -3

nth term = a+(n-1)*d

a + (n-1)d = 0

30 + (n - 1) *(-3) = 0

30 + n*(-3) -1*(-3) = 0

30 - 3n + 3 = 0

      -3n + 33 = 0

               -3n = -33

                   n = -33/-3

n = 11

Where is the Table?

Step-by-step explanation:

The number of students which prefer action-movies to scary movies are 25 students.

To predict how many more students prefer action movies to scary movies, we calculate difference based on proportion of students who prefer action movies from surveyed group and then apply that proportion to total number of students in school,

Number of students who prefer action movies = 14,

Total surveyed students = 40,

Total school students = 200,

Proportion of students who prefer action movies = (Number of students who prefer action movies) / (Total surveyed students),

Proportion of students who prefer action movies = 14/40 = 0.35,

Predicted number of students who prefer action movies in school = Proportion of students who prefer action movies × Total school students

Predicted number of students who prefer action movies = 0.35×200 = 70,

Predicted number of students who prefer scary movies in the school = (Number of students who prefer scary movies) / (Total surveyed students) × Total school students,

Predicted number of students who prefer scary movies = (9/40)×200 = 45

Difference = (Predicted number of students who prefer action movies) - (Predicted number of students who prefer scary movies),

Difference = 70 - 45 = 25,

Therefore, the correct prediction is that 25 more students prefer action movies to scary-movies.

Step-by-step explanation:

Answer:

420 seconds is equal to 7 min

So 7 to 10 or 7 : 10

pls brainliest

These are the steps that you should follow in order to make the necessary calculations to convert 420 Seconds to Minutes. In order to convert from [s] to [min], we have to devide the amount of Seconds by 60.

Then the second step, is to substitute the amount of Seconds with the value of 420 and calculate the division. After successfuly calculating it the result should for 420 Seconds to Minutes should be 7

So 7 to 10 or 7 : 10
