Answer:

Marie did not walk  \dfrac{5}{2} hours more, but she walk \dfrac{9}{8} hours more .

Step-by-step explanation:

Given as :

The normal hours did Maria walks each day = \dfrac{3}{4} hours

The hours did Maris walk today = \dfrac{5}{2} times normal hours walk

Or, The hours did Maris walk today = \dfrac{5}{2} ×  \dfrac{3}{4} hours

Or, The hours did Maris walk today = \dfrac{5\times 3}{2\times 4} hours

Or, The hours did Maris walk today =  \dfrac{15}{8} hours

Now, Let The difference between normal hours walk and today hours walk = x hours

So, x = \dfrac{15}{8} hours -  \dfrac{3}{4} hours

<u>Taking LCM</u>

Or, x = \dfrac{15 - 6}{8} hours

Or, x =  \dfrac{9}{8} hours

So, Maria walk \dfrac{9}{8} hours more

Hence, Marie did not walk  \dfrac{5}{2} hours more, but she walk \dfrac{9}{8} hours more . Answer

The following graphs have a scale assigned to them: The area of each grid
dezoksy [38]

The graphs that are density curves for a continuous random variable are: Graph A, C, D and E.

<h3>How to determine the density curves?</h3>

In Geometry, the area of the density curves for a continuous random variable must always be equal to one (1). Thus, we would test this rule in each of the curves:

Area A = (1 × 5 + 1 × 3 + 1 × 2) × 0.1

Area A = 10 × 0.1

Area A = 1 sq. units (True).

For curve B, we have:

Area B = (3 × 3) × 0.1

Area B = 9 × 0.1

Area B = 0.9 sq. units (False).

For curve C, we have:

Area C = (3 × 4 - 2 × 1) × 0.1

Area C = 10 × 0.1

Area C = 1 sq. units (False).

For curve D, we have:

Area D = (1 × 4 + 1 × 3 + 1 × 2 + 1 × 1) × 0.1

Area D = 10 × 0.1

Area D = 1 sq. units (True).

For curve E, we have:

Area E = (1/2 × 4 × 5) × 0.1

Area E = 10 × 0.1

Area E = 1 sq. units (True).

Jessica reads a story about a turtle that swam 16 feet in 24 seconds. She assumes that the time, t, that it takes the turtle to
Monica [59]
You would start by figuring out the distance the turtle swims every second by dividing 24 by 16.
24➗16=1.5
From this we can take the numbers from either T: 1, ___, 24, 45 or D: ___, 10, 16, ___ to figure out the blank spaces for the other using multiplication or division. Divide T by 1.5, or multiply D by 1.5 to find the other

T: 1, 15, 24, 45
D: 1.5, 10, 16, 30

Which piece of additional information can be used to prove △CEA ~ △CDB?
8_murik_8 [283]
<h3>Answer:</h3>

∠BDC and ∠AED are right angles

<h3>Step-by-step explanation:</h3>

Because ∠C ≅ ∠C, the additional bit of information above can be used to show AA similarity.

____

None of the other offered choices says anything about <em>both</em> triangles. In order to show similarity, you need information about corresponding parts of the <em>two</em> triangles. Information about one triangle alone is not sufficient.
