Answer:

Using the property of intersecting secant:-

$(DE)(CE)=(FE)(LE)$

$(4)(x-1+14)=(5)(x-4+5)$

$4(x+3)=(5x+1)$

$4x+12=5x+5$

$4x+-5x=5-12$

$-x=-7$

$x=7$

$So, CD=x-1=7-1=6$

$so,~your ~answer ~is ~B) ~6$

I played 5 hours of video games over a 3 day weekend, and 60 hours of video games in the month

den301095 [7]

Answer:

The ratios are not equivalent

Step-by-step explanation:

First, in order to find the ratios, we have to change the month to the amount of days.

There are 30 days in April, so we will use this for the ratio.

The ratio for the 3 day weekend is 5:3

The ratio for the month of April is 60:30, which can be simplified to 2:1

So, the ratios are not equivalent, because 5:3 is not equal to 2:1

Three locations are marked next to a river. Points B and C are on the same side of the river, and point A is on the other side o

nlexa [21]

Answer:

74.31353

=74 m

Step-by-step explanation:

given that three locations are marked next to a river. Points B and C are on the same side of the river, and point A is on the other side of the river. To find the distance AB across a river, a distance BC of 241 meters is laid off on one side of the river. It is found that the angle at point B is 108.6° and the angle at point C is 14.9°.

we have information about triangle ABC as side BC =241, Angle B = 108.6 and angle C = 14.9 degrees.

Hence this is an obtuse scalene triangle.

Angle ∠A = 56.5° (III angle)

Using sine formula we get

$\frac{AB}{sin 14.6} =\frac{BC}{sin 56.5} \\AB = 74.31353$

So distance AB is 74 metres.

Tamara makes 12 identical flower arrangements, each with 3 roses and some carnations. She uses a total of 96 flowers.

storchak [24]

Answer:

5 carnations in each arrangement

Total of 60 carnations used

Step-by-step explanation:

First calculate how many flowers are in each arrangement by dividing the total number of flowers by the number of arrangements:

96 ÷ 12 = 8

Given each arrangement has 3 roses, subtract 3 from 8 to find the number of carnations in each arrangement:

8 - 3 = 5

Therefore, there are 5 carnations in each arrangement

Total number of carnations used = 5 x 12 = 60
