Answer: 12.25

Step-by-step explanation:

Given the following details :

DAC = 90° and ABC = 90° = right angled

Segment AB is Parallel to segment DC

FROM THE DETAILS ;

Triangle ABC and ACD are similar triangles.

Length AC = 7 Units

Length AB = 4 Units

For similar triangles :

Segment CD /AC = Segment AC / AB

CD / 7 = 7 / 4

Cross multiply

CD × 4 = 7 × 7

CD × 4 = 49

CD = 49 / 4

CD = 12.25 Units

In a group of 60 students, 12 students take Algebra I, 18 students take Algebra II, and 8 students take both subjects. How many
vodomira [7]
Since 8 students take both, that leaves only 4 students who take Algebra I alone.
Likewise since 8 students take both, that leaves 10 who only take Algebra 2
So out of the 60, twenty two are taking either Alg I Alg Ii or both.

That leaves 38 people who are not taking either.
b. 38

You can set this up using a 2 circle venn diagram.  Just be sure to put the 8 who take both in first.

wariber [46]

Answer:

T = 4B + 10C

Step-by-step explanation:

Since there are 4 doughnuts in a bag then there are 4B doughnuts in B bags

Since there are 10 doughnuts in a carton then there are 10C doughnuts in C cartons, thus summing the two quantities gives

T = 4B + 10C

The amount of $15,000 is invested in two funds paying 2% and 5% simple interest. If the annual interest is $540, how much of the
Lostsunrise [7]

Answer:

The amount $15000 is divided as

in 2% = $7000

in 5% = $8000

Step-by-step explanation:

It is given that the total amount is $15000 and rates of interests are 2% and 5%.

<em>Let the amount invested in 2% be "x", so the amount invested in 5% is (15000 - x).</em>

The annual interest on x part is given as,

= (\frac{2}{100})(x)

Similarly, The annual interest on (15000 - x) part is given as,

=  (\frac{5}{100})(15000 - x)

the total annual interest is given as $540

Thus, <em>540 = (\frac{5}{100})(15000 - x) + (\frac{2}{100})(x)</em>

<em>54000 = 2(x) + 75000 - 5(x)</em>

<em>21000 = 3(x)</em>

x = \frac{21000}{3} = 7000

Thus the shares are $7000 and (15000 - 7000) $8000 .
