Let
x----------> number total of pictures

we know that
A------>25
B------> 4%----> 4/100------> 0.04x
C-----> 0.29------> 29%-------------------> 0.29x
D------> 27/100 --------> 27%--------------> 0.27x

[B+C+D]=4%+29%+27%--------> 60%
that means A=100%-60%---------> 40%
so
A-------------> 0.40x
A------>0.40 xB------> 0.04xC-----> 0.29xD------> 0.27x

the answer is
the photographers list in order from least to greatest by the amount of pictures they take is
B------> 0.04x
D------> 0.27x
C------> 0.29x
A------> 0.40x

If BC = 6 and AD = 5, find DC. 4 4.5 7.2
anygoal [31]

Answer:

The length of CD is 4 units

Step-by-step explanation:

Given the triangle ABC and if BC = 6 units and AD = 5 units

we have to find the length of DC.

In ΔABC and ΔBDC

∠ABC=∠BDC    (each 90°)

BC=BC   (common)

∠C=∠C   (Common)

By ASA rule, ΔABC≈ΔBDC

Therefore their corresponding sides are in proportion

\frac{BC}{AC}=\frac{BD}{AB}=\frac{CD}{BC}

\frac{BC}{AC}=\frac{CD}{BC}

Let CD=x units

BC^2=(AC)(CD)

6^2=(AD+CD)CD

36=(5+x)x

36=5x+x^2

x^2+5x-36=0

x^2+9x-4x-36=0

x(x+9)-4(x+9)=0

(x-4)(x+9)=0

x=4, -9

Distance can't be negative therefore

The length of CD is 4 units

Leo buys a new car for $17,600. The simple interest rate is 8.4% and the amount of loan (plus simple interest) is repayable in 5
Dmitrij [34]

Answer:

$24,992

Step-by-step explanation:

The equation for simple interest is I = PRT where I is the interest earned, P is the principal deposited/borrowed, R is the rate as a decimal, and T is time in years.

I = (17,600)(0.084)(5)

I = 7,392

The total amount that must be repaid is the interest + the principal:

7,392 + 17,600 = 24,992
