Answer:

The probability that a student taking only math will get picked is approximately 29%

Step-by-step explanation: This is because out of the total number of students taking math (95), 52 of such students are also taking science. In order to get the number of students only taking math you have to do 95-52=43 and to put that against the amount of total students the ratio would be 43:147 or 42/147 and if you plug 42/147 into a calculator you will recieve a long decimal that you can then round to 29%.

Answer:

DA = 25

Step-by-step explanation:

Given that,

→ ABC = ADC ==> (1)

→ BA = 25 ==> (2)

From the given (1) and (2),

→ BA = DA

→ BA = 25

→ [ DA = 25 ]

Hence, the answer is 25.

Answer:

A. $x^2 = (4x - 1)^2 + (6x + 7)^2$

Step-by-step explanation:

The question seems to be incomplete. However, we'll make the following assumption.

$Opposite = 6x + 7$

$Adjacent = 4x - 1$

$Hypothenuse = x$

Pythagoras theorem states that:

$Hypothenuse^2 = Opposite^2 + Adjacent^2$

Substitute values for Hypothenuse, Opposite and Adjacent.

This gives

$x^2 = (6x + 7)^2 + (4x - 1)^2$

$x^2 = (4x - 1)^2 + (6x + 7)^2$

From the list of given options.

Consider the system of equations.

vredina [299]

1. c (multiply by 3 to get 9x - 3y = 15)
2. c (add the new top expression with the bottom one to get 11x = 0) substitute 0 into either equation to get -5)

hope this helps!
