24/3 = 8

5 x 8 = a

5 x 8 = 40

a = 40

hope this helps

QUESTION : $\frac{3}{5}$ = $\frac{24}{a}$ . What I would do is divide 24 by 3, and once you do that, your answer is 8. So that leads you to the conclusion that 8 is multiplied by 3 to get 24. Move down to the 5 and the a. If the numerator of the first fraction is multiplied by 8 to get the numerator of the second fraction, then you can sure as heck believe that the same applies to both denominators.

So I would say you multiply 5 with 8. 5 × 8 is 40, and so a = 40.

A triangle has vertices at f (-7,3),g(2,6) and h(3,5)

Allisa [31]

Answer:

F(-7,3) -> F'(-7,-3)

G(2,6) -> G'(2,-6)

H(3,5) ->H'(3,-5)

Step-by-step explanation:

If you are taking point (a,b) and reflecting it across the x-axis (the horizontal axis), your x value is going to stay the same because you want the point on the same vertical line as (a,b). The y-coordinate is going to be opposite because you want a reflection and the opposite of b will this give you the same distance from the x-axis as b.

So the transformation is this: (a,b) -> (a,-b).

All this means is leave x the same and take the opposite of y.

F(-7,3) -> F'(-7,-3)

G(2,6) -> G'(2,-6)

H(3,5) ->H'(3,-5)

Given: Q=7m + 3n, R= 11 - 2m, S= n + 5, and T= -m - 3n + 8 <br><br><br> simplify R - [S + T]

Soloha48 [4]

R = 11-2m
S = n+5
T = -m-3n+8
---------------------------
Add up S and T to get...
S+T = (n+5)+(-m-3n+8)
S+T = n+5-m-3n+8
S+T = -m+(n-3n)+(5+8)
S+T = -m+(1n-3n)+(5+8)
S+T = -m+(-2n)+(13)
S+T = -m-2n+13
---------------------------
Subtract that result from R
R - [S + T]
11-2m - [-m-2n+13]
11-2m +m+2n-13
(-2m+m) + (2n) + (11-13)
(-2m+1m) + (2n) + (11-13)
(-1m) + (2n) + (-2)
-m + 2n - 2
---------------------------
---------------------------
The final answer is -m + 2n - 2

All the fourth-graders in a certain elementary school took a standardized test. A total of 81% of the students were found to be

Dvinal [7]

Answer:

The probability that a student is proficient in mathematics, but not in reading is, 0.10.

The probability that a student is proficient in reading, but not in mathematics is, 0.17

Step-by-step explanation:

Let's define the events:

L: The student is proficient in reading

M: The student is proficient in math

The probabilities are given by:

$P (L) = 0.81\\P (M) = 0.74\\P (L\bigcap M) = 0.64$

$P (M\bigcap L^c) = P (M) - P (M\bigcap L) = 0.74 - 0.64 = 0.1\\P (M^c\bigcap L) = P (L) - P (M\bigcap L) = 0.81 - 0.64 = 0.17$

The probability that a student is proficient in mathematics, but not in reading is, 0.10.

The probability that a student is proficient in reading, but not in mathematics is, 0.17

A triangle has three sides: a, b, and c. Side a = 72 feet, and side b = 154 feet, and side c = 170 feet. True or false: this tri

Juliette [100K]

Answer:

True

Step-by-step explanation:

If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²

c is the largest side and a and b are the two smaller sides of the triangle.

So if this is true then √72² + 154² should be 170:

170² = 72² + 154²

28900 = 5184 + 23716

28900 = 28900

So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
