Did Fatimah throw the javelin the furthest?
You must show your working.

Yes or no

Answers

Answer:

Hi,

Step-by-step explanation:

sum of all distances=16.04*5=80.2

sum of the four distances=15.2+15.9+16.8+16.1=64

Fatimah 's distance=80.2-64=16.2

Fatimah throw the javelin not the furthest.

Amelia has a triangular kite with an area of 30 square inches and a height of 6 inches. How long is the base of the kite?

Answers

Area of triangle = 0.5 * base * height
30 = 0.5 * 6 * base
30 = 3 * base
so , base = 10 inch

Answer:

Draw a vertical line to break the kite into two equal triangles with a base of 36 and a height of 15. Use the formula A = 1

bh to find the area of each. The sum of the areas is the area of the kite.

What is the solution of log3x − 5 16 = 2?

the base is 3x - 5, and the argument is 16

Answers

Answer:

x=3

Step-by-step explanation:

The given equation is $\log_(3x-5)16=2$

The relation between logarithmic function and exponential function is given by

$\text{If }y=b^x\text{ then }x=\log_b(y)$

On comparing, we get

b = 3x-5

y = 16

x = 2

Hence, using the relation, we have

$16=(3x-5)^2$

Take square root both sides

$\pm√(16)=3x-5$

On simplifying

$3x-5=\pm4\n\n3x=\pm4+5\n\nx=(1)/(3)(5\pm4)\n\nx=(1)/(3)*1,(1)/(3)*9\n\nx=(1)/(3),3$

For x = 1/3

$3x-5\n\n=3\cdot (1)/(3)-5\n\n=-4$

Base cannot be negative.

Hence, the value of x is 3

Hello,

log (16)=2 in base 3x-5
==>16=2^(3x-5)
==>2^4=2^(3x-5)
==>4=3x-5
==>3x=9
==>x=3

4(4x + 3) + 6(2 - x) - 3(2x - 1) = 19

Answers

your answer is -2.
4(4x+3)+6(2-x)-3(2x-1)=19
4*4x=16x
4*3=12
6*2=12 and 6*x=6x
-3*2x=-6 and -3*-1=-3. then collect
like term. is long just cant type it but that is your answer

4(4x + 3) + 6(2 - x) - 3(2x - 1) = 19 the answer would be -2
