Answer:

mean = 52

Step-by-step explanation:

Just add all four together and divide by 4. That's the mean.

Sum (49 + 43 + 53 + 63) = 208

Mean = 208 /4 = 52

The base of an isosceles triangle is one and a half times the length of the other two sides.A smaller triangle has a perimeter t

Anna11 [10]

Answer:

Perimeter of the smaller triangle = 1.75x

Step-by-step explanation:

Let the two equal sides of an isosceles triangle = x

Therefore, length of the base = $(1\frac{1}{2})x$

Perimeter of this isosceles triangle = x + x + $(1\frac{1}{2})x$

= 2x + $(1+\frac{1}{2})x$

= 2x + x + $\frac{x}{2}$

= $\frac{5x}{2}$

Since, smaller triangle has a perimeter that is half the perimeter of the larger triangle,

Length of each corresponding side of smaller triangle will be half of the larger triangle.

Length of sides of the smaller triangle = $\frac{x}{2},\frac{x}{2},(1\frac{1}{2})\frac{x}{2}$

Perimeter of the smaller triangle = $\frac{x}{2}+\frac{x}{2}+(1\frac{1}{2})\frac{x}{2}$

= x + $\frac{x}{2}+\frac{x}{4}$

= $\frac{3}{2}x+\frac{x}{4}$

= $\frac{6}{4}x+\frac{x}{4}$

= $\frac{7}{4}x$

= 1.75x

Therefore, expression that represents the perimeter of the smaller triangle is (1.75x)

The height, h, in feet, of an object dropped from the top of the Empire State Building can be estimated using the equation h= -1

Ksju [112]

To determine the height of the object after a certain time it is dropped, we simply substitute the time to the function given. We calculate as follows:

h = -16t^2 + 1454
h = -16(8^2) + 1454
h = 430 feet above the ground

Hope this answers the question. Have a nice day.

Noah has $50. He wants to buy a cell phone case for $20 and some accessories. Each accessory costs $8. How many accessories (x)

levacccp [35]

Answer:

Noah can buy 2 accessories.

Step-by-step explanation:

Given:

Money Noah has = $50

Cost of Cell phone case = $20

Cost of each accessory =$8

Amount he wants to be left = $8

So Total Amount he he wants to spend on accessories and Cell phone case will be equal to Money Noah has minus Amount he wants to be left.

framing in equation form we get;

Total Amount he he wants to spend on accessories and Cell phone case = $\$50-\$8 =\$42$

No we need to find the number of accessories Noah can buy.

Let the number of accessories be 'x'.

Now we can say that;

Cost of Cell phone case plus Cost of each accessory multiplied by number of accessories should be less than or equal to Total Amount he he wants to spend on accessories and Cell phone case.

framing in equation form we get;

$20+8x\leq 42$

Subtracting both side by 20 we get using Subtraction property of Inequality.

$20+8x-20\leq 42-20\\\\8x\leq 22$

Now Dividing both side by 8 using Division property of Inequality we get;

$\frac{8x}{8}\leq \frac{22}{8}\\\\x\leq 2.75$

Now rounding to whole number we get ;

$x\leq 2$

Hence Noah can buy 2 accessories.
