Answer: 12.5%
Step-by-step explanation:
2=x•16
x= 0.125
Turn it into a decimal
X= 12.5%
Base times hight divided by 2
(12.6 x 9.4)/2
Answer:
a. Narrower
b. Shifts left
c. Opens up
d. Shifts up
Step-by-step explanation:
The original quadratic equation is y = x²
The given quadratic equation is y = 5·(x + 4)² + 7
The given quadratic equation is of the form, f(x) = a·(x - h)² + k
a. A quadratic equation is narrower than the standard form when the coefficient is larger than the coefficient in the original equation
The quadratic coefficient is 5 > 1 in the original, therefore, the quadratic equation is <em>narrower</em>
b. Given that the given quadratic equation has positive 'a', and 'b', and h = -4, therefore, the axis of symmetry <em>shifts left</em>
c. The quadratic coefficient is positive, (a = 5), therefore, the quadratic equation <em>opens down</em>
d. The value of 'k' gives the vertical shift, therefore, the given quadratic equation with k = 7, <em>shifts up.</em>
Answer:
4 tiles
Step-by-step explanation:
If the width is 84 cm, let's take a 84cm lengthed tile.
in the remaining part we get 112-84=28 cm
let's check whether 84÷ 28 is a whole number. if it's a whole number we can keep the n number of 28 cm length tile
84÷28=3
luckily we dont need to think a lot. just put 3, 28 cm tile in the balance part .
she only needs 4 tiles to fill the table
Answer:
If your saying estimate this number in a decimal without calculators I think I might be able to help as illustrated below:
Step-by-step explanation:
2 5/6 shows that the whole number will be a 2. The 5/6 is a decimal below one as it is not one whole fraction. This means that we have to estimate the value of 5/6 and add that value to the number 2. 1/3 is a common fraction that is equal to about 0.33. This is because 0.33 + 0.33 + 0.33 is almost 1, which means 1/3 of one is indeed equal to 0.33.
<u>This means we divide 0.33 by 2, because that would be equal to (1/3)/(2), or 1/6. </u>0.33/2 seems like it would be 16.5. 16.5 * 5, as in 5/6, would be 82.5.
I would then say that the estimate of 2 5/6 is 2.83.
