Last year Stevie was 281/4 inches tall. Since then he has grown 51/5
inches. How tall is Stevie now? Simplify your answer.
T
Answer:
80.45 inches
Step-by-step explanation:
Last year Stevie was 281/4 inches tall, which is: 70.25 inches (70 1/4)
He has grown 51/5 inches which is: 10.2 inches (10 1/5)
70.25 inches (last years height) + 10.2 inches (how many he has grown) = 80.45 inches
Stevie is 80.45 inches tall now.

Answer:
-8n² - 8n + 3
Step-by-step explanation:
Combine like terms (terms with the same variables, as well as the same amount of that variable).
(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)
First, distribute the negative sign to all terms within the second parenthesis:
4n⁴ - 8n + 4 - 8n² - 4n⁴ - 1
Combine like terms:
(4n⁴ - 4n⁴) - 8n² - 8n + (4 - 1)
-8n² - 8n + 3
-8n² - 8n + 3 is your answer.

Answer:
z = 9
Step-by-step explanation:
JH is a perpendicular bisector of Δ IJK.
Thus the triangle is isosceles with
JK = JI , that is
7z = z + 54 ( subtract z from both sides )
6z = 54 ( divide both sides by 6 )
z = 9
3. For each equation, determine if x=2 is a solution. Explain or show your reasoning. Select ALL of those where the x can equal 2. 2 points -2(x - 4) = 4 26/x = 13 - 3.8x = -7.4 4(x - 1) - 3(x - 2) = -8
Answer:
26/x = 13
x = 2
Step-by-step explanation:
2(x - 4) = 4
2x - 8 = 4
2x = 4 + 8
2x = 12
x = 12/2
x = 6
26/x = 13
Cross product
26 = x * 13
26 = 13x
x = 26/13
x = 2
- 3.8x = -7.4
x = -7.4 / -3.8
x = 1.95
4(x - 1) - 3(x - 2) = -8
4x - 4 - 3x + 6 = -8
x + 2 = -8
x = -8 - 2
x = -10

Mila buys a two liter soda bottle. She accidentally drops the soda bottle and spills 287 milliliters of soda. How much soda is left?
Answer:
1713 milliliters
Step-by-step explanation:
1 liter is 1000 milliliters, so 2 liters is equal to 2000 milliliters.
2000 mL - 287 mL = 1713 mL
So 1713 mL are left.

Notice that v points into the third quadrant since both of its components are negative. If you want a vector to point in the same direction, it would need to have the same sign on its components. So C is the correct choice.
The factor of 1/√80 comes from normalizing the vector v. Its norm/magnitude is
|v| = √((-4)² + (-8)²) = √(16 + 64) = √80
so the unit vector that points in the same direction as v is simply v / |v|.
Based on the data, how many of 650 ice cream eaters would be expected to prefer vanilla or cookie dough ice cream flavor Number of people vanilla 71 strawberry 22 cookie dough 27 chocolate 83
Answer: 305 people
Step-by-step explanation:
The total number of people sampled is:
= 71 + 22 + 27 + 83
= 209
Out of this 209, the number of people who prefer Vanilla and cookie dough ice cream is:
= 71 + 27
= 98 people
In a sample of 209 people, 98 people would prefer either vanilla or cookie dough. In 650 people, that number would therefore be:
= 98/ 209 * 650
= 305 people

In 2014, the population is of the United States was about 318,900,000 people. Choose the best approximation of the United States Population in 2014.
people
people
Answer:
people
Step-by-step explanation:
Given
US Population in 2014: About 318,900,000
Required
Approximate
From the given options, it's seen that the population of US is to be approximated to one significant digit and the result should be presented in standard form
So, the first step is to write out the population
318,900,000
As a general rule,
Category 1: Digit 0-4 are approximated to 0
Category 2: Digit 5-9 are approximated to 1
Since, we are approximating to one significant digit, only the first digit is needed, others are to be approximated.
The first digit is 3, meaning that approximation starts from the next digit which is 1
Approximating 318,900,000 will give 300,000,000 because "1" falls in category 1 as illustrated above.
The final step is to convert 300,000,000 to standard form.
There are 8 0s after 3.
Hence,
Conclusively, the approximation of 318,900,000 is people

4x - 1 = -13 show the work please
Answer:
x = -3
Step-by-step explanation:
4x - 1 = -13
add 1 to each side
4x = -12
x = -3
Answer:
x = -3
Step-by-step explanation:
Add 1 to both sides to, this gives you 4x = -12. then divide both sides by 4, which would give you x = -3.

Step-by-step explanation:
A ball is thrown into the air. The height h, in feet, of the ball after x seconds is given by the function h = −16(x − 2)2 + 72. What is the equation in standard form and the maximum height of the ball?
A. h(x) = −16x2 + 32x + 72; 72 ft
B. h(x) = −16x2 − 32x + 72; 32 ft
C. h(x) = −16x2 − 64x + 32; 32 ft
D. h(x) = −16x2 + 64x + 8; 72 ft
Answer:
Step-by-step explanation:
h = −16(x − 2)² + 72
= −16((x − 2)(x − 2)) + 72 expand the square (x - 2)² = (x - 2)(x - x)
= -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72
= -16 (x² + (-2x) + (-2x) + (4) ) + 72
= -16 (x² + (-4x) + (4) ) + 72
= -16 (x² - 4x + 4 ) + 72
= (-16)(x²) + (-16)(-4x) +(-16)(4) + 72
= -16x² + 64x - 64 + 72
= -16x² + 64x + 8 My guess is D ; 72 ???
I have no clue what the ; 72 means after the given answer. It must be a standard form thing I never learned.
The equation in standard form -16x² + 64x + 8 and the maximum height of the ball is 72 feet.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
The height h, in feet, of the ball after x seconds is given by the function
h = −16(x − 2)² + 72
Now, simplifying the above expression is
h = −16((x − 2)(x − 2)) + 72
h = -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72
h = -16 (x² + (-2x) + (-2x) + (4) ) + 72
h = -16 (x² + (-4x) + (4) ) + 72
h = -16 (x² - 4x + 4 ) + 72
h = (-16)(x²) + (-16)(-4x) +(-16)(4) + 72
h = -16x² + 64x - 64 + 72
h = -16x² + 64x + 8
and, the maximum height is 72 feet.

A square has a perimeter of 76 cm. Each side measures x + 3.
What is the value of x, in centimeters?
The value of given x is 16
Given that:
Perimeter of square = 76 cm
Side of square = (x + 3)
Find:
The value of x
Computation:
Perimeter of square = 4[Side]
76 = 4[x + 3]
76 = 4x + 12
4x = 76 - 12
