Omar is planning to buy some new baseball shoes. He has already saved $22.50 The shoes cost at least $38 dollars. He writes an inequality to determine how much more he will need to save

Answers

Answer:

At least $15.50

Step-by-step explanation:

Omar is planning to buy some new baseball shoes. He has already saved $22.50

The shoes cost at least 38 dollars.

At least means, greater than or equal to which is represented by the sign

The inequality is given as

22.50 + x ≥ 38

x ≥ 38 - 22.50

x ≥ 15.5

Therefore, he would need to save at least $15.50

Answer:

(x+4)(x+5)

Step-by-step explanation:

Let's factor x2+9x+20

x2+9x+20

The middle number is 9 and the last number is 20.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Addd together to get 9

multiply together to get 20

Can you think of the two numbers? hmmmmmm :D

Try 4 and 5:

4+5 = 9

4*5 = 20

Fill in the blanks in

(x+_)(x+_)

with 4 and 5 to g.et...

(x+4)(x+5)

Hope this helps :D

Mark wants to round to the nearest hundred to estimate the sum of 271 and 582.
He wrote 270 + 580 = 850.

Part A
What mistake did Mark make?
A.
00:00



Mark should have rounded 271 to 250 and rounded 582 to 550: 250 + 550 = 800.
B.
00:00



Mark should have rounded 271 to 250 and rounded 582 to 600: 250 + 600 = 850.
C.
00:00



Mark should have rounded 271 to 300 and rounded 582 to 500: 300 + 500 = 800.
D.
00:00



Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 600 = 900.
00:00

Part B
What is the sum of 271 and 582 rounded to the nearest hundred?
A. 300
B. 850
C. 900
D. 1,000

Answers

Answer:

Step-by-step explanation:

Part A:

Mark did not round to the nearest hundreds, he rounded to the nearest tens.

Option A (Incorrect):

271 and 582 are normally not rounded down, unless we are using limits coming from the left and a unique equation.

Option B (Incorrect):

271 as the same problem as option A, but 582 rounding to 600 is correct. It doesn't make sense to round both numbers differently, unless stated.

Option C (Incorrect):

271 rounding to 300 is correct, but 582 is not normally rounded down to 500 unless we are using limits coming from the left and a unique equation. Unless stated, don't round both numbers differently.

Option D (Correct):

271 rounded to 300 and 582 rounded to 600 looks correct for rounding to the hundreds.

Part B:

There are two ways to solve this question:

One way:

271 + 582 = 853

Round 853 to the nearest hundred for 900

(Note: Round 853 to the nearest tens for 850.)

Second way:

271 + 582

Round Numbers:

300 + 600

= 900

What is the green dashed line called?

Answers

Answer:

The line (or "axis") of symmetry is the y-axis, also known as the line x = 0. This line is marked green in the picture. The graph is said to be "symmetric about the y-axis", and this line of symmetry is also called the "axis of symmetry" for the parabola.

The equation of the function g(x), after the translation, is given as follows: g(x) = (x + 2)² + 4.

What is a translation?

A translation happens when either a figure or a function are moved horizontally or vertically.

The four translation rules for functions are given as follows:

Left a units: f(x + a).

Right a units: f(x - a).

Up a units: f(x) + a.

Down a units: f(x) - a.

The parent function for this problem is given as follows:

f(x) = x².

For this problem, the parent function was moved:

2 units left, hence g(x) = f(x + 2).

4 units up, hence g(x) = f(x + 2) + 4.

Hence the function g(x) is defined as follows:

g(x) = (x + 2)² + 4.

Which ratio is smaller, 32 : 24 or 30 : 22?​

Answers

Answer:

32 : 24 is smaller

Step-by-step explanation:

32 : 24 = 32/56, reduced is 4/7

30 : 22 = 30/52, reduced is 15/26

a common denominator is 182:

4/7 = 104/182

15/26 = 105/182

32:24 -> 30:22

You need to get one number from each ratio to be equal

I’m gonna get 32 and 30 to equal

*first divide both ratios by 2(don’t have to do this just makes the no.’s smaller)
32:24
16:12

30:22
15:11

Multiply 16:12 by 15
And multiply 15:11 by 16

32:24 -> 16:12 -> 240:180
30:22 -> 15:11 -> 240:176

176<180
Therefore ratio 30:22 is smaller

Which statement is true about the equation in the box?
x + 9 - 4x = -3x - 3

A. There is only 1 solution, and x = -3.
B. There is only 1 solution, and x = 9.
C. There are infinitely many solutions because the variables cancel each other.
D. There is no solution because 9 ≠ -3.

Answers

Answer:

D. There is no solution because 9 ≠ -3.

Step-by-step explanation:

For finding out the statement let's check it ourselves

x + 9 - 4x = - 3x - 3

-3x + 9 = - 3x - 3

9 ≠ - 3

So there is no solution for the equation.

Which linear function is graphed on the grid?
a - g(x) = 2/15x - 6
b - g(x) = 2/15x + 45
c - g(x) = 15/2x - 6
d - g(x) = 15/2x + 45

Answers

Answer:

G(x)=2/15x-6

Step-by-step explanation:

The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

x/a + y/b = 1

Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.

From the graph, the x-intercept is - 6, and the y-intercept is 45. Then the equation is given as,

x/(-6) + y/45 = 1

- 15x + 2y = 90

y = (15/2) x + 45

g(x) = (15/2) x + 45

The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

Answers

Answer:

a. Velocidad = 16 m/s

b. Deceleración = 0.64 m/s²

Step-by-step explanation:

Dados los siguientes datos;

Tiempo = 25 segundos

Distancia = 400 metros.

a. Para encontrar la velocidad;

Velocidad = distancia/tiempo

Velocidad = 400/25

Velocidad = 16 m/s

b. Para encontrar la desaceleración;

Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.

Deceleración = (v - u)/t

Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.

Deceleración = (0-16)/25

Deceleración = 16/25

Deceleración = 0.64 m/s²
