Step-by-step explanation:

chad has 280 baseballs because if miguel has 125 MORE than chad then you have to subtract 125 from 405 to get chads baseball cards

To find out how many baseball cards Chad has, subtract 125 from Miguel's total of 405 baseball cards.

To find out how many baseball cards Chad has, we can use the information given in the question. It is stated that Miguel has 125 more baseball cards than Chad and Miguel has a total of 405 baseball cards. So, to find out how many cards Chad has, we subtract 125 from Miguel's total:

Chad's total = Miguel's total - 125

Chad's total = 405 - 125 = 280 baseball cards

Step-by-step explanation:

Graphically, the x-intercepts of the graph of a quadratic function are its zeroes.

There can be

Looking at the figures, the 2nd graph has no real zeroes, because the graph doesn't cut the x-axis at all!

So, the answer is the second graph.

The graph that represents a quadratic function that has no real zeros is the second graph

For a graph to be a quadratic function, and not have real zeros, then the following must be true

Step-by-step explanation:

The absolute value always returns a positive result, however the expression inside can be positive or negative, that is

4x - 1 = 7 OR 4x - 1 = - 7

4x - 1 = 7 ( add 1 to both sides )

Answer:

A. 7 more than 2 times m

Step-by-step explanation:

If there's a variable (letter) right next to a coefficient (the number) like in this problem, that means that 2 is being multiplied by m.

Since there's a +7 in the problem, that means thats its being added to or "more than."

Multiplication is "times"

7 is not being multiplied by two or m, it's being added.

So, 2m + 7.

Answer:

3,384 miles

Step-by-step explanation:

If can cover 94 miles in 1/6 of an hour.  (1/6 hour)*6 = 1 hour, so multiply 94 by 6 to see how far the plane will travel in 1 hour.  

94(6) = 564 miles in one hour

Multiply that by 6 to see how far the plane travels in 6 hours

564(6) = 3,384  miles

The airplane can cover 3,384 miles in 6 hours.

The formula for finding the distance covered is:

Distance = speed*time

It is given that it can cover 94 miles in 1/6 hours.

This should be converted to per hour.

For this, multiply the distance by 6.

94 miles * 6 = 564 miles

The speed of the plane is 564 miles per hour.

The distance that the plane covers in 6 hours = 564 miles per hour * 6 hours

= 3,384 miles.

Therefore, we have found that the plane can cover 3,384 miles in 6 hours.

Answer:

D

Step-by-step explanation:

given the 2 equations

x + 2y = 27 → (1)

2x + 3y = 46 → (2)

Rearrange (1) expressing x in terms of y by subtracting 2y from both sides

x = 27 - 2y ← substitute into (2)

2(27 - 2y) + 3y = 46

54 - 4y + 3y = 46

54 - y = 46 ( subtract 54 from both sides )

- y = - 8 ( multiply both sides by - 1 )

y = 8 → D

Answer:

D

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - 6 and (a, b) = (- 9, - 3), thus

y - (- 3) = - 6(x - (- 9)), that is

y + 3 = - 6(x + 9)

Final answer:

To find out how much rain a city usually gets, divide the rain it received last year (17 inches) by the percentage of normal rainfall it represented (37%). The city normally receives about 45.95 inches of rain annually.

Explanation:

The student is asking how to calculate the usual annual rainfall for a city if the city received 17 inches of rain last year which was only 37% of their normal rainfall. To find the answer, we want to determine what 100% of their normal rainfall would be. We can use the formula:

Normal Rainfall = (Last Year's Rainfall / Percentage of Normal Rainfall) x 100

Substituting the given values into our formula, we get:

Normal Rainfall = (17 inches / 37%) x 100

Normal Rainfall = (17 / 0.37) inches

Normal Rainfall = 45.95 inches

Therefore, the city usually receives about 45.95 inches of rain annually.

Answer:

right angle triangle.

Step-by-step explanation:

I take it that these are angles and not sides.

x + x + 2x = 180                All triangles have 180 degrees. Combine the left.

4x = 180                            Divide by 4

4x/4 = 180/4                     Do the division

x = 45

Therefore the angles are

x = 45

x = 45

2x = 90

The triangle is a right triangle because it has 1 angle that is 90 degrees.

We split the middle term to obtain:

[tex]( \frac{1}{x - 4)} )( \frac{ - {x}^{2} + 5x + 4x- 20}{x + 2} )[/tex]

We now factor to obtain;

[tex]( \frac{1}{x - 4)} )( \frac{(x - 5)(4 - x)}{x + 2} )[/tex]

Or

[tex]( \frac{1}{x - 4)} ) ( \frac{ - (x - 5)(x - 4)}{x + 2} )[/tex]

We cancel the common factors to get;

[tex]\frac{ - (x - 5)}{x + 2}[/tex]

[tex] = \frac{5 - x}{x + 2}[/tex]

Answer:

(A.) $0.50 per candy bar

(B.) 2 candy bars per dollar

(C.) $6 per dozen

Step-by-step explanation:

The store sells 24 candy bars for $12 . The three unit rate that can be used to describe this sale are

Let us confirm for option A

24 candy bars sale for $12

1 candy bar will sale for ?

cross multiply

12/24 = 1/2 = $0.5

A is right and it is a unit rate

Let us confirm for option B

24 candy bars sale for $12

2  candy bars will sale ?

(2 × 12)/24 = 24/24 = $1

B is right and it is a unit rate

Let us confirm for option C

Note that a dozen is 12 bars

24 candy bars sale for $12

12 candy bars will sale ?

(12 × 12)/24 = 144/24 = $6

C is right and it is a unit rate

Let us confirm for option D

24 candy bars sale for $12

10 candy bars sale for ?

(10 × 12) /24 = 120/24 = $5

Option d is wrong it is not a unit rate. The unit rate here should be 2 candy bar per dollar.
