Answer:

y - 7 = - [tex]\frac{5}{2}[/tex] (x + 2)

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 = - [tex]\frac{5}{2}[/tex] and (a, b ) = (- 2, 7 ) , then

y - 7 = - [tex]\frac{5}{2}[/tex] (x - (- 2) ) , that is

y - 7 = - [tex]\frac{5}{2}[/tex] (x + 2)

Answer:

5/11 or 45 percent, since there are 5 blue cards

The probability that Isabella will take a blue card is 5/11.

Probability is the chance that something will happen, or how likely it is that an event will occur.

P(E) = total number of favorable outcomes/ total number of outcomes

Where,

P(E) is the probability of any event.

According to the given question

Five blue cards, two green cards and four red cards.

⇒ total number of outcomes =  5+ 2 + 4 = 11

For finding the probability of blue card

Total number of blue cards is 5.

⇒ total number of favorable outcomes = 5

Therefore,

The probability of getting blue card

= number of favorable outcomes/ total number of outcome

= [tex]\frac{5}{11}[/tex]

Hence, the probability that Isabella will take a blue card is 5/11.

Answer:

3 cups flour

Step-by-step explanation:

set up a proportion and cross-multiply:

1/4 = 1/2

3/2      f

1/4f = 3/4

4f = 12

f = 3

Answer:

3 cups

Step-by-step explanation

basically if 1/4 cup of milk is for 1 1/2 cups of flour ------ 1/2 cup is twice the amount that a quarter cup is because a 1/4 cup + a 1/4 cup = 1/2 cup so you double the amount of flour too and 1 1/2 + 1 1/2 is 3 cups of flour.

1/4 + 1/4 = 1/2 (milk)

1 1/2 + 1/12 = 3 (flour)

Answer:90

Step-by-step explanation:

The distance between these cities on the map is 90 mm.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Cincinnati is about 225 miles from Cleveland and on scale 10 millimetres is equal to 25 miles.

The distance on the map will be calculated as,

25 miles = 10 mm

1 mile = 10 / 25 mm

225 miles = ( 225 x 10 ) / 25

225 miles = 90 mm

Therefore, the distance between these cities on the map is 90 mm.

Answer: 30 seconds

Step-by-step explanation:

From the question, we are informed that one string flashes every 10 seconds while the other one string flashes every 15 seconds.

The number of minutes that it'll take before they both flash again at the same time will be gotten by calculating the LCM of 10 and 15. This will be:

10 = 10, 20, 30, 40, 50 ...

15 = 15, 30, 45, 60, 75 ....

We can see that the lowest common multiple of 10 and 15 is 30. Therefore, the answer is 30.

They'll both flash again at same time in 30 seconds.
