Answer:

5:80, there are only 2 numbers

Step-by-step explanation:

The ratio of blue triangles to all triangles is 1 : 17.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

Given that;

A Pattern has 5 blue triangles to every 80 yellow triangles.

Here, Number of blue triangles = 5

Number of all triangles = 5 + 80

                                    = 85

Thus, The ratio of blue triangles to all triangles is,

⇒ Number of blue triangles : Number of all triangles

⇒ 5 : 85

⇒ 1 : 17

Answer:

C) -0.5

Step-by-step explanation:

Since the y₁ is decreasing, that automatically makes it a negative slope, and its decreasing by 0.5, so it's C!

Answer:

Step-by-step explanation:

Using slope formula and solving for y

m = (y2 - y1)/(x2 - x1)

Answer:

y = 2

Step-by-step explanation:

Using slope formula and solving for y

m = (y2 - y1)/(x2 - x1)

-2/7 = (4 - y)/(3 - 10)

-2/7 = (4 - y)/-7

2 = 4 - y

y = 4 - 2

y = 2

A caucluation he can use is adding, just add 7422 and  5570 and you should get your answer.

Step-by-step explanation:

Mario walked total 12992 steps.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Mario walked 7422 steps one day

and, he walks 5570 stops the next day.

So, the total number of steps

= 7422 + 5570

= 12992 steps

Hence, Mario walked total 12992 steps.

Done.... ♥️♥️♥️♥️♥️

The solution of the given inequality v +8 <3 or 8v <-40 is v < -5.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

A mathematical phrase in which the sides are not equal is referred to as being unequal.

Given the inequality,

v +8 < 3

Adding -8 on both sides

v + 8 - 8 < 3 - 8

v < -5

Or,

8v <-40

Divide 8 on both side

v < -5

Hence "The solution of the given inequality v +8 <3 or 8v <-40 is v < -5".

12+8.3(g)=p

Step-by-step explanation:

#of gal of water x 8.3 per gal. number of gallons of water is not given so it is represented by g

+ weight of pail which is given, 12

= p , weight of full pail

b = 92 degrees (choice B)

c = 92 degrees (choice D)

d = 92 degrees (choice F)

================================================

Explanation:

Angles a and b are supplementary because they form a straight angle when combined. The two angles add to 180

a+b = 180

88+b = 180 ... plug in a = 88

b = 180-88 ... subtract 88 from both sides

b = 92

------------

Angles b and c are congruent because they are alternate interior angles. Alternate interior angles are congruent when dealing with parallel lines.

Since the diagonal entrance ramps are parallel, this means the corresponding angles c and d are congruent.

Since b = 92, this means c = 92 and d = 92 also.

Answer:

D. 48

Step-by-step explanation:

y=10x-2 is our equation

If x is 5, then multiply 10 by 5. You get 50.

Subtract 2 from that. You get 48.

Answer:

D, 48

Step-by-step explanation:

Given x=5, plug x into y=10x-2

First you should plug the given x into the x in the equation. And put () around it.

y=10(5)-2

Now you multiply 10 by 5 and you get 50.

y=50-2

Now the last step is to subtract 2 from 50 which you will end up getting y=48. So the answer is y=48 which is letter D.
