A = 84 + 2t.

Assuming A has the same value, the given equations form a system of two linear equations. Solve this system using an algebraic approach and interpret your answer.

Answer:

1/100

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

the probability = (number of yellow marbles / total number of marbles) x (number of yellow marbles / total number of marbles)

total number of marbles = 1 + 5 + 4 = 10

(1/10) x (1 / 10) = 1 /100

Answer:

The radius of the cylinder is approximately 28 feet.

Step-by-step explanation:

Volume of a cylinder = πr^2 h

⇝ 25,456 = π r^2 10

⇝r^2 = 25456 *7 / 22*10

⇝r^2 = 178192/220

⇝r = √809.9636

⇝r = 28.45 ft

Answer:

Answer:

k = 42

Step-by-step explanation:

This is a complementary angle, meaning that the angles formed equal 90 degrees. We know it is complementary because the angle is shown was a tiny square, a sign that it is 90 degrees. Thus, the two angles (k+1) and 47 added together must equal 90. So, we can write an equation:

(k+1) + 47 = 90

k + 1 = 43

k = 42.

Step-by-step explanation:

Answer:

x = 3, y = 5

Step-by-step explanation:

Since the ordered pairs are equal, then equate the x and y coordinates

x + 2 = 5 ( subtract 2 from both sides )

x = 3

y - 1 = 4 ( add 1 to both sides )

y = 5

Answer:

B. (0, 4)

Step-by-step explanation:

so we need to find the value of m and n, and luckily we have 2 equations that'll help. (I'm going to use the substitution method for this instead of the Elimination method because I am lazy)

first we need to solve for m, but we already have an equation that tells us what m is equal to, m = n - 4.

now we just need to plug in our new m into the other equation and solve for n. (we are using m + 5n = 20 for that)

so now we get

(n - 4) + 5n = 20

so we solve for n

n + 5n = 24

6n = 24

n = 4

now that we know that n is 4, we can plug that into our m equation (m = n - 4)

m = 4 - 4

m = 0

now we have our m and n, and we can make our ordered pair.

(m, n)

(0, 4)

Answer:

22.75

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

3.5 x 6.5 = 22.75 ft

Answer:

8 feet

Step-by-step explanation:

w = width

2s = length

Find 'w' by multiplying the new dimensions:

(w+5)(2w+3) = 2w² + 3w + 10w + 15 = 99

simplify:

2w² + 13w - 84 = 0

Factor:

(2w + 21)(w - 4) = 0

w = -21/2   ** disregard because a measurement cannot be negative **

w = 4

original width was 4

orginal length was twice 4 or 8 feet

The value of x for the given quadratic equation is (19+[tex]\sqrt{1261}[/tex])/50,

(19-[tex]\sqrt{1261}[/tex])/50.

It is in the form of a[tex]x^{2} +bx+c[/tex]. It is simply an equation and we have to solve for x.

If we solve the given equation we will be able to get the following equation

[tex]25x^{2} -19x-9=0[/tex]

x=(-b+-[tex]\sqrt{b^{2}-4ac }[/tex])/2a

when we put b=19 a =25 c =-9

we will get x=[tex](19+\sqrt{1261} )/50 , (19-\sqrt{1261} )/50[/tex].
