The sum of 13 and Rhonda's height is 74. Use the variable r to represent Rhonda's height.

The equation is 13+r = 74. This is because the term "sum" means we add two or more values.

That equation solves to r = 61 after subtracting 13 from both sides.

Assuming the r value is her height in inches, it means Rhonda is 61 inches tall (i.e. 5 feet, 1 inch)

Let u = &lt;-9, 4&gt;, v = &lt;8, -5&gt;. Find u - v. <br> URGENT
Pie

To subtract vectors, you simply have to subtract correspondent coordinates.

So, if you have

u = \langle u_1,\ u_2,\ldots u_n\rangle ,\quad v = \langle v_1,\ v_2,\ldots v_n\rangle

the subtraction is simply

u-v = \langle u_1-v_1,\ u_2-v_2,\ldots u_n-v_n\rangle

So, in your case, we have

\langle-9,4\rangle-\langle 8,-5\rangle=\langle -9-8, 4+5\rangle=\langle -17,9\rangle

If -6x + 12 = 0 and 4y + 5 =9 <br> what is the value of x + y
slega [8]

Answer:

x=2

y=1

Step-by-step explanation:

-6x+12=0

take 12 to the other side &it becomes negated then equate

-6x=-12

the negatives cancel out each other and therefore the answer is positive

x=2

4y+5=9

take 5 over to the other side &it becomes negated

4y=9-5

4y=4

y=1

A company provides snack-sized packages of nuts for its office employees.
DaniilM [7]

The probabilities that correctly complete this probability distribution for 50 packages of nuts will be 0.24, 0.2, 0.12, 0.28, and 0.16.

<h3>How to calculate the probability?</h3>

From the information given, we have to find the probability for each fruit. This will be:

Almond = 12/50 = 0.24

Cashew = 10/50 = 0.2

Mixed = 6/50 = 0.12

Peanut = 14/50 = 0.28

Pecan = 8/50 = 0.16

Therefore, the probabilities that correctly complete this probability distribution for 50 packages of nuts will be 0.24, 0.2, 0.12, 0.28, and 0.16.

The endpoints of a line segment are A(-7, -2) and B(2, 4). The segment partition is (-3.4, 0.4). Find the ratio. HELP ASAP!!
Otrada [13]

Answer:

4.33 : 6.49

Step-by-step explanation:

Given endpoints as A(-7,-2) and (2,4) find the length of the segment

d=√ (x₂-x₁) + (y₂-y₁)²

d=√ (2--7)² + (4--2)²

d=√ 9² + 6²

d= √ 81 +36

d=√117 =10.82

The partition is at (-3.4,0.4)

The length from A to the partition will be

A(-7,-2)    (-3.4,0.4)

√ (-3.4--7)² + (0.4--2)²

√ 3.6²+2.4²

√18.72 = 4.33

Length of segment from partition to end point B

(-3.4,0.4)   ,  B(2,4)

√(2--3.4)²+(4-0.4)²

√ 5.4² + 3.6²

√42.12

=6.49

The ration that results from the partition of the segment is;

4.33 : 6.49
