Answer 1

Answer:

Answer:

$29000 with a margin of error of $5000

Step-by-step explanation:

We have that the midpoint between the given values is

(X1+X2) / 2 = ($34000+$24000)/2 = $29000

We have that the midpoint between the given values would be

(X2-X1)/2=($34000-$24000)/2=$10000/2=$5000

So I can write that approach as $29000 with a margin of error of $5000

Done

at a neighboring school, the ratio from boys to girls is 6:5. There are 209 students in the school. How many are girls?

Answers

There are several important information's already given in the question. Based on those given information's the answer to the question can be easily deduced.
Total number of students in the school = 209
Ration of the boys to girls in the school = 6:5
Let us assume the common ratio to be = x
Then
6x + 5x = 209
11x = 209
x = 209/11
= 19
Then
The number of girls in the school = 19 * 5
= 95
So there are a total of 95 girls in the school that has a total of 209 students.

Calculate the area of triangle QRS with altitude ST, given Q (0, 5), R (−5, 0), S (−3, 4), and T (−2, 3).A- 6.2 square units

B- 7 square units

C- 5.9 square units

D- 5 square units

Answers

we have that

$Q (0, 5)\nR (-5, 0)\nS (-3, 4)\nT (-2, 3)$

using a graph tool

see the attached figure

the Area of triangle QRS is equal to

$A=(1)/(2)*b*h\n A=(1)/(2)*RQ*ST$

1) Find the distance RQ

Applying the formula of distance

$d=\sqrt{(y2-y1)^(2)+(x2-x1)^(2)}$

$dRQ=\sqrt{(0-5)^(2)+(-5-0)^(2)}$

$dRQ=√((25)+(25))$

$dRQ=√(50) units$

2) Find the distance ST

$dST=\sqrt{(3-4)^(2)+(-2+3)^(2)}$

$dST=√((1)+(1))$

$dST=√(2) units$

3) Find the area of triangle QRS

$A=(1)/(2)*RQ*ST\n\n A=(1)/(2)*√(50)*√(2) \n\n A=(1)/(2)*√(100) \n \n A=(10)/(2) \n \n A=5 units^(2)$

therefore

the answer is the option

D- $5$ square units

The correct answer among the choices provided is option D. The area of triangle QRS with altitude ST is 5 square units. To solve for the area, the distance formula was used. The formula was substituted with the given values, QR=√[(-5-0)²+(0-5)²].

In which quadrant are the y-coordinates of a point negative? Choose all answers that are correct. A. I B. II C. III D. IV

Answers

Quadrant I is top right
Quadrant II is Top Left
Quadrant III is Bottom Left
Quadrant IV is Bottom right.

This is how I like to think of it.

(x, y)

I = (+, +)
II = (-, +)
III = (-, -)
IV = (+, -)

So the answer would be either Quadrant 3 or 4 (Bottom Right or bottom left)

I hope this helps you!

draw a model to represent the problem. 2/3 divided into 1/3 size pieces. how many 1/3 pieces will be in 2/3?

Answers

that shows the answer of how to do it

Which is greater 1/3 or 1/8

Answers

1/3= 0.333333

1/8=0.125

So definitely 1/3 is bigger.

1/3 is greater because it is equal to 0.33333......
1/8 is equal to 0.125. :D
