Figure FGH has vertices located at F(1, 3), G(–1, 2), and H(2, 1). The figure is rotated using the origin as the center of rotation. The image has vertices located at F’(3, –1), G’(2, 1), and H’(1, –2). Which rotation could have taken place?
a 45° clockwise rotation
a 90° clockwise rotation
a 90° counterclockwise rotation
a 180° counterclockwise rotation
Answer: The correct option is
(B) a 90° clockwise rotation.
Step-by-step explanation: Given that the co-ordinates of the vertices of figure FGH are F(1, 3), G(–1, 2) and H(2, 1).
The figure FGH is rotated using origin as the center of rotation and the the co-ordinates of the vertices of image figure F'G'H' are F'(3, -1), G'(2, 1) and H'(1, -2).
We are to select the type of rotation that could have taken place.
The transformation from the vertices of FGH to the vertices of image F'G'H' is
F(1, 3) ⇒ F'(3, -1),
G(-1, 2) ⇒ G'(2, 1),
H(2, 1) ⇒ H'(-1, 2).
Therefore, the transformation rule is (x, y) ⇒ (y, -x). This gives the rotation about origin through an angle of 90°.
Thus, the rotation of 90° clockwise taken place from figure FGH to image F'G'H'.
Option (B) is correct.
A baker needs 4 3⁄4 cups of flour. If she uses a 1 1⁄2 cup measuring scoop, how many scoops of flour must the baker use to have at least 4 3⁄4 cups?
Answer:
[tex]3\frac{1}{6}[/tex]
Step-by-step explanation:
Given : A baker needs cups of flour = [tex]4\frac{3}{4} =\frac{19}{4}[/tex]
Solution :
Since we are given that she uses 1 measuring scoop for cup of flour = [tex]1\frac{1}{2} =\frac{3}{2}[/tex]
She uses uses scoop for 1 cup of flour = [tex]\frac{1}{\frac{3}{2}}=\frac{2}{3}[/tex]
She uses scoops for [tex]\frac{19}{4}[/tex] cups of flour = [tex]\frac{2}{3}*\frac{19}{4}[/tex]
= [tex]\frac{19}{6}[/tex]
= [tex]3\frac{1}{6}[/tex]
Thus [tex]3\frac{1}{6}[/tex] scoops of flour must the baker use to have at least 4 3⁄4 cups.

John drives 257 miles and uses 9 gallons of gas. How many miles per gallon did he get? Without calculating the answer, from the choices given, which is most reasonable? A. 100 miles per gallon B. –6 miles per gallon C. 30 kilometers per liter D. 25 miles per gallon
Answer:
Option D
Step-by-step explanation:
Given that John drives 257 miles and uses 9 gallons of gas.
we can find unit rate as
Per galon mileage given = 257/9 = 28
ANd units are miles/gallon
100 miles per gallon is very far from 28 hence incorrect
6 miles per gallon is very low
30 is right but unit is wrong
Hence option D is the right answer.

How many different outcomes are possible if you can choose between a bus or a train, full fare or concession and you can travel in the morning or the afternoon?
Applying the multiplication principle in probability, there are eight different combinations possible when choosing between bus or train, full fare or concession, morning or afternoon for your travel.
Explanation:Your question is asking how many different combinations of travel mode, fare type, and time of day are possible under given conditions. For this situation, we can apply simple probability rules with concept of multiplication principle, which states that if there are n ways to do something, and m ways to do another, then there are n * m ways to do both.
In this case, you have two choices for each category: mode of transportation (bus or train), fare type (full fare or concession), and time of day (morning or afternoon). The combination is simply 2 (mode of transport) * 2 (fare type) * 2 (time of day) = 8. So, there are eight possible outcomes.

the sum of two numbers is 40. the sum of the smaller and 5 times the larger is 144. find the numbers.
To find the two numbers, we can solve a system of equations. The smaller number is 14 and the larger number is 26.
Explanation:To find the two numbers, we can solve a system of equations based on the given information. Let's represent the smaller number as x and the larger number as y.
From the first equation, we have x + y = 40.From the second equation, we have x + 5y = 144.We can solve this system using substitution or elimination. Let's use substitution:
From the first equation, solve for x: x = 40 - y.Substitute this value of x into the second equation: (40 - y) + 5y = 144.Simplify the equation: 40 + 4y = 144.Subtract 40 from both sides: 4y = 104.Divide both sides by 4: y = 26.Substitute this value of y back into the first equation to find x: x + 26 = 40. Subtract 26 from both sides: x = 14.Therefore, the smaller number is 14 and the larger number is 26.

What is the measure of the angle formed by the minute hand and the hour hand of a clock when the clock shows 4:00?
Answer:
[tex]120^o[/tex]
Step-by-step explanation:
We are asked to find the measure of the angle formed by the minute hand and the hour hand of a clock when the clock shows 4:00.
Since we know that clock is a circle made of 360 degrees.
Angle described by minute hand in one minute equals to 6 degrees (360/60). Angle described by hour hand in 1 hour equals 30 degrees (360/12).
At 4:00 minute hand will be at 12 and hour hand will be at 4. So we will multiply 4 by 30 to find the measure of angle formed when the clock shows 4:00.
[tex]\text{Measure of angle}=4\times 30^o[/tex]
[tex]\text{Measure of angle}=120^o[/tex]
Therefore, the measure of the angle formed by the minute hand and the hour hand of a clock, when the clock shows 4:00 is 120 degrees.
