A) (x,y)->(4x,4y) because the x and y values are multiplied by 4 when dilated. Ex. U(-1,1) was dilated to U’(-4,4). -1 was multiplied by 4 to get -4 for the x value and 1 was multiplied by 4 to get 4 for the y value.
5:8
X:7
Cross multiply :
= 7(5)=8x
35=8x
Now divide both sides by 8
35/8= x
x= 4.375
Answer:
b
Step-by-step explanation:
<u><em>Matteo is 4 inches taller than Nico. </em></u>
<u><em>Sarah is wrong because she didn't consider the conversion rate from ft to inches. </em></u>
Height of Matteo = 4 feet 3 inches
Height of Nico = 3 feet 11 inches.
- Now to find the difference in height, we need to first convert both of their heights to inches.
From conversion tables, we know that;
12 inches = 1 ft.
- Thus, their height in inches is;
Height of Matteo = (4 × 12) + 3 = 51 inches
Height of Nico = (3 × 12) + 11 = 47 inches
Thus, difference in height = 51 - 47 = 4 inches.
Thus, Matteo is 4 inches taller than Nico.
- Looking at the method of Sarah, she didn't consider that the unit she was working with. If it was just units and tens subtraction, that method would have worked but she ought to have added 12 to 3 since it is from ft to inches instead of 10 to 3 as in the case of regular numbers without units.
