8 0

Answer:

T'(-1, 4), U'(8, 4) and V'(-1, 10)

Step-by-step explanation:

If we reflect the vertices of the given triangle VTU across a line y = 3,

Rule to followed for the image points,

Line of reflection will work as a mirror.

And distance of image points and original points will be same from the line of reflection.

Therefore, Coordinates of the vertices of the image triangle will be,

T'(-1, 4), U'(8, 4) and V'(-1, 10)

Juan and his little brother Miguel ran around a circular track together. Juan ran on the inner track, which has a radius of 30 f

eduard

Answer:

80pi-60pi

Step-by-step explanation:

To find how much Juan ran, we must find the circumference.

pi *30*2=60*pi (which is how much Juan ran.)

pi*40*2=80*pi (which is how much Miguel ran)

80pi-60pi would be how much farther Miguel ran than Juan.

What is the answer for -7 +4

lianna [129]

Answer:

answer is -3

Step-by-step explanation:

we know -,+ is -. so minus, plus is minus(here minus and plus are the signs given. opposite signs give minus wheras same signs give plus)

so, first we should subtract 7 minus 4 is 3,.

then we should insert the minus because the greater number has the minus sign. ( you should always insert a sign of a greater number after substituting)

Answer:

1. m∠B=110°

2. 560 cm3

3. Numerical data

4. 2000 cm3

5. 50%

Step-by-step explanation:

1. The explanation of part 1 is given in the attachment.

2. Given dimensions : 10 cm, 8 cm, and 7 cm.

Let Length of cuboid =10 cm

breadth/width of cuboid =8 cm

height of cuboid = 7cm

Volume of cuboid = length *width* height

=( 10 *8*7) cm3

=(560) cm3

3. Age, Birth date and weight are the types/examples of "Numerical Data" because these all are describe in terms of numeric values.

4. 1 liter = 1000 cm3 or 1 cm3 = 0.001 liter

1.5 liters =(1.5*1000) cm3 = (15*100) =1500 cm3

1 dm3 =1000 cm3

0.35 dm3 = (0.35*1000) cm3 = (35*10) cm3 =350 cm3

Given expression: 1.5 litre + 0.35 dm3 + 150 cm3 = cm3

1500 cm3 + 350 cm3 +150 cm3 = 2000 cm3

5. If A=(1/2)B, then B : A = 50 %

Ratio: B : A

B : (1/2) B

1: (1/2)

50 % (The value of A is half of the value of B)
