Answer:

136

Step-by-step explanation:

to find the triangle's surface area, you do the height (4) multiplied by the base (6). Then for the rectangles, you multiply the width (5 or 6) by the length (7). Then you add up all the numbers to get your answer.

Identify the reflection rule on a coordinate plane that verifies that triangle A(-1,7), B(6,5), C(-2,2) and A'(-1,-7), B'(6,-5),
malfutka [58]

Answer:

Option B is correct.

The reflection rule is followed here is,  (x,y) \rightarrow (x, -y).

Explanation:

Since, the triangle is reflected over the x-axis , then only y- coordinates will get changed but the x coordinates will remain the same.

A(-1,7) \rightarrow A'(-1,-7)

B(6,5) \rightarrow B'(6,-5)

C(-2,2) \rightarrow C'(-2,-2)

Therefore, the only reflection rule on the coordinate plane that verifies the triangle are congruent when reflected over x-axis is, (x,y) \rightarrow (x, -y)

Find the measure of the larger angle.<br><br><br><br> 51°<br> 180°<br> 129°<br> 32°
kozerog [31]

Answer:

129

Step-by-step explanation:

for this one they gave us to angles and if you didnt know those angles are supplementary so they are going to add up to equal 180 so first things first is we want to find the value of x, to do that we do

180=x+19+4x+1

step 1 combine like terms

4x+x=5x

19+1=20

now we have

180=20+5x

step 2 subtract each side by 20

20-20 cancels out

180-20=160

now we have

160=5x

step 3 divide each side by 5

5/5 cancels out

160/5 = 32

x=32

now we want to plug in 32 for each expression to find which one is greater

(32)+19=51

4(32)=128

128+1=129

so the answer is 129

hope this helps :D

2. Three bells P, Q and R ring at intervals of 40, 48and 60 minutes respectively. If they ring together at 6.15 a.m. when will t
MAXImum [283]
They will ring again together at 10:15am. Because the common factor for 40, 48 and 60 is 240, which means 240 minutes, that equals to 4 hours. Hence 4 hours after 6.15am is 10.15am.

Hope this helps.
