Answer:

Step-by-step explanation:

this one is tricky    so b/c the lines are at 90 degees we know that the arcs are similar so set up the parts of the arcs equal to 360 degrees

360 = 130  + 130  + x + x

see each part of the circle ?

then use your mad algebra skilz

100 = 2x

50 = x

ian is trying to estimate the distance across the lake d. he knows the measures shown in the diagram. which estimate is closest
masya89 [10]

Answer:  The estimate is closest to the distance d is 4.2 miles


Step-by-step explanation:

In the given image, we can see that there is a right triangle, in which d is the side opposite to the right angle (largest angle in the triangle) which means its the longest side of the triangle.

[Since side opposite to the larger angle is larger]

Therefore, by Pythagoras Theorem we have

d^2=(3.6)^2+(2.2)^2\\\Rightarrow\ d^2=12.96+4.84\\\Rightarrow\ d^2=17.8\\\Rightarrow\ d=\sqrt{17.8}\\\Rightarrow\ d=4.2190\approx4.2

The estimate is closest to the distance d is 4.2 miles.

Please answer this correctly
aleksley [76]

Answer:

16 ounces of clay he need.

Step-by-step explanation:

Given:

Reggie had 2-pound bricks of clay and his job is to give 4 ounces of clay to each student.

There are total 28 students.

Now, to get how much ounces of clay does the each student  have first we multiply the number of students to the number of ounces of clay.

Number of students × Number of ounces of clay:

28\times 4

112

Now, total amount of clay ounces Reggie had= 3×32=96 ounces. (1 pound = 16 ounces, 2 pound = 32 ounces.)

So, the total amount of clay he need is = 112-96

                                                                 = 16

Therefore, 16 ounces of clay he need.

Luden [163]

Hey there! I'm happy to help!

You ran a 10 kilometer race in 56 minutes (good job!). To find how much you ran in 1 minute, you simply divide by 56.

10/56=0.178571428

Therefore, you ran around 0.18 km/minute.

Have a wonderful day! :D
