Answer:
9
Step-by-step explanation:
13 - 5 = 8
8 / 2 = 4
13 - 4 = 9
Answer:
Step-by-step explanation:
This is a isosceles triangle, An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length.
A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
Answer: 3.6cm
Step-by-step explanation:
Using the volume formula; solve for a;
![a^2=\frac{V}{h}\\ a=\sqrt[]{\frac{V}{h} }](https://tex.z-dn.net/?f=a%5E2%3D%5Cfrac%7BV%7D%7Bh%7D%5C%5C%20a%3D%5Csqrt%5B%5D%7B%5Cfrac%7BV%7D%7Bh%7D%20%7D)
![a=\sqrt[]{\frac{104cm^3}{8cm} }](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B%5D%7B%5Cfrac%7B104cm%5E3%7D%7B8cm%7D%20%7D)
![a=\sqrt[]{13cm^2}](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B%5D%7B13cm%5E2%7D)
Answer:
Bean should do at least 6 lessons a day for a week to not go to summer school.
OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.
The correct answer is D) 192.
Hope this helps
cheers,
