Answer:

B) 63 degrees

Step-by-step explanation:

All triangles equal up to 180 degrees so you would subtract the lengths you are given by 180.

So 180 - 54 = 126

Now you would divide 126 by 2 since this is an isosceles triangle. Isosceles triangles have two equal sides so 126 divided by 2 equals 63 degrees.

So y = 63 degrees

the answer is 63 because 63*2=126 and 126+54=180 and all triangles add up to 180

marishachu [46]

Answer:

$0.288 cm^{3}$

Step-by-step explanation:

To find the volume of a rectangular prism you multiply your length by your width by your height.

$\frac{3}{5} *\frac{4}{5} *\frac{3}{5}\\\\ =\frac{36}{125} \\\\=0.288$

Hope this helps! Have a great day!

Meagan walked 4/10 mile to the park.she walked the same distance home.how much did she walk altogether? Write in simplest form

avanturin [10]

We add them up to find the total distance :

$\dfrac{4}{10} + \dfrac{4}{10} = \dfrac{8}{10} = \dfrac{4 \times 2}{5 \times 2} = \dfrac{4}{5}$

$\text {She walked } \dfrac{4}{5} \text { miles}$

Geometry question for homework.

mars1129 [50]

So remember that the distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

$\sqrt{(4-4)^2+(-2-(-5))^2}\\ \sqrt{0^2+3^2}\\ \sqrt{0+9}\\ \sqrt{9}\\ 3$

Distance between (4,-5) and (4,-2) is 3 units.

$\sqrt{(1-(-1))^2+(1-4)^2}\\ \sqrt{2^2+(-3)^2}\\ \sqrt{4+9}\\ \sqrt{13}$

Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.
