Answer:

see details and attached figure below.

Step-by-step explanation:

Going row by row

1. 12  (isosceles triangles have equal legs from the vertex)

2. 55 deg. (isosceles triangles have equal base angles)

3. 90 = 180-45-45 (isosceles triangles have equal base angles)

4. 2x-8 = 10

=> x = 18/2 = 9 (isosceles triangles have equal legs from the vertex)

5. sum of angles of triangle = 180

3x+3x+2x+4 = 180 => 8x = 176, x = 22, angle A = 3x = 66 deg.

6. sum of angles of triangle = 180

(isosceles triangles have equal base angles)

25+25+angle Z = 180 => angle Z = 180-25-25 = 130

VikaD [51]

Given :

Susan wanted to share her 37 seashells with her two younger brothers.

To Find :

If she divided her seashells between the three of them, how many would each person get.

Solution :

Let, each person will get x seashells.

So,

x = \dfrac{\text{Total number of seashells}}{\text{Number of persons}}\\\\x = \dfrac{37}{3}\\\\x = 12.333

But as we know seashells cannot be in decimal.

Therefore, each person will get exactly 12 shells.

wolverine [178]

Answer:

19.5 ounces of spices

Step-by-step explanation:

Raheem made 14 ounces of curry sauce which contained (among other things), 3.25 ounces of spices. He wants to make a larger batch for a family dinner and decides he will need a total of 84 ounces of sauce altogether. How many ounces of spices will he need to complete his recipe?

The question above is calculated as:

14 ounces of sauce = 3.25 ounces of spices

84 ounces of sauce = x ounces of spices

Cross Multiply

14x = 84 × 3.25

x = 84 × 3.25/14

x = 19.5 ounces of spices

Hence, for 84 ounces of curry sauce he would need 19.5 ounces of spices

Select the graphs that have an equation with a < 0.
Eddi Din [679]

Answer:

Second graph only.

Step-by-step explanation:

The standard equation of a parabola is ax^2+bx+c where a,b and c are coefficients.

If the coefficient of (a) is positive then the parabola is concave upwards (as in picture 1)

If the coefficient of (a) is negative then the parabola is concave downwards as in picture 2.
