Answer:

Step-by-step explanation:

angle C + Angle B= Angle A(sum of two interior oppposite angles are equal to the exterior angle formed)

61+B=143

B=143-61

B=82 degree

We know that,

→ C = 61°

[A = B + C]

→ 143° = B + 61°

→ B = 143° - 61°

→ B = 82°

[180° = A + B + C]

→ 180° = A + (82° + 61°)

→ A = 180° - 143°

→ A = 37°

What is the distance between (-5, -5)(−5,−5)left parenthesis, minus, 5, comma, minus, 5, right parenthesis and (-9, -2)(−9,−2)le

Anastasy [175]

Answer:

$5 \:Units$

Step-by-step explanation:

Given points (-5,-5) and (-9,-2), the distance between the two lines is determined using the Distance Formula.

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\lim_{n \to \infty} a_n where (x_1,y_1)=(-5,-5), (x_2,y_2)=(-9,-2)\\Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\=\sqrt{(-9-(-5))^2+(-2-(-5))^2}\\=\sqrt{(-9+5)^2+(-2+5)^2}\\=\sqrt{(-4)^2+(3)^2}\\=\sqrt{16+9}\\=\sqrt{25}=5 \:Units$

The distance between the points (-5,-5) and (-9,-2) is 5 Units.

A metallurgist has one alloy containing 30% copper and another containing 62% copper. How many pounds of each alloy must be used

Illusion [34]

The metallurgist would need 46.875 lb of an alloy containing 30 % copper and 3.125 lb of an alloy containing 62 % copper to produce 50 lb of a third alloy.

<h3>How to estimate proportions of ingredients for an alloy by weighted averages</h3>

In this question we must prepare a <em>third</em> alloy by using correct quantity of two alloys with different <em>copper</em> concentrations. <em>Required</em> weights can be determined by applying concept of <em>weighted</em> average:

(32/100) · (50 lb) = (30/100) · x + (62/100) · (50 - x)

32 · 50 = 30 · x + 62 · (50 - x)

32 · 50 = 30 · x + 62 · 50 - 62 · x

32 · x = 30 · 50

x = 46.875

The metallurgist would need 46.875 lb of an alloy containing 30 % copper and 3.125 lb of an alloy containing 62 % copper to produce 50 lb of a third alloy.
