Step-by-step explanation:

7, HT= \sqrt{8^2 + 15^2} =17 cm

8, S = 1/2.AC.BC.sinC≈28,01 cm^2

9, S =1/2.SR.RT.sin R≈ 3615,7 m^2

Prove:

the area of the ABC triangles is S

sin A = BH/AB

S = 1/2 BH.AC=1/2 sinA.AB.AC=1/2*c*b*sinA

A recipe calls for 4 cups of flour. Lauren wants to make 20% more servings than the recipe makes. Which expression represents ho
ale4655 [162]
C. 6/5 * 4

6/5 = 1.20 where .20 represents the 20% increase in serving.

1.20 * 4 = 4.8 is the total cups of flour needed to increase serving by 20%

4 is the 100% ; the desired increase is 20%; therefore: 100% + 20% = 120% based on 4 cups. So, 120% ÷ 100% = 1.2 * 4 = 4.80 cups

The point slope form of the eqaution of the line that passes through (-5,-1) and (10, -7) is y+7= -2/5 (x - 10) what is the stan
stira [4]

Answer:

<h2>2x + 5y = -15</h2>

Step-by-step explanation:

The standard form of an equation of a line:

Ax+By=C

We have the equation in point-slope form:

y+7=-\dfrac{2}{5}(x-10)

Convert it to the standard form:

y+7=-\dfrac{2}{5}(x-10)     <em>multiply both sides by 5</em>

5y+35=-2(x-10)         <em>use the distributive property </em><em>a(b + c) = ab + ac</em>

5y+35=(-2)(x)+(-2)(-10)

5y+35=-2x+20          <em>subtract 35 from both sides</em>

5y=-2x-15            <em>add 2x to both sides</em>

2x+5y=-15

Can u help with these two
Artemon [7]
The volume of a rectangular prism can be given by the form
V= b*h*w

you know Volume, base, and height but you dont know width

so divide b and h to both sides
\frac{V}{b*h} = w
and you cna solve for width

now for 6.
dividing by a number is the same as multiplying by its reciprocal

n \div 6  = n * \frac{1}{6}
