8 0

Answer:

100deg

Step-by-step explanation:

you can use this rule: Vertically opposite angles

since all angles in a line are supplementary, the angle beside the 100deg is 80deg (180-100) and so u take 180-100 again to get the ? deg

What graph represents the system of linear inequalities? 4x+y>1 y≤32x+2

castortr0y [4]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$4x+y>1$ -----> inequality A

The solution of the inequality A is the shaded area above the dashed line

The equation of the dashed line is $4x+y=1$

The slope of the dashed line is negative

The y-intercept of the dashed line is the point $(0,1)$

The x-intercept of the dashed line is the point $(0.25,0)$

$y\leq \frac{3}{2}x+2$ -----> inequality B

The solution of the inequality B is the shaded area below the solid line

The equation of the solid line is $y=\frac{3}{2}x+2$

The slope of the solid line is positive

The y-intercept of the solid line is the point $(0,2)$

The x-intercept of the solid line is the point $(-1.33,0)$

The top of a gate post is in the shape of a square pyramid. The height of the pyramid is 5 inches and each side of the base is 7

Delvig [45]

Answer:

91.3 in³

Step-by-step explanation:

The formula for the volume of a pyramid is:

V = $\frac{1}{3}Bh$ where B=area of the base and h=height of the pyramid

Given the dimensions in the problem and that the pyramid has a square base, we can first calculate the area of the base:

A = 7.4 x 7.4 = 54.76 in²

Multiply the area of the base x height of the pyramid: (54.76 x 5) = 273.8

Divide by 3 (multiply by $\frac{1}{3}$ ): 273.8/3 ≈ 91.3 in³

Factor 7w2−175.(1 point) −7(w−25) 7(w−25) 7(w−5)(w+5) 7(w−5)(w−5)

Nutka1998 [239]

Answer:

7(w + 5)(w -5)

Step-by-step explanation:

a² - b² = (a + b)(a - b)

7w² - 175 = 7w² - 7*25

= 7(w² - 25)

= 7(w² - 5²)

= 7(w + 5)(w -5)
