Which subtraction expression does the number line model show?

Answer: 1.50 seconds

Step-by-step explanation:

Let x = Time taken by Firework A to explode( in seconds ).

Time taken by Firework B = x+ 0.25 seconds

Distance covered = Time × Speed

Distance covered by Firework A = 240 x

Distance covered by Firework B = 200 (x+0.25) = 200x+50

When both at same height , then

240x = 200x+50

⇒ 240x- 200x =50

⇒40x =50

⇒ x = 1.25

Total time = x+ 0.25 = 0.25+ 1.25 = 1.50 seconds

Hence. after Firework B launches it will take 1.50 seconds to launch.

Answer:

[tex]129^{\circ}[/tex]

Step-by-step explanation:

n = Number of sides of a polygon = 7

The interior angles of a polygon is given by

[tex]\theta=\dfrac{(n-2)180^{\circ}}{n}[/tex]

[tex]\Rightarrow \theta=\dfrac{(7-2)\times 180^{\circ}}{7}[/tex]

[tex]\Rightarrow \theta=\dfrac{5\times 180^{\circ}}{7}[/tex]

[tex]\Rightarrow \theta=\dfrac{900^{\circ}}{7}[/tex]

[tex]\Rightarrow \theta=128.57^{\circ}\approx 129^{\circ}[/tex]

Each interior angle of a heptagonal nut is [tex]129^{\circ}[/tex].

Step-by-step explanation:

[tex]\frac{1}{2}+\frac{1}{3}=\frac{1*3}{2*3}+\frac{1*2}{3*2}\\\\= \frac{3}{6}+\frac{2}{6}\\\\= \frac{5}{6}[/tex]

[tex]a^{m}*a^{n} = a^{m+n}[/tex]

[tex]\sqrt{5}*\sqrt[3]{5}=5^{\frac{1}{2}} * 5^{\frac{1}{3}}\\\\= 5^{\frac{1}{2}+\frac{1}{3}}\\\\= 5^{\frac{5}{6}}\\\\= \sqrt[6]{5^{5}}[/tex]

Answer: [tex]45.21^{\circ }[/tex]

Step-by-step explanation:

Given

[tex]\angle J=90^{\circ }[/tex]

HI=88 ft

IJ=62 ft

From the figure, we can write

[tex]\cos I=\frac{IJ}{HI}=\frac{62}{88}=\frac{31}{44}\\I=\cos^{-1} (\frac{31}{44})=45.207^{\circ }\approx 45.21^{\circ }[/tex]

Answer:

8=73 degrees

5=107 degrees

Step-by-step explanation:

Please mark me brainliest :D

Answer:

Angle 5 is 107 degrees

Angle 8 is 7s degrees

Step-by-step explanation:

First find angle 5. Since the lines are parallel and cut by a transversal, we can say that Angle 3 and Angle 5 are congruent (same measure) since they are alternate interior angles.

Since Angle 3 is 107 degrees, Angle 5 would also be 107 degrees.

Angle 8 is supplementary to Angle 5.

Angle 5 + Angle 8 = 180

Since we know Angle 5 is 107: 107 + Angle 8 = 180

Angle 8 would then be 73 degrees.

   -4 =  ——  =  ——————

         1        8     8    

Step-by-step explanation:

the answer is m<-32

The solution of inequality m/8 < 4 is,

⇒ m = 32

Which is shown in graph of image.

A relation by which we can compare two or more mathematical expression is called an inequality.

We have to given that;

The expression of the inequality is,

⇒ m/ 8 < 4

Now, We can simply the expression as;

⇒ m/ 8 < 4

⇒ m/ 8 - 4 < 0

⇒ (m - 32)/8 < 0

⇒ m - 32 < 0

⇒ m < 32

Therefore, The solution of inequality m/8 < 4 is,

⇒ m = 32

Which is shown in graph of image.
