Answer:

240

Step-by-step explanation: 80 words in 4 minutes = 160 words in 8 minutes, 160 +80 = 240

Answer:

she can type 240 words i think

4.3=12

80.3=240

Answer:

you use the Pythagorean theorem (a^2 +b^2 = c^2)

a^2 +17^2 = 19^2

a^2 + 289 = 361

a^2 = 72

a = (square root)72

5^2 + 13^2 = c^2

25 + 169 = c^2

194 = c^2

c= (square root)194

a^2 + 10^2 = 20^2

a^2 + 100 = 400

a^2 = 300

a = (square root) 300

5^2 + 14^2 = c^2

25 + 196 = c^2

221 = c^2

c= (square root) 221

Step-by-step explanation:

it says to leave it as it's simplest radical form, i can't put a square root on the screen, but put the number inside the radical and leave it like that.

Answer:

c = 58x

Step-by-step explanation:

A linear equation is an equation in the form of f(x) = mx + c. Where m is the slope and c is the intercept.

Let the price of one guitar lessons be x, then 47guitars will be 47x and 11 guitar lessons will be 11x. All together will be 47x + 11x = 58x.

Thus, the total cost, c, is

c = 58x

Answer:

m= -2

X1=3 Y1= -1

Y-Y1=m(X-X1)

Y-(-1)= -2(X-3)

Y+1= -2X+6

Y=-2X+6-1

Correct question

A sequence is defined by the term-to-term rule

Un+1 = u. + 3

Given that u1 = 1,

a) find u2

b) find u3

c) find u5

a) Given the recursive formula;

Un+1 = un + 3

When n = 1;

U1+1 = U1 + 3

U2 = U1 + 3

U2 = 1 + 3

U2 = 4

b) U3 = U2 + 3

U3 = 4 + 3

U3 =7

c) U4 = U3 + 3

U4 = 7+3

U4 = 10

U5 = U4 + 3

U5 = 10 + 3

U5 = 13

Note that the question was assumed. The same calculation can be employed for nay other term

[tex]\huge\boxed{t=3}[/tex]

Step-by-step explanation:

[tex]-5(t+3)=-30[/tex]

[tex]-5(t+3)=-30[/tex]    divide both sides by (-5)

[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]

[tex]t+3=6[/tex]       subtract 3 from both sides

[tex]t+3-3=6-3\\t=3[/tex]

[tex]-5(t+3)=-30[/tex]       use the distributive property a(b + c) = ab + ac

[tex](-5)(t)+(-5)(3)=-30[/tex]

[tex]-5t-15=-30[/tex]     add 15 to both sides

[tex]-5t-15+15=-30+15[/tex]

[tex]-5t=-15[/tex]         divide both sides by (-5)

[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]

Answer:

There were 7 players on the Bears

Step-by-step explanation:

Given

[tex]a = falcons[/tex]

[tex]b = bears[/tex]

We have that:

[tex]a = 11[/tex]

and also:

[tex]a = 2b - 3[/tex] --- 3 fewer than twice a

Required

Solve for b

Substitute 11 for a in [tex]a = 2b - 3[/tex]

[tex]11 = 2b - 3[/tex]

Add 3 to both sides

[tex]3+11 = 2b - 3+3[/tex]

[tex]3+11 = 2b[/tex]

[tex]14 = 2b[/tex]

Divide both sides by 2

[tex]\frac{14}{2} = \frac{2b}{2}[/tex]

[tex]7 = b[/tex]

[tex]b = 7[/tex]

Hence, there were 7 players on the Bears

Answer:

x=3

Step-by-step explanation:

7−3x=−x+1

Step 1: Simplify both sides of the equation.

7−3x=−x+1

7+−3x=−x+1

−3x+7=−x+1

Step 2: Add x to both sides.

−3x+7+x=−x+1+x

−2x+7=1

Step 3: Subtract 7 from both sides.

−2x+7−7=1−7

−2x=−6

Step 4: Divide both sides by -2.

−2x

−2

=

Answer:

[tex]16^\circ, 88^\circ, 76^\circ[/tex]

Step-by-step explanation:

Given a triangle.

One of the angles is [tex]8^\circ[/tex] more than 5 times of one angle.

Third angle is [tex]4^\circ[/tex] more than the difference of two angles.

To find:

The angles.

Solution:

Let the first angle = [tex]x^\circ[/tex]

As per question statement, second angle = 5[tex]x^\circ[/tex] + [tex]8^\circ[/tex]

And third angle = 5[tex]x^\circ[/tex] + [tex]8^\circ[/tex] - [tex]x^\circ[/tex] + [tex]4^\circ[/tex] = [tex](4x+12)^\circ[/tex]

Using triangle sum property that the sum of all the internal angles of a triangle is always equal to [tex]180^\circ[/tex].

[tex]x+5x+8+4x+12 = 180\\\Rightarrow 10x+20=180\\\Rightarrow 10x = 160\\\Rightarrow x = 16[/tex]

Therefore, the first angle = [tex]x^\circ = 16^\circ[/tex]

The second angle = [tex]5x+8 = 5 \times 16 + 8 = 80+8 = 88^\circ[/tex]

The third angle = [tex]4x+12 = 4\times 16 + 12 = 76^\circ[/tex]

Therefore, the angles are [tex]16^\circ, 88^\circ, 76^\circ[/tex].

Graph-X represents the given set of inequalities.

"An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions."

Given two inequalities are:

1. y > (1/3)x - 2

If we compare it with the slope-intercept form of a line, then:

Slope = 1/3, y-intercept = - 2

Therefore, the line cuts the y-axis at x = - 2.

Here, the greater than sign indicates that the graph would be shaded down.

2. y < - 4x - 2

If we compare it with the slope-intercept form of a line, then:

Slope = - 4, y-intercept = - 2

Therefore, the line cuts the y-axis at x = - 2.

Here, the less than sign indicates that the graph would be shaded up.

Therefore, Graph-X represents the given set of inequalities.
