Cost of the toothbrush and the toothpaste together = $1.10
Let us assume the cost of the toothpaste = x
Then
The cost of the toothbrush is = (x + 1) dollar
Then we can write the equation as
x + x+ 1 = 1.10
2x + 1 = 1.10
2x = 1.10 - 1
2x = 0.10
x = 0.10/2
  = .05 dollars
So the cost of the toothpaste is 0.05 dollars.<span>I hope the procedure is clear to you.</span>

WHO DOESN'T LOVE MAX POINTS. MAX POINT QUESTION<br> PLS ANSWER THIS TRIGONOMETRY QUESTION
mezya [45]

Answer:

Solution given:

opposite:9

adjacent: 12

\theta=?

Relationship between opposite and adjacent is given by tan angle

so

Tan \theta=\frac{opposite} {adjacent}=\frac{9}{12}

Tan \theta=\frac{3}{4}

\theta=Tan^{-1}\frac{3}{4}

\bold{\theta=36.8°}

#11.

hypotenuse[h]=11cm

opposite/perpendicular[P]=b cm

adjacent/base[b]=a cm

now

\theta=62°

Relationship between height and hypotenuse is given by Sin angle

:.

Sin 62°=\frac{opposite}{hypotenuse}=\frac{b}{11}

doing crisscrossed multiplication

b=Sin 62°*11

:.b=9.71 cm

a) At <u>9</u><u>.</u><u>7</u><u>1</u><u> </u>cm height does the ladder touch the building.

again

Relationship between base and hypotenuse is given by Cos angle

:.Cos 62°=\frac{base}{hypotenuse}=\frac{a}{11}

doing crisscrossed multiplication

a=Cos 62°×11

a=5.16cm

b) the distance between the foot of the ladder and the building is <u>5.16cm.</u>

Question 5 of 10
True [87]

Answer:

The median value of the houses is $169,000

Step-by-step explanation:

Since the houses were undervalued by $15,000, add $15,000 to all amounts

154,000 + 15,000 = 169,000

133,000 + 15,000 = 148,000

167,000 + 15,000 = 182,000

145,000 + 15,000 = 160,000

180,000 + 15,000 = 195,000

172,000 + 15,000 = 187,000

149,000 + 15,000 = 164,000

To take the median of the data set, order the numbers from least to greatest

148,000   160,000   164,000   169,000   182,000   187,000   195,000

Eliminate one number from both sides until you reach one number

The number is 169,000
