Answer:

the number of hours taken is 2

Step-by-step explanation:

The computation of the number of hours taken is shown below:

As we know that

Distance = travel time × speed

The Guillermo to catch Dorabella be t = T

So the equations would be

9T = 4 + 7T

9T - 7T = 4

2T = 4

T = 2 hours

hence, the number of hours taken is 2

In a class, every student knows French or German (or both). 15 students know French, and 17 students know German.
leva [86]
Answer:
32 students

Explanation:
We are given that:
Students in the class can either speak French, German or both
15 students know French
17 students know German

Now, the maximum number in the class can be calculated by assuming that no student can speak both languages.
This means that the number of students will be the summation of those who know French only (15) and those who know German only (17)

In this case:
the maximum number of students = 15 + 17 = 32 students 

Hope this helps :)

Anyone know what the answer is? I'd appreciate it if someone could help because im stuck
andrew-mc [135]

Answer:

100

Step-by-step explanation:

Isosceles triangle have 2 equal angles. Therefore the second angle in the triangle will also be 25.

Since the sum of angles in a triangle is 180.

180-(25x2) will give you the last angle in one of the triangles.

The other angle is identical so the angle at the top of the other triangle will also be 130.

The sum of angles in a circle is 360.

Therefore, angle x = 360-(130x2)

X= 100

Solve the equation for t. (t-7)^2+18=9
Anika [276]

Answer:

t = 7 + 3i

Step-by-step explanation:

(t-7)^2 + 18 = 9

(t-7)^2 = 9 - 18

(t-7)^2 = -9

(t-7) = sqrt(-9) = |3| sqrt(-1)

t = 7 + 3i

Caleb bought groceries and paid \$1.60$1.60dollar sign, 1, point, 60 in sales tax. The sales tax rate is 2.5\%2.5%2, point, 5, p
saveliy_v [14]

Answer:

Price of Caleb's groceries before tax = $64

Step-by-step explanation:

Let the price of groceries before tax be =$ x

Sales tax charged = $1.60

Sales tax rate =2.5%

Sales tax charged in terms of x will be = 2.5% of the Original price of grocery =2.5\% of x = 0.025\times x=0.025x

So, we have,

0.025x=1.60

Dividing both sides by 0.025

\frac{0.025x}{0.025}=\frac{1.60}{0.025}

∴ x=64

∴ Price of Caleb's groceries before tax = $64
