Answer:
hmmm not sure
Step-by-step explanation:
try mulitply the numbers
Answer:
4
Step-by-step explanation:
she can use all 63 beads because 67 divided by 9 is 7 remainder 4
I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250
250+120=370!!
answer : 370 kilometers per hour
Answer:
240 people
Step-by-step explanation:
According to the given data,
In each bus,there are total number of 36 students and 4 adults
So, total 40 people are in one bus so...
As, there are six Fields buses
=>40 x 6
=240
Answer: Total 240 people are going on the field trip.
Answer:
∠1 = 50°
∠2 = ∠3 = 130°
Step-by-step explanation:
In an isosceles trapezoid, such as this one, the angles at either end of a base are congruent:
∠1 ≅ 50°
∠2 ≅ ∠3
The theorems applicable to transversals and parallel lines also apply to the sides joining the parallel bases. In particular, "consecutive interior angles are supplementary." That is, angles 1 and 2 are supplementary, for example.
∠2 = 180° -∠1 = 180° -50° = 130°
We already know angle 3 is congruent to this.
∠1 = 50°
∠2 = ∠3 = 130°

<em>Additional comment</em>
It can be easier to see the congruence of the base angles if you remove the length of the shorter base from both bases. This collapses the figure to an isosceles triangle and makes it obvious that the base angles are congruent.
Alternatively, you can drop an altitude to the longer base from each end of the shorter base. That will create two congruent right triangles at either end of the figure. Those will have congruent corresponding angles.
