Salim and Anna met when they were in first grade, and they have been best friends for 10 years. Which part of this sentence is a clause?
Here, we are required to identify which part of the sentence is a clause .
The clause in the sentence is "Salim and Anna met when they were in first grade"
First, we must know that a clause is simply defined as a group of words containing a subject and predicate and functions as a part of a complex or compound sentence.
The sentence "Salim and Anna met when they were in first grade, and they have been best friends for 10 years." is a compound sentence.
And, the "Salim and Anna met when they were in first grade" part of the sentence is a clause as it has a subject which is "Salim and Anna" and a predicate which is the rest of the sentence i.e "met when they were in first grade"
The part of the sentence which is a clause is Salim and Anna met when they were in first grade

What is geometry?Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial properties such as figure distance, shape, size, and relative position.
Given that a box with no top that has a volume of 1000 cubic inches is to be constructed from a 22 x 30-inch sheet of cardboard by cutting squares of equal size from each corner and folding up the flaps.
The size of the square cut from each corner will be calculated as,
Volume = L x H x W
1000 = 22 x 30 x H
H = ( 1000 ) / ( 660 )
H = 1.538 or 1.369 inches
Therefore, the size will be 1.369 inches.

Answer:
Temperature at 9 A.M = 13° F
Step-by-step explanation:
Given:
Temperature at 6 A.M = - 2° F
Temperature increases in 3 hours = 15° F
Find:
Temperature at 9 A.M
Computation:
Temperature at 9 A.M = Temperature at 6 A.M + Temperature increases in 3 hours
Temperature at 9 A.M = - 2° F + 15° F
Temperature at 9 A.M = 13° F

Answer:
report that dude the answer is:
-7.75
Step-by-step explanation:
(1/2)^2 - 6(2 - 2/3)
First we get rid of the exponent 2 by muliplying the (1/2) two times.
(1/2)×(1/2) = 1/4
Now we have:
1/4 - 6(2 - 2/3)
Now we solve the equation in the other paraenthesis:
(2 - 2/3) = 1 1/3
Now we plug it back in:
1/4 - 6(1 1/3)
Now we mulitply the 6 with the fraction 1 1/3 in the paraenthesis:
6(1 1/3) = 8
Now we plug it back in:
1/4 - 8
Now finally solve this fraction:
-7.75

Answer: $2800
Step-by-step explanation:
if the function is f(x) and shes already saved $1000 plug in the functions, or in other words plug in x for weeks.
1000 + 150 x
(plug in x)
1000 + 150 x 12

Out of the 400 students in a final year in secondary school, 300 are offering biology and 190 are offering chemistry. I) how many student are offering both subject , if only 70 students are offering neither biology nor chemistry? I) how many students are offering at least one biology and chemistry?
Answer:
I) how many student are offering both subject , if only 70 students are offering neither biology nor chemistry?
= 160 students
II) how many students are offering at least one biology and chemistry?
= 330 students
Step-by-step explanation:
I) how many student are offering both subject , if only 70 students are offering neither biology nor chemistry?
Total number of student n ( B ∪ C) = 400
Students offering biology n(B) = 300
Students offering chemistry n(C) = 190
Students not offering biology nor chemistry = 70
Students offering both biology and chemistry n ( B ∩ C) = ??
n ( B ∪ C) - Students neither offering biology nor chemistry = n(B ) + n ( C ) - n ( B ∩ C)
400 - 70 = 300 + 190 - n ( B ∩ C)
330 = 490 - n ( B ∩ C)
n ( B ∩ C) = 490 - 330
n ( B ∩ C) = 160
Therefore, students offering both Biology and Chemistry are 160 students.
II) how many students are offering at least one biology and chemistry?
n(B' ) + n ( C') + n ( B ∩ C)
n(B') = Students offering biology only
= n(B) - n ( B ∩ C)
= 300 - 160 = 140
n(C') = Students offering chemistry only
n(C) - n ( B ∩ C)
= 190 - 160
= 30
(300 - 160) + (190 - 160) + 160
140 + 30 + 160
= 330 students

The perimeter of a right triangle is 25 meters and the area is 20 square meters. The length of the sides are each multipled by 3. What is the are of the new triangle
Answer:
The area of the new triangle is 180 m²
Step-by-step explanation:
let the height of the triangle = h
let the base of the triangle = b
The area of right triangle is given by;
A = ¹/₂bh
20 = ¹/₂bh
If we multiple each side of the triangle by 3, the new area of the triangle will be as follows;
A= ¹/₂(3b)(3h)
A = ¹/₂(9) (bh)
A = 9(¹/₂bh)
A = 9(20)
A = 180 m²
Therefore, the area of the new triangle is 180 m²

A truck parked on the street is 56 m from the base of the apartment building on the right. The angle of elevation from the truck to the top of the building is 40°. The parked truck is 49 m from the base of the apartment building on the left. The angle of elevation from the truck to the top of that building is 50°. Which building is taller?
Answer:
The taller building is the second building which is the apartment building on the left with an height of 58.4m
Step-by-step explanation:
This is a Trigonometric question. We solve this using the Tangent formula
tan θ = Opposite side/Adjacent side
We are given 2 buildings
Building 1
tan θ = Opposite side/Adjacent side
θ = Angle of Elevation = 40°
Distance from the base of the building = Adjacent = 56m
Height of the building = Opposite side = unknown
tan 40 = 0pposite/56m
Opposite = tan 40 × 56m
Opposite = 46.989579346m
Approximately = 47m
Height of Building 1 = 47m
Building 2
tan θ = Opposite side/Adjacent side
θ = Angle of Elevation = 50°
Distance from the base of the building = Adjacent = 49m
Height of the building = Opposite side = unknown
tan 50 = 0pposite/49m
Opposite = tan 50 × 49m
Opposite = 58.395926037m
Approximately = 58.4m
Height of Building 2 = 58.4m
The taller building is the second building which is the apartment building on the left with an height of 58.4m
