a rectangle is 40cm long and 30cm wide, use a scale of 1cm to represent 10cm to draw a scale diagram of the rectangle on the grid.
Hello mariamhifzur!
Given,
A rectangle is 40 cm long & 30 cm wide. So,
Length = 40 cmWidth = 30 cmNow, using a scale of 1 cm to represent 10 cm we need to draw a scale diagram of the rectangle on the grid.
At first we need to convert the measurements of the rectangle in real life to its scale measurements. In the question given, we need to convert 10 cm to 1 cm in the scale. So,
Length = 40 cm = 4 cm (in the scale figure)Width = 30 cm = 3 cm (in the scale figure)Now, suppose each grid is equal to 1 cm. Then, we can take the measurements as :
Length = 4 cm = 4 boxes/gridsWidth = 3 cm = 3 boxes/gridsLet's draw the figure now. Our rectangle looks like ... (see the attachment).

3 Write a numerical expression to model the words. Subtract 1 from the product of 4 and 5.
Answer:
Hello!
After reading the question you have provided I have come up with the correct numerical expression:
4x5-1
Step-by-step explanation:
To come up with this solution you need to keep in mind some of the terminoloy being used.
The word "subtract" comes from the action of subtraction
The word "product" comes from the action of multiplication
Thus, using those terminologies correctly, you can then deduce that when the question says "the product of 4 and 5" means "multiplying 4 and 5 together".
So you get the first part being 4x5
Then, you add in the last part of "subract 1" from the "product of 4 and 5":
4x5-1
Remember to keep in mind the rule of "PEMDAS"
You always need to keep the multiplication portion of the equation in front of any subtraction, or addition in any given equation.
Here to form the numerical expression we will first do the product of 4 and 5 and then subtract 1 from their resultant and that is ou required answer.
What is numerical expression ?A numerical expression is written in terms of numbers and their operations numerical expression can of many types for example arithmatic expression , alzebraic expression etc.
some examples of arithmatic operations are -
240+130 = 370
240÷12 = 20
Some examples of alzebraic expressions are
3x + 4y = 7
x² + 3x - 7 = 0
In the given question subtract 1 from the product of 4 and 5 can be expressed as (4x5) - 1 = 20 - 1 = 19

You didn't really describe what we're supposed to do, but I'm going to assume they want you to graph it.
The first equation has a slope of 3/5x, meaning that for every 3 units it moves upwards, it moves right 5 units. It has a y-intercept of 8, meaning that the line will cross through (0, 8) on the coordinate plane. Start your point on (0, 8) and draw a line that goes up 3 units and 5 units.
The second equation has a slope of -4/5x, meaning that for every 4 units it moves upwards, it moves left 5 units OR for every 4 units it moves down it moves 5 units right. The y-intercept is 1, so the line will go through (0, 1). Start your point on (0, 1), and draw a line that follows the slope, just like last time.
If this is all correct and the best answer, please give me brainliest as I'm trying to rank up. Thanks!

a boat is 180 in Long in private plane is 85% longer than the boat how long is the plane
Answer:
The length of the plane is 333 in.
Step-by-step explanation:
Plane length = (1.85)(Boat length)
The 0.85 in (1.85) above represents the added length; the (1.85) represents the length of the boat PLUS 0.85 time the length of the boat.
Plane length is (1.85)(Boat length) = 1.85(180 in) = 333 in
The length of the plane is 333 in.

in a class there are 48 students the number of the girls is 3 times how many boys and girls are in class
Answer:
There are 12 boys and 36 girls.
Step-by-step explanation:
This equation should help explain it.
x + 3x = 48
Let's say that there are an x number of boys. Then there would be 3 times x of girls. So x (the boys) plus 3x (the girls) equal 48 (the total amount of students).
To solve this equation, first add x and 3x to get 4x. Then divide that by 48, and we get x = 2.
The amount of boys = x, so there are 12 boys.
The amount of girls = 3x, so there are 3 times 12, or 36 girls.
Mr and Mrs Smith buy tickets for themselves and 4 children
The cost of an adult ticket is £6 more than the child ticket
The total cost of the 6 tickets are £40.50
What is the cost of an adult ticket?
Answer=
$10.75 is the cost of an adult ticket
Answer:
£10.75
Step-by-step explanation:
6 tickets=£40.50
cost of adult=£6 more than a child's
let's form an equation!
x is the cost of children tickets and since we have 4 of them it leaves us with 4x. And an adult ticket is £6 more than a child's, so that leaves us with 6+x. And since we have 2 of them we get 2(6+x). So with this info, we can make an equation and solve it to find x:
2(6+x)+4x=40.50
12+2x+4x=40.50
12+6x=40.50
6x=28.50
x=4.75=the cost of a child ticket
adult ticket =£10.75

A ball is projected upward from ground level. After (t) seconds, its height in feet is
given by the function “h(t) = -16(t)^2 + 112(t)” After how many seconds will the ball reach a height of 192 ft for the first time?
Answer: 3 seconds
Step-by-step explanation:
h(t) = -16(t)^2 + 112(t)
Set h(t) = 192 feet
192 = -16(t)^2 + 112(t)
0 = -16(t)^2 + 112(t) - 192
Solve using the quadratic formula: There are two solutions, 3 and 4 seconds. Three seconds is the first time it reachers 192 feet, At four seonds it's on its way down.
The function can also be graphed (attached).

Identify one point and the slope from the equation y + 4 = 1/3(x - 1)
A. m = 4 Point = (1/3, 1)
B. m = 1/3 Point = (1,-4)
C. m = 1/3 Point = (1, 4)
D. m = 1/3 Point = (-1, 4)
Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
y + 4 = [tex]\frac{1}{3}[/tex] (x - 1) ← is in point- slope form
with m = [tex]\frac{1}{3}[/tex] and (a, b ) = (1, - 4 ) → B

2. The number of male teachers is 2/3 of the number of female teachers in a school. If there are 75 teachers altogether, how many more female teachers than male teachers are there?
Answer:
15
Step-by-step explanation:
Because the male teacher number is 2/3 of the female teachers, we can count the female teacher number as 3/3. and since we have a ratio of 2/3 to 3/3 we can take out the 3 and think of it as 2 to 3. Since it is 2 to 3, we have 5 in total and you can divide 75 by 5 which will get you 15 (how many teachers per unit in the ratio) and if you multiply 15 by 2, you will get the male teacher number which is 30, and when you multiply 15 by 3, you will get the female teacher number which is 45, and when you subtract them, you will get 15 more female teachers.
Hope it helped!
There are 15 more female teachers than the male teachers.
What is equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
Given that, The number of male teachers is 2/3 of the number of female teachers in a school and there are 75 teachers altogether,
Let there be 6x female and 4x male teachers in the school,
Establishing the equation,
6x + 4x = 75
10x = 75
x = 7.5
Number of more females = 6x-4x = 2x = 2(7.5) = 15
Hence, there are 15 more female teachers than the male teachers.
