Is the value of the first 7 ten times as great as the value of the second 7 in 7237
Answer:
no
Step-by-step explanation:
Part way through painting her room, Sam runs out of paint.
• She estimates that there are about 125 square feet left to paint.
• The purple paint that Sam is using is only available in 1-quart
cans. (Assume she must buy whole cans of paint.)
• Each can of paint covers 40 square feet.
How many cans of paint does Sam need to buy to finish painting her room?
Explain to Sam why she needs this many cans of paint.
Answer:
4
Step-by-step explanation:
You divide 125 by 40 and that will give you 3 1/8. In the question, it says to use whole numbers and you'd have to go up, giving you 4.
It takes you together 6.67 minutes to paint 50 square feet, as you have to consider that the together rate is the sum of the separate rates.
What is addition?Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
The together rate is the sum of the separate rates.
In this question:
Sam's rate is 1/10 for 25 square feet, so 1/20 for 50 square feet.
Your's rate is 1/5 for 25 square feet, so 1/10 for 50 square feet.
Together rate:
1/x = 1/20 + 1/10
or, 1/x = 3/20
or, x = 20/3
or, x = 6.67
so, we get,
It takes you together 6.67 minutes to paint 50 square feet, as you have to consider that the together rate is the sum of the separate rates.

12 people can fit in a room that is 9 feet by 4 feet. How many people will fit in a room that is 6 yards by 6 yards
Answer:
Number of people fit in 6 feet by 6 feet room = 12 people
Step-by-step explanation:
Given:
Number of people fit in 9 feet by 4 feet room = 12 people
Find;
Number of people fit in 6 feet by 6 feet room
Computation:
Surface area of 9 feet by 4 feet room = 9 x 4
Surface area of 9 feet by 4 feet room = 36 feet²
So,
Surface area of 6 feet by 6 feet room = 6 x 6
Surface area of 6 feet by 6 feet room = 36 feet²
Surface area of both rooms are equal. so number of people are also equal
Number of people fit in 6 feet by 6 feet room = 12 people

sasha needs 3/4 cup of flour to make a batch of muffins and 1 2/3 cups of flour to make loaf of bread. How many cups of flour does sasha need to make both a batch of muffins and a loaf of bread
Using the addition operation, the number of cups of flour Sasha needs to make both a batch of muffins and a loaf of bread is 2⁵/₁₂ cups.
How is the number or quantity determined?We can use the addition operation to determine the quantity of flour that Sasha needs.
We add the cups of flour needed for both items to determine the total quantity.
The quantity of flour for making a batch of muffins = 3/4 cups
The quantity of flour for making a loaf of bread = 1²/₃ cups
The total quantity of flour needed for making a batch of muffins and a loaf of bread = 2⁵/₁₂ cups (³/₄ + 1²/₃)
(³/₄ + 1²/₃)
= ³/₄ + ⁵/₃
= (9 + 20)/12

Find C. Give your answer in the simplest form.
Using the pythagoras theorem in the given figure, the required length of c is [tex]49\sqrt{6}[/tex].
What is pythagoras theorem?The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagorean Theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides.
Who is pythagoras theorem named after?The pythagoras theorem is named after the Greek mathematician-philosopher Pythagoras.
To solve for c, first taking the small triangle in the left of the figure,
since one of the angle is 45 degree and another is 90 degree, the unlabelled angle is 45 degree. Which makes this triangle a isosceles triangle, hence the sides a and b are equal in length. i.e a = b
Using pythagoras theorem in this triangle,
[tex](7\sqrt{2} )^{2} = \sqrt{a^{2}+\ a^{2} }[/tex]
Therefore, a = 49[tex]\sqrt{2}[/tex]
Now Taking the small triangle in the right of the given figure,
tan 30 = a/c
or, [tex]\frac{1}{\sqrt{3} }[/tex] *c = 49[tex]\sqrt{2}[/tex]
Therefore , c = 49[tex]\sqrt{6}[/tex]

What is the triangle?Given that it has three sides and three vertices, a triangle qualifies as a polygon. It is a fundamental geometric figure. Triangle ABC is the term used to refer to a triangle containing the vertices A, B, and C. When the three points are not collinear, a unique plane and triangle in Euclidean geometry are discovered. Triangles are polygons because they have three sides and three corners. The points where the three sides of the triangle converge are referred to as the triangle's corners. Three triangle angles are multiplied to yield 180 degrees.
Here,
Given : Height of drone = 5 feet
and distance of drone covered is 12 feet
Thus ,
to calculate the distance of the drone from the start point
distance can be represented as H

Establish a perimeter.The perimeter, or total length, of a shape is referred to as its perimeter in geometry. A shape's perimeter is calculated by summing the lengths of all of its sides and edges. By adding together the lengths of all a shape's sides, one may determine its perimeter. The circumference of a field, for instance, will be 78 yards for a rectangle with dimensions of 24 yards long by 15 yards wide.
Here,
Given : PQRS has the length 12
and TUVW has length 15.

To find the perimeter of PQRS:
we find,
TUVW = 35 units
and
PQRS = 35 - 6
=> PQRS = 29

Figures A and b are similar. Figure A has an area of 18 square feet. Figure b has an area of 98 square feet and one of the sides lengths is 14 feet find the corresponding side length
Answer:
6 ft
Step-by-step explanation:
The ratio of the square of the sides of two similar figures = the ratio of their area
Let x represent the missing side corresponding side length
Therefore,
Area of figure B/area of figure A = square of side length of figure B/square of the side length of figure A
Thus:
98/18 = 14²/x²
98/18 = 196/x²
Cross multiply
98*x² = 196*18
98x² = 3,528
Divide both sides by 98
x² = 3,528/98
x² = 36
x = √36
x = 6
Therefore, missing corresponding side length = 6 ft
The corresponding side length is 2.57 feet
Similar shapesGiven that figures A and b are, hence the ratio of the area to the length is equal to a constant as shown:
[tex]\frac{A}{L} = \frac{a}{l}[/tex]Substitute the given parameters into the formula to have:
A = 98 square feet
L = 14 square feet
a 18 square feet

Answer: 28 children
What is a ratio?A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare the numbers, and you can compare them using division.
First, we would need to figure out the total number of students. To do this, we can divide 84 by 3, then add that to the total.
84 ÷ 3 = 28
28 + 84 = 112
This means that there are 112 students in the classroom.
If 3/4 of the children in the school have blue eyes, we know that 1/4 of the children will have brown eyes. We can convert 1/4 into a decimal, or into a percentage, to get the number of children with brown eyes.
1/4 = 0.25 = 25%
To figure out how much 25% of 112 is, we can simply multiply 112 by 0.25.
112 × 0.25 = 28
So, this means that there are 28 children with blue eyes in the school.
