3. The material Santiago will use to build the ramp costs $2.20 per square foot. What will the total cost of building the ramp be?
Answer:
262 square feet
Step-by-step explanation:
The required expression model for the cost of the ramp is y = 2.20x.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Let the area of the ramp be x and the cost to build the ramp be y,
According to the question,
The material Santiago will use to build the ramp costs $2.20 per square foot.
Total cost = 2.20 × area of the ramp
Substitute the variable in the above expression,
y = 2.20x
The above equation represents the equation model for the cost of ramp y for the x square foot area of the ramp.
Thus, the required expression model for the cost of the ramp is y = 2.20x.

When factoring an expression, how can you tell if you used the GCF as the factor? Explain.
Answer:
LARGEST FACTOR
Step-by-step explanation:
The greatest common factor or GCF is the largest factor that all terms have in common. Step 2: Factor out (or divide out) the greatest common factor from each term. Step 1: Determine the greatest common factor of the given terms. The greatest common factor or GCF is the largest factor that all terms have in common.
44 cu. cm of wire is drawn into a wire of diameter 2 mm , the length of wire will be _____.
Given:
44 cu. cm of wire is drawn into a wire of diameter 2 mm.
To find:
The length of the wire.
Solution:
We know that,
1 cm = 10 mm
1 cu. cm = 1000 cu. mm
We have, a wire of cylindrical shape.
Volume of the wire = 44 cu. cm
= 44000 cu. mm
Radius of the wire = 2 mm
Volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
Where, r is the radius and h is the height.
Putting V=44000, [tex]\pi=\dfrac{22}{7}[/tex] and r=2, we get
[tex]44000=\dfrac{22}{7}\times 2^2\times h[/tex]
[tex]44000\times \dfrac{7}{22}=4h[/tex]
[tex]14000=4h[/tex]
Divide both sides by 4.
[tex]\dfrac{14000}{4}=h[/tex]
[tex]3500=h[/tex]
Therefore, the length of the wire is 3500 mm or 350 cm.

Igneous rock is formed through heat and pressure.
Sedimentary rocks usually form beneath the Earth's crust.
The rock cycle starts with sedimentary rock and ends with igneous rock.
Sedimentary rocks usually form in visible layers.
Answer:
Sedimentary rocks usually form in visible layers
Step-by-step explanation:
A is wrong because not all igneous rock is formed by pressure
B is wrong because sedimentary rock is usually a surface rock
C is wrong because the rock cycle is sporadic and doesn't always end in igneous rock

A plane intersects the center of a sphere
with a volume of about 9,202.8 m3. What is
the area of the cross section? Round to the
nearest tenth.
Answer:
530.66
Step-by-step explanation:
The computation of the area of the cross section is shown below
Given that
Volume = 9208 m^3
Now let us assume the radius be r
So volume = 4 ÷ 3 πr^3
9202.8 × 3 ÷ 4π = r^3
27,608.4 ÷ 4 × 3.14 = r^3
27,608.4 ÷ 12.56 = r^3
2,198.12 = r^3
r = 13
Now the area of the cross section is
= πr^2
= 3.14 × (13)^2
= 530.66
Max typically drinks 3 3/4 cups of milk each day. Today he tripled that amount.
How much milk did Max drink today?
Answer:
11 1/4
Step-by-step explanation:
Multiply this by three, 3, 6, 9.
3/4, 1 2/4, 2 1/4.
2 + 9 = 11.
11= 1/4 = 11 1/4
Answer:
Max drank 11 1/4 cups of milk today.
Explanation:
Convert the mixed number (3 3/4) to a fraction.
Then your equation becomes:
15/4 x 3/1 (since he tripled the cups of milk he drank you multiply by 3 which as a fraction is 3/1)
Next:
15/4 x 3/1= 11 1/4!

Need help plzzz will give Brainlyest
Answer:
Rate = 4%
Step-by-step explanation:
Simple interest = (principal × rate × time) / 100
Principal = $399.00
Rate = ?
Time = 2 years
Interest = $31.92
Simple interest = (principal × rate × time) / 100
31.92 = (399 * x * 2) / 100
31.92 = 798x / 100
Cross product
31.92 * 100 = 798x
3192 = 798x
x = 3192 / 798
x = 4%
Rate = 4%

A triangle has side lengths of 1.9cm, 2.7cm and 3.3cm, all measured to 1 decimal place could this be a right angled triangle
Answer:
Yes
Step-by-step explanation:
A triangle is a "right" triangle if its lengths fullfil the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
Here, a and b are the shorter "legs" of the triangle, adjacent to its right angle, while c is the "hypotenuse," the longest side and the one opposite the right angle.
If we call the 1.9 cm and 2.7 cm our legs, the sum of their squares is:
[tex]2.7^2+1.9^2=10.9[/tex] cm
While squaring our hypotenuse gives us
[tex]3.3^2=10.89[/tex] cm
The fact that we measured the triangle's side lengths to 1 decimal point of accuracy means that there's a little margin of error baked into the measurement. The two previous calculations are within 0.01 cm of each other, which is more than close enough, so we can say that yes, this could be a right triangle.
Maxine find a dress on sale for 10% off at a boutique.The original price was $62, Maxine must also pay 6.75% sales tax.What is the final cost of the dress?
10% off means she pays 90% of the original price. (100% - 10% = 90%)
62 x 0.90 = 55.80 the sale price of the dress is $55.80
Now add the tax by multiplying the sale price by 1 + tax rate:
55.80 x 1.0675 = 59.57
She paid $59.57
Answer:
10% off means she pays 90% of the original price. (100% - 10% = 90%)
62 x 0.90 = 55.80 the sale price of the dress is $55.80
Now add the tax by multiplying the sale price by 1 + tax rate:
55.80 x 1.0675 = 59.57
She paid $59.57

The perimeter of a rectangular field is 84 yards. The ratio of the length to the width is 2:1. What are the length, width and area of the field?
Given:
the perimeter of a rectangular field is 84 yardsthe ratio of the length to the width is 2:1To find:
the lengththe widththe areaAnswer:
Let's assume that the length is 2x and the width is 1x.
We know that the formula to find the perimeter of a rectangle is as follows:
Perimeter = 2 × (Length + Width)
Substituting the values that we have, into the formula above,
84 = 2 × (2x + 1x)
84 = 2 × 3x
84/2 = 3x
42 = 3x
x = 42/3
x = 14
Since we know the value of 'x', let's use it to find the length and the width.
Length = 2x = 2 × 14 = 28
Width = 1x = 1 × 14 = 14
Since we now know the length and the width, let's find the area of the rectangle.
The formula to find the area of a rectangle:
Area = Length × Width
Substituting the values we have into the formula,
Area = 28 × 14
Area = 392
Therefore, the area of the rectangle is 392 square yards.
