Answer:
1,483 is the answer
Answer:
Step-by-step explanation:
Let's say Pedro got x hits
and Ricky got y hits.Given,Pedro and Ricky together got 2685 hits.So, the
equation will be as (x+y)=2685................eq (1)
Given,Pedro had 281 more hits than Ricky.So the equation looks like
x=281+y..........eq(2).
substitute eq(2) in eq(1).We get,
2685=(281+y)+y
2685=281+2y
2685-281=2y
2404=2y
2404/2=y
y=1202
substitute y=1202 in eq(2).We get,
x=1202+281
x=1483
So,Pedro hit 1483 and Ricky hit 1202

What is the surface area of the piece of cheese?
A. 14.5 square inches
B. 29 square inches
C. 32. square inches
As you can see in the diagram, the triangular prism has the following faces:
1) Two triangular faces
2) Three rectangular faces.
Surface area is the SUM of the areas of all of the faces.
Let us find these faces one by one:
1.
As you know, the area of the triangle is:
\(\frac{1}{2}* base*height\)
Since, the base = 6 inches, and height = 4 inches;
Therefore, The area of ONE triangle = (1/2) * 6 * 4 = 12 inches squared.
In triangular prism, there are two triangles, therefore,
Two triangular faces = 2 * 12 inches = 24 inches squared --- (A)
2.
Now let us find the areas of three rectangular faces...
Since, two of the three rectangular faces are the same, therefore, we would find the area of one rectangular face, and multiple the result with two to get the total area of two rectangular faces.
Area of one rectangular face = base * height.
Since, base = 0.5 inches, height = 5 inches, therefore,
Area of one rectangular face = 0.5 * 5 = 2.5 inches squared.
Now that we have one rectangular face, therefore,
Area of two rectangular faces = 2 * 2.5 = 5 inches squared.
The area of the third rectangular base = 6 * 0.5 = 3 inches squared
Therefore,
The area of the three rectangular faces = 5 + 3 = 8 inches squared --- (B)
Now add both "area of two triangular faces(A)" and "area of three rectangular faces(B)" to get the final surface area of the triangular prism.
Surface Area of the triangular prism = Area of Two Triangular faces + Area of Three Rectangular faces
Surface Area = 24 + 8 = 32 inches squared
The surface area of the triangular prism = 32 inches squared.

What is the perimeter of the rectangle?
Answer:
12
Step-by-step explanation:
Opposite sides of a rectangle share the same side measurements (based on the definition of a rectangle). This means that the perimeter is found as:
P(perimeter)= 2l + 2w
Let:
length (l) = 4
width (w) = 2
Plug in the corresponding numbers tot eh corresponding variables:
P = 2(l) + 2(w)
P = 2(4) + 2(2)
Simplify. First, multiply, then add:
P = (2 * 4) + (2 * 2)
P = (8) + (4)
P = 12
12 will be your perimeter.
~
Check. Since it is given that it is a rectangle, by definition of a rectangle, you will know that opposite sides are congruent, and therefore share the same measurements.
P = 2 + 2 + 4 + 4
P = (4) + (8)
P = 12
12 will be your perimeter.

The equation is,
→ 6r - 1 + 6r = 11
Now the value of r will be,
→ 6r - 1 + 6r = 11
→ 12r = 11 + 1
→ r = 12/12
→ [ r = 1 ]
Hence, the value of r is 1.

Answer:
Answer:
x= 29/11 or y= 25/11
Step-by-step explanation:
2x - y= 3 ...........equation 1
x + 5y= 14 ............equation 2
Make x the subject of the formula in equation 2
x= 14 - 5y ..............equation 3
Substitute x=14 - 5y in equation 1
2(14- 5y) - y=3
28 - 10y - y=3
Collect like terms
-10y - y=3 - 28
-11y= -25
divide both sides by coefficient of y
-11y/-11 = -25/-11
y= 25/11
Substitute y= 25/11 in equation 3
x=14 - 5(25/11)
x= 14 - 125/11
x= 29/11

Julia loves collecting baskets. Every month she adds two new baskets to her collection. In the month of March she has 60 baskets. She’s worried she will soon run out of room in her apartment to keep her baskets. Write an equation that represents the percent of change of her basket collection from the beginning of the year to the end of the year, then solve.
The linear function that represents the amount of baskets in the xth month of the year is given as follows:
The percentage of her collection that she needs to get rid of is of 3.85%.
Linear Function:-
The definition of a linear function is:
y = b + mx
In which the parameters of the equation are given as follows:
•b is the value of y when x=0
•m is the rate of change for each unit of x
Every month she adds 2 new baskets to her collection, hence the slope is of : m = 2
Then: y = b + 2x
From the March amount, when x = 3, y = 60, hence the intercept b is given as follows:
60 = b + 6
b = 54
Hence the equation is: y = 54 + 2x
At the end of the year (12 months) the amount of baskets that she will have is of:
y = 54 + 2 × 12 = 78
Hence, she has to get rid of 3 baskets, as 78 - 75 = 3, and the percentage is of:
p = 3/78 × 100% = 3.85%.

Answer:
3(16x+9)/4
make sure it's a fraction
Answer:
27 11/4x
Step-by-step explanation:
First we add the similar parts of the expression.
Whole numbers
6 + 9 + 5 + 7 = 27
Then we add the fractions that dont have x.
We only add the numerators (2 and 3) and dont change the denominators (4)
2/4 + 3/4 = 5/4
Now we add the ones with x.
5/4 + 3/4x + 3/4x = 11/4x
Now we combine those parts together, making
27 11/4x

(2/5)^8 x (2/5)^-2 / (5/2)^-7
The required answer is ⅖¹³.
Step-by-step explanation:Given terms to us is :-
\(=\bf \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{5}{2}^{-7}\)
We can see here that two terms have same base that is ⅖ . And the other is 5/2. So for simplifing the expression we will use some laws of exponents , which are :-
a ^m + aⁿ = a^{m + n }a -ⁿ = ( 1/a )ⁿUsing these we have ,
\(\bf = \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{5}{2}^{-7} \\\\\bf= \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{2}{5}^7 \\\\\bf= \bigg(\dfrac{2}{5}\bigg)^{(8+7-2)}\\\\\boxed{\red{\bf= \dfrac{2}{5}^{13}}}\)

A 16-inch pizza is cut into 8 equal slices. If she ate 3 slices, approximately how many square inches of pizza did she eat? approximately __ in.2
Answer:
6 inch^2
Step-by-step explanation:
16/8 = 2 inch^2 per slice
3 x 2 = 6 inch^2
The amount of square inches of pizza she ate is 75.398 inches².
What is Area?
Area of a two dimensional shape is the total region which is bounded by the object's shape.
Pizza is circular in shape.
Diameter of the pizza = 16 inches
Radius of the pizza = 16/2 = 8 inches
Area of the pizza = π r², where r is the radius
= 8² π
= 64π
Area of each slice if it is cut into 8 equal slices = 64π/8 = 8π
If she ate 3 slices,
Area of 3 slices = 3 × 8π = 24π = 75.398 inches²
Hence the area of the pizza that she ate is 75.398 inches².

thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).

We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
