Answer:
4(4)
Step-by-step explanation:
1.25 (4(4) - 10) = 7.5
1.25(16 - 10) = 7.5
1.25(6) = 7.5
1.25 + 1.25 = 2.5 + 2.5 = 5 + 2.5 = 7.5
1 + 1 = 2 + 2 = 4 + 2 = 6
An equation is formed of two equal expressions. The value of x that will make the given equation true is 4.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The value of x that makes the equation true can be found by finding the value of x in the given equation. Therefore, the value of x is,
1.25(4x - 10) = 7.5
Multiply 1.25 inside the parenthesis,
5x - 12.5 = 7.5
Add 12.5 on both sides of the equation,
5x - 12.5 + 12.5 = 7.5 + 12.5
5x = 20
Divide both sides of the equation by 5,
5x/5 = 20/5
x = 4
Hence, the value of x that will make the given equation true is 4.

Find a single expression that represents the surface area of the rectangular prism
The single expression that represents the surface area of the rectangular prism is :
S= 2lw + 2lh + 2wh
Let us assume the l is length, width is w and h is the height of the rectangular prism.
What is the rectangular prism?
In geometry, a rectangular prism can be stated as a 3-dimensional solid shape that has 6 faces with its base as rectangles.
So, the surface area S would be :
S = surface area
S= 2lw + 2lh + 2wh
where,
l= length
w= width
h = height
Therefore, the surface area of the rectangular prism is :
S= 2lw + 2lh + 2wh

A baker is making walnut bread. The recipe uses 2/3 cups of walnuts for each bread recipe. The baker has 7 1/2 cups of walnuts. What is the maximum numbers of full recipe of walnut bread the baker can make?
Answer:
11 breads
Step-by-step explanation:
Note that:
1 bread recipe = 1 bread
From the above question, we know that:
2/3 cups of walnut = 1 bread
7 1/2 cups of walnut = x breads
Cross Multiply
2/3 cups × x breads = 7 1/2 cups × 1 bread
x breads = 7 1/2 cups × 1 bread/2/3 cups
x breads = 7 1/2 ÷ 2/3
x breads = 15/2 ÷ 2/3
x breads = 15/2 × 3/2
x breads = 45/4
x breads = 11 1/4 breads
Maximum full recipe = 11 breads.
Therefore, the MAXIMUM numbers of full recipe of walnut bread the baker can make is 11 breads.
Two sides of a triangle measure 7 feet and 19
feet. Write an inequality to represent the range
of lengths for the third side.
Answer:
12<x<26
Step-by-step explanation:
7 + 19 = 26
19 - 7 = 12
Always put the larger number before the smaller one while subtracting like I just did.
The inequality to represent the range of lengths for the third side as
{x} < 26.
What is a triangle?A triangle is a two - dimensional figure with three sides and three angles.
The sum of the angles of the triangle is equal to 180 degrees.
∠A + ∠B + ∠C = 180°
Given is that two sides of a triangle measure 7 feet and 19 feet.
It is aske to write an inequality to represent the range of lengths for the third side. It is given that two sides of a triangle measure 7 feet and 19 feet.
For a inequality, the sum of the lengths of the two smaller sides is greater than the length of the maximum side. So, write an inequality to represent the range of lengths for the third side as -
19 + 7 > x
x < 19 + 7
x < 26
So, we can conclude that the inequality to represent the range of lengths for the third side as {x} < 26.
Therefore, the inequality to represent the range of lengths for the third side as {x} < 26.

Complete question :
The average daily volume of a computer stock in 2011 was p = 35.1 million shares, according to a reliable source. A stock analyst believes that the stock volume in 2014 is different from the 2011 level. Based on a random sample of 40 trading days in 2014, he finds the sample mean to be 30.9 million shares, with a standard deviation of s = 11.8 million shares. Test the hypotheses by constructing a 95% confidence interval. Complete parts (a) through (c) below. State the hypotheses for the test. Construct a 95% confidence interval about the sample mean of stocks traded in 2014.
Answer:
H0 : μ = 35.1 ;
H1 : μ < 35.1 ;
(26.488 ; 35.312)
Step-by-step explanation:
The hypothesis :
H0 : μ = 35.1
H1 : μ < 35.1
The confidence interval :
Xbar ± Margin of error
Xbar = 30.9
Margin of Error = Zcritical * s/sqrt(n)
Zcritical at 95% = 1.96
Margin of Error = 1.96 * (11.8/sqrt(40))
Margin of Error = 4.412
Lower boundary :
30.9 - 4.412 = 26.488
Upper boundary :
30.9 + 4.412 = 35.312
Confidence interval = (26.488 ; 35.312)
Since the population mean value exists within the interval, the we fail to reject the Null.

After the community clean up, the ecology club collected all the empty drink containers. There were 40 more 5 cent deposit containers than 10 cent deposit containers. If the club received $24.80 from the recycling center, how many 5 cent deposit containers did they have?
The number of 5-cent deposit containers the ecology club collected is 192.
What are the linear equations that represent the question?a - b = 40 equation 1
0.05a + 0.1b = $24.80 equation 2
Where:
a = number of 5-cent deposit containers b = number of 10- cent deposit containers.How many 5-cent deposit containers were collected?
The first step is to multiply equation 1 by 0.1
0.1a - 0.1b = 4 equation 3
Add equation 3 and equation 1
$28.80 = 0.15a
a = $28.80 / 0.15
a = 192

Find the surface area
Answer
96
Step-by-step explanation:
Answer:
96m
Step-by-step explanation:
Surface area of a pyramids formula is SA= B+1/2*l*P
B= area of base
l= slant height
P= perimeter of base
B= 6*6= 36
l= 5
P= 6+6+6+6 = 12+12 = 24
plug them into the formula
SA= (36)+1/2 * (5)*(24)
SA = (36)+1/2* 120 ------------- do 5 * 24
SA= (36) + 60 -----------do 120/2
SA = 96

Perimeter of triangle: 16 in.
Answer:
x= 16/3
Step-by-step explanation:
From the equation we know x is the same for all sides so the perimeter is:
p = x + x+ x we know the perimeter so it would be
16 = 3x (we add the x)
then we need to divide both sides by three to have an equation for x so it would be:
x= 16/3
