Solve x + 7.8 = 11.9 for x.
Answer:
4.1
Step-by-step explanation:
X+ 7.8 = 11.9
X= 11.9 - 7.8
X= 4.1
Answer:
x = 4.1
Step-by-step explanation:
To solve for x, subtract 7.8 from both sides of x + 7.8 = 11.9:
x + 7.8 - 7.8 = 11.9 - 7.8, or
x = 4.1

In this figure shown, EF is the mid segment of trapezoid ABCD. Find EF.
Answer:
x = 2
Step-by-step explanation:
EF = ½(BC + AD) => Trapezoid Midsegment theorem
Substitute
5x + 4 = ½((4x + 1) + (7x + 5))
5x + 4 = ½(4x + 1 + 7x + 5)
Multiply both side by 2
2(5x + 4) = 4x + 1 + 7x + 5
10x + 8 = 4x + 1 + 7x + 5
10x + 8 = 11x + 6
Collect like terms
10x - 11x = -8 + 6
-x = -2
Divide both sides by -1
x = 2

A scale of 1 cm to 8 km is used for a map.
(i) If a forest has an area of 5 cm² on the map, find its actual area.
(ii)
If the actual area of a park is 128 km², calculate its area on the map.
Answer:
40 km^2
16 cm^2
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Actual area = scale factor x scaled area
8 x 5 = 40 km^2
Scaled area on the map = 128.8 = 16 cm^2
Jenny used plastic cone shaped cups to serve punch. The cups were 6 inches in diameter and inches tall. What was the volume of each cup?
Answer:
47.14 in³
Step-by-step explanation:
Here is the complete question
Jenny used plastic cone shaped cups to serve punch. The cups were 6 inches in diameter and 5 inches tall. What was the volume of each cup?
Volume of a cone = [tex]\frac{1}{3}[/tex]πr²h
π = 22/7
Radius = diameter / 2 = 6 /2 = 3 inches
(1/3) x (3^2) x (22/7) x 5 = 47.14 in³
A sports team is selling circular patches for their fans. Each patch has a
diameter of 9 centimeters. What is the area covered by the patch?
Round to the nearest hundredth, and use
3.14
Answer: 63.59cm²
Step-by-step explanation:
The area covered by the pitch will be gotten by finding the value of the area of the circle and this will be:
Area of q circle = πr²
where,
π = 3.14
r = radius = diameter/2 = 9cm/2 = 4.5cm
Area = πr² = 3.14 × 4.5²
= 3.14 × 20.25
= 63.59cm²
Therefore, the area covered by the pitch is 63.59cm²
John’s Rectangle is _____ units long.
John’s Rectangle is _____ units wide.
The area of John’s rectangle is ____ units^2.
Answer:
John's rectangle is 4 units long
John's rectangle is [tex]3\frac{1}{2}[/tex] units long
The area of John's rectangle is 14 units^2
Step-by-step explanation:
A rectangle has four sides that comprise of two pairs of equal length sides
The side which is the longest side of a rectangle is known as the length, L, of the rectangle
The side which is the shortest side of a rectangle is known as the width, W of the rectangle
Based on the given measurement, the length of the given rectangle which is the length of longest side of the rectangle, which is the 4 units length side
Therefore;
∴ John's Rectangle is L = 4 units long
the width of the given rectangle which is the length of shortest side of the rectangle, which is the side with lengths 3 units and 1/2 units length side
∴ The length of the shortest side of the rectangle, W = 3 units + 1/2 units = 3 1/2 units
∴ John's rectangle is W = [tex]3\frac{1}{2}[/tex] units wide
The area of John's rectangle, A = L × W
∴ The area of John's rectangle, A = 4 units × [tex]3\frac{1}{2}[/tex] units = 14 units².
help can you guys help me ill like eany coment and the answer
Answer:
The first step is false because the tub was not higher at 10:14 than at 10:01, The second box is true, because it is staying the same. The Third box is most likely true. The forth one is false , as there is a decline at 10:20 and the last one I am pretty sure is true also.

State study on labor reported that one-third of full-time teachers in the state also worked part-time at another job. For those teachers, the average number of hours worked per week at the part-time job was 13. After an increase in state teacher salaries, a random sample of 400 teachers who worked part-time at another job was selected. The average number of hours worked per week at the part-time job for the teachers in the sample was 12.5 with a standard deviation of 6.5 hours. Is there convincing statistical evidence, at the level of α=0.05, that the average number of hours worked per week at part-time jobs decreased after the salary increase?
(A) No. The p-value of the appropriate test is greater than 0.05.
(B) No. The p-value of the appropriate test is less than 0.05.
(C) Yes. The p-value of the appropriate test is greater than 0.05.
(D) Yes. The p-value of the appropriate test is less than 0.05.
(E) Not enough information is given to determine whether there is convincing statistical evidence
answer a show work, please
Answer:
B - No. The p-value of the appropriate test is less than 0.05
Step-by-step explanation:
I found it online in some answer key pdf
From the solution to the question that we have here, the answer is A. There is no convincing evidence that the hours worked decreased after the increase in salary.
The hypothesis formulationH0: u = 13
H1: u < 13
sample size n = 400
bar x = 12.5
mean = 13
How to solve for the t test statistics[tex]t = \frac{x-u}{s/\sqrt{n} } \\\\t = \frac{12.5-13}{6.5/\sqrt{400} } \\[/tex]
= -1.5388
degree of freedom: 400 -1 = 399
∝ = 0.05
Find the p value
p(t < -1.5385)
= 0.062
The p value is greater than the level of significance. We therefore fail to reject the null hypothesis.

Which expression is equivalent to the expression for the perimeter of the larger garden. Select all the apply.
Answer:
Option A, 4X + 40 expression is equivalent to the expression for the perimeter of the larger garden
Step-by-step explanation:
The complete question is
A garden is 15 feet long by 5 feet wide. The length and width of the garden will each be increased by the same number of feet. This expression represents the perimeter of the larger garden: (x+15)+(x+5)+(x+15)+(x+5). Which expression is equivalent to the expression for the perimeter of the larger garden? Select all that apply.
4x+40 2(2x+20) 2(x+15)(x+5) 4(x+15)(x+5) 2(x+15)+2(x+5)Solution
The expression for the perimeter of the larger garden: [tex](x+15)+(x+5)+(x+15)+(x+5)[/tex]
If the given expression is expanded and solved, we get the following
[tex](x+15)+(x+5)+(x+15)+(x+5)\\X+X+X+X + 15+15+5+5\\2X+2X+30+10\\4X +40[/tex]
Hence, option A is correct
Question 1: The sum of two consecutive multiples of 5 is 55. Find these multiples. Question 2: The present age of Sahil's mother is three times the present age of Sahil. After5 years their ages will add to 66 years. Find the present ages. Question 3: The perimeter of a rectangle is 13 cm and its width is 2- cm. Find its length.
Answer:
1] Two consecutive multiples = 50,55. 2] Sahil , Mother current age = 13,42 3] Length of rectangle = 4.5
Step-by-step explanation:
1] Let one multiple of 5 be = n. As there are two consecutive multiples, other multiple = n + 1. Given : sum of two consecutive multiples of 5 is 55
So, 5n + 5(n+1) = 55
5n + 5n + 5 = 55 ; 10n + 5 = 55 ; 10n = 50 - 5 = 50 ; n = 50 / 10 ; n = 5
n {One multiple} = 5 ; Other multiple {n+1} = 5 + 1 = 6
2] Let present age of Sahil be = x. So, present age of Sahil mother = 3x
5 years hence : (x+5) + (3x+5) = 66 {Equation 1}
Solving Eq 1} : x + 5 + 3x + 5 = 66 ; 4x + 10 = 66 ; 4x = 66 - 10 ; 4x = 56
x = 56/4 ; x = 14 {Sahil Current Age}. Mother current age = 3x = 3 x 14 = 42
3] Perimeter of rectangle = 2 (Length + Width). Perimeter = 13 , Width = 2.
So, 13 = 2 (L +2) ; 13 = 2L + 4 ; 2L = 13 - 4 = 9 ; L = 9/2 ; Length = 4.5
