Answer:
Step-by-step explanation:
(6x + 2)° + 42° + 58° = 180°
6x + 2 = 180 - 100
6x = 78
x = 13
Answer:
13
Step-by-step explanation:
There are 180 degrees in a triangle
58 + 42 + (6x +2 ) = 180
98 + (6x + 2) = 180
Subtract 98 from 180.
6x +2 = 82
Subtract 2 from 82
6x = 80
x = 13.333 or 40/3

h(-3)h(-3)=(1)(1)=1
Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer:
[tex]x = 25[/tex]
Step-by-step explanation:
The angles are vertical since they form from two lines crossing at a point and they share a same vertex.
Vertical angles are equal so
[tex]4x - 25 = 75[/tex]
[tex]4x = 100[/tex]
[tex]x = 25[/tex]
In August, Emily's Clothing Store sold 98 long sleeve shirts with the ratio of short sleeve to long sleeve being 3:7. How many short sleeves were sold?
Answer:
the number of short sleeves sold is 42
Step-by-step explanation:
The computation of the number of short sleeves sold is shown below:
Given that
The clothing store sold 98 long sleeve shirts
And, the ratio of short sleeve to long sleeve is 3:7
So, the number of short sleeves sold is
= 98 × 3 ÷ 7
= 42
Hence, the number of short sleeves sold is 42

If I have the letter x after a number, what does it mean?
Ex. 20x = 5
Answer:
It means that 20 times x is 5
also the answer to that problem (20x=5) is 1/4
Step-by-step explanation:
20x means
20 * x
and since 20 * x = 5
divide 5 and 20
5/20 = 1/4

Find the surface area of the prism
Answer:
[tex]400\ cm^2[/tex]
Step-by-step explanation:
1. Approach
The surface area of an object is the two-dimensional area around the object. If one was going to wrap the figure in paper, then the surface area would be the amount of paper one would need to cover the entirety of the object. To find the surface area of an object, calculate the area of each face of the object and then add up the results,
2. Find the area of each face
The area of all the rectangular faces can be found by using the formula to find the area of a rectangle, ([tex]length*width[/tex]). Substitute in each of the values,
[tex]17*7=119[/tex]
[tex]15*7=105[/tex]
[tex]8*7=56[/tex]
Now find the area of the triangular faces. This can be done by using the formula for the area of a triangle, ([tex]\frac{(length)*(width)}{2}[/tex]). Substitute in the given values,
[tex]\frac{(15)*(8)}{2}=60[/tex]
[tex]\frac{(15)*(8)}{2}=60[/tex]
3. Find the total surface area
Now add up the values of the area for each of the faces of the prism,
[tex]119+105+56+60+60[/tex]
[tex]=400[/tex]

48. A wire is securely attached from the top of
a 26-foot pole to a stake on the ground
14 feet from the base of the pole. Find the
length of the wire to the nearest tenth of a
foot.
A. 21.9 feet
B. 24.3 feet
C. 28.7 feet
D. 29.5 feet
Answer:
D. 29.5 feet
Step-by-step explanation:
1) First you use the pythagorean theorem a^2+b^2=c^2
2) 26^2+14^2=c^2 The wire is the hypotenuse.
3) Simplify the equation. 676+196=c
4) 872=c
5) Find the square root of 872 and round to the nearest tenth.
6) Your answer is 29.5 feet.

At 7am there was 4 inches of snow on the ground. After that, the snow fell at a rate of 1.5 inches per hour. Equation:
Answer:
y(t) = 4 + 1.5t
.
Step-by-step explanation:
Initial amount of snow = 4 inches
Fall rate of snow = 1.5 inch per hour
Equation to model the scenario goes thus :
Initial amount of snow + (fall rate of snow * number of hours)
Let the number of hours = h
4 inches + (1.5 inch per hour * h)
Equation, y(t) becomes ;
y(t) = 4 + 1.5t

factorise it
[tex]v[/tex]
Answer:
2(x – ½)(x + ½)
Step-by-step explanation:
2x² – ½
The above expression can be factorised as follow:
2x² – ½
2 is common to both 2 and ½. Thus,
2x² – ½ = 2[x² – ¼]
Recall
(½)² = ¼
Thus,
2[x² – ¼] = 2[x² – (½)²]
Difference of two squares
2(x – ½)(x + ½)
Therefore,
2x² – ½ = 2(x – ½)(x + ½)

At middle school lunch in the cafeteria, 60% of the students pack a lunch and 40% buy a lunch. Of the students who pack a lunch, 70% have a cookie. What is the percent of the students who have a cookie at lunch?
Answer:
42%
Step-by-step explanation:
The computation of the percentage is shown below:
Here we assume that there are 100 students
So according to the question
60% of the students would pack the lunch i.e. 60 students
And, 40% of the students buy a lunch i.e. 40 students
Now the students who pack the lunch they have 70% of cookie
So, 70% of 60 students = 42 students
Now the percentage is
= 42 students ÷ 100 students
= 42%

Part A
What is the value of x?
Show your work.
Part B
Describe two different ways you could find measure of angle CFD. What is the measure of this angle?
Answer:
Step-by-step explanation:
Part A
Since, all angle formed at point F lie on a straight line CE.
Therefore, sum of angles ∠AFE, ∠AFB, ∠CFB will be 180°.
(7x + 4) + (8x + 6) + (6x + 2) = 180
21x + 12 = 180
21x = 168
x = 8
Part B
Two lines CD and AE intersect each other at point F.
Therefore, ∠AFE ≅ ∠DFC [Vertically opposite angles]
m∠CFD = (7x + 4)°
= 7(8) + 4
= 60°
Since, all angles formed at point F on a straight line AD are linear angles,
m∠AFB + m∠CFB + m∠CFD = 180°
(8x + 6) + (6x + 2) + m∠CFD = 180°
14x + 8 + m∠CFD = 180
m∠CFD = 172 - 14x
= 172 - 14(8)
= 172 - 112
= 60°

A brick of lead weighs 6,328 grams and has the following dimensions: length of 20 cm, height
of 8 crn, and width of 35 mm. What is the approximate density of the lead? Round to the
nearest tenth
Answer:
11.3
Step-by-step explanation:
Volume: L * W * H
L = 20
W = 8
H = 35 mm = 35/10 = 3.5 cm
V = 20 * 8 * 3.5
V = 560 cm^3
Density = m/v
Density = 6328 / 560
Density = 11.3
