Segments AB, DC and Ec intersect at point C. Angel DCE measures 148. Find the value of x.
The image is attached.
Answer:
x = 16°
Step-by-step explanation:
Segment AB, segment DC and segment EC all intersect at point C.
Here, we are told angle DCE measures 148°.
This is a semi-circle, and the total angle of a semi-circle is 180°.
Which means, x+x+148 = 180
Solving for x, we have:
x+x+148 = 180
2x + 148 = 180
2x = 180 - 148
2x = 32
[tex]x = \frac{32}{2}[/tex]
x = 16°
The value of x is 16°
If you need 4 tables spoons of golden syrup to make 10 cupcakes, how many tables spoons of golden syrup will you need to make 4 cupcakes.
Answer:
1.6 tablespoons
Step-by-step explanation:
Let’s make a proportion
syrup/cupcakes=syrup/cupcakes
4 tablespoons are needed for 10 cupcakes and x tablespoons are needed for 4 cupcakes.
4/10=x/4
Now we have to solve for x. x is being divided by 4. To reverse this, multiply both sides by 4, because multiplication is the opposite of division.
4*4/10=x/4*4
The 4s on the right will cancel, so we are left with:
4/4*10=x
1.6=x
So, 1.6 tablespoons are needed for 4 cupcakes.

[tex]y = 4^x \quad \to\quad y = - \frac 2 3 (4^{x+7}) - 5[/tex]
[tex]y=4^x[/tex]
OK, we'll go in steps. First a reflection through the x axis, which negates y.
[tex]y = -4^x[/tex]
Now a vertical scaling of 2/3
[tex] y = -\frac 2 3 \cdot 4^x[/tex]
Now we shift seven units to the right,
[tex] y = -\frac 2 3 \cdot 4^{x+7}[/tex]
Now down five,
[tex] y = -\frac 2 3 \cdot 4^{x+7} - 5[/tex]
There it is.
Answer: reflection thru x axis, vertical scale 2/3, right shift 7, down 5, second choice

Step-by-step explanation:
The statistics(60%) used provide facts on the topic that make the source credibleFind the value of x and y
Answer:
x = 45
y = 20
Step-by-step explanation:
Set the x-variables and y-variables with its corresponding ones, like so:
4x - 35 = 3x + 10
Subtract 3x from both sides:
x - 35 = 10
Add 35 to both sides:
x = 45
Solving for y:
2y - 5 = y + 15
Subtract y from both sides:
y - 5 = 15
Add 5 to both sides:
y = 20
Answer:
By vertically opposite angle
2y-5=y+15
y=20°
4x-35=3x+10
x=45°

Answer:
x=24 y=19
Step-by-step explanation:
2y=y+19
y=19
2x-8=x+16
x=16+8
x=24
Answer:
x = 24
y = 19
Step-by-step explanation:
Set the expressions with the x-variables together, and the y-variables together, like so:
2x - 8 = x + 16
Subtract x from both sides:
x - 8 = 16
Add 8 to both sides:
x = 24
Solving for y:
2y = y + 19
Subtract y from both sides:
y = 19
Find the diameter of the object.
A circular steering wheel with radius labeled 0.8 feet.
diameter:
ft
in order to find the diameter, you multiply the radius times 2.....so you would do 0.8 times 2 which equals 1.6
The diameter of the circular steering wheel is 1.6 feet
How to determine the diameter?The radius of the object is given as:
r = 0.8 feet
Multiply both sides by 2, to determine the diameter
d = 2 * 0.8 feet
Evaluate
d = 1.6 feet
Hence, the diameter of the circular steering wheel is 1.6 feet

4) The diameter of a circle is 32m. The radius is represented by 4(x + 2).
Part A: Write an equation you can use to find the value of x.
Part B: What is the value of x?
Answer:
The value of x is 2
Step-by-step explanation:
Diameter = 2r -------------------------------------------------------------------(1)
where r is the radius
The value of the diameter = 32 m and radius is given to be 4(x+2)
substitute the above into equation (1) and then solve for x
32 = 2 [ 4(x + 2)]
first open the inner bracket
32 = 2[4x + 8}
then open the outer bracket
32 = 8x + 16
subtract 16 from both-side of the equation
32 - 16 = 8x +16 - 16
16 = 8x
Divide both-side of the equation by 8
16/8 = 8x/8
2 = x
x = 2
Therefore, the value of x is 2

In two or more complete sentences discuss the advantages and disadvantages of investing in a 529 plan versus investing in a money market account.
Answer:
Step-by-step explanation:
A 529 plan (Qualified tuition plan) is a tax-advantaged savings plan for future education costs while a money market account refers to a investment or a deposit with a financial institution that earns interest based on the current rates.
Money market deposit accounts are better choices than 529 plan for money you might need to tap at a moment’s notice to cover an emergency or an unexpectedly large expense. They pay higher interest than ordinary savings accounts and give you immediate access to your money
While in 529 savings plan, If you don’t use the money invested for college tuition, you will be penalized 10 percent when you withdraw the money to use it for something else. In addition, both your state and the federal government will tax the earnings on your account in your current tax bracket.
The basic advantage of 529 plan over money market account is the tax-advantage that is the amount invested or withdrawn is tax free. It also has high return and funds from it can be used for another beneficiary who is a qualified family member. Whereas the disadvantage is that the 529 plan is a specified fund for future education purposes. This makes it restricted as the fund can not be transferred for a different use. Unlike the money market account whose use is not restricted. It can be withdrawn to meet diverse financial needs including education. More so, funds in the money market account are insured and can be easily accessed.
In essence, the 529 plan is a specific investment while a money market account is more general in nature.

Find the measure of RPS
A. 45
B. 36
C. 60
D. 64
Answer:
x=8
RPS = 36
Step-by-step explanation:
QPS = 180
The two angles that form QPS
QPR + RPS = 180
7x+88 + 3x+12 = 180
Combine like terms
10x+100 =180
Subtract 100 from each side
10x = 180-100
10x = 80
Divide by 10
x =80/10
x = 8
RPS = 3x+12
= 3(8)+12

A sporting goods company sells a tent with the dimensions shown. The company wants to introduce a new, larger tent that is geometrically similar to the original tent but with a height of 6 feet. How will the volume of the new tent compare with the volume of the original tent?
Answer:
The volume of the new tent will be 3/2 times the volume of the original
Step-by-step explanation:
The original tent is a triangular prism, which missing dimensions of the tent are:
base (b): 6 ftheight (h): 4 ftlength (l): 7 ftVolume of the original tent:
V = 1/2*b*h*l
The only difference between the new and the original tent are their heights. Let's call h' = 6 ft to the height of the new tent.
Volume of the new tent:
V' = 1/2*b*h'*l
Dividing V' by V:
V'/V = (1/2*b*h'*l)/(1/2*b*h*l)
V'/V =h'/h
Replacing with data:
V'/V =6/4
V' = 3/2*V
