Answer: 38
Step-by-step explanation:
3.8=19/5
u have to flip the reciprocal to divide by fraction so 1/10 will be just 10
Then u get 19/5 x 10
You can reduce the GCF so it would be 19 x 2
19 x 2 = 38
Or you can plug it into your calculator (3.8 x .1)

A student claims that the equation y = 7 is not a linear equation because it does not have the form y = mx + b. Do you agree or disagree? Explain.
Answer:
Yes i agree
Step-by-step explanation: The equation is there for a reason and if an answer does not fir the equation it can be linear so therefore the equation y=7 is not linear.
Line passes through ( 2,4 ) with slope = 3
Answer:
the slope intercept-form of an equation of a line is y=mx+b
Given that the slope is 3 and a point on the line is P(-2, 4), then
m=3 and from the point (-2, 4), x=-2 and y=4.
Step-by-step explanation:
y=mx+b.
4=3(-2)+b Now solve for b.
4=-6+b
4+6=b
10=b
Now you know b=10 and you already know the slope m=3. Substitute these values into y=mx+b. When you do you will get y=3x+10. This is your answer in slope intercept form.
What does the question mark stand for in the following when you factorise:
4d3 + 6de =? (2d2 +3e
Answer:
Question mark stands for 2d
Step-by-step explanation:
Here, we want to get what the question marks stands for
As we can see, the left was factorized to give the right
So, we have that ;
4d^3 + 6de = 2d(2d^2 + 3e)
so the question mark stands for 2d

Which expressions are equal to
23 ?
Answer: The first option and the third option
Step-by-step explanation: You are not supposed to find something equivalent to the fraction, you have to divide the fraction.
13824 ÷ 8 = 1728
Then it is when you try to find a number equivalent to 1728. 12 to the power of 3 equals 1728
12×12=144
144×12=1728
12 to the power of 3 is equivalent to 1728
These are wrong: 2 to the power of three is unequivalent and so is 12 to the power of 6 and 6 to the power of 3
2 to the power of 6 is 64
2×2=4
4×2=8
8×2=16
16×2=32
32×2=64
3 to the power of 3 is 27
3×3=9
9×3=27
64 times 27 equals 1728 so it's equivalent and that means that our answers are A, the 1st option , and C, the 3rd option
The equivalent expression will be;
⇒ 12³

Lisa needs 250 yards of yarn to knit a hat. She has 185 yards of yarn and needs to buy the rest. How many yards of yarn does she need to buy?
Use the variable y to represent the number of yards of yarn she needs to buy.
Which equation represents this situation and its solution?
250y = 185; y = 55
y + 185 = 250; y = 65
y + 250 = 185; y = 65
185y = 250; y = 55
Answer:
it's answer is y + 185 = 250; y = 65

Im having trouble with finding the distance. a
Answer:
The answer is below
Step-by-step explanation:
From the image:
∠P + ∠Q = 180° (consecutive angles are supplementary)
78 + ∠Q = 180
∠Q = 180 - 78
∠Q = 102°
∠RQN = 360° - 305° =(sum of angle in a point)
∠RQN = 55°
∠RQN + ∠RQP = 102°
∠RQP = 102 - 55 = 47°
a) Let PR = x
Using cosine rule:
[tex]x^2=600^2+950^2-2(900)(600)cos(47)\\\\x^2=485021.9\\\\x=\sqrt{485021.9} \\\\x=696 \ m[/tex]
Therefore PR = 696 m
b) Let ∠RPQ be A°
Using sine rule:
[tex]\frac{sin(A)}{600} =\frac{sin(47)}{696} \\\\sin(A)=\frac{sin(47)}{696} *600\\\\sin(A)=0.6304\\\\A=sin^{-1}(0.6304)\\\\A=39^0[/tex]
∠RPQ = 39°
Hence the bearing of R from P = ∠NPR = 78° - 39° = 39°

What is the interest on Rr 20,000 if the interest rate is 15%?
Answer: Rr.3,000
Step-by-step explanation:
The interest is the amount that accrues on a principal that was invested or a cost that was incurred.
It is based on a certain interest rate which in this case is 15%.
The principal is Rr. 20,000.
Interest = Principal * Interest rate
= 20,000 * 15%
= Rr.3,000
Jefferson Elementary has a rectangular playground. A scale drawing of the playground is shown below.
10.5 cm
4.2 cm
The shortest side of the playground has an actual length of 33.6 meters.
What is the actual area, in square meters, of the playground?
I'm sorry if I get this wrong, but there isn't enough evidence.
If we think about the shorter side being 4.2 cm, then just divide 33.6 by 4.2 to give it a ratio. 33.6 / 4.2 is 8. The ratio of the scale drawing to the actual playground would be 1 : 8.
The longer side is 10.5, so just multiply that by 8. You'd get 84 meters. The only part left is getting the area.
Multiply 84 x 33.6 and you'd get 2822.4
The answer would be 2,822.4 squared.

The expression (x+6)² is simplified as x²+12x+36.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
A) (3x-2)(x+5)
= 3x²-2x+15x-10
= 3x²+13x-10
B) (3x-8)(3x+8)
= (3x)²-8²
= 9x²-64
C) 5x(x-1)(x+7)
= (5x²-5x)(x+7)
= 5x²(x+7)-5x(x+7)
= 5x³+35x²-5x²-35x
= 5x³+30x²-35x
D) (x+6)²
= x²+12x+36
E) (x-2)(x-8)
= x(x-8)-2(x-8)
= x²-8x-2x+16
= x²-10x+16
So, A→2, B→5, C→1, D→3, E→4
Therefore, the expression (x+6)² is simplified as x²+12x+36.
