what is 200x149 who can answer that for me i need help on this my teacher said i cant use couculater
Answer:
29,800
Step-by-step explanation:
that will be 149 x 2 which equals 298
149
×2 Multiply 9 × 2 = 18
------ Keep the 8 carry the 1 multiply 4 by 2 then add 1 finally multiply 2 by 1
298
Then add two zeros at the end since we're multiplying a number with two zeros. (This method only works for numbers that end with zeros)
Final answer: 29800
Ashley has baked 17 cakes for a bake sale. She can bake 2 cakes with each additional stick of butter
she buys. How many additional sticks of butter does she need in order to make 41 cakes?
WRITE THE EQUATION THEN SOLVE PLEASEEEE. THANK YOU SO MUCH
Answer:
12 additional sticks of butter
Step-by-step explanation:
First, create an equation. Let y represent the number of additional sticks of butter needed, and let x represent the number of cakes made.
y = [tex]\frac{x}{2}[/tex] will be the equation.
Since she has already baked 17 cakes, she will need to bake 24 more cakes to make 41 cakes.
Plug in 24 as x into the equation, and solve for y:
y = [tex]\frac{x}{2}[/tex]
y = [tex]\frac{24}{2}[/tex]
y = 12
So, she will need 12 additional sticks of butter

Hi there!
[tex]\large\boxed{\text{Gradient = -1}}[/tex]
We can find the slope using the slope formula:
Slope = (y2-y1)/(x2-x1)
Plug in the given coordinates:
Slope = (1 - 5)/(7 - 3)
Simplify:
Slope = -4/4
Slope = -1

Answer:
[tex]x=4[/tex]
Step-by-step explanation:
start by squaring both sides:
[tex](\sqrt{-8+3x} )^2=(2)^2[/tex]
squaring a square root cancels it out:
[tex]-8+3x = 4[/tex]
solve for x by first adding 8 to both sides:
[tex]3x=12[/tex]
then divide both sides by 3:
[tex]x=4\\[/tex]
Max claims that a point on any line that is perpendicular to a segment is equidistant from a segment's endpoints. Charlene claims that the line must be a perpendicular bisector for a point on the line to be equidistant from a segment's endpoints.
Answer:
Charlene claim is true.
Step-by-step explanation:
Max claims that a point on any line that is perpendicular to a segment is equidistant from a segment's endpoints.
It is not necessary as shown in the diagram (a).
Charlene claims that the line must be a perpendicular bisector for a point on the line to be equidistant from a segment's endpoints.
It is true as shown in the diagram (b).
So, Charlene claim is true.

the area of this rectangle = ___ square cm
Answer:
300cm
Step-by-step explanation:
to get the area of a rectangle, all you have to do is (bh) or base * height. in this case, the base is 20cm and the height is 15cm. once you multiply the two lengths you will get 300 meaning that the area of this rectangle is 300 cm.
The required area of a rectangle is 300 square cm which is given in the figure.
What is the area of the rectangle?The area of a rectangle is defined as the multiplication of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have been given a rectangle that has :
The length of the side = 20 cm
The width of the side = 15 cm
The area of a rectangle = The length of the side × The width of the side
The area of a rectangle = 20 cm × 15 cm
Apply the multiplication operation,
The area of a rectangle = 300 square cm
Therefore, the required area of a rectangle is 300 square cm.

Mikes truck can drive 115 miles on 5 gallons of gas. How many miles can be driven with 11 gallons of gas, using the same mpg?
Answer:
253 miles
Step-by-step explanation:
Ratio:
115:5 and x:11
Method 1:
115/5 = x/11
1265 = 5x (cross multiplying)
x = 253 miles
Method 2:
11/5 = 2.2
2.2 x 115 = 253
253 miles
Method 3:
115 / 5 = 23
23 x 11 = 253
253 miles

Answer:
1) 40
2) 118
3) 71
Step-by-step explanation:
3) is the easiest. All interior angles add to 180
Angle 3 = 180 - 62 - 47
Angle 3 = 71
2) Angle 2 is on the same straight line as 62 and together they equal 180
Angle 2 = 180 - 62
Angle 2 = 118
1) Using 22, Angle 2 and the knowledge that all interior angles equal 180
180 - 22 - 118 = Angle 1
40 = Angle 1

by showing the diagonals are congruent. Show all work.
A(0, -3), B(-4, 0), C(2,8), D(6.5)
Answer:
Step-by-step explanation:
If the diagonals of the rectangle are congruent,
AC = BD
By using formula to calculate the distance between two points,
Distance between two points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance between A(0, -3) and C(2, 8),
AC = [tex]\sqrt{(8+3)^2+(2-0)^2}[/tex]
= [tex]\sqrt{125}[/tex]
= [tex]5\sqrt{5}[/tex]
Similarly, distance between two points B(-4, 0) and D(6, 5),
BD = [tex]\sqrt{(5-0)^2+(6+4)^2}[/tex]
= [tex]\sqrt{125}[/tex]
= [tex]5\sqrt{5}[/tex]
Therefore, both the diagonals are congruent.
Hence, given quadrilateral ABCD is a rectangle.

The force, F (Newtons), between two
objects is inversely proportional to the
square of the distance, d (metres),
between them.
The force is 0.35 Newtons when the
distance between the objects is 8 metres,
Work out F (rounded to 2 DP) when
d = 7 metres.
F
Newtons
Answer:
F=0.46N
Step-by-step explanation:
[tex]F[/tex]∝[tex]\frac{1}{d^{2}}[/tex],
[tex]F=\frac{k}{d^{2} } \\[/tex]
[tex]F=0.35N, d=8m\\[/tex]
[tex]0.35=\frac{k}{8^{2} }[/tex]
[tex]k=0.35\times 8^{2} \\\\k=22.4\\F=\frac{22.4}{d^{2} } \\d=7m, F=\frac{22.4}{7^{2} } =0.46N[/tex]
If f(x) = 8 – 10x and g(x) = 5x + 4, what is the value of (fg)(–2)?
–196
–168
22
78
Answer:
-168
Step-by-step explanation:
because f(x) = 8 - 10xg(x) = 5x + 4
(fg)(x) = (8 - 10x)(5x + 4)(fg)(x) = 40x + 32 - 50x^2 - 40x(fg)(x) = 32 - 50x^2
(fg)(-2) = 32 - 50(-2)^2(fg)(-2) = 32 - 200(fg)(-2) = -168
If g(x) = 4x2 - 16 were shifted 9 units to the right and 1 down, what would the new equation be? A. h(x) = 4(x + 9)2 – 17
B. h(x) = 4(x – 9)2 – 17
C. h(x) = 4(x = 17)2 - 9
D. h(x) = 4(x - 7)2 + 16
Answer:
Step-by-step explanation:
If you move down 1 unit, you simply subtract 9 units from the given equation.
g(x) = 4x^2 - 16 - 1
g(x) = 4x^2 - 17
Shifting right is a little bit tricky. To shift right, you have to do the opposite of what you would do on the number line. The x has to become x - 9 because the x value (you will learn later) is part of a distance and distances always subtract one from the other.
The wrong way to do it is in answer A.
B is the correct answer
h(x) = 4(x - 9)^2 - 17

Answer:
x=40
Y= 35
Angle AEC= 55
Step-by-step explanation:
Answer:
[tex]x = 40 \\y = 35 \\\angle AEC = 55^\circ[/tex]
Step-by-step explanation:
Find x :
[tex]( 3x + 5)^{\circ} + ( x +15)^{ \circ} = 180 ^{\circ}[/tex] [tex][ \ straight \ line \ angles \ ][/tex]
[tex]3x + 5 + x + 15 = 180\\\\4x + 20 = 180 \\\\4x = 160 \\\\x = 40[/tex]
[tex]\angle AED \ = 3x + 5 = 125 ^{ \circ}[/tex]
[tex]\angle DEB = (x + 15 ) = 40 + 15 = 55^{ \circ}[/tex]
Find y :
[tex]( y + 20)^{ \circ} + (4y - 15)^{ \circ} = 180^{\circ}\\\\y + 20 + 4y - 15 = 180\\\\5y + 5 = 180\\\\5y = 175\\\\y = 35[/tex]
[tex]\angle AEC = ( y + 20 ) = 35 + 20 = 55^\circ\\\\\angle BEC = (4y - 15) = 4(35) -15 = 140 - 15 = 125^\circ[/tex]
The area of a opening rectangular window is to be 440 square centimeters. If the length measures x centimeters and the width measures x-2 centimeters, what are the dimensions?
Answer:
[tex]L=1+20i[/tex]
[tex]B=3+20i[/tex]
Step-by-step explanation:
From the question we are told that:
Area [tex]A=440cm^2[/tex]
Generally the equation for For Area is mathematically given by
[tex]A=L*B[/tex]
[tex]A=x*(x-2)[/tex]
Therefore
[tex]x^2-2x-440=0[/tex]
[tex]x=1+20i[/tex]
Therefore The Dimensions are
[tex]L=1+20i[/tex]
[tex]B=1+20i+2[/tex]
[tex]B=3+20i[/tex]
