Tamara uses a coupon to save 20% off her purchase at the bookstore. The original cost of Tamara's purchase is d dollars
Answer:
The discount is $0.8d.
Step-by-step explanation:
Given that,
The original cost of Tamara's purchase is d dollars.
Tamara uses a coupon to save 20% off her purchase at the bookstore.
Discount = 20%
Discount is applied to the original cost.
Discount = d-(20/100)d
Discount = 0.8 d
Hence, the discount is $0.8d.
If you are using a compound microscope with an ocular lens with a magnification of 10x and an objective lens of 25x, what is the total magnification of the sample?
Answer:
250×
Step-by-step explanation:
The ocular lens of the compound microscope is 10×
The objective lens of the compound microscope is 25×
Therefore the total magnification can be calculated as follows
= 10×25
= 250
Hence the total magnification of the compound microscope is 250×

Jane and Tannic split the cost of buying a video game. The game costs$25, and the sales is 6% markup. How much do they each pay?
Answer:
$13.25
Step-by-step explanation:
Given data
Cost of game = $25
Markup= 6%
Let us find the total cost of the game
First, the markup cost
=6/100*25
=0.06*25
=$1.5
Now the total cost is
=25+1.5
=$26.5
So, each is expected to pay
=26.5/2
=$13.25
Can 17, 9, and 11 be the side lengths of a triangle?
Answer:
No it cant
Step-by-step explanation:
You have to use the Pythagoras theorem which is a^2 + b^2 = c^2. So 9^2 + 11^2= 202. Then 17 is the hypotenuse so 17^2= 289. They are not equal so they are not.

20,085 rounded to the nearest hundreds place is?
Answer:
20,100
Step-by-step explanation:
hundreds place is the third from the right
Answer:
20,100
Step-by-step explanation:
085 represents 0 hundreds, 8 tens and 5 ones.
That place keeper 0 is rounded up to a 1 because the following '8' is greater than 5.
Thus, the desired rounded off number is 20,100.
Pleaseee Helpp. If the radius is 21 m and area of sector of the circle are 27.72 m2, calculate the angle at the centre of the circle.
Given:
Radius of a circle = 21 m
Area of a sector of the circle = 27.72 m²
To find:
The angle at the center of the circle.
Solution:
The area of a second is:
[tex]A=\pi r^2\times \dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius of the circle and [tex]\theta[/tex] is the central angle.
Putting [tex]\pi=\dfrac{22}{7},\ r=21,\ A=27.72[/tex] in the above formula, we get
[tex]27.72=\dfrac{22}{7}\times (21)^2\times \dfrac{\theta}{360^\circ}[/tex]
[tex]27.72=1386\times \dfrac{\theta}{360^\circ}[/tex]
[tex]27.72=3.85^\circ \times \theta[/tex]
[tex]\dfrac{27.72}{3.85^\circ }=\theta[/tex]
[tex]7.2^\circ=\theta[/tex]
Therefore, the central angle of the sector is [tex]7.2^\circ[/tex].

Answer:
1 : 12
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

Help pls!!!!!!!!!!!!!!
Answer:
160 for each
Step-by-step explanation:
A normal distribution means that mean = median = mode. Furthermore, in a normal distribution, 68% of values are within 1 standard deviation of the mean, 95% of values are within 2 standard deviations, and 99.7% are within 3 standard deviation.
The mean is 150 and the standard deviation is 15. 165 and 135 1 standard deviation away from the mean, so 68% of values are between 135 and 165. This means that 32% of values are not between those values. A normal distributuion is symmetric, so 16% of values are greater than 1 standard distribution and 16% are less. Therefore, 16% of values (160) are less than 135 and 16% of values (160) are greater than 165

Answer:
Step-by-step explanation:
∠EMC = ∠EMD + ∠DMC
∠EMC = 90
∠EMD + ∠DMC = 90
∠EMD + 20 =90
∠EMD = 90 - 20
∠EMD = 70
∠FMD + ∠DMB = 180 {Linear pair}
90 + ∠DMB = 180
∠DMB = 180 - 90
∠DMB = 90
find the x-intercept of the function y=4x+6
Answer:
The x-intercept = -3/2
Step-by-step explanation:
Set y = 0 to find the x-intercepts;
=> y = 4x + 6
=> 0 = 4x + 6
=> 0 - 6 = 4x
=> -6 = 4x
=> -6/4 = x
=> -3/2 = x
Therefore the x-intercept = -3/2

ABDE is a rectangle ED is 8cm BDC is a right-angled triangle bc is 4.5cm ABC is a straight line the area of the rectangle abde is 40cm^2 work out the area of the triangle BDC
also I need working out sooooooo
Answer:
11.25cm^2
Step-by-step explanation:
given the area of the rectangle as 40cm^2, we can get the width of the rectangle.
Area =Length x width
40cm^2 = 8cm x width
we can divide both sides 8 to be left with the width
40/8 = 5cm
so the width is 5cm which is equal to the height of the triangle.
Area of BDC = 1/2 x base x height
BDC = 1/2 x 4.5 x 5
=11.25cm^2
Kathie buys a bottle of fruit juice for $2.50 and a few loaves of bread for $1.20 each.
a. If she spent $8.50, how many loaves of bread did she buy?
b. If she can spend AT MOST $20, how many loaves of bread can she buy?
Answer:
a. 5 loaves, b. 14 loaves
Step-by-step explanation:
a.8.50=2.50+1.20x
6.00=1.20x
5=x
5 loaves
b.20=2.50+1.20x
17.50=1.20x
14.6=x
14 loaves
