dwayne needs 1 1/4 cups of crushed oreos to put in his chocolate pudding and 2/3 cup of oreo crumbs for decoration on the top if he has 3 cups of crushed oreo in all how much will he have left
Answer:
1 1/4 cup left
Step-by-step explanation:
.75 of a third is a fourth, so that would mean that 2/3 is .50, 75% of 2/3, is 0.50, 1/4 is 0.25, so that would mean .75, which is 3/4 cups, so that would mean he needs 1 3/4 cups, so he has 1 1/4 cup left
Ann and Bob split some money in the ratio 4:2. Ann got £4 more than Bob. How much did Bob get?
Answer:
$4
Step-by-step explanation:
A 4:2 ratio is the same as a 2:1 ratio, so Ann receives double what Bob gets.
If Ann gets 8 dollars and Bob gets 4, then Ann would have $4 more than Bob, and it would follow the appropriate ratio.

Given: ΔABC
m∠1=m∠2
D∈ AC , BD = DC
m∠BDC=100°
Find: m∠A, m∠B, m∠C
Answer:
m∠A = 60°, m∠B = 80°, m∠C = 40°Step-by-step explanation:
Since BD = DC, the triangle BDC is isosceles, so
m∠C = m∠2Having m∠BDC = 100°, we can find m∠C
m∠C = 1/2(180° - 100°) = 1/2(80°) = 40°Finding angle B
m∠B = m∠1 + m∠2 = 2*m∠2= 2*40° = 80°Finding angle A
m∠BDA = 180° - m∠BDC = 180° - 100° = 80°m∠A = 180° - (m∠1 + m∠BDA) = 180° - (40° + 80°) = 180° - 120° = 60°Answer:
m<A=60 degrees, m<B=80 degrees, m<C=60 degrees.

Find a solution to the linear equation-2x-2y=8 by filling in the boxes with a valid value of x and y
Step-by-step explanation:
If you want the "root" of the equation...
First get y by itself on one side. You should get y = - x - 8.
Notice that this is the equation of a straight line.
Then let y = 0, and solve for x. You should get x = -8.
So the solution or "root" of the equation is at the point (-8,0)
Answer:
X=0, y=0, x=3
Put the values into the equation. You should get -4,0

CLOTHING A online retailer is running a special on jeans. All pairs of jeans are $39. The function f(x) = 39x models the total cost of buying x pairs of jeans. The retailer also charges $6 flat rate shipping fee. a. Write a function g(x) that represents the cost of purchasing jeans and having them shipped. b. Find the cost of purchasing 3 pairs of jeans before and after shipping
Answer:
a. g(x) = 39x + 6
b. The price before shipping is $117 and the price after shipping is $123
Step-by-step explanation:
To represent the cost of purchasing jeans and shipping them, add 6 to the function, since it is a flat rate.
So, the function will be g(x) = 39x + 6.
Then, use this function to find the cost of 3 pairs of jeans after shipping:
g(x) = 39x + 6
g(3) = 39(3) + 6
g(3) = 117 + 6
= $123
Then, use the original function, f(x) = 39x, to find the price before shipping:
f(x) = 39x
f(3) = 39(3)
= $117
So, the price before shipping is $117 and the price after shipping is $123

A sofa regularly sells for $710. The sale price is $553.80. Find the percent decrease of the sale price from the regular price.
Given:
A sofa regularly sells for $710.
The sale price is $553.80.
To find:
The percent decrease of the sale price from the regular price.
Solution:
We have,
[tex]Decrease\%=\dfrac{\text{Regular price - Sale price}}{\text{Regular price}}\times 100[/tex]
[tex]Decrease\%=\dfrac{710-553.80}{710}\times 100[/tex]
[tex]Decrease\%=\dfrac{156.2}{710}\times 100[/tex]
[tex]Decrease\%=0.22 \times 100[/tex]
[tex]Decrease\%=22\%[/tex]
Therefore, the percent decrease of the sale price from the regular price is 22%.
GR has coordinates g (2, -2) and R (3,8) and it is the result of the
dilation of HM centered at the origin. The coordinates of HM (-1,1) and M (-1.5,-4). Complete the following algebraic description that it represents the transformation of HM. Please help
Answer:
(- 2x , - 2y)
Step-by-step explanation:
A(x, y) ----> A' (kx, ky)
~~~~~~~~
H(- 1 ,1) ----> [k(- 1), k(1)] ----> G(2, - 2) ⇒ k = - 2
M( - 1.5, - 4) -----> [(- 2)(- 1.5) , (- 2)(- 4)] ------> R(3. 8)
k = - 2
Thus, the rule of dilation centered in origin is (- 2x , - 2y)

Answer:
0.0000
Step-by-step explanation:
The sign test can be defined as a statistical method which can be used to test for consistent differences that are in existence between pairs
Now If N is 4, Preal is 0.80 in the predicted direction, and this is a 0.05 1-tail. Using the sign test, the power is going to be 0.0000.

C: 28 tiles in 85 minutes
D: 1 tile in 3 minutes
E: 1 tile in 4 minutes
Answer:
I think C and E
Step-by-step explanation:
meg played at lace of 3.3333 tiles a minute so has to be over 25 tiles
The correct options are C and D.
Important information:
Meg laid 15 tiles in 50 minutes.Jessica worked for 85 minutes at a faster rate per tile than Meg.Rates:The rate per tile of Meg is:
[tex]\text{Rate}=\dfrac{\text{Time}}{\text{No. of tiles}}[/tex]
[tex]\text{Rate}=\dfrac{50}{15}[/tex]
[tex]\text{Rate}=3.333...[/tex]
Calculate the rates per tile for each option.
[tex]\frac{85}{20}=4.25[/tex]
[tex]\frac{85}{24}=3.54167...[/tex]
[tex]\frac{85}{28}=3.0357...[/tex]
[tex]\frac{3}{1}=3[/tex]
[tex]\frac{4}{1}=4[/tex]
From the above calculation is clear that the time spent per tile is less than Meg's rate in options C and D.
Therefore, the correct options are C and D.

C. no real or complex solutions
D. two real solutions
Pls help!
Answer:
C.
Step-by-step explanation:
The quadratic equation has two complex (nonreal) solutions option (B) is correct.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:

We have a quadratic equation:
3x² + 4x = - 5
or
3x² + 4x + 5 = 0
D = b² - 4ac
b = 4, a = 3, c = 5
D = (4)² - 4(3)(5)
D = 16 - 60
D= -44
D < 0

A survey of 80 randomly selected companies asked them to report the annual income of their presidents. Assuming that incomes are normally distributed with a standard deviation of $30,000, determine the 90% confidence interval estimate of the mean annual income of all company presidents. Interpret the statistical results.
Answer:
The 90% confidence interval estimate of the mean annual income of all company presidents is ($579,545, $590,580).
Step-by-step explanation:
The information provided is:
[tex]n=80\\\sigma=30,000\\\bar x=585062.50\\\text{Confidence level} = 90\%[/tex]
The critical value of z for 90% confidence level is, 1.645.
Compute the 90% confidence interval estimate of the mean annual income of all company presidents as follows:
[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\\\\=585062.50\pm 1.645\times\frac{30000}{\sqrt{80}}\\\\=585062.50\pm5517.50\\\\=(579545, 590580)[/tex]
Thus, the 90% confidence interval estimate of the mean annual income of all company presidents is ($579,545, $590,580).
This interval implies that there is 90% probability that the true mean annual income of all company presidents is within this interval.
