a vase costs $2 bridget has some money if she gets $4.45 more she can buy 5 vases how much money does she have
Answer:
Bridget has $5.55.
Step-by-step explanation:
First let's find how much money Bridget needs to buy 5 vases. To do this, multiply the cost per vase by the amount of vases she wants to buy:
2 * 5 = 10
It would cost $10 to buy 5 vases.
Bridget needs $4.45 in order to buy 5 vases. So, to find how much money she already has, subtract the amount of money she needs from the total cost of the 5 vases:
10 - 4.45 = 5.55
Bridget has $5.55.
Answer:
$ 5.55
Step-by-step explanation:
Find the price of 5 vases
Cost of 5 vases = 5 * 2 = $ 10
She needs $4.45 to buy 5 vases. If we subtract this 4.45 from $10, the result will be the money she has already with her
Money Bridget has = 10 - 4.45
= $ 5.55

pls answer my question
Answer:
x = 23
Step-by-step explanation:
Exterior angles equals the sum of opposite interior angles.
2x+ 3 + 51 = 100
Combine like terms.
2x + 54 = 100 {Subtract 54 from both sides}
2x = 100 - 54
2x = 46 {Divide both sides by 2}
x = 46/2
x = 23

Part A and Part B for Max's car together cost $1,693 dollars, Part A cost $58 dollars
more than twice what Part B cost. How much did each part cost?
Answer:
Part A: 1148
Part B: 545
Step-by-step explanation:
Part A: 2x + 58
Part B: x
2x + 58 + x = 1693
3x + 58 = 1693
3x = 1635
x = 545
Part A: 2x + 58 = 2(545) + 58 = 1148
Part B: x = 545
Find the amount of interest to be paid.
Principal: $780
Annual Rate of Interest: 12 1/2%
Time: 6 months
Use the formula: i = prt (principal, rate, time)
Answer:
P = 780
R = 12 1/2%
T = 6
780 x 12 1/2% x 6 = $2808.005
A researcher claims that the variation in the salaries of elementary school teachers is greater than the variation in the salaries of secondary school teachers (the claim). A random sample of 30 elementary school teachers has a variance of $ 8324, and a random sample of 30 secondary school teachers has a variance of $2862. At α= 0.05, can the researcher conclude that the variation in the elementary school teachers' Salaries is greater than the variation in the secondary teachers' salaries? Use the P-value method.
Assume that all variables are normally distributed.
a. State the hypotheses and identify the claim.
b. Find the critical value.
c. Compute the test value.
d. Make the decision.
e. Summarize the results.
Answer:
a
The null hypothesis is [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]
The alternative hypothesis is [tex]H_a : \sigma_1 ^2 > \sigma^2_2[/tex]
b
[tex]F_{critical} = 1.8608[/tex]
c
[tex]F = 2.9085[/tex]
d
The decision rule is
Reject the null hypothesis
e
There is sufficient evidence to support the researchers claim
Step-by-step explanation:
From the question we are told that
The first sample size is [tex]n_1 = 30[/tex]
The sample variance for elementary school is [tex]s^2_1 = 8324[/tex]
The second sample size is [tex]n_2 = 30[/tex]
The sample variance for the secondary school is [tex]s^2_2 = 2862[/tex]
The significance level is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]
The alternative hypothesis is [tex]H_a : \sigma_1 ^2 > \sigma^2_2[/tex]
Generally from the F statistics table the critical value of [tex]\alpha = 0.05[/tex] at first and second degree of freedom [tex]df_1 = n_1 - 1 = 30 - 1 = 29[/tex] and [tex]df_2 = n_2 - 1 = 30 - 1 = 29[/tex] is
[tex]F_{critical} = 1.8608[/tex]
Generally the test statistics is mathematically represented as
[tex]F = \frac{s_1^2 }{s_2^2}[/tex]
=> [tex]F = \frac{8324 }{2862}[/tex]
=> [tex]F = 2.9085[/tex]
Generally from the value obtained we see that [tex]F > F_{critical }[/tex] Hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to support the researchers claim

Kendra is buying a Nintendo Switch with a price tag of $300. The sales tax rate where Kendra is purchasing the
Switch is 9.5%. How much will Kendra pay altogether for the Switch?
Answer: So for the 9.5% percent I'm not sure if you mean by 9.5% off the price or more for the price so Ill just do both
If you subtract $300 from 9.5% you get 271.5 US$
But if you add $300 to 9.5% you get 328.5 US$

A store had 50 bottles of olive oil. Each week, 40% of the olive oil bottles were sold and 20 new bottles arrived in shipments. Which recursive function best represents the number of bottles in the store, given that f(0) = 50?
Answer:
f(n) = f(n-1)*.6 + 20
Step-by-step explanation:
f(0) = 50
f(n) = f(n-1)*.6 + 20
In fact, since f(0) = 50, f(n) = 50.

You are canning 40 cups of applesauce. You have 20 glass jars, each of which will hold 134 cups of applesauce. Choose the correct explanation(s) that explain why you do not have enough jars.
You do not have enough jars because 20 jars will only hold 35 cups of applesauce.
You do not have enough jars because you have enough applesauce left to completely fill 2 more jars, and almost fill a third jar.
You do not have enough jars because you need a total of 40×134=70 jars.
You do not have enough jars because the 20 jars would need to hold 2 cups each, but each holds 14-cup less than that.

ABCDE is a
regular pentagon
find the angles of ADC?
Answer:
Since this regular polygon has 5 vertices (implied from the ABCDE), it's a regular pentagon. (This means an equilateral, equiangular pentagon.) So, 360 deg./5 =72 deg., and 180 - 72 = 108).
